With external walk on glass we are able to supply a number of different finishes to prevent slipping due to water build up on the surface. This ranges from sandblasting of the glass through to a ceramic anti slip frit enamel, painted and baked into the top surface of the glass.
All glass floors are designed to be subjected to a specific uniformly distributed load and concentrated point load as specified for the use of the building they are being fitted within. As such the glass specification can change greatly but, as a minimum, all walk on glass is supplied in a toughened/laminated glass make up consisting of three layers of 10mm clear toughened safety glass and two intermediate 1.5mm PVB interlayers.
Most walk on glass elements are designed to fit flush with the surrounding floor finishes thus providing a seamless transition from one finish to the other, the Glazing Innovations team can work with your construction team to create the required upstand and aperture detail to produce both a guaranteed water proof rooflight installation and the required flush perimeter finish. | materials_science |

Visit our gallery or showroom to see examples of some of the work we’ve done. We fabricate several types of countertop surfaces; Decorative Laminate, Acrylic Solid Surface, Wood Veneer, and Solid Wood (Butcher Block).
Below are some of the specifics of each product.
Acrylic Solid Surface: Our most popular brands are Livingstone™, Samsung Staron™, Corian™, and LG Hi-Macs™.
• Unlike granite, acrylic solid surface is a non-porous material, which means it doesn’t absorb bacteria and isn’t susceptible to mold or mildew. This also means there is no sealing or costly maintenance required.
• Proper fabrication of solid surface countertops gives a seamless appearance, meaning that any seams will be inconspicuous. Specially formulated adhesives manufactured to match the color and pattern of your choosing are used to create the perfect look for your kitchen design.
• Coordinating acrylic solid surface countertops with plumbing fixtures requires details of the sink, faucet, and other plumbing components like sprayers or integrated soap dispensers. We are happy to provide and install an undermount sink of your choice, which eliminates the problem of crumbs or other debris becoming stuck on the rim of a traditional drop-in sink. A drain board can also be carved into the countertop to allow water to drain directly into the sink. Traditional drop-in sinks can also be used if the customer so desires.
• Cove backsplash – A cove backsplash is formed by using the solid surface countertop material and the above mentioned matching adhesive to create a curved, integrated backsplash, as opposed to a standard set-on 90 degree backsplash. Normal Backsplash heights are either 3 or 4 inches.
Solid surface materials are susceptible to heat, scratching, and chipping. However; unlike laminate countertops, solid surfacing is repairable. Scratches can be sanded and buffed to give them a like new appearance. We provide matching trivets and cutting boards to ensure the longevity and functionality of your kitchen countertops.
High Pressure Decorative Laminate (HPDL): Our most popular laminate brands are Formica™, Nevamar™, and WilsonArt™
• Today’s laminates have come a long way from their humble beginnings. New patterns, colors, and textures have caused this material to far surpass its previously unremarkable reputation.
• Laminate countertops are the most affordable countertop surfaces on the market today.
• Custom built laminate countertop seams are not joined in corners with 45° cuts as seen in post-formed countertop installations. Joints, if required are placed in less conspicuous places depending on the configuration of the kitchen.
• Custom built laminate countertops do not have rolled or waterfall edges nor coved backsplashes as you would find with post-formed countertops. Edges are squared but can be radiused in most cases to avoid sharp corners. Backsplashes are also squared and are sealed at the joint to the countertop using clear silicone
• Wood edging can be added to custom built laminate countertops. There are a wide variety of edge profiles that can be used. | materials_science |

With this in mind, the passing of Assembly Bill 1884 in California earlier this year was a big win for ocean conservation. Assembly 1884 being the groundbreaking bill that prohibits all full-service restaurants in California from the giving out of plastic straws unless they are requested by the guest. Since the implementation, there have mixed reactions from the public. To combat this we at San Diego Sailing Tours have compiled a list of plastic straw alternatives. From the classic stainless steel straw to silicone and glass straws.
The Silicone Straw
When it comes to traditional plastic straw alternatives our first choice would have to be silicone straws. Many may be under the impression that Silicone and plastic straws are made of the same material. However silicone straws are made of silicon while plastic straws are made up of petroleum, food-grade silicone straws contain no plastic or petroleum. Safe to use and easy to clean silicone straws are a great plastic straw alternative for the whole family.
The Stainless Steel Straw
Along with silicone straws, stainless steel straws are a great alternative to traditional plastic. Stainless steel straws have gained popularity recently for their sleek design and durability. When it comes to cleaning many stainless steel straws come with a pipe cleaner for ease of use. Just make sure to do your research to ensure you purchase the best quality straws that are resistant to rusting and staining.
The Bamboo Straw
If you would like to go for a completely natural plastic staw alternative the bamboo straw is for you! Unlike other alternatives, bamboo straws are typically free of inks, dyes, and bleaches. By using these reusable, biodegradable, plant-based drinking straws you are helping to reduce your environmental footprint one uses at a time.
With so many straw alternatives in the market its easier than ever for everyone to stand up and make a change for a better tomorrow. | materials_science |

The process varies from foundry to foundry, but the steps which are usually used in casting small bronze sculptures in a modern bronze foundry are as follows:
- Sculpting. Master artist, Lyle Johnson creates an original artwork from clay. Oil-based clay is preferred because this material retains its softness.
- Mouldmaking. A mould is made of the original sculpture. Most moulds are at least two pieces, and a shim with keys is placed between the two halves during construction so that the mould can be put back together accurately. To preserve the fine details on the original artwork's surface, there is an inner mould made of latex or silicon rubber, which is supported by the plaster part of the mould. Usually, the original artwork is destroyed during the making and initial deconstruction of the plaster mould. This is because the originals are solid, and do not easily bend as the plaster mould is removed. Often long, thin pieces are cut off of the original and moulded separately. Sometimes, especially in the case of large original (such as life-size) sculptures, many moulds are needed to recreate the original sculpture.
- Wax. Once the plaster and latex mould is finished, molten wax is poured into it and swished around until an even coating, usually about 1/4 inches think, covers the entire inner surface of the mould. This may be done in several layers.
- Removal of wax. This new, hollow wax copy of the original artwork is removed from the mould. The artist may reuse the mould to make more wax copies, but wear and tear on the mould limit their number. For small bronze artworks, a common number of copies today is around 25.
- Chasing. Each hollow wax copy is then "chased": a heated metal tool is used to rub out all the marks which show the "parting line" or "flashing" where the pieces of the mould came together. Wax pieces that were moulded separately can be heated and attached; foundries often use "registration marks" to indicate exactly where they go.
- Spruing. Once the wax copy looks just like the original artwork, it is "sprued" with a treelike structure of wax that will eventually provide paths for molten bronze to flow. The carefully-planned spruing usually begins at the top with a wax "cup," which is attached by wax cylinders to various points on the wax copy.
- Slurry. A "sprued" wax copy is dipped into a ceramic slurry, then into a mixture of powdered clay and sand. This is allowed to dry, and the process is repeated until a half-inch thick or thicker surface covers the entire piece. Only the inside of the cup is not coated, and the cup's flat top serves as the base upon which the piece stands during this process.
- Burnout. The ceramic-coated piece is placed cup-down in a kiln, whose heat hardens the ceramic coatings into a shell, and the wax melts and runs out. The melted wax can recovered and reused, although often it is simply combusted by the burnout process. Now all that remains of the original artwork is the negative space, formerly occupied by the wax, inside the hardened ceramic shell. The feeder and vent tubes and cup are now hollow, also.
- Testing. The ceramic shell is allowed to cool, then is tested to see if water will flow through the feeder and vent tubes as necessary. Cracks or leaks can be patched with thick ceramic paste. To test the thickness, holes can be drilled into the shell, then patched.
- Pouring. The shell is reheated in the kiln to harden the patches, then placed cup-upwards into a tub filled with sand. Bronze is melted in a crucible in a furnace, then poured carefully into the shell. If the shell were not hot, the temperature difference would shatter it. The bronze-filled shells are allowed to cool.
- Release. The shell is hammered or sand-blasted away, releasing the rough bronze. The spruing, which are also faithfully recreated in metal, are cut off, to be reused in another casting.
- Metal-chasing. Just as the wax copies were "chased," the bronze copies are worked until the telltale signs of casting are removed, and the sculptures again look like the original artwork. Pits left by air bubbles in the molten bronze are filled, and the stubs of spuring filed down and polished.
- Patinating. The bronze is colored to the artist's preference, using chemicals applied to heated or cooled metal. This coloring is called patina, and is often green, black, white or brownish to simulate the surfaces of ancient bronze sculptures. (Ancient bronzes gained their patinas from oxidization and other effects of being on Earth for many years.) However, many artists prefer that their bronzes have brighter, paint-like colors. Patinas are generally less opaque than paint, which allows the lustre of the metal to show through. After the patina is applied, a coating of wax is usually applied to protect the surface. Some patinas change color over time because of oxidization, and the wax layer slows this down somewhat.
The lost-wax process can also be used with any material that can burn, melt, or evaporate to leave a mold cavity. Some automobile manufacturers use a lost-foam technique to make engine blocks. The model in this case is made of polystyrene foam, which is then placed into a casting flask, consisting of a cope and drag, which is then filled with casting sand. The foam supports the sand, allowing shapes to be made which would not be possible if the process had to rely on the sand alone to hold its shape. The metal is then poured in, and the heat of the metal vaporizes the foam as the metal enters the mold. | materials_science |

Our warranty is a 7 year replacement pool fabric warranty and surpasses almost every other manufacturer. Just tell us which manufacturer’s pool cover system you have (or describe it to us or send us a picture), and our staff will get you the right cover for your needs.
Our Replacement Pool Covers will work on ANY of the following manufacturers automatic pool cover systems:
Pool Cover Specialists®,
Automatic Pool Covers Inc. (APC or APCI),
Our Fabric is the strongest and most durable Pool Cover Fabric in the industry!
- Our fabric warranty significantly exceeds that of any industry competitor.
- Algae-free fabric means: a cover that cleans easily, and lasts longer.
- Our vinyl is formulated for both chlorine and abrasion resistance.
- Our vinyl is made with virgin PVC resin, BASF Palatinol N plasticizer, and contains no “fillers.” Other coated and laminated vinyl add chalks and other fillers to keep costs down. This is important because other manufacturers vinyl fabrics are subject to significant plasticizer migration, this means that when the plasticizers migrate out of the PVC, the vinyl becomes stiff and brittle. A Pool Cover Specialists® pool cover does not have this problem.
- Our vinyl is “fade resistant” and maintains its luster throughout the life of the fabric.
- The tensile strength is better than the average 18oz coated vinyl available and far superior to any laminated vinyl in the weight range.
- The polyester base fabric is carefully controlled during weaving for straightness, so there is no curving or warping of the finished vinyl.
- Low shrink, non-wicking fibers are used.
Dura Life Fabric is manufactured using a “molten” vinyl manufacturing process so the entire piece of fabric is all one piece and the nylon fibers are completely impregnated with vinyl…NOT separate layers glued (laminated) together like the fabric of other manufacturers. This molten impregnating process Dura Life uses permits the fabric to last longer and not flake apart (layers separate).
Compare Dura Life Fabric to our competitors’ fabric…watch this Video and be AMAZED!

A cone of polymer will form on the outlet of the nozzle referred to as a Taylor cone. A jet of fibre is ejected from the cone which will split into hundreds of fibres in the sub-micron scale. These fibres are then manipulated to form an array of parallel fibres while simultaneously being stretched.
The process is robust and can accommodate most thermoplastics. Produced at room temperature, FibroTend requires no further thermal input. The fibres are streched whilst still in a gel-like state and can be stretched up to 800%.
The fibres produced by an electrospinning process contain a large degree of molecular chain alignment initially due to so called confinement. The polymer chain is further aligned as the fibres progress through the MTL process to form FibroTend.
These fibres exhibit higher tensile modulus compared to non-aligned fibres and results show a two fold increase in value.
FibroTend is produced in a range of fibre orientations from 0 to almost 90 degrees. A multi-layer laminate can be manufactured by overlaying fibres at designed orientations similar to an advanced fibre reinforced composite laminate.
The inherent properties of FibroTend, a highly aligned polymer chain with polarised atoms, exactly match the requirements for making piezoelectric film sensors. We have called this sensor TremoGen as it responds more efficiently to a bending force rather than a compressive force as is the case with ceramic based piezoelectric materials.
The most commonly used polymer for manufacturing piezoelectric film is Polyvinylidene Fluoride (PVDF).
The main requirements for PVDF to gain piezoelectric properties are the polymer chain alignment and the polerisation of the atoms to transform the polymer chain from the α to β phase.
FibroTend achieves these requirements as a matter of course and has enabled MTL to produce piezoelectric PVDF fibres. An array of FibroTend can form a sheet which is then sandwiched between suitable electrodes and over wrapped with a protective flexible and transparent laminate which also helps distribute the bending force uniformly over the entire sensor.
TremoGen is a flexible sensor capable of producing sufficient voltage to be used in many applications such as wearable technology, personal health monitoring devices and as standalone actuators. A typical TremoGen sheet thickness is 200 – 500 nanometres making it ideal for incorporation into textiles or applications that require a high degree of flexibility.
A biaxial FibroTend spun on a low gsm substrate can produce efficient filters. Unlike traditionally spun nanofibres that produce a mat of random fibres and relies on the build up of fibre layers to achieve high filtration efficiency, FibroTend can achieve the same performance through regular pore sizes akin to wire mesh.
The pore size can be regulated for a given particle size so that only one layer of biaxial FibroTend will be sufficient to achieve high filtration efficiency. This will enable thinner filters to be manufactured, minimising pressure drop as well as reducing material usage. These factors will contribute to a lower cost and higher efficiency filtration system.
The FibroTend can be functionalised to be an active filter and due to its inherently large surface area the active ingredients readily interact with contaminates. | materials_science |

"Recycling-oriented design" means designing products from the start to be recyclable, increasing the efficiency of the recycling process.
Chevrolet's recycling-oriented design strategy is an important element of our product responsibility. Our objective is to conserve precious material and energy resources by reducing waste:
- during vehicle production
- at the end of a vehicle’s life
This strategy rests on two principles:
1. Recycling oriented design
All Chevrolet design teams are required to follow "recyclability/recoverability" guidelines during a vehicle's development phase. We aim to support both Chevrolet engineers and suppliers to:
- develop vehicles and components which have recyclability built into them
- analyse parts, components and vehicles in terms of their recyclability and recoverability (the ease with which parts can be recycled at the end of life)
Chevrolet uses recycled materials which are also known as "recyclates" wherever technically feasible and economically viable.
Our recycling team takes every effort to maintain:
- high quality look and feel
- mechanical and thermal durability
- performance standards
Quality is never compromised – The comparable quality of recycled and new materials is so good that they are no longer being restricted to 'hidden parts'. They are used for many visible parts as well.
2. Development and implementation of material "cycles" for vehicle production
The chart below shows how recycling oriented design fits into the overall cycle. Recycling-oriented design forms a key part of our overall integrated product responsibility.
Integrated product responsibility
- Recycling oriented design
- Life cycle assessments

Greenhouse plastic develops a suitable and warm growing environment that allows numerous kinds of plants to cultivate beautifully. It creates an enclosure that secures plants from the damaging ultraviolet rays of the sun while making the most of its natural heat and light. The filtered environment produced by greenhouse plastic makes it possible for garden enthusiasts to grow luscious plants like vegetables and flowers in the cold dead of winter season.
Greenhouse plastic is explicitly created to withstand wear and tear unlike conventional building and construction plastic that can not filter ultraviolet rays from the sun. Greenhouse plastic is long lasting due to its knitted design that permits it to be cut and sized to satisfy the required length for a structure without tearing, ripping or tearing. The material can quickly be framed around any greenhouse opening like a vent, door or windows.
Greenhouse plastic is the preferred covering of most garden lovers compared to other types of greenhouse covering. At the same time expenses are greatly lowered when greenhouse plastic is used given that it lightweight and does not need heavy-duty structural framing. The diffusion of light into a structure built of greenhouse plastic is as good as that of a glass greenhouse.
Types of Greenhouse Plastic
Greenhouse plastic movies are typically made from 3 types of plastics namely, PVC or polyvinyl pe, polyethylene or chloride and copolymers. There are other types of plastic utilized these 3 are most widely used among all.
Polyethylene greenhouse plastic is offered in 2 types, the energy grade and the commercial grade greenhouse plastic. Utility grade polyethylene greenhouse plastic is cost local hardware shops and generally remains in good condition for practically a year. Commercial grade polyethylene greenhouse plastic last longer that utility grade PE approximately eighteen months and is treated with ultraviolet inhibitors that filter out ultraviolet rays.
Innovative additives presented into greenhouse plastic enable it to mimic the very same impacts of a glass greenhouse at significantly reduced expenses. Polyvinyl chloride is more costly compared to polyethylene nevertheless this type of greenhouse plastic can last up to five years.
How to Attach Greenhouse Plastic to Frame
As soon as the frame has been developed it is time to put on the greenhouse plastic movie to enclose the entire structure. Prior to laying the greenhouse plastic covering on the frame it is crucial to mask the joints of the frames with several rounds of tape or a rubber material to avoid it from piercing the covering.
The greenhouse plastic movie can be secured in place using a staple gun. A more rigid building using 1" by 2" wood strips and wood screws can also be utilized to protect the greenhouse plastic movie in location. The wood strips are connected to the frame so that the greenhouse plastic movie does not be available in direct contact with the frame.
Air is introduced into the framed plastics that produce a dead air zone, which can efficiently insulate the whole greenhouse. Different tapes like poly patching tape and batten tape can be utilized to protect greenhouse plastic into location.
Poly patching tape is built from UV safeguarded acrylic together with the adhesive to protect the greenhouse plastic from deteriorating on contact with it. This type of tape can be utilized to patch holes and rips that may take place to the plastic film. Its excellent holding strength and wide tape make an ideal for protecting the plastic movie to the frame of the greenhouse. On the other hand batten tape can be fastened the plastic movie utilizing staples or tacks to the greenhouse structure. It green greenhouse is likewise made of heavy gauge vinyl that is likewise UV secured. | materials_science |

Here’s a great article we found on a Guide to Quartzites. It answers a lot of commonly asked questions about one of our favourite Brazilian stones.
Read the full article, The Definitive Guide to Quartzites by Karin Kirk here.
The Definitive Guide to Quartzite
Quartzite may be the most confusing natural stone out there. A quick internet search will reveal an unsettling disparity of information. Some people say it etches. Some say it doesn’t. Sometimes you hear it’s a hybrid between marble and granite. Yet, others report that it’s harder than granite. Which is it? Why are there such conflicting reports about quartzite?
Let’s use my favourite tool – geology – to suss out the answer to this mystery.
I’ll get right to the point: quartzite is commonly mislabeled. Some quartzite is the real deal, but sometimes marble or dolomitic marble are labelled as quartzite. Because each of these stones behaves differently, people might understandably conclude that quartzite is variable. But it isn’t; quartzite has very consistent properties. Unfortunately, it has variable labelling.

What is quartzite?
Quartzite is a metamorphic rock made almost entirely of the mineral quartz. Quartzite begins its geologic life as sand grains, perhaps on a beach, desert dune, or riverbed. Over time, the sand grains become compressed and stuck together to form sandstone. If the sandstone gets buried ever more deeply underneath layers of rocks, it gets hotter and more compressed. With enough heat and pressure, the sand grains lose their original shape and fuse to their neighbours, forming a dense, durable rock. The process is similar to individual snowflakes merging into solid, glacial ice.
Quartzite is usually white or light-coloured because quartz sand is light coloured. Additional minerals carried by groundwater can impart hues of green, blue, or ion-red. Van Gogh and Azul Macaubas quartzites are examples of vivid colouring.
Regardless of colour, quartzite is made of one thing: quartz. That’s helpful because quartz has distinct properties that make it easy to tell apart from other minerals. (Note I’m talking about the mineral quartz, not the composite countertop material that is also named quartz.)
Properties of quartzite
You needn’t be a geologist to appreciate the hardness and durability of quartzite. Not only does this make for a tough stone, but it also makes it easy to tell quartzite from the imposters. Quartz is 7 on the Mohs hardness scale. That means it’s harder than glass and harder than a knife blade. These things are easy to test with a sample of stone.
If a rock that is labelled as quartzite is soft, then it was mislabeled. The unfortunate term “soft quartzite” has emerged to try to explain why a rock that is labelled quartzite is actually not hard and durable like real quartzite. There is no such thing as soft quartzite though. There is only one kind of quartzite and it’s hard. A rock labelled as soft quartzite is most likely marble.
Resistance to acids
Quartzite will not etch from acids like lemon juice or vinegar. If a rock labelled as quartzite becomes etched from acid, then it’s been mislabeled. Marble and dolomitic marble, on the other hand, will etch from these acids. Dolomitic marble etches slightly more slowly than regular marble. But quartzite will not etch at all from normal kitchen acids. Not one little bit!
Quartzite has a range of porosities. Some, like Taj Mahal or Sea Pearl, have been highly metamorphosed, and the minerals are bonded together tightly. White Macaubas and Calacatta Macaubas have been exposed to less intense pressure, so they are more porous and will benefit from sealing.
Things that do not help distinguish quartzite from non-quartzite
The country of origin, price, or the name of a stone are not reliable indicators of what type of rock you’ve got. In many cases, it’s not even possible to tell marble and quartzite apart visually.
What’s the difference between quartzite and granite?
Granite is a whole separate category of rocks that form from liquid magma. Visually, granite has distinct flecks of darker colours in it, while quartzite has either no dark colours at all or has subtle, flowing areas of different colours.
Sometimes quartzite is mislabeled as granite, which is not the worst mistake because they have similar properties. Granite and quartzite are both harder than glass, and neither will be etched by acids. Geologically, they are different classes of rocks, but that is less important than how they will behave on a countertop or as floor tile.

Enter “Lost Wax Casting,” a fascinating and age-old technique that brings jewelry to life with intricate details and precision. In this blog post, we’ll delve into the captivating world of Lost Wax Casting, exploring the history, process, and intriguing facts that make it a beloved method among jewelry makers.
The Origins of Lost Wax Casting 🕰️
To truly appreciate Lost Wax Casting, we must first step back in time to discover its origins. This remarkable technique dates back over 5,000 years, with its roots in ancient Mesopotamia and Egypt. Archaeological finds have revealed intricate jewelry pieces made using this method, showcasing the enduring legacy of this craft.
Mesopotamian Marvels 🏛️
In ancient Mesopotamia, artisans used wax to create intricate jewelry designs. These wax prototypes were then encased in clay, leaving a hollow space inside. As the clay was heated, the wax melted away, creating a mold into which molten metal was poured. This innovative process allowed for the reproduction of intricate jewelry designs and marked the birth of Lost Wax Casting.
The Lost Wax Casting Process: A Step-by-Step Journey 🌟
Now that we’ve touched on the history, let’s dive into the intricate process of Lost Wax Casting, step by step.

The journey begins with a skilled jeweler crafting a wax model of the desired jewelry piece. This wax prototype is meticulously carved, allowing for the inclusion of intricate details that will later be replicated in metal.
Step 2: Mold Encasement 🏺
Once the wax prototype is complete, it is encased in a heat-resistant material, typically plaster or investment powder. This encasement hardens, creating a durable mold with a cavity mirroring the wax model.
Step 3: Wax Elimination 🕳️
The mold is then heated in a kiln, causing the wax to melt and drip out, leaving behind a hollow space within the mold. Hence the name “Lost Wax Casting.”
Step 4: Metal Pouring 🌋
With the mold now prepared, it’s time for the magic to happen. Molten metal, often gold, silver, or bronze, is poured into the cavity, taking the shape of the original wax prototype.
Step 5: Cooling and Unveiling 🔥
As the metal cools and solidifies within the mold, the jeweler patiently waits. Once the metal has cooled sufficiently, the encasement is broken open, revealing the newly cast jewelry piece.
Step 6: Finishing Touches ✨
The jewelry piece is carefully removed from the mold and undergoes various finishing processes. This may include polishing, gemstone setting, and any additional details required to perfect the piece.
Fascinating Facts About Lost Wax Casting 🤩

They protect walls from dirt, grime, and other potential damage. Businesses use them to create an inviting environment for customers, while homeowners use them to improve the look of their homes. Many wall wraps are available on the market, but they all have one thing in common: They are made of vinyl.
How Are Wall Wraps Made of Vinyl?
Vinyl is a type of plastic that is both durable and flexible. It is made by combining two types of chemicals, polyvinyl chloride (PVC) and vinyl chloride. PVC is a white or light-colored powder combined with vinyl chloride to create the final product.
The manufacturing process begins with the creation of PVC. PVC is made by combining two types of chemicals, ethylene, and chlorine. Ethylene is a gas that is derived from natural gas or petroleum. Chlorine is a gas produced by electrolysis, which uses electricity to split water molecules into their parts: hydrogen and oxygen.
The next step in the manufacturing process is to combine the PVC with vinyl chloride. Vinyl chloride is a gas that is produced by combining chlorine and ethylene. This combination creates a liquid that is combined with PVC to create the final product.
The manufacturing process of vinyl wall wraps is relatively simple. However, it is essential to note that vinyl is a type of plastic. As such, it is not biodegradable and can take up to 1,000 years to degrade. This means that vinyl wall wraps should be disposed of properly to minimize their environmental impact.
How Are Wall Wrap Murals Made?
Wall wrap murals are a type of wall wrap made by printing a design onto a vinyl sheet and then applying it to a wall. Murals can be printed on any type of vinyl, but calendered vinyl is the most common type. Printing a mural onto a vinyl sheet is similar to printing onto paper. However, the vinyl must be fed through the printer in one continuous sheet.
Once the mural is printed, it is cut into sections and applied to the wall. Wall wrap murals can be applied to any wall, but they are most commonly applied to drywall. Applying a wall wrap mural to drywall is a two-step process. First, the mural is applied to the wall with an adhesive. Then, a clear protective laminate is applied over the top of the mural. This laminate protects the mural from damage and ensures that it will last for years.
Are Wall Murals Reusable?
Murals are made of vinyl, which is a very durable material. However, they are not reusable. Once a mural has been applied to a wall, it cannot be removed and reapplied elsewhere. If you want to move your mural to another location, you must purchase a new vinyl sheet and have the mural reprinted.

Furniture is integral to any home; more or less an investment most people make once or twice in their lifetime. That’s why the furniture you purchase should be long-lasting. We, at Customfurnish.com, realize the importance of the durability of furniture and hence, we ensure that the materials used to manufacture the furniture undergo constant quality checks. We are committed to not just provide you with the best quality furniture but we think it is our responsibility to familiarize you with the kind of materials we use so that you can make a well-informed decision about what you want.
Particle board is an engineered or man-made wood manufactured by gluing together the wood chips, shavings, and sometimes sawdust. It is extensively used across the world for manufacturing furniture that is not exposed to humidity and moisture. Particle board that comes with a layer of lamination done on its surface to make it more enduring is known as Pre-laminated board.
Some advantages of using particle board are listed below:
· As long as the lamination does not wear off, the particle board does not warp.
· It does not dent or distort as other soft woods
· It does not expand or contract due to change in weather.
· It bends well due to low weight and density and can be easily used to create long and wide wardrobe doors.
· It is much cheaper than solid wood.
· It is durable in absence of moisture. As moisture can harm the particle board wardrobes, it is not recommended to use it for kitchen furnishings.
· It is portable due to its light weight.
Particle boards are available in varied thickness and density. So, you can basically choose the strength depending on your needs. Also, they are available in wide array of colors that you can choose from.
Medium-density Fiber (MDF)
MDF is an engineered wood made by gluing together the recycled wood fibers by using resin as a binder. High pressure and temperature is applied to form panels of MDF.
The benefits of using MDF are listed as follows:
· It is stronger than particle board.
· It is cheaper than plywood and remains unaffected dues to changes in weather.
· The water resistant variety of MDF does not swell due to moisture and remains intact unlike the solid wood.
· It has a smooth surface without any knots or grains unlike the solid wood. So, it is easier to cut it into various shapes, sizes and designs.
· Its smooth surface also ensures that it is ideal for painting. You can easily paint it to look like real wood.
· MDF is a good substrate for veneering.
Boiling Waterproof Plywood (BWP Plywood)
BWP plywood is an engineered wood, resistant to moisture and high temperature, created from the thin layers of wood glued together at right angles tightly by using Phenol Formaldehyde (PF) resin.
Some of the advantages of using BWP plywood are as follows:
· It is better than solid wood at handling water exposure; thereby making it a popular choice for constructing kitchen cabinets. However, for wardrobes that are not normally exposed to moisture, MDF or Particle board are better choices as they are more cost-effective.
· It is free from termite or borer attacks.
· It is stronger and more durable than MDF or particle board and is lesser prone to warping as the wood is glued together perpendicularly.
· It can be covered with the laminates or veneers that fit your needs.
All three of these engineered woods have their unique benefits and our expert designers utilize them in ways to ensure that our customers get sturdy furniture at affordable prices. We conduct various quality checks at different stages of the manufacturing cycle to check that there is no compromise with the quality of the goods produced. | materials_science |

LIPL Pavers and our concrete masonry products are manufactured under extremely high hydraulic pressure on the world's finest machines equipped with the latest German technology. Manufactured to very accurate dimensions and quality standards, they continue to be popular because of their anti-skid surfaces, ease of laying, durability, time tested design, excellent point load capacities, great visual appeal and extremely low reinstallation and maintenance costs.
ENDLESS ARCHITECTURAL APPLICATIONS & MORE ATTRACTIVE :-
LIPL Pavers, with their highly durable and stable surface, can be used to create interesting design patterns using different sizes, colors, and texture combinations. Pedestrian walkways, residential areas, vehicle parking areas, sidewalks, parks, bus stops, storage yards, loading docks, industrial areas, low speed traffic roads and even heavy traffic areas, are just some of the areas where pavers are used in massive quantities. Unlike asphalt or poured concrete, our concrete paving blocks are available in a variety of shapes and colors, which can create endless number of beautiful patterns and designs to make your outdoors look very attractive
ALL WEATHER PRODUCT :-
In public areas such as parks, swimming pools and pedestrian areas that are frequented by children, LIPL paver blocks are the ideal choice since they tend to remain cooler in the summer season while poured or stamped concrete floorings turn extremely hot when exposed to the sun. The anti-skid surface finish of our pavers makes them the only safe choice you can trust during monsoons when other outdoor flooring options such as thin paving tiles, checkered tiles or glossy rubber mould products become very slippery for pedestrian and cycle or bike movement
EASIEST TO INSALL :-
The installation of our concrete pavers requires neither the specialized equipment nor the intensive skilled labor of asphalt and stamped concrete installations. Interlocking pavers are easy to lay and can be fixed easily in large or small projects by inexpensive equipment and semi-skilled labor. These pavers can also be easily removed and reinstalled later at the same place or elsewhere.
EASILY REUSABLE :-
In the case of required access to underground utilities in a compound, asphalt and poured or stamped concrete have to be broken down to enter. Whereas our paver blocks can be easily removed and reinstalled after repairs are completed giving the end user an advantage of carrying out hassle-free repair and maintenance work.
LESS MAINTENANCE :-
Our concrete paving blocks require far less maintenance than other paving materials such as checkered tiles and other rubber mould products. The strength and durability of concrete paving blocks eliminate costly patching and surfacing.

Thermodynamics and kinetics at the solid-liquid interface can be accelerated by controlling potentials and current intensities, while electrochemistry can simplify purification and post-treatment processes. We focus on the electrochemical synthesis of novel organic electrical materials. A particular emphasis of our philosophy is how to understand the synthesis of electro- and photofunctional polymers from electrochemical approaches. Solid-phase electrosynthesis developed in our group can enable real-time monitoring of redox processes across a variety of length scales while producing complex polymers and materials fabrication. Recent information on our group's current research activities can be found in the group's publications, but a brief introduction to each example of recent projects is provided below.
Keywords: Solid-Phase Electrosynthesis, Iterative Synthesis, Controlled Electropolymerization, Sequence-Controlled Synthesis, Precise Synthesis; Heterometallic supramolecular polymer, Metallopolymer; Polymer Monolayer, Polymer Brush; Nonlinear Conductive Materials and Devices;
(1) Controlled Electropolymerization
Electropolymerization is one of the most important methods for synthesizing and developing conductive polymers. The complexity of the polymerization mechanism, ion doping processes, and structural defects are considered symbiotic and unavoidable, making the stagnant state and huge band gap with advanced interdisciplinary research fields and important applications in the last three decades. We have provided a perspective on controlled electropolymerization by regioselective activation reactions of monomers, where self-dimerization instead of self-electropolymerization was used. The resulting dimers play a role in the connections between functional building blocks to form functional polymers on demand.

(b) Redox dimerizations of electroactive monomers are used to connect the building blocks to form functional polymers. (c) Precise synthesis is conducted by alternative redox reactions via switching positive and negative potentials. Current Opinion in Electrochemistry 2022, 33, 100952. invited review
(2) Solid-Phase Electrosynthesis (Electrochemical Iterative Synthesis, Precise Synthesis)
We developed the electrochemical iterative synthesis of a monomer A-B through individual A–A or B–B coupling driven by electrochemical switching of positive and negative bias on a self-assembled A or B electrode.
Fig. 2 Solid-phase electrosynthesis. Acc. Chem. Res. 2023, in press.
Richly stimulated organometallic polymers are considered candidates for ultra-high information storage and anti-counterfeiting security. However, their controllable synthesis has been an unsolved challenge. We have reported the rapid sequence-controlled electrosynthesis of organometallic polymers with the exquisite insertion of multiple and distinct monomers.

(3) Sequence-Controlled Conductance and Memristive Functions of Metallopolymer Monolayers
Understanding how charge travels through sequence-controlled molecules has been a formidable challenge due to simultaneous requirements in well-controlled synthesis and well-manipulated orientation. We report electrically driven simultaneous synthesis and crystallization as a general strategy to study the conductance of composition and sequence-controlled unioligomer and unipolymer monolayers. Our work demonstrates a promising way to release an ultra-rich variety of electrical parameters and optimize the functions and performances of multilevel resistive devices.

(4) Unidirectional Orientated Non-crystalline Metallopolymers
Long-range ordered nanoarchitecture of polymers is hampered by kinetic and statistical restrictions during polymer synthesis and manipulation. We have reported the monolayer nanoarchitecture of long-range crystalline metallopolymers via kinetically accelerated and statistically allowed iterative growth, guided by a self- assembled monolayer with monitoring and defect-repair abilities.
Fig. 5 Monolayer nanoarchitecture of crystalline metallopolymers by electrochemical iterative growth. Cell Rep. Phys. Sci. 2022, 3, 100852.
Repairable electrosynthesis, combined with the advantages of simultaneous artificial synthesis and manipulation, is a powerful method for fabricating monolayers of unidirectional crystalline functional polymers with sophisticated molecular structures that are very difficult to crystallize. The scalable and programmable electrosynthesis also provides an opportunity to challenge the preparation of an isolated ultra-long polymer and the synthetically iterative limit for further fundamental study.

Elastomeric Roof Coatings
Elastomeric roof coatings are a great option to extend the life of a roof, fix leaks, or increase the energy efficiency of your roof.
Most elastomeric roof coatings last for a minimum of 10 years, are easy to apply, and are much cheaper than a full roof replacement.
Roof coatings are seamless and when installed correctly, can solve roof leaks on almost any type of roof substrate. Field-applied reflective roof coatings can extend the useful life of nearly every roof substrate keeping a roof surface cool and providing a level of protection from the sun and weather.
Roof coatings can add 25 years to the service life of a roof and reduce the amount of discarded roofing materials that end up in landfills. The infrared image on the right shows “175°F” on the uncoated (black) section of the modified bitumen roof. The coated (white) section is “79°F”. Field studies have shown that cool roof coatings can lower rooftop temperatures and reduce air conditioning bills.
TPO (Thermoplastic Polyolefin)
TPO roofing system is one of the latest flat, single ply roofing materials on the market. The current membrane formulations are reinforced with a polyester fabric and manufactured using an ultraviolet-resistant thermoplastic polyolefin formulation. TPO roofing comes in several thicknesses.
TPO can be fully adhered, mechanically fastened, or ballasted. TPO seam strengths are reported to be three to four times higher than EPDM roofing systems. This is a popular choice for environmentally friendly building. It is available in white, grey, and black.
Using white roof material helps increase solar reflectivity and decrease solar heat gain in the building. | materials_science |

(00:48) My name is Ville Valve and I’m the co-founder of VVR Wood. I run the design and development in our company. VVR Wood is a fast-growing timber construction company and we mainly focus on large scale timber constructions.
(01:14) In wood element production, we typically have a lot of different parts and details and most of the work is done off site, so it is essential for us to make sure that every part fits together when it’s finished on the building site.
(01:32) So information management and flow of the information during that process, it’s very important for us. Using wood helps us to reduce the carbon footprint of the buildings. It’s also a very suitable material for off site construction, so it helps us to improve the efficiency and quality of the construction. And also, it’s a natural material that most of the people like to see and feel.
(02:08) Large scale investors and construction companies are trying to find ways to make buildings more environmentally friendly and also they are trying to improve the efficacy of the building processes. Timber element construction is a very viable way of achieving both of these goals. Our production process starts with the architect’s 3D model, and we break walls and slabs to a different element types and then design those elements.
(02:41) And typically our models can have hundreds of different elements and tens of thousands of different parts. And we have to make sure that this information flows through the construction process and is usable in every part of the process.
(03:05) Kerto Ripa is an element type made from LVL using structural gluing. It allows us to make long-span floors and roofs without the use of large beams. This way we can make the elements actually thinner without reducing the capacity of the elements.
(03:31) ArchiFrame is a very important tool for us because we designed everything that we do using ArchiFrame.
(03:58)One of the most important features of our program is the flexibility of the program. In our projects, typically, we have many different types of elements and the construction types are changing in every project. So we have to be able to make different types, different drawing layouts, different parts and the flexibility of ArchiFrame allows us to define the element types by ourselves and change them according to our needs.
(04:30)For us, ArchiFrame is a digital tool and an important part of software automation, which helps our designers to make the routine work faster and more accurate and so they can focus on the most important parts of the building project.
(04:53) In choosing ArchiFrame, one of the most important aspects was the strong integration with Archicad. It’s software which is used in a lot of architectural designers’ offices and this allows us to work more closely with the architects and also we don’t have to give other designers so many restrictions and guides to be able to integrate in our design processes.
(05:31) Every project is different. We have to be able to meet our customers’ needs. | materials_science |

Quality Standard Picture Frame Mouldings
We have selected only the best wholesalers to supply our framing materials and mouldings.
We regularly use high quality synthetic mouldings manufactured from compressed polystyrene , Wooden mouldings are manufactured and finished locally from obeche wood. The obeche wood is imported from West Africa and grown sustainably.
High quality synthetic mouldings have replaced many wooden profiles over the last few years. Synthetic mouldings are suitable for high moisture content areas such as bathrooms and homes at the coast.
For most applications it shouldn't matter if you choose wood or synthetic.
Both will do the job perfectly.
Wood mouldings are still as popular as ever before. The raw and natural profiles are currently the most sought after for a contemporary gallery look.
Most of our wood mouldings are made from a species of wood called Triplochiton scleroxylon, commonly known as Wawa, specially imported from plantations in West Africa conforming to sustainable resource harvesting.
Sustainable harvesting is a main priority for our suppliers when searching for new wood suppliers. They have to carry an FSC certification that proves that their forests are sustainably harvested.
Aluminium mouldings are manufactured and finished in South Africa.
New aluminium profiles are very narrow and can acheive what wood can't.
Here are links to our selected suppliers.
Supreme Mouldings - Best known for quality Synthetic Mouldings
Serame Mouldings - Best known for quality Wooden Mouldings
Print Design and Mouldings - Best known for quality Aluminium profiles
Quality Standard Framing Materials
We use only the best quality framing materials and finishes.
Our standard backing board is 3mm MDF. Consider the final picture frame as a sandwich of materials all working together to protect and support your artworks. New synthetic mouldings are not as rigid as wooden mouldings. An inferior backing compromises the integrity of the entire structure. Some framers use inferior cardboard box materials. Some are even using used boxes from the local supermarket. These materials have a high acid content, they warp and absorb a lot of moisture. This becomes the perfect place for mould spores to develop and migrate into you art or photographs.
Our standard clear glass is 3mm thick. Some framers are using 2mm glass on very large artworks. We have replaced the broken glass on many artworks where the glass has broken and sliced through valuable artworks.
As an alternative we also use 3mm Clear Acrylic (Perspex) and we can source 2mm and 4mm museum glass. These are the most expensive options and take a lot longer to complete.
Quality Standard Accessories
We use only high quality framing accessories.
Mostly from the AMS brand.
Art Materials Service has been manufacturing high quality, reliable framing accessories since 1976.
We have packaged smaller quantities for your convenience.
We also offer self adhesive brown paper backing tape, double sided tape, cotton gloves and acid free archival framers tape. | materials_science |

A good wooden terrace perfectly complements any back yard, but for the deck to look good for a long time, it needs to be tended regularly – impregnated, painted every couple of years, and it must be regularly cleaned from moss. This is a laborious and expensive process, especially if you are not willing to do it yourself and need to hire workers to do it for you. Therefore, for practical and economical reasons, long-lasting outdoor decking made of wood and polymer composite (WPC) is becoming increasingly popular. WPC decking boards are widely used in outdoor cafes as well as backyard garden terraces, balconies, pool flooring and boat docks.
Manufactured in Latvia - with reverence for nature
"WPC GreenDECK" Ltd. is a company that draws knowledge and experience from abroad to manufactures high quality decking boards with the brand name "GreenDECK" right here in Latvia, Aizkraukle. Over the years, the company has developed an optimal approach to decking board production. GreenDECK decking boards are particularly suitable for the changing climate of our region, as they are made from local Baltic softwood timber, which is highly resistant due to the constant climate changes – long winter and short summer periods. A high-quality, raw and impurity-free polyethylene is included in the composition of GreenDECK decking boards, making them extremely durable. It should be emphasized that no trees are cut down for the production of GreenDECK decking boards. Wood fibers used in manufacturing are raw materials, carefully collected from carpentry factories and recycled for the production of GreenDECK decking.
Eco friendly and sustainable
Forget painting and impregnation
GreenDECK decking production process uses extrusion technology. Decking boards are produced under high temperature and high pressure conditions, and they consist of 60% natural wood fibers and 40% eco-friendly polymer. Wood fibers give GreenDECK decking boards the natural texture of wood, while the polymer confers longevity and durability, as well as making the material easy to take care of. In contrast to wooden boards, GreenDECK decking boards do not need to be impregnated, painted or oiled. It is sufficient to occasionally wash the boards with water. GreenDECK decking is highly resistant to moisture and the harmful effects of exposure to sunlight. They are also resistant to fungal and insect exposure. In general, GreenDECK decking boards have more than ten years of dependable service warranty without using any additional protection. | materials_science |

We have just started stocking these wonderful stainless steel hoop earring findings (after many requests!). They are so easy to use (just pull out the wire from the crimp attachment at the top), and slide on your beads! They even have a little hole if you would like to dangle a bead in the middle… which of course we did 😀 In this design, we have used some of our lovely new Pyrite beads and Golden Obsidian beads. We think they make for a striking combo! We’ve made a couple of different design – see at the bottom for something slightly different. These earrings took next to no time to make – the hardest part is cutting that hard stainless steel wire (tips below!). Of course the possible combinations of colours and shapes are endless for these earrings – the only limitation is the curve of the hoop – so beads with a long (straight) hole will not go on.
These earrings are made with 100% Stainless Steel findings. Stainless steel has the benefits of being hypoallergenic, extremely strong and hard wearing, and is resistant to tarnishing. Stainless Steel is a darker colour than silver, and looks more like our nickel silver products.
Beads and Materials You’ll Need:
- 2x 8mm faceted round gemstone bead (we’ve used Golden Obsidian)
- 4x 6mm faceted round gemstone bead (we’ve used Golden Obsidian)
- 2x Larger flat bead for dangle, 14mm to 18mm works well (we’ve used Pyrite Discs 16mm*)
- *Please note, as with all of our fancy gemstone beads and pendants, we change our stock regularly – so if these beads are no longer available, try something different!
- 11/0 Seed Beads (we’ve used Metallic Grey Seed Beads)
- 10x Stainless Steel Rondelle Spacer Beads
- 2x Stainless Steel Earring Hoops
- 2x Stainless Steel Earwires
- 2x Stainless Steel Headpins
Tools You’ll Need:
Step 1. Pull out the wire from one side of the earring hoop.
Step 2. Simply thread on your beads! We’ve used 9 seed beads either side of the gemstone beads (so 18 seed beads per earring). And we’ve used a stainless steel rondelle spacer between each gemstone bead. Then insert the wire back into the connector at the top.
Note: If you would like the earring to be totally secure, you can now go ahead and crimp the side of the connector that you just inserted the wire into (use very fine needle nose pliers). Be careful not to push the wire in too far, as if you cover the small hole with your wire you will not be able to attach your dangle. However, crimping the connector is not really necessary – the wire itself is a memory wire, and the tension will hold the wire in place.
Step 3. Now it’s time to make the dangle. Take your headpin, and slide on your Pyrite Disc bead. Add a stainless steel rondelle spacer. Measure about 1cm above this bead and prepare to cut. And here’s the tricky part – normal pliers will struggle to cut through stainless steel headpins (and will likely get quite damaged in trying to do so). In fact, even my memory wire cutters ended up just ‘smooshing’ the wire and bending it, and wouldn’t cut through.
The technique that ended up working best for me was using a very cheap pair of cutters (or an old damaged pair) to mark the pin where I wanted to cut. I marked it a couple of times at the same position above the bead, just moving the pliers around the wire. Then I gently bent the wire back and forth until the wire snapped at that point.
Step 4. Using round nose pliers, form a loop in your headpin.
Step 5. Attach the open loop to the small hole on the earring hoop connector. Close the loop with your flat nose pliers.
Step 6. Now simply attach your earwire. Because these earwires have a ball on the loop at the bottom, you’ll have to thread them onto the hoop from the other end of the earwire.
Step 7. Close the gap in your earwire using flat nose pliers.
And you’re done!

ASTM Level 2 masks provide moderate barrier protection for low to moderate levels of aerosols, spray and or fluids. ASTM Level 3 masks provide maximum barrier protection and are used for high risk of fluid, spray or aerosol exposure.
How to put on an ASTM Level 3 Mask:
1. Clean your hands with soap and water or hand sanitizer before touching the Mask.
2. Take the ASTM Level 3 Mask out of the box or packaging and make sure there are no obvious tears or holes in either side of the Medical Mask.
3. Determine which side of the Face Mask is the top. The side of the Mask Level 3 that has a stiff bendable edge is the top and is meant to mold to the shape of your nose.
4. Determine which side of the Mask is the front.
5. Hold the Mask by the ear loops and place a loop around each ear.
Do not touch the Medical Face Mask once in position.
If the ASTM Level 3 Face Mask gets soiled or damp, dispose it properly and replace it with a new one. | materials_science |

About Gas Springs
Are your gas springs going out on your boat hatches? Are you tired of your boat hatches falling down? You need to get the industry leading gas spring hardware for your hatches. Attwood gas springs come in three different styles: Ni-Slide (the SL series), Boost Series (the SH series), and Stainless Steel (the ST series). Let's look at each of these:
- Ni-Slide Gas Springs- the standard product line with the widest range size offering. The shafts are carbon steel and Nitrogen case hardened to enhance the performance and life of the product. The cylinders are black powder coated. This being the standard line it is the most affordable of the three series. It can be used in a range of applications and depending on the actual exposure to the environment can be used in saltwater applications but not recommended if it is presented to constant exposure to the saltwater elements. The end fittings are composite with traditional metal spring clips to retain the socket onto the ball pen.
- Boost Series Gas Springs- is a unique gas spring because of the fact that the product is designed with a stainless steel shaft and carbon steel cylinder body that is clear coated for corrosion resistance. This is obviously a step up from the SL series due to it's enhanced salt spray protection. The fact that it is not 100% stainless steel allows us to serve the industry with a cost contained product that will stand the rigors of the saltwater environment. The sockets are a 100% composite design and won't rust due to a uniquely designed release system that eliminates the need for the metal spring clip
- Stainless Steel Gas Springs- these products are 100% stainless and use the 100% composite sockets. These are for the boaters that want the protection of a fully constructed stainless spring. | materials_science |

Industry News, Products, Tips & Tricks,
It is not uncommon for individual cells in the batteries to heat up, start to burn and thus cause other cells to burn. The fire can then no longer be stopped, and extinguishing it with water no longer works. You have to wait until the battery has burned down completely.
The company Dolav developed a transport box in which batteries can be transported safely and which also withstands the conditions that occur in the event of a fire. We now want to take a closer look at this transport box.
So the idea of creating a way to withstand the stresses of a battery fire was obvious.
So Dolav, together with experienced scientists, created AkkuGrain®, an interactive granulate that only becomes active when it is needed due to heat generation or the release of acidic, alkaline or other hazardous substances.
In the event of thermal runaway (overheating of a battery cell by a self-reinforcing heat-producing process), the fleece of the AkkuGrain® bags melts and the granulate spreads in the plastic box. The heat generation releases water vapour, which is bound as water in the AkkuGrain® granulate in its crystallised state.
The Thermal Runaway is not extinguished, but cooled down considerably. While temperatures of 1000°C can easily be reached in a battery fire, AkkuGrain® cools the Thermal Runaway down to about 340°C to prevent the fire from spreading further inside or outside the box. This strong cooling down has the effect that the temperature on the outside of the plastic box is only about 25°C.
The oxygen content inside the box is reduced to 8%, so there is no longer a risk of explosion. Toxic gases that are produced when the battery burns down are filtered and remain below the legally defined limit of the EU when emitted. Another advantage is that the AkkuGrain® can be reused as often as desired after transport without thermal runaway. However, damaged fleece bags caused by sharp objects must be replaced.
AkkuGrain® Bag [S] (500 x 300 mm)
AkkuGrain® Bag [M] (500 x 600 mm)
AkkuGrain® Bag [L] (600 x 1000 mm)
The plastic box is available in various standard sizes, such as the Euro pallet size or, at 3 metres by 2 metres, the largest plastic box. Together with their partner DryFireCon, a container was developed that can even accommodate electric cars, whose fire can also be contained by the AkkuGrain® in the event of a thermal runaway. | materials_science |

Unbreakable and stretchable screens are always been in the news. So, what do you think? An unbreakable screen would be a reality?
Recently, a group of Japanese researchers has found a way to make a screen that can heal itself. Basically, researchers have found a new type of material that is similar to glass, but, it can regenerate itself in case of damages.
The material discovered by researchers is known as ‘Polyether-thioureas’. The group of researchers has published detail reports regarding Polyether-thioureas in the Journal Science.
According to the reports from The Guardian, a big thanks goes to Yu Yanagisawa, a student at the University of Tokyo, who is also a team member of the study, was preparing a material to use it as a natural glue and he realized that all the broken pieces of glass were gathered together.
Moreover, the material also conducts electricity, so it would be ideal for use in electronic devices like smartphones and tablets. The Polyether thiourea can heal itself when the broken pieces are pressed together and having pressure applied to it.
So far we have just seen self-healing material that can heal itself from minor scratches. However, the new material seems that it works with completely broken pieces. Just imagine, your phone screen shatters into pieces and pressing it together will fix it.
So, the project looks pretty cool, right? However, there is still no final date fixed for this new material to avail in the market. | materials_science |

The analysis of hydrogen peroxide (H2O2) holds significant importance in a wide range of fields. H2O2 serves as a commonly employed oxidizing agent, making it an essential mediator in the realms of biology, food, medicine, industry, and the environment.1-2 Methods such as chemiluminescence,3 fluorescence,4 spectrophotometry,5 and electrochemical techniques have been reported for the accurate detection of H2O2 concentration. The accuracy of the detection of H2O2 has been increased with the development of detection techniques for each area, and the electrochemical sensors in particular play more important roles because they have operational simplicity, low cost, high sensitivity, and suitability for real-time detection.6
Here, Prussian blue (PB) having an open, zeolite-like structure is well known as the prototype of polynuclear transition-metal hexacyanometalates.7 Due to the structure of PB, large molecules cannot penetrate into the lattice whereas small molecules such as H2O2 can be.8 PB exhibits electrochemical,9-10 electrochromic,11-12 photophysical,13 and magnetic properties.14-15 In particular, the electrocatalytic property of PB enables the potential development of electrochemical sensors using the PB-modified electrode.16-17 Consequently, the pursuit of a reliable H2O2 detection method using PB complexes as catalysts has gained significant attention.18-20
To improve the sensitivity and stability of PB-based electrochemical sensors, several methods have been suggested to synthesize PB nanoparticles (PBNPs) over a range of sizes and shapes by chemical processes such as reverse micelles,24 ionic liquids,25-26 mesoporous silicate,27 and polymer beads as mediums or templates.28 Furthermore, the synthesis of PBNPs using functionalized organic polymers has been widely studied. These polymers provide the chemical and spatial environment, allowing for the stable construction of particles. They also help to form a colloid and prevent the solution from aggregation.29-31 Research on conductive polymers has continued owing to their excellent physicochemical properties resulting from their unique π-conjugated system32 which provides a powerful platform for sensing applications and a variety of functions from the polymers.
Poly(p-phenylenediamine) (PpPD) is one of the most studied multifunctional poly-arylamines owing to the characteristics of the enhanced redox activity by the presence of amino groups in its chain of PpPD. Because of the low conductivity of PpPD, the use of a conductive inorganic material such as carbon nanotubes,33 noble metals,34 or nanoparticles35 has been studied to make PpPD available for electrolysis or electrochemical sensors. In particular, multi-walled carbon nanotubes (MWCNTs) which are composed of π-conjugated networks, have high electrical conductivity, excellent thermal stability, and large surface area, and thus the advantage of easy functionalization or the manipulation of their surface properties.36-37
In this study, MWCNTs coated with PpPD conductive polymer based on the PBNPs were proposed for the development of an electrochemical H2O2 sensor. The MWCNTs@PpPD was synthesized by simply coating PpPD on MWCNTs and used to form the PBNPs with PB precursors in an acidic solution. The composite maintained good electrical conductivity even wrapped PpPD on MWCNTs and formed stable PBNPs to the strong electrical catalyst for H2O2. This system displayed suitable linear range, low detection limit, and high sensitivity. In addition, it showed high selectivity to ignore interfering species such as ascorbic acid, uric acid, and L-cysteine.
Multi-walled carbon nanotubes (MWCNTs, 95% purity, diameter 10–15 nm) were purchased from ILJIN Nanotech Co. (Korea). L-cysteine was purchased from Yakuri Pure Chemical Co. (Japan). Ammonium persulfate ((NH4)2S2O8, APS, ≥98.0%), p-phenylenediamine (C6H8N2, pPD, ≥99.0%), potassium ferricyanide (K3Fe(CN)6, 99+%), potassium ferrocyanide (K4Fe(CN)6, 99%), iron(III) chloride (FeCl3, 97%), potassium chloride (KCl), acetic acid (99.7 wt% in H2O), hydrogen peroxide (H2O2, 30 wt% in H2O), Nafion (~5% in a mixture of lower aliphatic alcohols and water), ascorbic acid, uric acid, and glucose were purchased from Sigma-Aldrich Co. (USA). All the chemicals were used without further purification. All the solutions were prepared with deionized water (DIW) obtained from an ultra-pure water purification system (Human Co., Korea) with a resistivity of not less than 18.2 MΩ cm. All the measurements were carried out at room temperature.
The surface morphology of composites was characterized by field emission transmission electron microscopy (FE-TEM, JEOL JEM-F200, Japan). TEM samples were prepared by placing a drop of the dispersion on a carbon-coated copper grid. Fourier transform infrared spectra (FT-IR) analyses were performed using a Perkin-Elmer Spectrum 2000 FT-IR spectrometer in the range from 400 to 4000 cm-1 with a KBr pellet. Powder X-ray diffraction (XRD) analyses were performed using a New D8 advance diffractometer. Electrochemical impedance spectroscopy (EIS) measurements were performed using a CHI 760B electrochemical analyzer (CH Instrument, Inc., USA), and cyclic voltammetry (CV) and amperometry were performed using a CHI 842B electrochemical analyzer (CH Instrument, Inc., USA) with the conventional three-electrode system. A bare or modified glassy carbon electrode (GCE, d = 3.0 mm) was used as the working electrode. A platinum (Pt) electrode served as the auxiliary electrode, and a silver/silver chloride (Ag/AgCl) electrode filled with 3 M KCl served as the reference electrode. All ultrasonic cleaning was performed using a US-2510 Ultrasonic Cleaner (Branson, USA). Before each electrochemical measurement, solutions were thoroughly deoxygenated by bubbling N2 gas through the solution for at least 10 min to remove the dissolved oxygen.
2.0 mg of Pristine MWCNTs were added to 17.6 mL of DIW and well dispersed by a 30 min sonication. To this solution, 2.0 mL of 0.1 M pPD and 0.4 mL of 0.1 M APS were added at room temperature under vigorous magnetic stirring for 24 hours. The dark purple solution was carefully filtered through a membrane filter and washed with DIW. The collected precipitate was dried overnight in an oven at 40℃. Finally, the product was dispersed in an acidic solution at pH 3.5.
1 mM of K3Fe(CN)6 was added to 25 mL of 0.1 M KCl solution and adjusted to pH 2.7. To this solution, 0.8 mL of dispersed MWCNTs@PpPD solution was added under magnetic stirring for 5 min. 25 mL of 1 mM FeCl3 was added slowly to this mixture with continuous stirring at room temperature for 1 hour. Subsequently, 2 μL of 30% H2O2 was added to the mixed solution. The color of this solution gradually changed from yellowish green to dark blue. After 3 hours, the obtained dispersion was filtered, rinsed with DIW several times, and finally redispersed in 10 mL of DIW.
Before modification, the glassy carbon electrode was polished to acquire a mirror-like surface with fine alumina powders (particle size: 0.3 μm and 0.05 μm) on a polishing pad. The electrode was cleaned and sonicated with DIW for 2 min, in sequence. After drying under a gentle stream of N2 gas, the modified electrode was prepared by dropping 8 μL of the MWCNTs@PpPD-PB dispersion onto the purified GCE surface and dried in an oven at 40℃ for 2 hours. Then, 2 μL of Nafion (0.5%) was placed on the surface of the modified electrode, and it was dried again in an oven at 40℃ for 1 hour.
Fig. 1 shows the synthetic route for MWCMT@PpPD-PB. At first, pristine MWCNTs were dispersed in a neutral solution through sonication. pPD monomers were added to the solution, and APS was further added resulting in a dark-violet solution. And then, the solution containing MWCNTs@PpPD nanocomposite was added to an acidic solution containing K3Fe(CN)6, and FeCl3 was dripped very slowly. The snapshots of the products for each step are shown in Fig. S1.
Fig. 2 shows the XRD patterns and FE-TEM images of MWCNTs, MWCNTs@PpPD, and MWCNT@PpPD which suggests the morphologies and sizes of the as-synthesized nanocomposites. The peaks centered at 2θ values of 26.0° and 43.0° correspond to the (002) and (100) reflection planes of graphite from the MWCNTs, respectively.38 The diffraction pattern of the MWCNTs@PpPD nanofibers shows five big sharp peaks (marked as asterisk marks) and eight minor peaks between 2θ = 8-30°.39
Compared to the XRD pattern of the MWCNTs@PpPD, the peaks of MWCNTs@PpPD-PB are observed at 2θ values of 17.5°, 24.8°, 35.3°, 39.6° and 43.7° correspond to the (200), (220), (400), (420), and (422) reflection planes, respectively.40 All the reflections can be indexed as a pure face-centered-cubic phase of Fe4[Fe(CN)6]3, which demonstrates the successful synthesis of PB on the modified MWCNTs. Furthermore, the average diameter of the PBNPs was ~15.4 nm, calculated by the Scherrer formula.41 It is analogous to the diameter of the PBNPs of MWCNTs@PpPD nanocomposite determined from the TEM images, which were measured at 10.2-17.5 nm.
Fig. S2 shows the FT-IR spectra of MWCNTs, MWCNTs @PpPD, and MWCNTs@PpPD-PB which investigate the chemical components of the as-synthesized samples. After the polymerization of pPD on the surface of MWCNTs, the characteristic absorption peaks of PpPD were observed. The broad absorption peaks located at 3444 cm-1 and the shoulder peak located at 3216 cm-1 could be because of the N–H stretching vibration of the –NH group in MWCNTs @PpPD. Furthermore, in another broad adsorption peak assigned approximately from 1650 to 1300 cm-1, the two strong peaks located at 1606 and 1545 cm-1 can be attributed to the C=N and C=C stretching vibration of the phenazine ring structure, respectively.42 The other peak located at 1494 cm-1 corresponds to the stretching of the benzene ring. The two small peaks at 1262 and 1208 cm-1 are assigned to the imine C=N stretching vibration of the benzoid and quinoid imine units (–C=N–)42, proving that PpPD was successfully polymerized on MWCNTs. Compared to the MWCNTs@PpPD, the MWCNTs@PpPD-PB nanocomposite showed a strong absorption peak at 2083 cm-1 which is attributed to the C≡N stretching absorption band in the [Fe2+–CN–Fe3+] structure of PB. An absorption peak at 502 cm-1 was also observed, because of the formation of [Fe2+–CN–Fe3+] structure.
The inset in Fig. 3 is the Randles equivalent circuit model used for fitting the measurement data, where Rs for electrolyte resistance, Cdl for double-layer capacitance, Rct for electron transfer resistance, and Zw for Warburg impedance. Rct represents the electron-transfer-limited process at the electrode/electrolyte interface and is equal to the semicircle diameter in the Nyquist diagrams. It is measured in a background solution, containing 5 mM [Fe(CN)6]3- and 5 mM [Fe(CN)6]4- in 0.1 M KCl at the frequency range from 10 mHz to 100 kHz at 0.19 V (vs. Ag/AgCl).
Fig. 3 shows the impedance spectra represented as the Nyquist plots (Z′ vs Z") for (a) bare GCE, (b) GCE/PB, (c) GCE/MWCNTs, (d) GCE/MWCNTs@PpPD, and (e) GCE/MWCNTs@PpPD-PB. Rct of the bare GCE was 127.14 Ω with an almost straight tail line. When MWCNTs were cast on the GCE, Rct decreased to 42.66 Ω, indicating that the MWCNTs could prompt the charge transfer. Furthermore, when the GCE electrode surface was coated with PBNPs, Rct value increased considerably to 421.79 Ω, indicating that the PBNPs on the GCE obstructed the charge transfer of the electrochemical process at the electrode surface. After the MWCNTs@PpPD was dropped over the GCE, the diameter of the high-frequency semicircle was significantly reduced to 9.06 Ω as a Rct value. Rct value of MWCNTs@PpPD-PB was 42.43 Ω, which is greater than that of the MWCNTs@PpPD, indicating that PB interrupted the charge transfer. Note that GCE/MWCNTs@PpPD-PB showed a steeper Warburg slope at low-frequency limit compared to others. This is due to the increased significance of chargetransfer resistance and double-layer capacitance as the frequency rises.43
Fig. 4(a) shows the CVs of the bare GCE, GCE/MWCNTs, GCE/MWCNTs@PpPD GCE/MWCNTs-PB, and GCE/MWCNTs@PpPD-PB in the absence of H2O2. The redox peaks were observed in the CVs of MWCNTs-PB and MWCNTs@PpPD-PB modified GCE, whereas no redox pair peaks were observed for the bare GCE, GCE/MWCNTs and GCE/MWCNTs@PpPD. Between the observed redox peaks, the peak current of MWCNTs@PpPD-PB modified GCE was much larger than that of MWCNTs-PB modified GCE, probably because of the high electrical conductivity of the coated pPD polymer on the MWCNTs. After adding 5 mM H2O2, the CVs of the bare GCE, GCE/MWCNTs, and GCE/MWCNTs@PpPD did not change (Fig. 4(b)). Meanwhile, the CVs of the MWCNTs-PB and MWCNTs @PpPD-PB modified GCE show that the reduction peak significantly increased, but the oxidation peak decreased slightly. These results indicate the presence of PBNPs on the modified GCE.
Fig. 5 shows the CVs of GCE/MWCNTs-PB and GCE/MWCNTs@PpPD-PB in N2-saturated 0.1 M KCl (pH 2.7) at different concentrations of H2O2. The cathodic peak current value increases with the increasing concentration of H2O2 because of the PB. Moreover, Fig. S3 shows that the reduction current of the MWCNTs@PpPD-PB-modified GCE is about twice as high as that of the MWCNTs-PB-modified GCE.
Fig. 6 shows the correlation between the current and the scan rate. The electrochemical effect of the scan rate on the electrocatalytic H2O2 cathodic current was investigated to evaluate the kinetics of the electrochemical performance of the as-synthesized MWCNTs nanocomposites. The cathodic peak currents increased linearly in proportion to the square root of the scan rate with a correlation coefficient of 0.9978 as the scan rate was increased from 10 to 200 mV/s (Fig. S4). This result signifies that the process of electrocatalytic reaction is diffusion-controlled.
Fig. 7 shows the comparative amperometric response of GCE/MWCNTs-PB and GCE/MWCNTs@PpPD-PB for successive sensing of H2O2 into stirred N2-saturated 0.1 M KCl (pH 2.7) aqueous solution at an applied potential of +0.15 V (vs. Ag/AgCl). The reduction current value showed a rapid response to the subsequent addition of H2O2 and quickly reached the 95% steady-state current, which was less than 2 sec. In the MWCNTs-PB modified GCE and the MWCNTs@PpPD-PB modified GCE, the current for both increased with the addition of H2O2, and cathodic current of the latter was greater than the former.
The amperometric response was unstable with the addition of H2O2 probably because of the weak interaction between the MWCNTs and the PBNPs. To solve this problem, the MWCNTs were effectively coated by PpPD and strongly attached to the PBNPs. Therefore, the modified electrode composed of the MWCNTs, PpPD, and PB showed a better response to the addition of H2O2.
Fig. S5 shows the calibration curve of the reduction peak currents versus the concentration of H2O2, which presents the linear response region of MWCNTs-PB and MWCNTs @PpPD-PB. MWCNTs@PpPD-PB shows a linear response range from 0.005 mM to 2.225 mM with a correlation coefficient of 0.9992, and the sensitivity of the sensor was 583.6 μAmM-1cm-2, which was much higher than that of a previous study estimated from GCE/MWCNTs-PB and GCE/MWCNTs/Ppy/PB.44-45 Moreover, the limit of detection of GCE/MWCNTs@PpPD-PB was calculated as 0.95 μM with a signal-to-noise ratio of 3.
Table 1 summarizes the electrochemical characteristics of various modified electrodes containing PB for sensing H2O2, indicating that GCE/MWCNTs@PpPD-PB has a high sensitivity and a wide linear range in comparison to those of other reported modified electrodes, proving improved electrical conductivity and good stability.

An amperometric measurement was performed to assess the selectivity of the as-synthesized sensor. Fig. 8 shows that the current generated in the presence of 0.1 mM of interfering substances, such as citric acid, ascorbic acid, and L-cysteine. These interfering substances could be ignored relative to the current attributed solely to 0.1 mM H2O2 in N2-saturated 0.1 M KCl solution (pH 2.7) at an applied potential of 0.15 V, indicating that this sensor possessed an excellent anti-interference capacity.
The reproducibility was investigated by the CV experiments on five modified electrodes under the same condition, showing excellent performance as evidenced by a relative standard deviation (R.S.D) of 2.5%. Fig. S6 shows the stability examined by monitoring the current response in 1 mM H2O2 solution after effectively cycling the modified electrode. After 50 cycles, the reduction of the electrode signal was only 2.6%, and after 50 additional cycles, the loss of signal reached only 2.9%. To determine the life span of the prepared sensor, the as-synthesized electrodes were stored in a refrigerator at 4℃, and the electrode signal decreased to only 97.1% of its original peak current in 1 mM H2O2 after 20 days. In brief, MWCNTs@PpPD-PB on the GCE showed excellent selectivity, reproducibility, and stability. The current response becomes stable in less than 2 sec, which indicates the rapid response of the MWCNTs@PpPD-PB on the GCE towards H2O2.
The performance of MWCNTs@PpPD-PB nanocomposites on the GCE was analyzed by applying it to the determination of H2O2 present in the household disinfectant. Using amperometry measurement to obtain the response of the household disinfectant, the experiment was conducted under the same conditions as the conventional amperometry experimental conditions. The exact H2O2 concentration in the household disinfectant was measured using the standard addition method.
The concentrations obtained by stepwise increasing the concentration and the R.S.D are listed in Table 2. The recoveries of H2O2 were found to be in the range of 95-100%, indicating that the modified electrode is suitable for real sample analyses.
In this study, an approach for simple fabrication of sensitive electrochemical detection of H2O2 was described based on MWCNTs@PpPD-PB nanocomposites. The MWCNTs@PpPD was easily synthesized without structural destruction of MWCNTs by PpPD coating. PpPD not only serves to ensure good dispersion of MWCNTs in the water but also increased the reduction currents of H2O2. This modified electrode showed a good electrocatalytic response for reduction of H2O2 in an acidic solution and showed good linear range, high sensitivity, low detection limit, good reproducibility, and better stability. Finally, MWCNTs @PpPD-PB modified glassy carbon electrode was applied successfully to detect H2O2 in real samples as a sensor.

Understanding the primary and secondary post-processing stages and their best practices is essential for achieving optimal results.
Primary Post-Processing – Cleaning:
The primary post-processing stage involves removing excess unfused material from the printed part’s surface, crucial for preserving the part’s look, feel, and dimensional accuracy.
Techniques for Primary Post-Processing:
- Bead Blasting: This involves propelling glass beads at high pressure against the part’s surface. Bead blasting provides a uniform “satin” finish and does not affect the part’s dimensional stability. Both manual and automatic bead blasting systems are used, with the latter allowing for simultaneous processing of multiple parts.
- Air Blasting: Often used in combination with bead blasting, air blasting involves propelling a stream of compressed air onto the part’s surface. It helps remove any remaining powder material and blast media dust.
- Water Jet Blasting: This technique uses a fluid mixture of compressed air and water to remove powder. It is especially effective for cleaning complex geometries or ducts and can slightly reduce surface roughness.
Considerations for Bead Blasting:
- Blast Media: Glass beads (70–110 µm diameter) are recommended for MJF parts. They ensure no dimensional accuracy alteration and provide a more uniform surface.
- Air Pressure: Adjust air pressure based on the blasting system (manual or automatic) and the part’s fragility.
- Nozzle Diameter and Distance: The nozzle diameter and distance to the part significantly impact the cleaning effectiveness.
Water Jet Blasting Advantages:
- Complex Geometries Cleaning: Ideal for intricate parts due to different nozzle orientations.
- Reduced Surface Roughness: Can achieve smoother finishes compared to traditional vibratory systems.
- Dust-Free Environment: Eliminates the need for subsequent processing to remove blast media dust.
Secondary Post-Processing: Cosmetic and Surface Roughness Reduction:
Secondary post-processing includes techniques that provide cosmetic attributes or reduce surface roughness. These include dyeing, painting, vibratory tumbling, and chemical polishing.
Key Factors in Secondary Post-Processing:
- Dyeing and Painting: These methods can enhance the part’s visual appeal but may impact dimensional accuracy.
- Surface Roughness Reduction: Techniques like vibratory tumbling or chemical polishing improve the part’s tactile feel and appearance.

Tooth Restorations for All Cases
Crowns and Bridges are amongst one of the most common dental fixtures required all over the world. At Astro Dental Art, we have a wide variety of Crowns & Bridges to suit both your budget and your aesthetic needs.
All-Ceramic Crowns & Bridges
All-Ceramic crowns and bridges are cosmetic dental restorations that are designed to either cap or completely cover a tooth that is being restored. It is the most natural-looking tooth replacement.
Types of All-Ceramic Crowns & Bridges
The Zirconia Solid all-ceramic crowns & bridges are monolithic and made purely from zirconia, and 100% metal-free.
The Zirconia HT is are highly translucent all-ceramic crowns & bridges that are much stronger than PFM products.
The Zirconia Layered all-ceramic crowns & bridges are extremely strong and designed for multi-unit bridges where the IPS e.max® is not suitable.
With versatility, reliability and longevity in mind, e.max® is unmatched in clinical success. With biocompatible lithium disilicate ingots, e.max® offers optimized esthetic properties, creating restorations that offer true-to-natural results.
The ultimate in metal-free esthetics and durability for both anterior and posterior applications. Provides unmatched strength (400 MPa flexural strength). Indicated for single-unit crowns and 3-unit anterior bridge cases (from 2nd bi-cuspid forward).
Etching & Silanization
Etching & Silanization is the process of creating an appropriate surface to bond the IPS e.max®. It is important as it helps the IPS e.max® attach to teeth more securely and therefore allows the IPS e.max® to have a longer lifespan. Astro Dental Art provides Etching and Silanization service for our clients. Call us at (403) 455-0300 for more information or to book an appointment.
Process of Etching & Silanization
STEP 1 – Buffered Hydrofluoric Acid Gel
Bisco’s Porcelain Etchant improves the adhesive bond between porcelain and cement by increasing the surface area of the porcelain to be bonded. The effect is similar to sandblasting but is more controlled and effective. Porcelain Etchant will microscopically roughen the feldspathic porcelain or glass surface. Bisco’s Porcelain Etchant is available in 2 concentrations: 4% or 9.5% (Hydrofluoric Acid Gel).
STEP 2 – 37% Phosphoric Acid Etchant with Benzalkonium Chloride
Etch-37 w/BAC is a 37% phosphoric acid semi-gel etchant that is effective at quickly etching enamel and dentin. Etch-37 w/BAC is polymer-thickened and effectively removes the smear layer, etches and demineralizes enamel and dentin. It is easily manipulated into small areas such as endodontically treated root canals and undercuts. This makes it more versatile than some thicker gel etchants for etching all restorative surfaces. Published research proves that Bisco etchants produce higher bond strengths to (wet or dry) dentin1 and enamel.
- Rinses away cleanly and quickly leaving no residue to interfere with bonding
- Blue in color for easy visualization and contrast
- Creates microretentive surface characteristics that are necessary for successful bonding.
- New bulk syringe delivery system available
- Contains benzalkonium chloride (BAC), an antimicrobial agent. In-vitro research shows it is effective against Actinomyces viscosus.
STEP 3 – Bis-Saline
A two-part Silane coupling agent offering additional shelf-life stability to ensure long lasting effective bonding to porcelain.
Minimal Prep Veneers – Feldspathic veneers have been made popular by patients for their non-invasive preparation requirements, and their ability to allow the existing tooth shades to shine through.
This hand-crafted veneer is created with artistry by use of a brush and glass-based powder mixed with liquid. This material is highly translucent and mimics natural dentition when applied properly. To fabricate feldspathic veneers, the technician hand paints the veneer layer by layer so contour and texture can be controlled and crafted. Then the veneer is baked on a foil tray to solidify. The results are a highly esthetic restoration that is ideal for anterior restorations where shape, texture, and natural-beauty are priorities.
Porcelain Fused Metal Dental Crowns (PFM)
PFM combines the strength of a metal coping with hand layered porcelain. The metal base gives off a natural-like hue from within that is complimented when porcelain is applied.
A PFM crown has been known to leave the appearance of a dark line at the gums in some cases, and because of the core being comprised of metal, sometimes the quality of the metal is not up to standard. Thankfully you now have a choice of what type of PFM crown you would like to order. We can use standard metals, noble metals, or high noble metals which are precious alloys. It’s even possible now to combine the benefits of a metal structure with the digital technology of milling the base of the crown in a digital milling machine.
Types of PFM Dental Crowns
The White Hi-Noble PFM dental crowns have a lifespan of over 30 years if properly maintained with good oral hygiene practices.
The Yellow Hi-Noble PFM dental crowns are made with precious metal and have a lifespan of over 30 years.
The Semi-Precious PFM dental crowns are strong and durable and therefore have good marginal integrity.
The Non-Precious PFM dental crowns are strong, versatile, and durable and have a lifespan of over 60 years.
Full Cast Crowns & Bridges
Full Cast Crowns and Bridges have the potential to last a lifetime due to its durability. The restorations done on full cast crowns and bridges are often designed to fit perfectly, as the materials used offer great bio-compatibility, as well as are known to be extremely compatible with the human mouth (except in the case of alloy sensitivity).
Types of Full Cast Crowns & Bridge
The Semi-Precious full cast crown & bridge has characteristics that allows for long-term wear. With good oral hygiene, they can last for 30-40 years.
The Gold full cast crown & bridge is one of the most wear-friendly of dental materials of all time. It is extremely bio-compatible. | materials_science |

We’ve developed the #160 for sharpening very dull blades, and re-profiling bevels to a lower angle.
If you often repair dents, reprofile bevels, or do first-time sharpening for knifemakers, you will benefit to add the extra coarse #80 wheel to your inventory aswell for quick steel removal.
We recommend 2-3 strokes on each side of the knife on the #160 wheel after working with #80 grit.
It is also perfectly possible to grind on the side of the wheel if a completely flat grinding phase is desired.
Our CBN wheels can be run with common running water from your house or workshop tap thanks to the special embedding technology. Note that if you run CBN wheels of other makers with water, the CBN coating may detach from their wheel base.
Cubic boron nitride (CBN) properties include extreme hardness, stability under heat, and superior chemical resistance.
Cubic boron nitride is the second-hardest known material on the planet (after diamonds), but has higher heat and impact resistance than diamonds, and therefore CBN is preferred over diamond in industrial applications. | materials_science |

Soldering is a thermal process for the bonded joining of materials. With the help of a soldering iron or laser, the required heat is provided for solid soldered joints and for melting the solder. This allows various components and materials – such as those made of nickel, copper, metal, steel, iron and aluminum – to be bonded together. A metal alloy that melts easily (called the solder) serves as the bonding material for the soldered joint. Soldering process equipment includes an automatic, programmable solder feeder and a variety of sensors for process monitoring. One special application is soldering in a vacuum or shielding gas. These processes are used to ensure that stringent cleanliness requirements are met, e.g. for semiconductor assembly or in the production of high vacuum systems or electron tubes.
Distinction between two different soldering technologies:
- In soft-soldering, the melting point of the solder is below a temperature of 450 °C – for example, in the electronics industry.
- In hard-soldering, or brazing, the melting point of the solder is above a temperature of 450 °C – for example, for particularly strong joints in the automotive industry or in the photovoltaic and battery sectors. | materials_science |

Low rolling resistance, outstanding safety and durability are the three main requirements that car tyres need to fulfil, both today and in the future. To drive progress in this area, the scientists and engineers at Sumitomo Rubber Industries Ltd. conducted pioneering research into the molecular structure of tyres, using particle accelerators and advanced simulation computers. They succeeded in simulating and controlling the molecular structure of rubber compounds used for tyres at nano level; for example, they analysed where and how superfluous heat was generated in the tyre and how this development could be minimised. Heat means loss of energy for the tyre, and thus rolling resistance – which is ultimately responsible for fuel consumption. Advanced 4D-Nano Design technology is the result of these advanced findings in molecular structures. It enables savings in fuel consumption of up to five per cent to be achieved compared to conventional tyre models, and significantly improves the tyre’s performance in wet conditions. | materials_science |

These types of roofing tiles are ideal for people looking for a tough and environmentally friendly roofing option.
A clay roof is a great choice if you want to limit the amount of maintenance that you will have to perform. The reason for this is that clay roofing tiles are going to be able to last a lifetime, and are often more than capable of lasting much longer than the house they are installed on. In many cases, your clay roofing tiles will last for at least 100 years.
Another reason that clay roofing is a great choice for someone who wants a strong and durable roof is that clay is one of the most fire-resistant roofing materials available. This makes clay roofing tiles one of the best choices if you live in a very dry area where there is a risk of fire. In those areas, a fire that breaks out in your neighborhood will not be able to spread to your house as easily because the sparks and embers that a fire uses to spread from roof to roof will not be able to ignite your clay roofing tiles.
In addition, clay tiles are not at risk in wet climates where insects and moisture can destroy many other roofing materials. Clay roofing tiles do not have any materials that will cause rot, and insects are unable to bore into or eat the clay tiles.
Clay roofing tiles are also a great choice if you want to limit your home's energy usage and make your home more environmentally friendly. This is possible in the summer because the clay tiles will reflect light rather than absorb it. When a roof absorbs sunlight, your home heats up and will often lead to you using your air conditioner more often.
Another way that clay roofing tiles can keep your home cool is because of their shape. The shape of clay tiles allows air to flow above and below the tiles, which creates an additional insulating barrier that traps cool air in the home and keeps hot air out. In addition, this insulating barrier can help you keep your heating bills down by preventing cold air from entering the home and warm air from escaping.
Speak to a roofing contractor today in order to discuss whether clay tiles are right for your home. Clay tiles are a fantastic option that is both tough and great for the environment.Share | materials_science |

The print color is limited to black, unless special, preprinted direct thermal paper is used. The printing is not as crisp as that of thermal transfer ribbon printing, and over time the labels will darken. The main benefit is an overall lower cost, since ribbon is not required.
Thermal transfer barcode label printers require the use of a carbon ribbon which gets transferred onto the substrate via heat. The ribbons can be different colors, so you are not limited to printing only in black. The printing is very crisp and durable so this method is excellent for high density bar-codes and labels that require longevity. The other benefit is that thermal transfer printers can print on paper, film, and even foil substrates. | materials_science |

The Plasmafit PRO Shell with Vitelene Liner Acetabular System is a two-piece system containing a metal shell and plastic liner. The system has been designed to provide long-term implant survivorship and offer a high-level of implant performance.
The Plasmafit PRO shell is inserted into the acetabulum of the hip and the Vitelene liner is inserted into the shell. The femoral head that is placed onto the hip stem engages the liner which recreate the ball and socket movement of the hip joint.
Plasmafit PRO Shell with Vitelene Liner offer the following benefits to patients:
Implant Long-Term Survivorship – The Plasmafit PRO shell design, along with the applied rough coating, combine to encourage the bone to fixate to the implant for long-term stability.
High Performance – The Vitelene liner is made from polyethylene blended with Vitamin E. The polyethylene liner is subject to oxidation in the body. Oxidation can degrade the material, causing it to weaken. Vitamin E is a naturally occurring antioxidant substance that has been introduced into the liner to help ensure the process of oxidation is limited, thereby reducing the potential for degradation and maintaining the performance of the material for long-term use. The liner is then permitted to maintain as a smooth, hard material that can absorb the impact and stress from daily activities like walking and sitting to running and playing sports. | materials_science |

Launched in 1949 on the premise of “pushing recycling in the design industry” by turning industrial textile waste into premium rugs, all of the brand’s products now contain 68 per cent waste material.
“Recycling is woven into everything we do,” Bolon told Dezeen. “In just a few years we have gone from 28 per cent recycled material to 68 per cent by doing what we have always done: we saw potential in waste.”
The family-owned brand’s manufacturing takes place in a “climate-neutral” factory in Ulricehamn, Sweden, which means that any carbon emissions produced are offset.
Rather than have a “green collection”, Bolon has instead pledged to ensure all of its products are climate-neutral too.
“In 2020 we set an ambitious goal to halve our climate impact and ensure that all our products contain at least 50 per cent recycled material by 2028,” said the brand.
“This year, we’ll surpass our goal substantially and will be able to offer 68 per cent recycled material in all our products.”
Some of Bolon’s recent material innovations include bio-sourced PVC made from pulp and paper industry waste, recycled PVC and recycled chalk derived from marble slab production.
“In 75 years, Bolon has evolved from humble beginnings to a global leader in design-led, sustainable flooring solutions, with renowned clients across the world,” said the brand.
Aesthetics are also important to the company, with prominent names such as Patricia Urquiola and Jean Nouvel all creating collections with Bolon over the years.
The brand says its ultimate goal is to “turn waste materials into beautiful flooring and rugs of supreme quality”.
Bolon products previously featured on Dezeen include a muted made-to-measure rug collection designed for high-footfall commercial interiors and Bolon Studio, a collection of woven flooring in bold geometric prints that can be customised by users.
The company, which says it is committed “to never standing still”, is also considering a number of future initiatives.
“We are currently looking into developing a take-back [scheme] for used flooring and rugs,” said Bolon.
“We are also going to continue our journey to replace virgin materials with recycled or bio-sourced materials.”
“We believe in creating new dimensions by challenging conventions and breaking down barriers,” it added. “We are dreamers and innovators and see that in the future we will be able to offer woven design to more than just flooring and rugs.”

But recent developments in roofing material can now help prevent this type of damage from occurring in the first place. Known as “impact resistant,” a new type of single can make your home’s roof nearly impervious to most hail- and wind-related damage. The question is: are they worth the cost? We’ll find out in this impact resistant shingles review.
What are Impact Resistant Shingles?
Shingles that are “impact resistant” are considered a class 4 product, and are designed to withstand high winds and hail damage. These shingles may be made of copper, aluminum, resin and plastic.
Shingles with the Class 4 rating have an impact resistance rating of UL 2218. The UL 2218 is the roofing industry standard for testing shingles against hail impact. There are four testing classes that use four different steel ball sizes that range from 1 1/4” to 2”. These steel balls are dropped at heights between 12 and 20 feet to mimic the impact of hail falling at high speeds.
The UL 2218 is currently the highest impact resistance rating. Aside from hail impact, these shingles can also withstand high winds up to 110mph.
Are Class 4 Impact Resistant Shingles Worth the Cost?
Generally, yes. But it really depends on where you live. Thousands of homeowners lose their roofs to wind and hail damage each year, but some areas are more affected by damaging storms than others. Homes in areas that experience stronger, damaging storms will benefit greatly from impact resistant shingles because they offer long-term roof protection.
Impact resistant shingles do cost more initially, but they pay for themselves in the long run. Typically, these shingles cost 10-20% more than their non-impact counterparts. That being said, they reduce a homeowner’s maintenance costs and may even prevent premature roof replacement.
Many insurers also offer discounts to homeowners with a Class 4 roof. This discount can also help offset the higher costs of these shingles. | materials_science |

with additives in
Potassium Nitrate/Sugar Formulations
The melt viscosity of propellant formulations based on potassium nitrate and sugars can be dramatically lowered with the use of certain surfactants at low levels. However, the burn rate, under pressure, of many of these propellants containing surfactant is often significantly effected. Most often burn rates are significantly longer at chamber pressures lower than ~700 psi. Traditional Bates 2 grain 38mm motors using KNO3/sugar propellants at (65:35) with 3/8” cores with no surfactant present have burn times between 0.75 and 1.13 seconds according to Nakka’s SRM simulation spread sheets (for sucrose, dextrose, and sorbitol using Aerotech type hardware at 1000 psi max chamber pressure). Personal test stand evaluations gave burn times of ~ 1.7 seconds and Isp engine ratings between 125 and 128 sec in two separate motor burns using sorbitol fuel. This indicates that my personal test stand is generating data that match that modeled by Nakka. It is interesting to note that motor burn times of ~1.7 sec for sorbitol based motors matches those burn times I obtain for high pressure surfactant containing sorbitol motors as well as those sorbitol/surfactant motors using RIO as an additive.
The links below, based on the different sugars used as fuel, connect to pages with data on the use of surfactants such as Polystep B-1 with this basic 65:35 formulation. Links are also present which will detail experiments using other surfactants that exhibit viscosity reduction (other_surfactants). Test stand evaluation of other additives used as burn rate modifiers in combination with surfactant have their own page as well. Although fine Al and Ti powders are really considered fuels rather than additives, links to test stand data on motors with these metals are also present (other_additives). The use of other additives such as RIO in formulations containing surfactant does not affect the viscosity reducing ability of the surfactant. The presence of such an additive does, however, negate the unusual lengthening of the burn rate sometimes seen with some formulations which contain only a viscosity reducing surfactant as an additive.
Test stand results comparing formulations with and without surfactant reveal that sometimes slight reductions in Isp occur and at other times normal normal motor performance is obtained when surfactant is present. When it occurs this reduction appears to be on the order of 5 - 10%. Work is ongoing to determine what variable(s) cause this ISP reduction or why it sometimes does not happen. Most likely this difference is due to increased "flushing" as described on the Nakka web site (http://www.nakka-rocketry.net/knsbchar.html). | materials_science |

A novel method for preparing samples for use in MALDI-TOFMS (matrix-assisted laser desorption ionization time-of-flight mass spectrometry) is described. Seven hydrolysis products derived from nitrogen mustards and CHCA (α-cyano-4-hydroxycinnamic acid) were selected as model compounds and the matrix, respectively. A capillary atomizer was used for evaporative and spray deposition of the sample/matrix solution, leading to the formation of a freestanding film that coated and accumulated on the MALDI substrate (i.e., sample plate). Compared to the traditional method for MALDI, which involves the production of dried droplets, the surface roughness was reduced, resulting in the accumulation of the sample-doped matrix on the sample plate. This resulted in an increase in the limit of detection of 1 − 2 orders of magnitude. In order to compare the structures of the sample-doped matrices obtained by the traditional dried droplet method versus the spray deposition method (developed in this study), the matrices were examined by SEM (scanning electron microscopy). The design of the capillary atomizer and details of the experimental conditions are reported. The application of this method to the above seven degradation products was successful, suggesting that it has great potential for use as a routine monitoring tool. | materials_science |

The simplest type of aesthetic filling is what people commonly refer to as "bonding". This filling is performed by the dentist in one single sitting and is comprised of a composite resin material (a mixture of glass and resin particles) that is placed into smaller cavities and bonded or adhered to the tooth chemically with special liquid “bonding agents”.
The second type of aesthetic filling is the ceramic inlay or onlay (partial coverage restoration). They are made in our own laboratory, from a high density porcelain-like material that is baked under vacuum pressure in a special Ivoclar Empress processing machine. Ceramic fillings are some of the most aesthetic restorations that modern dentistry can offer. They are strong, natural looking and long lasting. | materials_science |

Tri-State Rigging Equipment is an authorized Rigging Weld and Service Center. With over 60 years in the material handling industry, we are experts at manufacturing and repairing rigging slings of all types. These include:
- Chain Slings
- Wire Rope Slings
- Polyester and Nylon Synthetic Slings—round or web style
- Fiber Rope Slings
- Metal Mesh Slings
In addition to crane slings we can also take care of all your sling protection needs from corner guards to wear pads to sling sleeves. If you are unable to locate what you need, here at Tri-State we can custom configure and manufacture a sling to fit any application.
If you need help finding what you are looking for, call or email our sales team to speak with a rigging product specialist.
Chain rigging slings are constructed using the industry standard grade 80 and grade 100 alloy steel chain. Chain slings are popular in overhead lifting due to their ruggedness, strength, resistance to abrasion and cutting, and their ability to perform under exposure to high temperatures. This allows alloy chain slings to be used in:
- Steel Mills
- Heavy Machine Shops, etc.
Chain lifting slings are made from alloy steel and can be custom configured to fit any lifting or rigging application. Chain slings are easily modified and repaired offering industry leading versatility. Lifting chain slings are available in single-leg, 2-leg, 3-leg and 4-leg alloy chain bridle assemblies and they can be used in vertical, choker, or basket hitches. In addition, chain slings can be configured to have adjustable leg lengths. Adjustable chain slings are an ideal solution for picking up asymmetrical loads and loads with an unknown or awkward center of gravity.
Wire Rope Slings
Wire rope rigging slings, sometimes referred to as cable lifting slings, consist of individual steel wires that form strands, the strands are then laid around a fiber or steel IWRC (Independent Wire Rope Core) core. Wire rope can be manufactured in a wide variety of patterns and constructions. These patterns and constructions all give the wire rope different properties, allowing wire rope slings and bridles to be used in variety of different working conditions and applications. Wire rope lifting slings are overall more cost-effective and lighter in weight than similar capacity chain rigging slings. This makes them very popular in the following industries:
- Oil and Gas
- General Manufacturing
In addition to these industries, wire rope bridles and assemblies can stand up to the harsh conditions seen in steel mills and forging facilities. Steel wire rope slings are available in single-leg, 2-leg, 3-leg, and 4-leg wire rope bridle assemblies. In addition, they can be used in vertical, choker, and basket hitches.
Synthetic rigging Slings can be broken up into three subcategories, all offering different benefits and drawbacks:
- Synthetic Round Slings
- Synthetic Web Slings
- Synthetic Rope Slings
Synthetic lifting slings can be constructed of either nylon or polyester, with each material offering different properties and benefits. Synthetic rigging slings lead the industry in combined strength, flexibility and support. Synthetic lifting slings are perfect for situations where it is imperative that the load not be damaged by the sling.
Synthetic slings can be configured to fit almost any rigging application. This includes single-leg, 2-leg, 3-leg, and 4-leg synthetic bridle assemblies. Additionally, they can be used in vertical, choker and basket hitches. Due to their ease of use, relative inexpensiveness, standard sizes and replaceability, they are very popular in construction and other general industries.
Metal Wire Mesh Slings
Metal mesh lifting slings, sometimes referred to as wire mesh slings or chain mesh slings are constructed using high-tensile carbon, alloy, or stainless-steel links, arranged in a tightly knit mesh pattern. Wire mesh rigging slings are extremely abrasion and cutting resistant and can also withstand the high temperatures seen in the metal working industry as well as many others. Metal mesh slings are especially useful for securing and lifting unusual or irregular loads due to their wide bearing surface. While they are not quite as versatile as other types of slings, they can be used in vertical, choker and basket hitches.
The leading cause of lifting sling failure, especially in the case of synthetic slings, is cutting and abrasion. Often, in order to get a secure grip on the load, the rigging sling must be wrapped around sharp and/or protruding edges. This puts undue stress on the sling, no matter the type, and can significantly reduce not only your sling's durability but also your sling's WLL (working load limit). Sling protectors like edge guards, wear pads and sling protector sleeves, come in a variety of different shapes, styles and materials but they are all used to lessen the amount of cutting and abrasion forces exerted by a load on whatever sling you decide to use.
Best Rigging Practices
- Crane slings are to be hitched in a manner that provides optimal control of the load
- Sharp edges or protruding edges in contact with a sling are to be padded with material of sufficient strength to protect the crane sling
- Crane slings are to be shortened or adjusted only by methods approved by the sling manufacturer or a qualified person
- When any crane sling is off the ground personnel should be alert for possible snagging. Especially when the sling is empty as it is more prone to snag things it passes by when not lifting a load
- In a basket hitch, the load must be balanced to prevent slippage
- Keep loads in a basket hitch under control by ensuring that the legs of the rigging sling contain or support the load from the sides, above the center of gravity
- In a choker hitch, make sure the choke point is on the crane sling body only, and not on a fitting
- In a choker hitch, angles of choke less than 120° are not to be used without a reduction in the rated load
- Ensure that lifting slings are not constricted, bunched, or pinched by the load, hook, or any fitting
- The load applied to the hook should always be centered in the base of the hook to prevent point loading on the hook, unless the hook is designed for point loading
- Never shorten or lengthen a crane lifting sling by knotting or twisting
- Never rest loads on the rigging sling
- Never pull a rigging sling from under a load when the load is resting on the sling
- Never drag crane slings on the floor or over abrasive surfaces
- Shock loading is never acceptable and can significantly damage your rigging sling
- Always avoid twisting and kinking
Tri-State Rigging Equipment is a custom manufacturer, service provider and distributor for all crane lifting slings serving clients from coast to coast, Canada, Mexico and especially focused in the states of Missouri, Illinois, Indiana, Iowa, Kansas, Nebraska, Arkansas, Mississippi, Tennessee, Kentucky, South Carolina, Florida, and Oklahoma. | materials_science |

This is true for all tungsten jewelry in the world. Ion plating is a process by which a surface is bombarded with atomic sized energetic particles in a vacuum to deposit a hard coating of compound materials that results in a desirable color. The process is vastly superior to traditional "wet" plating methods (like electroplating) due to its increased bonding strength.
Ion plating, while more difficult to scratch than traditional gold or silver, is not as scratch resistant as the underlying tungsten. Plating can be damaged through contact with an abrasive surface or substance, chemicals, and hard surfaces (metal, wood, tile, etc). Plating can also be damaged by frequent exposure to hard water, or repeated contact with moderately hard surfaces such as a computer mouse or the inside of a glove.
For these reasons, we recommend removing plated tungsten rings before doing such activities as: handling metal objects, going to the gym, playing sports, entering water, and washing dishes or hands. We understand that this can seem like an inconvenience, but it is no different than wearing a traditional gold or silver ring. Rings such as these should be treated with attentive care.
If you are interested in a black band, we recommend looking into black ceramic as opposed to black tungsten. Ceramic is nearly just as strong a material as tungsten but the color is not plated so it does not have this issue. This is why you will see that many of the black rings that we offer are made from ceramic. Ceramic is also very lightweight compared to tungsten carbide.
In terms of hardness, tungsten carbide is rated at 9 on the Mohs scale while ceramic is 7 (diamond is a 10 and gold is 3 to give a sense of scale). Essentially what this means is that they are both very strong. Both rings can be cut in case of emergencies and hospitals will have the equipment to do so. Neither ring will fade, though the ion plating on black tungsten can be worn as we mentioned earlier. The hardness of the plating is 6, the same strength as titanium. Theoretically black tungsten can be replated and ceramic can be refinished, however we don’t have the equipment to do so and there is basically no need to do so, ever. Neither can be resized in the traditional sense, however we do offer a lifetime resizing guarantee if you ever do need a different size down the line. We also have a lifetime guarantee that covers almost everything except for normal wear and tear or intentional damage.
If there’s anything to be aware of, it’s that our warranty does not cover normal wear and tear, including scratches. While our rings are highly durable and scratch-resistant, they are not scratch-proof. Nothing is. Even a hard diamond can be cut. If you like some heft with your ring, you may want black tungsten. Both rings will be difficult to scratch, but black plated tungsten may show the silver tungsten underneath while black ceramic will just show black ceramic. Side by side, black tungsten will look slightly more black, while black ceramic will have a slightly dark gray tint to it just because it is more reflective. | materials_science |

Prepreg is a dielectric material that is sandwiched between two cores or between a core and a copper foil in a PCB, to provide the required insulation. You can call it a binding material as well. It either binds two cores or a core and a copper foil.
If you can imagine a hamburger, prepreg is the slice of cheese placed between the bread and the ham. The bread and ham can either be a core or a copper foil. Now I am sure I got your attention.
I would like to tell you something interesting about prepregs. Prepregs are special dielectric materials that can be modified to our needs. By the combination of certain additives and catalysts, under a chemical process, a specific section of a prepreg can be transformed into a conductive region. This is called selective conductivity. This phenomenon finds its purpose while drilling holes into the prepregs for connecting the top and the bottom layers. However, the rest of the part of the prepreg remains to be an insulator and protects the circuit board from short circuit which is its basic functionality.
Years of immense research and development have been undergone for the selection of the right prepreg material. Factors like thermal and mechanical compatibility of a material must be considered to accommodate the PCB requirements.
How are prepregs made?
Prepreg, as the name suggests, is a glass fibre weave/cloth impregnated with a resin bonding agent. The glass fibres are interwoven to form a glass fabric. This glass fibre weave is partially dried to form a B-stage material. All prepregs are B-stage materials. During the manufacturing process of prepreg, it is important to follow the grain direction of the material being used since it allows the material to be modified as per requirement. The number of warp and fill counts determine the amount of resin the glass fabric can retain.
There are different types of prepregs that are incorporated in PCBs depending on the thickness and other requirements. Prepregs are available in Standard Resin (SR), Medium Resin (MR), and High Resin (HR) depending on the resin content they hold. The more resin content they hold, the more expensive they get. Here’s a table for your better understanding:
The difference between Prepreg and Core
People often get confused between prepregs and cores due to their similarities. Allow me to clarify it for you. The core is a product of prepreg and lamination. It is more rigid compared to the prepreg. The core is made up of a fiberglass-epoxy laminate which meets the FR4 (Flame Retardant) grade with copper on either side. The core is usually manufactured by a core manufacturer and the company is liable for any faults in the material that might hinder the operation of a PCB. Whereas prepregs, as described earlier, are also made of the same material like the core but are partially dried without lamination and aren’t rigid like the core. I hope this disposes of the ambiguity.
Now, the thickness of the PCB depends on the type of prepregs used. It must be noted that the required thickness can be achieved by a combination of prepreg plies. If you are wondering what plies are, they are nothing but thin sheets of prepregs placed on top of one another. This helps in achieving the desired thickness of the PCB.
Other than PCBs, prepregs find their applications in aerospace components, automotive parts, A/C ducting, machinery, tooling, honeycomb and foam panels, and many more.
In conclusion, prepregs are insulators that glue together cores and copper foils and assist in the manufacture of a robust PCB.

Pro-tec by WIX oil filters hold more than 45 Percent more dirt than the leading national brand. We could stop here, but we’re sure you want to know why. Oil filter effectiveness is measured three ways: particle size retention (filtration efficiency), dirt-holding capacity, and resistance to flow. WIX has developed optimum particle size retention quality in filter media through extensive engine wear tests in the real world, at the race track and in the lab. In fact, WIX media in automotive full-flow oil filters traps and holds essentially all particles larger than 25 Microns (a human hair is roughly 70 Microns in diameter), while capturing a high Percentage of even smaller particles. The dirt-holding capacity of WIX filters is significantly larger than the minimum manufacturer requirements between oil changes, which provides you with added security that contaminants captured by the filter stay in the filter. All WIX full-flow oil filters for automotive and light truck applications use arch-pleated, prescription-blended media, which provides low initial restriction to oil flow – less than 2 PSI pressure drop when filtering oil at a rate of 4 Gallons Per Minute at normal operating temperatures.

The particle analysis on hydraulic fluid used to test the produces items, showed that the contamination was mostly composed by small metal particles not coming from the tested items. Starting from this point, we tried to find out the origin of this contamination and we discovered that quite all this particles come from a procedure of sandblasting which pump and motor housing went through. Even if this parts, after this procedure, went through a washing procedure, they come out uncleaned. Checking the washing machine, we found that it was highly contaminated by the same particles found on the housings. The filtration system of the washing machine, was designed to block only big sized particles, with 80-100 microns rating filter medias. Smallest particles were able to pass this filters and remain in the system.
We choose to modify the washing machine filtration system, replacing housings and using new 10 microns elements. In this way the problem was solved. | materials_science |

Solidification. Chemical Fixation. Chemical Oxidation.
The following treatment technologies typically offer significant savings when compared to off-site treatment and disposal. They offer economical treatment methodologies for treating heavy metals, solid organics, PCBs, and other waste streams.
Stabilization techniques limit the solubility or mobility of contaminants. To accomplish this, reagents or other specialized materials are blended with the soil and/or sludge. Stabilization ensures that the hazardous constituents are suspended in their least mobile or toxic form.
Solidification results in a solid, low-permeable block of contaminated soil. To accomplish this, reagents are utilized to mechanically lock the contaminants within the solidified matrix. This process significantly decreases contaminant migration.
This technology achieves the destruction of contaminants and creates non-hazardous materials. Similar to stabilization and solidification, chemical fixation requires the blending of reagents with the contaminated material. The reagents used during the mixing/blending process effect destruction or chemical bonding of the contaminant(s).
In-situ chemical oxidation (ISCO) is a cost-effective and viable remediation technology for the treatment of petroleum-based contaminants and VOCs in soils, sediments, and groundwater. Once a representative sample has been analyzed and the chemicals of concern are identified, bench testing is performed in order to determine the type and quantity of reagent to employ. | materials_science |
