The film growth in the low coverage regime at 110K, the influence of the different iron oxide surfaces on the phase transition of amorphous grown ice to crystalline ice as well as the adsorption behaviour under isobaric conditions at room temperature were of great interest. Beside these, experiments were carried out to investigate the photo chemical properties of these three different adsorbate systems. The water adsorption at 110K shows a different adsorption behaviour on all three iron oxides. A detailed adsorption model could be developed for water on Fe3O4(111). First step is the dissociation of the first adsorbing molecules. Additional water coverage leads to the formation of dimers. On top of these dimers following water molecules form the first 3D-ice structures. Further more it could be shown, that the different iron oxide surfaces influence the phase transition of amorphous ice to crystalline ice differently. Based on an existing equation, a new equation was created, that not only describes the ideal phase transition on surfaces with little or no effects on the adsorbed ice layer but also the phase transition on surfaces with strong effects due to structural and charge properties. With the isobaric adsorption measurements, it could be shown that the presence of Oxygen (g) influences the adsorption of water on Fe3O4(111) and Fe2O3biphase strongly.

### Title: ['Crystallisation of semiconductive oxides from borate glasses']
### Abstract:
['A preparation method was developed in order to obtain undoped and doped In2O3 and SnO2 nanopowders through controlled crystallisation of borate glasses and subsequent dissolution of the matrix in acetic acid. The nano-powders have been separated through dissolution of the additionally formed non In-containing crystalline phases and the glassy phase, and then subsequently dialysed.

### Title: ['Global optimization with unknown Lipschitz constant']
### Abstract:
['We study the global optimization problem, i.e., for a real-valued and bounded function f we are interested in a point x of the domain whose function value f(x) is close to the infimum inf f. We consider the case that f is d-variate, Lipschitz, and, in a certain sense, does not increase too slowly in a neighborhood of the global minimizer(s). We give two contributions: We show that for an optimal method adaptiveness is necessary and that randomization (Monte Carlo) yields no further advantage. We present a method that is universal in the following sense: This algorithm has the optimal rate of convergence even if neither the Lipschitz constant nor any other function parameter is known.']
