The role of long range dispersion forces plays a significant role in the adsorption of weakly chemisorbed molecules, as demonstrated by our first-principles calculations with the van der Waals density functional (vdW-DF) applied to the model system salicyl ...
A sessile droplet can deform the surface of a soft solid not only with its weight. The surface tension pulls up a ridge at the perimeter of the drop, and the capillary pressure embosses a quasi-spherical dimple underneath the drop. This holds for the case ...
Molecular self-assembly at metal surfaces has been recognized as an efficient strategy to create supramolecular nanoarchitectures with promising functionalities. The focus of this thesis lies on the strong electron accepting molecule 7,7,8,8-tetracyanoquin ...
There are many aspects of the dynamics of liquids wetting solid surfaces that are not fully understood. One such aspect is what happens at the first instance of contact. We study the dynamics of a partially wetting fluid drop as it approaches a solid surfa ...
The structure of ultrathin NaCl films on Au(1 1 1) and on Au(11 12 12), as well as the one of bimolecular 3,4,9,10-perylenetetracarboxylic diimide (PTCDI) and 1,4-bis-(2,4-diamino-1,3,5,-triazine)-benzene (BDATB) islands on NaCl films on both surfaces have ...
A new iron tellurite halide Fe3Te3O10Cl has been identified that crystallizes in the monoclinic space group P2(1)/c. The crystal structure comprises channels where the Cl ions and also the stereochemically active lone-pair electrons on Te4+ are located. Th ...
Plasma conditions for microcrystalline silicon deposition generally require a high flux of atomic hydrogen, relative to SiH alpha=0 -> 3 radicals, on the growing film. The necessary dominant partial pressure of hydrogen in the plasma is conventionally obta ...
A 2D phase-field model has been developed in order to describe the morphology of a pore forming within interdendritic liquid channels and the geometrical effect of mechanical contacts with neighboring solid. The distribution of the solid, liquid and gas ph ...

A 2D phase field model has been developed to describe the shape of a pore formed within interdendritic liquid channels. The influence of the solid, which can force the pore to adopt a non-spherical shape, is taken into account through the geometry of the d ...
