A scenario of continuous and discontinuous wetting transitions is predicted by the continuum theory of dispersion forces, which is different from that obtained by an addition of the nonretarded van der Waals interaction with a next-to-leading term. I

Wetting of ring-shaped surface domains is studied both theoretically and experi- mentally. The liquid channels covering these domains exhibit a volume-induced morphological transition from a homogeneous to a bulge state. The continuous symmetry of th

We describe an experimental setup and sample preparation procedure, which makes it possible to study highly aligned phospholipid membranes under conditions of full hydration, i.e. in excess water. While full hydration is an essential requirement to d

We present a quantitative study of specular and diffuse (non-specular) x-ray and neutron reflectivity from highly aligned phospholipid membranes deposited on solid substrates. The height-height correlation function could be obtained from the diffuse

The horizontal reflectometer REFSANS at FRM-2 in Munich/Germany has successfully been put into operation. It is dedicated to the comprehensive analysis of the air/water interface by means of specular and off-specular reflectivity as well as GISANS me

The distribution profiles of rubidium ions near polar, zwitterionic 1,2-di stearoyl-sn-glycero-3-phospho choline (DSPC) and charged, anionic 1,2-di stearoyl-sn-glycero-3-phospho glycerol (DSPG−) membranes were determined by means of anomalous X-ray

The surface of sonicated suspensions of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) in water was studied by means of X-ray-reflectivity measurements as a function of temperature and time. This revealed the generation of a surface-confined stac

Surface tension data of isobutyric-acid-water mixtures, published by Nagarajan, Webb and Widom (J. Chem. Phys., 77 (1982) 5771), are reanalysed. Contrary to the conclusion drawn by these authors, it is shown that the critical part of the surface tens

By means of electrotransport and high precision electrical resistance measurements we studied the influence of hydrostatic pressure (up to 2.2 GPa) on the diffusion coefficient and some related properties of hydrogen in niobium. The hydrogen-to-niobi

The growth and decay kinetics of macroscopic hydrogen density modes in single crystals of niobium excited by an applied electric field was measured. The samples were prepared in-situ as to prevent incoherent precipitations. At a low hydrogen concentr
