Physics at Interfaces

We study the structure and dynamics of interfaces. Our general aim is to derive a simple quantitative description of soft matter interfacial phenomena. Major topics are interfacial forces and wetting, in particular wetting of super liquid-repellent surfaces. We investigate liquids that are internally structured at different length scales, such as polymer melts, solutions, dispersions, or emulsions. The methods we use include scanning probe techniques, confocal microscopy, X-ray and light scattering, and focused ion beam. To expand the range of length and time scales accessible, new methods are continuously developed. Our goal is to solve fundamental questions, with the perspective of future applications.
