• Subject Area: Statistical Physics, Nonlinear Dynamics, Complex Systems, Soft and Fluid Matter, Biological Physics
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 265191195

A09N is dedicated to nanoscale investigations of wetting and dewetting during imbibition and nucleation. It should allow a deeper understanding of surface effects on the deformation of the contact line on a nano-scopic length scale. A scanning force microscope is used to scan the contact line with a resolution of 10-30 nm. Differences between nanoscopically and macroscopically measured contact angles are analyzed. In addition to simple fluids and surfaces, mixtures and mesoporous as well as swellable surfaces are used. A nanoscale body immersed into the air/water will be used to study the local distribution of substances. This generic configuration will be compared directly with simulations.
