Hans-Jürgen Butt studies the structure and dynamics of interfaces. The aim is to better understand the relationship between structural changes, dynamics, and the driving forces. more

We develop and study adaptive surfaces and surfaces adapting to external trigger. Our aim is to find mechanical and chemical durable surface repelling fluids as water and blood, as well as to study these interfaces for their physical behavior. more

We are an interdisciplinary group of scanning force microscopy (SFM) enthusiasts, constantly exploring the limits of this fascinating microscopy method. The goal is to understand the underlying physics of nanoscale systems.  more

We investigate forces associated with sliding drops and apply advanced scanning force microscopy methods. more

We develop fluorescence correlation spectroscopy and related methods to address research questions in the field of polymer, colloid and interface science.  more

Studying surface interactions and wetting properties at the nano- and microscale, we aim for novel applications such as the production of supraparticles on superamphiphobic surfaces or water desalination by membrane distillation. more

I am interested in understanding the physical and chemical processes that lead to charge separation in sliding droplets. I mainly focus on the detection of droplet and surface charges using different methods. more

As a Ph.D. student I am working on charge separation in water droplets. My goal is to study these effects on structured surfaces. My focus is fabricating Janus pillars with photolithography and plasma and/or chemical treatment. I am investigating the chemical and physical processes underlying the electrification of polymer-water contacts using various surface and interfacial analysis techniques.
