The stabilization of colloids and dispersions is an important factor in many applications. This regards solid particles in liquids, emulsions of two immiscible liquids and foams of a liquid and a gas phase.

The focus of the research lies on the identification of stability criteria and the formation of finely dispersed systems with particle sizes in the nano- and micrometer scale. Of special interest is the structure of adsorption layers at interfaces.

Therefore methods like tensiometry, superresolution fluorescence microscopy and atomic force microscopy (AFM) are used. Rheology and Langmuir film balance provide additional information.
