Particle sizes extend from the nanometer range over more than four orders of magnitude.
The subject of aerosols is of great importance in many applied fields such as material science, microelectronics, biotechnology, or climatology and environmental sciences. These applications require however a systematic, fundamental studies of physics of aerosols and a development of unique experimental tools. To contribute to those vital questions a broad research activities in this area are undertaken by the Aerosol Physics Group. Among other topics aerosol dynamics and optics is experimentally and theoretically investigated. Radiative heat transfer studies and scattering of light in model systems and in atmospheric aerosols are studied.
