Excellent methodical considerations
July 26, 2013
The Deutsche Rheologische Gesellschaft (DRG) e.V. has honored Marcel Roth, who is junior scientist at the Max Planck Institute for Polymer Research (MPI-P), for his outstanding dissertation. He received the "Rheology Prize" during the international conference of the "Polymer Processing Society" in Nuremberg on 17th July 2013. The prize carries a value of EUR 1,500.
In his dissertation "Rheology of arrested colloids" Roth studied colloidal systems. Nowadays, these systems can be found almost everywhere, e.g. in wall color. He realized and tuned measuring and analyzing methods, which allow studying both structure and mechanical properties of those systems at the same time. Therefore, the physicist developed methods for a better analysis of pictures taken with confocal microscopes. For the first time, Roth was able to watch single rotating colloidal particles, and thus he gained further insights into structure and dynamics of those systems. His considerations to link microscopic and macroscopic perspectives offer further ideas for studying colloids.
Marcel Roth conducted research in the group of Günter Auernhammer at the MPI-P.
