Hans Sillescu
Hans Sillescu (born October 5, 1936 in Frankfurt am Main ) is a German chemist ( physical chemistry ). He is a professor emeritus at Johannes Gutenberg University Mainz .
Life
Sillescu studied chemistry from 1956 at the Johann Wolfgang Goethe University in Frankfurt am Main with a diploma in 1961 and a doctorate in 1964 (nuclear quadrupole coupling in some cobalt (III) complexes) under Hermann Hartmann , under whom he set up an NMR group and initially NMR ( according to a research focus of his teacher Hartmann) applied to complex chemistry. As a post-doctoral student he was at the University of California, Los Angeles with Daniel Kivelson and at Harvard University with Roy Gordon in 1966/67 and began to work on dynamic NMR studies. In 1968 he completed his habilitation with Hartmann at the Johann Wolfgang Goethe University in Frankfurt am Main (theory of spin-lattice relaxation in liquids).
In 1971 he became a professor for physical chemistry in Frankfurt. From 1975 until his retirement in 2002 he was a professor in Mainz (as the successor to Günter Victor Schulz ). In 1987/88 he was dean of the chemistry department there.
He deals with the theoretical and experimental investigation of slow, complex molecular dynamics, in (complex) liquids, polymers (where he is especially known for NMR studies with deuteron NMR), colloids and in the dynamics of the glass transition. He uses NMR spectroscopy (investigation of very slow rotational and translational movements), dynamic light scattering (photon correlation spectroscopy, forced Rayleigh scattering) and light microscopy with digital image processing. From 1983 to 1987 he was the spokesman for the Collaborative Research Center Chemistry and Physics of Macromolecules (which existed from 1968 to 1987). He was also involved in the SFB Glass Condition and Glass Transition of Non-Metallic Amorphous Materials .
As a hobby he plays the cello.
