Biography

Ranko Richert is a Professor of Chemistry and Biochemistry in the School of Molecular Sciences at Arizona State University. His research interests focus on the physical chemistry of soft materials, with emphasis on glass transition phenomena. After receiving his undergraduate degree in physics in 1982 and his Ph.D. (Dr.rer.nat.) in 1985 in physical chemistry from Marburg University, Germany, he obtained the 'Habilitation' degree in 1991. He was awarded a 'Minerva' fellowship from the Max-Planck-Gesellschaft for a postdoctoral stay at the School of Chemistry, Tel Aviv University, Israel in 1992/93. Beginning 1993, Ranko Richert held a senior researcher position at the Max-Planck Institute for Polymer Research in Mainz, Germany, and was lecturer since 1994 in the Department of Physical Chemistry at the University of Mainz before joining the ASU faculty in the fall of 1999. His research activities in the School of Molecular Sciences involve experiments based on solvation dynamics and dielectric relaxation techniques. Current research interests of the group include the structure and dynamics of liquids and glasses, phase and glass transitions, linear and non-linear dielectric relaxation spectroscopies, confinement and interfacial effects, as well as thermodynamics of viscous mterials.

Education

Ph.D., Marburg (Germany), 1985

Research Interests

The research in this group addresses the physical chemistry of glass-forming liquids and soft matter by dielectric relaxation experiments and by optical spectroscopy. We are interested in understanding the relaxation and transport phenomena in disordered materials and how they relate to the microscopic structure and dynamics. Our research topics cover phenomena associated with glass transitions, interfacial effects, geometric confinement, relaxation and retardation processes, non-linear responses, physical aging effects, spatial heterogeneities, and the relation between macroscopic and microscopic properties.

The laboratory offers a variety of highly sensitive equipment for dielectric retardation and relaxation measurements. The orientational motion of molecules as well as the translational motion of ions can be recorded in a fully automated fashion over a wide range of frequencies, 20 nHz to 10 MHz, temperatures, 25 K to 475 K, and for fields up to 600 kV/cm. Typical samples are organic supercooled liquids, polymeric materials, hydrogen bonded liquids, biological and pharmaceutical materials, and other glass-forming systems.

The optical laboratory is designed to measure phosphorescence solvation dynamics in a time window from 10 �s to 1 s and for temperatures in the range 25 K to 325 K by recording S0 - T1 (0-0) emission spectra and depolarization as a function of time. This technique of solvation dynamics probes dielectric and/or mechanical relaxation phenomena on molecular spatial scales (23 molecular diameters resolution). We also measure the rotational behavior of the probe molecules by time resolved optical anisotropy. Typical samples are organic supercooled liquids and glasses as well as polymeric materials, as bulk sample or spatially confined to nanoporous media.
