Wiesner, Urlich B. - Cornell University - Department of Chemistry and Chemical Biology

个人简介

Ulrich Wiesner studied Chemistry in Mainz, Germany, and Irvine, California. He gained his Ph.D. in 1991 with work at the Max-Planck-Institute for Polymer Research (MPI-P), Mainz, and was a postdoctoral fellow at the E.S.P.C.I. in Paris, France until 1993. He joined the Cornell MS&E faculty in 1999 following his Habilitation and became a Full Professor in 2005. He works at the interface between polymer science and solid state chemistry/physics with the goal of generating novel hierarchical and multifunctional hybrid materials. He is the co-founder of Hybrid Silica Technologies, Inc . and the recipient of multiple awards including the Carl Duisberg Memorial Award of the German Chemical Society.

研究领域

The goal of current research in the Wiesner group is to combine knowledge about the self-assembly of soft polymeric materials with the functionality of solid-state materials to generate novel hierarchical and multifunctional hybrid materials. Research results of the group on the use of blocked copolymers as structure directing agents for inorganic materials suggest that in analogy to biology, the sequence information of higher order blocked synthetic macromolecular architectures may be used to encode information about hierarchical structure of co-assemblies with ceramic or other materials. These principles may permit the design of entirely new classes of functional materials that have no analogue in the natural world with potential applications ranging from power generation and energy conversion all the way to the life sciences.
