Christiane Losert-Valiente Kroon has won the 2010 Marshall Stoneham Prize
23. Sep 2010 — The Marshall Stoneham Prize is a newly established prize awarded annually to an outstanding PhD thesis in the area of condensed matter and materials physics.
The Prize has been awarded to Christiane for her work on the kinetics of chemical reactions and nucleation processes in small systems, with applications to astrochemistry and aerosol science.
Stochastic Treatment of Heterogeneous Chemical Reaction and Nucleation Processes in Small Systems
Abstract: We explore a new framework for describing the kinetics of a heterogeneous chemical reaction where two particles of the same or different chemical species form a reaction product of another chemical species on the surface of a seed particle. Traditional treatments neglect the effect of statistical fluctuations in populations which are crucial when considering small physical systems. We employ techniques in a manner analogous to the treatment of quantum systems to develop a stochastic description of processes beyond the mean field approximation. This work is extended to treat heterogeneous nucleation processes of aerosols in the same fashion.
