I focus my efforts at PSI on free radical/molecule kinetics and nanoparticle/atmospheric aerosol characterization in terms of surface functional groups on aerosols with the goal to study aerosol health effects.

We have reinvestigated C2H5 + HI => C2H6 + I where we find a low rate constant and a positive activation energy in the range 213-653 K. We will study R + O2 <==> RO2 as a function of T with R = methyl, ethyl and t-C4H9 free radicals using synchrotron radiation and Knudsen flow reactors.
