Reactive Spectro-microscopy Studies of Substrate-Deposited of Organic Aerosol Particles
EMSL Project ID
30494
Abstract
This project seeks to characterize the chemical andmorphological changes of individual atmospheric particles during chemical transformations.
Chemical transformations include oxidation of these particles with atmospheric trace gases
followed by water uptake. The exact mechanisms of these reactions are poorly understood;
specifically, what species are formed at the surface and their dependence upon the type and
structure of the aerosol particles. This project will utilize a quantitative approach for reactive
spectro-microscopy studies of organic aerosols using a combination of micro-FTIR spectroscopy
and environmental scanning electron microscopy (ESEM)
