Probing the Surfaces of Atmospheric Organic Particles and the Implications for Climate Change, Air Quality, Visibility and Bioavailability
Abstract
The overall goal of this project was to elucidate the role of the surface in airborne particle systems during uptake of organic gases as well as to understand the 3-D composition in these systems in terms of differences between surface and bulk composition. Specific goals were: To develop and apply mass spectrometry techniques for differentiating molecular surface composition from that of the bulk for model laboratory systems, and apply these to more complex systems to understand surface and bulk composition during oxidation reactions. To understand gas-surface interactions in complex, multiphase systems in order to explain mechanisms of particle growth that lead to nonuniformities in composition between the surface and the bulk.
