Interfacial and Multiphase Chemistry of Metal-Containing Atmospheric Dust Particles
EMSL Project ID
40098
Abstract
This proposal is to use EMSL capabilities to perform laboratory studies to better understand how the properties of metal-containing atmospheric particles change as they undergo atmospheric transport. We would like to investigate formation of nanoparticles from authentic dust particles, redistribution of ions on surface in surfaces of clay minerals, and modifications of surface composition. The impact of organics on these transformations will also be explored.
