Investigation of Chemical Agitations on Single Chemical and Biological Aerosol Particles in Air Using Optical Trapping-Raman Spectroscopy (Atmospheric Sciences)
Abstract
The goal of this project is to better understand physics and chemistry of aerosol particles at the fundamental level (single aerosol particle). In particular, we investigate single aerosol properties and their changes over time under external chemical agitation, i.e. via surface chemical reactions, leading to new insights into aerosol particle reactivity and surface chemistry. Four research objectives are (1) Trap chemical (e.g. solid oxide particles) and biological particles (pollen and spores) based on different trapping forces. Two major trapping schemes using a single laser beam or double beams will be employed to trap single particles in a closed reaction chamber or in a free space.
