Aqueous Aerosols in Atmospheric Chemistry and Airborne Diseases


Gu, Alan Yalun (2022) Aqueous Aerosols in Atmospheric Chemistry and Airborne Diseases. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/4spy-az88.


Aqueous atmospheric aerosols are small droplets (typically smaller than 5 μm) suspended in the air that are comprised of water and water-soluble components. These aerosols provide an air-water interfacial reaction environment on their surfaces, and act as a medium for airborne disease transmission. In this thesis, Chapters II and V explore atmospherically relevant reactions on the aqueous aerosol surface using an online mass spectrometry, while Chapter III investigates the SARS-CoV-2 airborne transmission considering suspended virus-laden aerosols as the transmission media. Spinning off this SARS-CoV-2 work, Chapter IV describes a newly developed quantitative RNA amplification test kit for COVID-19, with an emphasis on the amplification result photo recognition component.
