Use of SEM/EDX Analysis to Study the Oxidation of Aerosol by Hydroxyl Radical

Lead Institution
University of California, Irvine
Principal Investigator
Barbara Finlayson-Pitts
Project type
Exploratory Research
Unique chemistry at the air-water interface between chloride ion in sea salt aerosol and the hydroxyl radical (OH) has been suggested to play a major role in the production of increased levels of…

Molecular dynamics of aqueous NaNO3 and NaCl solutions: The surface propensity and thermodynamic properties of aqueous anions (Summer Research Institute, PNNL Scope #16248)

Lead Institution
University of California, Irvine
Principal Investigator
Barbara Finlayson-Pitts
Project type
Exploratory Research
Unique interface chemistry at the surface of sea-salt particles, comprised primarily of aqueous sodium chloride, has been postulated as an important source of photochemically active chlorine in the…

Secondary Organic Aerosol Formation from Nitrate Photochemistry

Lead Institution
University of California, Irvine
Principal Investigator
Barbara Finlayson-Pitts
Project type
Large-Scale EMSL Research
Secondary organic aerosols (SOA) in the troposphere are a major component of particulate matter and hence of interest with respect to health effects, visibility and radiative forcing. However, their…

Laboratory Studies of Atmospheric processing of sea salt.

Lead Institution
University of California, Irvine
Principal Investigator
Barbara Finlayson-Pitts
Project type
Exploratory Research
We propose two different projects: 1. Mechanism of the Reaction of NaCl and NaBr with O3 and OH. Previous studies in our laboratory of the reaction of OH with deliquesced NaCl particles showed…

Physical Chemistry of Heterogeneous Atmospheric Processes

Lead Institution
University of California, Irvine
Principal Investigator
Douglas Tobias
Project type
Capability Research
It is increasingly recognized that the physics and chemistry of the atmosphere is significantly influenced by the interfacial structure and properties of atmospheric particles. While the homogeneous…
