A review of aerosol chemistry in Asia: insights from aerosol mass spectrometer measurements
Aerosol mass spectrometer has been widely deployed in Asia for real-time characterization of aerosol chemistry, and has significantly improved our understanding of the sources, properties, and formation processes of aerosols in a complex environment.

Secondary organic aerosol formation from evaporated biofuels: comparison to gasoline and correction for vapor wall losses
With an ongoing interest in displacing petroleum-based sources of energy with biofuels, we measure and model the formation and composition of secondary organic aerosol (SOA) from organic compounds present in biofuels.

Evidence for a kinetically controlled burying mechanism for growth of high viscosity secondary organic aerosol
The incorporation of organic nitrates into viscous secondary organic aerosol during particle formation is enhanced relative to expected equilibrium partitioning, and is best described by a kinetically controlled “burying” mechanism.

N2O5 reactive uptake kinetics and chlorine activation on authentic biomass-burning aerosol
The reactive uptake kinetics of nitrogen pentoxide (N2O5) to authentic biomass-burning aerosol and the production of nitryl chloride (ClNO2) was determined using an entrained aerosol flow tube reactor.

Human occupant contribution to secondary aerosol mass in the indoor environment
Occupancy in indoor spaces can contribute to indoor aerosol mass via reactions of oxidants such as ozone with skin constituents and subsequent partitioning of those oxidation product to existing aerosol.

Atmospheric OH oxidation chemistry of trifluralin and acetochlor
Herbicides react with atmospheric OH, producing multiple oxidation products, including HNCO; these products contribute little to secondary organic aerosol.
