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.

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.
