Heterogeneous Atmospheric Aerosol Production by Acid-Catalyzed Particle-Phase Reactions
TLDR
If acid-catalyzed heterogeneous reactions of SOA products are included in current models, the predicted SOA formation will be much greater and could have a much larger impact on climate forcing effects than the authors now predict. Expand
Formation of oligomers in secondary organic aerosol.
TLDR
Chemical reactions leading to oligomer formation provide a reasonable answer to a difficult problem associated with secondary organic aerosol production in the atmosphere as Polymerization provides a mechanism by which partitioning to the particle phase becomes favored. Expand
The use of polycyclic aromatic hydrocarbons as source signatures in receptor modeling
Abstract The purpose of this study was to explore the use of polycyclic aromatic hydrocarbons (PAH) as organic tracers and to demonstrate how their atmospheric chemical reactivity can be incorporatedExpand

TLDR
This work shows that aldehyde products can further react through heterogeneous processes, which may be a very significant SOA generation mechanism from the oxidation of aromatics in the atmosphere. Expand
Effect of acidic seed on biogenic secondary organic aerosol growth
Abstract Secondary organic aerosol (SOA) growth in the presence of acid aerosols was studied in twin 500 l Teflon bags and in a 4 m flow reactor. In Teflon bags, isoprene, acrolein and α-pinene wereExpand
Kinetic mechanism for predicting secondary organic aerosol formation from the reaction of d-limonene with ozone.
TLDR
A semi-explicit mechanism of d-limonene was developed and tested against experimental results obtained from large outdoor Teflon film chambers at the University of North Carolina (UNC) smog chamber facility and provides a reasonable prediction of the secondary aerosol mass production under different conditions.

Gas and Particle Products Distribution from the Reaction of β-Caryophyllene with Ozone
Gas and particulate reaction products from the ozonolysis of β -caryophyllene (I) in the presence of atmospheric air were investigated using a combination of gas chromatography-mass spectrometryExpand

  • 10 November 2001
TLDR
It was concluded that aldehydes, which can be produced by atmospheric photochemical reactions, can significantly contribute on secondary aerosol formation through heterogeneous reactions in the presence of an acid catalyst. Expand
Aerosol formation from the reaction of α-pinene and ozone using a gas- phase kinetics-aerosol partitioning model
As a result of new aerosol compositional information, we have implemented an exploratory model for predicting aerosol yields from the reaction of α-pinene with ozone in the atmosphere. This newExpand
The influence of humidity, sunlight, and temperature on the daytime decay of polyaromatic hydrocarbons on atmospheric soot particles.
TLDR
Estimates suggest that, at moderate humidities and temperatures, PAH daytime half-lives on airborne soot particles increased for many compounds to a period of days. Expand
