Importance of Unimolecular HO2 Elimination in the Heterogeneous OH Reaction of Highly Oxygenated Tartaric Acid Aerosol.
Results show that molecular structure can play a larger role in the heterogeneous transformation of tartaric acid (OSC = 1.5), and two structurally related dicarboxylic acids are compared to elucidate how the identity and location of functional groups (methyl and hydroxyl groups) alter heterogeneous reaction mechanisms.

The role of alkoxy radicals in the heterogeneous reaction of two structural isomers of dimethylsuccinic acid.
Two model systems are used to investigate how the relative locations of branched methyl groups control the heterogeneous reaction of OH with two isomers of dimethylsuccinic acid to reveal how the isomeric structure ultimately controls the overall competition between functionalization and fragmentation.

Compositional evolution of particle-phase reaction products and water in the heterogeneous OH oxidation of model aqueous organic aerosols
Abstract. Organic compounds present at or near the surface of aqueous droplets can be efficiently oxidized by gas-phase OH radicals, which alter the molecular distribution of the reaction productsExpand
Development of size-resolving aerosol microphysics scheme for use in a global non-hydrostatic cloud-resolving model
To simulate the evolutions of aerosol size distributions and their contributions to the aerosol-radiation and aerosol-cloud interactions, we develop the size-resolving scheme as an extension from theExpand
