Using model systems\, w e examine how the reactive uptake kinetics of hydroxyl radicals at the aer osol surface depends upon liquid water content and common atmospheric trac e gases such NO and SO2.  In these systems\, the OH reaction probability i s observed to be a complex and non-linear function of these environmental variables and involves the complex interplay between molecular reactivity\ , free radical cycling\, viscosity\, hygroscopic growth and decomposition. To examine the importance of interfacial chemistry on the cloud condensat ion properties of organic aerosols new Köhler curve experiments have been developed. For realistic mixed inorganic/organic aerosols\, the droplet si ze at activation is much larger than what would be predicted based upon bu lk solubility alone and points to the important role that interfacial orga nic molecules play in cloud droplet formation. \n DTSTART:20170307T180000Z DTEND:20170307T191500Z LOCATION:Room 10\, Maass Chemistry Building\, CA\, QC\, Montreal\, H3A 0B8\ , 801 rue Sherbrooke Ouest SUMMARY:Chemical Society Seminar: Dr. Kevin R.
