Does the viscosity of the sub-phase effect the oxidation kinetics of surface active films on "glassy" cloud droplets? ¿ Concept Proof

Abstract: Atmospheric climate change is strongly influenced by clouds and the oxidative processing of pollutants in clouds affects droplet size and reflectivity of the planet. Clouds contain naturally occurring lipids forming films on the droplet. Oxidation and removal of this film can cause cloud evaporation or new cloud formation. Cloud droplets can occur in ¿glassy¿ states at the top of the troposphere. In this work we will determine if the kinetics of thin film oxidation are affected by a ¿glassy¿ sub-phase, i.e. can the viscosity of the sub-phase become large enough for diffusion of ozone to slow the surface reaction? Specifically we will measure the rate of oxidation of oleic acid by ozone on viscous sub-phases of glucose/water, (and compare the determined rate constant to our published work on water). This is exploratory work and may result in a well-cited paper.
