Night-time oxidation. Towards a model closer to reality: mixed organic films.
In the last decade many aerosol scientists focused their efforts on quantifying the amount of organic aerosols due to cooking processes and on determining their composition. Our project aims to investigate the oxidation of organic coated aerosols, particularly when the main oxidant agent is NO3. We have already carried out experiments on single components, and we learnt that the surface tension drops much faster than the surface excess, thus it is not possible to relate them in a satisfactory way without neutron reflectometry. The next step for the NEATNOx project is to move to more realistic models for cooking aerosols, with investigations into binary mixtures of the three surfactants previously studied (methyl oleate, oleic acid and stearic acid). This will allow us to understand how the interaction between the two components affects the oxidation reaction and its rate coefficient in two systems which mix on a molecular level and one reference system which does not (as shown using complementary Brewster angle microscopy measurements). The experimental work in conjunction with the kinetic modelling interpretation will allow tentative extrapolation to atmospheric conditions.
