"The utilization of artificial snow for environmentally relevant (photo)chemical studies was systematically investigated. The SSA of artificial snow grains produced in liquid nitrogen was determined using valerophenone photochemistry to estimate the surface coverage by small hydrophobic contaminants. The initial ketone loading, only about 12 orders of magnitude higher than the contaminant concentrations found in nature, was already well below monolayer coverage. We found that the efficiency of out-of-cage reactions decreased at much higher temperatures than those for frozen solutions; however, the cage effect was essentially the same no matter what technique of snow production or ketone deposition/uptake was used. The experimental observation that the contaminant molecules are initially self-associated even at the lowest concentrations was supported by DFT calculations." . .
