Efficient simulations of gas-grain chemistry in interstellar clouds [PDF]
Chemical reactions on dust grains are of crucial importance in interstellar chemistry because they produce molecular hydrogen and various organic molecules. Due to the submicron size of the grains and the low flux, the surface populations of reactive species are small and strongly fluctuate.
