The Effect of the Surface Activity of Soluble Condensation Nuclei on the Thermodynamics of Heterogeneous Nucleation in Vapours

The influence of the surface activity of nuclear matter on the vapour chemical potential at the threshold of barrierless heterogeneous nucleation has been analysed taking into account the lateral interactions in the adsorbed monolayer of nuclear matter on the drop surface; the results obtained are valid within a wide size range for a condensation nucleus soluble in the drop arising on the nucleus from a vapour.
