title: Binary nucleation beyond capillarity approximation.
abstract: Large discrepancies between binary classical nucleation theory (BCNT) and experiments result from adsorption effects and inability of BCNT, based on the phenomenological capillarity approximation, to treat small clusters. We propose a model aimed at eliminating both of these deficiencies. Adsorption is taken into account within Gibbsian approximation. Binary clusters are treated by means of statistical-mechanical considerations: tracing out the molecular degrees of freedom of the more volatile component, we obtain a coarse-grained system described in terms of the single-component mean-field kinetic nucleation theory [V. I. Kalikmanov, J. Chem. Phys. 124, 124505 (2006)], allowing an adequate treatment of clusters of arbitrary size. The model opens a route toward studying binary nucleation in complex systems with nanosized critical clusters.
