Abstract
Basic thermodynamic characteristics (density distribution profile near the surface of a nanoparticle, adsorption, and interfacial surface tension) of the structureless nanoparticle-vapor/liquid equilibrium system are calculated using a unified approach. A joint solution of the basic equation in the Van der Waals theory of an inhomogeneous medium for the density distribution profile in the spherical system of coordinates and the Gibbs equation for the interfacial tension and absorption is obtained. The features of nucleation of nanoparticles are considered. The results generalize some familiar formulas and provide a more adequate interpretation of experimental results.
