Abstract
A procedure has been proposed for calculating the smallest possible thickness of the surface layer in a one-component liquid/saturated vapor system. A model of the layer homogeneous with respect to the pressure tensor has been considered. The smallest thickness of the surface layer and the molar volumes for the surface layer regions adjacent to the liquid and vapor phases have been calculated for liquid argon in the saturation line within a range from the triple point to almost critical temperature. Using published information as an example, it has been shown that the data on the distribution of the substance in the surface layer can be brought to the parameters of the proposed model.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
