    Curvature corrections to surface tension / V. G. Baidakov, G. Sh. Boltachev, G. G. Chernykh // Physical Review E: Statistical, Nonlinear, and Soft Matter Physics. - 2004. - Vol.70, №1. - С. 011603

Кл.слова (ненормированные):
SURFACE TENSION -- LIQUID-VAPOR INTERFACE -- BORN-GREEN-YVON
Аннотация: The paper studies the size dependence of the surface tension at a weakly curved liquid-vapor interface. Statistical expressions for the first and the second corrections to the surface tension are derived with the use of expansion of the first of the equations of the hierarchy of Born-Green-Yvon into a series in terms of the curvature of the dividing surface. A method of approximate evaluation of the second correction by information on the properties of a planar liquid-vapor interface is suggested

    First-order curvature corrections to the surface tension of multicomponent systems / G. Sh. Boltachev, J. W. P. Schmelzer, V. G. Baidakov // Journal of Colloid and Interface Sience. - 2003. - Vol.264, №1. - С. 228-236
ББК 53
Рубрики: ФИЗИКА
Кл.слова (ненормированные):
SURFACE TENSION -- PHASE COEXISTENCE -- MULTICOMPONENT SYSTEMS
Аннотация: The dependence of surface tension on curvature is investigated for the case of an equilibrium phase coexistence in multicomponent systems. Employing Gibbs's method of description of heterogeneous systems, an equation is derived to determine the dependence of surface tension on curvature for widely arbitrary paths of variation of the independent thermodynamic parameters. It is supposed hereby merely that the temperature is kept constant and that the variations of the different molar fractions are such that the radius of the dividing surface varies monotonically in dependence on the change of the state parameters of the ambient phase along any of the chosen paths. In the analysis, an approach developed by Blokhuis and Bedeaux for one-component systems is utilized. It relies on the expansion of the surface free energy on curvature of the dividing surface. An equation is derived that connects the first-order correction term in the expansion with the interaction potential of the particles in the multicomponent solution and with the two-particle distribution functions in the planar interfacial layer between the two phases coexisting in equilibrium at planar interfaces. The connection of the first-order curvature correction to the surface tension and the first moment of the pressure tensor at a planar interface is analyzed as well

    Mechanical approach to the description of liquid–vapor interfaces at low temperatures / G. Sh. Boltachev, V. G. Baidakov // Chemical Physics Letters. - 2004. - Vol.394, №4-6. - С. 329-333

Кл.слова (ненормированные):
LOW TEMPERATURES -- LENNARD-JONES -- TOLMAN LENGTH
Аннотация: The prospects of application of a mechanical model in describing the properties of planar and curved interfaces at low temperatures are investigated. It is shown that, in the framework of such approach, the Tolman length determining the first-order curvature correction to the surface tension, γ, is equal to zero. In the range of small values of the radius of curvature, R, the mechanical approach overestimates considerably the value of γ. For the Lennard-Jones potential the non-analyticity in the dependence γ(1/R) is found at 1/R = 0. It disappears for potentials decreasing more rapidly with the distance between the particles
