Oil-in-water and water-in-oil emulsions are often employed as lubricants. In many applications of emulsion lubricants both the deformation of the bounding solid surfaces and the pressure dependence of the viscosity of the lubricant contribute essentially to performance, thus defining lubrication in the elastohydrodynamic (EHD) mode. In this paper we investigate lubrication with liquid-liquid binary mixtures of two Newtonian fluids in an EHD conjunction, and discuss the effect of varying the parameters of the problem on pressure, film thickness and volume fraction distribution. The basic theory of lubrication with liquid-liquid mixtures is contained in an earlier publication (Al-Sharif et al., 1992), here we use the theory to study an important application.

Dozens of papers have been published recently describing adsorption processes from solutions on to solid surfaces, but a certain lack of understanding of this problem is still observed. This article deals with the description of adsorption from binary solutions of non-electrolytes on to solids. This description covers adsorption both on homogeneous and heterogeneous surfaces from ideal and non-ideal liquid mixtures. Some important factors determining the adsorption process, i.e. the heterogeneity of the solid surface, interactions between the species in the bulk and surface phases, differences in molecular sizes of the adsorbate molecules, etc., have been discussed. The main attention has been focused on the Dubinin–Radushkevich equation and its application in the description of adsorption from solutions on to energetically, heterogeneous adsorbents. Numerous model calculations have been reported for this equation and several experimental systems have been analyzed. The application of the Dubinin–Radushkevich equation in characterizing liquid adsorption on to various carbons has been demonstrated.
