Abstract
Nanodispersions can be used to solve various practical problems, such as increasing the efficiency of heating systems, cooling of electrical equipment, intensifying oil recovery, etc., because dispersing nanoparticles in liquid media provides an inexpensive and convenient way to significantly improve various functional properties of a base fluid. Although the influence of dispersed particles on surface phenomena in systems comprising nanofluids has been studied for more than 30 years, due to a number of factors, the problem of appropriate and self-consistent description of the behavior of nanofluids will apparently remain to be the focus of scientific attention in the coming decades. This paper presents a brief review of recently published results that are of general importance for understanding the behavior of the surface tension of nanofluids, as well as the processes accompanying wetting with nanofluids and their spreading over various surfaces.
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.
