摘要

考虑了由于表面张力引起的拉普拉斯压力和库仑力引起的静电压力在其边界处达到平衡的体纳米气泡的稳定化问题。考虑到厚度约为1 nm的水合物层的存在，其周围有水偶极子的切向取向，其低介电常数约为3，增加了纳米气泡边界的压力。测定了稳定纳米泡的尺寸和电荷。结果表明，在盐水中，无论纳米气泡带多少电荷，水合物层的边界压力都增加了近30倍，而在淡水中，水合物层的边界压力增加了10倍至4倍。

Stability of Bulk Nanobubbles with a Hydrate Layer

The stabilization of bulk nanobubbles with a balance at their boundary of the Laplace pressure due to surface tension and electrostatic pressure due to Coulomb forces is considered. The presence of a hydrate layer of thickness ~1 nm with a tangential orientation of water dipoles around it is taken into account, the low permittivity of which, approximately equal to 3, increases the pressure at the boundary of the nanobubble. The dimensions and charge of a stable nanobubble are determined. It is shown that in salt water, the hydrate layer, regardless of the charge of the nanobubble, increases the pressure at its boundary by almost 30 times, and in fresh water—from 10 to 4 times.

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.
