Capillary phenomena in extremely thin zeolite channels and metal-dielectric interaction

The experimental results on capillary phenomena in channels of atom-scale diameters comparable with the interface transition layer thickness (1--1.5 {}) are reported. A simple model for the interface metal-dielectric layer is proposed. It is based on the van der Waals bond as a weak excimer interaction of the fluctuation origin. Some aspects of interphase interaction as applied to adsorption, catalysis, energetics, and electronics are discussed.
