The evaporation has been assumed to be slow sufficiently for ensuring the validity of the quasi-stationary approximation. The smallness of the Peclet number has also been accepted, which corresponds to low velocities of the convective flows as compared with the velocity of the diffusion transfer of an impurity.

In the first case, the Laplace pressure is compensated by the electrostatic pressure at the bubble boundary; in the second case, it is compensated by the effect of the electrofreezing of its Δ-layer in a high electric field. It is shown that, in salt-free water, a lower nanobubble charge is required for the formation of an ice shell than in the case of the Coulomb stabilization mechanism.

The charge relaxation in an oscillating charged water droplet affects the intensity of its electromagnetic radiation due to the conductivity of water. The highest electromagnetic radiation intensity is inherent in an ideally conducting liquid droplet. It is an order of magnitude higher than the radiation intensity of a liquid droplet with a finite conductivity. The lowest radiation intensity is inherent in a droplet of a dielectric liquid with a frozen-in charge.

This phenomenon manifests itself during the fabrication or operation of a device and plays a negative or positive role. The paper describes a method that makes it possible to estimate the capillary force between hydrophilic rough surfaces as a function of the relative humidity and the nominal contact area. The method is based on counting the number of roughness asperities, which are able to form capillary bridges spontaneously. To implement the method, detailed information about the roughness of the contacting surfaces is required, which can be obtained using an atomic force microscope (AFM). The idea of the method is illustrated, using as an example, deposited gold films of different thicknesses that come into contact with a smooth silicon surface. AFM scans of a surface with an area of 20 × 20 µm<sup>2</sup> and a resolution of 4096 pixels per line are used. The developed theory reproduces the basic patterns observed experimentally. In particular, it is shown that the relative role of capillary forces decreases with an increase in the nominal contact area, and dispersion forces begin to play a major role in adhesion.
