THERMODYNAMIC ANALYSIS OF THE STABILITY OF NANOBUBBLES IN WATER

Abstract

Taking into account the influence of the chemical potential of the components in the gas phase and water, the characteristic parameters of stable nanoscale bubbles (charge, pressure, density of adsorbed ions) in an aqueous medium are determined. It is shown that on reduction of a charge of a nanobubble the radius of its steady state decreases. The adsorbed ions occupy 0.1% of the surface area of a nanobubble with a radius of 100 nm. The main contribution to the pressure gives water vapor. The total pressure of nitrogen and water vapor in it does not exceed a fraction of a percent at 1 atm.
