Based on the concept of radius-dependent surface tension (ST), two physically different theories of the stability of bulk nanobubbles (BNB) – the theory of electrostatic pressure (EP) and the theory of adsorption of surfactants – are combined. The obtained analytical expressions allow to calculate the radius of stationary BNB at different dissolved gas saturation levels.
