It is shown that electrostatic pressure arising from the repulsion of ions in the Stern layer around space charge of bulk nanobubbles is the main factor of their stability.

In this article, a new formula for the electrostatic pressure (EP) inside bulk nanobubbles (BNB) is derived. Based on the solution of the Boltzmann-Laplace equation, the value of the EP is calculated and it is shown that under certain conditions, for

The paper investigates the formation and stability of the surface nanobubbles with regard to the line tension at the triple phase boundary; the pinning effect, when the bubble stands on the surface and the triple phase boundary does not move; and the

This work studies the formation of a charged equilibrium nanobubble on a smooth hydrophobic solid–water interface. Expressions are given for the change in the Gibbs energy of the system, taking into account the Kelvin capillary equation, the electr

Line tension is calculated for a simple model of a surface nanobubble formed on a smooth hydrophobic substrate. It is shown that, with an increase in the contact angle at a certain critical value, the surface tension changes sign from positive to neg

The paper presents a thermodynamic analysis of the formation of an equilibrium nanobubble at a smooth, hydrophobic solid/water interface. The analysis utilizes the Kelvin equation and the electrostatic energy of the bubble/water electric double layer

The formation and stability of surface-charged nanobubbles with fixed boundaries of substrate contact (so-called “pinning of contact lines”) was studied theoretically. Thermodynamic analysis showed that, for some sizes of nanobubbles, the Gibbs e
