Quantifying interfacial tensions of surface nanobubbles: How far can Young's equation explain?
Nanoscale, 2022 Nanobubbles at solid-liquid interfaces play a key role in various physicochemical phenomena and it is crucial to understand their unique properties. However, little is known about their interfacial tensions due to the lack of reliable calculation methods.

Stability of Surface Nanobubbles: A Molecular Dynamics Study [PDF]
Langmuir, 2016 The stability and growth or dissolution of a single surface nanobubble on a chemically patterned surface are studied by Molecular Dynamics (MD) simulations of binary mixtures consisting of Lennard-Jones (LJ) particles. Our simulations reveal how pinning of the three-phase contact line on the surface can lead to the stability of the surface nanobubble ...

Surface Nanobubbles as a Function of Gas Type [PDF]
Langmuir, 2011 We experimentally investigate the nucleation of surface nanobubbles on PFDTS-coated silicon as a function of the specific gas dissolved in the water. In each case we restrict ourselves to equilibrium conditions ($c=100%$, $T_{liquid} = T_{substrate}$).

Identifying surface attached nanobubbles
, 2021 Surface attached nanobubbles are spherical capped shaped gas bubbles that remain stable in size in saturated liquids. Their positional stability resulted in a manifold of experimental techniques to record their topography, softness, and chemical ...

Surface nanobubbles and micropancakes [PDF]
Journal of Physics: Condensed Matter, 2013 When looking at a wetted surface with a technique that can probe the nanoscale, a high surface coverage of gas bubbles is often revealed. So what? Well, if we believe in classical diffusion, these bubbles should dissolve in microseconds, but in reality they are found to remain stable for as long as anyone has observed (five days thus far, which is 10 ...

Effect of impurities in description of surface nanobubbles [PDF]
Physical Review E, 2010 Surface nanobubbles emerging at solid-liquid interfaces of submerged hydrophobic surfaces show extreme stability and very small (gas-side) contact angles. In a recent study Ducker (W. A. Ducker, Langmuir 25, 8907 (2009).) conjectured that these effects may arise from the presence of impurities at the air-water interface of the nanobubbles.

Does salting-out effect nucleate nanobubbles in water: Spontaneous nucleation?
Ultrasonics Sonochemistry, 2022 The solubility of gases in aqueous salt solution decreases with the salt concentration, often termed the “salting-out effect.” The dissolution of salt in water is followed by dissociation of salt and further solvation of ions with water molecules.
