Stability of Surface Nanobubbles: A Molecular Dynamics Study [PDF]

open access: yesLangmuir, 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]

open access: yesLangmuir, 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 ($c=100%$, $T_{liquid} = T_{substrate}$).

Effect of impurities in description of surface nanobubbles [PDF]

open access: yesPhysical 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.

Surface nanobubbles and micropancakes [PDF]

open access: yesJournal 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 ...

Formation and coalescence of nanobubbles under controlled gas concentration and species

open access: yesAIP Advances, 2018
Using molecular dynamics simulations, the effects of gas concentration and species on the coalescence and growth of nanobubbles were systematically investigated.

Towards Understanding the Role of Surface Gas Nanostructures: Effect of Temperature Difference Pretreatment on Wetting and Flotation of Sulfide Minerals and Pb-Zn Ore

open access: yesNanomaterials, 2020
Surface nanobubbles at hydrophobic interfaces now attract much attention in various fields but their role in wetting-related phenomena is still unclear.

Remediation of Copper Contaminated Soils Using Water Containing Hydrogen Nanobubbles

open access: yesApplied Sciences, 2020
This basic research study was undertaken to use ecofriendly nanobubbles that can improve the electrokinetic remediation of copper-contaminated soil, as well as to determine that remediation efficiency.

Deformation of Surface Nanobubbles Induced by Substrate Hydrophobicity [PDF]

open access: yes, 2016
Recent experimental measurements have shown that there exists a population of nanobubbles with different curvature radii, whereas both computer simulations and theoretical analysis indicated that the curvature radii of different nanobubbles should be the

Does salting-out effect nucleate nanobubbles in water: Spontaneous nucleation?

open access: yesUltrasonics 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.

Theoretical Analysis on the Stability of Single Bulk Nanobubble

open access: yesFrontiers in Materials, 2022
As predicted by classical macroscopic theory, the lifetime for nanoscale gas bubbles is extremely short, which causes conflict when detecting stable bulk nanobubbles experimentally in recent years.
