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 ($c=100%$, $T_{liquid} = T_{substrate}$).

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.

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 ...

Nonintrusive Optical Visualization of Surface Nanobubbles [PDF]
Physical Review Letters, 2012 Individual surface nanobubbles are visualized with nonintrusive optical interference-enhanced reflection microscopy, demonstrating that their formation is not a consequence of the hitherto used intrusive atomic force microscopy technique. We then use this new and fast technique to demonstrate that surface nanobubbles form in less than a few seconds ...

Why Surface Nanobubbles Live for Hours [PDF]
Physical Review Letters, 2013 We present a theoretical model for the experimentally found but counter-intuitive exceptionally long lifetime of surface nanobubbles. We can explain why, under normal experimental conditions, surface nanobubbles are stable for many hours or even up to days rather than the expected microseconds.

Formation and coalescence of nanobubbles under controlled gas concentration and species
AIP Advances, 2018 Using molecular dynamics simulations, the effects of gas concentration and species on the coalescence and growth of nanobubbles were systematically investigated.

Surface nanobubbles and nanodroplets [PDF]
Reviews of Modern Physics, 2015 Surface nanobubbles are nanoscopic gaseous domains on immersed substrates which can survive for days. They were first speculated to exist about 20 years ago, based on stepwise features in force curves between two hydrophobic surfaces, eventually leading to the first atomic force microscopy (AFM) image in 2000.

Remediation of Copper Contaminated Soils Using Water Containing Hydrogen Nanobubbles
Applied 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.

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.
