Forced oscillation dynamics of surface nanobubbles. [PDF]
The Journal of Chemical Physics, 2020 Surface nanobubbles have potential applications in the manipulation of nanoscale and biological materials, waste-water treatment, and surface cleaning.

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.

Surface Nanobubbles Nucleate Microdroplets [PDF]
Physical Review Letters, 2014 When a hydrophobic solid is in contact with water, surface nanobubbles often form at the interface. They have a lifetime many orders of magnitude longer than expected. Here, we show that they even withstand a temperature increase to temperatures close to the boiling point of bulk water; i.e., they do not nucleate larger bubbles ("superstability").

Role of substrate softness in stabilizing surface nanobubbles
Green Energy & Environment, 2020 The contact line pinning and supersaturation theory for the nanobubble stability has attracted extensive concerns from experimental investigators, and some experimenters argue that the contact line pinning is unnecessary.

Stable charged nanobubbles with distinct polarities in culture media differentially affect the viability of human iPSC-derived neurons [PDF]
Scientific ReportsNanobubbles (NBs) are gas-filled spherical structures less than 1 μm in diameter, characterized by high surface charge, long-term stability, and the ability to generate bactericidal hydroxyl radicals upon collapse. Although these unique properties enable

Formation, dissolution and properties of surface nanobubbles [PDF]
Journal of Colloid and Interface Science, 2017 Surface nanobubbles are stable gaseous phases in liquids that form on solid substrates. While their existence has been confirmed, there are many open questions related to their formation and dissolution processes along with their structures and properties, which are difficult to investigate experimentally.

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 ...

Covering Surface Nanobubbles with a NaCl Nanoblanket [PDF]
Langmuir, 2013 By letting a NaCl aqueous solution of low (0.01 M) concentration evaporate on a highly oriented pyrolytic graphite (HOPG) surface, it is possible to form a thin film of salt. However, pre-existing surface nanobubbles prevent the homogeneous coverage of the surface with the salt, keeping the footprint areas on the substrate pristine.

Particle tracking around surface nanobubbles [PDF]
Journal of Physics: Condensed Matter, 2013 The exceptionally long lifetime of surface nanobubbles remains one of the biggest questions in the field. One of the proposed mechanisms for the stability is the \emph{dynamic equilibrium} model, which describes a constant flux of gas in and out of the bubble. Here, we describe results from particle tracking experiments to measure this flow.
