Mechanical Stability of Surface Nanobubbles. [PDF]
Langmuir, 2018 Bubble cavitation is important in technologies such as noninvasive cancer treatment and diagnosis, surface cleaning, and waste-water treatment. The cavitation threshold is the critical external tensile pressure that induces unstable growth of the bubble.

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.

Surface Nanobubbles Are Stabilized by Hydrophobic Attraction. [PDF]
Physical Review Letters, 2018 The remarkably long lifetime of surface nanobubbles has perplexed researchers for two decades. The current understanding is that both contact line pinning and supersaturation of the ambient liquid are strictly required for the stability of nanobubbles, yet experiments show nanobubbles surviving in open systems and undersaturated environments.

Stability, Dynamics, and Tolerance to Undersaturation of Surface Nanobubbles. [PDF]
Physical Review Letters, 2019 The theoretical understanding of surface nanobubbles-nanoscale gaseous domains on immersed substrates-revolves around two contrasting perspectives. One perspective, which considers gas transport in the nanobubbles' vicinity, explains numerous stability ...

Temperature Dependence of Surface Nanobubbles [PDF]
ChemPhysChem, 2012 AbstractThe temperature dependence of nanobubbles was investigated experimentally using atomic force microscopy. By scanning the same area of the surface at temperatures from 51 °C to 25 °C it was possible to track geometrical changes of individual nanobubbles as the temperature was decreased.

Stability of surface and bulk nanobubbles
Current Opinion in Colloid and Interface Science, 2021 Abstract The existence of stable nanoscopic gaseous domains in liquids, or nanobubbles, has attracted both skepticism and intrigue since classical theory predicts that spherical gas bubbles cannot achieve stable equilibrium. Can we prove these gaseous domains exist, and if they do, how do they survive?

Shock-induced collapse of surface nanobubbles.
Soft Matter, 2021 The collapse of cavitation bubbles often releases high-speed liquid jets capable of surface damage, with applications in drug delivery, cancer treatment, and surface cleaning.

Collapse of Surface Nanobubbles [PDF]
Physical Review Letters, 2015 Surface attached nanobubbles populate surfaces submerged in water. These nanobubbles have a much larger contact angle and longer lifetime than predicted by classical theory. Moreover, it is difficult to distinguish them from hydrophobic droplets, e.g., polymeric contamination, using standard atomic force microscopy.

Removal of surface-attached micro- and nanobubbles by ultrasonic cavitation in microfluidics
Ultrasonics SonochemistrySurface-attached micro- and nanobubbles are known for their resistance to external forces. This study experimentally and theoretically investigates their response to strong ultrasonic fields.
