A Deliberation on Nanobubbles at Surfaces and in Bulk
ChemPhysChem, 2012 AbstractSurface and bulk nanobubbles are two types of nanoscopic gaseous domain that have recently been discovered in interfacial physics. Both are expected to be unstable to dissolution because of the high internal pressure driving diffusion and the surface tension which squeezes the gas out, but there is a rapidly growing body of experimental ...

Pinning and gas oversaturation imply stable single surface nanobubbles [PDF]
, 2015 Surface nanobubbles are experimentally known to survive for days at hydrophobic surfaces immersed in gas-oversaturated water. This is different from bulk nanobubbles, which are pressed out by the Laplace pressure against any gas oversaturation and ...

Surface-Templated Nanobubbles Protect Proteins from Surface-Mediated Denaturation [PDF]
, 2019 In this Letter, we report that surface-bound nanobubbles reduce protein denaturation on methylated glass by irreversible protein shell formation. Single-molecule total internal reflection fluorescence (SM-TIRF) microscopy was combined with intramolecular

The study of surface wetting, nanobubbles and boundary slip with an applied voltage: A review
Beilstein Journal of Nanotechnology, 2014 The drag of fluid flow at the solid–liquid interface in the micro/nanoscale is an important issue in micro/nanofluidic systems. Drag depends on the surface wetting, nanobubbles, surface charge and boundary slip.

Dynamic Surface Tension Enhances the Stability of Nanobubbles in Xylem Sap
Frontiers in Plant Science, 2021 Air seeded nanobubbles have recently been observed within tree sap under negative pressure. They are stabilized by an as yet unidentified process, although some embolize their vessels in extreme circumstances.

Effect of Disjoining Pressure on Surface Nanobubbles
Langmuir, 2016 In gas-oversaturated solutions, stable surface nanobubbles can exist thanks to a balance between the Laplace pressure and the gas overpressure, provided the contact line of the bubble is pinned. In this article, we analyze how the disjoining pressure originating from the van der Waals interactions of the liquid and the gas with the surface affects the ...

Thermodynamic analysis of nanobubbles on a hydrophobic surface [PDF]
Izvestiya vysshikh uchebnykh zavedenii. Fizika, 2019 The paper presents a thermodynamic analysis of the formation of an equilibrium nanobubble at a smooth, hydrophobic solid/water interface. The analysis utilizes the Kelvin equation and the electrostatic energy of the bubble/water electric double layer.
