Dynamic Equilibrium Model for Surface Nanobubbles in Electrochemistry.

Langmuir, 2021
Gas bubbles are ubiquitous in electrochemical processes, particularly in water electrolysis. Due to the development of gas-evolving electrocatalysis and energy conversion technology, a deep understanding of gas bubble behaviors at the electrode surface ...

Cavitation nuclei and surface nanobubbles -- the model of non-adsorbed interfacial liquid zones

The Physics of Fluids, 2022
A theory of bubble nuclei at water-solid interfaces is presented, based on non-adsorbed interfacial liquid zones (NAILZ). It explains the low contact angle of surface nanobubbles, observed at clean solid surfaces submerged in purified water from the H-O ...

On the Shape of Surface Nanobubbles

Langmuir, 2009
Previous AFM experiments on surface nanobubbles have suggested an anomalously large contact angle theta of the bubbles (typically approximately 160 degrees measured through the water) and a possible size dependence theta(R). Here we determine theta(R) for nanobubbles on smooth, highly oriented pyrolytic graphite (HOPG) with a variety of different ...

Ultra-high Density of Gas Molecules Confined in Surface Nanobubbles in Ambient Water.

Journal of the American Chemical Society, 2020
To understand the unexpected and puzzling long-term stability of nanoscale gas bubbles, it is crucial to probe their nature and intrinsic properties. We report synchrotron-based scanning transmission X-ray microscopy (STXM) evidences of highly condensed ...

Effect of Surfactant on Electrochemically Generated Surface Nanobubbles.

Analytical Chemistry, 2021
Surfactants, mimics of contamination, play an important role in nanobubble nucleation, stability, and growth at the electrode surface. Herein, we utilize single-molecule fluorescence microscopy as a sensitive imaging tool to monitor nanobubble dynamics ...

Pinning Stabilizes Neighboring Surface Nanobubbles against Ostwald Ripening [PDF]

Langmuir, 2016
International audiencePinning of the contact line and gas oversaturation explain the stability of single surface nanobubbles. In this article we theoretically show that the pinning also suppresses the Ostwald ripening process between neighboring surface ...

New insights into the role of surface nanobubbles in bubble-particle detachment.

Langmuir, 2020
It is well recognized that an improved flotation recovery can be achieved by introducing nanobubbles to common flotation practice due to the increased capture efficiency between bubble and particle.

Understanding the stability of surface nanobubbles

Journal of Physics: Condensed Matter, 2013
Surface nanobubbles emerging at solid-liquid interfaces show extreme stability. In this paper, the stability of surface nanobubbles in degassed water is discussed and investigated by AFM. The result demonstrates that surface nanobubbles are kinetically stable and the liquid/gas interface is gas impermeable.

Slip effect of surface nanobubbles: A lattice Boltzmann study

The Physics of Fluids
Reducing the energy consumption caused by surface friction during fluid transport within channels is a critical concern in many fields. Surface nanobubbles, which are nano-scale gaseous domains attached universally to the fluid-solid interface, are a ...
