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.

Stability and Free Radical Production for CO2 and H2 in Air Nanobubbles in Ethanol Aqueous Solution
Nanomaterials, 2022 In this study, 8% hydrogen (H2) in argon (Ar) and carbon dioxide (CO2) gas nanobubbles was produced at 10, 30, and 50 vol.% of ethanol aqueous solution by the high-speed agitation method with gas.

Nanobubble Enhances Rutile Flotation Separation in Styrene Phosphoric Acid System
Separations, 2023 Due to the weak hydrophobicity of styrene phosphoric acid (SPA), the amount used as a collector for rutile flotation is too large, resulting in high beneficiation costs. In this study, SPA was modified by nanobubbles to enhance its hydrophobicity.

Thermodynamics of Surface Nanobubbles [PDF]
Langmuir, 2016 In this paper, we examine the thermodynamic stability of surface nanobubbles. The appropriate free energy is defined for the system of nanobubbles on a solid surface submerged in a supersaturated liquid solution at constant pressure and temperature, under conditions where an individual nanobubble is not in diffusive contact with a gas phase outside of ...

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 ...

PLoS ONE, 2013 Nanobubbles and microbubbles are non-invasive ultrasound imaging contrast agents that may potentially enhance diagnosis of tumors. However, to date, both nanobubbles and microbubbles display poor in vivo tumor-selectivity over non-targeted organs such as

Perspectives on surface nanobubbles [PDF]
Biomicrofluidics, 2014 Materials of nanoscale size exhibit properties that macroscopic materials often do not have. The same holds for bubbles on the nanoscale: nanoscale gaseous domains on a solid-liquid interface have surprising properties. These include the shape, the long life time, and even superstability.

The Optimized Fabrication of a Novel Nanobubble for Tumor Imaging
Frontiers in Pharmacology, 2019 Nanobubbles with a size of less than 1 µm can be used as ultrasound contrast agents for diagnosis and as drug/gene carriers for therapy. However, the optimal method of preparing uniform-sized nanobubbles is considered controversial.
