Generation and reduction of bulk nanobubbles by ultrasonic irradiation [PDF]

To develop a compact generator of bulk nanobubbles (ultrafine bubbles), ultrasound was irradiated to ultrapure water. Effects of ultrasonic power and frequency on nanobubble concentration and diameter were investigated.

The Quest for Industrially and Environmentally Efficient Nanobubble Engineering: Electric-Field versus Mechanical Generation Approaches

Applied Sciences
Nanobubbles (NBs) are gaseous domains at the nanoscale that can exist in bulk liquid or on solid surfaces. They are noteworthy for their high potential for real-world applications and their long (meta)stability.

(Non)Existence of Bulk Nanobubbles: The Role of Ultrasonic Cavitation and Organic Solutes in Water

, 2019
A drawback of studies on bulk nanobubbles is the absence of direct proof that the nano-objects reported are really nanobubbles. The aim of our work was to provide such a proof or disproof.

Radical generation and bactericidal activity of nanobubbles produced by ultrasonic irradiation of carbonated water

Ultrasonics Sonochemistry
Our previous study showed that nanobubbles (NBs) encapsulating CO2 gas have bactericidal activity due to reactive oxygen species (ROS) (Yamaguchi et al., 2020).

Collapse of surface nanobubbles

, 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.

Studying the Effects of Dissolved Noble Gases and High Hydrostatic Pressure on the Spherical DOPC Bilayer Using Molecular Dynamic Simulations

Membranes
Fine-grained molecular dynamics simulations have been conducted to depict lipid objects enclosed in water and interacting with a series of noble gases dissolved in the medium. The simple point-charge (SPC) water system, featuring a boundary composed of 1,

Environmentally Sustainable and Energy-Efficient Nanobubble Engineering: Applications in the Oil and Fuels Sector

Fuels
In bulk liquid or on solid surfaces, nanobubbles (NBs) are gaseous domains at the nanoscale. They stand out due to their extended (meta)stability and great potential for use in practical settings. However, due to the high energy cost of bubble generation,
