A History of Nanobubbles
TL;DR: The history of nanobubbles is followed from the earliest experiments pointing to their existence to recent years, and the dominant approach to understanding bubble stability becomes a consideration of the rate of bubble dissolution.

Cleaning with Bulk Nanobubbles

TL;DR: It is shown that nanobubbles can prevent the fouling of surfaces and that they can also clean already fouled surfaces and it is argued that in practical applications where cleaning is carried out rapidly using a high degree of mechanical agitation the role of cleaning agents is not primarily in assisting the removal of soil but in suspending the soil that is removed by mechanical action and preventing it from redepositing onto surfaces.

Concentration determination of oxygen nanobubbles in electrolyzed water
TL;DR: A modified Winkler method was developed to measure total oxygen concentration more accurately, which agreed with the results obtained from the 10-fold dilution experiment, and demonstrated that the stability of the nanobubbles was sufficient for chemical reaction and solvation to bulk solution.

Formation and Stability of Bulk Nanobubbles Generated by Ethanol–Water Exchange
Jie Qiu,Jie Qiu,Zheng-Lei Zou,Shuo Wang,Xingya Wang,Lei Wang,Lei Wang,Yaming Dong,Hongwei Zhao,Lijuan Zhang,Jun Hu,Jun Hu +11 more
TL;DR: The results show that the concentration of the bulk nanobubbles produced by this method is about five times greater than that in the degassed group, which indicates the existence of bulk gas nanobUBbles.

Electrolyzed-reduced water scavenges active oxygen species and protects dna from oxidative damage

TL;DR: Reduced water suppresses single-strand breakage of DNA b active oxygen species produced by the Cu(II)-catalyzed oxidation of ascorbic acid in a dose-dependent manner, suggesting that reduced water can scavenge not only O2.- and H2O2, but also 1O2 and .OH.

Behavior of overpotential—deposited species in Faradaic reactions—II. ac Impedance measurements on H2 evolution kinetics at activated and unactivated Pt cathodes
TL;DR: In this article, the behavior of the opd H species in the H 2 evolution reaction (h.r) proceeding with appreciable net cathodic current at activated and unactivated rotated Pt electrodes is investigated by means of impedance spectrum measurements.

Pulsed electrogeneration of bubbles for electroflotation
TL;DR: In this article, the effect of interrupted current (pulsed) electrolysis on the generation of gas bubbles is investigated. And a mechanism based on local potential gradients is proposed to explain this phenomenon.

An experimental investigation of bubble-induced free convection in a small electrochemical cell
P. Boissonneau,P. Byrne +1 more
TL;DR: In this paper, a small, enclosed rectangular cell was used to electrolyse both a Na2SO4 and a NaCl/NaClO3 solution, in order to produce hydrogen and oxygen bubbles at one or both of the electrodes.

Low Hydrogen Overpotential Nanocrystalline Ni‐Mo Cathodes for Alkaline Water Electrolysis
TL;DR: In this paper, the formation process and structural properties of nanocrystalline alloys were investigated and the active phase is a metastable solid solution of Mo in fcc Ni whose electrocatalytic activity is associated with the reduction in the size of the crystallites and correlates with the expansion of the Ni lattice.
