Generation of nanobubbles by ceramic membrane filters: The dependence of bubble size and zeta potential on surface coating, pore size and injected gas pressure

A Henry's law method for generating bulk nanobubbles

“…A number of techniques have been reported for the generation of BNBs including single nanobubble electrolysis, [51][52][53][54][55] acoustic cavitation, 1,3,22 hydrodynamic cavitation, 56,57 fluidic oscillation, 58 nano-membrane filtration, 59 water-solvent mixing, 3,21,60,61 laser, 62,63 periodic pressure changes, 23 compression and decompression of gas, [64][65][66] and chemical reactions. 67 Each method has its own advantages and shortcomings.…”

Novel oxygen-generation from electrospun nanofibrous scaffolds with anticancer properties: synthesis of PMMA-conjugate PVP–H2O2 nanofibers, characterization, and in vitro bio-evaluation tests

“…The DO concentrations were recorded at different time intervals. This procedure was coupled with the previously designated procedure of Voss et al 34 and Ahmed et al 35 2.5.4. Mechanical strength.…”

Influence of diffuser design on selected operating variables for wastewater flotation systems: a review

“…Generation of bubbles through the saturation of water with air has limitations that include the high pressure needed for injecting the saturated liquid, the mixing of air and the recycling of gas/liquid which can lead to equipment damage or contamination due to the nature of contaminants present in the water being treated (Ahmed et al 2018). These disadvantages might be overcome by using diffusers without a recycle stream provided they generate the required bubble size for the particular or specified process.…”
