Nanobubbles (ultrafine bubbles)

2019-10-28  The rationale for bulk nanobubble stability. A review of some hypotheises for the stability of bulk nanobubbles has been produced .The likely reason for the long-lived presence of nanobubbles (first described on this website in 2007) is that the nanobubble gas/liquid interface has a negative charge [3424, 3473, 3531] that introduces an opposing force to the surface tension, so slowing or

High-Efficiency Nanobubble Coal Flotation:

2013-5-29  The high efficiency of a froth flotation process is limited to a narrow particle size range. Nanobubbles integrated into a specially designed flotation column expanded the particle size range for effective froth flotation as a result of increased probabilities of particle-bubble collision and attachment and reduced probability of detachment.

Although both methods can enhance mineral flotation, are their roles the same? There are few research studies in the field, which severely limits our understanding on mineral flotation combined with HC. Therefore, in this study, the flotation of ultrafine scheelite with HC

Nanobubble Generation and It’s Applications:: Special

There is a growing interest in nanobubble because of its wide range of potential applications. Nanobubble has been used for detergent-free cleaning, ultra-sound imaging and intracelluar drug delivery, enhanced drug susceptibility of cancer cells, and mineral processing etc. Nano-bubbles can be used as cleaning agents both for the prevention of surface fouling and for defouling surfaces.
