Bubble technology has proven to be an efficient technique of reducing environmental pollution, strengthening water treatment procedures, and increasing production in industrial and agricultural applications. Nanobubbles (NBs) in liquids have several intriguing properties, including low buoyancy, high mass transfer efficiency, and high reactivity. In particular, NBs smaller than 200 nm are unexpectedly stable. However, determining the underlying mechanism of the stability of NBs in a solution is difficult. Researchers in South Korea investigated the number and stability of high-concentration NBs under various conditions. The results showed that the number and concentration of NBs can be maintained at approximately 80–90% under various conditions, such as aging, temperature, centrifugation, shaking, and stirring. According to the researchers NBs possess significant potential for use in mass production and distribution in bubble technologies… read more. Open Access TECHNICAL ARTICLEÂ
