“…The results showed that this method can rapidly generate BNBs, which can remain stable for over 60 days. Senthilkumar et al [16] used mechanical stirring to generate nanobubbles in heat transfer oil. The results showed that the nanobubbles generated had diameters of less than 200 nm, and their presence was able to improve the thermal conductivity and viscosity of the heat transfer oil.…”

Nanobubbles represent a special colloidal system, as they have high stability and large specific surface areas. The preparation of nanobubbles is currently a hot research topic, as it crucial to investigate their characteristics and expand their applications. This article explains the mechanism of generating nanobubbles based on chemical and physical methods, introduces their basic composition’s structure and properties, summarizes the methods of preparing bulk nanobubbles (BNBs) and surface nanobubbles (SNBs), and clarifies the preparation principles and techniques. Seven practical applications of nanobubbles are cited in this paper, including their use as ultrasonic contrast agents in medical imaging, drug delivery systems in drug transportation, promoters of plant growth by affecting plant respiration and water absorption at the roots, tools to remove dirt from surfaces by generating energy during nanobubble bursting, producers of high-density negative ions and free radicals to react with pollutants in wastewater, tools to reduce the resistance of the fluid flow through channels by lowering the internal friction, and means of improving the mineral flotation recovery rate by enhancing the absorption capacity of bubbles to minerals. Finally, the future development of nanobubble preparation technology is discussed, including their roles in optimizing equipment and preparation methods; improving the quantity, efficiency, stability, controllability, and homogeneity of nanobubble generation; and promoting the industrial production of nanobubbles.

“…Various factors influence their stability, including the surface charge of the bubbles, surface tension, and properties of the solution. The primary reason for the stability of nanobubbles lies in their possession of surface charge [16]. Nanobubbles with a high zeta potential exhibit greater stability.…”

“…Seddon et al proposed the hypothesis that NBs are stabilized by the “presence of adsorbed material” . While some reports have pointed to the possibility that nanobubbles could potentially be confused with impurities in the solution, , many others clearly demonstrate the existence of bulk NBs in pure water. ,,− It has been elucidated that additives such as surfactants , and electrolytes , affect NB size distribution, zeta potential, and stability. However, the concentration of such species in pure deionized water is likely too low to stabilize bulk NBs sufficiently .…”

The origin of the stability of bulk Nanobubbles (NBs) has been the object of scrutiny in recent years. The interplay between the surface charge on the NBs and the Laplace pressure resulting from the surface tension at the solvent-NB interface has often been evoked to explain the stability of the dispersed NBs. While the Laplace pressure is well understood in the community, the nature of the surface charge on the NBs has remained obscure. In this work, we aim to show that the solvent and the present ions can effectively polarize the NB surface by inducing a dipole moment, which in turn controls the NB stability. We show that the polarizability of the dispersed gas and the polarity of the dispersing solvent control the dipole-induced dipole interactions between the solvent and the NBs, and that, in turn, determines their stability in solution.
