Research progress on bulk nanobubbles
Particuology, 2022Abstract There are still fundamental problems lying in the basic research of bulk nanobubbles. Are the bulk nanobubbles reported in the literature nano scale bubbles or contaminants in fact? At present, there is not yet sufficient experimental evidence to show that the bulk nanoparticles are only gas bubbles but not other nano scale contaminants.

Investigating the Existence of Bulk Nanobubbles with Ultrasound
ChemPhysChem, 2016AbstractNanobubbles are expected to dissolve in milliseconds. Experimental evidence of nanobubbles that were stable for days had thus been first received with circumspection. If the large number of experimental confirmations has now made clear that surface nanobubbles could exist, bulk nanobubbles are still subject to debate.

Formation and Stability of Bulk Nanobubbles in Different Solutions
Langmuir, 2019The existence of bulk nanobubbles is still controversial in spite of their significance in a large range of applications. Here, we developed a new method of compression-decompression to produce controllably bulk nanobubbles. Then, we further investigated the generation of bulk nanobubbles in pure water, acid, alkaline, and salt solutions using ...

Ion adsorption stabilizes bulk nanobubbles
Journal of Colloid and Interface Science, 2022The mechanism leading to the extraordinary stability of bulk nanobubbles in aqueous solutions remains an outstanding problem in soft matter, modern surface science, and physical chemistry science. In this work, the stability of bulk nanobubbles in electrolyte solutions under different pH levels and ionic strengths is studied.

Conditions of nucleation and stability of bulk nanobubbles
Izvestiya vysshikh uchebnykh zavedenii. Fizika, 2022The thermodynamic analysis of the nucleation of bulk nanobubbles (BNB) in a supersaturated aqueous solution is carried out. In the model of a charged BNB with double electric layer (DEL), the minimum work of nucleation and the radius of the critical the embryo are calculated.

Formation and Stability of Bulk Nanobubbles by Vibration
Langmuir, 2020Vibration is a very common process in nature, industry, biology, etc. Thus, whether vibration could induce the formation of nanoscale bubbles in water or not is very important for some chemical or biological reactions. In this paper, we designed a control experiment to simulate the vibration process to explore the production and stability of bulk ...

Generation and Stability of Bulk Nanobubbles
Langmuir, 2017Recently, extremely small bubbles, referred to as nanobubbles, have drawn increased attention due to their novel properties and great potential for various applications. In this study, a novel method for the generation of bulk nanobubbles (BNBs) was introduced, and stability of fabricated BNBs was investigated.

The fate of bulk nanobubbles under gas dissolution
Physical Chemistry Chemical Physics, 2022Depending on the concentration of dissolved gas and the types of amphiphilic substances adsorbed at the gas–liquid interfaces, we report three different situations for the dissolution of bulk nanobubbles: nanobubbles, micelles and large aggregates.

Nanobubble–Nanoparticle Interactions in Bulk Solutions
Langmuir, 2016Nanobubbles form stable colloids in supersaturated solutions. Here we demonstrate the ability of these solutions to interact with Au nanoparticle suspensions. The principle goal was to demonstrate particle modification, similar to froth flotation, and we do indeed see bubble-particle interactions.
