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.

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 ...

Bulk Nanobubbles Fabricated by Repeated Compression of Microbubbles
Langmuir, 2019Nanobubbles (NBs), given its extraordinary properties, have drawn keen attention in the field of nanotechnology worldwide. However, compared to that of surface NBs, generation of stable bulk NBs remains an arduous task with the prevailing method. In this study, we developed a pressure-driven method to prepare bulk NBs by repeatedly compressing sulfur ...

Interaction of Bulk Nanobubbles (Ultrafine Bubbles) with a Solid Surface
Langmuir, 2021The experimental results [Kanematsu, W. Chem. Eng. Sci. 2020, 219, 115594] on the temporal variations of number concentrations of bulk nanobubbles (ultrafine bubbles) in contact with polymer materials are theoretically analyzed based on the dynamic equilibrium model of bulk nanobubbles partly covered with hydrophobic materials (impurities).

Coalescence Conditions for Bulk Nanobubbles
Technical Physics Letters, 2020The coalescence of two nanobubbles with substantially different radii is considered. Studies of this problem have practical significance, because coalescence is an undesirable process (the nanobubbles lose their unique properties after enlargement). An energy-based approach is used with a simplified model of charged nanobubbles to demonstrate that bulk

Evolution of Bulk Nanobubbles under Different Freezing Conditions
Langmuir, 2023The freezing process of aqueous solutions plays a crucial role in various applications including cryopreservation, glaciers, and frozen materials. However, less research has focused on the influence of nanoscale gas bubble formation or collapse in water during freezing, which may significantly impact the formation of ice crystals. Herein, we report for
