Abstract
Hydrate-based technologies have excellent application potential in gas separation, gas storage, transportation, and seawater desalination, etc. However, the long induction time and the slow formation rate are critical factors affecting the application of hydrate-based technologies. Micro-nano bubbles (MNBs) can dramatically increase the formation rate of hydrates owing to their advantages of providing more nucleation sites, enhancing mass transfer, and increasing the gas–liquid interface and gas solubility. Initially, the review examines key performance MNBs on hydrate formation and dissociation processes. Specifically, a qualitative and quantitative assembly of the formation and residence characteristics of MNBs during hydrate dissociation is conducted. A review of the MNB characterization techniques to identify bubble size, rising velocity, and bubble stability is also included. Moreover, the advantages of MNBs in reinforcing hydrate formation and their internal relationship with the memory effect are summarized. Finally, combining with the current MNBs to reinforce hydrate formation technology, a new technology of gas hydrate formation by MNBs combined with ultrasound is proposed. It is anticipated that the use of MNBs could be a promising sustainable and low-cost hydrate-based technology.

Abstract
(1) The generation of nanobubbles by electrolysis is an interesting method of using electrical energy to form bubble nuclei, effectively creating a multiphase system. For every process, the effectiveness of nanobubble generation by electrolysis depends on various process parameters that impact should be determined. (2) In this work, the electrolytic generation of hydrogen and oxygen bubbles was performed in a self-built setup, in which a Nafion membrane separated two chambers. The generation of bubbles of both gases was investigated using Box–Behnken experimental design. Three independent variables were salt concentration, current density, and electrolysis time, while the dependent variables were Sauter diameters of generated bubbles. An ANOVA analysis and multivariate regression were carried out to propose a statistical and power model of nanobubble size as a process parameter function. (3) The generation of bubbles of hydrogen and oxygen by electrolysis showed that different factors or their combinations determine their size. The results presented in this work proved to be complementary to previous works reported in the literature. (4) The Sauter diameter of bubbles increases with salt concentration and stays constant with increasing current density in investigated range. The proposed correlations allow the Sauter diameters of nanobubbles generated during electrolysis to be predicted.

Abstract
Microfluidic devices providing an accurate delivery of fluids at required rates are of considerable interest, especially for the biomedical field. The progress is limited by the lack of micropumps, which are compact, have high performance, and are compatible with standard microfabrication. This paper describes a micropump based on a new driving principle. The pump contains three membrane actuators operating peristaltically. The actuators are driven by nanobubbles of hydrogen and oxygen, which are generated in the chamber by a series of short voltage pulses of alternating polarity applied to the electrodes. This process guaranties the response time of the actuators to be much shorter than that of any other electrochemical device. The main part of the pump has a size of about 3 mm, which is an order of magnitude smaller in comparison with conventional micropumps. The pump is fabricated in glass and silicon wafers using standard cleanroom processes. The channels are formed in SU-8 photoresist and the membrane is made of SiNx. The channels are sealed by two processes of bonding between SU-8 and SiNx. Functionality of the channels and membranes is demonstrated. A defect of electrodes related to the lift-off fabrication procedure did not allow a demonstration of the pumping process although a flow rate of 1.5 µL/min and dosage accuracy of 0.25 nL are expected. The working characteristics of the pump make it attractive for the use in portable drug delivery systems, but the fabrication technology must be improved.

Abstract
Hypothesis Water electrolysis performed by short (≲5μs) voltage pulses of alternating polarity generates a dense cloud of H2 and O2 nanobubbles. Platinum electrodes turn black in this process, while they behave differently when the polarity is not altered. We prove that the modification of Pt is associated with highly energetic impact of nanobubbles rather than with any electrochemical process. Experiments Nanobubbles are generated by planar Pt or Ti microelectrodes. The process is driven by a series of alternating or single polarity pulses. In the case of Ti electrodes a Pt plate is separated by a gap from the electrodes. Nanoparticles on the surface of platinum are investigated with a scanning electron microscope and elemental composition is analysed using an energy-dispersive X-ray spectrometer. Findings Vigorous formation of Pt nanoparticles with a size of 10 nm is observed when the process is driven by the alternating polarity pulses. The effects of Pt corrosion have different character and cannot explain the phenomenon. Similar nanoparticles are observed when the Pt plate is exposed to a stream of nanobubbles. The process is explained by spontaneous combustion of hydrogen and oxygen nanobubbles on Pt surface. The phenomenon can be used to remove strongly adhered particles from solids.

Abstract
Colloidal nanobubbles occur in gas-saturated aqueous solutions following high power water electrolysis. Here the influence of nanobubble solutions on the self-assembly properties of viral capsid proteins (CP) was investigated. Interestingly, we found that gas solutions were able to trigger the self-assembly of CP of cowpea chlorotic mottle virus (CCMV) in the absence of the viral genome, most likely by acting as a negatively charged template. The process was demonstrated by three distinct techniques, namely, dynamic light scattering (DLS), atomic force microscopy (AFM), and transmission electron microscopy (TEM). Furthermore, nanobubble-induced self-assembly of viral CP was found to depend on protein concentration. Low CP concentrations led to assembly of 18 nm virus-like particles (VLPs), comparable to T = 1 (Casper and Klug triangulation number) virus capsids, whereas high CP concentrations led to 28 nm VLPs (similar to T = 3 capsids). This paves a new route for self-assembly of VLPs.

Abstract
Nanobubbles have been widely studied for their use in water treatments. Conventional methods for producing nanobubbles require significantly high levels of electric power. A system that involves inducing an alternative magnetic field (AMF) in flowing water has been developed, which has relatively low power requirements compared to other methods. Experimental results are presented that indicate nanobubbles are generated by this AMF system. These results include ζ potential measurements in deionized water, light scattering observations, and nanoparticle tracking analysis (NTA) measurements of object size and relative scattering intensity for water containing 5 × 10-4 M CaCO3. The NTA results also suggest the formation of nanobubble-nanoparticle clusters. Finally, an earlier work is reviewed which demonstrated that this AMF treatment led to the removal of tubercles on the inner walls of pipe samples. This prior result is discussed in light of the present evidence of nanobubble formation and a hypothesis is proposed based on the dissolution of CaCO3 as a result of nanobubble-nanoparticle clustering.

Explosion of Microbubbles Generated by the Alternating Polarity Water Electrolysis. ENERGIES 2019. [DOI: 10.3390/en13010020] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/17/2022]
Abstract
Water electrolysis with a fast change of polarity generates a high concentration of bulk nanobubbles containing H 2 and O 2 gases. When this concentration reaches a critical value, a microbubble pops up, which is terminated quickly in an explosion process. In this paper, we provide experimental information on the phenomenon concentrating on the dynamics of exploding microbubble observed from the top and from the side. An initial bubble with a size of 150 μ m expands to a maximum size of 1200 μ m for 150 μ s and then shrinks in the cavitation process. The sound produced by the event is coming from two sources separated in time: exploding bubble and cavitating bubble. The observed dynamics supports expansion of the bubble with steam but not with H 2 and O 2 mixture. A qualitative model of this puzzling phenomenon proposed earlier is refined. It is demonstrated that the pressure and temperature in the initial bubble can be evaluated using only the energy conservation law for which the driving energy is the energy of the combusted gas. The temperature in the bubble reaches 200 ∘ C that shows that the process cannot be ignited by standard combustion, but the surface-assisted spontaneous combustion agrees well with the observations and theoretical estimates. The pressure in the microbubble varies with the size of the merging nanobubbles and is evaluated as 10–20 bar. Large pressure difference between the bubble and liquid drives the bubble expansion, and is the source of the sound produced by the process. Exploding microbubbles are a promising principle to drive fast and strong micropumps for microfluidic and other applications.

Abstract
We investigated the interaction of bulk nanobubbles with cationic liposomes composed of 1,2-dioleoyl- sn-glycero-3-ethylphosphocholine and anionic liposomes assembled from 1-palmitoyl-2-oleoyl- sn-glycero-3-phospho-(1'- rac-glycerol). We employed dynamic light scattering and fluorescence microscopy to investigate both the hydrodynamic and electrophoretic properties of the nanobubble/liposome complexes. These optical techniques permit direct visualization of structural changes as a function of the bubble/liposome ratio. We observed reentrant condensation with cationic liposomes and gas nucleation with anionic liposomes. This is the first report of charge inversion and reentrant condensation of cationic liposomes induced by bulk nanobubbles.

Abstract
Nanobubbles in liquids are mysterious gaseous objects with exceptional stability. They promise a wide range of applications, but their production is not well controlled and localized. Alternating polarity electrolysis of water is a tool that can control the production of bulk nanobubbles in space and time without generating larger bubbles. Using the schlieren technique, the detailed three-dimensional structure of a dense cloud of nanobubbles above the electrodes is visualized. It is demonstrated that the thermal effects produce a different schlieren pattern and have different dynamics. A localized volume enriched with nanobubbles can be separated from the parent cloud and exists on its own. This volume demonstrates buoyancy, from which the concentration of nanobubbles is estimated as 2 × 1018 m-3. This concentration is smaller than that in the parent cloud. Dynamic light scattering shows that the average size of nanobubbles during the process is 60-80 nm. The bubbles are observed 15 minutes after switching off the electrical pulses but their size is shifted to larger values of about 250 nm. Thus, an efficient way to generate and control nanobubbles is proposed.
