Summary: The investigation of cavitation activity during ultrasonic treatment of magnesium particles revealed that the characteristics of cavitation zone may vary depending on the concentration of magnesium particles in the suspension and the nature of the medium. Scanning electron microscopy, X-ray diffraction analysis, and thermal analysis were used to characterize ultrasonically treated magnesium particles, showing the presence of magnesium hydroxide and magnesium hydride in different dispersed media. Furthermore, the incorporation of magnesium hydride in the magnesium matrix was found to be possible by adjusting the conditions of ultrasonic treatment. Additionally, the reactivity of magnesium was confirmed by measuring cavitation activity in various dispersed media.

Summary: Broad-band noise is used to monitor cavitation activity in various applications, but its origin is still debated. This review discusses two models for the mechanism of broad-band noise: acoustic emissions from chaotically pulsating bubbles and acoustic emissions from bubbles with temporal fluctuation in number. The latter mechanism may be dominant and further studies are needed on bubble cluster dynamics and bubble-bubble interaction in the broad-band noise, especially at low ultrasonic frequencies.

Summary: A theoretical model is proposed to describe the pulsation, translation, and deformation of twin bubbles in an ultrasound field based on potential flow and perturbation theory. The amplitudes of bubbles' oscillations are found to be dependent on initial translation velocities, with the periods of oscillations decreasing as initial translation velocities increase. The interaction between bubbles causes the instable area in the phase space to enlarge.

Summary: The study revealed that the shape of micromotors has a significant impact on propulsion speed at low fuel concentrations, with the concave Pt-coated micromotor moving slower and the bubble growth being slower on its surface compared to the convex Pt-coated micromotor. In the multi-bubble propulsion mode at high fuel concentrations, increasing fuel concentration did not enhance maximum propulsion speed, suggesting a more is less phenomenon in the interaction among bubbles.

Summary: This study experimentally investigates the complex interaction between underwater explosion (UNDEX) bubbles and a free surface. The dependence of the associated physics on the dimensionless detonation depth is revealed. Four typical bubble behavior patterns are identified and a critical value is found for ignoring the effects of the free surface on UNDEX bubbles. Good agreements are obtained with a unified theory for bubble dynamics. The dependence of pressure signals on the detonation depth is also investigated.

Summary: This study investigates the behavior of cavitation bubbles in a liquid confined in an elastic sealed vessel driven by ultrasound. The model assumes that the pressure acting on the sealed vessel due to bubble pulsations is proportional to the total volume change of bubbles. The simulations show that the pulsation of a single bubble can be significantly suppressed in the sealed vessel, and the pulsation of two matched bubbles can be further suppressed. However, when two mismatched bubbles have the same ambient radii, an interesting breathing phenomenon occurs, weakening the suppression effect and allowing the maximum radii of the bubbles to be larger than that of a single bubble or two matched bubbles in the sealed vessel. Additionally, for two mismatched bubbles with different ambient radii, the smaller one in the sealed vessel can pulsate as strongly as or even stronger than a single bubble in an open vessel under certain parameters.

Summary: In our previous study, we proposed a new model for single bubble dynamics that considers the effect of bulk viscosity. In this study, we conducted experiments to test this model using a 30% (v/v) glycerol-water mixture. The results showed that the calculated bubble dynamics were not significantly affected by bulk viscosity under the experimental conditions. However, there was a noticeable delay in the first rebound when bulk viscosity was taken into account. The sonoluminescence intensities were also compared between the two models, but no significant difference was observed, confirming the negligible effect of bulk viscosity in this condition.

Summary: Hempseed protein isolate (HPI) can be improved in functionality, such as solubility, emulsifying, and foaming properties, through ultrasonic-assisted extraction. The enhanced functionality is attributed to the changes in protein structure, including increased hydrophobicity and decreased particle size of protein aggregates. Prolonged high-power ultrasound exposure may negatively affect the functional properties of HPI.

Summary: The effect of nanobubbles (NBs) on liquid surface tension was studied using three different methods, namely pendant drop (PD), Wilhelmy, and du Nou'y methods, over a wide range of bulk NBs (BNBs) concentrations. In all three methods, the surface tension decreased proportionally with the BNBs concentration, although the proportional constant varied. This behavior was attributed to the surface excess of BNBs at the gas-liquid or solid-liquid interface. The decrease in surface tension was observed to be gradual in the PD method, taking several hundreds of seconds, while it was instant in the Wilhelmy and du Nou'y methods, likely due to electrostatic forces at the solid-liquid interface.

Summary: It has been experimentally observed that oxidation and reduction reactions occur in ultrasound-assisted aqueous solutions without any additives. Numerical simulations show that reducing agents produced from air or argon bubbles in water under ultrasound include H, H-2, HO2, NO, HNO2, and sometimes H2O2. These agents can reduce metal ions to form metal nanoparticles in strongly alkaline solutions. Superoxide anion (O-2(-)) and hydrated electrons (e(-)aq) may also play a role in the sonochemical reduction of solutes, especially in strongly alkaline solutions. The influence of ultrasonic frequency on the production of H atoms from cavitation bubbles is also discussed.

Summary: The degradation of paracetamol was investigated under various single-frequency and dual-frequency ultrasonic irradiations. The optimal degradation rate was achieved at 850 kHz in both single and dual-frequency ultrasonic irradiation. Dual-frequency ultrasound showed a synergistic effect in enhancing pollutant degradation. The degradation was mainly dependent on the yield of HO center dot, but frequencies higher than 500 kHz exhibited enhanced degradation due to improved mass transfer.

Summary: By comparing the permselectivities and Cl- conductivities of non-crosslinked RG-AEMs with different cationic headgroups, this study found that the chemistry of the headgroup can modify the balance between permselectivity and conductivity in RG-AEMs. Higher water content and higher ion exchange capacity led to lower permselectivities. The addition of ionic crosslinking further improved the permselectivity of DMI-based RG-AEMs. These findings indicate the potential of high ion exchange capacity AEMs with imidazolium-type headgroups and optimal ionic crosslinking, calling for more research on their comparison with non-RG analogues.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions.
