Summary: This study numerically simulated the energy balance related to a stable bubble irradiated by a dual-frequency field. The results showed that pressure forces were the main energetic input during the bubble oscillation lifetime, while heat transfer by diffusion and enthalpy loss due to water condensation were the main energetic losses. High rates of condensation of water molecules and low amounts of accumulated energy inside the bubble volume were identified as key factors preventing the achievement of sonochemical activity.

Summary: This study synthesized epoxidized natural rubber (ENR) using a sonochemical method, with acoustic cavitation employed as a replacement for heat and agitation in the epoxidation reaction. The effects of reaction time and temperature on the epoxidation degree (EPD) were examined. The results showed that, at shorter reaction times, the EPD increased with increasing reaction time, while at longer reaction times, the EPD depended on both reaction time and temperature. The highest EPD was achieved using the sonochemical method at a reaction temperature of 30 degrees C for 60 minutes, equivalent to the EPD achieved using the conventional method at a higher temperature and longer reaction time.

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: The use of sonication effectively decontaminates Mg-based materials, removing the carbon layer promoting corrosion in UNGG cladding. However, it also leads to a continuous surface recontamination process due to re-adsorption of uranyl cations, which can be avoided by optimizing treatment duration.

Summary: The efficient and cost-effective removal of polycyclic aromatic hydrocarbons (PAHs) can be achieved through combined cavitation and oxidation processes. Various methods such as sonochemistry, biodegradation, photodegradation, Fenton oxidation, ozone oxidation, and photochemical oxidation have been reviewed for PAH removal. Factors controlling cavitation under sonochemical irradiation, the performance of different reactors, and the influence of gas sources on degradation efficiency have been discussed. Further research has shown that the reduction of PAHs can be significantly improved under certain conditions and with the use of specific gases.

Summary: Dissolved gases significantly affect acoustic cavitation and sonochemical oxidation reactions, but little research has been done on the changes in dissolved gases and the resultant changes in sonochemical oxidation. This study continuously measured the dissolved oxygen (DO) concentration during ultrasonic irradiation in different gas modes and quantified the changes in sonochemical oxidation. The results showed that the initial gas conditions and active gas exchange with the atmosphere influenced the DO concentration and the reaction constants. The mass-transfer and ultrasonic-degassing coefficients were also calculated.

Summary: This study investigates the cavitation noise characteristics of centrifugal pumps using a combination of test and simulation. The numerical simulation based on spherical cavity radiation theory and the acoustic finite element method is validated with a multi-field synchronized test-rig. The results show that the numerical simulation is consistent and reliable. The development of cavitation has a significant impact on the flow field, especially in the strong vorticity regions, and the vortex promotes the formation of cavitation. The acoustic power on the blade suction-side is greater than the pressure-side, and the pulsating radiated noise of cavitation volume becomes the primary noise source as the cavitation number decreases.

Summary: Sonochemistry utilizes ultrasound to generate reactive radicals, offering a green alternative for hydrogen production, wastewater treatment, and chemical synthesis. Conventional sonochemical reactors often have design limitations resulting in low efficacy and slow reaction kinetics. A novel reactor design was constructed, creating intense localized high pressure amplitudes capable of spontaneous cavitation, leading to significantly higher hydroxyl radicals production rate and sonochemical efficiency.

Summary: Sphere-pac fuel is an alternative nuclear fuel technology that uses microspheres to fill the cladding tube instead of conventional single-size fuel pellets, allowing for adjustable packing density and porosity. In this study, a flow-focusing droplet generator made from stainless steel was used to investigate the size and size distribution of ceria microspheres, which were used as a surrogate for plutonium. The characterization of the ceria microspheres was done using SEM, XRD, FTIR, and BET analyses. Precise control of the size of monodisperse microspheres was achieved using different flow-focusing droplet generators, with a size range of 498-2888 μm and a coefficient of variation of less than 2%.

Summary: This study investigated a scalable oil extraction strategy using a hybrid approach of soaking pretreatment and ultrasound extraction. The combination of pretreatment and ultrasound-assisted extraction reduced energy consumption and treatment time compared to ultrasound alone. The maximum oil extraction yield of 99.1% and treatment time of 4 minutes make this combined approach a scalable method for continuous oil extraction. The required processing capacity for an ultrasound plant processing 1 ton of raw material per day is 2.777 kg/batch, significantly higher than ultrasound without pretreatment and Soxhlet method.

Summary: This study investigates the effects of various parameters on KLa in reactive and non-reactive liquid-liquid extraction systems, including capillary size, shape, flow ratio, presence of additives, and presence of wall film. Empirical correlations are developed based on literature data for a constant liquid flow ratio of 1, relating the Sherwood number (Sh), Reynolds number (Re), capillary number (Ca), and Schmidt number (Sc) for different ranges of Re. The concept of j-factor for micro-channels is introduced and named as the Pandit-Kunzru-Ganguli analogy. New dimensionless numbers, namely the Pandit number (Pa), Ganguli number (Gn), and Kunzru number (Ku) are introduced. The study also suggests future research directions based on the findings.

Summary: We have prepared a commercially viable Deep Eutectic Solvent (DES) based on Choline Chloride-Urea-copper acetate for the first time. It mediates the homocoupling of terminal alkynes, using air as an oxidant. Water is the only by-product of the entire process. The method avoids ligands, bases, oxidants, and costly palladium catalysts, making the process greener than ever. The DES can be reused at least three times without significantly affecting the reaction yield. The key features of the protocol, including ambient reaction temperatures, lesser use of conventional organic solvents, higher yields, and easy product isolation, qualify the process as a green one.

Summary: A mild, convenient, and green route for synthesizing benzoxazole derivatives using o-aminocardanol and aromatic aldehydes in the presence of Indion 190 resin as a heterogeneous catalyst was developed. The reaction was conducted under ultrasound irradiation and a greener solvent, resulting in good yields of the desired products. The study demonstrated the tolerance of the reaction towards various electron-donating, electron-withdrawing, polyaromatic, and heterocyclic aldehydes. Additionally, the heterogeneous catalyst Indion 190 resin could be recovered and reused several times without significant loss of its catalytic activity.
