Summary: High-power microwave beams used for heating and current drive in magnetically confined fusion plasmas can be broadened significantly by plasma turbulence, negatively impacting the machine's efficiency. This study aims to develop an empirical model to estimate beam broadening by turbulence without the need for computationally expensive full-wave simulations. The dependencies of beam broadening on plasma and beam parameters are investigated, and it is found that the dependence on certain parameters is inseparable. An empirical formula is obtained for fusion-relevant scenarios, enabling quick prediction of the effect in microseconds.

Summary: This paper presents a sustainable and efficient protocol for the conversion of levulinic acid into N-substituted pyrrolidones using microwave-assisted catalytic reactions. The authors optimized the reaction conditions using tailor-made catalysts supported on highly mesoporous silica or titania-doped HMS, achieving good-to-excellent yields. Furthermore, they successfully scaled up the reaction using a microwave-assisted flow reactor and green solvents. This new method shows promise for industrial applications, while minimizing the use of toxic organic solvents.

Summary: In this study, cavitation characteristics and acoustic pressure of a thin liquid Ga-In alloy were investigated using high speed photography, numerical simulation, and bubble dynamics calculation. The results showed that the acoustic pressure inside the thin liquid layer exhibited alternating positive and negative characteristics, leading to bubble growth and collapse. Cavitation was divided into violent and weak stages, with violent cavitation lasting for several hundreds of acoustic periods and having higher bubble intensity. High cavitation intensities were observed at high ultrasonication power and when using Q235B alloy.

Summary: Underwater plasma has been recognized as an environmentally friendly alternative to conventional chemicals in wastewater treatment. However, its practical application is challenging. In this study, a novel process named ACAP was proposed to stabilize plasma generation and enlarge the processing region. Results showed that injecting argon into the ACAP reactor significantly enhanced the degradation efficiency of wastewater pollutants.

Summary: Ultrasound degrades legacy per- and polyfluoroalkyl substances (PFAS) via thermolysis at the interface of cavitation bubbles. This study compared the ultrasonic treatment of n:2 fluorotelomer sulfonates (FTSAs) with varying chain lengths (n = 4, 6, 8) to understand the effect of size on degradation kinetics and mechanism. The results showed that ultrasound efficiently degrades FTSA of different sizes and may have the potential to treat other classes of polyfluoroalkyl substances.

Summary: This study focused on the application of ultrasonic cavitation peening on metal specimens. By using a V-shaped traveling wave piezoelectric vibrating system, an even performance on a cylindrical surface could be achieved upon single treatment, with emphasis on the effects of tangential vibration on cavitation intensity and distribution. Through numerical simulation and experimentation, it was found that after ultrasonic cavitation peening treatment, the micro hardness of cylindrical workpiece surfaces significantly increased.

Summary: Combining hydrodynamic cavitation with other advanced oxidation methods can effectively improve the degradation efficiency of Rhodamine B dye. The combination of hydrodynamic cavitation and plasma oxidation shows the best degradation effect with a high degradation rate and a synergistic effect. Compared with other combination modes, the combined effect of hydrodynamic cavitation and plasma oxidation has higher degradation efficiency and lower operation cost, making it more suitable for large-scale application.

Summary: Microwave is an electromagnetic wave of specific frequencies (300 MHz-3000 GHz), while ultrasonic is a mechanical wave of specific frequencies. The combination of ultrasonic and microwave technology has been used as an improvement technique in food processing. This paper provides an overview of the principles and characteristics of ultrasonic- and microwave-assisted food processing techniques, particularly their combinations, equipment design, and applications in various food processing methods such as thawing, drying, frying, extraction, and sterilization. The synergy of microwave heating and the cavitation effect of ultrasonic improves processing efficiency and damages the cell structure of the material, while reducing nutrient degradation and energy consumption.
