In recent years,significant increases in waste processing and material engineering have been seen by using advanced oxidation *** treatment results and energy yields of these processes are largely determined by the generation and retention of reactive oxygen species(ROS).However,increasing the amount of ROS remains a key challenge because of the unavailability of performance-and energy-efficient *** this study,plasma electrolysis,ultrasound,and plasma electrolysis combined with ultrasound were used to treat dimethyl sulfoxide(DMSO)solutions,and the results showed that the two methods can synergistically convert filament discharge into spark discharge,and the conversion of the discharge mode can significantly increase the concentration of OH radicals and effectively improve the efficiency of DMSO *** verified the rationality of the results by analyzing the mass transfer path of ROS based on the reaction coefficients and found that the OH radicals in aqueous solution were mainly derived from the decomposition of hydrogen *** findings indicated that the synergistic action of plasma electrolysis and ultrasound can enhance the production of chemically reactive species,and provide new insights and guiding principles for the future translation of this combined strategy into real-life *** results demonstrated that the synergistic strategy of ultrasound and plasma electrolysis is feasible in the switching mode and increasing the ROS,and may open new routes for materials engineering and pollutant degradation.

Background, Motivation and Objective With the development of economy, the demand for oil and other energy sources is growing. Especially over the past decade, the demand for oil and natural gas is increasing with the rate of 1.8% per year. Due to the reduction of oil resources in the world, the exploitation of heavy oil, extra-heavy oil and the high pour point oil is becoming more and more important. However, the high-density, high pour point, and poor mobility characteristics of the extra-heavy oil and the high pour point oil make the exploration difficult. Therefore, how to reduce the viscosity of the extra-heavy oil and reduce the pour point of high pour point oil, so that improving their liquidity at room temperature, is of great important for exploration and transportation. Ultrasonic viscosity reduction is a physical viscosity reduction technique, using the physical effect, such as high temperature, high pressure and vibration generated by acoustic cavitation to accelerate or change the chemical reactions. Using the high-power ultrasonic horn to generate acoustic energy(mainly the ultrasonic cavitation, thermal effect and mechanical effect) to reduce the viscosity of heavy oil is a effective method. The feasibility of this technique in experimental has been already verified, but the researches are mostly limited in the laboratory. The transducer engineers have done a lot of research work and develop a number of design theory about theoretical calculation and engineering design on the high-power sandwich piezoelectric ultrasonic horn. But until now, the high-power ultrasonic horn used in the production line is still immature. Low temperature resistance, small-scale of batch processing and low working intensity are the main restrictions. Statement of Contribution/Methods Based on the basic principle of the sandwich piezoelectric transducer, a high-power ultrasonic horn which can be used for viscosity reduction of heavy oil and pour point reduction of crude oil w
