The material, as a sonocatalyst, can effectively degrade bisphenol A (BPA) in water when activated by ultrasound, and its synergistic effect with peroxymonosulfate (PMS) can further enhance the degradation effect. CuO/CuBi₂O₄ composite with a 60% composite ratio (CC-60) exhibited the optimal sonocatalytic performance, and the US/CC-60/PMS system with PMS added exhibited more outstanding sonocatalytic activity than the original system. In optimal experimental conditions, the removal rate of BPA was 98.48 ± 0.39%. Trapping experiments and in-situ X-ray photoelectron spectroscopy results confirmed the formation of an S-scheme heterojunction between CuO and CuBi₂O₄. This heterojunction effectively promoted electron-hole pair separation, significantly enhanced the ultrasonic catalytic performance of CuBi₂O₄. Furthermore, within the US/CC-60/PMS system, BPA was efficiently degraded with a rate constant of 0.219 min⁻¹, which substantially exceeded those of US/PMS (0.008 min⁻¹) and US/CC-60 (0.019 min⁻¹) system. The results demonstrated that the synergistic interaction among the system components significantly enhanced sonocatalytic activity. CC-60 has shown excellent stability and reusability in the application process, and still maintains a high BPA removal rate in actual water. It also has a wide range of pH and anion tolerance, demonstrating excellent development potential.

To address this issue and reveal the underlying mechanisms, a rotational ultrasonic atomization platform was developed. The effects of ultrasonic power, liquid viscosity, horn geometry, rotation speed, and initial momentum on atomization behavior were investigated using high-speed imaging. For low-viscosity liquids, increasing ultrasonic power elevated the Weber number, widened the spray angle from 63 degrees to 142 degrees, and shortened the atomization incubation period from 10.86 s to 8.15 s. For high-viscosity liquids, viscous damping suppressed the capillary wave pathway, making cavitation the dominant mechanism. Driven by the secondary Bjerknes force, cavitation bubbles bridged into branched, neural-network-like clusters. Their collective collapse overcame the viscous dissipation barrier, providing experimental validation for Boguslavskii’s hypothesis. A critical rotation threshold of 60 revolutions per minute was identified. Below this threshold, acoustic pinning confined the liquid on the horn end-face; above it, centrifugal force forcibly thinned the liquid film, triggering atomization. Furthermore, horn geometry determined the atomization onset location, while increased initial momentum accelerated initiation. Experiments on Sn-58Bi melt verified that coupling optimized horn geometry with a centrifugal force field effectively overcomes the surface energy barrier. Based on these findings, a six-stage atomization model is proposed. The capillary wave mechanism primarily achieves initial film thinning by stripping large droplets, while cavitation dominates fine fragmentation.

This study constructed an ultrasonic coupling lateral column leaching system to simulate the in-situ leaching process. The effects of ultrasonic parameters (probe position, power and mode) on the lateral seepage rate and leaching efficiency were investigated. Influence of thermal effect and ultrasonic effect on leaching was distinguished. The results indicate that applying ultrasound in the middle position of the ore body achieves the higher leaching efficiency and lateral seepage rate compared to other positions. Under an optimized pulsed mode (360 W, 5 min on/5 min off, 5 h), the leaching efficiency of rare earth elements (REEs) reached 94.4 %, representing a 9 % increase over the temperature control and a 22 % increase over conventional leaching. Concurrently, the average lateral seepage rate increased by 0.317 mL/min, and the leaching duration was shortened by 37.8 %. Although the leaching efficiency of the 5/15 mode is slightly lower, its superior energy efficiency is more attractive in industry. Characterization results revealed that ultrasound induced particle benign refinement, surface erosion, and pore development, increasing the specific surface area by 42 %. Kinetic analysis confirmed that ultrasound shifted the rate-limiting step from external diffusion control to chemical reaction control, effectively eliminating mass transfer resistance.

Under optimized conditions, ultrasound-enhanced degumming with phospholipase A₁ (PLA₁, ultrasound: 200 W, 50 °C, 2 h) and with Purifine® 3G (ultrasound: 200 W, 40 °C, 1 h) each achieved &gt; 98.6 % degumming efficiency, representing an increase of up to 4.55 percentage points compared with conventional enzymatic degumming, and reduced residual phosphorus in degummed oil to below 1.6 mg/kg.
