Here, we found that sononeoperfusion-a new effect of tumor perfusion enhancement induced by low mechanical index ultrasound stimulated microbubble cavitation (USMC)-ameliorated tumor tissue oxygenation and induced tumor vascular normalization (TVN). This TVN might be associated with the down-regulation of hypoxia-inducible factor 1-alpha (HIF-1α) and vascular endothelial growth factor (VEGF) within tumors. Moreover, the sononeoperfusion effect reduced the accumulation of immunosuppressive cells, such as regulatory T cells (Tregs), myeloid-derived suppressor cells (MDSCs) and M2-like tumor-associated macrophages (M2-TAMs), and decreased the production of immune inhibitory factors like transforming growth factor-β1 (TGF-β1), interleukin 10 (IL-10), chemoattractant chemokines CC-chemokine ligand 22 (CCL22), CCL28, adenosine and lactate within tumors. Notably, flow cytometry analysis revealed that sononeoperfusion not only increased the percentage of tumor infiltrating-CD8<sup>+</sup> T cells, but also promoted the generation of interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) by these cells. Furthermore, the improved immune TME by sononeoperfusion effect sensitized anti-PD-L1 treatment both in MC38 colon cancer and Lewis lung carcinoma mice, resulting in tumor regression and prolonged survival. Mechanically, the enhanced efficacy of combination therapy was mainly based on promoting the infiltration and function of CD8<sup>+</sup> T cells within tumors.

Under ultrasound, the crystal form and crystal morphology remained well maintained. The results of particle size and size distribution suggested that ultrasound reduced the mean sizes by improving the nucleation process and breaking up large particles. Additionally, the presence of ultrasound in continuous experiments was capable of inducing nucleation and the crystal products collected had a suitable distribution. Integrating ultrasound into the beginning of the continuous crystallization process can be an alternative to the seeding technique. The increasing sonication power did not reduce the induction time substantially. This indicated that a rational sonication condition should balance the overall process efficiency and energy consumption. The findings from batch and continuous experiments indicate that ultrasound could intensify industrial crystallization of the aromatic amine.

Due to the very small variation of the total energy between different configurations, the probability of formation of a mixed phase was found to be very high in such a way that the more mixed was the phase, the more stable it was. A relevant fact was the noticed quasi-systematic ionic exchange made possible by the very short reaction times and high energy offered by the ultrasonic waves.

This study first delves into the effect of ultrasonic parameters on bubble dynamic behaviors and associated mechanisms, subsequently further analyzing the forces acting on bubbles through the constructed force model. The findings suggest that although growth force serves as the significant resistance, the primary Bjerknes force dominates the rapid detachment of bubbles. The secondary Bjerknes force results in the bubble only sliding along the bottom wall rather than lifting off. Furthermore, the elevated ultrasonic pressure amplitude resulting from augmenting ultrasonic power induces a substantial increase in the critical detachment diameter and growth rate by 55.49 % and 59.42 %, respectively. The enhanced primary Bjerknes force, attributed to the rise in ultrasonic frequency, leads to a 71.42 % increase in sliding velocity and a 46.45 % reduction in growth time.
