On the Collapsing Behavior of Cavitation Bubble Clusters [PDF]
The Proceedings of the Fluids engineering conference, 2000 The present paper reports observation results of collapsing cavity bubbles on a two-dimensional foil section by a high-speed video camera, together with impulsive force measurement. Results of numerical simulations of the behavior of bubble cluster corresponding to the above condition are also shown.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic
Advanced Robotics Research, EarlyView.Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Advanced Science, EarlyView.A yolk–shell PTFE‐based composite (YSP) enables tunable, robust hydrophobic–water interfaces for efficient, on‐demand sonocatalytic H2O2 generation and pollutant degradation. ABSTRACT The use of polytetrafluoroethylene (PTFE) particles to promote sonochemical H2O2 production has attracted growing interest, as cavitation bubbles formed at or near their ...

Advanced Science, EarlyView.A glutathione and ultrasound dual‐responsive cerasome achieves sequential co‐delivery of gemcitabine and BMS1166 in tumors. Chemotherapy priming followed by on‐demand PD‐L1 blockade synergistically amplifies anti‐tumor immunity, inhibiting primary tumor growth, distant metastasis and inducing durable immune memory.

The importance of (un)dissolved gases on early-stage cavitation dynamics within an acoustic field
Ultrasonics SonochemistryGas content strongly affects cavitation dynamics; however, most studies rely solely on dissolved gas measurements, overlooking the influence of undissolved bubbles. This study investigates their role by introducing air bubbles (
