| Abstract Scope |
Acoustic cavitation in the ultrasonic regime is a transient and intriguing phenomenon that is predominantly affected by liquid properties and the applied acoustic pressure. Bubble implosion produces localized shock waves and high-speed liquid jets that have been proven useful in various processes, especially with ultrasound. However, many fundamental issues during cavitation remain unresolved due to difficulties in real-time, high-fidelity observation of the ultra-high-speed collapse mechanism at sub-micron spatial and temporal resolutions. Here we report the complementary synchrotron and X-ray free-electron laser (XFEL) in situ MHz microscopy studies of ultrasonic cavitation dynamics in different liquids and their interaction with microparticles. The result shows, for the first time, the dramatic differences in cavitation characteristics from nucleation, oscillation, and collapse of an acoustic bubble at different liquid viscosities and at near-pressure field. These new key findings are crucial in developing ultrasound-enabled technologies for particle refinement and efficient processing of nanomaterials. |
