Bubble cloud-mediated cavitation for tumor mechanical ablation and effector immune cell deployment [PDF]
Ultrasonics SonochemistryHistotripsy is a cavitation-based tumor ablation technology. To achieve precise cavitation-based ablation requires investigating the cavitation behavior of the bubble cloud and their impact on tumor tissue.

Bubble cloud dynamics in an ultrasound field [PDF]
Journal of Fluid Mechanics, 2019 The dynamics of bubble clouds induced by high-intensity focused ultrasound is investigated in a regime where the cloud size is similar to the ultrasound wavelength. High-speed images show that the cloud is asymmetric; the bubbles nearest the source grow to a larger radius than the distal ones.

Effects of Salinity on Bubble Cloud Characteristics [PDF]
Journal of Marine Science and Engineering, 2017 A laboratory experiment investigates the influence of salinity on the characteristics of bubble clouds in varying saline solutions. Bubble clouds were generated with a water jet. Salinity, surface tension, and water temperature were monitored.

Using space lidar to infer bubble cloud depth on a global scale [PDF]
Scientific ReportsVisible and microwave satellite measurements can provide the global whitecap fraction. The bubble clouds are three-dimensional structures, and a space-based lidar can provide complementary observations of the bubble depth. Here, we use lidar measurements

Bullet Shooting Cloud–Cloud Collision in MIR Bubble N65
The Astrophysical JournalWe report that the formation of the twin-bubble system N65 and N65bis may be caused by the cloud–cloud collision (CCC) from the Bullet Nebula. The blueshifted ^13 CO gas component (N65a [47, 55] km s ^−1 ) is associated with the twin-bubble system, while

Cavitation erosion from single acoustically driven bubbles [PDF]
Ultrasonics SonochemistryAcoustic cavitation is achieved by exciting mechanical vibrations at ultrasonic frequencies, which in turn cause the formation of bubble clouds, followed by flows and emulsification.

The Impact of Aerosol Vertical Distribution on a Deep Convective Cloud
Atmosphere, 2021 This study investigates the effects of aerosol vertical distribution on a deep convective cloud system. We intend to elucidate the mechanisms for aerosols entering the cloud from different heights, and how they affect cloud microphysics and precipitation.
