Effect of Stable and Transient Cavitation on Ultrasonic Degassing of Al Alloy

Metals
Cavitation is a critical phenomenon for improving melt quality in casting processes by reducing hydrogen porosity, and it can be classified into two major types based on bubble dynamics, stable and transient cavitation.

Observations and scaling of travelling bubble cavitation [PDF]

, 1995
Recent observations of growing and collapsing bubbles in flows over axisymmetric headforms have revealed the complexity of the ‘micro-fluid-mechanics’ associated with these bubbles (van der Meulen & van Renesse 1989; Briancon-Marjollet et al.

Copper and Iron‐Based Metal‐Organic Frameworks for Synergistic Cancer Phototherapies: Recent Advances, Challenges, and Future Prospects

Advanced Therapeutics, EarlyView.
The graphical abstract illustrates the combined effect of PTT and PDT using metal‐organic frameworks (MOFs) in a cancer treatment model. Tumor‐bearing mice are irradiated with different laser lights, which activate the MOF nanoparticles within cancer cells. The MOFs produce reactive oxygen species through PDT, while PTT elevates the temperature to kill
