This paper investigates the impact of radiative and mechanical feedback from O-type stars on their parent molecular clouds triggering formation future generation stars. We study infrared bubble S111 created by embedded massive stellar cluster G316.80-0.05. A significant fraction gas in shells due to compression ambient medium expanding bubbles is photodissociated radiation. The kinematics are t...

The calculation of the equilibrium constants K of the sonolysis reactions of CO2 into CO and O atom, the recombination of O atoms into O2 and the formation of H2O starting with H and O atoms, has been studied by means of statistical thermodynamic. The constants have been calculated at 300 kHz versus the pressure and the temperature according to the extreme conditions expected in a cavitation bu...

Atomization and fountain formation is a well-known phenomenon that occurs when a focused ultrasound wave in liquid encounters an air interface. High intensity focused ultrasound (HIFU) has been shown to fractionate a tissue into submicron-sized fragments in a process termed boiling histotripsy, wherein the focused ultrasound wave superheats the tissue at the focus, producing a millimetre-sized ...
