Dissolved gas and ultrasonic cavitation – A review
Ultrasonics Sonochemistry, 2013 The physics and chemistry of nonlinearly oscillating acoustic cavitation bubbles are strongly influenced by the dissolved gas in the surrounding liquid. Changing the gas alters among others the luminescence spectrum, and the radical production of the collapsing bubbles.

Ultrasonic cavitation in thin liquid layers
Ultrasonics Sonochemistry, 2005 The generation of ultrasonic cavitation in a thin liquid layer trapped between a large radiating surface and a hard reflector and bounded laterally by a gas-liquid interface is investigated. The theoretical analysis predicts that a large amplification of the acoustical pressure is obtained with this configuration.
