Ionic liquids have favorable intrinsic properties that make them of interest as solvents for various chemical reactions. The same properties that make the liquids effective solvents also make them interesting liquids for studies involving sonochemistry, acoustic cavitation, and sonoluminescence. Recent interest in using ultrasound to accelerate chemical reactions conducted in ionic liquids nece...

Ultrasound is a well-established method for particle size reduction in dispersions and emulsions. Ultrasonic processors are used in the generation of nano-size material slurries, dispersions and emulsions because of the potential in the deagglomeration and the reduction of primaries. These are the mechanical effects of ultrasonic cavitation. Ultrasound can also be used to influence chemical rea...

Sonoluminescence is the intriguing phenomenon of strong light flashes from tiny bubbles in a liquid [1]. These bubbles are driven by an ultrasonic wave and need to be filled with noble gas atoms. The spectrum of the emitted light corresponds to very high temperatures [2] and hints the presence of an hot opaque plasma core [3]. Although sonoluminescence has been studied extensively, the origin o...
