The sonochemistry of water based systems is of interest in a large number of areas including pollution remediation, chemical synthesis and safety implications for medical systems. In an attempt to clarify the precise mechanism of aqueous sonochemistry. measurements of radical production as well as monitoring sonoluminescence emission and recording acoustic emission spectra have indicated how additives affect the cavitation field and also demonstrated large differences in the nature of both cavitation predicts and the cavitation field when using ultrasound with two different ultrasound set-ups; a 20 kHz horn and a 515 kHz emitting transducer. A possible model to explain some of these results has been proposed suggesting that the type of cavitation is different in the two situations in terms of the proportion of stable and transient bubbles that exist. Applications of the methods to characterising ultrasonic dental instruments has shown a detailed dependence of cavitation on the design and properties of the tip.
