Utrasonic topic: "What is Sonochemistry?"
Sonochemistry is the application of ultrasound to chemical reactions and processes. SOnication is used to intensify chemical reactions such as synthesis and catalysis. When intense ultrasound waves are couples into liquids, the phenomenon of acoustic cavitation occurs. Ultrasonic cavitation improves mass transfer between reactants, speeds up the reaction and/or allows to change the chemicals pathway.
