Ultrasonic 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.

Ultrasonically Assisted Fermentation for Bioethanol Production
Ultrasonically-assisted fermentation can enhance bioethanol production by promoting the breakdown of complex carbohydrates into simpler sugars, making them more readily available for yeast to convert into ethanol. Simultaneously, sonication also improves the efficiency of yeast cell wall permeability, allowing for…
