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.

High Shear Mixing with Ultrasonics
High shear mixers apply high shear forces into liquids and slurries in order to provide the uniform dispersing, blending, and emulsification of two or more liquid-solid or liquid-liquid phases. Ultrasonication generates high shear forces via acoustic cavitation, which occurs…

Ultrasonic Disintegration: Wetting, Dissolving, Dispersing
Ultrasonic integrators are widely used to wet, disperse or dissolve particles and powders into liquids. High-performance ultrasonicators create intense shear forces, which break and shatter aggregates, agglomerates and primary particles to microscopic or nano size. The uniform particle processing…
