Utrasonic topic: "Ultrasonication: Applications and Benefits"
Ultrasonication is the application of intense ultrasound waves into liquids and slurries. The acoustic cavitation generated by intense sonication creates energy-dense conditions such as high pressure and temperature differentials as well as high shear forces and turbulences. Those forces agitate particles, break droplets and disrupt cells causing homogenisation, dispersion, emulsification and extraction effects.

Polyols are synthetic esters produced mainly via a transesterification of triglycerides from vegetable oils or animal fats. These polyols are raw material for the production of polyurethans, biolubricants and other cemicals. Ultrasonication is used to enhance transesterification reactions by applying…
