Difference between revisions of "Ultrasonication"

During the ultrasonication treatment ultrasound is transmitted through any physical medium by waves that compress and stretch the molecular sppacing of the medium through which it passes<ref name=":0">{{Cite book|author=Hugo Miguel Santos, Carlos Lodeiro, and José-Luis Capelo-Martínez|year=2008|section_title=The Power of Ultrasound|editor=José-Luis Capelo-Martínez|book_title=Ultrasound in Chemistry: Analytical Applications|publisher=Wiley‐VCH Verlag GmbH & Co.

Whenthe negative pressure caused for an ultrasonic wave crossing a liquid is large enough,the distance between the molecules of the liquid exceeds the minimum molecular distance required to hold the liquid intact, and then the liquid breaks down and voids are created. Those voids are the so-called cavitation bubbles<ref name=":0" />.
