Ultrasonication  

Definition

  • The irradiation of a liquid sample with ultrasonic (>20 kHz) waves resulting in agitation (Matportal/materialsMine), (https://matportal.org/ontologies/MM/?p=classes&conceptid=http%3A%2F%2Fmaterialsmine.org%2Fns%2FUltra-sonication&jump_to_nav=true)
  • The irradiation of a liquid sample with ultrasonic (>20 kHz) waves resulting in agitation. Sound waves propagate into the liquid media result in alternating high-pressure (compression) and low-pressure (rarefaction) cycles. During rarefaction, high-intensity sonic waves create small vacuum bubbles or voids in the liquid, which then collapse violently (cavitation) during compression, creating very high local temperatures.
