The extraction process was assisted by sonication which is based on the sonochemical phenomenon associated with acoustic cavitation
 that helps the disruption of cell walls and facilitate the release of contents .
This type of cavitation is known as acoustic cavitation
, (Franc, 2004).
As the bubbles violently collapse, they release tiny shock waves, a phenomenon called acoustic cavitation
Surface acoustic cavitation
understood via nanosecond electrochemistry.
It is generally accepted that ultrasonic irradiation affects chemical reactions through acoustic cavitation
in the reaction medium [1, 2].
This acoustic cavitation
can produce intra-bubble temperatures approaching l0,000[degrees]C.
Researchers knew then that collapsing bubbles could create high temperatures and pressures, a phenomenon known as acoustic cavitation
While the chemical effects of acoustic cavitation
