Facilitated mechanisms, emulsion liquid

Ultrasound is known to facilitate emulsification in biphasic systems [76] with benefits including smaller drop sizes down to 0.3 xm [77], lower energy consumption and more stable emulsions that are less polydispersed than conventional mechanical techniques [78]. Cavi-tational processes occur preferentially at the phase boundary [78, 79] causing intensive shock waves in the surrounding Kquid and the formation of liquid jets of high velocity [80]. These mechanical forces act to divide droplets again and again...
