The total annual production of synthetic dye is more than 7× 105 tons. Annually, through
only textile waste effluents, around one thousand tons of non-biodegradable textile dyes are …

Acoustic cavitation in a liquid medium generates several physical and chemical effects. The
oscillation and collapse of cavitation bubbles, driven at low ultrasonic frequencies (eg, 20 …

Bubbles in liquids, soft and squeezy objects made of gas and vapour, yet so strong as to
destroy any material and so mysterious as at times turning into tiny light bulbs, are the topic …

Ultrasound refers to sound waves above the human hearing range. The physical effects of
ultrasound include the turbulence associated with cavitational bubble collapse, microjetting …

The study of the interaction of bubbles with shock waves and ultrasound is sometimes
termed 'acoustic cavitation'. It is of importance in many biomedical applications where sound …

A number of acoustic and fluid-dynamic phenomena appear in ultrasonic cleaning baths
and contribute to physical cleaning of immersed surfaces. Propagation and repeated …

A laboratory filtration plant for drinking water treatment is constructed to study the conditions
for purely mechanical in situ cleaning of fouled polymeric membranes by the application of …

Smart materials can respond to stimuli and adapt their responses based on external cues
from their environments. Such behavior requires a way to transport energy efficiently and …

A new phenomenon in ultrasonic cavitation field is reported. Cavitation bubbles are
observed to self-arrange in a cone-like macrostructure in the vicinity of transducer radiating …

Cavitation refers to the formation and collapse of vapor bubbles near solid boundaries in
high-speed flows, such as ship propellers and pumps. During this process, cavitation …
