Ultrasonic cavitation device is a surgical device using low frequency ultrasound energy to dissect or fragment tissues with low fiber content. It is basically an ultrasound probe (acoustic vibrator) combined with an aspirator device ( suction ). [1] It is mainly used for tissues with high water content and low fiber content, like noncirrhotic ...
Ultrasonic cleaning. Ultrasonic cleaning is a process that uses ultrasound (usually from 20 to 40 kHz) to agitate a fluid, with a cleaning effect. Ultrasonic cleaners come in a variety of sizes, from small desktop units with an internal volume of less than 0.5 litres (0.13 US gal), to large industrial units with volumes approaching 1,000 litres ...
Single-bubble sonoluminescence – a single, cavitating bubble. Sonoluminescence is the emission of light from imploding bubbles in a liquid when excited by sound. Sonoluminescence was first discovered in 1934 at the University of Cologne. It occurs when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse ...
Sonic weapon. A long-range acoustic device ( LRAD) in use on the USS Blue Ridge. Sonic and ultrasonic weapons ( USW) are weapons of various types that use sound to injure or incapacitate an opponent. Some sonic weapons make a focused beam of sound or of ultrasound; others produce an area field of sound. As of 2023 military and police forces ...
Sonochemistry. In chemistry, the study of sonochemistry is concerned with understanding the effect of ultrasound in forming acoustic cavitation in liquids, resulting in the initiation or enhancement of the chemical activity in the solution. [1] Therefore, the chemical effects of ultrasound do not come from a direct interaction of the ultrasonic ...
Ultrasonic antifouling. Ultrasonic antifouling is a technology that uses high frequency sound ( ultrasound) to prevent or reduce biofouling on underwater structures, surfaces, and medium. Ultrasound is just high frequency sound (which humans can not hear). Ultrasound has the same physical properties as human-audible sound.
A directed-energy weapon ( DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel, missiles, vehicles, and optical devices. [1] [2]
Sonication. Sonication is the act of applying sound energy to agitate particles in a sample, for various purposes such as the extraction of multiple compounds from plants, microalgae and seaweeds. [1] Ultrasonic frequencies (> 20 kHz) are usually used, leading to the process also being known as ultrasonication or ultra-sonication.
