Removing dental plaque and calculus, that is the build-up of tartar or hard plaque, is a big part of maintaining oral health. Cavitation or bubble formation occurs around dental ultrasonic scalers, ...

Bubbles can be microbe killers. Scientists have long known that ultrasound in liquids causes gas bubbles to form and then often collapse violently. When those bubbles implode in cleaning solutions, ...

A new method to improve the aggressive intensity of cavitation without the need to increase the input power is under development, report scientists. Cavitation -- the formation, growth and subsequent ...

Ultrasonic therapy often uses targeted ultrasound waves to create cavitation bubbles -- tiny balloons of rapidly oscillating air pockets that stretch nearby cell membranes when they burst. This ...

DURHAM, N.C. -- Researchers at Duke University have discovered a way to enhance the effectiveness and safety of sonogenetics or ultrasonic modulation, emerging techniques that use sound waves to ...
