ultrasonic waves

Using ultrasonic waves to propel drug molecules into the skin, the patch could be used to treat a variety of conditions

This new method of contactless manipulation could prove useful in manufacturing and robotics

Ultrasonic cleaners are suited to an extensive range of applications other than cleaning

To lyse cells, purify proteins, or develop nanotechnology, scientists and technologists often turn to ultrasonic liquid processors.

New technique to selectively and noninvasively turn on groups of neurons in worms could be boon to science and medicine
