Using a newly-developed waveguide, scientists at Yale have created a method to significantly increase the power of laser light on a silicon chip by boosting it with sound waves. The researchers ...

IT has been well established by several investigators1,2 that, in the case of diffraction of light by ultrasonic waves, the first orders of diffraction on either side of the central zero order ...

R. W. WOOD and one of us (Loomis) have described (Phil. Mag., 4, 417; September 1927) certain physical and biological effects observed with high frequency sound waves of great intensity. To obtain ...

Researchers at the University of Washington have developed a way to use sound to create cellular scaffolding for tissue engineering, a unique approach that could help overcome one of regenerative ...

Specialized photographic methods known as acousto-optic imaging can capture the differences in light intensity to study detailed characteristics of sound vibration patterns.

Brain waves: Scientists are using low-intensity, low-frequency ultrasound to activate the brain. Activated neurons in a slice of brain tissue are shown here in red.

Thermoacoustic compressors essentially compress or expand gases with high-intensity sound waves. Compressing gases generates heat, while letting the gases expand cools things off. Think of the ...
