Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations. While ...
A team of Caltech researchers is proposing a radical new technique for killing cancer cells using low-intensity ultrasound waves. The preliminary research is still at an incredibly early stage but ...
Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the ...
Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Water, ...
A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...
