Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...

Kelvin wakes: patterns seen in cleaved silicon resemble the wakes made by these boats. (Courtesy: Arpingstone) Unwanted roughness on cleaved silicon surfaces is created by an acoustic effect that is ...

Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they ...

Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors ...
