Shaking light with sound

Piezoelectric materials can convert electrical voltage to mechanical displacement and vice versa. They are ubiquitous in modern wireless communication networks such as in cellphones. Today, piezoelectric devices, including ...

Seeing with radio waves

Scientists from the Division of Physics at the University of Tsukuba used the quantum effect called 'spin-locking' to significantly enhance the resolution when performing radio-frequency imaging of nitrogen-vacancy defects ...

'Virtual pillars' separate and sort blood-based nanoparticles

Engineers at Duke University have developed a device that uses sound waves to separate and sort the tiniest particles found in blood in a matter of minutes. The technology is based on a concept called "virtual pillars" and ...
