Understanding how sound waves travel through disordered materials

A team of researchers lead by the University of Tsukuba have created a new theoretical model to understand the spread of vibrations through disordered materials, such as glass. They found that as the degree of disorder increased, ...

Sound waves spin droplets to concentrate, separate nanoparticles

Mechanical engineers at Duke University have devised a method for spinning individual droplets of liquid to concentrate and separate nanoparticles for biomedical purposes. The technique is much more efficient than traditional ...

Physicists capture the sound of a 'perfect' fluid

For some, the sound of a "perfect flow" might be the gentle lapping of a forest brook or perhaps the tinkling of water poured from a pitcher. For physicists, a perfect flow is more specific, referring to a fluid that flows ...
