Lab-made hexagonal diamonds stiffer than natural diamonds

Nature's strongest material now has some stiff competition. For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than the common cubic diamonds found in nature and often used in ...

Optimal design for acoustic unobservability in water

Until now, it was only possible to optimize an acoustic cloaking structure for the air environment. However, with this latest research, "Acoustic cloak designed by topology optimization for acoustic-elastic coupled systems," ...

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 ...
