Scientists find a new way to make novel materials by 'un-squeezing'

Some materials can morph into multiple crystal structures with very different properties. For instance, squeezing a soft form of carbon produces diamond, a harder and more brilliant form of carbon. The Kurt Vonnegut novel ...

Designing a new material for improved ultrasound

Development of a theoretical basis for ultrahigh piezoelectricity in ferroelectric materials led to a new material with twice the piezo response of any existing commercial ferroelectric ceramics, according to an international ...

Electric textile lights a lamp when stretched

Researchers at Chalmers University of Technology have developed a fabric that converts kinetic energy into electric power. The greater the load applied to the textile and the wetter it becomes, the more electricity it generates. ...

Integrated design strategy lowers the mass and costs of motors that move objects nanometers at a time

Probing intricate cells or high-tech microchip components requires 'nanopositioners' that can scan large areas with extremely small steps. Normally, these positioners have separate fine- and coarse-movement stages, but A*STAR ...
