Arsenic helps make black phosphorus stable for energy efficiency

The quest for thermoelectric materials that efficiently convert changes in temperature into electric voltage is challenging. For optimal performance, a material must conduct small amounts of heat and large amounts of electricity. ...

A zigzag blueprint for topological electronics

A collaborative study led by the University of Wollongong confirms switching mechanism for a new, proposed generation of ultra-low energy topological electronics.

What makes plants electrically excitable

Plant cells use electrical signals to process and transmit information. In 1987, as a postdoc of Erwin Neher in Göttingen, biophysicist Rainer Hedrich discovered an ion channel in the central vacuole of the plant cell, which ...

Remote high-voltage sensor unveiled

Ever since the first human placed a bare hand on an uninsulated electric line, people have refrained from personally testing energetic materials. Even meters made of metal can melt at high voltages.

Team develops sensitive new way of detecting transistor defects

Researchers at the National Institute of Standards and Technology (NIST) and collaborators have devised and tested a new, highly sensitive method of detecting and counting defects in transistors—a matter of urgent concern ...

Reconfigurable metasurfaces provide nanoscale light control

Researchers have designed electromechanically reconfigurable ultrathin optical elements that can be controlled and programmed on a pixel-by-pixel level. These versatile metasurfaces could offer a new chip-based way to achieve ...
