Hollow graphene aerogel fibers mimicking polar bear hair achieve record-low thermal conductivity and high electrical ...

Graphene is often described as a wonder material. It is strong, electrically conductive, thermally efficient, and remarkably versatile. Yet despite more than a decade of excitement, many ...

The natural world possesses its own intrinsic electrical grid composed of a global web of tiny bacteria-generated nanowires in the soil and oceans that “breathe” by exhaling excess electrons. In a new ...

A newly developed, highly conductive copper wire could find applications in the electric grid, as well as in homes and businesses. The finding defies what's been thought about how metals conduct ...

Bacteria can carry electrical currents and can use electricity for power. An international team of scientists has now found that bacteria can act like power lines, and send electrical currents over ...

Defying conventional scientific knowledge about electrical conductivity, the addition of a common carbon compound to copper to make electrical wires results in significant performance enhancements, ...

Researchers at the University of Chicago have created new materials that make OLED displays fully stretchable. Their key advance is an aluminium electrode embedded in a gallium–indium alloy, allowing ...
