A new approach to building efficient thermoelectric nanomaterials

By doping a thermoelectric material with minute amounts of sulfur, a team of researchers has found a new path to large improvements in the efficiency of materials for solid-state heating and cooling and waste energy recapture. ...

Graphene isn't the only Lego in the materials-science toy box

You may have heard of graphene, a sheet of pure carbon, one atom thick, that's all the rage in materials-science circles, and getting plenty of media hype as well. Reports have trumpeted graphene as an ultra-thin, super-strong, ...

Keeping cool with a black semiconductor

As anyone who has held a laptop computer or cell phone knows, they produce heat that has the potential to damage the microchips inside. However, layered, crystalline black phosphorus could lead to a new microchip design that ...

Bacteria hairs make excellent electrical wires

Although proteins are usually electrically insulating, hair-like nanoscale filaments (called pili) on the surface of Geobacter bacteria exhibit metallic-like conductivity. To understand why pili are conductive, scientists ...
