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. ...

Decoupled graphene thanks to potassium bromide

The use of potassium bromide in the production of graphene on a copper surface can lead to better results. When potassium bromide molecules arrange themselves between graphene and copper, it results in electronic decoupling. ...

S-t-r-e-t-c-h-i-n-g electrical conductance to the limit

Individual molecules have been used to create electrical components like resistors, transistors and diodes, that mimic the properties of familiar semiconductors. But according to Nongjian (NJ) Tao, a researcher at the Biodesign ...

How do green algae react to carbon nanotubes?

Nanoparticles such as carbon nanotubes (CNT), which are found in an ever-increasing number of products, are ending up more and more frequently in our surroundings. If and how they affect aquatic ecosystems are questions which ...

Thermoelectric power generation at room temperature: Coming soon?

Thermoelectric (TE) materials could play a key role in future technologies. Although the applications of these remarkable compounds have long been explored, they are mostly limited to high-temperature devices. Recently, researchers ...
