ORNL's James Klett with his LED-cooling graphite foam

LED lamps may soon be able to go much longer between fixture replacements thanks to a new graphite foam cooling system developed at the US Department of Energy's Oak Ridge National Laboratory (ORNL). The graphite foam works by passively wicking heat away from the lamp via its lightly-packed, open skeletal structure – and given that a ten-degree decrease in operating temperature can double the lifespan of LED lighting components, the benefits of keeping them cool are clear.  Read More

The multi-metallic nanoparticle created for fuel-cell reactions uses a palladium core and ...

The most obvious obstacles for the widespread adoption of fuel cell technology are cost and performance. Although they promise benefits over internal combustion engines and batteries in terms of environmental impact, they are still fairly limited in use for these reasons. One of the most expensive elements used in most fuel cells is platinum, but now researchers have created a unique core and shell nanoparticle that uses far less platinum, yet performs more efficiently and lasts longer than commercially available pure-platinum catalysts at the cathode end of fuel cell reactions.  Read More

Carbon nanotubes could be used to create a  bionic sense of touch (Photo: Mstroeck)

The human body is an amazingly complex bit of kit. Replicating it with bionic technology presents challenges on many fronts, including the formidable task of mimicking our sense of touch. This goal could now be a little closer thanks to a breakthrough in carbon nanotube processing by scientists at Oak Ridge National Laboratory. Borrowing from conventional methods of making glass fiber, the researchers managed to cram 19,600 individual carbon nanotube-containing channels into fibers just four times thicker than a human hair, putting the artificial structure on a scale similar to the tiny neural bundles that make up our nerve pathways.  Read More

Posters of the periodic table on the walls of science labs in schools around the world will need to be updated after the discovery of the newest superheavy element, element 117. With the temporary name of ununseptium, the temporary symbol Uus and the atomic number 117, it was the only missing element in row seven of the periodic table until its discovery by an international team of scientists from Russia and the U.S.  Read More

A team of scientists from the Universidad Complutense de Madrid (UCM) has designed a new "super-lattice" material with incredibly high ion conductivity properties that could lead to the development of more efficient fuel cells capable of operating at room temperature.  Read More
