Infrared amplifier reaches the nanoscale
Jul 22, 2015
Researchers in China and the US have unveiled the first nanoscale amplifier for light at the technologically important telecommunications wavelength of 1.55 µm (or the near-infrared). The new device, which is 20 times more powerful than previous such amplifiers that measured microns across, is small enough to fit on an integrated circuit. This means that it could help make for the next generation of faster, more efficient, nanophotonics components. [via nanotechweb and APS]
From graphene hydrogels to high-performance anodes
Mar 18, 2015
How can the electrodes of batteries be made more efficient? In the journal Angewandte Chemie, American scientists describe a powerful approach that uses solvated graphene frameworks as the anode material. Assembled in a lithium coin cell, the as-made electrode excelled with capacities surpassing the values of typically used graphite. [via nanowerk.com]
