Graphene’s stabling influence

more »
Supercapacitors can be charged and discharged tens of thousands of times, but their relatively low energy density compared to conventional batteries limits their application for energy storage. Now, researchers in Singapore have developed an 'asymmetric' supercapacitor based on metal nitrides and graphene that could be a viable energy storage solution.

Rosetta and Comet Outbound

more »
Not a bright comet, 67P/Churyumov-Gerasimenko now sweeps slowly through planet Earth's predawn skies near the line-up of planets along the ecliptic. Still, this composite of telescopic images follows the comet's progress as it moves away from the Sun beyond the orbit of Mars, from late September (left) through late November (far right). Its faint but extensive coma and tails are viewed against the colorful background of stars near the eastern edge of the constellation Leo. A year ago, before its perihelion passage, the comet was less active, though. Then the Rosetta mission's lander Philae made it's historic landing, touching down on the surface of the comet's nucleus.
