New technique for stopping electrons could enable graphene-based switching mechanisms, paving the way for its use in computing and other applications Wonder-material graphene is a promising candidate for electronic devices, thanks to its excellent conductivity. However, there is a catch: electrons move through the material so well that they can’t …

New paper suggests that coupling graphene with another material could enable it to superconduct, opening up applications in computing and energy storage Since its discovery in 2004, scientists have believed that graphene may have the innate ability to superconduct. Now Cambridge researchers have found a way to activate that previously …

The mysterious case of the disappearing electric nosewheels

dreamstime_s_30604816

Fitting electric nosewheels to aircraft could reduce weight and improve efficiency – so where are they? Aircraft ground manoeuvring wastes energy. With gas turbines running inefficiently at minimum power while taxiing, or while just waiting for a slot, a typical A320/737 will consume 600 kgs of kerosene every day of …

New Fuel Cell Design Powered by Graphene-wrapped Nanocrystals (Berkeley Lab)

graphene-sheets-magnesium-nanocrystal large background

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new materials recipe for a battery-like hydrogen fuel cell—which surrounds hydrogen-absorbing magnesium nanocrystals with atomically thin graphene sheets—to push its performance forward in key areas. The graphene shields the nanocrystals from oxygen and moisture …
