(Phys.org)—Over the past few years, Li-air batteries (more precisely, Li-oxygen batteries) have become attractive due to their theoretical ability to store nearly as much energy per volume as gasoline. The key to this high ...
A new route to making graphene has been discovered that could make the 21st century's wonder material easier to ramp up to industrial scale. Graphene—a tightly bound single layer of carbon atoms with super strength and ...
