Hexagonal graphene “onion rings” grown at Rice University.

Onion rings to feed Li-ion?

Researchers at Rice University have discovered a potentially new graphene variant that could be applied to lithium-ion (Li-ion) batteries. Concentric hexagons of graphene grown in a furnace at the university represent the first time anyone has synthesised…

Nanotechnologists produce micro-supercapacitor

Researchers at Rice University in the US have made a new hybrid micro-supercapacitor from graphene and carbon nanotube ‘carpets’, reports nantechweb.org. These structures have electrochemical properties that could be just the thing for running portable…
