A promising method for producing conductive graphene sheets

Since the isolation of graphene by the “Scotch tape” method, many researchers have tried to synthesize solution-dispersible graphene. The challenge has been to develop a high-yield method that can exfoliate graphite efficiently into solution-dispersible graphene sheets without collateral damage to…

Solvent extraction method shows promise for recovering bitumen from tar sands

Today only a few percent of Canada’s oil sands resource is accessible by traditional surface mining, so the rest has to be recovered in situ, mostly by steam-assisted gravity drainage (SAGD). In this process, steam is injected into a horizontal…
