We were always amused that one of the biggest scientific discoveries of the recent past — graphene — was started with pencil lead and Scotch tape. Now, researchers at the University of Alabama ...

Illustration of the Scotch tape method for isolating graphene. A piece of graphite is placed on adhesive tape, which is then folded over and peeled apart repeatedly to cleave the graphite into thinner ...

Their technique centered around "pulling" strands of graphene out of a sample of pure graphite by using the so-called Scotch ...
