Graphene (noun, “GRA-feen”)
This is a sheet of carbon atoms that is only one atom thick. Graphene is so thin that 25,000 sheets of it stacked on each other are only as thick as a piece of paper. But graphene is incredibly strong — 200 times stronger than steel. It can also conduct electricity. Graphene can be used to make ultra-thin parts for computers, cell phones and more.
