Have you heard about graphene? This is one of the new wonder materials that has had scientists and researchers abuzz since 2003.
Graphene is a version of graphite - yes, the stuff in pencil lead. However, graphene is only a single atom thick and comes in sheets. In that form, it has more uses that I have space to mention, but I'll give you some highlights.
Graphene conducts electricity like a superconductor and it's incredibly strong for its weight. It could replace silicon in computer chips because it will run up to one hundred times faster, but use less electricity and take up less space.
Because it's only a single atom thick, graphene is transparent, making it perfect for electronic components in touch screens and electronic displays. It will even bend, so foldable smartphones could be the future.
