1. It’s touted as a miracle material, promising everything from space travel to better hair, but there isn’t much to graphene — literally. It’s a single layer of carbon atoms arranged in a repeating honeycomb-shaped pattern.

2. Graphene has great flexibility and strength, and because it’s essentially two-dimensional, electricity flows across it so quickly that it’s one of the most conductive materials known.

3. You’d be forgiven for not knowing much about it, however. Graphene had long been theorized, but it was only in 2004 that physicists Kostya Novoselov and Andre Geim proved graphene could exist on its own without being chemically bonded to other elements.

4. Just six years later, Novoselov and Geim won the Nobel Prize in Physics for their work. Also in that short span, researchers around the world published more than 5,000 papers on the material.

5. No doubt you’ve written a paper or two with ...
