Graphene is a sheet just one atom thick, prized for being far stronger than steel yet flexible and a superb conductor of electricity.
Graphene is made of a single layer of carbon atoms arranged in a repeating honeycomb pattern, and that specific arrangement is what gives it such extraordinary properties. Carbon atoms in this hexagonal lattice bond so strongly and efficiently that the resulting sheet, despite being only one atom thick, is exceptionally strong, flexible, and an excellent conductor of both electricity and heat.
Silicon is the element behind computer chips and solar cells but does not form the same ultra-thin honeycomb sheet material known as graphene. Titanium is a strong, lightweight metal used in aerospace and medical implants, chemically and structurally unrelated to this carbon-based material.
The scientists who first isolated graphene in the lab did so using little more than sticky tape to peel layers off a block of graphite, work simple enough to be replicated by students yet significant enough to win a Nobel Prize.
