What makes graphene the wonder material?

The answer

Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, making it the thinnest material possible at just one atom thick. Despite this, it is roughly 200 times stronger than steel by weight, conducts electricity better than copper, conducts heat better than any known material, and is nearly transparent. It was first isolated in 2004 by Andre Geim and Konstantin Novoselov using ordinary sticky tape to peel layers from graphite - an experiment so simple yet profound that it won them the 2010 Nobel Prize in Physics.
