Revolutionizing Technology With Graphene
By Veronica Villanueva, C2ST Intern, Rush University
People will often call the end of a pencil the “lead tip,” but there is no lead in pencils. Pencils are filled with graphite, a crystalline form of carbon. Carbon is a fascinating element. It is found in many commonplace items like paper, food, and medicine. Even we are made of carbon. Carbon is essential. It creates extremely strong bonds and is tetravalent (it has 4 spare electrons to bind other elements) making carbon a perfect building block for our world.
