Tucker Oppenheim April 29, 2011 Gray C block Friday reading Graphene The material graphene can be described as a tiny layer composed of graphite. In the article it goes over the possibility of graphene being used as a new and up and coming material. The reason they think this is because it is the thinnest material able to be made. Some uses they believe might be useful are the use of graphene in the making of batteries. The goal would be to minimize the space required for battery operation. In addition to it's thin demeanor, they say its trait's will change future technology greatly. It is said to be 200 times stronger than steel. In addition to its strength it is also the best electricity conductor.
