So lately (meaning the past few years) I've been hearing a lot about graphene and how it's amazing. It's apparently super strong, has a high conductivity and many other amazing properties. It was the subject for which a nobel prize was won, and it supposedly will change the future. I can't profess to have a great deal of knowledge in any field of science, just a burning curiosity. So my question is this: is graphene all that, or is just another one of those pieces of science that has been over sensationalized and wont come to anything much?
