As you are reading this, you probably have a pencil in your hand. In the center of every pencil is something called "lead." This dark gray material is not actually lead (Pb), but a different substance, graphite. Graphite has been a major area of research for many years. It is made up of thin layers of carbon that can be easily separated. Indeed, it is this ease of separation that enables the pencil to write. As the pencil rubs against the paper, thin layers of carbon are pulled off the pencil lead and left on the paper as lines or writing. In 2004, two scientists, Andre Geim and Konstantin Novoselov, were investigating graphite at the University of Manchester, in the UK. They were trying to see if they could obtain a very thin slice of graphite to study. Their goal was to get a slice of carbon which was between 10 and 100 layers thick. Even though their university laboratory had the latest scientific equipment, they made their incredible breakthrough — for what was later to become a Nobel Prize-winning discovery — with only a cheap roll of sticky tape. つづく
