DESCRIPTION:Peel apart the layers of graphite and carefully observe the\nre
 sulting flakes\; you will find graphene\, a single atomic sheet of\ncarbon
  atoms arranged in a honeycomb lattice. The newest member of\nthe graphiti
 c family to join the fullerenes and carbon nanotubes\,\nmany of graphene's
  unique physical properties can be attributed to\nelectrons behaving like 
 massless particles. I will show how the\noptical properties of graphene ar
 e described by a fundamental\nconstant of nature\, the fine-structure cons
 tant\, and how this\nallows us to count atomic layers using only a simple 
 optical\nmicroscope. I will also describe the electronic properties of\ngr
 aphene\, including its ability to function as a transistor and the\nsensit
 ivity of its electrical conductance to the environment.\nFuture research d
 irections and potential applications of graphene\nwill be briefly discusse
 d.\n
