Graphene Graphene Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is a semimetal with small overlap between the valence and the conduction bands (zero bandgap material).<ref name="10.1002/adma.201502544 p.6519-6525"></ref> It is the basic structural element of many other allotropes of carbon, such as graphite, diamond, charcoal, carbon nanotubes and fullerenes. Graphene has many uncommon properties. It is the strongest material ever tested, conducts heat and electricity efficiently, and is nearly transparent. Graphene shows a large and nonlinear diamagnetism, greater than that of graphite, and can be levitated by neodymium
Carbon Glacier Carbon Glacier Carbon Glacier is located on the north slope of Mount Rainier in the U.S. state of Washington and is the source of the Carbon River. The snout at the glacier terminal moraine is at about above sea level, making it the lowest-elevation glacier in the contiguous United States. The glacier also has the greatest length (), thickness () and volume () of any U.S. glacier outside of Alaska. Carbon Glacier is accessible from the northwest Carbon River entrance of Mount Rainier National Park, just outside the town of Carbonado, Washington. The glacier is accessible on foot via an
