Electron microscopy at the Department of Energy's Oak Ridge
National Laboratory is providing unprecedented views of the individual atoms in
graphene, offering scientists a chance to unlock the material's full potential
for uses from engine combustion to consumer electronics.
Graphene crystals were first isolated in 2004. They are
two-dimensional (one-atom in thickness), harder than diamonds and far stronger
than steel, providing unprecedented stiffness, electrical and thermal
properties. By viewing the atomic and bonding configurations of individual
graphene atoms, scientists are able to suggest ways to optimize materials so
they are better suited for specific applications.
