Melt-grown curved graphite crystals

precipitated from molten iron, nearly ideal graphite

This work explores a
gap in the field of carbon
materials. Metal catalysts have facilitated the synthesis of a wide
range of graphitic materials for decades. At one end of the range is nearly ideal kish graphite, which is
composed of large, flat, highly oriented graphene layers. Fullerenes,
on the other hand, contain graphene of nanometer-scale curvature[2,3].
Between the extremes of conventional graphite and fullerenes, we may anticipate
an immense variety of carbons in which the graphene molecules have an
intermediate degree of curvature. The following galleries present an
assortment of the intermediate-curvature graphites precipitated from iron,
nickel and cobalt, so far.
