摘要：

Novel carbon nanofibers (see Figure) are synthesized by capillary impregnation of discotic mesophase pitch into nanochannel alumina. Heating and chemical etching produces nanofibers with a unique "orthogonal" arrangement of graphene layers. Unlike conventional nanofibers and -tubes, the graphene planes lie transverse to the fiber axis, which reflects the equilibrium state for the discotic precursor confined to nanocylindrical geometry.
