Carbon nanostructures are mass produced from graphite. In particularly preferred aspects, graphene is thermo-chemically derived from graphite and used in numerous compositions. In further preferred aspects, the graphene is re-shaped to form other nanostructures, including nanofractals, optionally branched ...
Graphene is created when graphite – the mother form of all graphitic carbon, which is used to make the pigment, which allows pencils to write on paper – is reduced down to a one-atom-thick sheet. Graphene is among the strongest materials known and has an attractive array of benefits. Th...
(PhysOrg.com) -- Graphene is a perfect example of the wonders of nanotechnology, in which common substances are scaled down to an atomic level to uncover new and exciting possibilities. Graphene is created when graphite — the mother form of all graphitic carbon, which is used to make the ...
With a Y–Ni alloy composite graphite rod as anode for d.c. arc discharge, a cloth-like soot was produced, containing about 40% single wall carbon nanotubes (SWCNTs). By characterization with high resolution transmission electron microscope (HREM) and Raman spectroscopy, it is found that the...

carbonaceous aerosol mass concentration as independently determined by filter collection and weighing; (2) the absorption coefficient of carbonaceous aerosols is 17 m 2 g −1 at 4166 Å in rough agreement with previously measured values for bulk carbon and graphite samples of 1.4–15.0 m 2 g ...
Why is graphite a good conductor whereas diamond is not? (Both contain infinite lattices of covalently bound carbon atoms) Why is titanium tetrachloride reduced with sodium or magnesium and not hydrogen or carbon? Why are chemical equations balanced? Explain at the...

(1985), the same research group also found a magic number feature due to LaC60in a mass spectrum prepared by laser vaporization of a LaCl3impregnated graphite rod (Heath et al., 1985). They observed a series of Cn+and LaCn+ion species with LaC60+as a magic number ion in the mass ...
