... and 98.4 percent purity was produced on the heated anode surface in hydrogen DC arc-discharge [1]. Hydrogen arc plasma was generated between the graphite cathode and the carbon/metal composite anode (Fe/Co/Ni/FeS). X-ray diffraction analysis revealed that the carbon nano-fiber had a turbostratic ...

... a bit of soot. Such strands were exceptionally long, thin tubes of pure carbon, measuring only 10 nanometers across with the patterned symmetry of graphite. The nanotubes reportedly have superior physical properties; they are highly efficient conductors of electricity and heat, and have great tensile ...
