Nanotoroidal carbon

  • Pentagonal and heptagonal defects induce nanotube chirality
  • Colossal Paramagnetic Moments in Metallic Carbon Nanotori ... are due to the interplay between the toroidal geometry and the ballistic motion of the π electrons in the metallic nanotube for certain values of the magic radii .
