CARBON exhibits a unique ability to form a wide range of structures. In an inert atmosphere it condenses to form hollow, spheroidal fullerenes1–4. Carbon deposited on the hot tip of the cathode of the arc-discharge apparatus used for bulk fullerene synthesis will form nested graphitic tubes and polyhedral particles5–8. Electron irradiation of these nanotubes and polyhedra transforms them into nearly spherical carbon 'onions'9. We now report that covaporizing carbon and cobalt in an arc… 
Crystalline Ropes of Metallic Carbon Nanotubes
TLDR
X-ray diffraction and electron microscopy showed that fullerene single-wall nanotubes (SWNTs) are nearly uniform in diameter and that they self-organize into “ropes,” which consist of 100 to 500 SWNTs in a two-dimensional triangular lattice with a lattice constant of 17 angstroms.
Single-Wall Carbon Nanotubes and Single-Wall Carbon Nanohorns
Metal catalysts take forms of nanometer-sized particles in the condensed carbon phase and catalyze the growth of single-wall carbon nanotubes at about 1200 °C. The good metal catalysts in forming
A structure model and growth mechanism for novel carbon nanotubes
The growth of carbon nanotubes from catalytic thermal decomposition of acetylene on fine iron particles has been studied. Electron microscopic images of the carbon nanotubes “as formed” and after
Growth of Large-Diameter Single-Walled Carbon Nanotubes
Single-walled carbon nanotubes (SWNTs) give every indication that they will make a major impact on science and technology. Their unusual physical and chemical properties, which depend on nanotube

Graphite whiskers have been grown in a dc arc under a pressure of 92 atmospheres of argon and at 3900°K. They are embedded in a solid matrix of graphite which builds up by diffusion of carbon vapor

Curling and closure of graphitic networks under electron-beam irradiation
TLDR
The response of carbon soot particles and tubular graphitic structures to intense electron-beam irradiation in a high-resolution electron microscope is reported, suggesting that planar graphite may not be the most stable allotrope of carbon in systems of limited size.
Catalytic growth of carbon microtubules with fullerene structure
A method to grow carbon microtubules with fullerene structure (buckytubes) has been identified. The method consists of the catalytic decomposition of acetylene over iron particles at 700 °C. Carbon
Electronic structure of graphene tubules based on C60.
TLDR
A simple tight-binding model shows that some fibers are metallic and are stable against perturbations of the one-dimensional energy bands and the mixing of σ and π bands due to the curvature of the circumference of the fiber.
