  author={Sumio Iijima and Toshinari Ichihashi},
CARBON nanotubes1 are expected to have a wide variety of interesting properties. Capillarity in open tubes has already been demonstrated2–5, while predictions regarding their electronic structure6–8 and mechanical strength9 remain to be tested. To examine the properties of these structures, one needs tubes with well defined morphologies, length, thickness and a number of concentric shells; but the normal carbon-arc synthesis10,11 yields a range of tube types. In particular, most calculations… 
Carbon Nanotubes: Properties and Applications
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
The Functionalization of Carbon Nanotubes and Nano‐Onions
The unique structure and morphology of carbon nanotubes have kept attracting researchers to explore their novel properties and applications since their discovery by Iijima in 1991 (1). Carbon
Nanometre-size tubes of carbon
We review the present state of understanding of the structure, growth and properties of nanometre-size tubes of carbon. Two different types of carbon nanotubes, namely single-shell nanotubes made of
Growth of single-wall carbon nanotubes within an ordered array of nanosize silica spheres
Single-wall carbon nanotubes (SWCNTs), which were well-separated individuals or, small bundles of two to five tubes, were produced in a controllable manner by disproportionation of CO at 700 °C and 1
A step toward production of smaller diameter single wall carbon nanotubes
Single-wall carbon nanotubes were produced with, either, a bimetallic or a mixture of three catalysts. Raman scattering and high resolution transmission electron microscopy were used as
SUMMARY Carbon nano-tubes (CNTs) are hollow cylinders of graphite carbon atoms. These tubes are on the nanoscale (10 -9 m), which is so small that 10,000 of them could fit within the diameter of one


Large-scale synthesis of carbon nanotubes
INTEREST in carbon fibres1,2 has been stimulated greatly by the recent discovery of hollow graphitic tubules of nanometre dimensions3. There has been much speculation about the properties and
Thinning and opening of carbon nanotubes by oxidation using carbon dioxide
THE discovery1 and bulk synthesis2 of carbon nanotubes has stimulated great interest. It has been suggested that these structures may have useful electronic3–5 and mechanical6 properties, and these
Helical microtubules of graphitic carbon
THE synthesis of molecular carbon structures in the form of C60 and other fullerenes1 has stimulated intense interest in the structures accessible to graphitic carbon sheets. Here I report the
Opening carbon nanotubes with oxygen and implications for filling
CAPPED hollow carbon nanotubes1,2 can be modified into nanocomposite fibres by simultaneous opening of the caps (by heating in the presence of air and lead metal) and filling of the interior with an
Capillarity-induced filling of carbon nanotubes
THE recent discovery1 and bulk synthesis2 of nanometre-scale carbon tubules has led to much speculation about possible uses of these graphitic structures3–5. Broughton and Pederson predicted on the
Growth model for carbon nanotubes.
A novel structure that shows complete ``turn around growth,'' involving pentagon-heptagon pairs, of the tubular assemblies is presented.
Electronic structure of graphene tubules based on C60.
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.
Pentagons, heptagons and negative curvature in graphite microtubule growth
THE standard carbon-arc synthesis for fullerenes also produces graphitic microtubules with helical structures1. In most cases the cylindrical tubes are closed by polyhedral caps, some being first
Preparation of Carbon Nanotubes by Arc-Discharge Evaporation
Extremely thin graphite filaments with a tubular structure were grown in carbon deposits formed on the negative electrode during generation of fullerenes by dc carbon-arc-discharge evaporation. The
