Catalytic growth of single-wall carbon nanotubes from metal particles
TL;DR: In this article, the authors proposed a supported catalyst-substrate system to promote the growth of single-wall carbon nanotubes in a specific size range, rather than the large irregular-sized multi-walled carbon fibrils that are known to grow from supported catalysts.
Journal ArticleDOI
Chemical Vapor Deposition Based Synthesis of Carbon Nanotubes and Nanofibers Using a Template Method
TL;DR: In this article, a new approach for preparing graphitic carbon nanofiber and nanotube ensembles was developed, which entails chemical vapor deposition (CVD) based synthesis of carbon within the pores of an alumina template membrane with or without a Ni catalyst.
Journal ArticleDOI
The catalyst in the CCVD of carbon nanotubes—a review
TL;DR: In this paper, the role played by the catalytic chemical vapor deposition (CCVD) of CNTs is discussed, in particular the influence of the composition of the catalyst material, morphology of the nanoparticles, support, preparation method, and reduction pretreatment.

Journal ArticleDOI
Helical microtubules of graphitic carbon
TL;DR: Iijima et al. as mentioned in this paper reported the preparation of a new type of finite carbon structure consisting of needle-like tubes, which were produced using an arc-discharge evaporation method similar to that used for fullerene synthesis.
Journal ArticleDOI
Single-shell carbon nanotubes of 1-nm diameter
Sumio Iijima,Toshinari Ichihashi +1 more
TL;DR: In this article, the authors reported the synthesis of abundant single-shell tubes with diameters of about one nanometre, whereas the multi-shell nanotubes are formed on the carbon cathode.
Journal ArticleDOI
New one-dimensional conductors: Graphitic microtubules.
TL;DR: It is predicted that carbon microtubules exhibit striking variations in electronic transport, from metallic to semiconducting with narrow and moderate band gaps, depending on the diameter of the tubule and on the degree of helical arrangement of the carbon hexagons.
Journal ArticleDOI
Large-scale synthesis of carbon nanotubes
TL;DR: In this article, the authors used a variant of the standard arc-discharge technique for fullerene synthesis under a helium atmosphere, where a carbonaceous deposit formed on one of the graphite rods, consisting of a macroscopic (diameter of about 5 mm) cylinder.

Are fullerene tubules metallic
TL;DR: It is estimated that the mean-field transition temperature from a Peierls-distorted regime to a high-temperature metallic regime should be well below room temperature.
