Effect of the Growth Temperature on the Diameter Distribution and Chirality of Single-Wall Carbon Nanotubes
Pulsed laser vaporization of a heated, Fe/Ni or Co/Ni catalyzed, carbon target in argon gas has been used to synthesize single-wall carbon nanotubes (SWNTs). Electron microscopy, x-ray diffraction,Expand

Raman scattering study of double-wall carbon nanotubes derived from the chains of fullerenes in single-wall carbon nanotubes
Abstract Double-wall carbon nanotubes (DWNTs) were prepared in quantitative amount from the chains of C60 molecules generated inside single-wall carbon nanotubes (SWNTs). The C60 molecules inside theExpand

Nano-aggregates of single-walled graphitic carbon nano-horns
Abstract We have found a new type of carbon particle produced by the CO 2 laser ablation of carbon at room temperature without a metal catalyst. The product has a powder form of graphitic particlesExpand

Evidence for charge transfer in doped carbon nanotube bundles from Raman scattering
Single-walled carbon nanotubes (SWNTs) are predicted to be metallic for certain diameters and pitches of the twisted graphene ribbons that make up their walls. Chemical doping is expected toExpand

Preparation, photocatalytic activities, and dye-sensitized solar-cell performance of submicron-scale TiO2 hollow spheres.
We prepared submicron-scale spherical hollow particles of anatase TiO2 by using a polystyrene-bead template. The obtained particles were very uniform in size, with a diameter of 490 nm and a shellExpand

Electron diffraction study of one-dimensional crystals of fullerenes
A variety of fullerene molecules are found to be fully packed in the interior space of a single-wall carbon nanotube (SWNT) and form a novel one-dimensional crystal with a regular intermolecularExpand

Raman scattering study on fullerene derived intermediates formed within single-wall carbon nanotube: from peapod to double-wall carbon nanotube
Abstract By heating of C60 peapods at 900 °C in vacuum, eight or more Raman peaks associated with the inner tubes were observed in the frequency range of the radial breathing mode vibration. AnExpand
