Synthesis and characterization of boron-doped single-wall carbon nanotubes produced by the laser vaporization technique
(The American Chemical Society: Chemistry of Materials, 2006-05-16)
We present the first successful high-yield laser vaporization synthesis of high-quality boron-doped single-wall carbon nanotubes (B-SWNTs). Boron was loaded into graphite targets in the form of elemental B as well as nickel ...
Photo-oxidation of multiwalled carbon nanotubes
(Materials Research Society Proceedings: Degradation Processes in Nanostructured Materials, 2006)
MWNTs were photo-oxidized in quartz boats using low-pressure Hg lamps and emission downstream from Ar microwave plasmas which are primarily atomic line sources of 253.7 and 184.9 nm UV, and 106.7 and 104.8 nm vacuum UV ...
Photo-oxidation of singlewalled carbon nanotubes
(Materials Research Society Proceedings: Degradation Processes in Nanostructured Materials, 2006)
UV- and vacuum UV-assisted photo-oxidation of single-walled carbon nanotube (SWNT) paper occurred with: (1) atmospheric oxygen pressure using low-pressure Hg lamps (ë = 253.7 and 184.9 nm), (2) low oxygen pressure employing ...
Investigation of the electronic structure of carbon single wall nanotube hybrid nanostructures
(Plasmonic Nano-imaging and Nanofabrication: Proceedings of the SPIE, 2005-08-03)
The effects of protonation on the structure of the carbon single-walled nanotube (SWNT) polymer composites were studied by solid-state nuclear magnetic resonance (NMR) techniques and Raman spectroscopy. In addition, ...
Growth of multi-walled carbon nanotubes by injection CVD using cyclopentadienyliron dicarbonyl dimer and cyclooctatetraene iron tricarbonyl
