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 ...
Protonation of carbon single-walled nanotubes studied using 13C and 1H-13C cross polarization nuclear magnetic resonance and raman spectroscopies
(The American Chemical Society: Journal of the American Chemical Society, 2005-12-14)
The reversible protonation of carbon single-walled nanotubes (SWNTs) in sulfuric acid and Nafion was investigated using solid-state nuclear magnetic resonance (NMR) and Raman spectroscopies. Magic-angle spinning (MAS) was ...
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, ...
Development and characterization of single wall carbon nanotube–Nafion composite actuators
