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, ...
Systematic inclusion of defects in pure carbon single-wall nanotubes and their effect on the Raman D-band
(Elsevier: Chemical Physics Letters, 2005-01-11)
The Raman D-band feature (∼1350 cm[-][1]) is examined with 2.54 eV excitation for pure bulk carbon single-wall nanotube samples before and after treatments that increase defect densities. Upon employing mass-transport-limited ...
Electrochemical transformation of SWNT/Nafion composites
(The Electrochemical Society: Electrochemical and Solid State Letters, 2004-10-08)
The electrochemical performance of single wall carbon nanotube (SWNT)/Nafion composite electrodes were studied in sulfuric acid solutions. Electrochemical oxidation of the highly dispersed SWNTs within the Nafion matrix ...
Assessing the hydrogen adsorption capacity of single-wall carbon nanotube / metal composites
(American Institute of Physics Conference Proceedings: Hydrogen in Materials and Vacuum Systems, 2003-07-11)
Carefully controlled and calibrated experiments indicate a maximum capacity for adsorption of hydrogen on SWNTs is ~8 wt% under room temperature and pressure conditions. Samples displaying this maximum value were prepared ...
Formation of single-wall carbon nanotube superbundles
(The American Chemical Society: Chemistry of Materials, 2000-03)
Since their discovery in 1993, carbon single-wall nanotubes (SWNTs) have been of great interest because of their expected novel electronic, mechanical, and gas adsorption properties. Difficulties arise in measuring these ...
A simple and complete purification of single-walled carbon nanotube materials
