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 ...
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 ...
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 ...
Laser synthesis of single-wall carbon nanotubes utilizing high temperature induction heating.
(Materials Research Society Proceedings: Nanotubes and Related Materials, 2001)
An inductive heating system was used to control the temperature of the target during laser synthesis of SWNTs. The position of the target relative to the heating coil, the type of catalyst metals and the synthesis temperatures ...
Rapid, room temperature, high-density hydrogen adsorption on single-walled carbon nanotubes at atmospheric pressure assisted by a metal alloy
(Materials Research Society 2000 Fall Meeting: Symposium A: Nanotubes and Related Materials, 2001)
Laser-generated, carbon single-walled nanotubes (SWNTs) adsorb hydrogen in a matter of minutes at room temperature and atmospheric pressure in the presence of a Ti-6Al-4V metal alloy. The unusual hydrogen adsorption ...
Evaluating the purity of single-wall nanotube materials
(Materials Research Society: 2000 Fall Proceedings Symposium A: Nanotubes and Related Materials, 2001)
Carbon single-wall nanotubes (SWNTs) have a variety of unique physical, electronic and mechanical properties. However, the SWNTs must be thoroughly purified if they are to be used in the wide array of projected applications ...
Adsorption of hydrogen on carbon single-walled nanotubes as measured by the volumetric technique
(Materials Research Society Proceedings: Symposium A: Nanotubes and Related Materials, 2000)
We report on hydrogen adsorption onto carbon single-walled nanotube (SWNT) material as measured by the volumetric technique. This method determines the amount adsorbed by monitoring the pressure in a known volume at a known ...
A simple and complete purification of single-walled carbon nanotube materials
