    • Adsorption of hydrogen on carbon single-walled nanotubes as measured by the volumetric technique 

      Parilla, Philip; Dillon, Anne; Gennett, Thomas; Alleman, Jeffrey; Jones, Kim; Heben, Michael (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 ...
    • Assessing the hydrogen adsorption capacity of single-wall carbon nanotube / metal composites 

      Heben, Michael; Dillon, Anne; Gilbert, Katherine; Parilla, Philip; Gennett, Thomas; Alleman, Jeffrey; Hornyak, Louis; Jones, Kim (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 ...
    • Carbon nanotube anodes for lithium ion batteries 

      Raffaelle, Ryne; Gennett, Thomas; Maranchi, Jeff; Kumta, Prashant; Hepp, Aloysius; Heben, Michael; Dillon, Anne; Jones, Kim (Materials Research Society Proceedings Fall 2001: Making Functional Materials with Nanotubes, 2002)
      Highly purified single-wall carbon nanotubes (SWCNT) were investigated for use as an anode material for thin film lithium ion batteries. The high purity nanotubes were obtained through chemical refinement of soot generated ...
    • Investigation of the electronic structure of carbon single wall nanotube hybrid nanostructures 

      Engtrakul, Chaiwat; Davis, Mark; Gennett, Thomas; Dillon, Anne; Jones, Kim; Heben, Michael (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, ...
    • Protonation of carbon single-walled nanotubes studied using 13C and 1H-13C cross polarization nuclear magnetic resonance and raman spectroscopies 

      Engtrakul, Chaiwat; Davis, Mark; Gennett, Thomas; Dillon, Anne; Jones, Kim; Heben, Michael (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 ...
    • Synthesis and characterization of boron-doped single-wall carbon nanotubes produced by the laser vaporization technique 

      Blackburn, Jeff; Yan, Yanfa; Engtrakul, Chaiwat; Parilla, Philip; Jones, Kim; Gennett, Thomas; Dillon, Anne; Heben, Michael (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 ...
