    • Development and characterization of single wall carbon nanotube–Nafion composite actuators 

      Landi, Brian; Raffaelle, Ryne; Heben, Michael; Alleman, Jeffrey; VanDerveer, William; Gennett, Thomas (Elsevier: Materials Science and Engineering B, 2005-02-15)
      The development and characterization of thin film polymeric actuators has been performed for single wall carbon nanotube (SWNT)–Nafion composite systems. Previous work in our laboratory illustrated that incorporation of ...

    • Effects of adsorbed O2, H2, CO2 and H2O on the optical properites of pure and polymer encapsulated single walled carbon nanotubes 

      Gennett, Thomas; Roe, Jo; VanDerveer, William; Fever, Adam; Landi, Brian; Raffaelle, Ryne; Alleman, Jeffrey; Dillon, Anne; Heben, Michael (American Physical Society: Annual APS March Meeting, 2002-03-18)
      We have measured the optical absorption spectra of single wall carbon nanotubes (SWCNTs) and SWCNT-polymer matrix samples at several temperatures and pressures. An in-situ cell was designed that allowed for heating of ...

    • Effects of alkyl amide solvents on the dispersion of single-wall carbon nanotubes 

      Landi, Brian; Ruf, Herbert; Worman, James; Raffaelle, Ryne (The American Chemical Society: Journal of Physical Chemistry B, 2004-11-04)
      Stable dispersions of both as-produced (raw soot) and purified laser-generated single-wall carbon nanotubes (SWNTs) have been demonstrated with several alkyl amide solvents. Optical absorption analysis over a range of ...

    • Electrochemical transformation of SWNT/Nafion composites 

      Liu, Ping; Lee, Se-Hee; Yan, Yanfa; Gennett, Thomas; Landi, Brian; Dillon, Anne; Heben, Michael (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 ...

    • Fuel cell applications of nanotube-metal supported catalysts 

      Gennett, Thomas; Landi, Brian; Elich, J.; Jones, K.; Alleman, Jeffrey; Lamarre, P.; Morris, R.; Raffaelle, Ryne; Heben, Michael (Materials Research Society Proceedings Fall 2002: Materials for Fuel Cells and Fuel Processors, 2002-12-02)
      Novel carbon materials with nanometer dimensions are of potentially significant importance for a number of advanced technological applications. Within this report we describe the results for the electrochemical characterization ...

    • Growth and characterization of multi-walled carbon nanotubes at NASA Glenn Research Center 

      Harris, Jerry; Hepp, Aloysius; Raffaelle, Ryne; Gennett, Thomas; Vander Wal, Randy; Landi, Brian; Luo, Yu; Scherson, Daniel (American Institute of Aeronautics and Astronautics, 2003-08-17)
      Aligned multi-walled carbon nanotubes were prepared by the injection chemical vapor deposition (CVD) method using an iron-based organometallic compound as the catalyst source and toluene as the solvent. The concentration ...

    • Growth of multi-walled carbon nanotubes by injection CVD using cyclopentadienyliron dicarbonyl dimer and cyclooctatetraene iron tricarbonyl 

      Harris, Jerry; Raffaelle, Ryne; Gennett, Thomas; Landi, Brian; Hepp, Aloysius (Elsevier: Materials Science and Engineering B, 2005-02-15)
      Preferential oriented multiwalled carbon nanotubes were prepared by the injection chemical vapor deposition (CVD) method using either cyclopentadienyliron dicarbonyl dimer or cycloctatetraene iron tricarbonyl as the iron ...
