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 ...
Fuel cell applications of nanotube-metal supported catalysts
(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 ...
Single wall carbon nanotube-Nafion composite actuators
(The American Chemical Society: Nano Letters, 2002-11)
Single wall carbon nanotube (SWNT)-Nafion composite actuators have been demonstrated for 0.1-18% w/w doping of purified SWNTs within the polymer matrix. The high purity SWNTs, >95% w/w, were homogeneously dispersed into ...
Effects of adsorbed O2, H2, CO2 and H2O on the optical properites of pure and polymer encapsulated single walled carbon nanotubes
(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 ...
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 ...
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
(Wiley: Advanced Materials, 1999-11)
