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 ...
Scanning tunneling optical resonance microscopy (STORM)
(Materials Research Society Proceedings: 2002 Fall Meeting: Symposium G, 2003)
The ability to determine the in-situ optoelectronic behavior of semiconductor materials has become especially important as the size of device architectures are reduced and the development of complex microsystems has ...
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 ...
Carbon nanotube doped lithium ion batteries
(American Physical Society: Proceedings of the Annual APS March Meeting, 2002-03-18)
We have characterized thin film lithium ion batteries that contain high purity single wall carbon nanotube-doped polymer anodes. Highly purified single-walled carbon nanotubes (SWCNT) were obtained through chemical refinement ...
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 ...
Carbon nanotube anodes for lithium ion batteries
(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 ...
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 ...
