Abstract: A carbon nanotube (CNT) attraction material is deposited on a substrate in the gap region between two electrodes on the substrate. An electric potential is applied to the two electrodes. The CNT attraction material is wetted with a solution defined by a carrier liquid having carbon nanotubes (CNTs) suspended therein. A portion of the CNTs align with the electric field and adhere to the CNT attraction material. The carrier liquid and any CNTs not adhered to the CNT attraction material are then removed.

Abstract: The invention described herein involves a novel approach to the production of oxidation/reduction catalytic systems. The present invention serves to stabilize the tin oxide reducible metal-oxide coating by co-incorporating at least another metal-oxide species, such as zirconium. In one embodiment, a third metal-oxide species is incorporated, selected from the group consisting of cerium, lanthanum, hafnium, and ruthenium. The incorporation of the additional metal oxide components serves to stabilize the active tin-oxide layer in the catalytic process during high-temperature operation in a reducing environment (e.g., automobile exhaust). Moreover, the additional metal oxides are active components due to their oxygen-retention capabilities. Together, these features provide a mechanism to extend the range of operation of the tin-oxide-based catalyst system for automotive applications, while maintaining the existing advantages.

Abstract: This invention relates generally to a ruthenium stabilized oxidation-reduction catalyst useful for oxidizing carbon monoxide, and volatile organic compounds, and reducing nitrogen oxide species in oxidizing environments, substantially without the formation of toxic and volatile ruthenium oxide species upon said oxidizing environment being at high temperatures.

Abstract: A sensor has a plurality of carbon nanotube (CNT)-based conductors operatively positioned on a substrate. The conductors are arranged side-by-side, such as in a substantially parallel relationship to one another. At least one pair of spaced-apart electrodes is coupled to opposing ends of the conductors. A portion of each of the conductors spanning between each pair of electrodes comprises a plurality of carbon nanotubes arranged end-to-end and substantially aligned along an axis. Because a direct correlation exists between resistance of a carbon nanotube and carbon nanotube strain, changes experienced by the portion of the structure to which the sensor is coupled induce a change in electrical properties of the conductors.

Abstract: A light sensor substrate comprises a base made from a semi-conductive material and topped with a layer of an electrically non-conductive material. A first electrode and a plurality of carbon nanotube (CNT)-based conductors are positioned on the layer of electrically non-conductive material with the CNT-based conductors being distributed in a spaced apart fashion about a periphery of the first electrode. Each CNT-based conductor is coupled on one end thereof to the first electrode and extends away from the first electrode to terminate at a second free end. A second or gate electrode is positioned on the non-conductive material layer and is spaced apart from the second free end of each CNT-based conductor. Coupled to the first and second electrode is a device for detecting electron transfer along the CNT-based conductors resulting from light impinging on the CNT-based conductors.

Abstract: This invention relates generally to a stabilization mechanism for use in oxidation/reduction catalyst systems. It particularly relates to a ruthenium stabilization mechanism that enables the use of inexpensive metallic species within catalyst systems targeted for the elimination of toxic emissions such as carbon monoxide, hydrocarbons, and other volatile organics, and specifically nitrogen oxide species. Said stabilization mechanism includes the use of zirconium-oxides in an oxidation-reduction catalyst.

Abstract: A method and device for visually detecting crack length of a temperature sensitive paint coated test structure during excitation of the test structure. The method and device of the invention capitalizes on surface temperature changes of the test structure as structural fatigue increases. Test structure surface temperature changes are realized in corresponding fluorescence intensity changes in the temperature sensitive paint and recorded with a CCD camera. Improvements over conventional structural fatigue systems include the ability to detect fatigue during flight testing, to record fatigue without stopping the electrodynamic excitation and the ability to detect crack onset and crack length resulting in more accurate cycles-to-fatigue analysis.

The detector is spaced from and substantially across from the portion of the light emitting diode coated with the sol-gel-derived film. The system may include a filter which is located between the light emitting diode and the detector and a processing system which is coupled to the detector for quantifying the amount of a gaseous species or an analyte in a sample based on data from the detector.
