摘要： A hydrogen sensitive composite sensing material based on cerium oxide with or without additives to enhance sensitivity to hydrogen, reduce cross-sensitivities to interfering gases, or lower the operating temperature of the sensor, and a device incorporating these hydrogen sensitive composite materials including a support, electrodes applied to the support, and a coating of hydrogen sensitive composite material applied over the electroded surface. The sensor may have in integral heater. The sensor may have a tubular geometry with the heater being inserted within the tube. A gas sensor device may include a support, electrodes applied to the support, and a dual sensor element to cancel unwanted effects on baseline resistance such as those resulting from atmospheric temperature changes. The hydrogen sensitive composite material or other gas sensitive materials may be used in the dual element gas sensor device.

摘要： A sensor and method of use for detection of low levels of carbon monoxide in gas mixtures. The approach is based on the change in an electrical property (for example: resistance) that occurs when carbon monoxide is selectively absorbed by a film of copper chloride (or other metal halides). The electrical property change occurs rapidly with both increasing and decreasing CO contents, varies with the amount of CO from the gas stream, and is insensitive to the presence of hydrogen. To make a sensor using this approach, the metal halide film will deposited onto an alumina substrate with electrodes. The sensor may be maintained at the optimum temperature with a thick film platinum heater deposited onto the opposite face of the substrate. When the sensor is operating at an appropriate (and constant) temperature, the magnitude of the electrical property measured between the interdigital electrodes will provide a measure of the carbon monoxide content of the gas.
摘要翻译： 用于检测气体混合物中低水平一氧化碳的传感器和方法。 该方法基于当一氧化碳选择性地被氯化铜（或其它金属卤化物）的膜吸收时发生的电性质（例如：电阻）的变化。 随着CO含量的增加和减少，电气性能发生迅速变化，随着气流中CO的含量而变化，并且对氢的存在不敏感。 为了使用这种方法制作传感器，金属卤化物膜将用电极沉积到氧化铝衬底上。 传感器可以保持在最佳温度，而沉积在基板的相对面上的厚膜铂加热器。 当传感器在适当的（和恒定的）温度下运行时，在叉指电极之间测量的电性能的大小将提供气体的一氧化碳含量的量度。

摘要： A method of forming boron nitride nanoparticles. A plurality of precursor molecules comprising boron, nitrogen and hydrogen may be decomposed in a first heating zone to form a plurality of gaseous molecules that contain bonded boron and nitrogen, followed by heating to a second, higher temperature thereby causing the gaseous molecules to react and nucleate to form a plurality of boron nitride nanoparticles. Depending on processing temperatures, the boron nitride nanoparticles may include amorphous forms, crystalline forms, or combinations thereof. Precursor molecules may include ammonia borane, borazine, cycloborazanes, polyaminoborane, polyiminoborane, and mixtures thereof. The boron nitride nanoparticles may be incorporated into a variety of dispersions, composites, and coatings; and in one embodiment, may be a component of a propellant, wherein the boron nitride nanoparticles may confer a range of advantages to gun barrels in which such propellants may be fired.
