摘要： Sensing a gas includes introducing a gas into a chamber, forming a standing acoustic wave in the chamber, and irradiating the chamber with electromagnetic radiation. Some of the electromagnetic radiation passes into the chamber, through the standing acoustic wave in the chamber, and out of the chamber. An amount of electromagnetic radiation that passes out of the chamber, or is transmitted through the chamber, is detected. A concentration of the gas in the chamber can be assessed.

摘要： The present invention is directed to assemblies of catalyst material on support material that function to reduce NOx to N2 and O2 at appropriate temperatures. The present invention is also directed to the manufacture and use of such assemblies. Such assemblies improve upon the prior art in that they utilize metal nanoparticles on nanostructured carbon fiber supports. The use of such nanoscale components affords greater catalytic activity per catalyst amount by virtue of the much greater surface area of both the catalyst and the support.

摘要： An apparatus and method for detection of methane in an environment, including a housing with a sensor printed circuit board and a processor printed circuit board interconnected to and thermally insulated from the sensor printed circuit board. The sensor printed circuit board includes a first tuning fork isolated from the environment, and a second tuning fork exposed to the environment. The tuning forks are attached to opposite sides of the sensor printed circuit board. The processor printed circuit board includes processing circuitry interconnected to the first tuning fork and the second tuning fork, which receives vibration frequency signals therefrom, and is programmed to determine a frequency difference between the frequency of vibration of the first tuning fork and the frequency vibration of the second tuning fork, and if the frequency difference is greater than a predetermined threshold, then setting an alarm to indicate the presence of methane.
