20100005858 | Polyaniline Nanofiber-Metal Salt Composite Materials for Arsine Detection - A sensor for detecting arsine includes a pair of electrodes separated by an electrode gap, and a layer of conducting polymer material positioned over and making electrical contact with the pair of electrodes, the layer of conducting polymer material being modified with a metal salt such that the electrical resistance of the conducting polymer material measured across the electrodes is responsive to changes in an amount of arsine to which the conducting polymer material is exposed. | 01-14-2010 |
20100006434 | Polyaniline Nanofiber-Amine Composite Materials for Phosgene Detection - A sensor for detecting phosgene includes a pair of electrodes separated by an electrode gap, and a layer of conducting polymer material positioned over and making electrical contact with the pair of electrodes, the layer of conducting polymer material being modified with an amine such that the electrical resistance of the conducting polymer material measured across the electrodes is responsive to changes in an amount of phosgene to which the conducting polymer material is exposed. | 01-14-2010 |
20100059375 | Metal salt hydrogen sulfide sensor - A hydrogen sulfide sensor is made from a metal acetate film, such as a thin film of copper acetate, formed on a set of monitoring electrodes, by evaporation of a metal acetate aqueous solution disposed on the electrodes, for detecting a weak gas, such as hydrogen sulfide, carried in a gas carrier, such as a nitrogen carrier, for detecting low concentration of the weak gas, such as ten ppm, when the conductivity of the film changes by several orders of magnitude, that produces a metal sulfide, such as copper sulfide, that is a good electrical conductor at room temperature, for example, as the metal acetate is converted directly to a metal sulfide upon exposure to hydrogen sulfide. | 03-11-2010 |
20110287551 | METAL SALT HYDROGEN SULFIDE SENSOR - A sensor made from a metal salt film, formed on a set of monitoring electrodes, by evaporation of a metal salt aqueous solution disposed on the electrodes, is used for detecting a weak acid. Low concentrations of the weak acid, such as ten ppm, are indicated as the conductivity of the film changes by several orders of magnitude, as a result of reaction of the weak acid with the metal salt, as the metal salt converts to a metal reaction product upon exposure to the weak acid. | 11-24-2011 |
20110300637 | Polyaniline Nanofiber Hydrogen Sensors - A method for sensing hydrogen includes the use of a transduction device with a sensing layer, and means for measuring a mass and/or conductivity change caused by an interaction of a gas with the sensing layer to provide a measure of an amount of hydrogen in the gas. The sensing layer includes polyaniline nanofiber material. | 12-08-2011 |
