  • Patent number: 9289155
    Abstract: Disclosed is a method and device for detection of H. Pylori in breath emissions utilizing an unlabelled urea, in which a patient ingests a safe quantity of unlabelled urea. After ingestion, expired breath of the patient is analyzed for ammonia, with a detection based on levels of ammonia lower than 50 parts per billion to 500 ppm to detect helicobacter pylori.

  • Publication number: 20150129472
    Abstract: Cellulose acetate or polyvinylpyrrolidone is electrospun into fibers having diameters of nanometer scale to form a first mat that is capable of absorbing hydrocarbons. A second mat may be formed from a solution of cellulose acetate or polyvinylpyrrolidone further containing tungsten trioxide. The solution is electrospun onto a copper mesh and then thermally oxidized to create a nanostructure comprising a grid or network of tungsten trioxide crystals and copper oxide crystals. The nanogrid is capable of photocatalyzing the degradation of hydrocarbons to carbon dioxide and water. The grid may be combined with the first mat to degrade hydrocarbons that the first mat absorbs.

  • Patent number: 8955367
    Abstract: Reliable, fast and inexpensive breath gas detector systems for medical diagnostics, including personal, handheld monitoring devices for a variety of diseases and conditions, including, for example, asthma, diabetes, blood cholesterol, and lung cancer. A sensor device (100) for detecting gases includes a sensing element (109) having an electrical resistance that changes in the presence of a target gas; a readout circuit, electrically coupled to the sensing element due to the presence of the target gas and converts the measurement to a digital signal; and a feedback loop (203) from a digital unit (205) to the readout circuit to compensate for variations in a baseline resistance of the sensing element.

  • Publication number: 20120094124
    Abstract: Single crystal MoO3 nanowires were produced using an electrospinning technique. High resolution transmission electron microscopy (HRTEM) revealed that the 1-D nanostructures are from 10-20 nm in diameter, on the order of 1-2 ?m in length, and have the orthorhombic MoO3 structure. The structure, crystallinity, and sensoric character of these electrostatically processed nanowires are discussed. It has been demonstrated that the non-woven-network of MoO3 nanowires exhibits higher sensitivity and an n-type response to NH3 as compared to the response of a sol-gel based sensor.

  • Patent number: 6689322
    Abstract: The present invention includes free-standing, shaped ceramic-bearing bodies useful in fluid sensors, filters, and catalyst devices. The invention also includes methods and processes for using such devices. In a preferred embodiment of the invention, shaped metallic foils are converted into free-standing, porous rutile foils having an open pore structure by oxidation at an elevated temperature. The exposure of such foils to increasing concentrations of reducing gases such as carbon monoxide results in an increase in the steady-state electrical resistance. The resultant ceramic-bearing bodies may be used as effective sensors of reducing gas species in such applications as automobile and industrial emissions.
