  • Patent number: 10828873
    Abstract: The present invention relates to a textile composite for the adsorption and breakdown of harmful chemical materials. A support layer and a sorptive and reactive material mounted on the support layer form a protective layer, which is mounted on an inner liner. The protective layer adsorbs and breaks down harmful chemical materials. An outer shell is formed of fabric having an outer surface that is hydrophobic for resisting the passage of harmful chemicals, which may be in the form of vapor, liquid or aerosols. Preferably, the sorptive and reactive material includes zirconium hydroxide, and the support layer includes a fabric material. The zirconium hydroxide is distributed on the fabric material in the amount of at least 20 grams of zirconium hydroxide per square meter. Alternatively, the zirconium hydroxide is distributed in the amount of at least 150 or 200 grams of zirconium hydroxide per square meter.

  • Patent number: 10625239
    Abstract: Provided are mixed metal oxy-hydroxides that serve as reactive media to bind, sequester, or alter one or more toxic chemicals such as sulfur dioxide (SO2), hydrogen cyanide (HCN), and others. A reactive media includes: a porous metal oxy-hydroxide including at least one first transition metal that is optionally one or more of copper, zinc, or iron; a second transition metal linked to the first transition metal by a bond that includes an oxygen, the second transition metal selected optionally being one or more of magnesium, calcium, cobalt, titanium, zirconium, aluminum, and silicon; and the metal oxy-hydroxide terminated by at least one hydroxyl group. The resulting media provides for excellent porosity and reactivity for removal of toxic chemicals from the environment or a sample.

  • Patent number: 9212383
    Abstract: The present disclosure, according to some embodiments, relates to phage-based biological detection systems, compositions, and methods. In some embodiments, it relates to a detection system and method using phage binding and bacterial infection to detect the presence of a target molecule (e.g., a toxin). One detection system may include a genetically engineered phage that expresses a surface molecule able to bind a target molecule and/or target microorganism; a bacterium susceptible to infection by the phage; and a detection component able to determine whether the bacterium has been infected by the phage. Infection of a bacterium by a phage may be indicative of phage binding to the target molecule and/or target microorganism.

  • Publication number: 20140366726
    Abstract: A natural gas-containing stream such as biogas from landfills and sewage treatment plants is freed of siloxane contaminants by passing the biogas through a bed containing an adsorbent having a neutral surface, which adsorbs the siloxanes. When the bed of neutral adsorbent is filled to capacity, the adsorbent bed is heated to remove the siloxanes and regenerate the bed. The neutral adsorbent reduces disadvantageous reactions between the adsorbent and siloxane and other impurities in the natural gas-containing stream.

  • Patent number: 8865399
    Abstract: The present disclosure relates to compositions, methods, systems and kits for the detection of microorganisms of the Yersinia species including Yersinia pestis. The disclosure relates to recombinant phage operable to infect a Yersinia microorganism, the phage comprising a detectable reporter. Detection systems of the disclosure may comprise a phage operable to infect a Yersinia microorganism, and may comprise a reporter nucleic acid expressible upon infection of a Yersinia microorganism by the phage. The system may be operable to detect the expression of the reporter. A detectable reporter may comprise any gene having bioluminescent, colorimetric and/or visual detectability. For example, a detectable reporter may comprise one or more luxAB genes detectable by emission, enhancement and/or change in spectrum of bioluminescent light. Live and infectious Yersinia microbes may be detected by the compositions, methods, systems and kits described herein.
