Patent number: 9095838Abstract: An improved air purification adsorbent is disclosed. The air purification adsorbent comprises titanium dioxide (TiO2) impregnated with zinc chloride (ZnCl2). The adsorbent may be used in air purification systems for removing ammonia from air streams. The nanocrystalline (amorphous) structure of the adsorbent results in a higher density of surface defects, higher surface area, and higher reactivity which, when combined with the synergistic effect of ZnCl2 and the nanocrystalline TiO2, provides a significantly longer breakthrough time of ammonia as compared with breakthrough time from unimpregnated nanocrystalline TiO2, the commercial (crystalline) TiO2 impregnated with ZnCl2, pure ZnCL2, and other commercially available adsorbents of ammonia. Other embodiments are described and claimed.Type: GrantFiled: July 18, 2013Date of Patent: August 4, 2015Inventors: Brandon W. Walker, Olga B. Koper, Slawomir Winecki, Christopher L. Aikens, Amy Elizabeth Quiring, Maciej Stanislaw Matyjaszczyk, Martin Keller

Patent number: 9039817Abstract: To achieve the removal of a broad spectrum of chemical hazards, multiple layers of impregnated activated carbon and nanocrystalline materials are incorporated into the adsorbent bed. For optimum performance using the least amount of material, a two-layer configuration is used. The top layer consists of a homogeneous mixture of an MgO/CaO based nanocrystalline material (e.g., Mg/Ca) and Kureha or other petroleum pitch-based bead shaped activated carbon impregnated treated with phosphoric acid. The bottom layer is comprised of a single layer of Calgon URC carbon. The volume ratios of the components are 9:5:11 Mg/Ca, phosphoric acid treated Kureha carbon, and URC, respectively. The new configuration leads to a 30% reduction in size of the existing NIOSH CBRN CAP 1 cartridge. Other embodiments are disclosed and claimed.Type: GrantFiled: July 18, 2013Date of Patent: May 26, 2015Inventors: Christopher L. Aikens, Olga B.

Patent number: 6887302Abstract: Compositions and methods for destroying chemical and biological agents such as toxins and bacteria are provided wherein the substance to be destroyed is contacted with finely divided metal oxide nanoparticles. The metal oxide nanoparticles are coated with a material selected from the group consisting of surfactants, waxes, oils, silyls, synthetic and natural polymers, resins, and mixtures thereof. The coatings are selected for their tendency to exclude water while not excluding the target compound or adsorbates. The desired metal oxide nanoparticles can be pressed into pellets for use when a powder is not feasible. Preferred metal oxides for the methods include MgO, SrO, BaO, CaO, TiO2, ZrO2, FeO, V2O3, V2O5, Mn2O3, Fe2O3, NiO, CuO, Al2O3, SiO2, ZnO, Ag2O, the corresponding hydroxides of the foregoing, and mixtures thereof.Type: GrantFiled: May 1, 2003Date of Patent: May 3, 2005Assignee: NanoScale Materials, Inc.Inventors: Shyamala Rajagopalan, Olga B. Koper, Kenneth J. Klabunde, Paul S. Malchesky, Slawomir Winecki
