    摘要: The invention provides a sorptive sheet material in which finely divided nanocrystalline particles that react with a variety of chemical and/or biological agents are dispersed. The sheet material comprises a fibrous web that is formed of a plurality of fibers that are bonded to each other. The fibrous web contains a relatively high concentration of reactive nanocrystalline particles that are entrapped within the matrix of the fibrous web. Fluids containing toxic agents, such as chemical and/or biological agents, odors and/or odor causing compounds, and toxic industrial compounds, pass into the web and contact the reactive nanocrystalline particles contained therein. The reactive nanocrystalline particles react with, and chemically alter or inactivate the toxic agents. The sorptive sheet material may be used to construct containers, such as remains pouches, for the storing and transporting of contaminated items, particularly human remains.

    摘要: Compounds and methods for sorbing organosulfur compounds from fluids are provided. Generally, compounds according to the present invention comprise mesoporous, nanocrystalline metal oxides. Preferred metal oxide compounds either exhibit soft Lewis acid properties or are impregnated with a material exhibiting soft Lewis acid properties. Methods according to the invention comprise contacting a fluid containing organosulfur contaminants with a mesoporous, nanocrystalline metal oxide. In a preferred embodiment, nanocrystalline metal oxide particles are formed into pellets (14) and placed inside a fuel filter housing (12) for removing organosulfur contaminants from a hydrocarbon fuel stream.

    摘要: Metal oxide area decontamination apparatus (10) is provided which is designed for rapid, emergency situation decontamination of areas contaminated with potentially harmful or lethal chemical and/or biological warfare agents or other hazardous substances. The apparatus (10) preferably includes a pressurizable metallic container (12) equipped with a valve-type delivery nozzle assembly (16), so that upon a manipulation of the assembly (16), a spray of metal oxide and/or metal hydroxide particles is generated; the particles are selected and sized in order to destroy or chemisorb the contaminating agents. The preferred decontamination agent is MgO aggregated to an average aggregate size of from about 50 nm-10 microns. The particles are mixed with a gaseous or liquid propellant within the container (12) allowing rapid and thorough particle cleanout when the nozzle assembly (16) is actuated.
