    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： Compositions and methods for destroying biological agents and toxins such as Aflatoxins, Botulinum toxins, and Clostridium perfrigens toxins are provided wherein the substance to be destroyed is contacted with a finely divided metal oxide nanocrystals. In various embodiments, the metal oxide nanocrystals have reactive atoms stabilized on their surfaces, species adsorbed on their surfaces, or are coated with a second metal oxide. The desired metal oxide nanocrystals can be pressed into pellets for use when a powder is not feasible. The methods of the invention are safe for humans, equipment, and the environment, and provide for decontamination of warfare sites, of equipment exposed to the contaminant, and of soil, water and air having been exposed to the contaminant. Preferred metal oxides for the methods include MgO, CaO, TiO2, ZrO2, FeO, V2O5, Mn2O3, Fe2O3, NiO, CuO, Al2O3, ZnO and mixtures thereof. Preferred reactive atoms stabilized on the surfaces of the metal oxide nanocrystals include halogens and Group I metals, and preferred species stabilized on the surfaces of the metal oxide nanocrystals include SO2, NO2 and ozone.
