摘要： 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.

摘要： An improved, atmospheric pressure process for the production of granular cold water-soluble starches is disclosed which comprises forming a slurry of starch granules, water and polyhydric alcohol (e.g. 1,2-propanediol), heating the slurry to convert the starch crystalline structure to a V-type single helix crystalline arrangement or to an amorphous structure, and thereafter separating the converted, cold water-soluble starch granules from the liquid phase. The process can be used to good effect on cereal, tuber, root and legume starches and on many of their cross-linked and substituted forms to yield cold water-soluble starch granules having cold water-solubilities on the order of 70-95%.

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.
