Abstract: The present invention relates to methodologies for the self-assembly of nanoparticles onto a release support that is capable of covalent integration into flexible free-standing films. Such films display usefull constitutive properties, such as permittivity, permeability, electrical conductivity, thermal conductivity, and nonlinear optic properties. The type of property is dependant upon the type of nanoparticle incorporated into the compliant polymeric matrix. The compliant matrix may be any material that reacts with the components in the nanoparticle film and may be separated from the release substrate. The nanoparticles may be dispersed uniformly or spatially patterned throughout the self-assembled film.

Abstract: 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.

Abstract: A method for removing at least one contaminant selected from the group consisting of H2S and CO2 from contaminating streams, including the steps of providing an above ground stream comprising hydrocarbon containing the at least one contaminant, and positioning metal-containing nanoparticles having a particle size of less than or equal to about 100 nm in the stream, the metal-containing nanoparticles being selected from the group consisting of metal oxides, metal hydroxides and combinations thereof, whereby the nanoparticles adsorb the contaminants from the stream.

Abstract: Compositions and methods for destroying biological agents such as toxins and bacteria are provided wherein the substance to be destroyed is contacted with finely divided metal oxide or hydroxide nanocrystals. In various embodiments, the metal oxide or metal hydroxide 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 or metal hydroxide nanocrystals 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, [Ce(NO3)3—Cu(NO3)2]TiO2, Mg(OH)2, Ca(OH)2, Al(OH)3, Sr(OH)2, Ba(OH)2, Fe(OH)3, Cu(OH)3, Ni(OH)2, Co(OH)2, Zn(OH)2, AgOH, and mixtures thereof.

Abstract: 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.

Abstract: 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.

Abstract: A topical skin protectant formulation containing a barrier cream and a active moiety for protecting warfighters and civilians against all types of harmful chemicals, specifically chemical warfare agents (CWAs). The topical skin protectant offers a barrier property and an active moiety that serves to neutralize chemical warfare agents into less toxic agents.
