  • Metal oxide nanoparticles for smoke clearing and fire suppression
    Patent number: 7661483
    Abstract: Methods of reducing smoke levels in smoke-affected areas, reducing the level of toxic compounds produced by fires, fire suppression, and increasing flame retardancy. In particular, methods according to the present invention comprise dispersing nanocrystalline particles in the areas affected by smoke for sorption of smoke particulates and toxic compounds produced from a fire. The nanocrystalline particles are also effective for use in methods of fire suppression and flame retardancy.
    Type: Grant

  • Method and apparatus for control of chemical or biological warfare agents
    Publication number: 20030215355
    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.
