  • Publication number: 20110297879
    Abstract: A packaged reactive material includes a reactive material that is configured to increase in size when exposed to a predetermined gas, and an inert coating material surrounding a surface of the reactive material. The inert coating material is configured to allow the predetermined gas to diffuse through to the reactive material and has an elongation that will not accommodate expansion of the reactive material at full saturation of the predetermined gas.

  • Publication number: 20110293940
    Abstract: A method for producing coated, fine metal particles each having a Ti oxide coating and a silicon oxide coating formed in this order on a metal core particle by mixing powder comprising TiC and TiN with oxide powder of a metal M meeting the relation of ?GM-O>?GTiO2, wherein ?GM-O represents the standard free energy of forming an oxide of the metal M; heat-treating the resultant mixed powder in a non-oxidizing atmosphere to reduce the oxide of the metal M with the powder comprising TiC and TiN, while coating the resultant metal M particles with Ti oxide; coating the Ti-oxide-coated surface with silicon oxide; and classifying the resultant particles such that they have a median diameter d50 of 0.4-0.7 ?m, and a variation coefficient (=standard deviation/average particle size) of 35% or less, which indicates a particle size distribution range.

  • Publication number: 20110287259
    Abstract: The invention describes a nanocomposite particle comprising a nanoparticle having a surface comprising a silver salt, and at least one region of metallic gold on said surface. The invention also provides a nanocomposite material comprising said particles and processes for making the nanocomposite material, either by allowing gold in nanoparticles having a silver salt on the surface thereof to at least partially diffuse through the silver salt so as to form at least one region of metallic gold on said surface, or else by depositing metallic gold on the surfaces of nanoparticles having the silver salt on the surface thereof.

  • Patent number: 8062703
    Abstract: A method of producing nanoparticles comprises effecting conversion of a nanoparticle precursor composition to the material of the nanoparticles. The precursor composition comprises a first precursor species containing a first ion to be incorporated into the growing nanoparticles and a separate second precursor species containing a second ion to be incorporated into the growing nanoparticles. The conversion is effected in the presence of a molecular cluster compound under conditions permitting seeding and growth of the nanoparticles.
