  • Patent number: 10000714
    Abstract: Aqueous and substantially crystalline iron oxide nanoparticle dispersions and processes for making them are disclosed. The nanoparticle size and size distribution width are advantageous for use in a fuel additive for catalytic reduction of soot combustion in diesel particulate filters. Nanoparticles of the aqueous colloid are transferred to a substantially non-polar liquid comprising a carboxylic acid and one or more low-polarity solvents. The transfer is achieved by mixing the aqueous and substantially non-polar materials, forming an emulsion, followed by a phase separation into a substantially metal-free remnant polar phase and a substantially non-polar organic colloid phase. A method for rapid and substantially complete transfer of non-agglomerated nanoparticles to the low polarity phase in the presence of an organic amine, and a rapid phase separation of the substantially non-polar colloid from a remnant aqueous phase, are provided.

    Abstract: A method of preparing a sol of lead zirconium titanate, known as PZT, of formula PbZrxTi(1?x)O3 with 0.45?x?0.7, comprises the steps of: (a) preparing a concentrated sol in a diol, the sol comprising a titanium-based precursor, a zirconium-based precursor, and a lead-based precursor; (b) placing the concentrated sol at ambient temperature without agitation, until a sol is obtained having a constant viscosity as a function of time; (c) diluting the sol obtained in (b) with a solvent compatible with the diol used in step (a). The sol is useful for preparing PZT-based films for use in the electronics field.

  • Patent number: 7772288
    Abstract: The invention provides a composition that is a dispersion made from a Group III nitride, a solvent system, and a dispersant. The dispersion can be used to prepare Group III nitride thin films on a wide range of substrates, for example, glass, silicon, silicon dioxide, silicon nitride, silicon carbide, aluminum nitride, sapphire, and organic polymers. The particle size of the Group III nitride used for producing the thin films can be controlled by adjusting centrifugation of the dispersion and selecting a desired layer of supernatant. The dispersant can be removed from the thin films by calcination. The Group III nitride can contain a dopant. Doped Group III nitride thin films can emit visible light upon irradiation. Green, red, and yellow light emissions result from irradiating erbium-, europium-, and cerium-doped gallium nitride, respectively.

  • Patent number: 7767720
    Abstract: Single domain wafer-scale colloidal crystals and macroporous polymers are formed by dispersing concentrated solutions of colloids, desirably mondisperse silica colloids, in a viscous monomer, desirably ethoxylated trimethylolpropane triacrylate, and spin-coating them onto a substrate. Subsequent photopolymerization produces three-dimensionally ordered colloidal crystals trapped inside a polymer matrix. Selective removal of the polymer matrix, such as by oxygen plasma treatment, or removal of the silica spheres, such as by wet etching, produces large-area colloidal crystals and macroporous polymers, respectively.

  • Patent number: 7741376
    Abstract: A dispersed ingredient having metal-oxygen bonds which is obtained by hydrolyzing a metal alkoxide in an organic solvent in the absence of an acid, a base, and/or a dispersion stabilizer, either with 0.5 to less than 1 mol of water per mol of the metal alkoxide or at ?20° C. or lower with 1.0 to less than 2.0 mol of water per mol of the metal alkoxide. In the organic solvent, the dispersed ingredient is stably dispersed without aggregating. Use of the dispersed ingredient enables a thin metal oxide film and a homogeneous organic/inorganic composite to be produced at a temperature as low as 200° C. or below.
