摘要:A method for synthesis of high anisotropy L10 FeNi (tetrataenite) thin films is provided that combines physical vapor deposition via atomic layer sputtering and rapid thermal annealing with extreme heating and cooling speeds. The methods can induce L10-ordering in FeNi thin films. The process uses a base composite film of a support substrate, a seed layer, a multilayer thin film of FeNi with alternating single atomic layers of Fe and Ni that mimics the atomic plane of the final L10 FeNi alloy, and a capping layer. The Fe and Ni bilayers are grown on top of a Si substrate with a thermally oxidized SiO2 seed layer to mechanically strain the sample during rapid thermal annealing.

发明人：WEBB STEVEN P; MCINTYRE JAMES A
权利人:DOW CHEMICAL CO
摘要:This invention is a composite membrane for chemical synthesis, a chemical reactor into which the composite membrane might be incorporated, and a method of using the composite membrane. The composite membrane comprises a substrate, a first side, and a second side, wherein the substrate operatively connects the first side and second side, the first side comprises an oxidizing catalyst and the second side comprises a reducing catalyst. The reducing catalyst comprises, in elemental or combinative form, lanthanum, zinc, cerium, praeseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, bismuth, or indium. A chemical reactor utilizing this composite membrane can react hydrogen and oxygen to form hydrogen peroxide without direct mixture of the reactants.

标 题 :Process for synthesis of uniform colloidal particles of rare earth oxides
发明人：MATIJEVIC EGON

摘要:An improved process for the preparation of monodispersed spherical colloidal particles from rare earth salts. These colloidal particles are obtained in this process by homogeneous precipitation techniques involving the forced hydrolysis of rare earth salts in aqueous media. More specifically, this process initially involves the formation of hydrolyzed cations which are precursors or intermediate to precipitation of the desired colloidal particle. The objective in the formation of this precursor species is to reach critical supersaturation concentration of this particle forming species so that only one burst of nuclei occurs. Colloidal particle formation is then effected by diffusion of solutes onto the existing nuclei. The improvements of this process reside, in part, in the ability to control the kinetics of formation of this intermediate species. Such control permits the formation of colloidal dispersions having very narrow particle size distribution. The colloidal dispersions of these particles are also quite stable. The rare earth colloidal particles prepared by this process are useful in both industrial and biologic environments.

摘要:The present invention relates to methods and apparatus for activation of a low reactivity, non-polar chemical compound. In one example embodiment, the method comprises introducing the low reactivity chemical compound to a catalyst. At least one of (a) an oxidizing agent or a reducing agent and (b) a polar compound is provided to the catalyst and the chemical compound. An alternating current is applied to the catalyst to produce an activation reaction in the chemical compound. This activation reaction produces a useful product. The present invention also relates to a method for oxidizing aromatic compounds by electrocatalysis to oxidized products.
