  • Patent number: 9678221
    Abstract: When a scintillator and a reinforcing member are bonded by using an adhesive, scattering and reflection occur at interfaces between the scintillator and the adhesive and between the adhesive and the reinforcing member. Due to this, a blurred image is formed on a sensor, and the resolution deteriorates. A radiation detecting element comprises: a substrate transparent to visible light; and a fluorescent screen that emits fluorescence in response to radiation by a dopant added to a material that is the same as a material of the substrate, wherein the fluorescent screen is thinner than the substrate, and the substrate and the fluorescent screen are bonded while maintaining continuity of a refractive index.

  • Patent number: 8268269
    Abstract: As population density increases, the transportation of hazardous chemicals, including acids and disinfectants, lead to an increased incidence of spills while the consequences of spills become more serious. While solutions of halide acids, hypohalites and halites are safer disinfectants for transportation, handling, storage and use than traditional gaseous chlorine, the manufacturing cost of these disinfectants has here-to-fore limited their use. Economical processes are presented for the manufacture of O2, halogen oxides, halide acids, hypohalites, and halates; as well as polynucleate metal compounds, metal hydroxides and calcium sulfate hydrate (gypsum). The instant invention presents methods and processes that incorporate the use of sulfur. This is while environmental regulators, such as the US EPA, require an increased removal of sulfur from hydrocarbon fuels, thereby creating an abundance of sulfur, such that the refining industry is in need of a way to dispose of said abundance of sulfur.

The ammonium chloride is then added to the hydrochloric acid solution which is stirred by a stirring mill at the rotation of 200 revolutions per minute or more. The hydrochloric acid solution is held at a temperature of from 85 to 95° C. for 1 hour while being stirred at 200 rpm. The resultant precipitate of ammonium hexachlororuthenate is filtered. The inventive crystals of precipitated ammonium hexachlororuthenate has 10 mass % or less of moisture content.

  • Patent number: 7476376
    Abstract: Disclosed is metal composite oxides having the new crystal structure. Also disclosed are ionic conductors including the metal composite oxides and electrochemical devices comprising the ionic conductors. The metal composite oxides have an ion channel formed for easy movement of ions due to crystallographic specificity resulting from the ordering of metal ion sites and metal ion defects within the unit cell. Therefore, the metal composite oxides according to the present invention are useful in an electrochemical device requiring an ionic conductor or ionic conductivity.

    Abstract: Crystalline scintillator materials comprising nano-scale particles of metal halides are provided. The nano-scale particles are less than 100 nm in size. Methods are provided for preparing the particles. In these methods, ionic liquids are used in place of water to allow precipitation of the final product. In one method, the metal precursors and halide salts are dissolved in separate ionic liquids to form solutions, which are then combined to form the nano-crystalline end product. In the other methods, micro-emulsions are formed using ionic liquids to control particle size.

  • Publication number: 20080131354
    Abstract: A process is provided for the preparation of a novel polyaluminum calcium hydroxychloride composition of enhanced efficiency for water treatment, paper sizing, and antiperspirant applications. The polyaluminum calcium hydroxychloride compositions are prepared via the acidification of higher basicity reaction products to form mid-to-high basicity final products. Two methods are provided for the preparation of higher basicity products, contemplated in the first, and an aqueous acid solution, such as hydrochloric acid, aluminum chloride, or a mixture thereof, is mixed with a strong alkaline calcium salt such as calcium oxide or calcium carbonate and aluminum powder at temperatures greater than 60° C. In a second method, bauxite, aluminum hydrate, or aluminum metal, and calcium aluminate are mixed with hydrochloric acid and are reacted at high temperatures and/or elevated pressures for a certain period of time whereby, when the reaction is complete, the mixtures are filtered to obtain clear solutions.
