For example, the nickel particulate form can have a BET Specific Surface Area of at least about 1 m2/gm; an average crystallite size less than about 20-25 nm, the nickel particulate form can have at least 10% of the crystallites in the nickel form can have can have a diameter (C10) of less than about 10 nm, and/or there are on average at least about 1015 surface crystallites per gram nickel. A ratio of BET SSA to C50 for the nickel particulate form can be at least about 0.1×109 m/gm and preferably at least about 0.4×109 m/gm. Methods of preparation and use are also provided.

  • Publication number: 20130096314
    Abstract: A method for preparing a ruthenium carbene complex precursor includes reacting a ruthenium refinery salt with a hydrogen halide to form a ruthenium intermediate, and reacting the ruthenium intermediate with an L-type ligand to form the ruthenium carbene complex precursor. A method for preparing a ruthenium vinylcarbene complex includes converting a ruthenium carbene complex precursor into a ruthenium hydrido halide complex, and reacting the ruthenium hydrido halide complex with a propargyl halide to form the ruthenium vinylcarbene complex. A method for preparing a ruthenium carbene complex includes converting a ruthenium carbene complex precursor into a ruthenium carbene complex having a structure (PR1R2R3)2Cl2Ru?CH—R4, wherein R1, R2, R3, and R4 are alike or different, and wherein covalent bonds may optionally exist between two or more of R1, R2, and R3 and/or two of R1, R2, and R3 taken together may optionally form a ring with phosphorous.

  • Publication number: 20130035498
    Abstract: This invention provides a semiconductor having a functionalized surface that is resistant to oxidation and that includes a plurality of atoms of a Group III element bonded to organic groups. The functionalized surface has less than or equal to about 1 atom of the Group III element bonded to an oxygen atom per every 1,000 atoms of the Group III element bonded to the organic groups, as determined using X-ray photoelectron spectroscopy. This invention also provides a method of functionalizing the surface and includes the step of halogenating at least one of the plurality of atoms of the Group III element to form halogenated Group III element atoms. The method also includes the step of reacting at least one of the halogenated Group III element atoms with a Grignard reagent to form a bond between the at least one Group III element atom and the organic groups.

  • Patent number: 8350072
    Abstract: The invention provides a method for producing soluble neodymium chloride complex using neodymium chloride aqueous solution as raw material, thereby avoiding the use of anhydrous neodymium chloride, simplifying the synthesis process and reducing the cost for synthesizing neodymium chloride complex. The neodymium chloride complex produced by this method is soluble not only in polar solvent, but also in nonpolar solvent. Such neodymium chloride complex also has good dissolvability in aliphatic hydrocarbon solvent which has relatively weaker solution power, and even in aliphatic hydrocarbon solvent with 6 or less carbon atoms which has even lower solution power. Since neodymium chloride complex is soluble in aliphatic hydrocarbon solvent, its transportation may be conducted, which is convenient for industrial application and contributes to improve the utilization efficiency of rare earth.
