  • Patent number: 8822697
    Abstract: The present invention relates to a paramagnetic polynuclear metal complex having enhanced self-relaxation rate and thermodynamic stability, and more particularly, to a synthetic method of a novel DTPA-bis-amide-histidine ligand and DTPA-bis-amide-aspartic acid ligand, a novel gadolinium complex ([Gd(L)H2O]) using the ligand, and a paramagnetic polynuclear metal complex using the gadolinium complex. The paramagnetic polynuclear metal complex is able to fix three or more metals (one gadolinium and two metal ions), thereby providing more excellent self-relaxation rate than the commercially available contrast agents. Thus, it can be widely applied to an MRI contrast agent because of meeting the high self-relaxation rate required as a contrast agent of magnetic resonance imaging (MRI).

    Abstract: Disclosed is a clean method for preparing layered double hydroxides (LDHs), in which hydroxides of different metals are used as starting materials for production of LDHs by atom-economical reactions. The atom efficiency of the reaction is 100% in each case because all the atoms of the reactants are converted into the target product since only M2+(OH)2, M3+(OH)3, and CO2 or HnAn? are used, without any NaOH or other materials. Since there is no by-product, filtration or washing process is unnecessary. The consequent reduction in water consumption is also beneficial to the environment.

  • Patent number: 6297392
    Abstract: A novel Group IV elements-bridged metallocene complex is disclosed which is represented by the following formula (I): wherein R and R1 are different and are independently selected from the group consisting of &eegr;5-cyclopentadienyl group, substituted &eegr;5-cyclopentadienyl group, indenyl group, and fluorenyl group; R2 is selected from the group consisting of —N(CH3)2, —N(C2H5)2, halogen, alkoxy, —(C═O)NH2, and C6-12 hydrocarbyl group; M is a Group IVA element; and M1 is a Group IVB metal. When employing the metallocene complex to prepare olefin polymers, since it is bridged by a Group IV element, there are two catalytic sites in the single metallocene complex catalyst. Therefore, the olefin monomers can be polymerized to a bimodal olefin polymer by a single catalyst in a single reactor, resulting in lowered capital costs.

  • Patent number: 6096693
    Abstract: The present invention is directed to a zinc-molybdenum-based dithiocarbamate derivative which is a complex salt having the metallic components of zinc and molybdenum in the same molecule. When used as a lubricant additive, it imparts a notable friction-reducing effect to the lubricant composition in which it is incorporated, reducing its friction coefficient and improving its stability of friction coefficient at both low and high temperature, particularly at high temperature. In particular, it improves friction-related characteristics much more notably than a combination of a molybdenum and zinc compound.

  • Patent number: 5612082
    Abstract: Metals are reacted in a first solvent, such as 2-methoxyethanol, to form an initial precursor comprising metal-oxide compounds dissolved in the first solvent. A second solvent, such as xylene, that does not react with the metal is added to the solution and the solution heated to distill away the first solvent and form a final precursor. The final precursor is spin-coated on an integrated circuit substrate then dried and annealed to form a thin film of a metal oxide. For metal oxides including bismuth, the bismuth precursor is added to a cold initial precursor and the final precursor is not heated after the bismuth precursor is added. The second solvent wets the substrate better than the first solvent and has a better viscosity for spin-coating, thus resulting in a denser thin film with fewer imperfections.

  • Patent number: 5583243
    Abstract: Novel salts are prepared wherein the cation of the salt is a divalent or trivalent cation which is an essential trace element comprising a 1:1 ratio of a complex ion formed between a trace mineral and methionine and any suitable anion, either inorganic or organic. The novel salts have the generic formula: ##STR1## Wherein R.sub.1 is methyl or ethyl, R.sub.2 is hydrogen, methyl or ethyl, R.sub.3 is hydrogen or methyl, M is a covalent or trivalent trace mineral cation, X is an anion and w is an integer to balance the anionic charge of X. These novel compounds are useful nutritional supplements, both for animals and humans, in that they provide a readily available source of a highly water soluble methionine which is an essential amino acid.

  • Patent number: 5559260
    Abstract: A precursor is made by mixing a metal alkoxycarboxylate-containing liquid with a 2-ethylhexanoic acid in an effective amount for shelf-stabilizing said liquid by substituting 2-ethylhexanoate ligands for alkoxide ligands, thereby forming a mixture, and heating said mixture to substitute said carboxylate ligands for said alkoxide ligands. Specficially, a barium strontium titanate precursor and a strontium bismuth tantalate precursor are made by combining polyoxyalkylated metal moieties to form a liquid solution in which the metal atoms bond with an oxygen atom in a ligand selected from a ligand group consisting of alkoxides and carboxylates, then then heating the liquid solution.
