  • Publication number: 20160279456
    Abstract: Provided is a polychlorinated biphenyl-decomposing composition obtained according to a method comprising respectively culturing at least one main microbial strain belonging to Comamonas species and having biphenyl dioxygenase, and at least one complementary microbial strain selected from the group consisting of Pseudomonas species, Achromobacter species, Rhodococcus species and Stenotrophomonas species and having biphenyl dioxygenase, and mixing at least two types of microbial cells recovered from each of the culture media. A composition containing these compounded microorganisms is useful for efficiently decomposing or detoxifying comparatively low concentrations of PCBs present in large amounts in waste products contaminated with polychlorinated biphenyls.

  • Patent number: 9373823
    Abstract: In a coating-type electron injection layer or electron transport layer using a metal oxide, the present invention aims at improving uniformity or stability of composition distribution and adhesion with another adjoining constituent layer, and improving film forming property, to thereby provide an organic electronic device and manufacture of the device whose efficiency is improved. In the organic electronic device having one pair of electrodes on a substrate, and having at least one organic layer between the electrodes, the electron injection layer or the electron transport layer is formed by application of a liquid material in which an alkaline metal salt and zinc-oxide nano particles are dissolved in alcohol.

  • Publication number: 20150231698
    Abstract: The invention provides a novel and non conventional process for producing coated silver fine particles by the so-called amine complex decomposition process, and also provides coated silver fine particles produced by the process. The process includes a first step of forming a complex compound including a silver compound and an alkylamine by mixing (1) a silver compound capable of generating metal silver by thermal decomposition, (2) an alkylamine, and (3) at least one alcoholic compound having a solubility in water and/or a compound having at least one of a carbon-heteroatom multiple bond and a heteroatom-heteroatom multiple bond in the molecule, and a second step of generating silver fine particles coated with a protecting layer including the alkylamine by thermal decomposition of the complex compound.
