  • Patent number: 9184439
    Abstract: Providing a noble negative-electrode active material including silicon, and a production process for the same. A negative-electrode active material for non-aqueous-system secondary battery including a silicon phase and a composite oxide phase (a CaSiO3 phase, for instance) is obtained by mixing a silicon oxide (SiO, for instance) with a silicon compound (CaSi2, for instance), which includes silicon and at least one member of elements being selected from the group consisting of Group 2 (or Group 2A) elements in the Periodic Table, to prepare a mixed raw material, and then reacting the mixed raw material. The composite oxide phase demonstrates the advantage of inhibiting electrolytic solutions from decomposing in a smaller amount than does the conventional SiO2 phase.

  • Publication number: 20150045248
    Abstract: The present invention aims to develop and provide a method for identifying a disease associated with the abundance of TDP-43 in cells and a method for producing a TDP-43 binding inhibitor. By measuring the abundance of a measurement substance, the amount of binding between a measurement substance and TDP-43, etc. in cells obtained from a subject, it is identified whether or not the subject is suffering from a disease associated with the abundance of TDP-43 in cells. Also, a drug which can significantly reduce the binding between a measurement substance and TDP-43 is produced by adding a drug candidate substance.
