  • Publication number: 20140093779
    Abstract: An object of the present invention is to provide a negative-electrode active material for lithium-ion secondary battery, negative-electrode active material which makes it possible for lithium-ion secondary batteries to exhibit higher capacities, and which makes it feasible to charge and discharge lithium-ion secondary batteries at a faster speed. In a production process according to the present invention, oxidized titanium fluoride is obtained by heating a mixed raw material, which includes a mixture of anatase-type TiO2 and hydrofluoric acid, at 70° C. or more (i.e., a heating step). This mixed raw material includes hydrogen fluoride in an amount exceeding 2 mol per the anatase-type TiO2 making 1 mol. When the oxidized titanium fluoride, which is obtained by this production process, is used as a negative-electrode active material of lithium-ion secondary battery, high-capacity and rapidly-chargeable/dischargeable lithium-ion secondary batteries are obtainable.

  • Patent number: 8415163
    Abstract: Disclosed is a method of diagnosing renal dysfunction in a cat by removing cauxin from cat urine and detecting a protein in the cat urine sample from which cauxin has been removed. Cauxin is removed from cat urine by bringing the cat urine into contact with a lectin or with an anti-cauxin antibody that specifically binds to cauxin. Cauxin may be removed using a column filled with a carrier that is bound to the lectin or to the anti-cauxin antibody. The lectin may be Lens culinaris lectin. Detection of the cat urinary protein from which cauxin has been removed is performed with a urine test strip.
