  • Patent number: 12098463
    Abstract: A method for manufacturing an amorphous multielement metal oxide hydroxide film includes: A liquid mixture is formed by dissolving an oxidizing agent selected from a group consisting of potassium permanganate, potassium chromate, potassium dichromate and potassium ferrate, and a reducing agent in a solvent. The oxidizing agent forms an oxometallate anion having a first metal atom with a first valence number. The reducing agent forms a metal cation having a second metal atom with a third valence number. An amorphous multielement metal oxide hydroxide film is deposited on a substrate by soaking the substrate in the liquid mixture. The amorphous multielement metal oxide hydroxide film includes a multielement metal oxide hydroxide having the first metal atom with a second valence smaller than the first valence number and the second metal atom with a fourth valence number larger than the third valence number.

  • Publication number: 20200199756
    Abstract: A method for depositing a metal oxide film in a liquid environment is provided, and includes steps of: dissolving an oxidizing agent in solvent with hydrogen bond to form a solution, and placing a substrate into the solution for performing a deposition reaction to deposit a metal oxide hydroxide film on the substrate. The oxidizing agent is potassium permanganate, potassium chromate, or potassium dichromate, a reaction temperature of the deposition reaction ranges from 1 to 99 degrees Celsius, and a reaction pressure environment of the deposition reaction is an atmospheric pressure environment.

  • Publication number: 20070153973
    Abstract: A method and system for determining the bone mineral density of a body extremity. An image of a body extremity is acquired using a mammography x-ray system whereby a bone mineral density can be performed on the image. The system for determining the bone mineral density of a body extremity includes: a support for supporting the body extremity; a detector for capturing an image of the body extremity; and an x-ray source adapted to project an x-ray beam through the body extremity toward the detector, the x-ray source having a voltage of no more than about 45 kVp and having a target/filter combination of rhodium/rhodium, molybdenum/molybdenum, molybdenum/rhodium, or tungsten/rhodium.
