  • Publication number: 20240014448
    Abstract: Electrochemical cells are provided, wherein a metal ion is adsorbed to a manganese dioxide- or carbon-containing electrode due to the addition of a metal additive to the cell's electrolyte and/or cathode. Methods for preparing such cells are also provided. In particular embodiments, the electrochemical cells are alkaline electrochemical cells, and the electrode contains manganese dioxide.
    Type: Application

  • Patent number: 8456313
    Abstract: This invention is a nuclear radiation-warning detector that measures impedance of silver-silver halide on an interdigitated electrode to detect light or radiation comprised of alpha particles, beta particles, gamma rays, X rays, and/or neutrons. The detector is comprised of an interdigitated electrode covered by a layer of silver halide. After exposure to alpha particles, beta particles, X rays, gamma rays, neutron radiation, or light, the silver halide is reduced to silver in the presence of a reducing solution. The change from the high electrical resistance (impedance) of silver halide to the low resistance of silver provides the radiation warning that detected radiation levels exceed a predetermined radiation dose threshold.
