  • Copper-manganese mixed oxide cathode material for use in alkaline cells having high capacity
    Patent number: 7807296
    Abstract: The present invention relates to a copper-manganese mixed oxide cathode material, which is suitable for use in a cathode of an electrochemical cell, and which has the formula MnxCuyOz.nH2O, wherein the oxidation state of Cu is between about +1 and about +3, the oxidation state of Mn is between about +2 and about +7, x is equal to about 3-y, y is less than about 3, z is calculated or experimentally determined, using means known in the art, based on the values of x and y, as well as the oxidation states of Mn and Cu, and nH2O represents the surface and structural water present in the mixed oxide material. The present invention further relates to an electrochemical cell comprising the noted cathode material.

  • Laser-induced breakdown spectroscopy for specimen analysis
    Patent number: 7092087
    Abstract: The present invention is directed to an apparatus, a system and a method for detecting the presence or absence of trace elements in a biological sample using Laser-Induced Breakdown Spectroscopy. The trace elements are used to develop a signature profile which is analyzed directly or compared with the known profile of a standard. In one aspect of the invention, the apparatus, system and method are used to detect malignant cancer cells in vivo.
