  • Patent number: 10276892
    Abstract: Solid electrolytes compositions, methods of making the solid electrolytes, and methods of using the solid electrolytes in batteries and other electrochemical technologies are disclosed. The method of producing a solid electrolyte comprises (a) ball milling Na2CO3, SiO2, NH4H2PO4, a zirconium source, and a dopant to produce a ball milled powder; (b) calcining the ball milled powder to produce a calcined powder; and (c) sintering the calcined powder to produce a solid electrolyte. The zirconium source for the solid electrolyte may be ZrO2. The dopant for the solid electrolyte may be AI2O3, Fe2O3, Sb2O3, Yb2O3, or Dy2O3.

  • Patent number: 9459257
    Abstract: The present invention relates to a high-speed screening apparatus for a Raman analysis-based high-speed multiple drug. The screening apparatus according to the present invention may easily detect a Raman signal using a core-cap-shell nanoparticle which amplifies the Raman signal by 1012 times and has high reproducibility through Raman spectroscopy in which materials do not interfere with each other and a spectrum has a sharp peak to detect the Raman signal multiple times. Also, since a CCD camera, not a scanner, may be used as the detector, the screening apparatus may multiply screen the drug at a high speed without movement between molecules within a sample. In addition, since multicolors of 5 colors or more may be coated, the screening apparatus may be usefully used for screening various drugs.

  • Patent number: 9343746
    Abstract: Embodiments of the invention are directed to SOFC with a multilayer structure comprising a porous ceramic cathode, optionally a cathodic triple phase boundary layer, a bilayer electrolyte comprising a cerium oxide comprising layer and a bismuth oxide comprising layer, an anion functional layer, and a porous ceramic anode with electrical interconnects, wherein the SOFC displays a very high power density at temperatures below 700° C. with hydrogen or hydrocarbon fuels. The low temperature conversion of chemical energy to electrical energy allows the fabrication of the fuel cells using stainless steel or other metal alloys rather than ceramic conductive oxides as the interconnects.

  • Patent number: 8741791
    Abstract: A crystallized glass with negative coefficient of thermal expansion includes 38 wt % to 64 wt % of silica (SiO2); 30 wt % to 40 wt % of alumina (Al2O3); and 5 wt % to 12 wt % of lithium oxide (Li2O) as a basic component, and further includes more than one component selected from the group consisting of 0.5 wt % to 15 wt % of zirconia (ZrO2), 0.5 wt % to 6.5 wt % of titanium dioxide (TiO2), 0.5 wt % to 4 wt % of phosphorus pentoxide (P2O5), 2 wt % to 5 wt % of magnesium oxide (MgO), and 0 wt % to 5 wt % of magnesium fluoride (MgF2) in addition to the basic components. The crystallized glass may have a high negative coefficient of thermal expansion so that it has an advantage that it can be used as a thermal expansion compensation material according to the temperatures of all kinds of glasses and similar products thereof.
