    摘要: A planar, rigid substrate made from a porous, inorganic material coated with cationic polymer molecules for attachment of an array of biomolecules, such as DNA, RNA, oligonucleotides, peptides, and proteins. The substrate has a top surface with about at least 200 to about 200,000 times greater surface area than that of a comparable, non-porous substrate. The cationic polymer molecules are anchored on the top surface and in the pores of the porous material. In high-density applications, an array of polynucleotides of a known, predetermined sequence is attached to this cationic polymer layer, such that each of the polynucleotide is attached to a different localized area on the top surface. The top surface has a surface area for attaching biomolecules of approximately 387,500 cm2/cm2 of area (˜7.5 million cm2/1×3 inch piece of substrate). Each pore of the plurality of pores in the top surface of the substrate has a pore radius of between about 40 Å to about 75 Å. Not only does the cationic coating in and over the pores of the substrate greatly increase the overall positive charge on the substrate surface, but also given the size of the pores provides binding sites to which biomolecules can better attach.

    摘要: An improved electrode design for solid state devices, fuel cells, sensors and the like is made by incorporation of a porous layer of the electrolyte material over the dense electrolyte, and by the introduction of an electrocatalyst into the porous layer such that it is also continuous. The resulting electrode structure of dense electrolyte/porous electrolyte, continuous electrocatalyst and gas phase are present creating an enhanced three phase (TPB) length over that of conventional designs. The design allows for improved performance at lower temperatures which means a lower cost of materials, fewer problems from oxidation and corrosion, and improved durability. In a preferred embodiment, the dense electrolyte and porous electrolyte is yttria-stabilized zirconia (YSZ), and the electrocatalyst is selected from silver; platinum; rhodium; palladium; iridium; ruthenium;(La.sub.1-x Sr.sub.x) MnO.sub.3, wherein x is 0 to 0.5;(La.sub.1-x Sr.sub.x) CoO.sub.3, wherein x is 0 to 0.6;(La.sub.1-x Sr.sub.x)(Co.sub.1-y Fe.sub.y)O.sub.3, wherein x is 0 to 0.4 and y is 0 to 0.8;In.sub.2 O.sub.3 --PrO.sub.1.83 --ZrO.sub.2, having composition ratios of In.sub.2 O.sub.3 of 0-90%, PrO.sub.1.83 of 10-60% and ZrO.sub.2 of 0 to 50%;TbO.sub.2 being 35 to 40% doped with YSZ;SnO.sub.2 being 0 to 20% doped with In.sub.2 O.sub.3 ;ZrO.sub.2 being 0 to 40% doped with In.sub.2 O.sub.3 ;Sm.sub.0.5 Sr.sub.0.5 CoO.sub.3 ;La.sub.0.6 Ca0.4MnO.sub.3 ;Y.sub.1-x Ca.sub.x FeO.sub.3, wherein x is 0 to 1;SrCo.sub.1-x Fe.sub.x O.sub.3, wherein x is 0.2 to 0.8;TiO.sub.2 being 0-30% doped with YSZ; or mixtures thereof.

    摘要: An electrolytic perovskite and method for synthesizing the electrolytic perovskite are described herein. Basically, the electrolytic perovskite is a solid that has an ion conductivity greater than 10−5 S/cm in a temperature range of 0–400° C., wherein the ion is Li+, H+, Cu+, Ag+, Na+ or Mg2+. For example, Li1/8Na3/8La1/4Zr1/4Nb3/4O3 (5.26×10−4 S/cm) and Li1/8K1/2La1/8NbO3 (2.86×10−3 S/cm) are two electrolytic perovskites that have been synthesized in accordance with the present invention that have a high Li+ conductivity at 20° C. Both compositions have been confirmed in experiments to conduct Ag+ and H+ ions, as well. The present invention also includes a solid proton conductor that can be formed from the electrolytic perovskite by replacing the ions located therein with protons. The electrolytic perovskite and solid proton conductor can be used in a wide variety of applications or devices including, for example, a fuel cell, a membrane reactor, an amperometric hydrocarbon sensor or a steam electrolysis application.
