  • Patent number: 10444618
    Abstract: A method is used to prepare silver nanoparticles in the form of a silver nanoparticle cellulosic polymeric composite. A cellulosic polymer, organic solvent having a boiling point at atmospheric pressure of 100° C. to 500° C. and a Hansen parameter (?TPolymer) equal to or greater than that of the cellulosic polymer, and a nitrogenous base are mixed to form a premix solution. Upon heating the premix solution to a temperature of at least 75° C., a solution of reducible silver ions is added that is equimolar or less in relation to the nitrogenous base. The weight ratio of reducible silver ions to the cellulosic polymer is 5:1 to 50:1. The resulting silver nanoparticle composite is cooled, isolated, and re-dispersed in an organic solvent, providing a non-aqueous silver-containing dispersion comprising the silver nanoparticle cellulosic polymeric composite.

  • Patent number: 7790233
    Abstract: The invention relates to a process for the formation of a coating of metal oxides comprising at least one precious metal from Group VIII of the Periodic Table of the elements, optionally in combination with titanium and/or zirconium, on an electrically conductive substrate made of steel or of iron, which consists in applying a sole solution of acetylacetonate(s) of the said metal(s) dissolved in a (plurality of) solvent(s) which specifically dissolve(s) each metal acetylacetonate; and in then drying and calcining the coated substrate. The invention also relates to an activated cathode obtained from the electrically conductive substrate coated with metal oxides and to its use in the electrolysis of aqueous solutions of alkali metal chlorides.

  • Patent number: 7727322
    Abstract: A method for manufacturing a precursor solution for forming a PZTN compound oxide with Pb, Zr, Ti and Nb as constituent elements by a sol-gel method includes: a step of dissolving at least lead carboxylate with an organic solvent having an alkoxy group, to thereby form a first solution; a step of heat treating the first solution to remove crystallization water of the lead carboxylate and to form lead alkoxide by a ligand replacement reaction between the lead carboxylate and the organic solvent having the alkoxy group, to thereby form a second solution including the lead alkoxide; a step of mixing an alkoxide of a metal selected from at least one of Zr, Ti and Nb excluding Pb with the second solution, to thereby form a third solution including metal alkoxides of Pb, Zr, Ti and Nb, respectively; and a step of adding water to the third solution to cause hydrolysis-condensation of the metal alkoxides, to thereby form a fourth solution including a precursor of PZTN compound oxide.

    Abstract: A container made of a porous material and coated with precious metal nanoparticles is disclosed. The method of making it includes: adding precious metal nanoparticles and intermedium particles to a solution; maintaining the solution at a first temperature; heating a container body made of a porous material at a second temperature; and immersing the container body in the solution wherein the temperature difference between the first temperature and the second temperature causes the precious metal nanoparticles and intermedium particles to permeate into the pores of the container body. The resultant container has precious metal nanoparticles not only attached to its surface but also within its pores.
