The electrical signal generated is a function of the hydrogen concentration on the measuring side. | 02-16-2012 |
20130095596 | METHOD FOR TEXTURING SILICON SURFACE TO CREATE BLACK SILICON FOR PHOTOVOLTAIC APPLICATIONS - The surface of silicon is textured to create black silicon on a nano-micro scale by electrochemical reduction of a silica layer on silicon in molten salts. The silica layer can be a coating, or a layer caused by the oxidation of the silicon. | 04-18-2013 |
20130264218 | OXYGEN CONCENTRATION AND METHOD - An oxygen concentrator is for generating a flow of oxygen by electrolysis of atmospheric humidity. It comprises a cathode ( | 10-10-2013 |
20140209477 | ELECTRO-DEOXIDATION METHOD, APPARATUS AND PRODUCT - The subject invention concerns an electro-decomposition process wherein a cathode comprising a metal compound is contacted with a fused salt electrolyte in an electrochemical cell. The metal compound is a compound between a metal and another substance, and a voltage is applied between the cathode and an anode such that the substance is removed from the metal compound. In the improved method, the applied voltage increases with time, either continuously or stepwise, up to a predetermined maximum voltage. In addition, or in the alternative, the fused salt composition is selected so as to maintain a predetermined concentration of the substance in the fused salt during electro-decomposition. | 07-31-2014 |
20150056513 | POWDER COMPRISING CARBON NANOSTRUCTURES AND ITS METHOD OF PRODUCTION - A powder comprises a plurality of carbon nanostructures, with at least a portion of the carbon nanostructures defining an internal cavity that contains metallic lithium, a lithium compound, or a lithium alloy comprising lithium. A method of forming the powder involves the electrolytic disintegration of a graphite electrode in a lithium-bearing molten salt to form the carbon nanostructures, and a step of removing salt from the nanoparticles without removing lithium. A lithium battery anode comprising an anode comprising the powder as a layer on an electrically conductive substrate. | 02-26-2015 |
