    Abstract: Described herein is a gas detection system (5) including a housing (10) having an inlet (20) in fluid communication with an atmosphere; an analyzer (25) within the housing (20) and configured to detect and measure a gas species in the atmosphere using a gas sensor (37); and a pneumatic system (60) contained within the housing (10) and in fluid communication with the inlet (20) to draw an air sample from the atmosphere. The pneumatic system (60) includes a pump (15); a low flow branch (65) in fluid communication with the pump (15) and having an airflow sensor (90) and a first orifice (85); and a high flow branch (70) in fluid communication with the pump (15) and having a second orifice (95).

    Abstract: The catalytic composition for the electrochemical reduction of carbon dioxide is a metal oxide supported by multi-walled carbon nanotubes. The metal oxide may be nickel oxide (NiO) or tin dioxide (SnO2). The metal oxides form 20 wt % of the catalyst. In order to make the catalysts, a metal oxide precursor is first dissolved in deionized water to form a metal oxide precursor solution. The metal oxide precursor solution is then sonicated and the solution is impregnated in a support material composed of multi-walled carbon nanotubes to form a slurry. The slurry is then sonicated to form a homogeneous solid solution. Solids are removed from the homogeneous solid solution and dried in an oven for about 24 hours at a temperature of about 110° C. Drying is then followed by calcination in a tubular furnace under an argon atmosphere for about three hours at a temperature of 450° C.

  • Patent number: 8741113
    Abstract: The present invention concerns an electrochemical pattern replication method, ECPR, and a construction of a conductive electrode for production of applications involving micro and nano structures. An etching or plating pattern, which is defined by a conductive electrode, a master electrode, is replicated on an electrically conductive material, a substrate. The master electrode is put in close contact with the substrate and the etching/plating pattern is directly transferred onto the substrate by using a contact etching/plating process. The contact etching/plating process is performed in local etching/plating cells, that are formed in closed or open cavities between the master electrode and the substrate.

    Abstract: An efficient and low environmental impact method is disclosed for the recovery of lithium from aqueous solution, for example, brines from high altitude salt lakes. The method comprises the use of an electrochemical reactor with electrodes which are highly selective for lithium, where lithium ions are inserted in the crystal structure of manganese oxide in the cathode, and extracted from the crystal structure of manganese oxide in the anode. Also disclosed are three-dimensional carbon electrodes embedded in manganese oxides formed by impregnating a porous support, for example a carbon felt, with a manganese oxide/carbon black slurry.

  • Publication number: 20140054178
    Abstract: An electrode mask for electrowinning a metal is provided. An example technique forms openings in a solid nonconductive sheet, such as vinyl, polyvinyl chloride (PVC), or other plastic and adheres the sheet as a solid to a cathode surface as a mask. The mask protects the cathode surface from electrical interaction with an electrolyte, while the openings allow controlled electrodeposition of a metal in harvestable rounds, which can be stripped from the cathode. The electrode mask is reusable, and easily removed for recycling and replacement. A matrix design engine calculates pattern and sizes for the openings in the mask to optimize electrodeposition of the metal based on multiple parameters including the metal to be deposited, ions present in an electrolyte, electrolyte concentration, pH level, voltage, electrical current density, solution temperature, electrode temperature, or plating time.
