Abstract: An electrode, in particular a gas diffusion electrode, for a metal-oxygen battery. To achieve an improved performance output, e.g., an improved energy density or an improved capacity, the electrode includes a porous carrier substrate on which a porous active material is situated, the electrode having a gradient of medium pore sizes between the carrier substrate and the active material. Also described is an energy store including the electrode as described.

Abstract: In a method for determining the state of charge of an electrical accumulator, individual cell voltages are recorded, and the highest and/or the lowest individual cell voltage is ascertained. A present maximum charge and/or a present minimum charge of the appertaining accumulator cell is determined using a characteristic curve and the highest and/or the lowest individual cell voltage.

Abstract: A burner cleaning device for cleaning burners, in particular for gas turbine burners, with a fuel nozzle and a fuel supply line is disclosed. The burner cleaning device has a rinsing head provided with an opening that is placed on a fuel nozzle of the burner and that enables a rinsing fluid to be supplied to or evacuated from the nozzle, and/or a fluid line that is connected to the fuel supply line of the burner and that enables the rinsing fluid to be supplied to or evacuated from the fuel supply line, and a pump. The pump, the rinsing head and/or the fluid line are fluidically interconnected such that they form a flow path through which the rinsing fluid sequentially flows.

Abstract: A cathode composition for an alkali-sulfur cell, e.g., a lithium-sulfur cell, includes, in addition to elementary sulfur, at least one material having covalently and/or conically bound sulfur, for example, a sulfur composite material, a sulfurous polymer, a metal sulfide, or a nonmetal sulfide.

Abstract: A sensor element for determining a gas component in a measuring gas includes a first and a second electrode, a solid electrolyte situated between the electrodes, a heater having a heating element, and an insulation surrounding the heating element, wherein the heating element has a meander pattern having a first external heating area, a second external heating area, a first internal heating area, and a second internal heating area.

Abstract: The invention relates to a method and a system for handling long objects, in particular packing extruded profiles. It comprises two robots with one arm each, said arm having a pair of grippers, and a control unit that coordinates and controls the movement of the robots. In the handling operation the mutual distance between the two said pair of grippers are held constant, to counteract misalignment of the object.

Abstract: A sensor element for determining a physical property of a test gas, e.g., the concentration of a gas component in a gas mixture, in particular the oxygen concentration in the exhaust gas from internal combustion engines, has a solid electrolyte body, an external electrode exposed to the test gas situated on the solid electrolyte body, an internal electrode situated in the solid electrolyte body, and an electrical resistance heater which has a meandering heating surface situated in the solid electrolyte body, and is embedded in insulation. The external electrode is situated in a cavity formed in the solid electrolyte body to reduce the heat losses from the sensor element due to convection and radiation to the cold test gas flow.

Abstract: The invention relates to a method for the production of a monocrystalline layer on a substrate with a non-adapted lattice. To this end, a monocrystalline substrate with a buried amply defective layer and a monocrystalline layer produce thereon are used. The buried amply defective layer can be produced by hydrogen implantation.
