    摘要： An improved electrochemical cell comprising an additive-modified molten alkali metal electrode-reactant and/or electrolyte is disclosed. Various electrochemical cells employing a molten alkali metal, e.g., sodium, electrode in contact with a cationically conductive ceramic membrane experience a lower resistance and a lower temperature coefficient of resistance whenever small amounts of selenium are present at the interface of the electrolyte and the molten alkali metal. Further, cells having small amounts of selenium present at the electrolyte-molten metal interface exhibit less degradation of the electrolyte under long term cycling conditions.

    摘要： An energy conversion device comprising an improved sealing member adapted to seal a cation-permeable casing to the remainder of the device. The sealing member comprises a metal substrate which (i) bears a nonconductive and corrosion resistant coating on the major surface to which said casing is sealed, and (ii) is corrugated so as to render it flexible, thereby allowing said member to move relative to said casing without cracking the seal therebetween. Corrugations may be circumferential, radial, or both radial and circumferential so as to form dimples. The corrugated member may be in form of a bellows or in a substantially flat form, such as a disc.

    摘要： A core-shell catalyst material can include a core and a shell material. Each of the core material and the shell material can have crystal structures and lattice parameters which allow for a substantially coherent core-shell interface. The shell material can include a catalytically active metal. The circumferential stress of the shell material, σθθ, at the core-shell interface and at the shell surface, is greater than 0 (tensile) or can be compressive of a lower magnitude than a catalyst made of the shell material alone. The crystal structures of the core material can often be the same as the shell material, although this is not always required.

    摘要： Structural failures, as in metal aircraft structures, are rapidly detected and measured by use of a new detection system comprising a thin film adhesively bonded to the metal structural surface to be monitored, said film containing a plurality of thin continuous strips which are adapted to be broken when a crack appears under the strips, said strips being substantially parallel but insulated from each other and the metal structural surface and arranged in a pattern such that there is frequent change in direction of the strips as in a zig-zag or rectangular pattern, each of said strips constituting a separate circuit joined to an electric power source and a sensing and recording means capable of detecting and recording any circuit failure caused by disruption of the metal strip, said disruption being caused by the formation of a crack under the said strip.

Each of the core material and the shell material can have crystal structures and lattice parameters which allow for a substantially coherent core-shell interface. The shell material can include a catalytically active metal. The circumferential stress of the shell material, Gee, at the core-shell interface and at the shell surface, is greater than 0 (tensile) or can be compressive of a lower magnitude than a catalyst made of the shell material alone. The crystal structures of the core material can often be the same as the shell material, although this is not always required.
