Abstract: Disclosed are solid oxide fuel cell systems, and methods for reducing temperature distribution across electrolytes within solid oxide fuel cells (SOFC), and increasing overall system efficiency. In one embodiment, the SOFCs include preheating channels that are interposed between electrolyte electrode assemblies within SOFCs, to provide internal heat exchange. The fuel and/or air entering the SOFC can be preheated in the preheating channels, thereby reducing or eliminating the need for an external preheating system. The preheating channels also provide barriers between each electrolyte electrode assembly, which aids in isolating damage within a single fuel cell.

Abstract: An optical transducer includes an optical element for directing an electromagnetic wave to a focal region and a metallic nano-structure having a longitudinal axis non-parallel to an electric field of the electromagnetic wave. The optical element for directing an electromagnetic wave may comprise one of a solid immersion lens, a solid immersion mirror, or a planar waveguide. The metallic nano-structure may comprise a metallic pin. The metallic nano-structure may be structured and arranged for resonant coupling of energy into a recording medium.

Abstract: Systems, methods, apparatus and products relate to display glass from curved glass ribbons, to improve shape stability in glass ribbons, to creation of reduced stress glass ribbons, and to creation of improved shape stability and reduced stress of display glass, which may include forming slightly a curved glass ribbon in a fusion draw machine (FDM). One or more embodiments may include an isopipe having a desired curvature; an isopipe having a desired incline; an offset draw device operable to draw the glass ribbon in an inclined ribbon draw direction; one or more air jets or vacuum operable to apply air pressure to a first side of the glass ribbon, thereby creating a pressure differential on the first side; and/or one or more electrostatic force generators operable to apply electrostatic force to a first side of the glass ribbon, thereby generating an electric field differential across the glass ribbon.
