摘要： In one embodiment, a membrane of proton-electron conducting ceramics that is useful for the conversion of a hydrocarbon and steam to hydrogen has a porous support of M′-Sr1-z′M″z′Ce1-x′-y′Zrx′M′″y′O3-δ, Al2O3, mullite, ZrO2, CeO2 or any mixtures thereof where: M′ is Ni, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Nb, Mo, W, Zn, Pt, Ru, Rh, Pd, alloys thereof or mixtures thereof; M″ is Ba, Ca, Mg, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, or Yb; M′″ is Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Nb, Mo, W, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, or Yb; z′ is 0 to about 0.5; x′ is 0 to about 0.5; y′ is 0 to about 0.5; and x′+y′>0; for example, Ni—SrCe1-x′Zrx′O3-δ, where x′ is about 0.1 to about 0.3. The porous support is coated with a film of a Perovskite-type oxide of the formula SrCe1-x-yZrxMyO3-δ where M is at least one of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Nb, Mo, W, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb, x is 0 to about 0.15 and y is about 0.1 to about 0.3. By including the Zr and M in the oxide in place of Ce, the stability can be improved while maintaining sufficient hydrogen flux for efficient generation of hydrogen. In this manner, the conversion can be carried out by performing steam methane reforming (SMR) and/or water-gas shift reactions (WGS) at high temperature, where the conversion of CO to CO2 and H2 is driven by the removal of H2 to give high conversions. Methods of preparing the membrane cells and a system for use of the membrane cells to prepare hydrogen are presented. A method for sequestering CO2 by reaction with methane or other hydrocarbon catalyzed by the novel membrane to form a syngas is also presented.

摘要： A flat panel display is disclosed. In one embodiment, display normal light that is parallel to a display normal of the flat panel is provided. Spaced light redirecting prisms receive the display normal light and redirect the display normal light to redirected light, which is non-parallel to the display normal. A flat surface portion is posteriorly coupled to the plurality of spaced light redirecting prisms such that the flat surface portion spans the spaces between the plurality of spaced light redirecting prisms. The flat surface portion receives the display normal light from the light guide and receives the redirected light from the plurality of spaced light redirecting prisms and propagates both to a display.

摘要： We disclose a flat panel display suitable for viewing primarily from viewing angles or envelopes that are away from the direction that is perpendicular to the display panel (display normal). We disclose a way of increase the brightness of the display at large viewing angles. It is desirable to have such a display when the display is primarily viewed from directions that are not along the display normal, such as in the case of the cockpit of a transport aircraft where a display could be viewed mostly from left and right by the pilot and co-pilot. The display uses a light re-distributor (LRD) to increase the brightness of the display at larger viewing angles. The LRD consists of light re-directing portion, light straight-transmission portion and light scattering portion. For transmissive or transflective displays, light rays from the backlight entering the LRD at the light-redirecting portions are redirected and the rays that hits the light straight-transmission portion pass the LRD without changing direction. The surface profile of the light-redirecting portion determined the viewing angles/envelopes at which the light is directed to. This surface profile and the ratio of the light-redirecting portion to the light straight-transmission portion determine how much light is redirected to the viewing angles. The light distribution can be further modified by introducing a diffuser, either by surface treatment or by laminating a diffuser film onto the LRD. The diffuser can be used to smooth out brightness sharp changes at the boundaries of primary and secondary viewing envelopes. Commercially available materials, light-redirecting films and diffuser films can be used to construct a LRD of desired light re-distributing properties, making the LRD a cost effective element of the display. The LRD can be used for displays other than LCD, such as light emitting displays where no backlight exists, by placing the LRD on top the front substrate of the display.

摘要： A liquid crystalline light modulating pixel includes first and second cell wall structures and nematic liquid crystal within a UV cured polymer network disposed therebetween. The first and second cell wall structures cooperate with the liquid crystal to form four liquid crystal domains within the pixel. The liquid crystal in each of the domains exhibits a twisted nematic liquid crystal structure and the orientation of the liquid crystal director of the liquid crystal adjacent one of the cell wall structures in at least two domains is different. The polymer network stabilizes the four domain structure at both high field and zero field conditions.
