  • Patent number: 9261787
    Abstract: Black-and-white silver halide conductive film element precursors have, on one or both sides and in order, a UV filter layer, non-color hydrophilic photosensitive layer comprising a silver halide, and a hydrophilic overcoat as an outer layer. The one or two UV filter layers individually contains one or more UV absorbing agents in an amount of up 0.5 mmol/m2 and the total amount in the precursor is up to 1 mmol/m2 to prevent crosstalk during imagewise exposure. These precursors can be imagewise exposed and processed to provide conductive film elements with various conductive silver patterns (or grids) with narrow conductive silver lines on one or both sides. Such conductive film elements can be prepared with reduced yellowness as evidenced by reduced b* values. The resulting conductive film elements are highly transparent and can be used in various devices such as display devices.

  • Patent number: 9171982
    Abstract: Provided are novel building integrable photovoltaic (BIPV) modules having integrated jumpers for interconnecting similar modules in adjacent rows. An integrated jumper is provided on a back side of the photovoltaic portion of the module and includes at least two interconnected jumper contact points. The module also has two connectors provided on the front side of its flap portion. Each connector has at least one connector contact point connected to one or more photovoltaic cells of the module. When a module is positioned over flap portions of two other modules previously installed in an adjacent row, the two jumper contact points on the back side of this new module make electrical connections to the two connector contact points on the front side of the installed modules. In turn, these connections interconnect the photovoltaic cells of the two modules without any need for additional connectors or operations.

  • Patent number: 7354733
    Abstract: We disclose methods of sorting or separating mixtures of living cells (e.g., eukaryotic, prokaryotic, mammalian, pathogenic, bacterial, viral, etc.). We perform our methods by activating cell-selective photophoric labels, which photosensitize and chemically reduce a photosensitive metal compound to form metal grains, particles or crystals. The metal adheres to the cells and forms the basis for sorting or separating different cell types. Photophoric labels may include chemiluminescent agents such as peroxidase enzymes activated with peroxidase substrates capable of luminescence. Photosensitive metal compounds may be present in a light-sensitive matrix or emulsion containing photosensitizable metal compounds, which form metal grains, particles or crystals upon exposure to a developer solution. Developer solutions are formulated to substantially allow living cells to remain viable after exposure to the developing solution.

  • Patent number: 6713226
    Abstract: The present invention relates to an ultrahigh contrast photographic material comprising a support bearing a silver halide emulsion layer, containing at least one hydrazide nucleating agent in the emulsion layer and/or a hydrophilic colloid layer, wherein the nucleating agent comprises 2 to 4 hydrazide moieties which are linked directly to one another or to one another by a linking group. The material optionally contains a booster compound in the emulsion layer or hydrophilic colloid layer to enhance the ultrahigh contrast and to promote activity, or a booster compound may be present in the developer solution. The nucleating agents show unexpectedly good nucleation and low sensitivity to variation in development conditions and their synthesis is consistent, efficient and robust.
