摘要:
A photographic element comprises a support having thereon a layer containing a copolymer comprising a vinylimidazole in association with metal ions. The metal forms a novel complex with the polymer and photographic elements comprising these materials are useful in diffusion transfer processes, and particularly useful with metal-coordinating dyes such as chelating dyes or dye-forming materials to provide a metallized dye image.
摘要:
A fuel bundle surrogate for the irradiation of a target material, having a plurality of tube sheaths, each tube sheath being parallel to a longitudinal center axis of the fuel bundle surrogate, a plurality of end caps, a pair of end plates, wherein the end plates are disposed at opposing ends of the plurality of tube sheaths, and a first target comprised of a first target material suitable for producing the isotope by way of a neutron capture event, wherein the first target is disposed in a first tube sheath, and wherein the first tube sheath of the plurality of tube sheaths comprises an elongated thickened wall portion and a pair of annular end portions, each annular end portion being disposed on a corresponding end of the thickened wall portion and having a wall thickness that is less than a wall thickness of the thickened wall portion.
