    摘要: A process for making cerium dioxide nanoparticles containing at least one transition metal (M) utilizes a suspension of cerium hydroxide nanoparticles prepared by mechanical shearing of an aqueous mixture containing an oxidant in an amount effective to enable oxidation of cerous ion to ceric ion, thereby forming a product stream that contains transition metal-containing cerium dioxide nanoparticles, Ce1-xMxO2, wherein “x” has a value from about 0.3 to about 0.8. The nanoparticles thus obtained have a cubic fluorite structure, a mean hydrodynamic diameter in the range of about 1 nm to about 10 nm, and a geometric diameter of less than about 4 nm. The transition metal-containing crystalline cerium dioxide nanoparticles can be used to prepare a dispersion of the particles in a nonpolar medium.

    摘要: A photographic emulsion is disclosed comprised of a dispersing medium and radiation-sensitive silver halide grains with greater than 50 percent of total grain projected area being accounted for by grains containing a host portion of a face centered cubic rock salt crystal lattice structure and a first epitaxial phase containing greater than 90 mole percent iodide. The host portion is tabular, being bounded by an exterior having first and second parallel major faces joined by a peripheral edge. The first epitaxial phase accounts for less than 60 percent of total silver, and the first epitaxial phase is restricted to a portion of the exterior of the host portion that includes at least 15 percent of the major faces.

    摘要: A dry release transfer is disclosed in which the design layer is formed by printing one or more inks onto a carrier sheet, at least one of the inks being a photopolymerizable composition, and subjecting the design layer to ultra-violet radiation or an electron beam discharge in order to polymerize the photopolymerizable ink. By suitable selection of polymerizable components of the ink so that the photopolymerized ink has a high Young's modulus, a stress-resisting design layer is produced which will release readily from the carrier on mechanically stressing the carrier, e.g. by rubbing lightly with a ball-point pen.
