Abstract: HIGH EDGE CUBICITY TUBULAR GRAIN EMULSIONS Tabular grain silver bromide and silver bromoiodide emulsions are disclosed in which less than 75 percent of the edge surfaces joining the opposed parallel major octahedral grain faces of the tabular grains lie in {111} crystallographic planes. By increasing the edge cubicity (the proportion of the edge surfaces lying in non-{111} crystallographic planes) of the tabular grains the photographic properties of the emulsion are improved. The grains are in one form doped with iron and cyano ligands.

Abstract: PHOTOGRAPHIC ELEMENTS WITH IMPROVED ACCUTANCE A photographic element is disclosed comprised of a support, a first silver halide emulsion layer responsive to minus blue (500 to 700 nm) light and a second silver halide emulsion layer positioned to overlie the first emulsion layer. In the second emulsion layer greater than 97 percent of the total projected area of grains having an equivalent circular diameter of at least 0.2 .mu.m is accounted for by silver bromoiodide tabular grains having an average equivalent circular diameter of at least 0.7 .mu.m and an average thickness of less than 0.07 .mu.m.

Abstract: HIGHLY UNIFORM SILVER BROMOIODIDE TABULAR GRAIN EMULSIONS AND PROCESSES FOR THEIR PREPARATION Novel tabular grain emulsions and a process for their preparation are disclosed in which silver bromoiodide tabular grains account for greater than 97 percent of total grain projected area and the coefficient of variation of the total grain population is less than 25 percent. This is achieved by forming in a first reaction vessel and transporting to a second reaction vessel a population of silver bromide grain nuclei in the form of regular octahedra having an equivalent circular diameter of less than 40 nanometers and a coefficient of variation of less than 50 percent and in the second reaction vessel converting the grain nuclei into a grain population containing parallel twin planes in more than 90 percent of the grains, so that upon further growth silver bromoiodide tabular grains of desired properties can be realized.

Abstract: Authentication systems, apparatus, and methods authenticate an identification marking including a nanocrystalline material. One or more properties of the marking are ascertained to provide a measured profile. The measured profile is compared to at least one member of a closed set of reference profiles. Each reference profile has predetermined values of one or more properties. Each reference profile is unique within the set. At least one reference profile is characteristic of an indicator material in a nanocrystalline morphology and non-characteristic of the same indicator material in a bulk morphology.
