The do bias field. dependence of the dielectric loss in SrTi03 thin films deposited onto MgO substrate is investigated. The experimental data obtained at different frequencies of the ac field (8 and 16 GHz) from differently processed films (as deposited an ...
Permanence issues for digital photographs arise in three different areas. First, the materials used for digital hard copies should preferably be as permanent as the conventional photographic materials. Longevity of digital hard copy materials is affected b ...
Selective modification of zirconium alkoxide by acetic acid or acetylacetone was used in solution processing of PZT Pb(Zr,Ti)O-3 thin films by 2-methoxyethanol route. EXAFS results clearly show a decrease of Zr-O-Zr links in the acetic acid modified PZT so ...
A photog. material with improved physicomech. properties and photog. characteristics contains a combination of gelatin and a water-sol. polymer in the form of a symplex. Thus, a cellulose acetate support was coated with a coupler-contg. Ag(Br,Cl,I) (15 mol ...
This comprehensive treatise, featuring the history and historical processes of photography, contemporary applications, and the new and evolving digital technologies, will provide the most accurate technical synopsis of the current, as well as early worlds ...
A novel strategy for imaging commercial black-and-white negative photo films by scanning electrochemical microscopy (SECM) is demonstrated. The imaging is based on using IrCl3 6 as the redox mediator to dissolve silver grains. The SECM probe is biased at a ...
Photog. materials having improved antistatic characteristics contain in an antihalation layer, interlayer, or top layer a homo- or copolymer having repeating units with a quaternary ammonium structure of the formula I (R-R3 = H or C1-6 alkyl; R4,R5 = C1-18 ...
In this paper, we present near-field optical images of nanostructures exhibiting an extraordinary transmission. These structures consist of annular aperture arrays engraved in a metallic film: they are quite promising structures for nanophotonics because o ...
Almost all conventional acid filter dyes can be rendered nondiffusing in emulsion or thin auxiliary layers, without lowering their phys.-mech. properties or interference with their bleachability or washing-out during processing by a small amt. of a mordant ...
