The Photo Products Department of E. I. du Pont de Nemours has recently made available a new type of polyester film, Cronar, for use in the electrophoretic separation of plasma lipoproteins. This film does not take up lipid dyes. There is no background color. The film remains clear and transparent after staining for lipoproteins.

In 2010, FUJIFILM introduced “ETERNA-RDS” that is a black and white film used for archiving from color digital masters. ETERNA-RDS is the first film stock in the world designed especially for a digital separation workflow using a film recorder. ETERNA-RDS offers a significant improvement over conventional non-specific separation film stock, accurate gradation linearity, improved granularity, su...

Successful application of sol-gel, metalorganic decomposition, or hydrothermal routes to ceramic thin films depends on the mechanical integrity of the precursor film. Above a critical thickness, a precursor film will crack or decohere from the substrate during drying. The cracking and thickness of thin metalorganic precursor films were simultaneously observed during drying using a standard opti...

A new pH-sensing film was developed by using tamarind seed polysaccharide (TSP) and natural dye extracted from litmus lichen (LLE). The addition of LLE from 0 to 2.5% decreased the tensile strength and elongation at break from 30.20 to 29.97 MPa and 69.73% to 60.13%, respectively, but increased the water vapor permeability from 0.399 × 10−9 to 0.434 × 10−9 g·s−1·m−1·Pa−1. The UV–Vis spectra of ...

A photonic shape memory polymer film that shows large color response (∼155 nm) in a wide temperature range has been fabricated from a semi-interpenetrating network of a cholesteric polymer and poly(benzyl acrylate). The large color response is achieved by mechanical embossing of the photonic film above its broad glass transition temperature. The embossed film, as it recovers to its original sha...

An inline spectrometer has been developed to monitor shot-by-shot pulse energies of a two-color X-ray beam. A thin film of diamond allows inline operation with minimum absorption. The absolute pulse energy for each color is determined by the inline spectrometer combined with a total pulse-energy monitor. A negative correlation is found between the two-color pulse energies.

new edible composite films formed from salep (orchis mascula) and 10%, 20%, and 30% (w/w) oleic acid were prepared by emulsification with the aim of improving the water vapor barrier and mechanical properties of the film. as oleic acid concentration increased up to 30% (w/w), oxygen permeability (27%), elongation at break (86%) and thickness (2%) of salep films increased significantly and the t...

The directional arrangement of the illumination plays an important role on image contrast and sharpness of silver-based photographic film. This paper explores how the directional arrangement of light (directed or diffuse) affects cinematographic colors. The experimental results show that a consistent color difference can be observed between the image projected on screen (directed illumination) ...

When typesetting a color book the goal is to produce a separate printer plate for each of the colors. The process of splitting the printed output into separate plates is called color separation. There are two color separation methods commonly used. Custom color separation selects colors from a standard pallet. A different plate is created for each color in the book. Process color separation sep...
