Abstract:
In a manufacturing step for forming an organic EL element, the organic EL element is provided so as to have an anode and a cathode with a luminescent layer having an organic luminescent material interposed therebetween. Then, an aging treatment is performed. In the aging treatment, a curve of change in luminance with time is measured in driving the organic EL element at constant current. Then, the curve of change in luminance with time is divided into a component having a slowest luminance age-deterioration rate and other components by analyzing the curve and forming a fitting curve having a plurality of members that is fitted to the curve of change in luminance with time. Moreover, the aging treatment is conducted until a luminance of the element becomes approximately equal to an initial value A1 of the component having a slowest luminance age-deterioration rate.
Abstract:
A birefringent plate comprising a transparent substrate and an obliquely evaporated film formed on the transparent substrate, is free from the visual angle dependence because the obliquely evaporated film is formed into a multilayer composition and the neighboring layers have a different evaporation direction. Moreover, a manufacturing method for the birefringent plate, using a device constituted of a vacuum chamber and a crucible having a large number of inclined through holes, is capable of making the film thickness of the obliquely evaporated film uniform.
Abstract:
Bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.
Abstract:
An omnidirectional reflector that reflects a band of electromagnetic radiation of less than 100 nanometers when viewed from angles between 0 and 45 degrees is provided. The omnidirectional reflector includes a multilayer stack having a plurality of layers of high index of refraction material and a plurality of layers of low index of refraction material. In addition, the plurality of high index of refraction material layers and low index of refraction material layers are alternately stacked on top of or across each other and provide a non-periodic layered structure.
Abstract:
Polyaniline is added into a glycidyl group- or isocyanate group-containing (meth)acrylate to obtain a polyaniline-added prepolymer, and then the obtained polyaniline-added prepolymer and another unsaturated group-containing monomer undergo additive copolymerization at their respective double bonds to obtain a polyaniline graft polymer having a weight-average molecular weight of 1,000 to 100,000.
Abstract:
A method for producing a multi-layer photonic structure having at least one group of alternating layers of high index material and low index material may include, determining a characteristic property function for the multi-layer photonic structure, determining a thickness multiplier for the at least one group of alternating layers based on a comparison of the characteristic property function to a target profile, adjusting the characteristic property function with the determined thickness multiplier, and comparing an adjusted characteristic property function to the target profile, wherein, when the adjusted characteristic property function does not approximate the target profile, at least one additional group of layers is added to the multi-layer photonic structure.
Abstract:
Protein-polymer compositions and processes for their production are provided where the compositions have improved resistance to ultraviolet light induced weathering and associated loss of enzyme activity. The incorporation of both a sterically hindered amine and an ultraviolet light absorber at a concentration of at least 5% by weight produces a curable or cured composition with UV stabilized enzyme activity that can be used as a bioactive coating with improved stain removal properties.
