Organic light-emitting diodes are a major driving force of the current information display revolution due to their low power consumption and potentially long operational lifetime. Although electrophosphorescent organic emitters have significantly lower power consumption than fluorescent emitters, the short lifetime of electrophosphorescent blue devices has prevented their application in display...

In the crystal of the title compound, C(8)H(9)NO(2)S, synthesized by the oxidation of 2-(methyl-sulfan-yl)benzamide using NaOCl with 2,2,6,6-tetra-methyl-piperidyl-1-oxy (TEMPO) as the catalyst, mol-ecules are linked via inter-molecular N-H⋯O(amide) hydrogen bonds, forming centrosymmetric amide-amide dimers which are extended into a two-dimensional lamellar framework parallel to (100) through a...

Recently, considerable progress has been made in designing biomaterial surfaces which possess enhanced albumin affinity. Two derivatization methods for producing albumin binding biomaterial surfaces, based on an albumin affinity dye, cibacron blue, have been developed. Both surface derivatization methods were found to enhance the binding of albumin to an implant grade polyetherurethane. Evaluat...

Most patents covering dermatologic products contain patent claims directed to the pharmaceutical formulation of the product. Such patents, known as formulation patents, are vulnerable to attacks based on the legal argument that the formulations covered are obvious over formulations already known prior to the filing of the patent application. Because obviousness is an important concept in patent...

Clinical research faces a reproducibility crisis. Many recent clinical and preclinical studies appear to be irreproducible--their results cannot be verified by outside researchers. This is problematic for not only scientific reasons but also legal ones: patents grounded in irreproducible research appear to fail their constitutional bargain of property rights in exchange for working disclosures ...

In the centrosymmetric title complex, [Ni(C(7)H(6)NO(2)S)(2)(H(2)O)(4)], the Ni(II) atom, located on a centre of inversion, is coordinated by two N atoms from two 2-(4-pyridyl-sulfan-yl)acetate ligands and four water O atoms in an octa-hedral geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the carboxyl-ate group of the anionic 2-(4-pyr...

Are boundaries between color categories associated with enhanced discrimination? In the present experiments, chromatic thresholds were obtained for discriminations along lines orthogonal to the yellow-blue axis of color space. The targets were parafoveal and thresholds were measured with a spatial two-alternative forced choice. In interleaved experimental runs, we also obtained empirical estima...

Blue gourami fish have a pair of modified ventral fins that are used to obtain tactile information about surrounding objects. Use of ventral fins by blue gourami was investigated during initial exploration of novel objects. When exposed to a sequence of novel plastic objects, varying in shape and colour, the blue gourami showed preferential use of the left fin during initial contacts. Lateralit...
