Abstract:
A method for calculating an offset value for aligned deposition of a second pattern onto a first pattern, comprising steps of: (a) loading a substrate with the first pattern on a surface of the substrate into a pattern recognition device at an original position inside the pattern recognition device; (b) determining a coordinate of a prescribed point of the first pattern by the pattern recognition device; (c) superimposing the second pattern onto the first pattern on the surface of the substrate; (d) bringing back the substrate with the first pattern and the second pattern into the original position inside the pattern recognition device; (e) determining a coordinate of a prescribed point of the second pattern by the pattern recognition device; wherein the prescribed point of the first pattern corresponds to the prescribed point of the second pattern; and (f) calculating the offset value between the first pattern and the second pattern.
Abstract:
The present invention relates to novel endogenous variants of erythropoietin (EPO) and their use for treatment or prevention of a condition associated with tissue damage due to cell death (apoptosis, necrosis) and inflammation, in particular for neuroprotection, e.g. treatment of acute (for example stroke) and chronic disease (for example ALS) of the nervous system.
Abstract:
Matrixes doped with semiconductor nanocrystals are provided. In certain embodiments, the semiconductor nanocrystals have a size and composition such that they absorb or emit light at particular wavelengths. The nanocrystals can comprise ligands that allow for mixing with various matrix materials, including polymers, such that a minimal portion of light is scattered by the matrixes. The matrixes of the present invention can also be utilized in refractive index matching applications. In other embodiments, semiconductor nanocrystals are embedded within matrixes to form a nanocrystal density gradient, thereby creating an effective refractive index gradient. The matrixes of the present invention can also be used as filters and antireflective coatings on optical devices and as down-converting layers. Processes for producing matrixes comprising semiconductor nanocrystals are also provided. Nanostructures having high quantum efficiency, small size, and/or a narrow size distribution are also described, as are methods of producing indium phosphide nanostructures and core-shell nanostructures with Group II-VI shells.

Abstract:
Ligand compositions for use in preparing discrete coated nanostructures are provided, as well as the coated nanostructures themselves and devices incorporating same. Methods for post-deposition shell formation on a nanostructure and for reversibly modifying nanostructures are also provided. The ligands and coated nanostructures of the present invention are particularly useful for close packed nanostructure compositions, which can have improved quantum confinement and/or reduced cross-talk between nanostructures.
