Abstract:
Methods and apparatus are provided for the preparation of a substrate having an array of diverse materials, the materials being deposited at spatially addressable, predefined regions. In particular, potential masking systems are provided which generate spatially and temporally varying electric, magnetic and chemical potentials across a substrate. These varying potentials are used to deposit components of source materials onto a substrate in a combinatorial fashion, thus creating arrays of materials that differ slightly in chemical composition, concentration, stoichiometry, and/or thickness. The diverse materials may be organized in discrete arrays, or they may vary continuously over the surface of the substrate. The shape of the potential allows the determination of the composition of the resulting materials at all locations on the substrate.
Abstract:
The invention provides methods, apparatus, and systems for performing high-throughput preparation and screening of salts and polymporphs of drug candidates. The invention is directed towards enhancing the pre-formulation discovery process used for drug development. In particular, processes that determine suitable salts and processes that discover substantially every polymorph that can form from a particular drug candidate are provided. The processes are performed using several apparatuses that are specifically configured to carry-out various steps in a high-throughput characterization process. One such apparatus is configured for synthesizing a plurality of library members based on, for example, a library model generated by a computer system.
Abstract:
Methods and apparatus for screening diverse arrays of materials (1205) are provided. In particular, techniques for rapidly characterizing compounds in arrays of materials (1205) in order to discover and/or optimize new materials with specific desired properties are provided. The substrate (403) can be screened for materials having useful properties, and/or the resulting materials can be ranked, or otherwise compared, for relative performance with respect to useful properties or other characterizations. In particular, systems (1200, 1300, 1400) and methods are provided for screening a library of magnetic materials (1205) for their bulk magnetization, saturation magnetization, and coercivity by imaging their individual optical Kerr rotation, screening a library of dielectric materials (1205) for their dielectric coefficients by imaging their individual electro-optical rotation and screening a library of luminescent materials by imaging their individual luminescent properties under a variety of excitation conditions. Optical or visible luminescence systems (1200, 1300, 1400) are also provided as well as their application to screening libraries of different materials (1205).

Abstract:
A device for the generation of specific colored light including white light by luminescent down conversion and additive color mixing based on a light-emitting diode 'LED'(1) comprising a semiconductor light-emitting layer emitting near UV light about 370-420 nm or blue light about 420-480 nm and phosphors (6) which absorb completely or partly the light emitted by the light-emitting component and emit light of wavelengths longer than that of the absorbed primary light, wherein the light emitting layer of the light emitting component is preferably a Ga(In)N-based semiconductor; and at least one of the phosphors (6) contains a metal sulfide fluorescent material activated with europium containing at least one element selected from the group consisting of Ba, Sr, Ca, Mg and Zn; and/or at least another phosphor (6) which contains a complex thiometalate fluorescent material activated with either europium, cerium or both europium and cerium containing at least one element selected from the group consisting of Ba, Sr, Ca, Mg and Zn; and at least one element selected from the group consisting of Al, Ga, In, Y, La and Gd.
