Abstract: Ligands, compositions, and metal-ligand complexes that incorporate heterocycle-amine compounds are disclosed that are useful in the catalysis of transformations such as the polymerization of monomers into polymers. The catalyst have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene to form isotactic polypropylene.

Abstract: Particle and multi-phase system monitoring methods, systems and apparatus are disclosed. Preferred embodiments comprise one or more mechanical resonator sensing elements. In preferred embodiments a sensor or a sensor subassembly is ported to a fluidized bed vessel such as a fluidized bed polymerization reactor.

Abstract: An improved metal alloy composition for a fuel cell catalyst containing platinum, manganese, and cobalt.

Abstract: The invention is directed to a dispensing unit suitable to precisely dispense material in powdery and/or granular form. The dispensing device comprises an gate valve opening sealingly closed by a blend. A control unit, which is interconnected to a scaling device, controls the opening of the gate valve opening by the position of the blend. The precise amount of the material is adjusted in relation to the signal of the scaling device.

Abstract: Apparatus and methods for screening a library of materials. Materials are provided in a plurality of locations on a substrate. The locations include first regions that are sufficiently transparent to a first form of radiation to permit analysis of the portion of the sample material supported in the first region using a first analytical technique, and second regions that are sufficiently transparent to a second form of radiation to permit analysis of a portion of the sample supported in the second region using a second analytical technique, but are insufficiently transparent to the first form of radiation to permit analysis of the portion of the sample material supported in the second region using the first analytical technique. Sample materials are screened at one or more sample locations of the substrate using the first analytical technique in the first region and the second analytical technique in the second region.
