  • Patent number: 7563741
    Abstract: This invention relates to silicone compositions which can be crosslinked, preferably into elastomers, by hydrosilylation of at least one PolyOrganoSiloxane -A- carrying unsaturated bonds, using at least one polyorganohydrosiloxane —B— in the presence of a carbene-based metal catalyst —C— as defined in the description and which optionally comprises at least one inhibitor -D- of the hydrosilylation reaction.

  • Publication number: 20070077657
    Abstract: The invention provides methods, apparatus, and systems for performing high-throughput preparation and screening of salts and polymorphs 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. Another apparatus may filter the synthesized solution to provide a substantially pure mixture that can be subjected to salt or polymorph testing.

  • Patent number: 7076115
    Abstract: Computer programs and computer-implemented methods implement techniques for evaluating experimental data from a library of materials. The techniques receive a plurality of images of a library of materials that includes an array of members associated with locations in the library. User input identifying a plurality of regions of interest is received. A series of reduced data values is determined for one or more of the regions of interest as a statistical function of a plurality of pixel values for pixels in the corresponding regions. A figure of merit is calculated from one or more of the series of reduced data values for a library member at the corresponding library location. The regions of interest include a plurality of pixels in the images and correspond to locations in the library.

  • Patent number: 6738529
    Abstract: Computer programs and computer-implemented methods are disclosed for extracting and analyzing combinatorial chemical data from images. The invention receives a stream of data, identifies a plurality of regions of interest and determines a series of values for one or more regions of interest. The library includes a plurality of members. The data stream includes a series of images of the library. Each region of interest corresponds to a location in each of the images and to a location in the library. The series of values for each region includes a value for each of the images. Particular embodiments have the following features. The invention calculates a figure of merit for a library member from each series of values. The stream of data comprises a series of images generated at a frequency of greater than about 1, 6, 12 or 30 frames per second. The series of images is captured from a beginning of a combinatorial experiment to an end of a commercial experiment.

  • Patent number: 6727361
    Abstract: New ligands, compositions, metal-ligand complexes and arrays with pyridyl-amine ligands are disclosed that catalyze the polymerization of monomers into polymers. Certain of these catalysts with hafnium metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, isobutylene or styrene. Certain of the catalysts are particularly effective at polymerizing propylene to high molecular weight isotactic polypropylene in a solution process at a variety of polymerization conditions.
