  • Publication number: 20090045341
    Abstract: A system for monitoring the heats of reaction of an array of materials has an infrared transparent substrate containing the materials. A reaction chamber encloses the substrate. At least one reactant gas is coupled to the reaction chamber through a valve. An infrared camera images the array of materials. The camera outputs signals corresponding to an infrared emission intensity of at least one activated material in the array. A system for characterizing chemical reactions has an infrared transparent substrate for containing an array of materials. A modulated infrared radiation source simultaneously irradiates the materials in the array with infrared radiation. An infrared camera has a focal plane array detecting infrared radiation. An optical element focuses the infrared radiation transmitted by the array of materials onto the focal plane array. A processor coupled to the camera transforms sequential intensity profiles of the detected infrared radiation into infrared spectra using Fourier analysis.

  • Publication number: 20090002708
    Abstract: A system for monitoring infrared absorption of each of a plurality of materials contained in an array has an infrared transparent substrate for the array of materials. An infrared radiation source irradiates the materials in the array with infrared radiation. An infrared detection system monitors material absorption of the infrared radiation by the materials. A method of monitoring the infrared absorption spectrum of a library of materials includes synthesizing an array of material on a substrate. The materials are irradiated with infrared radiation and the absorption of the infrared radiation by the materials is monitored for each material.

  • Patent number: 7391056
    Abstract: Electron-hole production at a Schottky barrier has recently been observed experimentally as a result of chemical processes. This conversion of chemical energy to electronic energy may serve as a basic link between chemistry and electronics and offers the potential for generation of unique electronic signatures for chemical reactions and the creation of a new class of solid state chemical sensors. Detection of the following chemical species was established: hydrogen, deuterium, carbon monoxide, molecular oxygen. The detector (1b) consists of a Schottky diode between an Si layer and an ultrathin metal layer with zero force electrical contacts.

  • Patent number: 7364697
    Abstract: Methods and apparatus for screening diverse arrays of materials using infrared imaging techniques are provided. Typically, each of the individual materials on the array will be screened or interrogated for the same material characteristic. Once screened, the individual materials may be ranked or otherwise compared relative to each other with respect to the material characteristic under investigation. According to one aspect, infrared imaging techniques are used to identify the active sites within an array of compounds by monitoring the temperature change resulting from a reaction. This same technique can also be used to quantify the stability of each new material within an array of compounds. According to another aspect, identification and characterization of condensed phase products is achieved, wherein library elements are activated by a heat source serially, or in parallel.

  • Patent number: 7230150
    Abstract: In a method of converting alkanes to their corresponding alcohols, ethers, olefins, and other hydrocarbons, a vessel comprises a hollow, unsegregated interior defined first, second, and third zones. In a first embodiment of the invention oxygen reacts with metal halide in the first zone to provide gaseous halide; halide reacts with the alkane in the second zone to form alkyl halide; and the alkyl halide reacts with metal oxide in the third zone to form a hydrocarbon corresponding to the original alkane. Metal halide from the third zone is transported through the vessel to the first zone and metal oxide from the first zone is recycled to the third zone. A second embodiment of the invention differs from the first embodiment in that metal oxide is transported through the vessel from the first zone to the third zone and metal halide is recycled from the third zone to the first zone.

  • Patent number: 7199809
    Abstract: Computer-implemented methods, programs and apparatus for generating a library design for a combinatorial library of materials. A library design includes a set of sources representing components to be used in preparing the combinatorial library, destinations replying arrangements of cells and mappings, defining one or more distribution patterns for assigning components to cells in the destination arrangement or arrangements. Mappings include gradients and sets of user-defined equations, and are used to calculate the amount of on components to be assigned to a cell or cells in an arrangement. A library design can also include one or more process parameters defined to vary over time or across a plurality of destination cells. The invention outputs a data file defining the library design, including electronic data representing the sources, the destinations and the mapping, in a format suitable for implementing manually or using automated material handling apparatus.

    Abstract: A reactant selected from the group consisting of alkanes, alkenes, alkynes, dienes, and aromatics is reacted with a halide selected from the group including chlorine, bromine, and iodine to form a first reaction product. The first reaction product is reacted with a solid oxidizer to form a product selected from the group including olefins, alcohols, ethers, and aldehydes, and spent oxidizer. The spent oxidizer is oxidized to form the original solid oxidizer and the second reactant which are recycled.
