  • Formation of combinatorial arrays of materials using solution-based methodologies
    Publication number: 20030219906
    Abstract: A combinatorial method for discovering or optimizing materials is disclosed. The method uses solution-based components that are mixed and dispensed into regions on a substrate for drying and/or heat-treating. The drying and/or heat-treating produces materials that can be tested for a desired property.

  • Synthesis and characterization of materials for electrochemical cells
    Publication number: 20030070917
    Abstract: An apparatus including a basis that has a plurality of wells associated therewith for defining a plurality of electrochemical cells; at least two electrodes sealingly disposed in each electrochemical cell; and circuitry for providing an electrical connection between an electrical source and each said cell. A particularly preferred apparatus employs at least one printed circuit board secured to the base. In a preferred method, candidate materials are introduced into the apparatus and their respective performances are analyzed.

  • High throughput crystallographic screening of materials
    Publication number: 20030068829
    Abstract: A method for characterization of a solid material sample, including the steps of providing a liquid medium for delivering a solid material sample to a porous substrate. Solid sample is separated from the liquid medium by filtering through the porous substrate. Analysis such as x-ray analysis of the solid sample is conducted while the sample resides on the porous substrate.
