  • Publication number: 20160322224
    Abstract: The present invention provides methods for using single source organometallic precursors in the fabrication of polycrystalline Group III-Group V compounds, preferably semiconductor compounds. The present invention teaches how to select organometallic ligands in single-source precursors in order to control the stoichiometry of the corresponding Group III-Group V compounds derived from these precursors. The present invention further teaches how to anneal precursors in the presence of one or more flux agents in order to increase the crystalline grain size of polycrystalline Group III-Group V compounds derived from organometallic precursors. This helps to provide Group III-Group V semiconductors with better electronic properties. The flux layer also helps to control the stoichiometry of the Group III-Group V compounds.

  • Patent number: 8808807
    Abstract: Novel membranes based on functionalized porous inorganic materials for ion exchange and conduction have been synthesized and characterized. The preparation procedure of these new membranes involves the synthesis of porous inorganic films, into which hydrophilic moieties are incorporated along the interior pore surfaces of the inorganic framework. Ion-conducting species are grafted into the pores via reactions with surface groups of the inorganic framework to allow for ion transport through the pore network.

  • Patent number: 8758653
    Abstract: A material and method for producing mesostructured materials with multiple functionalities that are independently adjustable and collectively optimizable is provided. The method uses a series of discrete synthesis steps under otherwise mutually incompatible conditions, e.g., from acidic, alkaline, and/or non-aqueous solutions, allows different functionalities to be introduced to the materials and optimized. To illustrate the method, cubic mesoporous silica films were prepared from strongly acidic solutions that were separately functionalized under highly alkaline conditions to incorporate hydrophilic aluminosilica moieties and under non-aqueous conditions to introduce perfluorosulfonic-acid surface groups.
