  • Publication number: 20100284860
    Abstract: An article is provided for immobilizing functional organic biomolecules (e.g. proteins, DNA, and the like) through a covalent bond to a thiolate or disulfide monolayer to a metal surface wherein an extra activation step of the surface layer or an activation step of the functional biomolecules or bioreceptors could be avoided. The monolayer can contain, but is not limited to, two moieties. One has a group that resists nonspecific adsorption and another has a group that directly (without activation) reacts with functional groups on the biomolecules. In addition, poly(ethylene oxide) groups are incorporated in the monolayer surfaces to resist the nonspecific adsorption and to enhance the specific affinity interactions. A sensor device including these monolayers is also provided to perform reproducible, sensitive, specific and stable bioanalysis.

  • Patent number: 7034171
    Abstract: This invention relates to the reversible protection of hydroxy-silane functional groups by acid cleavable protecting groups. The development of reversible protecting groups greatly enhances the current utility of silanes while introducing further novel applications. For instance, reversibly protected silanes are of particular value in applications where room temperature cure and/or adhesion is of value, such as coatings, high resolution imaging, caulks, adhesives, sealents, gaskets, and silicones. Reversibly protected silanes can also be beneficially used in reticulating agents, and in sizing agents, tires, and release coatings. The incorporation of reversibly protected silanes into coating resins is of particular value. The reversibly protected silane can be incorporated into the coating resin by polymerizing a monomer containing the reversibly protected silane into the resin or by post-addition into the coating formulation.

Liquid precursors containing a plurality of metals have a longer shelf life. The addition of an organic dopant precursor compound containing a metal, such as niobium, tantalum or bismuth, to the liquid precursor enhances control of the conductivity of the resulting transparent conductor.

  • Patent number: 6355821
    Abstract: Methods of forming metal alkoxides and methods of forming precursor solutions of metal alkoxides suitable for the coating of glass in the manufacture of electrochromic devices are disclosed. The method of forming metal alkoxides involves dissolving the metal halide in an anhydrous solvent and reacting it with an alcohol and (together with the addition of the alcohol or subsequently) adding an epoxide, and then evaporating-off the volatile components of the reaction product to leave a solid metal alkoxide that is substantially free of halide. The alkoxide may then be dissolved in a solvent including an alcohol (preferably ethanol) containing a small proportion of water to produce a precursor solution suitable for coating glass, the coating then being hydrolyzed to form a sol-gel and then baked to remove volatile components and to yield a thin layer of metal oxide.

  • Patent number: 6278009
    Abstract: It is shown metallocenes with functionalized bridge of formula wherein M represents a transition metal of groups 3, 4, 5 or 6, L represents cyclopentadienyl-type ligands, Y represents a halogen and which can own one or various bridges between unities L. At least one of these bridges is functionalized through a group constituted by the union between a halogen atom and a silicon, germanium or tin atom. It is also shown a method for the synthesis of these metallocene compounds starting from the corresponding metallic halure and a precursor of the ligand which has leaving groups. These metallocene compounds are used as catalyst precursors for the homopolymerization and copolymerization of olefins. It is also shown methods for supporting these metallocenes on inorganic solids in order to obtain solid catalyst systems for olefins polymerization processes in a heterogeneous phase.
