  • Methods for the electrochemical detection of multiple target compounds
    Patent number: 7202028
    Abstract: A method of detecting two different target molecules through a single electrode is carried out by (a) providing a conductive oxidation-reduction reaction detection electrode; (b) contacting a sample suspected of containing a first and second target molecule to the electrode under conditions in which the first and second target molecules are deposited on the electrode, wherein the first target molecule comprises a first label and the second target molecule comprises a second label; (c) contacting to the electrode a first transition metal complex that oxidizes the first preselected label in a first oxidation-reduction reaction and a second transition metal complex that oxidizes the first and second labels in a second oxidation-reduction reaction, with the first and second oxidation-reduction reactions producing different detectable signals; (d) detecting the presence of the first target molecule by detecting the first oxidation-reduction reaction; and (e) detecting the presence of the second target molecule by

  • Compounds useful as chemical precursors in chemical vapor deposition of silicon-based ceramic materials
    Patent number: 5616754
    Abstract: In order to reduce the rate of coke formation during the industrial pyrolysis of hydrocarbons, the interior surface of a reactor is coated with a thin layer of a ceramic material, the layer being deposited by thermal decomposition of a non-oxygen containing silicon-nitrogen precursor in the vapor phase, tin an inert or reducing gas atmosphere in order to minimize the formation of oxide ceramics.

  • Method for passivating the inner surface by deposition of a ceramic coating of an apparatus subject to coking, apparatus prepared thereby, and method of utilizing apparatus prepared thereby
    Patent number: 5208069
    Abstract: In order to reduce the rate of coke formation during the industrial pyrolysis of hydrocarbons, the interior surface of the reactor tubes are coated with a thin layer of a ceramic material, said layer being deposited by thermal decomposition of a non-oxygen containing silicon organometallic precursor in the vapor phase, in an inert or reducing gas atmosphere in order to minimize the formation of oxide ceramics.
