摘要： The present invention provides novel silyl 2-amidoacetates and silyl 3-amidopropionates which are the reaction products of azlactone and silanol reactants. The novel products result from nucleophilic addition of a soluble or insoluble, low or high molecular weight reactant containing one or more silanol groups and a soluble or insoluble, low or high molecular weight reactant containing one or more azlactone groups. The reaction products provide for high adhesion between the siliceous and azlactone reactants, as would be useful as protective coatings particularly on silicon-containing materials. It has been recognized in the present invention that silyl 2-amidoacetates and silyl 3-amidopropionates are useful linkages between silanol and azlactone derived materials.

摘要： Methods and apparatus for performing Distributed Acoustic Sensing (DAS) using fiber optics with increased acoustic sensitivity are provided. Acoustic sensing of a wellbore, pipeline, or other conduit/tube based on DAS may have increased acoustic sensitivity through fiber optic cable design and/or increasing the Rayleigh backscatter property of a fiber's optical core. Some embodiments may utilize a resonant sensor mechanism with a high Q coupled to the DAS device for increased acoustic sensitivity.
