    摘要： Novel chemical sensors that improve detection and quantification of CO2 are critical to ensuring safe and cost-effective monitoring of carbon storage sites. Fiber optic (FO) based chemical sensor systems are promising field-deployable systems for real-time monitoring of CO2 in geological formations for long-range distributed sensing. In this work, a mixed-matrix composite integrated FO sensor system was developed that reliably operates as a detector for gas-phase and dissolved CO2. A mixed-matrix composite sensor coating on the FO sensor comprising plasmonic nanocrystals and zeolite embedded in a polymer matrix. The mixed-matrix composite FO sensor showed excellent reversibility/stability in a high humidity environment and sensitivity to gas-phase CO2 over a large concentration range. The sensor exhibited the ability to sense CO2 in the presence of other geologically relevant gases, which is of importance for applications in geological formations. A prototype FO sensor configuration which possesses a robust sensing capability for monitoring dissolved CO2 in natural water was demonstrated. Reproducibility was confirmed over many cycles, both in a laboratory setting and in the field.

    摘要： Ferrite compositions, particularly ferrite coated substrates and more particularly fibre plys coated with ferrites in fibre reinforced polymer composites (FRPC), and composites with a plurality of functionalised fibre layers, include a magnetic ferrite composition for coating a substrate, said composition comprising a resin, and dispersed therein ferrite particulates, wherein said ferrite particulates have an average longest dimension of less than 500 nm. The composition may be used to provide a ferrite composite structure comprising at least one fibre ply, with at least one layer of a magnetic ferrite composition disposed thereon, wherein said ply is substantially encapsulated in a binder matrix to form a fibre reinforced polymer composite.

    摘要： A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises an addition product of an amine and a reactant to form an amino-amide intermediate. To the amino-amide is added an aldehyde or ketone to form the curable binder composition. The composition when applied to fiberglass is cured to form a water-insoluble binder which exhibits good adhesion to glass. In a preferred embodiment the fiberglass is in the form of building insulation. In other embodiments the product is a microglass-based substrate for use in a printed circuit board, battery separator, filter stock, or reinforcement scrim.

    摘要： A contamination control mat 10 comprising a support layer 16 which is coated on a top surface with a polymeric contamination control layer 17, wherein the support layer 16 comprises a glass fibre reinforced polymer that is printed on a top surface, the polymeric contamination control layer 17 is transparent or translucent, and the printed surface is visible through the polymeric contamination control layer. This provides a thin yet rigid and stable mat 10 that can also display printed information that is protected from damage. The mat 10 is primarily used to meet contamination control needs.
