    Notes: The surface properties of oxidized and sized (epoxy and epoxy-polyester) carbon fibres have been determined with inverse phase gas chromatography. Using a column developed in the laboratory we have shown that it is possible to use non-aggressive solvents (alkanes, alcohols, aromatic derivatives and water) for a highly detailed differentiation of sizing and of the treatments undergone by the fibre by the use of partition coefficient (K°) values (at a given temperature), excess enthalpy values of the mixture and excess entropy values.We propose a classification of fibres according to their degree of sizing and treatment.

    SAFT nickel hydrogen cell cycling status (1994)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: An overview of the NiH2 cell development is given. The NiH2 SAFT system is an electrochemical (single or dual) stack (IPV). The stack is mounted in an hydroformed Inconel 718 vessel operating at high pressure, equipped with 'rabbit ears' ceramic brazed electrical feedthroughs. The cell design is described: positive electrode, negative electrode, and stack configuration. Overviews of low earth orbit and geostationary earth orbit cyclings are provided. DPA results are also provided. The cycling and DPA results demonstrate that SAFT NiH2 is characterized by high reliability and very stable performances.
