    Photosensitive polyimidesiloxanes (1992)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: Photosensitive polyamic acid involving substituted 3, 5-diaminobenzamide has been developed for photopatternable polyimidesiloxanes. This precursor, formulated with photosensitizers, was used to develop fine patterns by i-line UV exposure. The curing of polyamic acid was investigated by using FTIR and physical property measurement. The cured film has a high glass transition temperature depending on the siloxane content. It is stable up to 400°C and loses some of the substituted groups on heating to 500°C. The modulus, dielectric constant, and water absorption decreased with higher siloxane content.

    A study of chain addition polymerizations with temperature variations: II. Thermal runaway and instability - a computer study (1976)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 16 (1976), S. 101-116 
    Details
    ISSN: 0032-3888

    Notes: A computer study was made to determine the thermal ignition criteria and ignition boundaries for chain-addition polymerization in a well-mixed batch system using a simple kinetic model. The occurrence of thermal runaway was shown to be a function of initiator type, feed conditions, and heat transport parameters. It was found that thermal runaway does not occur early with respect to monomer and initiator conversions and that for strongly dead-ending systems, the sensitivity characteristic of ignition disappears. The role of various dimensionless parameters in characterizing reaction behavior is also discussed.

    Enzyme electrode for specific determination of L-lysine (1983)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 25 (1983), S. 2557-2566 
    Details
    ISSN: 0006-3592
    Keywords: Chemistry ; Biochemistry and Biotechnology

    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: L-Lysine α-oxidase from Trichoderma viride Y244-2 is immobilized in a gelatin support and fixed on a pO2 sensor. The enzyme electrode obtained is used in a continuous flow system in order to measure the concentration of L-lysine in a fermentor. The sample oxygen-content dependance of the signal is minimized because of the enzyme support properties. The enzyme electrode response is set for lysine concentration from 0.2mM to 4mM. The specificity of lysine is tested with other amino acids. The enzyme membrane for lysine electrode can be used 3000 times or stored six months with good stability.

    The resonance Raman spectra of some cyanine dyesThis work was supported by The National Science Foundation, grant number PCM-8202840. (1985)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 16 (1985), S. 319-321

    Notes: The resonance Raman spectra of a series of cyanine dyes, with various lengths of the methine chain, have been obtained. This series consists of the 1,1′-diethyl-2,2′-quino group basic structure. Raman spectra of some dyes with closely related structures were also measured. The Raman bands are assigned to normal modes arising from particular molecular moieties. For comparison purposes, the IR spectra of these dyes are also presented.
