    Notes: An identifiedEnterobacter aerogenesutilizing methanol as a sole carbon source was studied for the optimization of biomass production and the reduction of its nucleic acid content. Results indicated that the highest yield and conversion were obtained at 0.5% methanol. The addition of seawater as a source of trace elements has an adverse effect. However, the addition of urea as source of nitrogen enhanced the growth of E. aerogenes. Heat shock at 60°C for 1 min followed by incubation at 50°C for 2 h caused 72.6% reduction in the nucleic acid.

    High-energy ion implantation of polymers: Poly(ethylene terephthalate) (1987)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part B: Polymer Physics 25 (1987), S. 817-827 
    Details

    Topics: Chemistry and Pharmacology , Physics
    Notes: The effect of high-energy ion implantation of oxygen into a thin film of poly(ethylene terephthalate) (PET) was studied by Fourier transform infrared spectroscopy and differential scanning calorimetry (DSC). Mylar samples 13 μm thick were implanted with 6-MeV oxygen ions at fluences ranging from 5 × 1012 to 2 × 1014 ions/cm2. The DSC data showed a substantial loss of crystallinity, even at the lowest fluence, which extended deeper into the polymer film than the predicted range for oxygen deceleration in PET. Solubility measurements indicated the presence of cross-linking, especially at the highest fluence, but bands due to cross-linking could not be detected in the infrared. The trans/gauche ratio for the glycol group conformation was measured by a pair of conformationally sensitive infrared bands. Surprisingly, the conformation of the glycol segments did not change appreciably with increasing fluence, although crystallinity decreased and degree of cross-linking increased. The implications these results have on possible mechanisms of chemical and physical alterations of the polymer structure by ion implantation are discussed.

    The infrared absorption characteristics of poly(methyl methacrylate) doped with luminescent materials (1987)

    Description / Table of Contents: Die Infrarotspektren von Poly(methylmethacrylat)-Probenn die mit verschiedenen lumineszierenden Substanzen dotiert wurden, weisen außer beim β-Naphthol keine wesentlichen Änderungen der Lage und Intensität der Absorptionsbanden auf. Daher wird angenommen, daß zwischen den meisten Dotierungsmitteln und PMMA keine Wechselwirkung besteht, während beim β-Naphthol zwischen benachbarten Molekülen in der Polymermatrix Wasserstoffbindungen auftreten.
    Notes: The infrared spectra of poly(methyl methacrylate) samples doped with different luminescent materials show no drastic changes in the position and intensity of the absorption bands, except in case of β-naphthol. From this it is supposed that there is no interaction between the dopant and PMMA with most of the investigated materials, while with β-naphthol hydrogen bonding between adjacent molecules in the polymer matrix is observed.
