    Suggestions for the operation of radial flow cells in cell adhesion and biofouling studies (1985)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 27 (1985), S. 434-438 
    Details
    ISSN: 0006-3592
    Keywords: Chemistry ; Biochemistry and Biotechnology
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: An analysis of the radial flow cell is presented to show that the assumption of creeping laminar flow should be used cautiously. Simple models which account for the influence of fluid inertial forces over most of the width of the plate are reviewed. A modified Reynolds number is introduced which may be used to test the validity of the creeping flow solution.

    Interfacial reactions between Al and RuO2, MoOx and WNx diffusion barriers on Si (1989)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 14 (1989), S. 7-12 
    Details
    ISSN: 0142-2421
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Physics
    Notes: The Interfacial reactions between Al and RuO2, MoOx and WNx diffusion barriers on Si (100) wafers have been studied. The diffusion barrier structures were analyzed before and after various heat treatments using Auger electron spectroscopy (AES) and cross-sectional transmission electron microscopy (XTEM). Al was found to reduce the oxides of both Ru and Mo. A 100 Å thick Al2O3 layer developed between the Al and the RuO2 films during annealing at 500°C for 30 minutes. The formation of interfacial Al2O3 efficiently prevents Al penetration but may cause a too high contact resistance for applications in contact structures of microelectronic devices. The WNx barrier was stable after annealing at 600°C for 30 minutes, if the film was exposed to air prior to Al deposition. If, instead, the Al was deposited in situ, the structure failed after annealing at 500°C due to a reaction between Al and W giving WAl12. A thin Al2O3 layer was detected between the Al and the WNx films of the air exposed sample. This layer had the effect of retarding the Al-W reaction and thereby raised the failure temperature of the barrier by at least 100°C.

    Examination of Wax-Coated RDX by scanning electron microscopy and X-ray photoelectron spectroscopy (1985)
    Weinheim : Wiley-Blackwell
    Propellants, Explosives, Pyrotechnics 10 (1985), S. 61-64 
    Details
    ISSN: 0721-3115
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) have been used to examine the nature and quality of wax-coated RDX crystals. SEM allows a visual assessment of wax-coated crystals and comparison of different coating processes. XPS has allowed a semiquantitative determination of the degree of wax coverage by measurement of the carbon to nitrogen photoelectron emissions and calculation of the percentage of wax coverage using a simple mathematical treatment.
