    Use of oxygen-stabilized C60 films for selective chemical vapor deposition (1997)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 70 (1997), S. 586-588 
    Details
    ISSN: 1077-3118

    Topics: Physics
    Notes: Thin C60 films exposed to ultraviolet/visible light in the presence of oxygen were used as a selective mask for tungsten chemical vapor deposition on silicon substrates. An uptake of oxygen in the fullerene films as well as a significant increase in their thermal stability resulted from the simultaneous exposure to the radiation and oxygen. The thermal stability and inertness of these films to tungsten hexaflouride, which is readily reduced by silicon to form the metal at 350 °C, allowed selective deposition of tungsten in both ultrahigh vacuum and low pressure environments. X-ray photoelectron spectroscopy and x-ray fluorescence spectroscopy were used to characterize the tungsten deposited on the C60 mask and the unmasked silicon substrate. © 1997 American Institute of Physics.

    Mastering Logistics Change (1997)
    Bradford : Emerald
    The @international journal of logistics management 8 (1997), S. 45-54 
    Details
    ISSN: 0957-4093
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: This article draws attention to the how of logistics management or logistics as part of the learning organization. The logistics discipline has advanced over the years, but these advances have been mainly on the what side, what could be done rather than how it is done. In a world of increasing opportunities, the restraining factor is increasingly how. New product and market strategies depend upon supply chain redesign to be effective. Components and production skills can be purchased, as can transportation. But implementing new systems designs in an increasingly turbulent and complex world requires unprecedented skills of change management.

    Notes: [Auszug] Histidine and cysteine are known to form rather stable complexes with zinc and copper ions in nearly neutral aqueous solutions1. A gel loaded with strongly fixed Zn2+and Cu3+ions with excess binding capacity may therefore interact with surface-exposed imidazole and thiol groups of proteins. ...

    Development of an enzyme-linked immunosorbent assay for detection of Escherichia coli heat-stable enterotoxin (1984)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 23 (1984), S. 0 
    Details
    ISSN: 1574-6968

    Topics: Biology
    Notes: Abstract Purified heat-stable enterotoxin (ST), produced by human strain C57/26C2 of enterotoxigenic Escherichia coli, conjugated to human thyreoglobulin was used to raise rabbit antisera to develop an enzyme-linked immunosorbent assay (ELISA) specific for ST active in suckling mice and piglets (STa). This assay detected 15 pg of purified ST compared to 2 ng in the suckling mouse assay, and was specific for STa in culture supernatants from strains of porcine, bovine, and human origins. Neither heat-labile enterotoxin nor ST active in piglets but not in suckling mice (STb) cross-reacted in the ELISA. The detection of ST in culture supernatants by the ELISA showed an excellent correlation with the suckling mouse assay. In conclusion, the ELISA is a more convenient assay for detection of STa than the conventional suckling mouse assay.

    Mechanical properties and surface defects of boron fibres prepared in a closed CVD system (1979)
    Springer
    Journal of materials science 14 (1979), S. 966-974

    Notes: Abstract The tensile strength of boron fibres, prepared on a tungsten wire substrate suspended in a closed CVD system, has been investigated. The influence of strain-rate, gauge length, and fibre diameter on the tensile fracture stress of the fibres has been evaluated and compared to fracture stress data of fibres produced in continuous CVD processes. Moreover, the E-modulus of the prepared fibres has been measured. Finally the surface defects of the fibres have been examined and classified into fracture stress depressive surface defects and non-fracture stress depressive surface defects.

    Notes: Abstract The main surface morphologies of boron fibres in the temperature range 1000 to 1500° C and the relevant experimental conditions for obtaining them have been investigated. After tensile testing of boron fibres with the various main morphologies, an approximate value for the tensile fracture stress could be assigned to each morphology. A method for identifyingin situ the morphologies formed during the deposition process is described. Finally, the maximum preparation times for obtaining high-strength boron fibres at various temperatures have been calculated.

    Notes: Abstract The techniques for the preparation of boron fibres have been reviewed. The review contains a brief description of the following techniques: direct spinning, thermal decomposition of boranes, hydrogen reduction of boron halides and utilization of electrical discharges. In connection with the description of the dominating halide process various substrates are discussed, together with methods for increasing the deposition rate and methods for improving the tensile strength of the fibres after production. Finally, the tensile strengths of boron fibres produced by different techniques are compared.

    The initial stages of growth and the origin of proximate voids in boron fibres (1977)
    Springer
    Journal of materials science 12 (1977), S. 1750-1758 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The formation of so-called proximate voids (i.e. voids near the core-mantle interface) in boron fibres has been studied experimentally. The mantle growth was interrupted in very early stages of nucleation and growth of boron nodules on the tungsten wire substrate. Scanning electron microscope investigations of surface topography and cross-sections revealed a morphology of preferential nucleation of boron nodules along axial die-mark ridges on the tungsten wire surface, where tight parallel axial rows of growing nodules are formed which, particularly around deep wire surface grooves, may hedge in axially extended voids of a morphology earlier found to be typical of proximate voids. The physical conditions of this mechanism are studied with respect to geometry, surface energy and diffusion parameters.
