    Springer
    International journal of thermophysics 20 (1999), S. 677-690 
    Details
    ISSN: 1572-9567
    Keywords: liquid metals ; liquid alloys ; Lorenz relation ; resistivity ; thermal conductivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A four-probe dc technique for measuring liquid-metal electrical resistivities has been developed, and liquid-resistivity measurements on gallium, tin, lead, copper, a lead tin alloy, a copper tin alloy, and a zinc alloy have been presented. The Lorenz relation has been used to calculate thermal conductivities from these resistivity measurements. The thermal conductivities calculated from these resistivity measurements are (where data are available) in good agreement with recommended liquid-metal thermal conductivities.

    Some Thermal Properties of a Copper–Tin Alloy (1999)
    Springer
    International journal of thermophysics 20 (1999), S. 1051-1060 
    Details
    ISSN: 1572-9567
    Keywords: copper ; liquid metals ; liquid alloys ; Lorenz relation ; resistivity ; thermal conductivity ; thermal diffusivity ; tin
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The thermal properties (heat capacity, thermal diffusivity, and electrical resistivity) of a Cu + 10 wt% Sn alloy in both solid and liquid phases have been reported. Using these values it was confirmed that the Lorenz relation is suitable for obtaining thermal conductivity from electrical resistivity in the liquid phase of this alloy. Also, the temperature differential (dλ/dT) obtained from such an approach was in excellent agreement with the thermal conductivity values calculated from thermal diffusivity.

    Interconversion of chemical species during analysis by gas chromatography/mass spectrometry (1994)
    New York, NY : Wiley-Blackwell

    Notes: The electron ionization mass spectra obtained, on two types of GC/MS instrument, of an impurity peak in a sample of fluorotrichloroethene (1) were those of two different compounds, viz., the epoxide of 1 and trichloroacetyl fluoride. Confirmation of the latter structure was provided by evidence from infrared spectroscopy. A study, on both instruments, of the variation of injector, source and interface temperatures has shown that the sample impurity is actually the epoxide which, at sufficiently high interface-region temperatures, can be converted to the acyl fluoride species. Ab initio molecular orbital calculations have confirmed that the acyl fluoride is more stable than the epoxide.

    A fast-atom bombardment tandem mass spectrometry screening procedure for the presence of involatile sulphonated dyestuff intermediates (1990)
    New York, NY : Wiley-Blackwell

    Topics: Physics
    Notes: The introduction of more rigorous regulations aimed at controlling the use of sulphonated dyestuffs and dyestuff intermediates has pointed to the need for screening methods for the presence of these involatile compounds. Although much work has been caried out recently on the mass spectrometric behaviour of these compounds, it has been concerned principally with the production of molecular weight information using novel ionization methods rather than with any attempt to obtain structurally diagnostic fragment ions. In this mass spectrometric investigation of a range of naphthalene sulphonic acid salts, positive-ion and negative-ion fast-atom bombardment (FAB) mass spectra have been obtained and FAB-tandem mass spectrometry (MS/MS) has been used to acquire spectra (daugher-ion, parent-ion and neutral-loss) in an attempt to develop a useful screening method. On known compounds, best results were found when using a negative-ion neutral-loss scan to detect the loss of 64 mass units (corresponding to loss of SO2). This was confirmed by successful use of this scan to screen a sample of sulphonate residues.

    Synchronized collision-cell energy ramping. Improving the quality of product-ion spectra (1992)
    New York, NY : Wiley-Blackwell

    Topics: Physics
    Notes: The design and use of an RF-only collision-cell ramp generator is described. The generatio controls the collision energy voltage applied to the RF-only collision cell in a hybrid mass spectrometer of BEqQ geometry. The generator enables the collision-cell voltage to be increased or decreased in a linear ramp, over the full 500 V available. The start/stop functions of the ramp are synchronized under data system control to the scan of the quadrupole mass analyser. The collision-induced dissociation spectra so produced show an increase in the product ion abundance.

    Thin layer chromatography/mass spectrometry: The advantages of tandem mass spectrometry (1992)
    New York, NY : Wiley-Blackwell

    ISSN: 0951-4198
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Physics
    Notes: The results of thin layer chromatography/mass spectrometry (TLC/MS) and thin layer chromatography/tandem mass spectrometry (TLC/MS/MS) experiments are described. Spectra from the analytes were obtained directly from the absorbent without the need for extraction prior to analysis by mass spectrometry. These results illustrate the added specificity that the tandem mass spectrometer can afford in the detection and characterization of a range of compounds separated by TLC.

    Differential expression of type XIV collagen/undulin by human mammary gland intralobular and interlobular fibroblasts (1998)
    Springer
    Cell & tissue research 291 (1998), S. 507-511

    Notes: Abstract  Immunolocalisation of type XIV collagen/undulin in the human mammary gland revealed greater deposition in the interlobular stroma than in the intralobular stroma. The interlobular stroma is located between the breast lobules and their associated intralobular stroma. Fibroblasts isolated from the interlobular stroma synthesised 3- to 5-fold more type XIV collagen/undulin than intralobular fibroblasts, but synthesised type I and type IV collagens in similar amounts. The differential expression of type XIV collagen/undulin was maintained with passage in culture. The results suggest a role for type XIV collagen/undulin in stabilising dense collagen fibrils. The maintenance of two types of structurally distinct stromas may be important during developmental processes in the mammary gland.
