    Notes: Summary Seeds of forty bean cultivars having different lectin types based on two-dimensional isoelectric focusing-sodium dodecyl sulfate polyacrylamide gel electrophoresis (IEF-SDS/PAGE) were analyzed for quantities of lectin, phaseolin and total protein. Significant differences were found among groups of cultivars with different lectin types for the quantity of lectin and phaseolin. Cultivars with more complex lectin types based on IEF-SDS/PAGE tended to have higher quantities of lectin and lower quantities of phaseolin than cultivars with simple lectin types. An association between lectin type and the quantity of lectin and phaseolin was found also in the seeds of F2 plants that segregated in a Mendelian fashion for two lectin types. Seeds from plants with the complex lectin type had more lectin and less phaseolin than seeds from plants with the simple lectin type. Therefore, the genes controlling qualitative lectin variation also may influence the quantitative variation of lectin and phaseolin. The results of this study are related to other studies on the quantitative variation for seed proteins and to the possible molecular basis for variation in the quantity of lectins in beans.

    Description / Table of Contents: Einfluß von Chlorwasserstoff auf die Korrosion einer FeCrAlY-Legierung in einer simulierten KohlevergasungsatmosphäreEie Chrom-Aluminium-Yttrium-Stahl wurde einer simulierten Kohlevergasungsatmosphäre ausgesetzt die 1000 ppm bzw. 2200 ppm Chlorwasserstoff enthielt und deren Temperatur 450 °C betrug. Durch Erhöhen des Chlorwasserstoffgehalts werden die Reaktionsgeschwindigkeit erhöht und die Mikrostruktur sowie die Zusammensetzung des Korrosionsprodukts beträchtlich verändert. Für diese Ergebnisse werden versuchsweise Mechanismen postuliert, nach denen Metallchloride über die Gasphase transportiert werden.
    Notes: An iron chromium aluminium yttrium steel was exposed to a simulated coal gasifier atmosphere containing 1000 ppm and 2200 ppm hydrogen chloride at 450 °C. Increasing hydrogen chloride content was found to accelerate reaction rates, and significantly alter the microstructure and composition of the corrosion product. Tentative explanations for these results, involving vapour phase transport of metal chlorides are proposed.

    Notes: A scanning system has been installed on a Cameca IMS 3f ion microscope. The system has been invaluable for alignment of secondary ion extraction to the centre of the crater during depth profiling, detection of inclusions and lateral inhomogeneities during depth profiling and compensation of charging of insulators using an electron flood gun. Limitations of the standard gun have become apparent.

    Stabilization of charge on electrically insulating surfaces during SIMS experiments - experimental and theoretical studies of the specimen isolation method (1985)
    Chichester [u.a.] : Wiley-Blackwell

    Notes: Recent experiments have shown that secondary ion mass spectrometric (SIMS) measurements of insulator surfaces can be greatly facilitated by the use of a charged aperture located immediately above the analysis area (the ‘specimen isolation technique’). This allows the surface potential within the aperture area to be stabilized. Charging is stabilized when the potential difference between the surface and the aperture becomes large enough that excessive charge, in the form of secondary electrons, is drained away from the surface to the aperture. The potential difference generated on such insulating surfaces can be measured experimentally by varying the voltages applied to the electrostatic analyzer to measure the secondary ion intensity as a function of kinetic energy. Such measurements have been carried out on a Cameca IMS-3F instrument for a range of aperture dimensions and for different primary and secondary ions. The surface potential can be stabilized at a potential readily measurable by the electrostatic analyzer for both O- and Cs+ ion beams. The mechanism for this stabilization has been analyzed through calculations of two dimensional contours for the region around the specimen holder. For surfaces with a very high charging potential (〉600 V), potential wells which can trap ions of low kinetic energy develop near the surface. Element and oxide secondary ion kinetic energy distribution curves, taken under specimen isolation conditions, which differ from those obtained under normal non-charging SIMS conditions, are evidence for such ion trapping.
