    High-temperature oxidation of Pt-45Pd-10Rh (1988)

    Notes: Abstract The surfaces of Pt-45Pd-10Rh foils oxidized over the range 875–1075 K in a 20% O2-Ar mixture at atmospheric pressure were examined by Auger electron, X-ray photoelectron, and Raman spectroscopy. The composition of the oxide formed on the surface was found to vary with temperature from predominantly PdO at 875 K to PdRhO2 at 1075 K. Only a few atomic percent Pt was observed, present in both the metallic and (apparently) +1 oxidation states at 875 K and in the metallic state at 1075 K. The formation of PdRhO2 (and no Rh2O3) at 1075 K was found to persist upon reoxidation following a low-temperature reduction cycle in which the increased Rh concentration on the surface was retained. An oxidation-induced Rh enrichment of the surface of the alloy foil beyond 50 at. % does not appear likely within the temperature/pressure regime investigated.

    PdRhO2 formation during the air oxidation of a Pd-15Rh alloy (1988)

    Notes: Abstract The surfaces of air-oxidized Pd-15Rh alloys have been examined by X-ray photoelectron spectroscopy (XPS) and by Raman spectroscopy. The XPS results indicate that the near-surface region of samples oxidized in the temperature range 1075 to 1125 K contains Pd in both the +2 and +1 oxidation states and Rh in the +3 oxidation state. The ratio of Pd (I) to Rh (III) is found to be 1∶1. Raman spectra confirm that two Pd-containing phases, PdO and PdRhO2, are present in the near-surface region and eliminate the possibility that Rh2O3 is present. Also, a resonant Raman effect is observed in anhydrous PdO for exciting wavelengths in the vicinity of 500 nm.

    A Cud-d excitation model for the pairing in the high-T c cuprates (1988)
    Springer

    Details

    Topics: Physics
    Notes: Abstract A new model for the pairing mechanism in the ceramic superconductors is presented. Like the magnetic models, we assume the limit of large correlation energies for the Cud electrons. We postulate that the pairing of the Op conduction holes occurs viad−d orbital excitations within thee g manifold of thed hole of Cu++, which is split because of tetragonal or lower symmetry at the Cu sites. This valence conserving charge degree of freedom has been ignored in the magnetic pairing models. Thed−d excitation model may provide a simple qualitative understanding of many experimental results.

    On the optimum grid size in field experiments without replications (1988)
    Springer
    Euphytica 39 (1988), S. 237-247

    Notes: Summary In unreplicated field trials a correction for soil heterogeneity is easily achieved by ‘gridding’, i.e. by expressing the observations as deviations from a local average. This paper investigates the problem of determining the optimum size of such a neighbourhood to be used in a moving average. The optimum grid size depends on two parameters, i.e. the ‘coarseness’ of the spatial variation of the trial field and the ratio of genotypic vs. non-genotypic variance. In general these parameters are not known to the breeder. We introduce a method for estimating these parameters from the data. From these estimates the optimum grid size can be obtained using tables presented in this paper. The method has been evaluated by applying it to a series of simulated data. It turned out that the agreement between estimated and true optimum grid size was satisfactory in these simulations. Some theoretical aspects of the results are discussed.
