    Notes:
    Si1−xGex/Si strained-layer superlattices grown by molecular-beam epitaxy on Si substrates were investigated by x-ray double-crystal diffraction and x-ray grazing incidence diffraction. Both coherent and incoherent interfaces between the two components of the superlattices were observed. By fitting computer-simulated double-crystal x-ray-diffraction rocking curves to the experimental data, it is determined that there exist graded variations in both the component thickness ratio t1/t2 (t1 and t2 are the thickness of the Si1−xGex and the Si layers, respectively) and the fraction x in one sample. The x-ray grazing incidence diffraction experiments reveal a lattice strain relaxation of about 27% in another sample. The lattice relaxation and the influence of variations of x and t1/t2 on the rocking curves are discussed.

    Notes:
    Measurements of infrared and visible emission in a macroscopic discharge cell similar to a plasma display panel (PDP) cell are analyzed using a two-dimensional fluid model of the discharge. The comparisons between experiments and models show a good qualitative agreement but the plasma spreading velocity above the cathode surface is much faster in the experiments. We find that including photoemission (in a simplified way) in the model considerably increases the agreement between experiments and models. With a well-chosen photoemission coefficient, the model reproduces the trends observed in the experiments when the gas mixture (between 2% and 10% of xenon in neon) or the applied voltage is changed. The influence of photoemission on the current rise time and on the velocity of plasma spreading above the dielectric surfaces is more important in the macrocell than in a similar (same dimension × pressure) PDP cell because resonant photon transport does not follow the similarity laws. © 2002 American Institute of Physics.

    Notes:
    The space and time variations of the light emission in a macroscopic plasma display panel (PDP) discharge cell have been studied with an image-intensified charge-coupled device. The discharge cell is similar to a real PDP cell with a coplanar electrode configuration. The cell dimensions are on the order of 100 times larger than those of a real PDP cell and the operating pressure is about 100 times smaller. Different xenon–neon gas mixtures have been investigated. Optical filters have been used to measure infrared emission from xenon excited states 823.1 and 828.0 nm, and visible emission from neon at 640.2 nm. The measurements show that the neon visible emission occurs only above the cathode while xenon infrared emission occurs above both cathode and anode. Standing striations can be observed above the anode. The strong xenon emission above anode indicates that this region is more efficient than the cathode region in terms of ultraviolet production. The measurements are in excellent qualitative agreement with similar measurements performed in real PDP cells. However the velocity of plasma spreading above the cathode in the macrocell is significantly larger than in a real PDP cell. The interpretation of this discrepancy is given in a companion paper (part II) [J. Appl. Phys. 91, 1000 (2002)] where the experimental results are compared with results from a fluid model of the plasma. © 2002 American Institute of Physics.

    Notes:
    Decomposition products of β-carotene formed during a simulated commercial deodorization of palm oil were separated from unsaponifiable portion into six fractions by liquid chromatography. Fraction two containing slightly polar substances was further separated using thin-layer chromatography and high performance liquid chromatography. In this fraction, β-13-apo-carotenone, β-15-apo-caro-tenal, and β-14′-apo-carotenal were identified by infrared spectrometry and mass spectroscopy.

    Abstract The microstructure and dry sliding wear behaviour of XDTM ZL201–TiB2 in situ composite were studied by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, pin-on-ring friction and wear testing. The microstructural constituents of the ZL201–TiB2 composite aged at 175°C for various ageing times were found to be dispersive submicrometre TiB2 particles, fine θ″, θ′-precipitates and α-Al solid solutions. As contrasted to the unreinforced ZL201 alloy, the ZL201–TiB2 composite possessed a higher microhardness and wear-resistance as well as a shorter ageing time for peak hardness. With the increase of sliding distance, transition of the dominant wear mechanism for the ZL201–TiB2 composite occurred from adhesive wear to fatigue wear in sliding contacts. At the earlier stages of wear, adhesive wear characteristics featured by mild scratchings and plastic smearing were observed on the worn surface and platelet-type wear debris; but at the later stages, contact fatigue failure of a relatively thick surface layer in relative motion, which revealed a build-up of layer-like structure and the presence of spherical particles of debris, became the dominant factor for the removal of composites. © 1998 Chapman & Hall

    Notes:
    Summary The response of anther culture to culture temperature was studied in detail using many varieties, F1 hybrids and pollen-derived lines of wheat (Triticum aestivum) as materials. The suitable culture temperature for inducing pollen callus (or embryoids) in wheat anther culture ranged from 26 °C to 30 °C, varying with genotypes. But for the great majority of wheat genotypes the suitable culture temperatures lay between 28 °C and 30°C. The most significant genotypic variation in the response to culture temperature was observed in the comparison between the culture at 33 °C for eight days followed by culture at 25 °C (or 26 °C) and the continuous culture at 25 °C (or 26 °C). This genotypic variation in the response to culture temperature is a heritable character which may be controlled by multiple genes. The effect of culture at 30 °C for eight days followed by culture at 26 °C was similar to, or in some cases, better than that of continuous culture at 28 °C, and the effect of culture at 32 °C for eight days followed by culture at 28 °C was similar to that of continuous culture at 30 °C. In the range from 26 °C to 32 °C, the overwhelming majority of pollen calli emerged before the 40th day after anther inoculation, and the higher the culture temperature, the earlier and more concentrated the emerging period of the pollen callus. The pollen callus obtained at high temperatures above 28 °C should be transferred in time onto the regeneration medium at 25°–27°C to induce shoots.

    Notes:
    Abstract The composition gradient in an InAlAs epitaxial layer on InP (0 0 1) substrate has been investigated using an X-ray double-crystal diffraction technique and a computer simulation method. Good agreement has been obtained between theoretical and experimental rocking curves when the correct graded layers are assumed in the samples. The results show that the graded layer introduces very sensitive asymmetric changes in layer peak and interference fringes. The intensities of the interference increase more strongly on the higher or lower angle side, while they are reduced on the other side, and the layer peak shifts to the higher or lower angle direction according to the positive or negative gradient. In all cases, however, the angle separations of the interference fringes do not change if the total thickness of the epilayer is unchanged.
