    PHANEROZOIC ATMOSPHERIC OXYGEN (2003)

    Notes: Abstract Theoretical calculations, based on both the chemical and isotopic composition of sedimentary rocks, indicate that atmospheric O2 has varied appreciably over Phanerozoic time, with a notable excursion during the Permo-Carboniferous reaching levels as high as 35% O2. This agrees with measurements of the carbon isotopic composition of fossil plants together with experiments and calculations on the effect of O2 on photosynthetic carbon isotope fractionation. The principal cause of the excursion was the rise of large vascular land plants and the consequent increased global burial of organic matter. Higher levels of O2 are consistent with the presence of Permo-Carboniferous giant insects, and preliminary experiments indicate that insect body size can increase with elevated O2. Higher O2 also may have caused more extensive, possibly catastrophic, wildfires. To check this, realistic burning experiments are needed to examine the effects of elevated O2 on fire behavior.

    Evaluation of variability in Striga aspera, Striga hermonthica and their hybrids using morphological characters and random amplified polymorphic DNA markers (2000)
    Oxford UK : Blackwell Science Ltd

    Notes: Striga aspera and Striga hermonthica are recognized as separate species, but their close morphological similarity causes difficulty in distinguishing between them in areas where they coexist in Africa. In this study, crosses between the species were made using randomly selected morphologically typical parental plants collected from different locations in Nigeria. Genetic analysis of both species and their reciprocal F1 hybrids were determined using cluster analysis of DNA profiles derived from genetic polymorphism (RAPD)-polymerase chain reaction (PCR) markers. Principal component and hierarchical cluster analyses were used to separate parental and hybrid populations based on 13 morphological characteristics. Morphological data from wild samples of both species were compared with the hand-pollinated parental, F1 and F2 hybrids, and back-crosses. Results showed that S. aspera and S. hermonthica were genetically and morphologically distinct. Morphological and genetic analyses revealed two major clusters: a S. aspera cluster and a S. hermonthica cluster. Genetically, the F1 hybrids showed closer affinity to their maternal parents, while morphologically, the F1 hybrids formed distinct clusters intermediate to the parents. Most F2 plants and back-crosses were morphologically similar to S. hermonthica. Comparative morphological analysis of wild and hand-pollinated populations showed some samples from the wild clustered with the hybrids, suggesting that hybrids may exist in nature.

    Co silicide formation on epitaxial Si1−yCy/Si (001) layers (2000)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 87 (2000), S. 3306-3312 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We investigated the formation and structure of cobalt silicide (CoSi2) on Si1−yCy (0≤y≤0.81%) layers grown by molecular beam epitaxy on Si (001). The incorporation of C in the Si lattice causes the following phenomena during silicidation: (i) the formation of CoSi2 is delayed in temperature scale, as compared to pure Si; (ii) epitaxial CoSi2 grains are formed at T≥600 °C; (iii) a two sublayer structure of CoSi2 is observed, where the upper sublayer contains a very small amount of C and has a homogeneous microstructure, while the lower sublayer, which has a higher C concentration, contains randomly oriented CoSi2 nanocrystallites; (iv) spatial inhomogeneity results in significant variation (within ±40%) in the CoSi2 layer thickness; (v) no strain relaxation in the Si1−yCy layer during silicidation is detected up to 700 °C; and (vi) the distribution of carbon and boron in the semiconductor during silicidation is not changed significantly. The two latter findings show the potential of CoSi2 on Si1−yCy for device application despite the mentioned inhomogeneity in CoSi2 microstructure. © 2000 American Institute of Physics.

    Gas and fluid venting at the Makran accretionary wedge off Pakistan (2000)
    Springer
    Geo-marine letters 20 (2000), S. 10-19 
    Details
    ISSN: 1432-1157
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract The Makran accretionary complex shows a distinct bottom-simulating reflector, indicating a thick gas-hydrate-bearing horizon between the deformational front and about 1350 m water depth which seals off the upward flow of gas-charged fluids. A field of presently inactive mud diapirs with elevations up to 65 m was discovered in the abyssal plain seawards of the deformation front, suggesting that in the past conditions were favorable for periodic but localized vigorous mud diapirism. Regional destabilization of the gas hydrate leading to focused flow was observed where deep-penetrating, active faults reach the base of the gas-hydrate layer, as in a deeply incised submarine canyon (2100–2500 m water depth). At this location we discovered seeps of methane and H2S-rich fluids associated with chemoautotrophic vent faunas (e.g., Calyptogena sp.). Driven by the accretionary wedge dynamics, the landward part of the gas-hydrate layer below the Makran margin is being progressively uplifted. Due to reduced hydrostatic pressure and rising ocean bottom-water temperatures, gas hydrates are progressively destabilized and dissociated into hydrate water, methane and H2S. Sediment temperatures lie outside the methane stability field wherever water depth is less than 800 m. Above this depth, upward migration of fluids to the seafloor is unimpeded, thus explaining the abundance of randomly distributed gas seeps observed at water depths of 350 to 800 m.

    Notes: Abstract.  A method for quantitative analysis of Ti-Si-Ge/Si-Ge/Si structures with submicron thick layers by energy dispersive spectroscopy (EDS) in transmission electron microscopy (TEM) and Auger electron spectroscopy (AES) was developed. Quantitation of the results of both AES and EDS techniques was performed on the basis of a single reference specimen for the Ti-Si-Ge system comprising a uniform layer of the Ti(Si0.85Ge0.15)2 phase on a silicon substrate. The reference sample was prepared by the same procedure as the samples used in the study, and was thoroughly characterized by X-ray diffractometry, transmission electron microscopy and energy dispersive spectroscopy in scanning electron microscopy. Using this reference sample the elemental sensitivity factors relative to Si were found for both techniques, which enable us to obtain the elemental depth distributions for the studied samples. Good agreement between the results obtained by EDS/TEM, AES and supplementary techniques was found.

    Notes: Abstract.  The combination of energy dispersive spectroscopy (EDS) and electron backscatter diffraction (EBSD) techniques in scanning electron microscope was employed to characterize the reacted interface between Ti matrix and AlN particles. Due to the high localization of EDS and EBSD, representative measurements of chemical composition and reliable determination of the crystal structure were possible for each phase in the reaction zone with complex morphology. The TiN1−x (cubic, NaCl type), Ti3AlN (cubic, perovskite type) and Ti-rich Ti3 Al (hexagonal, Ni3Sn type) phases were identified in the reaction zone after annealing at 1100 °C. EDS+EBSD combination is an efficient tool for phase analysis at the interface in reactive multicomponent systems.
