X-ray Standing Wave Based Internal Reference Method for Quantification of Implanted Fe in Genesis Samples
Introduction: NASA launched the Genesis Return Mission to obtain pristine solar wind. Unfortunately, the probe crash-landed necessitating the application of non-destructive methods that allows the differentiation of both the terrestrial contamination and low concentration solar wind from the substrate. Such techniques include x-ray standing wave (XSW) analysis, x-ray reflectivity and x-ray fluo...
متن کاملشکلهای مختلف فسفر در برخی خاکهای آهکی استان فارس و رابطه آنها با ویژگیهای فیزیکوشیمیایی خاک
Knowledge of forms of phosphorus (P) is important in the evaluation of soil P status and also in understanding soil genesis and fertility. Amounts and distribution of P in different organic and inorganic fractions were examined in 39 soil samples of Fars province. Soils were sequentially extracted to determine organic P and inorganic P fractions. Total P with an average of 597 mg/kg soil was ...

متن کاملChondritic meteorite fragments associated with the Permian-Triassic boundary in Antarctica.
Multiple chondritic meteorite fragments have been found in two sedimentary rock samples from an end-Permian bed at Graphite Peak in Antarctica. The Ni/Fe, Co/Ni, and P/Fe ratios in metal grains; the Fe/Mg and Mn/Fe ratios in olivine and pyroxene; and the chemistry of Fe-, Ni-, P-, and S-bearing oxide in the meteorite fragments are typical of CM-type chondritic meteorites. In one sample, the met...
