    Photoemission study of the electronic structure of LaFeAsO 1-xFx and LaFePO1-xFx حسب Malaeb, Walid

    منشور في 2008
    "…In going from the undoped to F-doped compounds, all the spectra are found to shift to higher binding energies, consistent with electron doping within the rigid-band model. Also, in going from LaFeAsO1-xF x to LaFePO1-xFx, the near-EF intensity increases reflecting the weakening of electron correlation.…"

    Pyrite (FeS2)-supported ultrafiltration system for removal of mercury (II) from water حسب Dong Suk Han (1748989)

    منشور في 2022
    "…The reaction mechanism between Hg(II) and pyrite and the rejection of the solids over time were characterized with respect to flux decline, pH change, and Hg and Fe concentration in permeate water. Effects of the presence of anions (Cl−, SO42−, NO3−) or humic acid (HA) on the rejection of the Hg(II)-contacted pyrite were studied. …"
