Journal ArticleDOI
Structure and reactivity of the hydrated hematite (0001) surface
Thomas P. Trainor,Anne M. Chaka,Peter J. Eng,Matthew Newville,Glenn A. Waychunas,Jeffrey G. Catalano,Gordon E. Brown +6 more
TL;DR: In this paper, the structure of the hydroxylated hematite surface was investigated using crystal truncation rod diffraction and density functional theory, and the combined experimental and theoretical results suggest that the surface is dominated by two hydroxym moieties, singly and doubly coordinated with Fe.
Journal ArticleDOI
Uranyl adsorption onto montmorillonite: Evaluation of binding sites and carbonate complexation
TL;DR: In this paper, Extended X-ray absorption fine structure (EXAFS) spectroscopy has been used to investigate the adsorption of uranyl (UO22+) onto Wyoming montmorillonite.
Journal ArticleDOI
Simultaneous inner- and outer-sphere arsenate adsorption on corundum and hematite
TL;DR: In this article, in situ resonant surface X-ray scattering measurements of arsenate adsorption at pH 5 in 0.01 M NaCl on corundum and hematite (012) surfaces demonstrate that arsenate surface complexation is unexpectedly bimodal, adsorbing simultaneously as inner and outer-sphere species.
Journal ArticleDOI
Ancient Aqueous Environments at Endeavour Crater, Mars

TL;DR: Rocks on the rim of the Noachian age Endeavour crater are investigated, where orbital spectral reflectance signatures indicate the presence of Fe+3-rich smectites, which would have been more favorable for prebiotic chemistry and microorganisms than those recorded by younger sulfate-rich rocks at Meridiani Planum.
Journal ArticleDOI
Adsorption of Uranium(VI) to Manganese Oxides: X-ray Absorption Spectroscopy and Surface Complexation Modeling
Zimeng Wang,Sung Woo Lee,Jeffrey G. Catalano,Juan S. Lezama-Pacheco,John R. Bargar,Bradley M. Tebo,Daniel E. Giammar +6 more
TL;DR: U(VI) adsorption to synthetic δ-MnO(2) appears to be stronger than to biogenic MnO( 2), and the differences in adsorptive affinity and capacity are not associated with any substantial difference in U( VI) coordination.
