16 p, 1.4 MB Hydrothermal synthesis, between 75 and 150°C, of high-charge, ferric nontronites / Decarreau, Alain (Université de Poitiers. UMR 6532 HydrASA. CNRS/INSU) ; Petit, Sabine (Université de Poitiers. UMR 6532 HydrASA. CNRS/INSU) ; Martin, François (ERT 1074 CNRS Géomatériaux. LMTG-OMP-UPS-IRD. CNRS) ; Farges, François (USM 201 - UMR CNRS 7160.

High-charge nontronites were synthesized at 75, 90, 100, 110, 125, and 150°C from a silicoferrous starting gel with SiFeNa O. nHO Composition. This gel was oxidized in contact with air and then hydrothermally treated, for a period of 4 weeks, under equilibrium water pressure. [...]

11 p, 891.4 KB XAS study of Fe mineralogy in a chronosequence of soil clays formed in basaltic cinders / Baker, Leslie L. (University of Idaho. Soil and Land Resources Division) ; Strawn, Daniel G. (University of Idaho. Soil and Land Resources Division) ; Vaughan, Karen L. (United States Department of Agriculture. Natural Resources Conservation Service (NRCS-USDA)) ; McDaniel, Paul A. (University of Idaho. Soil and Land Resources Division)
The characterization of poorly crystalline minerals formed by weathering is difficult using conventional techniques. The objective of this study was to use cutting-edge spectroscopic techniques to characterize secondary Fe mineralogy in young soils formed in basaltic cinders in a cool, arid environment. [...]

18 p, 1.4 MB Ultrathin High Surface Area Nickel Boride (NixB) Nanosheets as Highly Efficient Electrocatalyst for Oxygen Evolution / Masa, Justus (Ruhr-Universität Bochum (Alemanya)) ; Sinev, Ilya (Ruhr-Universität Bochum (Alemanya)) ; Mistry, Hemma (Ruhr-Universität Bochum (Alemanya)) ; Ventosa, Edgar (Ruhr-Universität Bochum (Alemanya)) ; De La Mata, Maria (Institut Català de Nanociència i Nanotecnologia) ; Arbiol i Cobos, Jordi (Institut Català de Nanociència i Nanotecnologia) ; Muhler, Martin (Ruhr-Universität Bochum (Alemanya)) ; Roldan Cuenya, Beatriz (Ruhr-Universität Bochum (Alemanya)) ; Schuhmann, Wolfgang (Ruhr-Universität Bochum (Alemanya))
The overriding obstacle to mass production of hydrogen from water as the premium fuel for powering our planet is the frustratingly slow kinetics of the oxygen evolution reaction (OER). Additionally, inadequate understanding of the key barriers of the OER is a hindrance to insightful design of advanced OER catalysts. [...]
