The iron record of asteroidal processes in carbonaceous chondrites
A. Garenne, P. Beck, G. Montes-Hernandez +4
The valence of iron has been used in terrestrial studies to trace the hydrolysis of primary silicate rocks. Here, we use a similar approach to characterize the secondary processes,…
Modelling the Pb release during Portland cement alteration
A. Benard, J. Rose, Jean-Louis Hazemann +6
Complex cementitious matrices undergo weathering with environmental exchange and can release metallic pollutants during alteration. The molecular mechanisms responsible for metal r…
Emergence of ferromagnetism and Jahn-Teller distortion in low Cr-substituted LaMnO3
A. Y. Ramos, H. C. N. Tolentino, O. Bunau +9
The emergence of a ferromagnetic component in with low Cr-for-Mn substitution has been studied by x-ray absorption spectroscopy and x-ray magnetic circular dichroism at…
Electrochemical lithium intercalation in nanosized manganese oxides
Pierre Strobel, Céline Darie, François Thiéry +4
X-ray amorphous manganese oxides were prepared by reduction of sodium permanganate by lithium iodide in aqueous medium (MnOx-I) and by decomposition of manganese carbonate at moder…
Hard x-ray spectroscopy in NaxCoO2 and superconducting NaxCoO2 - yH2O: A view on the bulk Co electronic properties
Philippe Leininger, J. -P. Rueff, J. -M. Mariot +6
The electronic properties of Co in bulk Na0.7CoO2 and the superconducting hydrated compound Na0.35CoO2 - y H2O have been investigated by x-ray absorption spectroscopy (XAS) and res…
