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…
Structural relaxation around substitutional Cr3+ in pyrope garnet
Amélie Juhin, Georges Calas, Delphine Cabaret +2
The structural environment of substitutional Cr3+ ion in a natural pyrope Mg3Al2Si3O12 has been investigated by Cr K-edge Extended X-ray Absorption Fine Structure (EXAFS) and X-ray…
XANES determination of chromium oxidation states in glasses: comparison with optical absorption spectroscopy
Olivier Villain, Georges Calas, Laurence Galoisy +2
The oxidation state of chromium in glasses melted in an air atmosphere with and without refining agents was investigated by Cr K-edge X-ray Absorption Near-Edge Structure (XANES) a…
Structural relaxation around substitutional Cr3+ in MgAl2O4
Amélie Juhin, Georges Calas, Delphine Cabaret +2
The structural environment of substitutional Cr3+ ion in MgAl2O4 spinel has been investigated by Cr K-edge Extended X-ray Absorption Fine Structure (EXAFS) and X-ray Absorption Nea…
Hydrogen bonding and coordination in normal and supercritical water from X-ray inelastic scattering
Patrick H. -L. Sit, Christophe Bellin, Bernardo Barbiellini +5
A direct measure of hydrogen bonding in water under conditions ranging from the normal state to the supercritical regime is derived from the Compton scattering of inelastically-sca…
