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…
EXAFS study of lead-free relaxor ferroelectric BaTi(1-x)Zr(x)O3 at the Zr K-edge
C. Laulhe, F. Hippert, J. Kreisel +4
Extended X-ray absorption fine structure (EXAFS) experiments at the Zr K-edge were carried out on perovskite relaxor ferroelectrics BaTi(1-x)Zr(x)O3 (BTZ) (x = 0.25, 0.30, 0.35), a…
