On the Origin of the Green Colour of Archaeological Bone Artefacts of the Gallo-Roman Period

Autor: Ginette Auxiette, F. Farges, Thierry Allard, Sylvain Pont, Patrick Cordier, Gilles Catillon, Ph. Rollet, J. Ferrand, Stéphanie Rossano

Publikováno v: Archaeometry. 56:1024-1040

Recent findings in the city of Reims have lead to the discovery of manufactured bone objects coloured in green throughout their entire volume. In order to discover the intentional nature of the colouration and to propose a colouration mechanism, mode

Alexithymie et toxicomanie : lien avec la dépression

Autor: Gwenolé Loas, Martine F. Flament, Jean-Luc Venisse, F. Farges, Maurice Corcos, P. Jeammet, Paul Bizouard, Olivier Halfon, Mario Speranza, F. Lang, Fernando Perez-Diaz

Publikováno v: L'Encéphale. 30:201-211

Resume L’hypothese principale de cette etude est de confirmer la prevalence elevee de l’alexithymie chez les toxicomanes en verifiant son independance par rapport aux variables sociodemographiques (sexe, âge, categorie socioprofessionnelle). Dan

Ti K-Edge XANES Studies of Oxides: Theory vs. Experiment

Autor: John J. Rehr, F. Farges, Gordon E. Brown

Publikováno v: Le Journal de Physique IV. 7:C2-191

Ti K-edge x-ray absorption near edge structure (XANES) spectra for a variety of Ti(IV)-bearing crystalline oxide model compounds have been measured and compared to ab-initio multiple-scattering XANES calculations using the FEFF6 code. Depending on Ti

Local environment around gold (III) in aqueous chloride solutions: An EXAFS spectroscopy study

Autor: Gordon E. Brown, Julia A. Sharps, F. Farges

Publikováno v: Geochimica et Cosmochimica Acta. 57:1243-1252

The local environment around Au (III) in aqueous solutions containing 1 M NaCl was determined as a function of pH and Au concentration using X-ray absorption spectroscopy (XAS) at ambient temperature and pressure. The solution Au concentrations studi

Structural environments of incompatible elements in silicate glass/melt systems: II. UIV, UV, and UVI

Autor: Georges Calas, Carl W. Ponader, F. Farges, Gordon E. Brown

Publikováno v: Geochimica et Cosmochimica Acta. 56:4205-4220

The structural environments of trace to minor levels (≈2000 ppm to ≈3.0 wt%) of U in several silicate glasses were examined as a function of oxygen fugacity, melt composition, and melt polymerization using X-ray (XANES and EXAFS) and optical abso
