Journal ArticleDOI
Probing the structure of heterogeneous diluted materials by diffraction tomography.
TL;DR: The potential of coupling pencil-beam tomography with X-ray diffraction to examine unidentified phases in nanomaterials and polycrystalline materials is shown, enabling a multimodal analysis of prime importance in materials science, chemistry, geology, environmental science, medical science, palaeontology and cultural heritage.
Journal ArticleDOI
Early use of PbS nanotechnology for an ancient hair dyeing formula.
Philippe Walter,Eleonore Welcomme,Philippe Hallégot,Nestor J. Zaluzec,Christopher Deeb,Jacques Castaing,Patrick Veyssiere,René Breniaux,Jean-Luc Leveque,G. Tsoucaris +9 more
TL;DR: It is remarkable that the composition and supramolecular organization of keratins can control PbS nanocrystal growth inside a hair during blackening.
Journal ArticleDOI
Classification of lead white pigments using synchrotron radiation micro X-ray diffraction
Eleonore Welcomme,Philippe Walter,Pierre Bleuet,Jean-Louis Hodeau,Eric Dooryhee,Pauline Martinetto,Michel Menu +6 more
TL;DR: In this paper, the results achieved on several paint samples taken from Matthias Grunewald's works were described, in reflection and transmission modes, directly on minute samples or on paint cross-sections embedded in resin.
Journal ArticleDOI
Synchrotron-based X-ray spectromicroscopy used for the study of an atypical micrometric pigment in 16th century paintings.
Marine Cotte,Eleonore Welcomme,Vicente A. Solé,Murielle Salomé,M. Menu,P. Walter,Jean Susini +6 more
TL;DR: The analysis of materials used to render a metallic aspect in the Isenhein Altarpiece and the Basel's Crucifixion is presented, illustrating developments of synchrotron X-ray microprobe methods for the chemical characterization and observation of complex and micrometer-scale materials.
Journal ArticleDOI
Investigation of white pigments used as make-up during the Greco-Roman period
TL;DR: In this paper, the mineralogical composition of cosmetics, the trace element content and the microstructure of the crystals were determined by combining observations and elemental analysis with structural information, which enabled them to describe the choice of materials and their preparation by grinding or chemical synthesis.
