The understanding of fossilization mechanisms at the nanoscale remains extremely challenging despite its fundamental interest and its implications for paleontology, archaeology, geoscience, and environmental and material sciences. The mineralization mechanism by which c...

The in situ two-dimensional (2D) and 3D imaging of the chemical speciation of organic fossils is an unsolved problem in paleontology and cultural heritage. Here, we use x-ray Raman scattering (XRS)–based imaging at the carbon K-edge to form 2D and 3D images of the carbo...

International audience; We provide in this study a new application of laser-induced breakdown spectroscopy (LIBS) to evaluate whether ancient bones contain sufficient organic material before radiocarbon dating, which can avoid a complex preliminary analysis on the sampl...

International audience; The detailed description of corrosion processes in ancient and historical metal artifacts currently relies on the in-depth study of prepared cross sections. The in-plane elemental and phase distributions can be established from a combination of l...

International audience; The process of mimicking properties of specific interest (such as mechanical, optical, and structural) observed in ancient and historical systems is designated here as paleo-inspiration. For instance, recovery in archae- ology or paleontology ide...

This Scientific Vision aims to monitor the landscape of the setting up of the E-RIHS infrastructure, to describe the main scientific ambitions of E-RIHS in the coming years and to outline what pathways will be used to achieve them.The E-RIHS Scientific Vision will be th...

Application of a protective coating is the most widely used conservation treatment for outdoor bronzes (cast Cu-Sn-Zn-Pb-Sb alloys). However, improving coating protectiveness requires detailed knowledge of the coating/substrate chemical bonding. This is particularly the...

Abstract The aim of this research project was the development of a hybrid system in laboratory coupling together three analytical techniques, namely laser-induced breakdown spectroscopy (LIBS), laser-induced fluorescence (LIF) and Raman spectroscopy in a single instrume...

International audience; Access to high quality Cultural Heritage data and metadata is the condition for reliable, performant and verifiable research in many arts and humanities fields. One of the core challenges of giving access to Cultural Heritage data is often the la...

[EN] The Château de Germolles is one of the rare palace in France dating from the 14th century. The noble floor is decorated with wall paintings that are a unique example of courtly love spirit that infused the princely courts of the time. After being concealed sometime...
