Offre de thèse : Analytical Chemistry on micro-imaging of industrial and historical paints (Grenoble)

Logo ESRFLogo Rijksmuseum

The goal is to study short term and long term drying reactions, and notably reactivity between metallic catalysts and alkyd binders. Such a question is fundamental both for the conservation of master pieces but also for the development of industrial paints. The analyses will be mainly based on 2D micro-imaging techniques (in particular infrared and synchrotron-based X-ray analyses such as X-ray fluorescence and X-ray diffraction), performed at Grenoble (beamline ID21 mainly) and in the Netherlands (UVA, Rijksmuseum and AkzoNobel). This PhD work is a collaborative project between the European Synchrotron Radiation Facility (ESRF), AkzoNobel, Stichting het Rijksmuseum and University of Amsterdam.
The work will require developing and implementing efficient analytical methodology, from sample preparation to data processing, for the 2D multi-modal micro-analysis of models and historical samples. The developed methodology will ultimately have outcomes both for museums (better knowledge of the historical use of driers) as well as for paint industries (for the design of new paints with better health and safety profile and improved performance).
