Clémence Iacconi

Project: Photochemistry of Prussian blue - Zinc white mixtures in oil paintings by chemical imaging and synchrotron techniques. Influence of light wavelength on the photoreduction of Prussian blue in cyanotypes.

Clémence received her master in Chemistry at the École polytechnique de Lausanne under my supervision and in collaboration with Prof. Jacques-Edouard Moser. During her master, she investigated the photochemistry of Prussian blue / Zinc white mixtures in oil paintings. By using a combination of X-ray absorption spectroscopy at the Fe and Zn-edge, synchrotron microphotoluminescence and Raman spectroscopy, she could highlight the main mechanisms responsible for the photodegradation of the paint system. She is now still involved in deciphering the photochemistry of Prussian blue, however in another type of systems, namely in photographic prints called cyanotypes.
