Research activities

Main research topic : chemistry and nucleation & growth in high pressure/high temperature fluids, mainly supercritical fluids, with the development of the associated technologies, for the design and recycling of advanced nanostructured materials.
1) Chemistry driven approach for the synthesis of targeted materials : study of the transformation of metal precursors (home made or commercially available) in different types of near- and supercritical solvents : carbon dioxide, water, alcohols, ammonia, …, and mixture of them. Access to high quality nanostructures (pure phases with high crystallinity) with controlled composition and physico-chemical properties , among the families of metals, metal oxides, oxyhydroxides, nitrides, sulfides and selenides.
2) Development of continuous one pot multi-step processes for advanced materials by design. Association in series or in parallel of near- and supercritical reactors (micro- to millifluidic reactors) to obtain core-shell architectures, supported nanoparticles, tetrapods, in other words, to go towards multifunctional advanced materials.
3) Switch from conventional hydrothermal/solvothermal synthesis (batch mode, from few hours to days) to near- and supercritical hydrothermal/solvothermal synthesis (few tens of seconds) through the increase of kinetics and the use of a continuous process. Access to a new generation of synthetic materials–based on geominerals and metastable phases in the synthesis conditions.
4) Development of recycling technologies of materials-based on the use of near- and supercritical fluids, mainly carbon dioxide, water and water / alcohol mixtures. Recycling of carbon fibers from composites, recycling of aramide and natural fibers from composites, recycling of permanent magnets, recycling of solar cells and delamination of multimaterials.
