Molecules and Materials Engineering

Thanks to its expertise in solution synthesis, the team is working on the elucidation of the crystal growth mechanisms of granular homo- and/or hetero-nanostructures in order to better control their morphology. It also works on surface modification to prepare mono- or multifunctional nanohybrids. In parallel, on these synthesized, modified or even recycled (from urban mines) nano-objects, the team develops original experimental approaches of shaping in order to exalt their properties without losing their nanostructure (surface polymerization, colloidal chemistry, sintering by Spark Plasma Sintering, 3D/2D printing, sol-gel assisted by deep UV photo-sintering). Once shaped, they are then integrated into advanced devices such as sensors, embedded energy generators, bioimplants, antibacterial drugs, nanoprobes for magnetic and/or optical medical imaging, ultrafine capacitive electroluminescent devices, high density granular magnetic recording media, solid state photoelectrochemical cells, magnetic motors, catalytic printed reactors, magnetic refrigerants, among others.
