Without being focused on a particular route of synthesis, material type or focused area of applications, the activities of our team have in common the control of structures at the nanoscale. For this, they rely on the skills of chemists including solid state chemistry, inorganic synthesis in solution, surface grafting of molecular species and organic polymerization in dispersed media.
Whether metal, metal oxide, multiphase or hybrid nanomaterials are concerned, our field of investigation is the control of chemical composition, defects and surface features of (nano)particles up to their assembly with a particular effort focused on the control of surfaces, interfaces and morphologies. A summary of our skills in 10 points is presented below:
1. Control of particle size
2. Relationship between crystalline structure and chemical composition
3. Selectivity of surface crystallographic planes / control of particle shape
4. Introduction of surface defects
5. Study of the phenomena of nucleation/growth of supported particles
6. Plasticity at interfaces
7. Control of surface charges
8. Continuous or discontinuous encapsulation in a second phase
9. Surface grafting of molecules / Arrangement into continuous films or patches
10. Assemblage par interactions contrôlées ou par frittage / Arrangement en clusters discrets ou en réseaux étendus
The targeted applications are in the areas of optics, catalysis, health and sustainable development.
