• A complete mastering of the synthesis, at the industrial level : SiO2, CeO2, rare earth oxides and salts, 2D Zirconium Phosphates (alpha ZrP), ..
• The control of particles sizes : 5 - 25 - 50 - 100 nm ...
• Formulation : aqueous or organic suspensions, high concentrations up to 400 g.L-1 in CeO2 e. g., agglomerated powders (< 100 nm)
• Functionalisation and surface chemistry (ex. hydrophilic/hydrophobic) : inorganic encapsulation, grafting/adsorption of organic molecules
• Structuration of nanoparticles (mesoporous or anisotropic structures)
• Modelisation of optical effects (transparency, opaqueness, brightness, colour)

The knowledge of the behaviour of nanoparticles in the application medium and the capacity to formulate « ready-to-use » systems, by adjusting surface chemistry (affinity with substrate, dispersibility, agglomeration control, …)
