Research themes

Fields of interest: crystallography, X-ray powder diffraction and reactivity of solids

- Elaboration of porous hybrid materials (PCPs, MOFs) based on metal polyhedra and metal-clusters using commercial or original ligands (luminescent, chiral ones) for environmental applications (molecules storage/selection, catalysis, sensors).

- Microstructural analysis of the materials: preparation of nanocrystalline materials (powders); understanding of the formation and nature of the defects within nanocrystalline solids (reticular distorsions, crystallite size, stacking faults); microstructural analysis of oxides and sulfides used as catalysts, semiconductors, electrode materials ....

 

Scientific responsabilities

- Member of the Scientific Committee of EPDIC (European Powder Diffraction Conference),

- Member of the Scientific Committee of the Conference Rayons X et Matière.

Technical skills

- synthesis of coordination polymers and MOFs through solvothermal synthesis routes and mechanochemistry.

- Structural analysis of the materials from single-crystals and powders: ab initio structure determination using methods operating in reciprocal space and in real space from single-crystal and powder XRD data; refinements of the structural models (Rietveld method).

- Microstructural analysis of the materials: preparation of nanocrystalline materials (powders); understanding of the formation and nature of the defects within nanocrystalline solids (reticular distorsions, crystallite size, stacking faults); microstructural analysis by line-profile analysis of X-ray powder diffraction patterns (integral-breadth method, Fourier analysis with writting of a software).

- Multi-scale analysis of materials: combination of diffraction (XRD) and spectroscopy (FPG NMR) techniques for the study of the diffusion of guest molecules in porous host structures
