Activités de recherche

Since December 2012CNRS Research fellow (CR2) in inorganic chemistry at ICSM
Focused on the study of the chemical durability of the spent nuclear fuel and the conditioning matrices from the reprocessing to the final storage
  • Synthesized and characterized actinide (Th, U) silicate-, oxide-, and phosphate-based compounds,
  • Performed sintering and dissolution/leaching experiments.
November 2011 – December 2012Postdoctoral researcher in the Prof. Ibers Research Group (Northwestern University, USA)
  • Performed exploratory high-temperature solid-state synthesis of actinide chalcogenide materials,
  • Determined structures via single crystal X-ray diffraction,
  • Measured magnetic, optical, and electronic properties.
November 2010 – October 2011Researcher scientist at ICSM
  • Performed multi-parametric studies of the dissolution of lanthanide and actinide oxides.

Compétences en Chimie inorganique

  • Actinide based materials:
    Elaboration, sintering and chemical durability (dissolution) of oxides, silicates, phosphates and chalcogenides
  • Radioactive waste management:
    Conditioning in cementitious matrices, hydration, characterization, solid/solution interaction
  • Metal Organic Frameworks (MOF’s):
    Syntheses in aqueous solution "soft chemistry", structural and physical properties characterizations
  • Crystallography:
    Strong skills in powder and single-crystal diffraction (X-ray and neutron)

 

Techniques
