Advanced Characterization

The methodological axes of the team in connection with MaTerRe are :

  • Studies of structure/property relationships by X-ray diffraction (XRD) of :
    • materials with potential storage properties (e.g. zeolites)
    • molecular complexes or materials with remarkable properties controlled by pressure or temperature stimuli (spin transition, charge transfer, mechanochromism, polymerization, …)
    • nano-objects or objects in the early stages of nucleation using the pair distribution function approach
  • In situ structural studies by XRD under controlled pressure, temperature and atmosphere of micro-quantities (0.005mm3).
  • Combined microdiffraction / X-ray microfluorescence approach.
  • Continuity of experiments with Synchrotrons: management of a BAG (Block Allocation Group) on the CRISTAL beamline of SOLEIL synchrotron.
  • Structural and chemical study of nanomaterials by (scanning) transmission electron microscopy (S)TEM and by electron energy loss spectroscopy (EELS), especially at ultra-high energy resolution with the acquisition of a rare instrument: NION HERMES 200keV SX (available at the end of 2024). Development of new instrumentation and experimental methods relying on EELS.

Platforms and equipment

  • X-ray Diffraction platform accredited by Sorbonne University and open to the whole community.
  • PANAM microscope of PANAM GdS (Sorbonne Université/CNRS/Université Paris Cité) – NION HERMES 200keV SX (available at the end of 2024)
