MORPHology and structure of nanomatErials stUdied by X-ray Scattering

This platform of X-ray scattering experiments within the MATRIX team is well-adapted to the study of nanostructured materials (nanoparticles, nanoobjects, nano- and meso-porous materials, liquid crystals, composites, biomaterials, polymers, etc). The MORPHEUS platform allows the structural characterization of objects over a wide range of sizes to determine their morphology, crystallinity or organization. The techniques implemented on the platform are :

  • Small-angle (SAXS-Cu (with Cu radiation), SAXS-Mo (Mo radiation), GISAXS) and wide-angle (WAXS-Cu, WAXS-Mo) X-ray scattering
  • Microdiffraction
  • X-ray fluorescence
  • High-energy powder diffraction associated with PDF analysis

The 8 experiments of the platform are complementary and cover a wide wide range of q scattering wavevectors.

Range of scattering wavevectors q and corresponding size d domains accessible on the MORPHEUS platform.

Measurements and analysis can be performed on isotropic samples (powders, suspensions), but also on oriented samples (fibers, films, membranes …) to study anisotropy or preferential orientation at different scales, thanks to the expertise of MATRIX team. Various conditions are also available (temperatures, controlled humidity, magnetic and electric fields, …).

Examples: a) Fe2O3 nanoparticles aligned in a magnetic field [1], b) cobalt supracrystals [2], c) hydration of a graphene oxide film [3], d) fiber of imogolite nanotube [4].

The platform is open to external teams and laboratories through:

  • Scientific collaborative projects.
  • Services including: user formation and support, measurements and data analysis, experimental reports.
