Missions

The determination of the structural and textural properties of porous materials is essential for the optimization of their properties. The structural evolution and the study of transport in these structures require a thorough study of their structural and textural properties in three dimensions, information that can be obtained by a combination of electron and x-ray tomography. In this context, a 3D analysis methodology must be set up to be able to compare, from a structural point of view and in a quantitative way, the different samples which are studied in parallel by other complementary techniques, in particular NMR. The postdoctoral researcher (M/F) will oversee the implementation of this methodology, from the acquisition of 3D data to their quantification, and of its application to all the systems of interest.

Activities

- Use a transmission electron microscope equipped with a corrected electronic probe.
- Develop methodologies for 3D imaging by electron tomography of the porous materials.
- Apply these methodologies to the study of the 3D architecture of nanostructured boehmite, mesoporous zeolites and clay-based systems
- Exploit data obtained by electron tomography and other 3D imaging techniques.
- Write scientific articles based on the results obtained and present the results at conferences.
- Participate in other scientific projects of the CARMEN laboratory
- Participate in the supervision of PhD students and trainees of the team.

Skills

- Strong expertise in the use of electron microscopy in material science.
- Know-how in the use of electron tomography
- Know-how in the use of other modes based on electron microscopy: EDX spectroscopy and electron diffraction.
- Knowledge in materials sciences and nanosciences, structural and chemical properties of condensed matter.
- Notions of heterogeneous catalysis.

Work Context

The scientist (M/F) will belong to the electronic microscopy team of the Surfaces and Interfaces department of the Institute of Physics and Chemistry of Materials of Strasbourg (IPCMS) and will use the equipment of the corresponding electronic microscopy platform. The team currently consists of a professor, three engineers and five doctoral students. This work is part of the research activities of the CARMEN Joint Research Laboratory and will take place at the IPCMS in Strasbourg with a few stays at IFPEN (IFP New Energy located in Lyon). Once developed, the methodology will then be applied to the other systems studied in the four theses currently underway in the joint laboratory, for which the 3D imaging tool represents the transversal subject between its various scientific axes.
The candidate (M/F)will also be able to develop other research topics around the use of electron microscopy to determine the equilibrium and dynamical structural properties of nanomaterials and nanostructures.
