Typical job: Research engineer in materials science / characterization
Missions
Develop advanced transmission electron microscopy characterization techniques at the nanometric scale (e.g. 4D-STEM, EDS and EELS hyperspectral spectroscopies, DPC, ptychography, STEM-HAADF tomography, EELS tomography, etc.), with attention paid to sensitive materials.
Activities
– Implement and develop the use of advanced techniques in electron microscopy.
– Implementation of data acquisition procedures adapted to sensitive materials.
– Implementation of data acquisition and processing procedures adapted to weak signals (4D-STEM or EDX and EELS hyperspectral data).
– Possible applications to the studies of a wide range of materials (zeolites, minerals, MOF, COF, biomaterials, etc.), in interaction with platform users (approximately 30% of the time).
– Processing of massive data and formatting of results (expert reports, publications, etc.).
SKILLS
– Strong skills in corrected MET.
– Ability to implement original methodological developments.
– Experience in the study of micro and nanostructures.
– Experience in processing massive data.
– Ability to work independently.
– Ability to work in an interdisciplinary and multinational context.
Work context
The position is funded by the CPER CHEMACT project, with FEDER funds. The recruited person will be integrated into the Chevreul Institute (FR 2638). This institute manages the advanced characterization platform, including an electron microscopy center. This center includes 3 SEMs and 2 TEMs. One of the TEMs is probe-corrected (TITAN THEMIS 300kV). The other microscope will soon be replaced by a JEOL FEG 200kV microscope optimized for 4D-STEM work. These two microscopes are equipped with direct electron detection cameras. The recruited person will be responsible for developing work on these microscopes. They will work in close collaboration with two research engineers assigned to the microscopy center and with researchers heavily involved in the study of materials at the nanoscale.
In recent years, the electron microscopy center has made developments in the study of sensitive materials. The objective of this recruitment is to consolidate and extend these developments, as well as to conduct work to apply them to study objects. The TITAN microscope is equipped with hybrid electron detectors and segmented detectors as well as monochromation used for EELS work. The flexibility of 4D-STEM and the different image reconstruction strategies have been developed for the study of zeolites, MOF structures, 2D materials and clays. The center wishes to emphasize developments adapted to high-resolution imaging in low dose to sensitive materials as well as tomography adapted to the study of nano-porosities in natural and synthetic materials.
The Chevreul Institute is a research federation in the field of “Chemistry-Materials”, with a perimeter of approximately 500 people. The electron microscopy center is located within the central building of the Institute. This center is composed of 5 engineers and is used by several dozen researchers. The Villeneuve d’Ascq science campus has an on-site university restaurant and easy access by public transport.
