INAC (Institute for Nanoscience and Cryogenics, CEA Grenoble) has a PhD opening for a physical chemist. This position will deal with the development and application of a new and emerging technique: high magnetic field MAS-DNP (Magic Angle Spinning Dynamic Nuclear Polarization). This powerful tool is used to hyperpolarize nuclei such that high-sensitivity and high-resolution solid-state NMR (Nuclear Magnetic Resonance) spectra can be obtained and used to extract important structural information at the atomic-scale, such as surface functionalization and internuclear distances (see ref. 1), as well as crystallographic data (see ref. 2).
Since the potential of this technique is beginning to be realized (see ref. 3), the aim of this PhD will be to further develop the methodology to apply it to study materials of significant importance for the future of “greener” energy, which could not have been otherwise investigated in such a manner. The studied materials will arise from diverse but related fields including heterogeneous catalysis, fuel cells, photovoltaics, and nuclear wastes.
This PhD will take place in the highly dynamical environment of the MINATEC campus (CEA Grenoble) and more specifically in the nanocharacterization platform (PFNC) where the DNP group, in collaboration with Bruker Biospin (world leader in DNP and NMR instrumentation), is currently pushing the development and use of MAS-DNP beyond its current state-of-the-art. The group is working with the first high-field MAS-DNP system installed in France (since September 2011) and has successfully conducted instrumental and methodological developments over the last three years (a selection of which are given in the references).
Overall, we aim to demonstrate that with the several orders of magnitude of sensitivity gain achievable with MAS-DNP, solid-state NMR has the potential to address crucial problems for systems where other well-established spectroscopies (X-ray analysis, solution-state NMR, etc.) cannot be applied successfully.
This PhD will take place involving strong partnerships with different academic laboratories within CEA and INAC (SCIB and SPRAM) as well as CEA/ICSM and industrial partners (such as Bruker Biospin).
