Missions

A CNRS post-doctoral research position funded by the European Research Council (ERC) is available in the RMN DNP group of the Institut de Chimie Radicalaire in Marseille, France.
The overall objective of the project is to develop and apply an emerging NMR hyperpolarization technique, namely Magic Angle Rotational Nuclear Dynamic Polarization (MAS-DNP), for the structural characterization of polymorphic molecular materials existing as powders at natural isotopic abundance.

Activities

The main challenge will consist in getting short and long-range quantitative structural parameters to be interpreted in terms of molecular conformational properties or supramolecular packing, helping unravel the atomic-level solid structure of molecular materials. For this, the candidate will actively work on the development of new NMR pulse sequences suitable for acquisition under MAS DNP conditions for the measurement of NMR observables such as dipolar and/or scalar coupling.

The research project will focus more specifically on the following aspects:
-development and optimization of robust pulse sequences for measuring dipolar and / or scalar couplings between rare ½ spin nuclei with natural isotopic abundance
-the translation of these experiments to the observation of relevant quadrupole nuclei
-application of the methods developed to the characterization of polymorphic molecular materials

Skills

This offer is open to candidates with a training in physical chemistry or materials chemistry, and a PhD involving solid state NMR. Previous experience with NMR pulse sequences is an asset. The ideal candidate is expected to be curious and motivated, capable of working on an interdisciplinary project, and should have excellent communication skills (both oral and written), notably in English.

Work Context

The project will take place at the Institut de Chimie Radicalaire de Marseille (ICR, UMR 7273, https://icr.univ-amu.fr/en/), within the solid-state DNP NMR research group. Located in the south of France in Marseille, the ICR is internationally recognized for its double expertise in i) the development of new DNP approaches for the characterization of organic solids and ii) the synthesis of radical species currently used as polarizing agents the most effective for the analysis of solids via MAS DNP. The laboratory has free access to high performance computing facilities through the Mesocentre of Aix-Marseille Université. With the Spectropole analytical facility on-site, ICR has access to a wide range of instruments for material analysis, and several NMR spectrometers for liquids and solids with magnetic fields ranging between 300 and 600 MHz. In particular, the laboratory is equipped with a 400 MHz MAS-DNP spectrometer as well as with a 400 MHz wide bore NMR spectrometer with numerous MAS probes up to 60 kHz.
The selected candidate will interact on a day-to-day basis with a team of researchers and students and also with scientists with whom the team has established collaborations, both nationally and internationally.

The expected starting date is between January 2022 and March 2022.
The postdoctoral position is funded by the CNRS initially for one year, renewable depending on the results. Applications will be considered on a rolling basis.
The CNRS is labeled HR Excellence for Research (HRS4R) and promotes the transparency of the recruitment process and equal opportunities.
