Missions

The solid-state NMR group of the University of Aix Marseille is looking for motivated candidates for a postdoctoral research position in chemical sciences funded by the European Research Council (ERC). The project aims to develop and apply an emerging NMR hyperpolarization technique, MAS-DNP (nuclear dynamic polarization under magic-angle spinning). This approach is used to increase the sensitivity of solid-state nuclear magnetic resonance (SSNMR), allowing the extraction of unique structural information on solid materials at the atomic scale without requiring isotopic enrichment.

Activities

The aim of the project is to develop a new experimental approach to study the structure and the formation of organic solids. These materials, essentially composed of small organic molecules, can assume different crystallize forms, a phenomenon known as polymorphism, whose physical origins are not yet fully understood.

The postdoctoral researcher recruited as part of this project will:

• develop new NMR experiments for the structural study of organic powders by hyperpolarized NMR (MAS DNP)

• develop new tools to increase the temporal resolution of the analysis of crystallizing systems by DNP NMR.

Skills

Applicants must have a PhD in physical or physical-chemistry sciences and a previous experience in NMR.

Work Context

Host Institution - Research carried out under this project will be conducted at the Institut de Chimie Radicalaire (ICR, UMR7273). 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 whose fields vary from 300 to 600 MHz. In particular, the laboratory is equipped with a new 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 postdoctoral position is funded by the CNRS initially for one year, renewable up to 2.5 years depending on the results. Salary depends on experience (2200 € - 3100 € net / month). 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.
