Missions

the first objective of the postdoc is to develop a protocol for the nanoscale characterisation of plasma nanocomposites in order to establish relationships between nanostructure and properties as a function of abiotic and biotic production mechanisms, discharge conditions and precursor nanomaterials. This protocol will be developed in partnership with the development of the plasma nanocomposite database piloted by Marie-Agnès Courty (PROMES) on the basis of meso and microscale characterisation (optical microscopy and SEM).

Activities

The postdoc will have mastery of the operating techniques to be implemented for a characterisation in transmission electron microscopy (TEM) of the nanoscale at the atomic level. He will develop a comparative characterisation protocol to identify specific properties and nanostructures of the three types of polymer nanocomposites studied:
- those produced in the atmosphere by plasma discharges;
- those traced in the products of the hive (supposedly produced by ultrasonolysis);
- those synthesised in the laboratory under controlled conditions by electric discharges in a liquid medium and ultrasonolysis.

The postdoc will be involved in the development of experimental protocols and protocols for the physical, chemical, molecular, spectroscopic and isotopic analysis of plasma nanocomposites. In close collaboration with the partners of part 1 (PROMES, ChimEco, ICSM), the postdoc will co-pilot all the multianalytical characterisation data of plasma nanocomposites to produce synthesis documents in stages, with a view to their publication.

The postdoc will be strongly encouraged to use high-performance sample preparation techniques for high-resolution characterisation of plasma nanocomposites, in particular by FIB (Focused Ion Beam Experiments). He will master STEM-EELS, STEM-X-EDXS and high resolution X-ray crystallography for the characterization of nanoelements in 2D. In particular, he will develop electron tomography techniques for the 3D reconstruction of plasma nanocomposites with sub-nanometer resolution.
The postdoc will focus on the impact of ionising radiation on nanomaterials with a view to identifying these effects on the properties of plasma nanocomposites. This exploration will help the partners of part 1 of the LINA project to develop experimental protocols to test the hypothesis of the emission of neutron fluxes by plasma discharges in the presence of deuterated biomaterials.

Skills

The candidate should have the following skills and be able to work independently:
- Skills in transmission electron microscopy, material sciences, plasma physics and nuclear physics.
- A keen interest in interdisciplinarity and the development of innovative methods at the interface of material physics, chemistry, geosciences and environmental sciences.
- An excellent spirit of synthesis and an interest in 3D dynamic simulation to facilitate communication on plasma nanocomposites to a wide audience.
