Missions

The postdoctoral fellow will join the Biosourced Materials team of the Jean Lamour Institute. He or she will work under the responsibility of Vanessa Fierro (DR CNRS) in the frame of the UCGWATER+ (Coal- and bio-based water remediation strategies for underground coal gasification and beyond) project funded by the RFCS. In UCGWATER+, the use of Friedel–Crafts chemistry will be explored to form abundant linkages between the molecular components of coal tar products to afford novel highly crosslinked polymer networks and carbon materials with high yields. Hypercrosslinked polymers (HCPs) are high surface area materials boasting permanent micropores (pore size <2 nm), which can be directly used for adsorption applications. These materials will be used for UCG water remediation.

Activities

The researcher will prepare hyper-crosslinked polymeric materials by different methods (Friedel-Crafts reaction, among others) and carbonaceous materials for which he/she will be in charge of the complete characterization. Based on the results obtained, the candidate will have to propose modifications to the synthesis conditions and optimize them to improve the adsorption performance of the materials. The work will therefore consist of a thorough knowledge of the state of the art in the field in order to improve the latest results in the literature and to apply them, after the necessary adaptations, to the precursors used in the UCGWATER+ project. He/she will be expected to write the scientific reports and publications associated with his/her work and to present his/her research work at national and international conferences and meetings.

Skills

The candidate should have a PhD in science, specialising in materials, or chemical engineering or industrial chemistry, with a good knowledge of polymer and carbon science, experience in writing international publications and a background combining knowledge of porous materials and adsorption. Other essential criteria for this position are responsiveness and autonomy in the laboratory as well as the ability to work in a team, and an excellent knowledge of the techniques available: polymer synthesis and pyrolysis, density and porosity measurements, structural and chemical analyses, electron microscopy, Raman spectrometry, etc. The candidate must also be able to write A-level publications quickly and present his/her results at international conferences.

Work Context

The Institut Jean Lamour is a mixed research unit from the CNRS and the Université de Lorraine. Its activities are spread on 3 distinct sites: Nancy (Campus ARTEM, where most of teams are hosted), Epinal (Campus Bois, where the work will take place), and Metz (Campus Bridoux). It gathers around 550 people.
