At CNRS, within the laboratory ICMN, the research engineer activities will be part of the « Functional Carbons - Environment - Biomaterials » team. It is in charge of developing researches focused on functionalized and nanostructured carbon materials, on the study of their physico-chemical, textural and structural properties and on their interfacial reactivity.
In ICMN laboratory, the research engineer on fixed term contract will work under the supervision of an Assistant professor, within the project DEPRICAME financed by “Région Centre-Val de Loire”, « DEcap/PRIme: PIVOTS platforms for specific activated carbons for MEtolachlor and its metabolites». The objective of the project is to elaborate and eventually to functionalize activated carbons from lignocellulosic raw materials (agriculture residues of the Region) to optimize the kinetics and the adsorption capacities of removal of metolachlor and its metabolites. A technical validation (tests in an experimental scale pilot of the PRIME platform with contaminated natural waters) will be carried out at the end of the project.
The research engineer will contribute to develop activities such as:
• design and develop technology for activated carbons development by physical and/or chemical activations from different lignocellulosic raw materials by studying the biochemical composition in hemicelluloses, cellulose and lignin,
• develop, adapt and coordinate textural, microtextural and structural characteristics and chemical surface composition of the elaborated and modified materials,
• establishment and optimization of surface functionalization methods in order to modify in a controlled way the physical-chemical characteristics of the carbonaceous materials developed (porosity, surface chemistry),
• Textural (N2 adsorption), microtextural and structural (MET) characteristics and chemical composition (SEM-EDX, IRTF, XPS,..) of the elaborated and modified carbonaceous materials,
• study and optimization of kinetics and isotherm of adsorption of metolachlor and its derivatives on activated carbons developed and modified to understand the adsorption mechanism for extrapolation of the process at the metric scale
• test of the optimized activated carbons in metric scale dynamic.
• study, development and management of HPLC analysis of this kind of molecules,
• optimization of adsorption capacities of carbonaceous materials,
• promote results through publication of articles in international journal on the results of the data collected during the project,
• participation to workshops and conferences,
• valorization of the project: actions to make science accessible (“Fête de la science”...)
It is expected that the data obtained will be part of the final report of the project DEPRICAME financed by “Région Centre-Val de Loire” “DEcap/PRIme: PIVOTS platforms for specific activated carbons for MEtolachlor and its metabolites”.
The candidate will have to work on his own and is expected to have:
• recent thesis (<2ans) in material science, specializing in material physico-chemistry;
• strong skills in materials science, sound knowledge in physico-chemistry of carbon materials and ideally with experience in the field of functionalization;
• skill in research attested by, at least, one paper as first author or second author in topics in relation to the activities of the project;
• very positive attitude for working in a team, on a pluridisciplinary project (material science, HPLC analysis);
• organisational ability and ability to learn and develop one's skills;
• fluent French and English, written and spoken;.
• abilities to coach a master student.
ICMN research unit (UMR 7374, Orléans, France) belongs to CNRS (unit of the Physic Institute) and the University of Orléans. With 47 agents including 34 permanent staff, the laboratory is located on CNRS campus. The scientific goals of the ICMN are based on multi-scale and pluridisciplinary approaches of materials, nanoscopic objects and systems, in combining experimental and numerical simulation studies. Our activities are focused on the understanding of the multi-scale organization of the nanometric elementary units, of their mutual interactions, and of the phenomenon occurring at interfaces in the materials and systems studied. This approach enables a better identification and understanding of the physico-chemical phenomena responsible for the behavior of materials, allowing to improve and to optimize the requested properties. The characterization of the structure, microtexture, multiscale organization, and chemistry of materials is based on an instrumental park having a wide range of analytical techniques, powerful in material science (see description of the techniques on the ICMN website).
Constraints and risks
• Short periods of travel (1 or 2 weeks) within France should be expected.
• A training in HPLC analysis is an additional.
