Title : Atomic level understanding of nanomaterial’s functionality by means of advanced operando studies: towards more efficient CO2 hydrogenation catalysts
Summary: The utilization of CO2 as a feedstock to produce fuels contributes to the reduction of carbon emissions and helps to decrease our dependence on fossil fuels. The methanation CO2 (Sabatier reaction) combines chemical storage of renewable energy, together with greenhouse gas reutilization offering a high energy density product (CH4). Ni, Co and Ru supported on oxides appear as promising catalysts for this reaction but suffer from fast deactivation due to sintering and carbon deposition. Here we propose the development of an efficient catalyst by introducing a new concept of using metal-doped ceria nanoparticles. After undergone an exsolution treatment these materials combine both high dispersion of the active metal and its close proximity with the ceria support, which are key characteristics of efficient catalysts. The Post-doctoral will use a newly developed method to synthesize the nanoparticles and will optimize the pretreatment to obtain the highest catalytic performance. This effort requires deeper insights into the electronic and geometric structure of the active catalytic states and therefore the project takes advantage of the sophisticated experimental tools for operando characterization which are in disposal in ICPEES but also in the collaborating German Institute (Berlin). The aim is to provide an atomic-level understanding of aspects related to the surface chemistry of functional catalysts and accordingly tune their properties by appropriate modification routes.

Postdoctoral position on polymer chemistry for biobased and biodegradable systems for drug delivery
Description of the position
BioTeam (http://www.biodeg.NET) is a well-known, international research group (Team Leader: Prof. Luc Avérous) within the ICPEES (UMR CNRS 7515), University of Strasbourg - France (One of the Top World Universities - Ranking for chemistry), focused on experimental approaches to systems based on biodegradable and/or biobased polymers for environmental and biomedical applications.
This postdoctoral position is associated with an industrial project in connection with an international company on cosmetics, to develop biobased and biodegradable drug delivery systems (chemical synthesis of polymers, polymers characterization and process).
6 months internship (Master 2 / Projet de fin d'étude) on the synthesis of model colloidal suspensions by heterogeneous polymerization techniques
This work will be done in the Polymer Engineering Department of ICPEES, in the frame of the LatexDry Project, funded by the National Research Agency (ANR), whose main objective is to gain fundamental knowledge of the mechanisms involved in the drying of colloidal suspensions and the formation of thin films. Model polymer particles suspensions will be synthesized with defined diameters, glass transition temperature, as well as surface charges by using emulsion, miniemulsion or dispersion polymerization.
