Our Research Activities

Our research activities are focused on one side on the elaboration of thin film materials using electrochemical techniques, electro-assisted methods, or plasma techniques, and on the other side, on the characterisation of these synthesized materials in view of targeted applications such as energy, environment or health.

 

 Operation 1 : Corrosion and scaling, mechanism and inhibition

 

Participants : F. Arefi-Khonsari, H. Cheap-Charpentier, C. Debiemme-Chouvy, J. Han, A. Pailleret, J. Pulpytel

Goal : Understand corrosion and scaling mechanisms, and their inhibition by molecular or inorganic compounds, whether they are solubilised or immobilized.

Main tools : SQCM, Electrochemical Atomic Force Microscopy (EC-AFM), electrochemical impedance spectroscopy (EIS), atomic emission spectroelectrochemistry (AESEC)

                                                                     

Collaborations : TotalEnergie, Safran, ICMT (Ohio Univ., USA), SEB-CALOR, LCMCP-SU, VEOLIA, SIAAP, ISSTE-Tunisie, Western Ontario University (Canada), McMaster University (Canada), Institut de Recherche de Chimie ParisTech (IRCP), CEA Saclay
