Implementation of a software package for the simulation of the Infrared Thermography Non Destructive Testing method
The CEA LIST implements simulation tools for several Non Destructively Testing (NDT) techniques, integrated to the CIVA software platform. The different methods used, nowadays in the CIVA platform, concern the ultrasonics, eddy current and radiography techniques. The TREFLE is a reference lab in thermics and had developped some original modelling approachs for the control by Infrared Thermography (IR) method. In the frame of a project funded by the Aquitaine region, these two labs collabore to implement simulation tools for the NDT by the Infrared Thermography technique, dedicated to industrial applications and accesssible to a non-numericians public.
The objective of this post-doc position is the implementation of physical modelling (in a matlab environment) for the resolution of transient thermal problems in multilayers configurations (like composite materials used in aeronautics), eventually anisotropic, for a flash or a periodic excitation with uniform or point irradtiation.
Optimization of Li metal/electrolyte for the next generation of all-solid-state battery
CEA Tech Nouvelle-Aquitaine, created in 2013, set up a new laboratory, since more than two years, focused on both the development of materials and the high throughput screening to accelerate the discovery of materials for the next generations of Li-ion batteries. For that, the CEA Tech Nouvelle-Aquitaine acquires different vacuum deposition equipment (sputtering, evaporation, atomic layer deposition) integrated in glovebox and different automated characterization techniques (SEM-EDX, profilometer, XRD, LIBS and confocal microscope later).
The Li metal/electrolyte interface constitutes one of the main challenges to overcome for the next generation of all-solid-state battery. The reactions of decompositions at the interface associated to uneven plating/stripping of Li ions lead to quick cell failure. One of the avenue for stabilizing it is to use a protective layer, which must feature numerous physical-chemical properties. In this context, this internal CEA project aims at setting up a combinatorial synthesis methodology associated to high throughput characterizations in order to accelerate the discovery of new protective layers at the Li metal/electrolyte interface.
We are seeking for an outstanding applicant who will be in charge of setting up the whole methodology, from the synthesis to the physical-chemical-electrochemical characterizations of the materials. She/he will have at her disposal a new state-of-the-art infrastructures. She/he will collaborate with other CEA labs located at LITEN (Grenoble, France).
