CPER-FEDER project Multi3

Multi3 : Advanced multi-scale and multi-functional characterization for multi-disciplinary research

 

The importance of fine characterization techniques in laboratories specializing in the study of the physical, mechanical or chemical properties of materials in general is well established. In order to understand microstructure/property relationships, develop new materials and analyze synthesis or processing methods, it is essential to have high-performance analysis tools on a wide range of scales, from the micron to the atomic scale. In addition, as the materials and systems studied become increasingly complex, with several functions targeted simultaneously, it is also crucial to know the surface characteristics of the materials studied, to obtain a three-dimensional (3D) view of their structure, and to be able to study at the relevant scales the relationships between their structure and the targeted properties, under conditions that best reproduce the actual environment of use (so-called “operando” imaging).

The Lyon Saint-Etienne Consortium is a federative structure pooling advanced microscopy equipment, for academic research of excellence on multi-scale structure-property relationships, in particular via operando microscopy. The MULTI3 project aims to extend the range of 3D and operando characterization facilities available at CLYM.

 

Target equipments

  • a double-column ion microscope (FIB) equipped with analytical accessories (EDS, EBSD) and a cryogenic stage. The machine must be highly versatile, enabling users not only to prepare cross-sections and thin sections, but also to machine (large) parts and perform 3D analyses.
  • an in situ liquid-cell holder for transmission electron microscopy. It must be capable of analysis at above-ambient temperatures, and of electrochemical characterization.
  • a stage for in situ mechanical testing (compression, traction, bending, indentation) using environmental scanning electron microscopy, including at temperatures above ambient.
  • a device for local measurement of sample deformation when performing tensile tests at temperature, using an existing environmental scanning electron microscopy stage.
  • a plasma cleaner for cleaning samples, TEM holders and SEM stages.

 

Funding

The project is led by INSA Lyon, a leading engineering school in France.

It is supported by the CPER 2021-2027 program and the FEDER-FSE+ Auvergne-Rhône-Alpes 2021-2027 program.

In practice

The equipment will be purchased via a contract with separate lots, to be published in summer 2025.
