PHILIPPE MOREAU

Présentation

Professor in Chemistry at the University of Nantes Diplôme Ingénieur ENSIC 1991 (Nancy, France); Ph.D. 1994 (Nantes, France) ; Cavendish 1996-1998 (Cambridge, UK) ST2E group - Institut des Matériaux Jean Rouxel - University of Nantes - Centre de MicroCaractérisation (Microscopy Center) - CNRS

Philippe Moreau is a graduate of the Ecole Nationale Supérieure des Industries Chimiques (ENSIC in Nancy, France : &quot;Grande Ecole&quot; specialised in Chemical Engeneering). During his PhD, his focus became redirected towards the study of materials. The subject was &quot;Interactions in mercury intercalated TiS2 and TaS2&quot; under the supervision of Prof. G. Ouvrard at the Institut des Materiaux Jean Rouxel in 1994. While at the Cavendish Laboratory (Cambridge, England) in his postdoctoral position under the supervision of Prof. A. Howie, he got involved in Electron Energy Loss Spectroscopy and still is involved in this field to date. He became Maître de Conférences (lecturer) at the University of Nantes in 1998 and professor in 2019 and teaches inorganic chemistry, electron microscopy and, photon and electron based spectroscopies. His current interests are in the study of lithium battery materials using EELS and electron microscopy, the development of the understanding of the low energy loss region in EELS spectra and the optimised comparison of experimental spectra with ab initio calculations. He is in charge of the electronic microscopy plateforme based at IMN (5 engineers, 2TEMs, 1FIB, 4 SEMs).

Research Interests Statement

The powerful balance between chemistry and physics becomes increasingly obvious with each passing day, especially as far as the study of materials is concerned. Their macroscopic physical properties are often linked to their more local chemistry, i. e. the &quot;chemical bond&quot;, which was very dear to late Prof. Jean Rouxel (founder of the Institut bearing his name). This &quot;chemical bond&quot; results directly from the electronic structure of the material. The determination of which, is thus a major challenge in order to get a better understanding of the material properties. In the context of the ever-growing miniaturisation of devices and the tremendous development of nanomaterials, a localised probe of this electronic structure becomes essential and Electron Energy Loss Spectroscopy in a Transmission Electron Microscope is the ideal tool (see our Microscopy plateforme website ). With an energy resolution of less than an eV and a probe smaller than 1 nm, EELS has revealed unrivalled possibilities. If one wants to go beyond the &quot;finger print&quot; analysis of the EELS spectra obtained, ab initio calculations of the spectra are necessary. These calculations, within the Density Functional Theory (DFT), are also essential tools in the visualisation of the electron density in the materials. Consequently, performing the experimental EELS technique and the theoretical DFT calculations in parallel, constitutes one of the most promising research paths in view of understanding structures and properties of new materials.

Current research interests are :

Study of lithium batteries, using Electron Energy Loss Spectroscopy

Development of new methods of characterisation using VEELS/ our understanding of Low Energy-Loss Spectra (plasmons)

Development of 3D microscopy and operando experiments with various materials of interest for the Institute.

Current Research Projects :

Analysis of Lithium battery materials : different cathode composite electrodes (LFP, NMC) / anodes (Si)

3D study of filtration membranes (Collaboration with E. Couallier, GEPEA)

Study of beam sensitive materials (with EELS) such as organic materials.
