Jean-Claude Jumas

Dr. Jean-Claude Jumas was graduated from the University of Montpellier. He is docteur ès Sciences and his habilitation thesis presented in 1975 is entitled Study of Sn(IV) coordination in Na2S-SnS2, BaS-SnS2 et PbS-SnS2 systems by X-ray diffraction and Mössbauer spectroscopy.

He was appointed CNRS researcher at the Laboratoire de Physicochimie de la Matière Condensée until 2000 and then at the Laboratoire des Agrégats Moléculaires et Matériaux Inorganiques, which is now Equipe Agrégats, Interfaces et Matériaux pour l’Energie (AIME) of the Institut Charles Gerhardt de Montpellier (ICGM).

He founded the Mössbauer group of Montpellier in the early eighties in close collaboration with Pr. Ulrich Gonser, Dr. Michael Uhrmacher and Pr. Guido Langouche who encouraged him to develop applications of the Mössbauer spectroscopy in solid state chemistry. He was the leader of the Mössbauer group of Montpellier for about four decades that combined both theoretical and experimental approaches for a better overall understanding of the relationships between synthesis conditions, structures and properties of materials.

Dr. Jean-Claude Jumas has managed different fundamental and applied multidisciplinary research projects including a large part of Mössbauer spectroscopy. For example, he developed an original methodology to study structure-properties relationships in complex materials within European programs. He was also strongly involved in the analysis and applications of electronic and ionic transfers in materials for energy (catalysis, Li-ion and Na-ion batteries), proposing new experimental protocols and in situ cells for operando Mössbauer measurements. To this end, he initiated and developed strong collaborations with industry: (Institut Français du Pétrole, St Gobain, SAFT, etc.), public organisms (ADEME, CNES, CNRS, INRA) and research networks (French network for electrochemical energy storage RS2E, European research institute ALISTORE).

Dr. Jean-Clause Jumas has been actively involved in the diffusion of educational and scientific information as member of IBAME, MEDC international advisory board and Mössbauer century club. He took part in the creation and organization of the French Speaking Group of Mössbauer Spectroscopy (GFSM) and organized different national thematic schools on the combined applications of different experimental spectroscopies, including Mössbauer spectroscopy, to characterize complex materials and reaction mechanisms. He organized different interdisciplinary schools on nuclear spectroscopies (GALERNE, CNRS) from 1987 to 2004, different GFSM conferences and ICAME in Montpellier (2005).

Dr. Jean-Claude Jumas published more than 350 papers, most of them concerning the applications of 57Fe, 119Sn, 121Sb and 125Te Mössbauer spectroscopies in solid state chemistry and materials science. He is now IBAME fellow and emeritus research director. Last but not least, he is strongly involved in the development of the Football club of Jacou-Clapiers (France) as president. A new challenge!
