Dr Jean-Claude Jumas, Emeritus Research Director (CNRS) at the Laboratory for Aggregates, Interfaces and Materials for Energy, Charles Gerhardt Institute for Molecular Chemistry and Materials, in Montpellier (France) is the team leader of the “Electronic and ionic transfer” group (20 persons). He has also the responsibility of the “Analysis and Characterization Platform” of the Balard Chemistry Pole and the “X-ray and Gamma Network” of the University of Montpellier 2.

Its research activities are focused on materials with electronic or ionic transfer properties mainly in the field of energy and sustainable development: electrode materials for lithium-ion batteries and supported catalysts used in processes of catalytic transformation of hydrocarbons for automotive or petrochemical purposes.

In the field of new electrode materials its studies mainly concern the negative electrode (transition element - p element oxides, chalcogenides or alloys) including chemical syntheses (ceramic, sol-gel and boil milling routes), physicochemical, structural, electronic (Mössbauer spectrometry, X-ray Absorption Spectroscopy) and electrochemical characterisations and modelling. He has developed Mössbauer spectroscopy as a powerful tool for Solid State and Materials Chemistry to study the various steps of chemical synthesis, the charge/discharge process of electrode materials or catalytic cycles (ex situ or in situ).

Dr Jean-Claude Jumas is member of the Mössbauer Century Club , established by the Mössbauer Effect Data Center to recognize its contributions in the field of Mössbauer Spectroscopy.
