JDN21 - 21emes journées de la diffusion neutronique : Neutrons and Materials for energyInternational audienceThe French Neutron Society (SFN) traditionally organizes annually a thematic school on a particular aspect of neutron scattering techniques. The school “NEUTRONS AND MATERIALS FOR ENERGY", held from 21th to 25th June 2013 in Sète in the South of France, during the 21th edition of the “Journées de la diffusion Neutronique”, focused on the use of neutron scattering to characterize materials in the wide field of energy storage and transformation. The development of new materials for energy is one of the major challenges of this century and is based largely on a thorough understanding of the origins of multi-scale properties. Neutron sca...
