Capacité de stockage de l’oxygène géante dans BaCoO3−δ sondée par une mesure couplée in-situ de thermogravimétrie (TGA) et de diffraction de neutrons
Jérôme Rouquette et Claire Colin Lien vers la publication. Les pérovskites à base de cobaltate de barium (BaCoO3-δ) et les nanocomposites associés ont fait l’objet de nombreuses études dans le domaine des dispositifs de stockage et de conversion d’énergie, principalement en raison de leur stœchiométrie d’oxygène flexible et de la possibilité de moduler les états […]
How to improve chocolate tempering? Use SANS!
Anne-Laure Fameau Lien vers la publication. Chocolate has played an important role in human culture since about 350 BC, when the Aztecs were drinking fermented cocoa. Today, chocolate gives psychological pleasure all around the world. Chocolate manufacturing is not easy and requires a complex tempering (mixing and heating) procedure to direct the crystallization of cocoa […]

Neutron diffraction for studying (supra)polymer/solvent molecular compounds
J.M. GuenetInstitut Charles Sadron, CNRS-Unistra, 23 rue du Loess, 67034 STRASBOURG Cedex2 Neutrons have been extensively used in the small angle range (SANS) for investigating the large-scale structures of (supra)polymers. Another interesting aspect of neutrons lies in their use in the wide-angle, or diffraction range for studying the crystalline organization of co-crystals obtained from polymers […]
