Nanostructured materials and nanocomposites
In very many situations, whether it be in fluids or materials for every day use, or in biological systems, matter is present in a highly dispersed form. It follows an extraordinary range of behaviour due to structural combinations, from the molecular to the mesoscopic and macroscopic scale.
Supramolecular, structural and coordination chemistry
In this domain, the field of study of DRECAM covers the molecule to the controlled assembly of molecules. This approach extends from the fine comprehension of molecule - metal coordination and interaction, to the construction and the synthesis of molecular assemblies having specific properties (structure, complexation, solubility, biological activity) and finally to their characterization by specific tools such as solid or liquid NMR, X-ray or neutron scattering and near field microscopies.
Thématiques NFMQ : magnétisme, transitions de phase - Etudes par diffusion de neutrons
Le magnétisme est un domaine d’intérêt majeur, car combiné à l’électronique, il a modifié en profondeur notre vie quotidienne : sous forme de capteurs, d’actionneurs, de dispositifs nomades (téléphones, tablettes, ordinateurs portables), de matériaux aux capacités de stockage accrues pour l'enregistrement magnétique de toutes nos données informatiques., etc...
Unconventional superconductivity: neutron spectroscopy and theory
In the last two decades, new superconducting (SC) compounds, exhibiting surprisingly high critical temperatures (Tc), have been discovered. In contrast to conventional superconductors, the SC order parameter is not isotropic, neither in cuprates nor in Fe-based systems. This ignited a search for new SC pairing mechanisms based on the existence of rather strong electronic interactions.
