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.
Les grandes installations de l’IRAMIS, telles que les spectromètres de diffusion, de diffraction et les stations d’imagerie de neutrons du LLB, sont particulièrement adaptées à l’étude des propriétés physiques de la matière condensée.
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.
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.
