NMR of glass and nuclear waste materials
Developping NMR methodology for nuclear waste glasses

17O MQMAS NMR spectroscopy is a powerful techniques for the elucidation of glass structure (here applied to a ternary borosilicate glass). Quantitative modeling of such spectra is prerequisite for devising structural models of glass structure.



Over the years solid state NMR has proven to be one the most powerful and promising spectroscopy for structural studies of complex materials such as glasses. Reseashes are accired out in our lab in the context of nuclear waste materials.

We are applying and developping advanced NMR techniques for the stuctural characterization of those materials, adressing general issues concerning their structure, the role of each of their individual component, their long term behavior (chemical durability, irradiation effect), incorporation mechanism of low-solubility elements (rare-earth, transition elements,...) . In support of those expeirmental data, we put lot of efforts in processing and modelling NMR data to extract valuable information.
