Mössbauer platform
Responsible
Moulay Tahar Sougrati
Scientific contributions
- Sn and Fe speciation: identification of species containing tin or iron (transmission and/or diffusion mode) in their chemical environment, quantitative evaluation of their proportions, access to the databases of the Mössbauer Effect Data Center (Dalian, China)
- Characterization of the local electronic structure for the element being probed: degree of oxidation, coordination
- Studies of reaction mechanisms
- Ex situ, in situ, operando measurements, Mössbauer - X diffraction couplings
- Ab initio calculations of Mössbauer parameters
- Quantitative interpretations, modeling of reaction mechanisms
> Resources supported by RS2E as an analytical platform
Equipment:
Two spectrometers (57Fe, 119Sn) from the laboratory are made available to the CRA for platform-type operation.
