Thèmes de recherche
My research focuses on elucidating the structure–property relationships in Layered Double Hydroxides (LDHs), whose functional performance depends critically on their atomic-scale structure and the nature of their structural disorder. These materials commonly exhibit cation disorder, interlayer dynamics, stacking faults, and low crystallinity — features that complicate conventional structural analysis but directly impact electrochemical behavior, ion exchange, and catalytic activity.
To address these challenges, I apply a comprehensive, multiscale X-ray scattering approach, tailored for structurally complex and poorly ordered systems:
- Powder X-ray Diffraction (PXRD):
• Line profile analysis to extract microstructural parameters (e.g., crystallite size, strain, stacking coherence) and to reconstruct electron density profiles along the stacking direction, revealing interlayer speciation and organization.
• 1D layer-by-layer XRD simulations, which model the structure as a sequence of individual layers rather than an ideal 3D lattice — essential for interpreting stacking faults and turbostratic disorder in layered materials. - Energy-Dispersive XRD: used for time-resolved experiments to monitor phase evolution and reactive transformations in situ.
- Total Scattering and PDF Analysis:provides access to short- and medium-range order in disordered or nanostructured LDHs, beyond the limits of classical diffraction.
