Ever wondered what the microstructure of opaque colloidal #gels looks like? We obtained beautiful images by X-ray #tomorheoscopy @psich_en that reveal history-dependent, large-scale heterogeneities! Read about it in our new #preprint👉 arxiv.org/pdf/2603.16804 cc @CNRSphysique

🤔What happens when a #colloidal #gel forms under shear? Strong oscillations during gelation carve macroscopic #fracture patterns into the gel, leaving a clean rheological signature captured by a simple #fractional model - and making gels more #ductile!📑👉arxiv.org/abs/2511.19713

Thrilled to share that Gauthier Legrand just received the 2025 PhD Thesis Award from the French #Rheology Group! 🏆His work explored how dispersions of carbon black & CMC form hydrogels with distinct microstructures & mechanical responses! Congrats Gauthier! @lpensl @CNRSphysique
