Isosbestic points in time resolved SAXS: from spectroscopic analogy to model free structural markers during colloidal gelation
Alain Gibaud, Wilbert J. Smit, Safa Jamali +1
Gelation is the transition from a fluid state into a system-spanning, out of equilibrim soft-solid network through a hierarchical process that couples local particle interactions t…
Tracking microscopic irreversibility during yielding of a colloidal fractal gel with Rheo-Echo-XPCS
William Chèvremont, Julien Bauland, Emmeline Brassac +4
Understanding how microscopic structural dynamics relate to macroscopic mechanical response during yielding remains a central challenge in soft matter physics. Here, we introduce r…
In vivo measurements of fascia lata effective mechanics combined to a memory fiber recruitment viscoelastic modeling approach
Franck Germain, Thomas Gibaud
The fascia lata plays a central role in force transmission and body mechanics, yet its in vivo mechanical behavior remains poorly characterized. Existing approaches -- shear wave e…
Acoustic modulation of shear thickening transition in dense adhesive suspensions
Aoxuan Wang, Fabrice Toussaint, Thomas Gibaud
Discontinuous shear thickening (DST) in dense suspensions leads to flow instabilities that limit processing in many systems. While high-power ultrasound has been reported to reduce…
Imprinting Macroscopic Fracture during Gelation: A Mechanism for Tuning Colloidal Gels
Wilbert J. Smit, Thomas Gibaud, Sébastien Manneville +1
Colloidal gels form through the sol-gel transition of attractive particle suspensions, where local aggregation leads to a space-spanning network with solid-like properties. Their m…
Shear-driven memory effects in carbon black gels
Julien Bauland, Thomas Gibaud
In recent years, significant effort has been devoted to developing smart materials whose mechanical properties can adapt under physical stimuli. Particulate colloidal gels, which b…
