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

🎉🍾 Warm congratulations to Pierre Lehéricey on successfully defending his PhD @ETH_en on the mechanisms of #plasticity in depletion #gels! Lovely trip to snowy Zürich - grateful to Jan Vermant for the invitation to serve on Pierre’s committee! #everythingflows #excelsior

🚨Lise's extensive exp. work on #cellulose #nanocrystals in collab w/ S. Manneville is now on @arxiv 👉#Gelation dynamics of charged #colloidal rods: #critical behaviour and time-connectivity superposition principle! Read it now▶️ arxiv.org/pdf/2603.11366 cc @CNRSphysique @lpensl – at Denver, CO

At the @APSphysics Global Physics Meeting in Denver next week?✈️ Join our Focus Session MAR-L65: "New Perspectives on #GelNetworks", co-organized with Guilhem P. Baeza! Don’t miss the great speaker lineup on NMR, rheometry, etc. ➡️summit.aps.org/events/MAR-L6… cc @CNRSphysique @lpensl

Wrapping up a snowy & productive 2-week stay @MITMechE in wonderful #HML with @garethmckinley and Irmgard Bischofberger! Insightful discussions, great seminars… and even a Super Bowl! 😄🏉🌨️ Farewell, #Boston! Big thanks to Région Rhône-Alpes for the support! @auvergnerhalpes

🥳Our review on #Pattern Formation & #Instabilities in Particulate #Suspensions just came out in @AnnualReviews Enjoy the dimensionless jungle🙊 in #openaccess - doi.org/10.1146/annurev-flui… cc @CNRSphysique @CNRS @lpensl @MITMechE @IJMonod @UMNews

🍾🎉 Congratulations to Dr Nikita Goltiakov 👨‍🎓for a rich PhD defense on a novel aggregation framework modeling face-selective #particle assembly with applications to heterogeneous #catalyst design at #IFPEN - thanks to Maxime Moreaud & Manuel Corral Valero for the invitation.

🎉🍾Congratulations to Dr. Louanne Pommier for her excellent #PhD defense @espci on sol-gel transitions in #chitosan-betaGP systems! Truly enjoyed & learned a lot reviewing her manuscript. Many thanks to Michel Cloitre, Laurent Corté & Stefano Aime for the invitation! @psl_univ

🤔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

🚨We have an opening for a 2-year #postdoc position in our group @lpensl, sponsored by @AgenceRecherche, to work on the Dynamics and Shear-Induced #Gelation of #Colloid-#Polymer Suspensions! Apply before Nov. 10th and join us in #Lyon!🥳👉 emploi.cnrs.fr/Offres/CDD/UM… cc @SoRheology

PhD students 🇺🇸 interested in soft matter, #gels & #rheology - the Chateaubriand Fellowship 2026-27 supports research stays (4-9 months) in France 🇫🇷. Join our lab @lpensl & collaborate across the Atlantic! Apply 👉 chateaubriand-fellowship.org… cc @MITMechE @Georgetown RT appreciated!

🚨Paper alert! Our review on #Pattern Formation and #Instabilities in Particulate #Suspensions just came out in @AnnualReviews of Fluid Mechanics! Fun & fantastic teamwork with Marc-Antoine Fardin, Sungyon Lee & Irmgard Bischofberger! 👉doi.org/10.1146/annurev-flui… cc @CNRSphysique

🔬🥼🧪Kicking off this year #science fest @lpensl with an awesome team from @PhysiqueENSL! The booth is showing visual & pedagogical #experiments on memory effects in #viscoelastic materials! It’s free for all on October 4th! 👉Join us! Cc @AgenceRecherche @CNRSphysique @CNRS

🎉Back by popular demand! The Summer School on #SoftMatter returns to @IES_Cargese in Corsica 🌊☀️in July 2026. A unique gathering where soft matter physics meets sensory perception 🌀👂👀! 📚Program, list of amazing speakers & registration: 👉 softsensory.sciencesconf.org… cc @CNRS

Wonderful gathering yesterday for the Gay-Lussac academic day @saintgobain Recherche in #Paris to attend presentations from PhD students supported by #SaintGobain. Justine presented her latest results on micro-mechanical testing of tile #adhesive! Cc @CNRSphysique @lpensl @CNRS

🥳Gauthier's masterpiece on carbon black-CMC #hydrogels is out on #arXiv! We probe their #rheology under LAOStrain, combining rheometry with #TRUSAXS & in situ conductivity. Our work unravels distinct #yielding mechanisms in conductive vs insulating #gels. arxiv.org/abs/2509.08966

Biominerals, #glass transition, #foam drainage, #neutron scattering, #drying of colloidal dispersions, drop impacts at low #Reynolds number, MD #simulations of #collagen microfibrils, etc. We had a blast! 🙌Thanks to all the participants for such a rich & dynamic annual meeting!

Kicking off day 2 of the @CNRS GDR #SoPhy annual meeting @ScienceSorbonne with @AkivaAnat giving a talk on the soft matter of #bones - #collagen! Stimulating discussions ahead with @gdrbiomim members! #everythingflows big thanks to @CNRSphysique @CNRSingenierie for funding! #cnrs

The 2025 annual meeting of GDR SoPhy - sponsored by @CNRS, @gdrbiomim and @CNRSphysique - kicks off in Paris @ScienceSorbonne on Monday!📅 Check the updated program 👉 sophy2025.sciencesconf.org/?… Looking forward to this exciting #interdisciplinary event! cc @CNRSchimie @lpensl #cnrs
