Jeudi 10 septembre 2026 Phase separation of polyelectrolyte/protein complexes and diffusion dynamics in the concentrated (coacervate) phase. Christophe Tribet (C3M, ESPCI)
Complex coacervation, a phase separation driven by protein association with flexible, usually ionized macromolecules, is emerging as a biomimetic strategy for controlled catalysis and protein stabilization [1]. Coacervates may enhance formulations of highly concentrated (>200 g/L) therapeutic (e.g. IgG antibodies), while (…)

Foam formation dynamics in depressurised complex fluids

Armand Hakopian — 2026-07-20T13:49:40Z

Post-doctoral position: 12 months. Start date: Autumn 2026. Position open until filled
Hosting laboratory: Soft Matter Science and Engineering Laboratory - ESPCI PSL, Paris, France https://www.simm.espci.fr/-Accueil-.html Contact :
Aqueous foams, composed of gas bubbles dispersed in a liquid phase, are fascinating soft materials. They are inherently dynamic, evolving over time and eventually disappearing. This temporal behavior makes them both challenging and rewarding to study. While (…)

Coarsening-driven bubble dynamics in wet foam

Armand Hakopian — 2026-05-18T15:28:26Z

Internship proposal
Laboratoire Sciences et Ingénierie de la Matière Molle, (SIMM)
Address: ESPCI, 10 Rue Vauquelin 75005 Paris
Head: Jean-Baptiste d'Espinose
Supervisors: Anniina Salonen, Reinhard Höhler
Contact : ,
Possibility of PhD: yes (funding pending from ESA/CNES)
Aqueous foams are dispersions of gas bubbles in a liquid. These out of equilibrium systems will evolve towards disappearance through several ageing mechanism. Surface tension drives the growth of bubble size, (…)
