LRP at AERC 2025: a strong scientific presence in Lyon

From April 14 to 17, 2025, the city of Lyon hosted the 2025 edition of the Annual European Rheology Conference (AERC), a key event for the scientific community dedicated to rheology. The Laboratoire Rhéologie et Procédés (LRP) played a leading role, with nearly twenty oral contributions showcasing the diversity and richness of its research areas, as well as the active involvement of its PhD students, postdoctoral researchers, and scientists. The laboratory also stood out through its commitment to the organization of the event, notably via the scientific co-chairing by Nadia El Kissi.

This edition provided an opportunity to highlight LRP’s recent advances in several key areas of complex fluid mechanics, including microfluidics, 3D printing of gels, and materials processing.

The biosourced composite materials research axis—another pillar of the laboratory—was represented through original work on the multiscale structuring of cellulose nanocrystals for the development of new functional materials.

Biological flows also featured prominently, with presentations on fluid dynamics in blood microcapillaries and around intestinal villi, as well as on pulmonary and intestinal mucus.

Polymer rheology was addressed through talks on the controlled degradation of flocculants for wastewater treatment (in partnership with SIAPP), the design of self-healing copolymers, and the shaping of anisotropic biomaterials for soft tissue engineering.

Finally, the conference also showcased strong industrial collaborations, notably with TotalEnergies SE, Nippon Paint, and Rheonova, focusing on topics such as microfluidic flows, printing of complex fluids, and characterization of pulmonary mucus in biomedical contexts.

These presentations reflect the interdisciplinary approach championed by LRP—at the crossroads of rheology, complex fluids, and processing. AERC 2025 was a prime opportunity to share these results with the international community and to strengthen the scientific collaborations that drive innovation in rheology.
