Laboratory of Soft Materials

Welcome to the webpages of the Soft Materials Group at the ETH Zürich. We are part of the department of Materials (D-MATL). Our research interests relate to soft matter and polymers,  with an emphasis on structural and rheological properties. Materials classes belonging to soft matter range from polymers, colloids over surfactive or active components and mixtures thereof. Recently there has been a strong focus on interface dominated materials in our research.

Our work has a strong fundamental focus, but applications domains are broad. We strive to find high end applications of our work which hopefuly impact society in a longer run, with human health and materials or processes which improve sustainability being most of the time at the core of our work.

On behalf of the Soft Materials group, I wish you enjoyable reading.

Jan Vermant.

 08.25 Care about Beer, Foams and interfacial rheology?  Read : external page The Hidden Subtlety of Beer Foam Stability: A Blueprint for Advanced Foam Formulations," in Physics of Fluids (Vol.37, Issue 8). The interface stress boundary condition depends on fermentation...

you may also find other recent papers on interfacial rheometry of interest : Rodriguez-Hakim, M., Jaensson, N., & Vermant, J. (2025). external page Towards operating windows for pendant drop methods: tensiometry and rheometry of elastic interfaces. Rheologica Acta or about the lifetime of free standing films : Chatzigiannakis, Emmanouil, and Jan Vermant. "external page PERSPECTIVE: Interfacial stresses in thin film drainage: Subtle yet significant." Journal of Rheology 68, no. 4 (2024): 655-663.

Soon you'll see work on the relation between interfacial rheology and the reasons why we sigh!- take a deep breath and check back soon. 

 

06.25 We made some progress on understanding colloidal gel mechanics : check out Muller, F. J., Ramakrishna, S. N., Isa, L., & Vermant, J. (2025). Texternal page uning Colloidal Gel Properties: The Influence of Central and Noncentral Forces. Langmuir, 41(5), 3098-3107, and and Müller, Florence J., Keyu Yang, Lucio Isa, and Jan Vermant. "Tuning particle aspect ratio and surface roughness to modulate properties in colloidal gels." Journal of Colloid and Interface Science 690 (2025): 137274 about how shape, roughness and attraction influence gel mechanics. The we know flow also has a huge efect : see Colombo, Gabriele, Pierre Lehericey, Florence J. Müller, Madhu V. Majji, Hanumantha Rao Vutukuri, James W. Swan, and Jan Vermant. "external page Kinetic Pathways to Gelation and Effects of Flow-Induced Structuring in Depletion Gels." Industrial & Engineering Chemistry Research 64, no. 8 (2025): 4581-4595 in W.R.
