We love interactions, in particular with particles
Exopolymer gels are surprisingly tricky to measure properly. But we managed.

Starting the class while Melorman is playing – enjoying beautiful relaxing earcandy to prepare for some focused efforts! Thanks Antonis for yor wonderful music.
Great course, which has been running for years. Glad to have attended as a student, and now good to be a lecturer here!
Depending on the ingredients, multiple reheological mechanisms can occur simultaneously. That’s why food systems are often such good model systems for soft matter physics.

And some other wonderful training sessions in Budapest, Paris and Grenoble…
Fluid films flowing down a tube develop fingers; fluid films flowing down an incline can – but convergent fluids on a planar substrate suppress instabilities. What about the in-between situation? We answer that question here.

It is the viscous drag of the co-moving solid-like fluid blob around the intruder that decelerates said intruder impacting a cornstarch suspension, not the added mass or surface tension. A nice puzzle to solve! Thanks Scott for sharing original data.

Friction involves many length scales; here we cover the influence of molecular scale effects from “astringent agents”.
