Our hypothesis from prior work was confirmed: the mechanical load acting on the hydrogel packing determines its creep rate. Very satisfying to see such intuition work out! J.A. Dijksman, T. Mullin — Soft Matter 20, 4015–4020 (2024) 10.1039/d3sm01755a

Salamina Grain Workshop
Traveling to Masseria Salamina for a fantastic setting to do science in small groups. The location was perfect, food was amazing, the pool refreshing, and despite the distraction, lots of science got done. And Bari, the closest major town, has huge grains for coastal protection.
Science fair fun
We had a demo at the annual EXPEDITIE NEXT, in Zwolle this time. We’ll be back next year with more fluidized beds, hourglasses, kinetic sand, Janssen effects and maybe more!
Identifying feed characteristics that affect the pellet manufacturing of livestock diets containing different coproducts

AERC Leeds
We were visiting Leeds, UK for the always fantastic Annual European Rheology Conference. There was too much good content to take too many pictures!
Capillary Flow-MRI of Micronized Fat Crystal Dispersions: Effect of Shear History on Microstructure and Flow

The gravity of the situation
Visiting Olfa D’Angelo doing hypergravity research on granular materials at ESA / ESTEC in Noordwijk. The museum visit was the cherry on the cake.
Rate dependence in adhesive particle–particle contacts affect ceramic suspension bulk flow behavior
Combining rheometry and custom AFM to reveal how adhesive contact forces affect the flow behavior of a suspension. Z. Farmani, J.A. Dijksman — Powder Technology 434 (2024) 10.1016/j.powtec.2023.119353
Physics @ Veldhoven 2024
The annual gathering of physicists working in The Netherlands took place again. What a great meeting, as always. The Byzantine location keeps amusing me and there is also plenty of applied physics going on!
Viscoelastic material properties determine the contact mechanics of hydrogel spheres
The title speaks for itself. Hydrogel spheres are viscoelastic, both under compression and shear. C. Shakya, J. van der Gucht, J.A. Dijksman — Frontiers in Physics 12 (2024) 10.3389/fphy.2024.1334325
