Tom Mullin was visiting again, and the many interns and Project students also joing the fun!
Group dinner before summer
Rebounding hydrogel sphere water entry
Very satisfying to work with Xiaoyan Ye – who did all the heavylifting here – on this topic of how soft particles have a different way of impacting a “soft” water-air interface.

Odd-dipole screening in disordered matter
This is the kind of work that publishing open data makes possible – an entirely new interpretation of strain field observations in sheared granular materials.

Random evolutionary dynamics in predator–prey systems yields large, clustered ecosystems
The result of an MSc thesis and lots of hard work from Christian – making noisy ecosystem cluster into different subgroups is possible, but does require some minimal ingredients, it seems.

Visiting Strasbourg
Visiting Strasbourg, connecting with group alumni and giving a talk for a non-empty room! Thanks to Wiebke Drenckhan for hosting.
Predicting digesta retention times from dietary physicochemical properties in pigs
Can rheology say something about the retention time of digesta? It seems so – but more work is needed to better characterize the samples and improve statistics.

Dynamics of particle entrainment for glass particles suspended in various fluids
Lubricating interfaces with “third bodies” is common; here we do model studies to investigate how such lubricating suspensions introduce new lubrication regimes.

Physics @ Veldhoven
The national Dutch Physics Conference. Our artwork competed for best scientific image. We were among the last six, but didn’t get a prize.
Integrating Flow Testing and Particle Imaging: Advances in Characterising Granular Flows
How to combine bulk solids testing with imaging? Zohreh and team wrote a review article on the topic in the famous KONA journal.
Zohreh Farmani, Jan A. Wieringa, John van Duynhoven, Joshua A. Dijksman — KONA Powder and Particle Journal 42, 57–78 (2025)
Granular flow of 3D mixtures of soft and hard spheres
Not all granular samples are simple – often mixtures of soft and hard particles are present. The mixture flow behavior can be quite different, as it turns out.
