Light sheet imaging in granular materials: interdisciplinary opportunities
Light sheet imaging remains a valuable tool for studying dense granular materials; in this work we provide more background, new techniques and applications. Joshua A. Dijksman, Alexei D. Filippov, Ahmed Al Harraq, Babak Vajdi Hokmabad, Sujit S. Datta, Elisabeth Bowman — Granular Matter 28 (2026) 10.1007/s10035-026-01622-2
A temperature dependent framework to predict and control physical pellet quality in biomass extrusion
Making durable pellets out of loose powders is a general engineering challenge. Here we add insights on the role of temperature in the various phases of this extrusion process. Richard T. Benders, Joshua A. Dijksman, Thomas M.M. Bastiaansen, Raoul Fix, Jasper van der Gucht, Menno Thomas — Chemical Engineering Journal 530, 173569 (2026) 10.1016/j.cej.2026.173569

Congratulations! The thesis can be found here.
Strain dependent viscous response describes the mechanics of cohesionless soft granular materials
Hydrogel packings reveal a curious rate dependence that can be capture with a modified non-linear spring-dashpot model. Chandan Shakya, Luca Placidi, Anil Misra, Lars Kool, Anke Lindner, Jasper van der Gucht, Joshua A. Dijksman — Physical Review Materials 10 (2026) 10.1103/6mgb-p46h
The lubricating effect of fats on pellet manufacturing
Adding fats helps – sometimes – in lubricating of pellet manufacturing. T.M.M. Bastiaansen, G. Verge-Mèrida, R.T. Benders, J.A. Dijksman, M. Thomas, W.H. Hendriks, S. de Vries, M. Devant, G. Bosch — Animal Feed Science and Technology 326 (2025) 10.1016/j.anifeedsci.2025.116390
Agglomeration during reactive extrusion of particle-based biomass pellets
What makes them stick? Temperature certainly plays a role. Richard T. Benders, Menno Thomas, Thomas M.M. Bastiaansen, Jasper van der Gucht, Joshua A. Dijksman — Powders & Grains 2025 – 10th International Conference on Micromechanics on Granular Media (2025) https://doi.org/10.1051/epjconf/202534001008
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. Yael Cohen, Amit Schiller, Dong Wang, Joshua A. Dijksman, Michael Moshe — Physical Review Materials 9 (2025) 10.1103/ppmg-ypkw
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. Xiaoyan Ye, Kaizhao Qin, Rui Yang, Joshua A. Dijksman — Journal of Fluid Mechanics 1013 (2025) 10.1017/jfm.2025.10207
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.
