Lab under construction
We are moving into a new lab room, with new desks, facilities, curtains for laser work, and a couch!
Strengthening Interactions
Another workshop organized by and at the Lorentz Center in Leiden. It was good to spend time with all the granular experts!
Visiting Rennes
Visiting Rennes again after Dygram 2006 shows that noting has changed, except perhaps the temperature. Thanks Axelle Amon for hosting!
Particle contact evolution: A precursor mechanism for earthquake-induced liquefaction prior to pore-pressure buildup
Measuring pore pressure dynamics before and at the moment an earthquake happens reveals that the event is triggered in the contacts! Hu Zheng, Yuxiang Hu, Yiqiu Zhao, Joshua A. Dijksman, Minyi Zhu, Dong Wang, Wuwei Mao, Wei Teng, Lihui Li, Yufeng Gao, Yu Huang — The Innovation 7, 101394 (2026) 10.1016/j.xinn.2026.101394
Project Prepared
The course “Project” starts again this June – 100+ ast year BSc students come together in 35+ teams to spend time in the Amsterdam Physics & Astronomy research labs!
Salamina mon amour
The famous Salamina Grain Works workshop were another marvel this year. Thanks Luigi for organizing an impeccable meeting at a impossibly perfect location.

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
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
