Tribology of hard particles lubricating soft surfaces
The title speaks a thousand words. Well only seven, but that’s enough in this case. Raisa E.D. Rudge, Karlijn Theunissen, Jason R. Stokes, Elke Scholten, Joshua A. Dijksman — Physical Review Materials 5 (2021) 10.1103/PhysRevMaterials.5.055604
Period 6 teaching
Fortunately we now have recorded lectures to serve as flipped classroom material! Thanks Peter for editing.
Advanced Soft Matter PCC31806
This year the Advanced Soft Matter practicum has a project related to the Smart Dust team. The Smart Dust team will be doing drop tower experiments in Bremen, to detect the collective behavior of a set of “smart” particles.
The SmartDust team can do microgravity experiments in Bremen!
The team of students from Otto von Guericke University, where our collaborator Ralf Stannarius works, will do granular gas experiments with balls equipped with smart sensors!

Onsager reciprocity is a pain to explain… Even with Callen‘s help!
Hooked on mushrooms: Preparation and mechanics of a bioinspired soft probabilistic fastener
Soft probabilistic fasteners (aka Velcro) can be made. Preeti Sharma, Vittorio Saggiomo, Vincent van der Doef, Marleen Kamperman, Joshua A. Dijksman — Biointerphases 16 (2021) 10.1116/6.0000634
Molecular control over vitrimer-like mechanics – tuneable dynamic motifs based on the Hammett equation in polyimine materials
Cool polymer rheology work showing the potential of covalent adaptable networks to obtain new material properties – together with the group of Maarten Smulders.
Rotational diffusion and rotational correlations in frictional amorphous disk packings under shear
Rotational dynamics of individual particles in sheared granular materials is surprisingly “thermal” and indicative of mesoscopic mechanisms that underpin concepts such as shear jamming. Here we reanalyzed existing data set with the help of a very multidisciplinary team. Dong Wang, Nima Nejadsadeghi, Yan Li, Shashi Shekhar, Anil Misra, Joshua A.
