  • In this study, dynamic X-ray techniques are used to directly observe 3D secondary flows in moving grains - shedding light on complex behaviours in granular materials and opaque substances like pastes, emulsions, and other soft matter.

  • When compacting a brittle porous medium—think stepping on fresh snow—patterns develop. Simulations and densification experiments with cereals now provide an understanding of compaction patterns in terms of a lattice model with breakable springs.

  • Tracking the deformation of opaque materials under their surfaces is fascinating, yet a challenging task, which has been constrained to static conditions or model materials to date. Here, Baker et al. develop X-ray rheography to reconstruct three-dimensional velocity fields in general granular media.

  • In superconducting thin films of a few atomic layers, surface and bulk orders may compete. Here, the authors measure how the Pearl length, which characterizes the distribution of magnetic field in vortices, varies with thickness in NbSe2, showing that surface superconductivity dominates at low thickness.
