  • Characterisation of water dynamics in polymer electrolyte fuel cells is important for technology development. Here, the authors demonstrate a 4D neutron imaging technique, enabling quantitative analysis of the local water evolution, and identify performance parameters for water management.

  • The combination of X-ray and neutron CT enables 4D studies, i.e. to explore the evolution of 3D structures with time. Here the authors apply this approach to a Li-ion primary cell, revealing elsewhere unseen trends in the spatial distribution of performance aided by a new ‘unrolling’ methodology.

  • Laser-plasma electron accelerators are ultracompact and come with an embedded betatron X-ray source with small source size and ultrashort pulse length. The authors combine the edge illumination-beam tracking technique with a compact plasma X-ray source and present a demonstration of multimodal imaging down to the femtosecond timescale.
