The topological properties of quasiparticles, such as skyrmions and vortices, have the potential to offer extraordinary metastability through topological protection, and drive motion with minimal electrical current excitation. This has promising impl

Abstract Radiation-induced materials degradation is a key concern in limiting the performance of nuclear materials. The formation of nanoscale void and gas bubble superlattices in metals and alloys under radiation environments can effectively mitigat

Palladium can absorb high volumes of hydrogen, but the morphology and 3D displacements occurring during palladium hydride phase formation are not fully characterized in the literature. Here, the authors use Bragg coherent diffraction imaging to map t

Study of structural inhomogeneities in zeolites is important but limited by conventional techniques. Here the authors employ in situ free-electron-laser-based time-resolved coherent X-ray diffraction imaging to visualize the effect of these inhomogen

Direct visualisation of site-specific strain variations of catalysts is needed to better understand catalytic properties. Here, the authors determine with attojoule precision that the well-known catalytic hysteresis phenomenon occurs at single partic
