TL;DR: High-speed synchrotron X-ray computed tomography and radiography is used, in conjunction with thermal imaging, to track the evolution of internal structural damage and thermal behaviour during initiation and propagation of thermal runaway in lithium-ion batteries, yielding insights into key degradation modes.

TL;DR: This work shows that the remarkable insensitivity of the mechanical properties to the liquid content is due to the particular organization of the liquid in the pile into open structures, and presents evidence that this concept is also valid for systems with non-spherical grains.

TL;DR: The demonstration of ghost imaging with hard x rays may open the way to protocols to reduce radiation damage in medical imaging and in nondestructive structural characterization using free electron lasers.

TL;DR: A combination of high-speed operando tomography, thermal imaging and electrochemical measurements is used to probe the degradation mechanisms leading up to overcharge-induced thermal runaway of a LiCoO2 pouch cell, through its interrelated dynamic structural, thermal and electrical responses.

TL;DR: In this paper, the authors describe some observations on liquid bridge coordination numbers and liquid bridge volumes in model granular materials consisting of glass beads, and also describe experiments on the dynamic deformation of a wet granular material, which reveal a type of shear-thinning behavior that they attribute to the shear rate dependence of liquid bridge volume.
