DOI: 10.1002/adma.202211498
Abstract: 3D porous Zn‐metal anodes have aroused widespread interest for Zn‐ion batteries (ZIBs). Nevertheless, the notorious “top‐growth” dendrites caused by the intrinsic top‐concentrated ions and randomly distributed electrons may ultimately trigger a cell failure. Herein, an… read more here.

DOI: 10.1002/smll.202206572
Abstract: On-skin electronics based on impermeable elastomers and stacking structures often suffer from inferior sweat-repelling capabilities and severe mechanical mismatch between sub-layers employed, which significantly impedes their lengthy wearing comfort and functionality. Herein, inspired by the… read more here.

DOI: 10.1016/j.jmrt.2021.08.102
Abstract: Abstract Nature-inspired gradients can be implemented in metallic materials to achieve a synergy of strength and ductility. However, due to the small (often microscale) size of the gradient structured samples, their fracture properties have remained… read more here.
