Abstract The lithium dendrite issue is a major bottleneck that limits the utilization of metal anodes in high‐energy rechargeable batteries. From perspective nucleation mechanism, this work develops new type cation‐selective (CS) separator with anion immobilization behavior to boost anode.

Miniaturized spectrometers are of considerable interest for their portability. Most designs to date employ a photodetector array with distinct spectral responses or require elaborated integration micro & nano optic modules, typically centimeter-scale footprint. Here, we report design micron-sized near-infrared ultra-miniaturized spectrometer based on two-dimensional van der Waals heterostructure (2D-vdWH). By introducing heavy metal atoms delocalized electronic orbitals between 2D-vdWHs,...
Abstract Nickel oxide (NiO X ) has a crucial role in enhancing the efficiency and stability of p‐i‐n inverted perovskite solar cells (PSCs), which hold great potential for commercialization. However, improving contact passivation between perovskites NiO is challenge due to hindered buried interface.
