  • All-optical image processing using metasurfaces is advancing due to its high speed, integrability, and low energy consumption, yet background noise and clutter hinder the progress. In this work, a real-time optical image processor is introduced, using a metal-dielectric-metal film to perform spatial band-pass filtering in momentum space enabling high-resolution edge detection and real-time dynamic denoising.

  • Energy density and cyclability are often a trade-off for lithium-ion batteries. The authors develop cobalt- and nickel-free cathodes with both good cycling stability and high energy density through the integration of polyanion units into rocksalt structures.

  • In this study, bi-layered heterogeneous tetraphenylporphyrin-based COF membranes, consisting of negatively and positively charged monolayers, are fabricated using a two-step sequential self-assembly process followed by interfacial polymerization. By applying an electric field as the driving force, rectified ion transport is observed for the first time. Notably, this ionic current rectification can be modulated by adjusting the salt concentration and the structural composition of the membranes. Additionally, this phenomenon is found to be universal across various COF heterojunctions with different chemical constituents. These findings have important implications for the development of innovative nanofluidic materials and devices.
