Ammonia Gas Sensor Fabricated by Multifunctional ZnO/GO Nanocomposites for Long‐Term, Self‐Powered Monitoring

Advanced Science, EarlyView.
Zinc oxide/graphene oxide (ZnO/GO) nanocomposites serve as a gas‐sensitive film for ammonia sensing and as high‐performance electrode materials in supercapacitors, simultaneously. A wearable contact‐separated triboelectric nanogenerator is designed to directly drive the ZnO/GO nanocomposites‐based ammonia sensor.

Wafer‐Scale Room‐Temperature Processing of Lead‐Free Perovskites for Optoelectronic Applications

Advanced Science, EarlyView.
We present the first wafer‐scale, room‐temperature synthesis of lead‐free Cs3Sb2X9 (X = Br, I) perovskite films via solvent‐free magnetron sputtering. The resulting high‐performance photodetectors achieve benchmark responsivity, bandwidth, and detectivity, enabling scalable manufacturing for next‐generation optoelectronics.

Multifunctional Programmable Transmissive Metasurface with Phase and Amplitude Manipulation Capability

Advanced Science, EarlyView.
This work provides a multifunctional programmable transmissive metasurface with phase and amplitude manipulation capability in the sub‐6G band. By applying different coding strategies, the proposed metasurface can realize vortex beam generation, holographic imaging under phase coding mode, and multi‐beam forming in phase‐amplitude joint coding mode ...
