Advanced Materials, EarlyView.A Cu/Ag‐Cu bilayer tandem catalyst is designed for a pyramid‐structured p‐Si photocathode, creating multiple and functionally distinct interfaces tailored to specific reaction steps and intermediate stabilization. This Cu/Ag‐Cu‐decorated p‐Si photocathode exhibits both high photocurrent and good selectivity for photoelectrochemical CO2 reduction to CH4.

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms
Advanced Robotics Research, EarlyView.A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.
