Carbon‐Coated Moth‐Eye Structure: An Ultrabroadband THz‐DUV Near‐Perfect Absorber
Advanced Optical Materials, EarlyView.A silicon moth‐eye surface coated with pyrolytic carbon achieves >98% absorption from 1 to 1200 THz by combining gradient‐index matching with PyC's broadband conductivity, forming an ultra‐broadband absorber from THz to deep UV. Experimental results and simulations agreed well.

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation
Advanced Robotics Research, EarlyView.This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

Angewandte Chemie, EarlyView.Photochemical anaerobic oxidation of sulfides, using nitroarenes as bifunctional reagents, enables the formal manipulation of the C─S bond. The method allows direct and selective access to versatile carbonyl compounds from largely inert sulfides by C–H oxidation, thus avoiding multistep activation by sulfur oxidation.

Automated Iterative N─C and C─C Bond Formation
Angewandte Chemie, EarlyView.Automated iterative assembly of MIDA or TIDA boronate building blocks enables generalized and automated preparation of many different types of small functional molecules in a modular fashion. However, until now, this engine could not leverage nitrogen atoms as iteration handles, excluding molecules rich in N─C and C─C bonds.

A Wearable AI‐Driven Mask with Humidity‐Sensing Respiratory Microphone for Non‐Vocal Communication
Advanced Science, EarlyView.A wearable, plug‐and‐play respiratory microphone—featuring a gold nanoparticle‐based humidity sensor—facilitates voice‐free verbal communication for patients with impaired vocal fold function. Abstract Hoarseness and dysphonia caused by vocal cord conditions or laryngeal surgeries significantly hinder communication and quality of life.
