Angewandte Chemie, EarlyView.Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...

Advanced Intelligent Systems, EarlyView.A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

Light‐Activated Isolation of High‐Quality Mitochondria for Therapeutic Transplantation
Angewandte Chemie, EarlyView.The Light‐Activated Mitochondrial Isolation (LAMI) platform enables the selective and non‐destructive isolation of high‐purity, metabolically active mitochondria. By integrating modular, ligand‐programmable magnetic probes with photo‐cleavable release, LAMI overcomes long‐standing limitations of conventional isolation methods and provides a robust ...

Advanced Intelligent Systems, EarlyView.Overview of the proposed Gate‐Align‐SED, including two stages of training: (1) Mean‐Teacher SSL Training; and (2) Enhancer Model Training. In complex real‐world environments such as disaster monitoring, effective sound event detection (SED) is often hindered by the presence of noise and limited labeled data.
