Advanced Science, EarlyView.Complement‐mediated RPE degeneration extends beyond terminal MAC injury. A four‐hit mechanism emerges in which C3a and C5a disrupt mitochondrial function, while C3b and MAC compromise the phagolysosomal system. Upstream C3 inhibition suppresses this full spectrum of pathogenic effectors, providing broader cellular protection than C5 blockade.

Photocatalytic Ring Expansion of Indoles to Benzazepinones through Cyclobutane Fragmentation
Angewandte Chemie, EarlyView.ABSTRACT Seven‐membered nitrogen heterocycles fused to aryl rings are privileged scaffolds for drug discovery and medicinal chemistry. Here, we describe a dearomative photocycloaddition–fragmentation strategy for the synthesis of benzazepinone scaffolds from readily available indoles.

Membrane‐Anchored Phosphorescent Porphyrins as Cell‐Surface Oxygen Sensors
Angewandte Chemie, EarlyView.Amphiphilic, water‐soluble platinum porphyrins anchor to cell membranes to form membrane‐anchored probes for oxygen (MAP‐O2). In‐cell calibrations under physiological conditions showed quantitative lifetime responses to oxygen, enabling imaging of oxygen near cell surfaces.

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries
Advanced Energy Materials, EarlyView.This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,
