This study employs longitudinal fluorescence imaging in transgenic mice to map post‐craniotomy cortical recovery. We identify distinct neuroimmune recovery phases: microglial structural inflammation peaks at ∼10 days, neuronal structural intensity peaks at ∼14 days and correlates with microglial activity, and functional network modularity is most ...

Active Force Dynamics in Red Blood Cells Under Non‐Invasive Optical Tweezers
A non‐invasive method combines low‐power optical tweezers with high‐speed microscopy to simultaneously monitor local membrane forces and displacements in single human red blood cells. This dual‐channel approach reveals a mechano‐dynamic signature that correlates the cell's metabolic state with its mechanical activity. This energetic framework serves as

Label‐Free Molecular Characterization of Protein Aggregates in Differentiated Astrocytes
Mid‐infrared photothermal microscopy enables label‐free structural, molecular, and functional imaging of protein aggregates in astrocyte cells. The processes of astrocytes differentiated on a nanomaterial interface are characterized by α‐helical signatures combined with enhanced interfacial thermal resistance properties, while the cell soma of non ...

Imperfection in Semiconductors Leading to High Performance Devices
Crystalline perfection is typically pursued in semiconductors to enhance device performance. However, through modeling and experimental work, we show that defects can be strategically employed in a specific detection regime to increase sensitivity to extreme values. GaN diodes are demonstrated to effectively detect high‐energy proton beams at fluxes as

Cryogenic cooling induces an orthorhombic‐to‐monoclinic phase transition in CsPbBr3 quantum dots, accompanied by pronounced strain localization at surfaces and interfaces. Multimodal in situ STEM directly visualize reversible defect healing during moderate cryogenic treatment and irreversible degradation upon prolonged exposure, revealing the intrinsic

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

A Scalable Method for Cavity‐Enhanced Solid‐State Quantum Sensors
Photoluminescent color centres in diamond and hexagon boron nitride are powerful nanoscale solid‐state quantum sensors. Methods for integrating them into macroscopic structures that improve their sensitivity are highly sought after. This study demonstrates a low‐cost and scalable method for the fabrication of quantum sensor‐doped thin‐film cavities ...
