Boosting the Performance of Epitaxial Perovskite Microstructures by Surface Passivation

Advanced Optical Materials, EarlyView.
Surface passivation is applied to epitaxial perovskite structures. Improvements are obtained in respect to luminescence intensity and decay time, as well in respect to photodetection and lasing. Highlight results include photoluminescence transients that are limited only by carrier diffusion and a record low laser threshold for microcrystal‐based ...

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

Advanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Continuous Physics‐Informed Learning Expedited Battery Mechanism Decoupling

Advanced Science, EarlyView.
A battery modeling framework combining dual neural networks with physical prior is presented to track internal mechanisms, decouple overpotential components, and early predict aging trajectories using only DC data, eliminating the need for additional measurements.

Free‐Standing Halogen‐Bonded Nanosheets Formed by Ultrasonic Liquid Exfoliation

Advanced Science, EarlyView.
Free‐standing nanosheets held together by halogen bonding interactions (XB), formed through ultrasonic liquid exfoliation of layered molecular crystals, are reported here for the first time. The work challenges the conventional requirement for strong in‐layer interactions for the formation of stable nanosheets through liquid exfoliation and establishes

Fresnel Magnetic Imaging of Ultrasmall Skyrmion Lattices

Advanced Science, EarlyView.
This study uncovers periodic contrast reversal in ultrasmall skyrmion lattice imaging through defocus‐modulated Fresnel magnetic microscopy, elucidating its origin in the sinusoidal contrast transfer function mechanism and providing fundamental insights into defocus‐mediated phase‐to‐intensity conversion processes in nanoscale magnetic imaging ...

A Programmable, 3D Neuron‐On‐Chip Platform Integrating Near Real‐Time Biosensing and Multiaxial Loading for Mechanobiological Injury Profiling

Advanced Science, EarlyView.
A programmable 3D Neuron‐Injury‐on‐a‐Chip platform integrates multiaxial mechanical loading with ultrasensitive electrochemical biosensing to decode neuronal responses in real time. By mimicking physiologically relevant extension–torsion forces, the system reveals load‐specific biomarker trajectories (T‐Tau, NFL), gene regulation, and apoptosis.

Spatially Resolved Mapping of Voltage‐Gated Proton Channel Activity Reveals Delayed Proton Transport in Local Microenvironments

Advanced Science, EarlyView.
A revolutionary imaging platform integrating quantitative single‐molecule photobleaching with ratiometric fluorescence probes enables high‐throughput (≈2300 individually resolvable channels) mapping of individual proton channels in a large field (≈3000 µm2), overcoming the spatial and temporal limitations of conventional electrophysiology.
