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 ...

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

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.

Heavy Prussian Blue Analog with Magnetic Ordering above 400 K

Advanced Science, EarlyView.
A cyanido‐bridged vanadium(II)–hexacyanomolybdate(III) Prussian Blue analog synthesized mechanochemically exhibits ferrimagnetic ordering above 400 K. SQUID magnetometry and XMCD experiments confirm antiparallel alignment of V and Mo moments. This establishes hexacyanomolybdate(III) as a robust precursor for high‐temperature molecule‐based magnets ...
