Toward Next‐Generation High‐Speed Communication and Imaging: Solution‐Processed Sb2(S,Se)3/CdS Heterojunction for Ultrafast Self‐Powered Photodetector

Advanced Science, EarlyView.
A high‐quality solution‐processed Sb2(S,Se)3/CdS heterojunction is designed to overcome the intrinsic limitations of conventional photodetectors. The fabricated device achieves an excellent self‐powered performance, including a high responsivity of 0.6 A W−1, an ultrahigh specific detectivity of 7.68 × 1012 Jones, and a wide 3db bandwidth of 175 kHz ...

Spin‐Selective Interface Engineering in Oxide–Ferromagnetic Junctions via Atomic‐Scale Oxygen Control

Advanced Science, EarlyView.
We show that interfacial oxygen at the MgO/Fe interface can be transformed from an uncontrolled variable into a tunable design parameter for spintronic junctions. Momentum microscopy provides direct access to the momentum‐ and spin‐resolved electronic structure beneath the insulating MgO layers, revealing how oxygen intercalation reshapes buried Fe ...

Surface Plasmon Enhanced Photoluminescence of Carbon Dots Formed In Situ on Silver Gratings

Advanced Science, EarlyView.
Carbon emitters formed in situ on a silver grating via plasmonic catalysis yield enhanced spontaneous emission by preferential radiative decay into surface plasmons. Enhancement manifests as emission exhibiting characteristics of coherence (polarization, directionality), and accelerated lifetimes of ∼30 ps, yielding Purcell factors of ∼70.

Photonuclear Population of 229m,gTh in Th‐Doped Crystals Toward Nuclear Clock Development

Advanced Science, EarlyView.
This study demonstrates a novel photonuclear approach for producing the nuclear clock isomer 229mTh in thorium‐doped crystals, overcoming current supply limitations. Through cross‐section calculations and Monte Carlo simulations, we identify optimal crystal materials and irradiation conditions, achieving high signal‐to‐noise ratios.

PEC‐DFM Hybrid‐Sensor Based on Nanoparticle‐Resolved Estimation for Sensitive and Reversible Glucose Monitoring

Advanced Science, EarlyView.
Abstract The accurate detection of glucose in wound exudate is critically important for monitoring chronic wound healing. While photoelectrochemical (PEC) sensors are widely used, they often suffer from material degradation caused by redox reactions during operation. Herein, we introduce a dark‐field microscopy (DFM) setup integrated with a PEC system,
