Microfluidic Gratings for X‐Ray Phase Contrast Imaging

Advanced Science, EarlyView.
This work establishes a new protocol for the fabrication of X‐ray gratings that exploits the advantages of microfluidics and enables a more inexpensive, faster, and scalable production process. These X‐ray devices are fundamental for implementing X‐ray phase contrast imaging (XPCI) in laboratory and clinical settings, yet their costly and complex ...

Rapid Cooling After Device Annealing Suppresses Interface Losses in Cu2ZnSnS4 Solar Cells Enabling High Efficiency and Stability

Advanced Science, EarlyView.
Rapid cooling after device annealing regulates the CdS/CZTS heterojunction and Mo/CZTS back contact, suppressing interfacial recombination and modifying the interfacial MoS2 layer, thereby enabling a 15.9% indoor PCE in pure‐sulfide CZTS solar cells.

Programmable Information Processing With Reconfigurable Self‐Contact Variable Stiffness Mechanical Metamaterial

Advanced Science, EarlyView.
Reconfigurable self‐contact variable stiffness metamaterials based on shape memory polymers enable programmable stiffness switching. Static arrays store and encrypt information with immunity to electromagnetic interference, while asymmetric stiffness converts symmetric vibration into directional matter transport.

Upadacitinib Restrains the Pathogenic Fitness of CD4+ T Cells and Aberrant B Cell Programming in Optic Neuritis

Advanced Science, EarlyView.
Single‐cell profiling and functional perturbation reveal coordinated JAK1‐pSTAT3 downstream programs in optic neuritis, including MCL1‐dependent fitness of pathogenic CD4+ Tem cells and glycolysis‐linked, cholesterol‐sensitive B‐cell responses associated with RORA. Upadacitinib disrupts this reciprocal T‐B‐cell circuit and alleviates neuroinflammation,

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range

Advanced Electronic Materials, EarlyView.
A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

Influence of Top Electrode Metal on Resistive Switching in Multilayer MOCVD MoS2 Memristors

Advanced Electronic Materials, EarlyView.
MoS2 memristors typically use evaporated noble metal electrodes. This study compares Pd, Ni, and Al electrodes and sputtered versus evaporated deposition. Pd is passive, while Ni damages MoS2, yielding poor switching. Sputtered Al enables reproducible ECM‐type switching with 95% yield, whereas evaporated Al forms an interfacial oxide that suppresses ...

Anion‐Cation Synergistic Passivation for High‐Performance FA‐Cs Halide Perovskite Photodetectors

Advanced Electronic Materials, EarlyView.
An anion‐cation synergistic passivation strategy is developed to improve perovskite photodetectors. Surface‐localized DMePDA2+ cations and bulk‐diffused Cl− anions simultaneously reduce defects, enhancing charge transport and suppressing recombination.
