Improved Deformability of Co‐Free Medium Entropy Oxides by Controlled Entropy Destabilization

open access: yesAdvanced Science, EarlyView.
Controlled entropy destabilization activates defect‐mediated plasticity in Co‐free (CuMgNiZn)O by promoting pre‐existing Cu‐rich secondary phases that serve as defect sources. Temperature‐dependent dislocation activity evolves from limited motion at room temperature to extensive glide and stacking‐fault formation at 600 °C, enabling improved plasticity

Interface Rectification via Roll‐to‐Roll Dual‐Confinement Nanocoatings for High‐Temperature Polymer Capacitors

open access: yesAdvanced Science, EarlyView.
Dual confinement in self‐assembled nanocoatings regulates polymer dynamics and hot‐carrier transport, enabling an interface‐rectification strategy for high‐temperature polymer capacitive energy storage. ABSTRACT Polymer film capacitors are indispensable for energy storage and power conversion, yet their energy density and efficiency deteriorate rapidly

p-GaN层厚度对GaN基p-i-n结构紫外探测器性能的影响

open access: yes, 2008
研究了p-GaN层厚度对GaN基pin结构紫外探测器性能的影响.模拟计算表明:较厚的p-GaN层会减小器件的量子效率,然而同时也会减小器件的暗电流,较薄的p-GaN层会增加器件的量子效率,但是同时也增加了器件的暗电流.进一步的分析表明,金属和p-GaN之间的结电场是出现这种现象的根本原因.在实际的器件设计中 ...

ZMIZ2–DUX4–LGR5 Signaling Axis Maintains Stemness Properties and Facilitates Docetaxel Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies ZMIZ2 as a therapeutic target for docetaxel‐resistant triple‐negative breast cancer, sustaining cancer stemness‐associated properties and docetaxel resistance. ZMIZ2 upregulation enhances DUX4‐mediated LGR5 activation through the SWI/SNF components BRG1 and BAF57.

Water‐Coupled Interfacial Modulation Enhances Photovoltaic and Pyroelectric Responses in Transparent Self‐Powered ZnO/NiO Photodetectors

open access: yesAdvanced Science, EarlyView.
Direct water contact enhances the performance of a transparent self‐powered FTO/ZnO/NiO/AgNW/ZnO UV photodetector. Reduced surface reflection improves optical transmission, while an electric double layer at the ZnO/water interface modulates interfacial electrostatics and promotes charge separation.
