Unlocking Zenith Electronic State of Ni Sites in Ligand‐Engineered COFs for Efficient •O2−‐Driven Uranium Photoreduction

open access: yesAdvanced Science, EarlyView.
We develop a ligand engineering strategy to construct Ni‐diketimine‐linked COFs with precisely tuned Ni electronic states. By varying the coordinated diketone units, we achieve an optimal electronic configuration that enhances O2 adsorption and lowers the energy barrier for •O2− generation.

MN•CS•IO System: Cross‐Species Study for HBB Function in High‐Altitude Hypoxia Adaptation

open access: yesAdvanced Science, EarlyView.
We developed an integrative mesh‐nanorod sorting, chitosan nanoparticle delivery, and intraosseous injection (MN•CS•IO) system to investigate HBB in high‐altitude hypoxia adaptation. Transplanting Tibetan animals' HBB‐modified Lin‐ cells into mice achieved 95.59% transfection efficiency and 8.15% HBB expression. High‐altitude HBB recipients upregulated

PLOD1 Catalytic Activity Stabilizes ENO1 by Limiting FBXW7‐dependent Degradation to Promote Glycolysis and TMZ Resistance in Glioblastoma

open access: yesAdvanced Science, EarlyView.
PLOD1 interacts with ENO1 and limits its FBXW7‐dependent ubiquitination and proteasomal degradation through a mechanism requiring PLOD1 catalytic activity. ENO1 stabilization sustains glycolysis, promoting glioblastoma cell proliferation, migration, and temozolomide resistance.

Non‐Uniform Space‐Time‐Coding Modulation for Low‐Complexity Diagnostics of Reconfigurable Intelligent Surfaces

open access: yesAdvanced Electronic Materials, EarlyView.
A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.

Electrified Acetylene Removal From Ethylene Streams Enabled by Facet‐Engineered Cu–TiO2 Interfaces

open access: yesAngewandte Chemie, EarlyView.
Facet‐engineered interfaces enable selective electrochemical acetylene removal from ethylene streams. Dispersed Cu nanoclusters on the titania {001} facet suppress hydrogen and coupling byproducts, while stabilizing key hydrogenation intermediates.

Extension Economists: Valued in Mission, Penalized in Practice

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT As the public engagement arm of the land‐grant mission, we argue that Extension faculty in US agricultural economics departments face an identity crossroads as they struggle for institutional support. Specifically, we argue that Extension economists function as boundary‐spanning professionals within academic structures that often devalue ...
