Deformable Eutectic Alloy With Near‐Theoretical Yield Strength via Hierarchical Nanoscale Multiphases and Sessile Defects

Advanced Science, EarlyView.
A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...

Programmable Pentamolecular Cross‐Scale Imaging Reveals the Multiplicative Synergistic Effect of High‐Fat / High‐Salt Diet on Atherosclerosis

Advanced Science, EarlyView.
This study demonstrates multifactorial lifestyle impacts on the pathogenesis and progression of cardiovascular diseases by a nanofluorescence sensor array for detecting four redox species and protein phosphorylation levels. Through cross‐scale fluorescence imaging of rats with different diets, we revealed that compared with single dietary interventions,

Atomically Precise Clusterzymes: A Programmable Optoelectronic Platform for Neuroscience

Advanced Science, EarlyView.
Atomically precise clusterzymes, engineered via atomic and ligand design, serve as programmable platforms for neuroscience applications. They demonstrate tailored biocatalysis for neuroinflammation, tunable optical properties for deep‐tissue bioimaging and 3D visualization, and enhanced charge transfer for brain–computer interfaces.

Reprogramming M2b Macrophages via GPX1 Activation by Selenium Nanoparticles Attenuates Lupus Nephritis

Advanced Science, EarlyView.
SeZM NPs selectively target M2b macrophages through mannose–MRC1 (CD206) recognition, enhance GPX1 biosynthesis, and suppress mitochondrial ROS generation, oxidative stress, and JAK–STAT signaling. This dual regulation reduces pro‐inflammatory cytokine release, limits immune cell infiltration and fibrosis, and preserves renal function, providing a ...

Vacuum Arc Ion Flux From Vacuum Interrupter Contact Gap

PLASMA PHYSICS AND TECHNOLOGY, 2017
Dielectric properties of vacuum interrupters are influenced by metal vapour deposition on the inner ceramic surfaces. Therefore these surfaces are partly protected by shield electrodes. The metal vapour originates from the vacuum arc in the contact gap during switching off process.

Beyond Sabatier: Multiplicate Spillover Phenomena for Manipulating Catalytic Dynamics in Various Electrocatalysis

Advanced Science, EarlyView.
Various spillover‐mediated electrocatalytic reactions, such as hydrogen and oxygen evolution, carbon dioxide and nitrogen reduction, and methanol oxidization reactions, are systematically summarized. Abstract Spillover phenomenon, which is characterized by the dynamic migration of active species across catalyst surfaces, provides a promising avenue to ...

Multimodal AI‐Driven Identification of Dehydrocostus Lactone as a Potent Renal Fibrosis Attenuator Targeting IQGAP1

Advanced Science, EarlyView.
Renal fibrosis, a hallmark of CKD, lacks effective treatments. Herein, we developed a multimodal AI model (TCM‐SPred) to identify anti‐fibrotic agents and found that dehydrocostus lactone (DCL) targets IQGAP1 to inhibit Wnt signaling, blocking the interaction between IQGAP1 and CCT3, demonstrating potent anti‐fibrotic activity in vitro and in vivo ...
