Sub-4 nm Pt5Sm Intermetallic Catalyst toward Efficient and Durable Oxygen Reduction for Fuel Cell Applications

Abstract It is remarkably attractive but challenging to develop fine Pt–rare-earth intermetallic catalysts toward efficient and stable oxygen reduction reaction (ORR) for fuel cell applications. In this work, an amino-assisted method was employed to prepare the carbon-supported P...

Multilayered Uranyl-Containing Tungstophosphate with Two Different Dawson Units for the Photocatalytic Oxy-Thiocyanation of Alkynes

Abstract A novel multilayered uranyl-containing tungstophosphate, [H2N(CH3)2]13Na5[(UO2)2(W2O6)2(H2P2W15O54)(H2P2W14O52)]·15H2O (U2P4W33), has been successfully synthesized via an in situ assembly strategy. The compound was composed of three distinct building units, including one...

Effect of random corrosion pit dimensions on ultrasonic guided wave propagation characteristics in rock bolts

Rock bolts in complex underground environments are prone to randomly distributed localized corrosion damage, posing a severe threat to the stability of anchorage structures. Ultrasonic guided waves represent a core technology for nondestructive testing of bolt corrosion; however,...

Topology Engineering Regulates Free Volume to Decouple Efficiency‐Mechanical Performance Trade‐Off in Intrinsically Stretchable Organic Solar Cells

ABSTRACT Intrinsically stretchable organic solar cells (IS‐OSCs) hold great promise for wearable electronics, yet their development is severely hindered by the trade‐off between efficiency and mechanical robustness, remaining a critical challenge. Herein, three polymerized small‐...

A micro-CT-based “orientation–clustering–stiffness–damage” coupling framework for carbon-fiber/epoxy: From single-fiber scale to component-level failure prediction

A four-order “orientation-clustering-stiffness-damage” coupling framework is proposed for 28–30 vol% carbon-fiber/epoxy short-fiber composites (7 μm nominal fiber diameter, 3–5 mm chopped length), enabling accurate cross-scale failure prediction spanning from 60 μm single-fiber i...

HE-referenced eosinophil assessment and cutoff estimation using Congo red and Chromotrope 2R staining in chronic rhinosinusitis with nasal polyps

Abstract This cross-sectional histopathological study aimed to compare eosinophil visualization and quantification using Congo red, Chromotrope 2R, and conventional hematoxylin–eosin (HE) staining in chronic rhinosinusitis with nasal polyps (CRSwNP), and to explore HE-referenced...
