High‐Entropy Engineering to Stabilize Single‐Atom Ru Catalysts for Efficient and Durable Water Splitting

ABSTRACT Developing efficient and durable electrocatalysts for oxygen and hydrogen evolution reactions (OER/HER) remains fundamentally challenging due to the intrinsic trade‐off between activity and stability. We herein report a high‐entropy‐engineered strategy to stabilize singl...

Corrosion Behavior of Two Gd Particle-Doped Fe-Based Amorphous Coatings with Excellent Neutron Absorption Performance

Safe long-term storage of spent nuclear fuel requires materials that combine high neutron absorption with excellent corrosion resistance. In this study, two Gd-doped Fe-based amorphous coatings (2X5 + Gd and PC + Gd) containing 6.0 wt.% Gd were fabricated by high-velocity air–fue...

Decoupling the inverse κ – E g trade-off in 2D organic–inorganic magnetic semiconductors

Simultaneously achieving a high dielectric constant (κ) and a wide bandgap (Eg) in a single material remains challenging. Here, we report a charged-building-unit stacking strategy that yields tetragonal β-Fe3Se4-based organic–inorganic semiconductors. These materials exhibit both...

Bulk ferroelectric heterostructures

Interfaces in oxide heterostructures act as critical regions to induce emergent and novel types of functionality in thin films. Herein, we demonstrate the creation of bulk ferroelectric heterostructures (BFHs) in monolithic ferroelectrics by nanoscale elemental partitioning, unlo...

Hot Corrosion Behavior and Mechanism of Ru-Containing Ni-Based Single-Crystal Superalloy Exposed to Molten Na2SO4 at 950 °C

In this study, the hot corrosion behavior of a low-Cr, Ru-containing nickel-based single-crystal (SX) superalloy under exposure to Na2SO4 corrosive environments at 950 °C for up to 200 h was systematically investigated. The hot corrosion kinetics of the alloy exhibit a typical tw...

Machine learning empowered compositional design of multiple rare-earth principal component disilicates

Abstract The targeted design of multi-RE-principal-component RE2Si2O7 disilicates ((nRExi)2Si2O7) for environmental barrier coatings (EBCs) applications requires customizing the multi-RE compositions to achieve maximal optimization of the target properties. A critical prerequisit...
