MXene‐Supported Single‐Atom Electrocatalysts

Advanced Science, EarlyView.
This review discusses the characteristics and synthesis of MXenes to elucidate their benefits as support materials. Next, methods and characterization for anchoring SAs onto MXene are discussed. Subsequently, a comprehensive discussion is provided on the recent applications of MXene‐supported SACs in electrocatalysis. Finally, the future challenges and

Mitigating Strain Localization via Stabilized Phase Boundaries for Strengthening Multi‐Principal Element Alloys

Advanced Science, EarlyView.
Strain localization along phase or grain boundaries leads to crack initiation typical of alloys. In multi‐principal element alloys, the enamel‐like microstructure is stabilized by phase boundaries. This facilitates trans‐phase migration of semi‐atomic surfaces and provides sufficient plastic space for dislocation‐mediated deformation.

Thermally Reconstructed Ru/La‐Co3O4 Nanosheets with Super Thermal Stability for Catalytic Combustion of Light Hydrocarbons: Induced Surface LaRuO3 Active Phase

Advanced Science, EarlyView.
The high‐temperature induced the exsolution of La from La‐Co3O4 lattice and facilitated the in situ formation of highly active LaRuO3 perovskite through a solid‐phase reaction with surface RuOx. This process significantly enhanced the thermal and hydrothermal stability of Ru/La‐Co3O4 for light hydrocarbons (LHs) oxidation, providing an innovative ...

High Radiation Resistance in the Binary W‐Ta System Through Small V Additions: A New Paradigm for Nuclear Fusion Materials

Advanced Science, EarlyView.
Refractory high‐entropy alloys exhibit superior radiation tolerance, but face fabrication challenges due to complex compositions. It is demonstrated that reducing the number of alloying elements does not compromise radiation resistance in a novel W‐Ta‐V highly‐concentrated refractory alloy.
