Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy

open access: yesAdvanced Science, EarlyView.
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...

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

open access: yesAdvanced 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 ...

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

open access: yesAdvanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Targeted Mitochondrial ECSIT Overexpression Attenuates MASH by Increasing OTUD3 Expression

open access: yesAdvanced Science, EarlyView.
Mitochondrial ECSIT expression is reduced during MASH pathogenesis. Overexpression of mitochondrial ECSIT mitigates steatohepatitis and maintains hepatic metabolic homeostasis. Mechanistically, ECSIT enhances intramitochondrial OTUD3 expression to stabilize SIRT3 through deubiquitination, thus preserving mitochondrial function and impeding disease ...
