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

Combining the Pitcher and Lotus Plant: Supericephobic and Superhydrophobic Silicone Films
Advanced Science, EarlyView.Based on bench‐top nanomolding of polydimethylsiloxane (PDMS) with optimized silicone oil content, we developed hierarchically structured silicone films by essentially combining the properties of the lotus and pitcher plant; particularly we are able to achieve water contact angle as high as 171° and ice adhesion strength as low as 11.5 kPa (i.e ...

Advanced Science, EarlyView.The unique lamellar structure of the eutectic alloy promotes selective oxidation of Al initially, while lattice distortion‐induced diffusion suppression slows oxide growth during steady state. Combining these strategies, a Multi‐Principal Element Alloy with excellent oxidation resistance at 1200℃ was designed.

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque
Advanced Science, EarlyView.In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...
