Bioinspired Microreactor for Iodide Adsorption and Photooxidation Recovery

open access: yesAdvanced Science, EarlyView.
A bioinspired micro‐ionic‐reactor based on porous organic polymer (MIR‐POP) integrates rapid iodide capture with in situ photooxidative conversion, achieving record uptake capacity and high uptake efficiencies in simulated mining wastewater and natural brine. This bioinspired microreactor strategy offers a new avenue for sustainable iodine recovery and

Mitigating Electrochemical Isolation in Ni‐Rich Layered Cathodes for Durable Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
Electrochemical isolation of Ni‐rich layered cathodes in sulfide solid‐state batteries is uncovered as a previously unrecognized but critical performance‐limiting pathway. This study elucidates its origin and impact and introduces a scalable mitigation strategy using oxygen‐functionalized conductive carbon.

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 ...

Fe/N‐Doped Carbon with Nearly Ordered Mesopores and Tunable Particle Sizes as Model Catalysts for Quantitative Evaluation of Electrocatalytic Active Sites

open access: yesAdvanced Science, EarlyView.
This study is dedicated to the design and synthesis of MOF‐derived mesoporous Fe/N‐doped carbons as model catalysts, aiming to quantitatively evaluate the utilization of active sites in the ORR. Through modulation followed by pyrolysis, we successfully prepare size‐tunable Fe/MNC‐x with doped iron atoms and mesoporous structures. The smaller Fe/MNC‐250

Addressing Oxygen Embrittlement in Additively Manufactured Titanium via Cu‐Mediated Interstitial Site Engineering

open access: yesAdvanced Science, EarlyView.
A novel “Cu‐mediated interstitial site engineering” strategy is introduced to thermodynamically stabilize hexagonal oxygen (hex‐O) configurations in oxygen‐containing titanium alloys. The hex‐O configuration activates multiple slip systems and enhances dislocation pinning via long‐range repulsion.
