The Third‐Generation Magnetic Super‐Stable Mineralizer: Complete Removal and Separation of Multiple Heavy Metal Pollutants

open access: yesAdvanced Science, EarlyView.
The 3rd‐generation magnetic super‐stable mineralizer M‐MgAl‐700 features a core‐shell structure, strong superparamagnetism, large surface area, and abundant oxygen defects. It achieves exceptional Cd(II) and As(V) mineralization capacities, reducing both pollutants in co‐contaminated water and soil to meet national standards.

Grain Boundary‐Driven Lattice Dynamics in a Solid‐State Li‐Ion Conductor

open access: yesAdvanced Science, EarlyView.
Grain boundaries in Li3OCl${\rm Li}_3{\rm OCl}$ are shown to significantly alter its lattice dynamics and induce Li‐ion vibrational hardening and anion softening. These changes hinder ion transport while promoting electronic conductivity and instability.

Zero Thermal Expansion and Local Structure in KxMnxFe2‐xMo3O12‐Based Materials

open access: yesAdvanced Science, EarlyView.
Local structure engineering via ion insertion drives local structural transformation from low‐symmetry P21/a to high‐symmetry R‐3c, enhancing structural flexibility and realizing a transition from positive thermal expansion to wide‐temperature‐range zero thermal expansion in KxMnxFe2‐xMo3O12‐based materials.

Microstructure Optimization of Na3SbS4/Na3Zr2Si2PO12 Composite Solid Electrolytes for Improving Cycling Stability in All‐Solid‐State Sodium Batteries

open access: yesAdvanced Science, EarlyView.
This research demonstrates that incorporating 10 wt.% NASICON‐type Na3Zr2Si2PO12 into Na3SbS4 sulfide electrolytes mitigates interfacial instability and structural defects. The resulting composite enhances ionic conductivity to 3.97 * 10−4 S cm−1 and reduces activation energy.

Reaction‐Induced Reversible Reconstruction Enhanced Ni‐MgO/CaO Dual Functional Material for Stable CO2 Capture and In Situ Conversion

open access: yesAdvanced Science, EarlyView.
A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...
