Electrocatalytic CO2 Reduction over Sn‐Cu Bimetallic Catalysts Synthesized via an Amalgamated Lithium Metal Method

open access: yesAdvanced Science, EarlyView.
An amalgamated lithium metal method enables systematic control of Sn–Cu active‐site dimensions from isolated atoms to nanocrystallites. Increasing the metal loading shifts CO2 electroreduction selectivity from acetaldehyde on highly dispersed Sn–Cu sites to formate on Sn‐rich crystallites, revealing how bimetallic dispersion and local coordination ...

From Fluoride Removal to Interfacial Reactivity Enhancement: Functionalized La3+‐Crosslinked B/CuO Energetic Microspheres

open access: yesAdvanced Science, EarlyView.
A fluoride adsorption‐functionalization strategy directly couples fluoride wastewater remediation with combustion performance enhancement of B/CuO energetic microspheres. Fluoride captured from wastewater is retained within the microspheres without adsorbent regeneration or disposal, simultaneously achieving pollutant removal and enhanced energetic ...

Giant Direct Magnetoelectric Effect in Nanocomposite CoFe2O4:PVDF‐TrFE Thin Films

open access: yesAdvanced Science, EarlyView.
A novel three‐step grow‐etch‐fill fabrication approach creates structured cobalt ferrite/ferroelectric polymer nanocomposites with high interfacial areas. Driven by efficient strain‐mediated coupling, this crystalline system achieves a giant room‐temperature magnetoelectric coefficient nearly two orders of magnitude higher than other CFO/PVDF‐TrFE thin

Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

A Closed‐Loop Direct Recycling Process for Prussian White From Scrap and End‐of‐Life Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A closed‐loop direct recycling route for Prussian White sodium‐ion battery cathodes is demonstrated. Ice‐stripped scrap and end‐of‐life electrodes are regenerated via low‐temperature aqueous resodiation (80°C), restoring sodium content, Fe2+ redox chemistry, and structural integrity.
