Advanced Science, EarlyView.Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Advanced Science, EarlyView.Faster phenol photolysis at the air–water interface arises from two cooperative factors: a more favorable initial microenvironment for solvent‐side electron stabilization, which lowers CI access, and a more labile hydrogen‐bond network, which more readily reorganizes to stabilize the dark‐state intermediate.

(Fe4N/GaN)@GC: A Bifunctional Electrocatalyst for High‐Performance Rechargeable Zinc‐Air Batteries
Advanced Science, EarlyView.This work demonstrates that an unprecedented Fe4N/GaN heterostructure, stabilized by a graphitized carbon shell, induces interfacial charge redistribution and optimizes oxygen‐intermediate adsorption, enabling highly efficient bifunctional ORR/OER electrocatalysis for rechargeable zinc‐air batteries.

Limitations of Flexural Crack Width in Simply Supported One-Way Ribbed Slab [PDF]
The important consideration in design of multistory concrete buildings is reducing self-weight of the slabs. The system of one-way ribbed slab is one of the many systems chosen in order to reduce self-weight.

Adaptive Cu Reconstruction in Heterostructure Drives High‐Rate Nitrate‐to‐Ammonia Conversion
Advanced Science, EarlyView.An adaptively reconstructed Cu/CoOX heterojunction, featuring a surface‐localized, hydroxyl‐rich oxidized Cu species, forms in situ from a CuO/CoOX (Co1Cu9OX) pre‐catalyst during electrochemical nitrate reduction. The self‐adaptive reconstruction and the incorporation of heterostructure regulate nitrogen‐containing intermediate adsorption and *H supply,

Shear capacity of voided flat slabs: Influence of void height, slab thickness, and shear span
Results in EngineeringVoided flat slabs, a specialized form of conventional solid flat slabs, incorporate void formers in minimally contributing strength areas. While this method reduces concrete volume and offers advantages, it raises significant concerns regarding shear ...

Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking
Advanced Science, EarlyView.The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...
