Liquid metal catalysts are widely assumed to promote high‐quality 2D growth. In this work, operando experiments and machine‐learning‐accelerated simulations show that hBN on Cu breaks this graphene‐derived expectation, where molten Cu promotes multilayer/3D growth, but re‐solidified single‐crystal Cu stabilizes monolayer formation.

Real‐Time Ferroelectric Domain Wall Dynamics During Electric Poling and Depoling
Real‐time visualization of domain wall dynamics during alternating‐current poling, direct‐current poling, and electrical depoling in relaxor‐PT ferroelectric single crystals reveals distinct field‐dependent pathways and strong path dependence. Instant polarized light microscopy uncovers reversible domain wall nucleation, motion, and reconfiguration ...

(Fe4N/GaN)@GC: A Bifunctional Electrocatalyst for High‐Performance Rechargeable Zinc‐Air Batteries
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.

Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking
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 ...

Cement-based materials often suffer reduced compressive strength due to internal porosity, yet the specific roles of pore size, shape, and spatial distribution remain inadequately quantified.

Gap‐Free Information Transfer in 4D‐STEM via Fusion of Complementary Scattering Channels
Fused Full‐Field STEM (FF‐STEM) is introduced as a 4D‐STEM imaging modality that combines direct ptychography with tilt‐corrected dark‐field reconstruction in a single acquisition. Fourier‐space fusion using Wiener‐type spectral weighting closes the low‐frequency contrast gap inherent to bright‐field methods, delivering gap‐free, dose‐efficient, near ...

Ocean state estimates that represent mesoscale and submesoscale dynamics are crucial for climate research and ocean forecasting. Accurate submesoscale representation in ocean models is a current challenge due to rapidly evolving flow and lack of ...

A flexible PDMS‐LATP polymer‐ceramic membrane creates lithium‐ion “superhighways” for rapid and selective extraction from complex brines. The amorphous PDMS matrix suppresses nonselective leakage and stabilizes the ceramic network, while LATP provides preferential Li+ conduction.

A supramolecular pyroptotic thermal switch encapsulates I3− within β‐cyclodextrin (β‐CD) and undergoes CaCO3 mineralization. Upon lysosomal acidification, CaCO3 is degraded, releasing Ca2+ and I3−. Concurrently, BODIPY activation converts I3− into I2, inducing oxidative stress and Ca2+ overload, which together trigger caspase‐3/GSDME‐mediated ...
