Advanced Science, EarlyView.Perovskite‐type oxide lanthanoid‐substituted BiCoO3 exhibits a reversible negative thermal expansion (NTE) originated from the coordination change from the CoO5 pyramid to the CoO6 octahedron due to melting of the dxy orbital ordering in the d6 electron configuration, and the 6.1% volume shrinkage in Bi0.82Nd0.18CoO3 is the largest ever observed in the

Advanced Science, EarlyView.An ultrafast (2‐minute), gas‐free chemical pre‐sodiation strategy using Na‐benzophenone is developed to compensate for initial sodium loss in calcium vanadate (CaV8O20). Driven by the Ca2+ ‘spectator effect’, the framework enables highly reversible, quasi‐zero‐strain solid‐solution sodium storage, explicitly bypassing destructive conversion reactions ...

Architecting Phase‐Selective Interlayers for Stable SiOx Lithium Storage via Dual‐Function Design
Advanced Science, EarlyView.Silicon anodes offer high capacity but suffer severe volume expansion. Silicon monoxide (SiO) buffers expansion, yet uncontrolled lithiation irreversibly consumes lithium as Li2O and oxygen‐rich silicates. Here, we design a layered SiOx featuring a phase‐selective conductive interfacial interlayer (PSCII), i.e., a Li4SiO4‐rich, ion‐accessible ...

Advanced Science, EarlyView.A polar dispersant, aromatic‐functionalized polyacrylate (AFPA), enables the formation of a uniform CBD network by enhancing miscibility with PVDF and suppressing phase separation. This leads to α‐phase crystallization of PVDF and aligned CNT networks within the CBD, resulting in well‐connected structures that improve cohesion, electron/ion transport ...

Insights Into the Nature of Quantum Emitters in Electron‐Irradiated Hexagonal Boron Nitride
Advanced Science, EarlyView.Hyperspectral imaging is used to identify quantum emitters hosted by the 2D material hexagonal boron nitride. By selecting specific emission wavelengths, one can distinguish individual emitters from ensembles and gain important insights into the atomic structure of these emitters.

Design Rules for Quantitative Control of Intragrain Planar Defects in Halide Perovskites
Advanced Science, EarlyView.Dose‐budgeted electron microscopy reveals the design rules governing intragrain planar defects in halide perovskites: {112}t ferroelastic twins proliferate with increasing tetragonality and grain size, whereas {111}c twins and stacking faults emerge as the lattice approaches cubic symmetry.
