Tuning the Optoelectronic Properties of Wide Bandgap Perovskites: Data‐Driven Insights from Combinatorial Synthesis and High‐Throughput Experimentation

Advanced Functional Materials, EarlyView.
Combinatorial vapor deposition enables independent tuning of Cs/Pb and Br/Cl in wide‐bandgap perovskites. Automated multimodal mapping of 500+ compositions reveals a high‐energy optical transition that correlates with enhanced photoluminescence, defining a practical Cs/Pb window.

A Thermodynamic Model of Antiferroelectics and Its Application to Electric Field Induced Antiferroelectric‐Ferroelectric Transition in PbZrO3

Advanced Functional Materials, EarlyView.
A thermodynamic model that incorporates ferroelectric, antiferroelectric, and antiferrodistortive orders of PbZrO3${\rm PbZrO}_3$ is established and parameterized based on experimental measurements and first‐principles calculations. We derive a Clapeyron‐like equation for describing the temperature‐dependence of critical electric fields for the ...

Boosting high-rate Li-ion storage properties by La(III) ion doping in spinel (Co0.2Cr0.2Fe0.2Mn0.2Ni0.2)3O4 high-entropy oxide anode

Journal of Advanced Ceramics
The present work aims to create lattice distortion and optimize the surface oxygen vacancy (OV) concentration in a model spinel (Co0.2Cr0.2Fe0.2Mn0.2Ni0.2)3O4 high-entropy oxide (HEO) through a heteroatom La3+ doping strategy.

Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

Advanced Functional Materials, EarlyView.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...

Unraveling the intrinsic origins of defect formation in V-based alloys during hydrogen sorption cycles: Nano-scale hierarchical structures induced by lattice distortion

Nano Research
The degradation of vanadium-based alloys during hydrogen sorption cycles is closely linked to defect accumulation (e.g., dislocation and lattice strain), yet the atomic-scale origins of such defects remain poorly understood.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Roles of elements V and N in tetragonally distorted Fe-Co-V-N films

Scientific Reports
Tetragonally distorted Fe-Co-V-N with a body-centred tetragonal (bct) structure has a high saturation magnetisation and a high magnetocrystalline anisotropy of ~ 1 MJ/m3 and is expected to be a new hard magnetic material.

High-entropy rare earth stannate ceramics: Acid corrosion resistant radiative cooling materials with high atmospheric transparency window emissivity and high near-infrared solar reflectivity

Journal of Advanced Ceramics
In response to the development of the concepts of “carbon neutrality” and “carbon peak”, it is critical to developing materials with high near-infrared (NIR) solar reflectivity and high emissivity in the atmospheric transparency window (ATW; 8–13 μm) to ...

Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl
