Broadband, Single‐Layered, and Optically Transparent Reflective Phase‐Shifting‐Surface Array for Beam Manipulation and Enhanced Wireless Communications

Advanced Electronic Materials, EarlyView.
A novel optically transparent reflectarray design approach based on multi‐resonant phase‐shifting elements with minimal fine metal line (FML) structures and low‐loss single‐layer cyclic olefin copolymer (COC) substrate is proposed. The design achieves exceptional antenna performance while ensuring high optical transparency, validated through wireless ...

Configuration and Charge Dynamics of Defect‐Cluster‐Dipoles in CaTiO3 for Enhanced Permittivity

Advanced Electronic Materials, EarlyView.
In La‐doped CaTiO3, the clustering of La ion and Ca vacancies is clearly observed and the configuration of such defect‐cluster is validated. Combining photoelctronic and dielectric spectroscopy enables the dielectric relaxation process with the charge transfer routes.

Screening and Development of Sacrificial Cathode Additives for Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
This work presents a computational screening approach to identify Li‐rich transition‐metal oxide sacrificial cathode additives and provides experimental validation of antifluorite‐structured Li6MnO4 as a potential candidate. Abstract This work presents a computational screening approach to identify Li‐rich transition‐metal oxide sacrificial cathode ...

Understanding the Metal‐Center Mediated Adsorption and Redox Mechanisms in a FeMn(NbTa)2O6 Columbite Material for Anion Exchange Membrane Water Electrolyzers

Advanced Energy Materials, EarlyView.
FeMn(NbTa)2O6‐columbite is a sustainable and high‐performance bifunctional electrocatalyst for anion exchange membrane water electrolyzers, comparable to benchmark catalysts. In situ XAS and DFT analysis show Fe/Mn sites exhibit higher OER activity due to reduced overpotentials and favorable O→OOH energetics. The Nb/Ta sites facilitate charge transfer,
