Tracking the Dynamic and Interactive Metal Oxidation Changes in CoFe, CoNi, and NiFe Bimetallic Hydroxides for Electrocatalytic Oxygen Evolution

Advanced Functional Materials, EarlyView.
Operando hard X‐ray absorption spectroscopy is applied to track the dynamic and interactive metal oxidation changes in iron group bimetallic hydroxides under different chemical and electrochemical conditions. It shows that Co and Fe oxidation are relatively equal and synchronized in CoFeOxHy.

Growth of Millimeter‐Sized BaTaO2N Single Crystals by an NH3‐Assisted BaCl2 Flux Method

Advanced Functional Materials, EarlyView.
Millimeter‐sized BaTaO2N single crystals are successfully grown from a BaCl2 flux under NH3 flow. Their comprehensive characterization, including dielectric properties, is demonstrated, and the possible growth mechanisms are discussed. Abstract Perovskite‐type oxynitrides have attracted considerable attention due to their excellent photocatalytic ...

Spin glass states in multicomponent layered perovskites

Scientific Reports
AbstractTemperature-dependent dc-magnetization and ac-susceptibility curves have been recorded for series of single and double layered Ruddlesden-Popper multicomponent perovskites with chemical formula A2BO4 and A3B2O7, respectively, with (La, Sr) on A-sites and up to 7 different cations on the B-sites (Ti, Cr, Mn, Fe, Co, Ni, Cu). The phase purity and

Reducing Open‐Circuit Voltage Losses in Wide‐Bandgap FAPbBr3 Perovskite Solar Cells for Continuous Unassisted Light‐Driven Water Splitting

Advanced Functional Materials, EarlyView.
The combination of formamidinium thiocyanate and 1,3‐propane diammonium iodide for bulk and top‐surface passivation, and a ternary fullerene blend to improve energy band alignment, suppresses energy losses in wide‐bandgap FAPbBr3 perovskite solar cells.

High‐Entropy Perovskite Nanofibers for Bifunctional Air Electrodes in Reversible Protonic Ceramic Electrochemical Cells

Advanced Functional Materials, EarlyView.
High‐entropy perovskite nanofibers serve as robust and active bifunctional air electrodes in reversible protonic ceramic electrochemical cells. Their compositional complexity stabilizes the lattice, enriches oxygen vacancies, and accelerates surface exchange.

Wafer‐Scale Synthesis of Mithrene and its Application in UV Photodetectors

Advanced Functional Materials, EarlyView.
A controlled tarnishing step on the silver surface precedes the solid‐vapor‐phase chemical transformation into silver phenylselenolate thin films. The approach yields crystals exceeding 1 µm with improved in‐plane orientation. Integration on graphene phototransistors demonstrates high photoresponsivity, positioning mithrene as a promising material for ...
