Advanced Functional Materials, EarlyView.The study explores structural and magnetic properties of one of the most recent topological quantum materials (MnBi2Te4). The Mn‐poor structure leads to stacking faults (quintuple layer ‐ QL of Bi2Te3 formation instead of a septuple layer ‐ SL of MnBi2Te4), resulting in a coexistence between weak antiferromagnetism and ferromagnetism.

In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device
Advanced Functional Materials, EarlyView.In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

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 ...

Electrochemical Formation of BiVO4/BiPO4 Photoanodes for Enhanced Selectivity toward H2O2 Generation
Advanced Functional Materials, EarlyView.In acidic KPi, V dissolves from the BiVO4 lattice, while adsorbed phosphate reacts with the electrode under an external bias, forming a BiPO4 surface layer. This BiPO4 layer exhibits stronger bicarbonate adsorption, redirecting the water oxidation pathway toward two‐electron H2O2 production.

Market responses to geopolitical risk and economic policy uncertainty: Evidence from Vietnam
HeliyonThe Vietnamese stock market has traditionally been affected by local factors. However, little attention has been given to the role of external shocks, such as the geopolitical risk (GPR) and economic policy uncertainty (EPU), from Vietnam's major trade ...

OIL PRICE VOLATILITY AND INFRASTRUCTURAL GROWTH: EVIDENCE FROM AN OIL- DEPENDENT ECONOMY [PDF]
Oradea Journal of Business and Economics, 2019 Since the discovery of crude oil in Nigeria in 1957, the Nigerian economy has remained a mono-product economy largely impacted by the effects of oil price volatility with its attendant adverse consequences on the nation’s revenue profile and ...
