Summary: A comprehensive study of the magnetic properties of the Ising-like dipolar antiferromagnet DyScO3 reveals a crossover in magnetic dynamics at 10 K from Arrhenius-like regime to Quantum Tunneling of Magnetization (QTM), with antiferromagnetic ordering below 3.2 K in a GxAy-type magnetic structure. The low-temperature magnetization curves exhibit complex hysteretic behavior, with low-field anomalies related to metamagnetic transition and high-field hysteresis induced by strong magnetocaloric effect. Theoretical calculations considering dipolar interaction between Dy3+ moments reproduce key features of DyScO3's magnetic behavior, demonstrating rare characteristics of QTM and classical dipolar-induced magnetic order at the single-ion level.

Summary: Microstructure of Bi2O3-added WO3 ceramics was controlled by adjusting Bi/W atomic ratio and firing temperature. Higher power factors were observed in ceramics with larger WO3 grains due to higher electron carrier concentrations, resulting in higher figure of merit ZT values. The highest ZT value of 2.4 x 10-3 at 873 K was achieved for ceramics fired at 1223 K.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: Water is essential for the survival of living organisms, but industrialization has led to contamination of water sources with heavy metals and harmful pollutants. Magnetic nano ferrites have shown potential in effectively removing heavy metals from water due to their magnetic characteristics, high surface area, surface active sites, chemical stability, and ease of modification. This review explores recent literature on the synthesis and application of magnetic ferrites for removing heavy metals from water, aiming to provide a comprehensive understanding for future research.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
