Summary: The enhanced dye-sensitized BiPO4/BiOCl heterojunction system showed high photo-degradation activity for treating highly concentrated hazardous pollutants under visible-light irradiation. The efficient treatment was attributed to the high-performance sensitization of RhB and suitable conduction band match between BiPO4 and BiOCl in the P-BOC heterojunctions.

Summary: This article presents the synthesis of cerium oxide (CeO2) nanoparticles using a sol-gel method, followed by their decoration on multi-walled carbon nanotubes (CNTs) and graphene oxide (GO) to create binary and ternary hybrid nanocomposites via ultrasonic treatment. The presence of oxygen vacancy defects enhances the photocatalytic efficiency as observed using X-ray photoelectron spectroscopy (XPS). The ternary hybrid nanocomposites (CeO2/CNT/GO) exhibit excellent photocatalytic efficiency with a degradation rate of rose bengal (RB) dye up to 96.9% in 50 minutes. CNTs and GO facilitate interfacial charge transfer, thereby reducing electron-hole pair recombination. These findings suggest that these composites show great promise for the degradation of harmful organic pollutants in wastewater treatment.

Summary: In this study, a copper and bismuth co-doped CeO2 nanostructure was synthesized using subcritical hydrothermal method for water remediation application. The co-doping of copper and bismuth synergistically improved the conductivity and light-harvesting capabilities of the co-doped CeO2, as confirmed through current-voltage and optical studies. The microstructural, compositional, and morphological information of the photocatalyst were analyzed using powder XRD and spectroscopic techniques. The as-prepared co-doped CeO2-based photocatalyst demonstrated efficient mineralization of the anionic dye methyl orange under solar irradiation, outperforming a CeO2 photocatalyst in terms of effectiveness and rate of dye mineralization. The co-doped CeO2 photocatalyst also exhibited excellent robustness and retained its photocatalytic activity after multiple reusability tests.

Summary: Co-Ag granular films were grown using electrodeposition technique. The effective deposition conditions (e.g., current density) allowed for the enhancement of giant magnetoresistance (GMR) in the films. The films exhibited granular nature with regular and uniform magnetic domains. Increasing the current density decreased the particle size of Co and increased the magnetoresistance.

Summary: This study investigates the magnetic behavior of dextran-coated magnetite nanoparticles (DM NPs) with different sizes. The decrease in saturation magnetization (M-s) with decreasing particle size is modeled by considering a magnetically dead layer on the particle surface. The study also takes into account the contribution of dipolar interactions due to the formation of chain-like clusters of MNPs in the estimation of effective magnetic anisotropy (K-eff) values.
