Summary: Suitable incorporation of Zn2+ ions into CsPbBr3 quantum dots enhances luminescence efficiency and chemical stability, as well as modifies the emission bands. This study successfully introduced high content Zn2+ ions into CsPbBr3 quantum dots, resulting in a new intense blue emission and green emission, depending on the ZnBr2/PbBr2 precursor ratio. The analysis confirmed the formation of CsZnxPb1-xBr3 alloyed quantum dots with different Zn alloy compositions.

Summary: Magnetoelectric composites were synthesized using PEG400 and characterized for their microstructure and magnetic properties. The composites exhibited ferrimagnetic behavior with variable saturation magnetization and coercivities. Impedance spectroscopy revealed a decrease in relative permittivities with increasing frequency and CoFe2O4 fraction. The magnetoelectric coefficient showed a dependence on both the CoFe2O4 fraction and sintering temperature, with a maximum value observed at x = 0.3. The frequency dependence of the coefficient was also investigated.

Summary: In recent years, researchers have focused on developing cobalt-containing composites as highly active heterogeneous catalysts for persulfate. While most studies have reported the leaching of cobalt ions during the catalytic degradation of organic pollutants, only a few have considered the contribution of dissolved cobalt ions to the degradation process. A study published in the Journal of Hazardous Materials investigated the synthesis, application, and catalytic mechanisms of cobalt-doped hydroxyapatite (Co-HAP) for the degradation of Rhodamine B (RhB). The study found that non-main catalytic mechanisms were listed and that the effect of Co-HAP was overestimated.

Summary: The combination of polymer blends and nanofillers is an effective strategy for creating high-performance polymer alloys. In this study, a one-pot synthesized polyvinyl acetate-modified cellulose nanocrystal (CNCs-PVAc) powder was used to enhance the properties of a PLLA/PBAT blend for 3D filament. The presence of ungrafted PVAc homopolymer improved the dispersion of CNCs in the blend and resulted in an improvement in strength and toughness. Additionally, the nanocomposites showed excellent biodegradability, biocompatibility, and shape-memory properties.

Summary: Cu-based nanostructures with controlled morphological and structural properties were synthesized via a solvosonication process using graphene oxide nanosheets. The size range of Cu-BTC nanoparticles could be adjusted by varying the content of graphene oxide in the precursor solution. The antibacterial activity of Cu-BTC/graphene oxide nanocomposites is directly influenced by the structure and morphology of Cu-BTC nanoparticles, with the smallest nanoparticles showing the highest activity.

Summary: This work examines the impact of changes in filler material composition on the dielectric constant and thickness of the interfacial region in a nanoparticle composite. The authors use an electrostatic force microscopy (EFM) method to investigate the interfacial parameters' dependence on the filler material. Two types of filler materials, barium titanate (BaTiO3) and alumina (Al2O3), are used with epoxy resin as the host material. A 3-D finite element method (FEM) model is employed for simulations. It is found that changes in filler material alter the interface thickness and dielectric constant.

Summary: In this study, different Si-rich ZSM-5 catalysts with Fe species were prepared through one-pot synthesis and impregnation technique, and applied in heterogeneous electro-Fenton (HEF) for the removal of methylene blue (MB). The results showed that the catalysts possessed well crystalline framework, high surface area, mesopore structure, and uniform distribution of Fe species. The optimal operating conditions for the [Fe]-ZSM-5 catalyst were pH = 4, applied current of 100 mA, and catalyst concentration of 0.1 g L-1, resulting in the highest MB removal (98%) in 15 min through the HEF process.

The magnetic study revealed that the crystal structure remained unchanged and the Co2+ ions exhibited high-spin with unquenched orbital angular momentum. The absence of magnetic ordering or spin freezing at low temperatures suggests the presence of finite-size or surface effects.

Summary: The impact of morphology and reducibility on lanthanum-doped ceria nanocatalysts for NO oxidation reaction was assessed in this study. Lanthanum-doped ceria with controlled morphology (nanocubes and nanorods) was prepared using a hydrothermal method. The structural, compositional, and redox characterization of these catalysts was performed using various techniques. The results revealed a synergistic effect between lanthanum and ceria, and the degree of enhancement depended on the morphology and the amount of lanthanum incorporated into CeO2. These findings can aid in optimizing ceria-based nanocatalysts for the removal of NOx emissions from exhaust gases.

Summary: The Gold Dust Defect on the surface of AISI 430 ferritic stainless steel is caused by improper recrystallization of the material, particularly during the hot-rolling step of the production process. The defect originates from the presence of martensite in the center of the material due to fast cooling during rolling, as well as the accumulation of chromium carbides separating unrecrystallized subgrains from the matrix. The defect becomes more pronounced after pickling, with the top-layer of subgrains semi-detaching from the surface and forming flakes that cannot recrystallize.
