Summary: This study successfully prepared magnetically separable CoFe2O4-ZnO hybrid nanostructures and characterized their structure and morphology using various techniques. CoFe2O4-ZnO exhibited significantly enhanced photocatalytic performance compared to pristine CoFe2O4 due to its high light utilization ability and heterojunction formation that delayed charge carrier recombination. The study provides an efficient solution for sunlight-responsive magnetically separable CoFe2O4-ZnO photocatalyst in wastewater purification.

Summary: In this study, the synthesis of zinc oxide nanoparticles (ZnONPs) was investigated using a multiscale modeling approach based on a three-stage reaction mechanism via the hydrothermal method. The reactivity of chemical compounds in the reaction mechanism was evaluated using Density Functional Theory (DFT) with the B3LYP/6-311+G method. Computational simulations and numerical solutions were employed to replicate the three-dimensional morphologies of ZnONPs, such as rods, spheres, octahedra, and others, reported experimentally.

Summary: This review discusses the recent advances in the synthesis approaches, fundamental properties, and photocatalytic activity of Cu3N nanostructures. The study found that the synthesis conditions play a crucial role in the shape and size control of Cu3N. Cu3N nanostructures exhibit a narrow bandgap and excellent optical properties, and the presence of Cu and N vacancies on the surface of the nanoparticles contributes to their photocatalytic dye-degradation potential. Additionally, combining plasmonic nanoparticles with other photocatalysts enhances the efficiency of Cu3N.

Summary: This study presents morphology-controlled remote epitaxy of ZnO micro- and nanostructure crystals on graphene-coated GaN substrate via hydrothermal growth. By changing additives in the wet chemical solution, diverse morphologies of ZnO can be grown from nanowire to microdisk. The direction of ZnO's hexagonal sidewall facet is found to be homogeneous over the entire growth area on the graphene-coated GaN substrate.

Summary: In this study, zinc oxide optical ceramics containing 0-2 wt% ytterbium were prepared, with Yb2O3 acting as an inhibitor for ZnO grain growth. The ceramics exhibit transmittance up to 60% in the visible region and their infrared transmission is determined by free charge carrier absorption. Additionally, under X-ray excitation, intense luminescence bands are observed in the blue and green regions, with Yb2O3 causing a redistribution of luminescence intensity and faster emission decay.

Summary: The hydrothermal method was used to create dilute magnetic semiconductor nanoparticles of Zn1-xCoxO (x = 0, 0.01, 0.05, 0.09). The effect of cobalt doping on the microstructure, morphological and optical properties of Zn1-xCoxO was studied. The results showed that cobalt doping decreased the crystallinity of ZnO, but had little influence on the shape of the nanoparticles. Doped samples exhibited ferromagnetic behavior above room temperature, with the best performance observed at a Co content of 0.05. Doped ZnO nanoparticles showed improved dielectric, electrical conductivity, and magnetic properties compared to pure ZnO.

Summary: This research focused on the preparation and characterization of a novel zinc oxide/cadmium tungstate (ZnO/CWO) nanocomposite using a simple chemical method. The nanocomposite exhibited strong light emission in the blue-green range and showed an excellent sensitivity under alpha irradiation, surpassing the individual components of pure ZnO or CWO. Structural analysis through FESEM, TEM, XRD, XPS, and EDX confirmed a uniform distribution of spherical nanoparticles with characteristic peaks of ZnO, CWO, and related elements, while Fourier transform infrared spectroscopy revealed the presence of various functional groups. Overall, the optical quality of the ZnO/CWO nanocomposite was found to be improved compared with pure ZnO and CWO, showcasing its potential for radiation detection and optoelectronic device applications.

Summary: In this study, the synthesis of ZnO films by chemical bath deposition with the assistance of zinc chloride as an additive was investigated. The films were characterized using various techniques, and the results showed that by changing the concentration of zinc chloride, ZnO films with different preferential growth orientations can be obtained, which exhibit good optical transmittance and different visible emissions. It was also found that the concentration of Cl- can affect the defects and preferred orientations of the ZnO films.
