Summary: Zinc oxide nanoparticles were successfully synthesized using glycine nitrate solution combustion synthesis. The synthesized nanoparticles exhibited a pure hexagonal wurtzite-like structure of ZnO. They showed effective visible light catalytic activity in the degradation of methylene blue dye, degrading 98% of the dye in 120 minutes with 0.1 g/L of catalyst loading. Photoluminescence studies suggested that the enhanced photocatalytic activity may be attributed to the presence of singly ionized oxygen vacancy or intrinsic defects.

Summary: In this work, Ag-doped ZnO nanoparticles were successfully synthesized by pulsed laser ablation of Ag-coated ZnO target in water. The ratio of Ag dopant in ZnO nanoparticles was found to strongly depend on the thickness of the Ag layer on the ZnO target. The synthesized nanoparticles were characterized using various techniques to determine their crystal structure, elemental composition, morphology and size distribution, mass concentration, and optical properties. Photocatalytic studies revealed that the ZnO nanoparticles doped with 0.32% silver showed the highest photodegradation rate of methylene blue under UV irradiation, indicating the significant doping effect on photocatalytic activity.

Summary: In this study, flower-like ZnO architectures assembled with nanorods were successfully synthesized using Thermionic Vacuum Arc in two operation modes. The morphology and uniformity of ZnO nanorods could be tuned by modifying the operation mode. The results showed that ZnO in the pulsed mode exhibited enhanced photocatalytic performance and better degradation efficiency for target contaminants compared to the direct current mode. The photocatalytic degradation of antibiotic molecules was confirmed by the agar-well diffusion assay, without the formation of secondary hazardous products.

Summary: Silver (I) oxide (Ag2O) nanoparticles (NPs) were synthesized by solution reduction. The Ag2O NPs were characterized using XRD, FTIR, SEM, DRS, and DLS techniques. The results showed the structure, shape, energy gap, and functional group variations of Ag2O NPs. The synthesized Ag2O NPs exhibited a mean hydrodynamic diameter of 171 +/- 82.8 nm in water. The photocatalytic activity of Ag2O NPs towards the degradation of Methylene blue (MB) dye under solar light was tested, and a maximum removal efficiency of 91.5% in 70 min was achieved. The photodegradation data followed pseudo-first-order kinetics with a rate constant of 0.0319 min(-1) and a half-life time of 21.72 min.

Summary: This study investigated the synthesis, characterization, and photocatalytic performance of zinc oxide/activated carbon fiber nanocomposites prepared by hydrothermal method. The nanocomposites exhibited excellent photocatalytic activity, with nearly 99% degradation of methylene blue in 2 hours under UV irradiation. The enhanced photocatalytic activities were attributed to the high surface area, enhanced UV-light absorption, and reduced charge carrier recombination resulting from the synergistic effect of adsorption and photocatalytic degradation of zinc oxide and activated carbon fiber.

Summary: In this study, LaxNi0.5Co0.5Fe2-xO4 nanoparticles were used as catalysts for Methylene Blue degradation. The nanoparticles were produced using the citrate-aided sol-gel auto-combustion method and exhibited homogeneous size distribution. The structural and optical characteristics of the nanoferrites were analyzed using X-ray diffraction and UV-visible reflectance spectroscopy respectively. Morphological and compositional studies were conducted using FESEM and EDX spectra, while BET analysis was used to determine the surface area. Raman Spectroscopy was employed to estimate the vibration parameters. The most efficient catalyst, La0.06Ni0.5Co0.5Fe1.94O4, achieved a 98.69% efficiency in 140 minutes. The use of La3+ substituted Ni0.5Co0.5Fe2O4 nanoferrites as catalysts offers advantages such as high recycling capability, stability, and simplicity of separation using an external magnet.

Summary: In this study, the anticancer efficacy of Ginsenoside Rh1 (G-Rh1) isolated from Korean Panax ginseng Meyer was investigated. G-Rh1 showed significant cytotoxicity against human lung adenocarcinoma (A549) and inhibited the mRNA expression of RhoA, ROCK1, MMP1, and MMP9 in cancer cells. The study suggests that the anticancer activity of G-Rh1 may be related to the induction of apoptosis via the RhoA/ROCK1 signaling pathway.
