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: 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.
