Summary: This work investigates the structural, morphological, and photocatalytic properties of titanium dioxide (TiO2) and TiO2:NiIn (T-NiIn) coatings fabricated by spin coating. The results show that T-NiIn coatings exhibit higher effectiveness in the degradation of eosin-yellowish (EY) dye under both UV irradiation and solar light, and also show better stability after multiple cycles of reuse. The incorporation of nickel (Ni) and indium (In) in TiO2 coatings offers a feasible strategy to enhance the degradation of EY dye in drinking water.

Summary: In this study, a simple chemical synthesis method was used to prepare polypyrrole/silver/graphene (Ppy/Ag/Gr) ternary nanocomposites with varying concentrations of graphene. The interaction between polypyrrole, silver, and graphene was studied using XRD, FTIR, and UV-Vis spectroscopies. The results showed that the addition of the optimum concentration of graphene into Ppy/Ag enhanced its photocatalytic property. Furthermore, it was confirmed that the enhancement of photocatalysis in the Ppy/Ag/Gr sample was due to the increased surface area.

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.
