Improved properties and salt rejection of polysulfone membrane by incorporation of hydrophilic cobalt-doped ZnO nanoparticles by Muneer M. Ba-Abbad (14151660)

“…<p dir="ltr">In this study, the nanoparticles (NPs) of ZnO and Co²⁺ ions doped ZnO (doped ZnO) were incorporated into a matrix of polysulfone (PSf) membranes to enhance their surface properties prepared using a simple wet phase inversion technique. The hybrid PSf membranes were fabricated with 0.5 wt. % of ZnO and doped ZnO NPs. …”

Oxidative stress cytotoxicity induced by platinum-doped magnesia nanoparticles in cancer cells by Mohamed Qasim, Al-Fahdawi

“…The cytotoxicity of Pt/MgO nanoparticles was determined via the 3-(4,5-dimethylthiazol-2-yl)−2,5-diphenyltetrazolium bromide assay on the human lung and colonic cancer cells (A549 and HT29 respectively) and normal human lung and colonic fibroblasts cells (MRC-5 and CCD-18Co repectively). …”
