    High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling by Cabibbo, Marcello

    Published 2014
    “…The main problem with steel, isthat itexhibits a relatively low hardness (below 10 GPa) which strongly decreases upon annealing above about 600 K.Thus, the majority of modern tools are nowadays coated with hard coatings that increase the hardness, decrease the coefficient of friction and protect the tools against oxidation. …”

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

    Published 2021
    “…Pt/MgO nanoparticles were cuboid and in the nanosize range of 30–50 nm. 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). …”
