    Enhancement of mechanical and corrosion resistance properties of electrodeposited NiP-TiC composite coatings حسب Fayyaz O.

    منشور في 2021
    "…Vickers microhardness and nanoindentation results demonstrate the increase in the hardness with an increasing amount of TiC particles attaining its terminal value (593HV100) at the concentration of 1.5 g L−1. Further increase in the concentration of TiC particles results in a decrease in hardness, which can be ascribed to their accumulation in the Ni–P matrix. …"

    Differentiation of human olfactory bulb-derived neural stem cells toward oligodendrocyte. حسب Marei, Hany E

    منشور في 2018
    "…The differentiation medium, containing cAMP, PDGFA, T3, and all-trans-retinoic acid (ATRA), promotes OBNSCs to generate mostly oligodendrocytes (OLs) displaying morphological changes, and appearance of long cytoplasmic processes. OBNSCs showed, after 5 days in OLs differentiation medium, a considerable decrease in the number of nestin positive cells, which was associated with a concomitant increase of NG2 immunoreactive cells and few O4(+)-OPCs. …"
