    Biocorrosion behavior of biodegradable nanocomposite fibers coated layer-by-layer on AM50 magnesium implant حسب Abdal-hay, Abdalla

    منشور في 2016
    "…The corrosion performance of coated and uncoated coupon samples was investigated by means of electrochemical measurements. The results showed that the AJS 3D membrane fiber layers, particularly the hybrid membrane layers containing a small amount of nHA (3wt.%), induce a higher biocorrosion resistance and effectively decrease the initial degradation rate compared with the neat AM50 coupon samples. …"

    Curcumin a Colorimetric and Fluorimetric Cyanide Probe in Aqueous System and Living Cells حسب Hijji, Yousef

    منشور في 2019
    "…Cyanide causes a dramatic color change of the curcumin solution (acetonitrile : water 90 : 10) from bright yellow to dark orange. It causes dramatic spectral changes in the UV-vis spectrum of curcumin by the decrease in the absorption band intensity at 421 nm and a concomitant appearance of a strong band at 520 nm. …"
