    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. …"

    Impact of moisture contents on the performance of organic bi-layer ITO/OD thermo-electric cells حسب Ahmad, Zubair

    منشور في 2016
    "…The experimental results clearly show that with the increase of temperature Seebeck coefficient increases, whereas with increasing moisture contents the Seebeck coefficient of the ITO/OD thermo-electric cell significantly decreases. Our results point out the need for well-controlled environmental conditions, predominantly moisture level, in order to appraise the thermo-electric performance of organic semiconductor materials. 2016, Springer Science+Business Media New York.…"
