Biocorrosion behavior of biodegradable nanocomposite fibers coated layer-by-layer on AM50 magnesium implant
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. …"

Functionalization of silica-coated magnetic nanoparticles as powerful demulsifier to recover oil from oil-in-water emulsion
منشور في 2021"…This study presents an innovative approach for the preparation of Fe3O4 nanoparticles covered with SiO2 shell (denoted as Fe–Si-MNP), which were used to recover oil recovery from oil-in-water emulsion (O/W-emul). The Fe–Si-MNP were prepared with differing silica layer thicknesses (5 nm [Fe–Si-1], 8 nm [Fe–Si-2], 10 nm [Fe–Si-3], and 15 nm [Fe–Si-4]) and tested for the percentage of oil separation (%Soil) under different dosages (DMNP), oil concentration (Doil), surfactant dosages (Dsur), and pH. …"
