    Bond durability of sand coated and ribbed basalt FRP bars embedded in high-strength concrete حسب Al-Hamrani, Abathar

    منشور في 2023
    "…Ribbed bars had significantly higher bond strength than sand-coated bars and were less affected by the surrounding environments. After 9 months, the bond strength retentions for sand-coated bars were 29.43, 63.93, and 67.43%, and 66.10, 94.94, and 80.44% for ribbed bars under the exposure to the 50 °C seawater, sulfuric acid, and freeze–thaw cycles, respectively. …"

    Production and investigation of flexible nanofibers of sPEEK/PVP loaded with RuO2 nanoparticles حسب Chamakh, Mariem

    منشور في 2021
    "…Scanning electron microscopy (SEM) demonstrated the successful fabrication of nanofibers with diameter range of 140-240 nm as well as nanoparticles with average sizes within the range of 6 nm and 9 nm. The effect of annealing and RuO2 addition was illustrated by the decrease in fibers diameter. …"
