      A magnetically guided slow positron beam is being constructed at Qatar University and is currently being optimised for regular operation. This is the first positron beam in the Middle East, as well as being the first Arabic ...

    • Morphology and property changes in PLA/PHBV blends as function of blend composition 

      Kanda G.S.; Al-Qaradawi I.; Luyt A.S. ( Springer Netherlands , 2018 , Article)
      PLA/PHBV blends were prepared by melt mixing. The morphology and physical properties of the blends and neat polymers were investigated. Scanning electron microscopy (SEM) studies provided evidence of interfacial cavities ...

    • Positron annihilation study on polyaniline nanocomposite used for Pb(II) ion removal 

      Al-Thani, N.J.; Bhadra, J.; Abdulmalik, D.; Al-Qaradawi, I.; Alashraf, A.; ... more authors ( Taylor & Francis , 2016 , Article)
      Nanocomposites of polyaniline (PANI) with three different concentrations of micrometre-sized sawdust are prepared in aqueous media via chemical casting method at room temperature. Thereafter, the removal efficiency of the ...
