Eco-structured biosorptive removal of basic fuchsin using pistachio nutshells: A definitive screening design-based approach
El-Azazy M.; El-Shafie A.S.; Ashraf A.; Issa A.A. ( MDPI AG , 2019 , Article)Biosorptive removal of basic fuchsin (BF) from wastewater samples was achieved using the recycled agro-wastes of pistachio nut shells (PNS). Seven adsorbents were developed; raw shells (RPNS) and the thermally activated ... -
Electrospun PVDF graphene oxide composite fibre mats with tunable physical properties.
Issa, A.A.; Al-Maadeed, M.A.A.S.; Mrlik, M.; Luyt, A.S. ( Springer Verlag , 2016 , Article)This article is aimed at a basic physical characterization of electrospun PVDF/graphene oxide (GO) composite non-woven fibre mats.
