Multifunctional hybrid UF membrane from poly (ether sulfone) and quaternized polydopamine anchored reduced graphene oxide nanohybrid for water treatment
(Elsevier, 2021-12)In this study, a new quaternized polydopamine anchored reduced graphene oxide (QSiPD-rGO) nanohybrid was prepared through a one-step mussel-inspired tailoring of GO using a quaternized silica precursor and dopamine. The ... -
Nano-Brushes of alcohols grafted onto cellulose nanocrystals for reinforcing poly (Butylene succinate): Impact of Alcohol chain length on interfacial adhesion
(Multidisciplinary Digital Publishing Institute, 2020-01)Despite the many interesting properties of cellulose nanocrystals (CNCs), their hydrophilicity is one of the main challenges for their processing with hydrophobic polymers and matrices. To overcome this challenge, this ... -
Nanoporous hollow fiber polyethersulfone membranes for the removal of residual contaminants from treated wastewater effluent: Functional and molecular implications
(Elsevier, 2017-12)Hollow fiber membranes consisting of polyethersulfone (PES) reformed with high proportions of single bondOH, aryl-N and alkyl-F groups in nonsolvent additives were compared for the removal of residual Cr (VI), COD, and ... -
Networked cellulosic gel material as a pharmaceutical excipient
(Masdar Institute of Science and Technology, 2012)Networked cellulosic (NC) material was prepared in a gel form via sulfuric acid dissolution and hydrolysis of microcrystalline cellulose (MCC) and then regeneration in ethanol. The regenerated material was utilized ... -
