Micro(nano)plastics from synthetic oligomers persisting in Mediterranean seawater: Comprehensive NMR analysis, concerns and origins

The presence in seawater of low-molecular-weight polyethylene (PE) and polydimethylsiloxane (PDMS), synthetic polymers with high chemical resistance, has been demonstrated in this study for the first time by developing a novel methodology for their recovery and quantification from surface seawater. These synthetic polymer debris (SPD) with very low molecular weights and sizes in the nano-… Continue reading Micro(nano)plastics from synthetic oligomers persisting in Mediterranean seawater: Comprehensive NMR analysis, concerns and origins

Biofouling Mitigation Using Graphene Oxide Functionalized Polyethylenimine/Sulfonated Polysulfone Composite Membranes

Biofouling is a major concern in membrane filtration which could adversely have an effect on the overall membrane performance. To address this issue herein, we prepared polyethylenimine-grafted graphene oxide (GO-PEI) as a filler material to be used in the sulfonated polysulfone membrane (SPES). The PEI grafting on GO and successful sulfonation of PES was confirmed… Continue reading Biofouling Mitigation Using Graphene Oxide Functionalized Polyethylenimine/Sulfonated Polysulfone Composite Membranes
