DOI: 10.1016/j.cjche.2018.09.029

Abstract: Abstract In this study, a quantitative performance of three commercial polyamide nanofiltration (NF) membranes (i.e., NF, NF90, and NF270) for phosphorus removal under different feed conditions was investigated. The experiments were conducted at different feed… read more here.

DOI: 10.1016/j.memsci.2019.117386

Abstract: Abstract High performance membranes circumventing the global water scarcity are emerging from exquisite nanofabrication but the materials preparation complexity and permeability stability remain challenges. We report here that both the permeability and antibacterial property of… read more here.

DOI: 10.1016/j.memsci.2020.117971

Abstract: Abstract Intercalated structure and electrosprayed interfacial polymerization methods have recently been proposed for permeability enhancement of polyamide membranes. In this study, a Span 80 intercalated polyamide nanofiltration membrane was fabricated through electrospray for simultaneously improving… read more here.

DOI: 10.1016/j.memsci.2020.118910

Abstract: Abstract Machine learning overfitting caused by data scarcity greatly limits the application of chemical artificial intelligence in membrane materials. As the original data for thin film polyamide nanofiltration membranes is limited, here we propose to… read more here.

DOI: 10.1039/c7ra11632b

Abstract: A novel high-flux sulfonated polyamide nanofiltration (NF) hollow fiber membrane was made from the mixed monomers of 2,2′-benzidinedisulfonic acid (BDSA) and piperazine (PIP). By optimizing the preparation parameters (TMC concentration, reaction time and BDSA/PIP mixing… read more here.
