A mussel-inspired interlayer of polydopamine (PDA)/polyethylenimine (PEI) is codeposited on the ultrafiltration substrate to tune the interfacial polymerization of piperazine and trimesoyl chloride for the preparation of thin-film composite (TFC) nanofiltration membranes (NFMs). This hydrophilic interlayer results in an efficient adsorption of piperazine solution in the substrate pores. The sol...

The salivary film, denoted the pellicle, formed on oral surfaces is of great importance for oral health and comfort. The present study describes mechanically-assisted sodium dodecyl sulphate (SDS) elution of the in vivo pellicle formed on human enamel and visualisation of the desorbed pellicle proteins using two-dimensional gel electrophoresis (2-DE). To verify this removal of the pellicle, a c...

in this research, modification on the ultrafiltration (uf) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (fo) water treatment. two monomers, m-phenylenediamine (mpd) and trimesoyl chloride (tmc) with different concentrations of mpd (2.0% w/v and 1.0% w/v) were reacted with tmc (0.15% w/v) for interfacial polymerization (...

Abstract. The forward osmosis (FO) process has been considered for desalination as a competitive option with respect to the traditional reverse process. interfacial polymerization (IP) reaction between two monomers (i.e., m-phenylenediamine, MPD, and 1,3,5-benzenetricarbonyl chloride, TMC) is typically used prepare selective polyamide layer that prevents salts allows water molecules pass. In th...
