TL;DR: In this article, a new concept for the preparation of thin-film-composite (TFC) reverse osmosis (RO) membrane by interfacial polymerization on porous polysulfone (PS) support using novel additives is reported.

TL;DR: In this article, the effect of four processing variables on the final properties of ultrafiltration (UF) membranes was investigated, including the concentration of base polymer in the casting solution, solvent evaporation time, the addition of surface modifying macromolecules (SMMs), and the use of the additive polyvinylpyrrolidone (PVP).

TL;DR: In this paper, a hydrophiLic Surface Modifying Macromolecule (LSMM) was synthesized, characterized, and blended into the casting solution of polyethersulfone (PES) membranes.

TL;DR: Results indicate that the 17 kDa antigen (ovocleidin 17, OC-17) is secreted during shell formation and becomes incorporated into this structure, and may play a role in the crystallization process and influence the properties of the resulting eggshell.

TL;DR: In this article, surface modifying macromolecules (SMM) were synthesized and blended into the casting solution of poly(ether sulfone) and the solution was cast to films with thickness of 0.12 and 0.24 mm, which were placed in an oven with forced air circulation for periods of 3, 5, 7, and 2000 min to remove the solvent, before being immersed into water at 4 °C for gelation.
