Summary: In this study, polyamide (PA) thin-film composites (TFC) with embedded silver sulfide (Ag2S) nanoparticles (NPs) were fabricated as reverse osmosis (RO) membranes to mitigate fouling. The TFN membranes were prepared by interfacial polymerization on a polysulfone support membrane. The addition of varied amounts of Ag2S NPs (20, 30, and 50 mg) in the aqueous phase resulted in membranes with enhanced antifouling and permselectivity performance. The TFN membranes exhibited high pure water flux, salt rejection, and resistance to fouling.

Summary: Tuning the permeation properties of TFN membranes through molecular redesign is important for RO desalination performance above the trade-off limit. Activation by organic solvents can boost water permeability but has rejection loss constraints. This study innovatively integrated soluble organic macrocyclic cavitands in the activating solvent to form cavity-bearing nanocomposite structures, which improved water permeability and salt/boron rejection.

Summary: We have developed a threshold-responsive colorimetric system that allows a single sensor to repeatedly measure analytes. The system adjusts the sensor's exposure time and measurement frequency according to the sensor's response, preventing saturation and ensuring full regeneration before the next measurement. It also addresses issues with response time and detection range common to colorimetric sensors. Using this system, we successfully demonstrated continuous monitoring of ammonia and carbon dioxide gases for at least 60 detection cycles without degradation in sensor performance.

Summary: This study investigates the importance of graphene membrane in removing Mg and Ca ions and explores the influence of graphene doping and vacancy on the adsorption of these metal ions. It is found that B doping and vacancy creation enhance the adsorption of Ca ions, while N doping slightly decreases it. Therefore, the creation of nanopores or B doping in graphene can enhance the removal of Ca ions from aqueous solution.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.
