Summary: The study introduces the SDE-A model for describing the salt permeability of reverse osmosis membranes. The model uses a small number of parameters to characterize the membrane's response to feedwater salinity and acidity. Comparison with the SF model shows a typical difference in computed salt permeability of less than 20%. The SDE-A model can accurately describe the effect of salinity and pH for membranes with different charge behaviors.

Summary: The removal of per- and poly-fluoroalkyl substances (PFASs) from water using membrane-based techniques has garnered increasing attention worldwide due to the widespread presence and high toxicity of these compounds. Different membrane technologies, such as direct filtration, adsorption-based membranes, and hybrid processes, have been developed to address the risk of exposure to PFASs and their environmental dispersion. The performance, treatment efficiencies, and mechanisms of these membrane processes for PFASs removal are analyzed, with a focus on the advantages, limitations, challenges, and prospects of applying these technologies in a practical and sustainable manner.

Summary: Increasing population and industrial development have led to a global freshwater shortage crisis. Desalination, particularly membrane-based desalination technology, has proven to be an effective solution. However, the current membranes used in desalination face challenges such as low permeation, low selectivity, wetting, and internal polarization. Therefore, researchers are exploring more advanced membranes, and electrospun nanofibrous membranes (ENMs) show promise due to their versatility and ability to address these membrane challenges. In this review, we discuss the application of ENMs in different membrane desalination processes and propose future directions for the development of advanced membranes.

Summary: Many commercial nanofiltrations (NF) and reverse osmosis (RO) membranes were evaluated for their efficiency in removing phthalates from water sources. It was found that the NF3 membrane showed the best performance in removing phthalates regardless of pH, due to its surface properties and appropriate pore size. Additionally, the NF3 membrane exhibited higher water flux compared to the RO membranes. However, further research is needed to investigate the effects of other compounds on membrane performance.

Summary: This study presents a new approach for the synthesis of water-dispersible core-shell nanocatalysts using metal-organic frameworks (MOFs). By introducing functionalized nanoclusters during the self-assembly of MOFs, missing-linker deficiencies are induced to fabricate mesoporosity. The resulting nanocatalysts significantly reduce the energy consumption of CO2 capture and achieve a 10-fold improvement in efficiency compared to conventional catalysts.

Summary: This study investigated the performance of glassy perfluoropolymers Cytop(R) and poly(50%PBVE-co-50%PDD) for carbon dioxide capture in raw natural gas. The presence of impurities, such as water vapor and toluene, affected the sorption isotherms and permeability of the membranes to CO2 and CH4. Liquid glycol carryover had no impact on Cytop(R) membranes, but slightly decreased the CO2/CH4 separation factor of poly(50%PBVE-co-50%PDD).

Summary: This study investigates the compatibility of high-density polyethylene (HDPE) plastic piping and two elastomer materials, poly(styrene-co-butadiene) (SBR) and poly(acrylonitrile-co-butadiene) (NBR), with ammonia and dimethyl ether (DME) as hydrogen carrier fuels. The results show that the elastomers have higher solubility and permeability for both fuels compared to HDPE, and DME has a significant impact on the intrinsic properties of HDPE and the elastomers, leading to material deterioration. Therefore, while HDPE pipelines can transport ammonia, it is not feasible for DME transportation.

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.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.
