Summary: Membrane technology has great potential in liquid waste treatment and resource recovery. However, the non-adjustable pore size of traditional membranes limits their selectivity for target ions. Covalent organic frameworks (COFs) have emerged as a promising candidate for advanced ion separation membranes due to their low density, large surface area, tunable channel structure, and tailored functionality. This review analyzes and summarizes the progress in understanding ion capture mechanisms, preparation processes, and applications of COF-based membranes, providing promising approaches for the design, preparation, and application of COF-based membranes in ion selectivity for recovery of ionic resources.

Summary: We investigated targeted and localized material modifications produced by electropulsing on Al-capped Nb microbridges. The affected areas showed a decrease in work function, but little morphological change was observed. The extent of the modified regions was strongly influenced by terminal geometry, and modeling estimated a threshold temperature of 435 +/- 35 K for inducing material modifications. These findings provide insights into subtle modifications and progress in nanofabrication techniques.

Summary: The unique sieving capability of nanofiltration (NF) technology has played an important role in water or organic solvent purification. Polyamide (PA) thin film composite (TFC) NF membranes (PA-TFC-NF) have dominated research and applications in NF technology due to easy manufacturing method and acceptable permeability/selectivity. However, non-polyamide NF membranes (NPA-NF) have also made great progress in terms of anti-fouling ability, durability, chemical stability, and extreme pH resistance. This review classifies NPA-NF membranes into six categories and discusses their fabrication mechanism, material performance, advantages and disadvantages, as well as current challenges and future prospects.

Summary: The structure and electronic properties of Br layers on Ag(111) at different coverage were investigated using low-temperature scanning tunnelling microscopy, scanning tunnelling spectroscopy, and density functional theory calculations. It was found that the Br layers form a hexagonal (√3×√3)R30° structure with a coverage of around 0.3 monolayer, and a striped (6)(-1)(1)(2) structure with a coverage of around 0.4 monolayer. The study also revealed suppressed differential conductance for both structures at certain voltages, indicating the usefulness of Br layers in reducing the coupling between Ag(111) electrons and adsorbates.

Summary: Polyester (PE) membranes have gained significant attention due to their remarkable chlorine resistance and antifouling ability. In this study, three relatively dense polyester membranes were successfully prepared using erythritol, xylitol, and isomalt as monomers, showing satisfying separation capacities and potential for applications in drinking water treatment. The study also revealed the influence of molecular size, hydroxyl density, and activity of polyols on the physicochemical properties and separation performance of PE membranes. The PE membranes outperformed commercial NF270 and lab-made polyamide membranes in terms of chlorine resistance and antifouling performance. This study provides valuable insights for the development of high-performance PE membranes through rational monomer selection and performance optimization.

Summary: This study found that a simple hexane treatment after the interfacial polymerization reaction can significantly alter the properties of polyamide (PA) thin-film composite (TFC) nanofiltration membranes and enhance their separation performance in drinking water treatment. The treatment time of hexane has a significant impact on the membrane properties, with 5 seconds of hexane rinsing leading to a thinner active layer and more than 60% improvement in water permeance. Hexane soaking for a longer time can effectively reduce the membrane surface negative charge density by approximately 70%. These property variations make the hexane-treated membranes more competitive than conventional PA membranes for hardness removal in drinking water treatment. Furthermore, the rejection performance for organic micropollutants can be maintained after hexane treatments of varying durations due to the unchanged membrane pore sizes.
