Summary: The global popularity of membrane separation is growing due to its high energy efficiency, small footprint, low capital, and operating cost, and especially its environmentally friendly process flexibility. However, the achieved membrane separation efficiency is still far from the potential value predicted by material simulation mostly due to the existence of undesirable membrane imperfections and defects. This review presents the recent opportunities and challenges in polycrystalline membrane fabrication, emphasizing the issue of unfavorable defect formation. State-of-the-art solutions and strategies for mitigating defects have been reviewed and evaluated in detail.

Summary: Adsorptive separation is crucial in various industries, but the requirements for adsorbents differ during adsorption and desorption processes. To address this challenge, the development of process-oriented smart adsorbents (POSAs) that dynamically adjust pore structures and surface properties is essential for enhancing efficiency in adsorption and desorption simultaneously.

Summary: In this study, dual-sulfonated polysulfone/metal-organic framework composite membranes were designed as proton exchange membranes. The membranes showed improved proton conductivity and dimensional stability due to the incorporation of sulfonated MOFs and the controllable sulfonation degree of the polysulfone matrix. The composite membranes exhibited high proton conductivity and moderate swelling ratio, even at high temperatures and humidity levels.

Summary: Nowadays, nanofiltration is widely used for various water treatment purposes, including softening, disinfection, and removal of heavy metal ions. This study developed new sustainable porous membranes and supported membranes modified with Zn-based metal-organic frameworks to enhance the efficiency of nanofiltration for heavy metal ion removal. The membranes were characterized using various techniques, and their performance was tested in the filtration of model and real mixtures. The modification with Zn-based MOFs improved the transport properties of the membranes due to their porous structure, hydrophilic properties, and different particle shapes.

Summary: The study focused on synthesizing polyMOF ligands featuring MOF-forming benzenedicarboxylic acid linkers using common radical polymerization techniques: reversible addition fragmentation chain transfer (RAFT) polymerization and free radical polymerization (FRP). It was found that high-dispersity ligands prepared through FRP formed crystalline polyMOFs, while low-dispersity ligands prepared through RAFT required additional H(2)bdc to yield crystalline materials similar to MOF-5 and UiO-66. This work suggests that ligand dispersity is a key factor for polyMOF synthesis and presents new possibilities for developing polymer-MOF hybrids based on radical polymerization.

Summary: Metal-organic frameworks (MOFs) are efficient carriers for controlled drug delivery due to their large surface area and adjustable pore size. A new approach called Pore Space Partition (PSP) was used to effectively encapsulate and pH-controlled co-delivery of two guest molecules. ZIF-8's pore space was partitioned by encapsulating the large molecule ursolic acid (UA), and the remaining space was filled with the small molecule 5-fluorouracil (5-FU). This approach resulted in a high loading capacity of UA (12.80 wt %) and 5-FU (11.20 wt %) in the 5-FU&UA@ZIF-8. This smart carrier exhibited pH-controlled delivery of UA and surprisingly showed pH-responsive delivery of 5-FU after pore space partition. The co-delivery of 5-FU and UA demonstrated excellent anticancer performance against 4T1 cells.

Summary: Metal-organic framework (MOF)-based membranes have been extensively studied as separators for lithium-sulfur (Li-S) batteries. This research investigates the property-performance relationship between MOF-based separators and Li-S batteries by adjusting the electrical conductivity, thickness, and mass loading of the MOF-based composite. The study found that the electrical conductivity of the MOF composite layer is more important than the physical/chemical trapping ability of polysulfides when the thickness is fixed. However, the trapping ability of MOFs becomes indispensable at smaller thickness, indicating the synergetic effects of the adsorption and conversion capabilities of the thin composite layer. This work highlights the importance of a holistic design consideration for MOF-based membranes in long-life and high-energy-density Li-S batteries.

Summary: The synthesized Cu-THQ MOF showed structural stability and enhanced hydrophilicity when incorporated into polyamide layers, leading to TFN membranes that broke the permeability-selectivity tradeoff by increasing water permeance and slightly enhancing salt rejection. Through different chemical and morphological characterizations, the underlying mechanism was probed, and the membranes also demonstrated improved tolerance to chlorine oxidation. With their excellent stability, the Cu-THQ MOF-based membranes further showed impressive performance in organic solvent nanofiltration involving dimethylformamide.
