Abstract ：
A green anion exchange membrane for electrodialysis desalination was synthesized using a solvent-free photo-polymerization approach. Vinylbenzyl chloride (monomer), tripropylene glycol diacrylate (crosslinker), and photoinitiator were mixed and subjected to UV polymerization for 20 min to create the base membrane, followed by positive charge modification with 1-methylimidazole. This method avoids organic solvents, offering economic and environmental benefits. By adjusting the degrees of crosslinking and positive charge, precise control over the membrane's microstructure and properties was achieved. The optimized membrane showed an area resistance of 1.67 Ω cm2 and a transport number of 0.956, demonstrating exceptional electrochemical performance. Under comparable conditions, the optimized membrane improved the NaCl removal rate by 11.47 %, increased current efficiency by 10.61 %, and reduced energy consumption by 16.75 % compared to commercial AMV membrane, highlighting its potential for scalable seawater desalination through electrodialysis. © 2024 Elsevier B.V.

Abstract ：
According to the hydration size and charge property of separated ions, the transport channel can be constructed to achieve precision ion separation, but the ion geometry as a separation parameter to design the channel structure is rarely reported. Herein, a reverse-selective anion separation membrane composed of a metal-organic frameworks (MOFs) layer with a charged “hourglass” channel as an ion-selective switch to manipulate oxoanion transport is developed. The gate in “hourglass” with tetrahedral geometry similar to the oxoanion (such as SO2- 4, Cr 2O2- 7, and MnO- 4) boosts the transmission effect oxoanion much larger than Cl− through geometric matching and Coulomb interaction. Specific channel structure exhibits an abnormal selectivity for SO2- 4/Cl− of 20, Cr 2O2- 7/Cl− of 6.6, and MnO- 4/Cl− of 4.0 in a binary-ion system. The transfer behavior of SO2- 4 in the channel revealed by molecular dynamics simulation and density functional theory calculation further indicates the mechanism of the abnormal separation performance. The universality of the membrane structure is validated by the formation of different nitrogen-containing modified layers, which also achieves in situ growth of the MOFs layer, and exhibits similar reversal separation performance. The geometric configuration control of ion transport channels presents a novel effective strategy to realize the precise separation of target ions. © 2024 Wiley-VCH GmbH.

Abstract ：
Under the environmental sustainability concept, landfill leachate concentrate can be up-cycled as a useful resource. Practical strategy for effective management of landfill leachate concentrate is to recover the existing humate as fertil-izer purpose for plant growth. Herein, we designed an electro-neutral nanofiltration membrane to separate the humate and inorganic salts for achieving a sufficient humate recovery from leachate concentrate. The electro-neutral nanofiltration membrane yielded a high retention of humate (96.54 %) with an extremely low salt rejection (3.47 %), tremendously outperforming the state-of-the-art nanofiltration membranes and exhibiting superior promise in fractionation of humate and inorganic salts. With implementation of the pressure-driven concentration process, the electro-neutral nanoltration membrane enriched the humate from 1756 to 51,466 mg & BULL;L-1 at a fold of 32.6, enabling 90.0 % humate recovery and 96.4 % desalination efciency from landll leachate concentrate. Furthermore, the recovered humate not only exerted no phytotoxicity, but also signicantly promoted the metabolism of red bean plants, serving as an effective green fertilizer. The study provides a conceptual and technical platform using high-performance electro-neutral nanoltration membranes to extract the humate as a promising nutrient for fertilizer application, in view of sustainable landll leachate concentrate treatment.

Abstract ：
Achieving a balance between flame retardancy and overall performance in epoxy resin (EP) continues to be a significant challenge. In this study, a new multi-DOPO-based reactive flame retardant (DZH) was synthesized successfully using a simple one-pot method and employed as a co-curing agent with DDM. The results indicated that the inclusion of DZH decreased the activation energy of the curing reaction system. Furthermore, the presence of DZH, with its remarkable charring ability, enhanced the formation of char residues under high temperature conditions. Notably, the flame retardancy and mechanical properties of the EP/DZH system were significantly enhanced at certain additions. When added at only 5 wt% (phosphorus content: 0.525 wt%), the LOI value of the EP/DZH-5 increased from 24.4 % to 35.3 % for the EP matrix and achieved a V-0 rating in accordance with UL-94. Meanwhile, EP/DZH-5 exhibited a reduction of 44.1 % in pHRR and 24.3 % in SPR. The superior flame retardancy of the EP/DZH system was attributed to the dual flame-retardant mechanism exhibited in both the gaseous and condensed phases. In addition, the abundant presence of rigid phosphaphenanthrene groups and 7C-7C interactions between benzene rings led to an improvement in the tensile strength and tensile modulus, which rose to 91.0 MPa and 1.76 GPa, respectively, from 79.5 MPa and 1.26 GPa of EP in the case of EP/DZH-3. The utilization of this flame retardant, based on multi-DOPO, offers a promising approach for the development of high-performance epoxy resins.

Abstract ：
Fouling control is the most critical concern in the implementation of nanofiltration (NF) for dye wastewater treatment. In this study, integration of NF and Fenton-like advanced oxidation was realized by tailoring a thin film composite NF membrane (TFNi) with in situ synthesized PDA/MnO2 interlayer. TFNi was optimized by controlling the amount of MnO2 nanoparticles incorporated within the interlayer which endowed the membrane with self-cleaning property. Besides it improved the membrane surface hydrophilicity and optimized the water transport path, resulting in alleviated fouling risks and an enhanced water permeance of 24 +/- 2 L m- 2 h-1 bar-1 compared to the control membrane. Fouling and subsequent chemical cleaning experiments were carried out on TFNi under various water chemistry conditions to elucidate the underlying mechanisms governing the self-cleaning properties. Accordingly, a high flux recovery ratio (FRR) (above 95%) was maintained thanks to the generation of free radicals by MnO2-H2O2 system which was validated by determining the free radical scav-enging activities. Moreover, the interlayer confined radicals can facilitate the decomposition of foulants on TFNi. Conclusively, H2O2-initiated self-cleaning of TFNi can be of great prospect for the efficient treatment of dye wastewater via in-situ generated free radicals.

Abstract ：
Smart healthcare sensors (SHSs) belong to a kind of patient-centered diagnostics, which highly revolutionizes traditional healthcare service and attracts great attention. However, widespread application of currently -reported SHSs is severely limited due to their non-ideal mechanical/electrical self-healing performance, too robust/weak skin-adhesion strength, and poor water resistance. A kind of novel film-based SHSs that composed of poly(3-hexylthiophene-2, 5-diyl)/butyl rubber (P3HT/BR), eutectic Gallium-Indium (E-GaIn), and polydimethylsiloxane-P3HT/BR (P-P3HT/BR) were proposed herein and employed for high-performance elec-trocardiogram (ECG) monitoring. Specifically, viscosity characteristic and low glass transition temperature of BR, hooked chains of P3HT, and encapsulated E-GaIn jointly endowed the SHSs with high mechanical and electrical self-healing efficiencies of 79.62% & PLUSMN; 5.60% and 94.49% & PLUSMN; 5.05%, respectively. Meanwhile, skin adhesion mechanism of the SHSs was mainly relied on Van der Waals force and friction force, thus resulting in a sufficient adhesion or painless detachment with a skin-adhesion strength of 7.00 & PLUSMN; 0.70 kPa. More interestingly, extensive experimental results performed in pigs and humans demonstrated the SHSs achieved ECG monitoring with high accuracy and stable sensitivity underwater, due to the designed hydrophilic/hydrophobic Janus surface. Overall, the as-fabricated SHSs provided an outstanding biopotential monitoring and paved an ascendant way toward personalized healthcare in the new era.

Abstract ：
Diffusion dialysis (DD) has high economic competitiveness for acid recovery; however, the fabrication of highly acid-permeable and salt-rejecting anion exchange membranes (AEMs) for DD is still a grand challenge. This paper presents in-situ cross-linked porous AEMs with tunable microstructures and high DD performance. The AEMs were fabricated based on chloromethyl polyethersulfone substrate using N, N, N ', N '', N ''-pentamethyldiethylenetriamine as a bifunctional agent for cross-linking and quaternization. The prepared porous AEMs showed significantly superior DD performance over conventional dense AEMs due to the high free volume and cross-linked networks within our membranes. The acid dialysis coefficient (UH+) and acid/salt separation factor (S) of the optimal AEM were 2.6 and 255.4 times as high as those of the commercial DF-120 AEM, respectively. Therefore, our low-cost, high-performance in-situ cross-linked porous AEMs may pave the way for large-scale acid recovery applications.

Abstract ：
Reverse osmosis (RO) has been recognized as a reliable technique for wastewater reclamation. To enhance its rejection of trace organic contaminants (TrOCs), a novel strategy was proposed to improve reverse osmosis (RO) membranes by fabricating thin-film nanocomposite membrane (TFNi) with a TA-Fe3+/CNTs interlayer. The TFNi-30 membrane was obtained by optimizing the loading capacity. This optimized membrane gave rise to an enhanced water permeance of 3.2 +/- 0.2 L m-2 h-1 bar-1, which was two times higher than that of the control membrane (1.1 +/- 0.2 L m-2 h-1 bar-1), while achieving a considerably higher rejection of inorganic salts and trace organic contaminants (TrOCs) thanks to the formation of a denser polyamide rejection layer. In addition, the specific roles of the interlayer structure in determining the separation performance of RO membranes were investigated by tailoring the support-free RO membranes and comparing them with the conventional mem-branes. This study would provide a peer reference for designing high performance RO membranes for wastewater reclamation via the TFNi strategy.
