Abstract ：
Sustainable chemistry principles underscore the pivotal role of solvent-free processes in the fabrication of anion exchange membranes (AEMs). This study presents an eco-friendly, solvent-free approach for AEM preparation via photopolymerization, utilizing 4-vinylpyridine as the monomer and divinylbenzene as the crosslinking agent. The polymerization, conducted at ambient temperature and completed within 20 min, was followed by post-polymerization N-alkylation with ethyl bromide to introduce pyridinium groups. The precise modulation of crosslinking and N-alkylation levels enabled meticulous control over the membranes' intrinsic chemical properties and their functional effectiveness in electrodialysis desalination. The optimal membrane's area resistance was recorded at 1.09 Omega cm2, while its transport number reached 0.965, outperforming the commercial AMV AEM in desalination efficacy. This work underscores the promise of solvent-free photopolymerization as a sustainable, high-performance strategy for fabricating AEMs, providing substantial advancements in both environmental sustainability and electrodialysis desalination performance.

Abstract ：
Diffusion dialysis (DD) presents a highly promising and cost-efficient approach for acid recovery, yet its performance is often hindered by the acid permeability of anion exchange membranes (AEMs). To address this challenge, a one-step approach has been developed to fabricate porous AEMs. Using brominated polyphenylene oxide (BPPO) as the porous base membrane, imidazole is employed for in-situ crosslinking and cationization. This approach not only retains the inherent porosity (>63.5 %) of the base membrane but also achieves an exceptionally thin selective layer (<0.3 mu m), thereby creating abundant free space volume. Through a concurrent enhancement of ion transport sites and crosslinking density, the membrane effectively breaks acid permeability-selectivity trade-off. The optimal IPPO-20h AEM demonstrates a remarkable increase in both the acid dialysis coefficient (U-H+ = 34.1 x 10(-3) m/h) and separation factor (S-H+/(Fe)2+ = 573.8) in the HCl/FeCl2 system, with enhancements of 4- and 31-fold, respectively, compared to the commercial DF120 AEM, at 25 degrees C. This high-performance AEM, synthesized via a straightforward and mild process, offers significant potential for large-scale acid recovery applications.

Abstract ：
Dispersion of SiO2 particles in aqueous solutions using block copolymers remains challenging, particularly due to degradation in highly alkaline environments and difficulty in achieving high solid content. Herein, we report the synthesis of an anionic block copolymer, poly(glyceryl methacrylate-b-sodium p-styrenesulfonate) (PGGMA-b-PSSS), containing abundant hydroxyl groups, via reversible addition-fragmentation chain transfer (RAFT) polymerization of sodium p-styrenesulfonate and glycidyl methacrylate monomers. The hydroxyl groups in PGGMA-b-PSSS serve as anchoring points, producing a steric hindrance effect between SiO2 particles by interacting with silanol groups on the particle surface. Furthermore, electrostatic repulsion from the poly(sodium p-styrenesulfonate) block significantly enhances the dispersibility of PGGMA-b-PSSS in aqueous systems. A systematic investigation of the dispersibility of SiO2 particles was conducted under various compositions and concentrations of PGGMA-b-PSSS across a wide alkaline pH range. Our results show the effective dispersion of sub-micron and micron-sized SiO2 particles, achieving solid contents of up to 35 wt% over a wide pH range (3–13). © 2025 Elsevier B.V.

Abstract ：
It is a waste of gallium resource to discard the high aluminum-containing gallium electrolyte. The Ga/Al separation is difficult by only using lime precipitation because of high gallium loss rate. The present study employs an adsorption resin LSC-600P to recover gallium in the simulated gallium electrolyte and then uses lime to remove aluminum, leaving only alkali solution recycled. The results showed that the aluminum removal rate in the gallium electrolyte was 93.12% under the conditions of reaction temperature of 85 degrees C, addition of lime 2 times to the theoretical molar ratio of calcium to aluminum, reaction time of 3 h and stirring speed of 600 r/min. In the experiments of gallium adsorption, after six adsorption-desorption cycles, the adsorption rate of gallium by LSC-600P resin still reached 98.6%, and the adsorption rate of aluminum was lower than 4.5%. In the desorption process, the desorption rate of gallium was more than 98%, and the aluminum content in the stripping solution after desorption was almost negligible. The resin exhibits high adsorption affinity for gallium while demonstrating minimal adsorption for aluminum.

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. The metal-organic frameworks (MOFs) layer membrane with a charged "hourglass" gate exhibits high reverse-selectivity of oxoanion/Cl- ions and high flux of oxoanion. The free sulfate (F-SO2- 4) used to construct the gate utilizes the geometric matching and Coulomb interaction generated by its tetrahedral structure and charge to promote the transfer of oxoanions with similar geometric configurations. image

Abstract ：
Severe surface fouling of nanofiltration (NF) has hindered its practical implementation in treating dye-containing wastewater from the textile industry. To address this fouling issue, a novel thin-film nanocomposite NF membrane (TFNx) was proposed by embedding catalytic manganese dioxide (MnO2) nanoparticles within polyamide (PA) rejection layer to realize in situ Fenton-like advanced oxidation self-cleaning. The incorporation of MnO2 nanoparticles was validated to moderately reduce the degree of cross-linking of the PA layer, thereby obtaining an enhanced surface hydrophilicity. The inclusion of MnO2 nanoparticles increased the surface hydrophilicity, resulting in a higher water permeance (TFN10 18.1 +/- 0.7 L m(-2) h(-1) bar(-1)) that was 57.4% higher than that of the control thin film nanocomposite (TFC) membrane, while a high dye rejection was maintained. In addition, the presence of catalytically capable MnO2 nanoparticles in the Fenton-like reaction led to membrane self-cleaning and demonstrated a better antifouling behavior. The generation of free radicals was triggered by the addition of peroxymonosulfate (PMS). Furthermore, the impacts of operational conditions on membrane self-cleaning performance and operation stability were comprehensively investigated.

Abstract ：
Microfluidic synthesis has emerged as a promising method for synthesizing metal-organic frameworks (MOFs). It overcomes the limitations of the traditional solvothermal method to regulate the structure and function of the MOFs. This study synthesized various MOFs with different structures and functions by controlling the reaction time and the ratio of metal ions to organic ligands through microfluidics and investigated their CO2 adsorption properties. The results showed that the microfluidic synthesized defective and hierarchical pore MOF-808 improved the adsorption performance of CO2 by nearly 110% and 30%, respectively, compared with solvothermal synthesized MOF-808.

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 1.67 Omega cm(2) 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.

Abstract ：
The electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) represents a promising pathway for producing biomass-derived value-added chemicals. Nevertheless, the use of extremely expensive ion exchange membranes (IEMs) as separators significantly sacrifices the economic benefit in large-scale applications. Herein, we report a cost-effective non-fluorine cation exchange membrane (CEM) by grafting sulfonic acid (-SO3- ) groups onto the aromatic side chain of the polyethersulfone (PES) polymer. By tuning the content of -SO3 - groups, the physicochemical properties of the resulting CEMs can be easily adjusted. Impressively, the optimal HBS-PES-1.0 CEM with fully grafted -SO3- groups can achieve a high HMF conversion of 100 %, FDCA selectivity of 98.0 %, and Faradaic efficiency of 98.3 % when used as the separator for electrocatalytic oxidation of HMF, surpassing that of the commercial Nafion 117 membrane (100 % HMF conversion, 98.1 % FDCA selectivity, and 97.4 % Faradaic efficiency). This study provides a cost-effective and high-performance CEM as a substitute for the expensive commercial membrane, paving the way to large-scale commercial applications of biomass upgrading through the electrolysis process.

Abstract ：
D-Allulose, a C-3 epimer of d-fructose, has great market potential in food, healthcare, and medicine due to its excellent biochemical and physiological properties. Microbial fermentation for d-allulose production is being developed, which contributes to cost savings and environmental protection. A novel metabolic pathway for the biosynthesis of d-allulose from a d-xylose-methanol mixture has shown potential for industrial application. In this study, an artificial antisense RNA (asRNA) was introduced into engineered Escherichia coli to diminish the flow of pentose phosphate (PP) pathway, while the UDP-glucose-4-epimerase (GalE) was knocked out to prevent the synthesis of byproducts. As a result, the d-allulose yield on d-xylose was increased by 35.1%. Then, we designed a d-xylose-sensitive translation control system to regulate the expression of the formaldehyde detoxification operon (FrmRAB), achieving self-inductive detoxification by cells. Finally, fed-batch fermentation was carried out to improve the productivity of the cell factory. The d-allulose titer reached 98.6 mM, with a yield of 0.615 mM/mM on d-xylose and a productivity of 0.969 mM/h.
