Lithium-sulfur (Li-S) batteries with attractive capacity give remarkable potential for prospective high-capacity application scenarios but suffer a fatal flaw of short cyclability before large-scale commercialization especially owing to polysulfide (Li 2 S n ) transmembrane shuttling. To efficiently restrain chronic Li 2 S n shuttle and expedite Li + transfer, herein, a novel electriferous charge-mosaic S(TMC@Lys-Li) separator preparation approach is recommended. Interfacial polymerizations of lithiated lysine and trimesoyl chloride establish an electriferous charge-mosaic polyamide functional layer. Substituted Li within the charge-mosaic layer offers transition or replacement sites for smoothing Li + migrations, which constructs efficient Li + fast-transfer private channels and accelerates the Li + transfer rate to 9.4 times. Negatively charged polyamide skeleton synchronously heightens Li 2 S n rejections by combining Donnan and steric effects. S(TMC@Lys-Li) replenishes Li for homogenizing Li nucleation and growth, endowing stable plating/stripping behaviors over 250 cycles for Li-Cu batteries. Assembled Li-S cells thus exhibit excellent specific capacity and cyclability at multiple application scenarios such as long periods, high areal capacity, and fast charge, holding 78.1% retention after 500 cycles at 1 C. The superior thermal stability and self-discharge of S(TMC@Lys-Li) dramatically strengthen battery thermal runaway resistance even at 155 ℃, which ensures security for Li-S battery high-power and high-temperature operations. Above alluring features enable charge-mosaic separators to be potentially adopted in practical Li-S batteries demanding strict security, high-capacity density, and fast charge technology.

Many industries produce large amounts of glycerol-based wastewater, which always contains hazardous organic chlorides. Compared with complicated biological treatments or physical adsorption, membrane separation decreases the cost and saves energy. Strong swelling of traditional thin-film composite (TFC) membranes influence the performance in the separation of organic molecules. Here we prepared TFC membranes with an acrylamide-grafted PAN support layer to copolymerize with m-phenylenediamine (MPD) and trimesoyl chloride (TMC). The link of separative layer and support layer was created like a zipper stitching to enhance the stability and resistance for the removal of organic molecules. An aquatic grass-like layer of acrylamide enlarges the surface area and hydrophilicity with superior separation performances (15.8 LMH bar −1 flux, 72.0% rejection of dichloropropanol (DCP) and 64.6% rejection of glycerol (Gl)). The trade-off upper bound was improved to a high level. We also established the simulations of evaporation using Aspen Plus and mathematical models of reverse osmosis to calculate the energy consumption corresponding to the recycle of glycerol-based wastewater. The experimental and theoretical results illustrate the advantages of acrylamide-grafted TFC membranes in the ap-plications to concentrate organic solutes and treat wastewater.

Nanofiltration (NF) has the potential to achieve precise ion–ion separation at the subnanometer scale, which is necessary for resource recovery and a circular water economy. Fabricating NF membranes for selective ion separation is highly desirable but represents a substantial technical challenge. Dipole–dipole interaction is a mechanism of intermolecular attractions between polar molecules with a dipole moment due to uneven charge distribution, but such an interaction has not been leveraged to tune membrane structure and selectivity. Herein, we propose a novel strategy to achieve tunable surface charge of polyamide membrane by introducing polar solvent with a large dipole moment during interfacial polymerization, in which the dipole–dipole interaction with acyl chloride groups of trimesoyl chloride (TMC) can successfully intervene in the amidation reaction to alter the density of surface carboxyl groups in the polyamide selective layer. As a result, the prepared positively charged (PEI-TMC)-NH2 and negatively charged (PEI-TMC)-COOH composite membranes, which show similarly high water permeance, demonstrate highly selective separations of cations and anions in engineering applications, respectively. Our findings, for the first time, confirm that solvent-induced dipole–dipole interactions are able to alter the charge type and density of polyamide membranes and achieve tunable surface charge for selective and efficient ion separation.

Interfacial polymerization (IP) has been widely utilized to synthesize composite membranes. However, precise control of this reaction remains a challenge due to the complexity of the IP process. Herein, an optical three-dimensional microscope was used to directly observe the IP process. To construct copolyesteramide containing phthalazine moiety films, rigid monomer 4-(4′-hydroxyphenyl)-2,3-phthalazin-1-one (DHPZ) and flexible monomer piperazine (PIP) were used as aqueous phase monomers, and trimesoyl chloride (TMC) served as the organic phase monomer. Multilayer cellular structures were observed for the copolyesteramide films during the IP process. The effects of multiple factors including the ratio between flexible and rigid monomers, co-solvents, and the addition of phase transfer catalysts on the film growth and the morphologies were investigated. This research aims to deepen our understanding of the IP process, especially for the principles which govern polymer film growth and morphology, to promote new methodologies for regulating interfacial polymerization in composite membrane preparation.

To address the critical challenge of lithium extraction from high Mg 2+ /Li + ratio brines, this study develops a high-performance separation membrane through synergistic regulation of binary and ternary acyl chloride monomers combined with a bis-quaternary ammonium salt surface modification strategy. Optimizing the ratio of terephthaloyl chloride (TPC) to trimesoyl chloride (TMC) facilitates the formation of a periodic stripe Turing structure on the piperazine-based polyamide membrane's surface, markedly increasing the effective permeation area and water flux. The study reveals that adjusting the TPC ratio finely tunes the polyamide network's crosslinking density, thereby affecting the size exclusion effect. Additionally, TPC incorporation, by diminishing surface carboxyl density, enhances the membrane's surface positive charge, significantly improving its Li + permeability and Mg 2+ rejection capabilities. The optimized TPC-20 membrane demonstrates exceptional ion selectivity, achieving a MgCl 2 rejection of 91.3 %, a LiCl rejection of 11.3 %, and a water flux of 61 LMH. Further enhancement via amino-terminated bis-quaternary ammonium salt (ATBAS) grafting achieves 98.7 % Mg 2+ rejection, a record Li + negative rejection of -37.3 %, and a Mg 2+ /Li + selectivity of 105.1. Extended testing for 120 h verifies the membrane's reliable performance, highlighting its potential for industrial application. This research provides an efficient and energy-saving membrane separation solution for lithium extraction from brines.

The high-performance nanofiltration (NF) membranes were fabricated by using hydrolyzed polyacrylonitrile (HPAN) ultrafiltration (UF) membranes with negatively surface charges as the substrate membranes, quaternized crosslinked microgels (PNI6) with positive charges as the intermediate layer, piperazine (PIP) and trimesoyl chloride (TMC) as the monomers for the formation of polyamide selective layer via interfacial polymerization (IP). The introduction of positively charged PNI6 microgels as the intermediate layer improved the hydrophilicity of resultant NF membranes and rendered the NF membranes with surface positive charges. The obtained NF membranes (MG-NF) with PNI6 microgel interlayer simultaneously achieved excellent water flux and the rejection of salts including Na 2 SO 4 , MgSO 4 , MgCl 2 , and CaCl 2 . Increasing the deposition time of PNI6 microgels on the HPAN UF substrate membranes increased the water flux and rejection of MgCl 2 of the resultant MG-NF series NF membranes. The nanofiltration performance of obtained MG-NF series NF membranes exhibited thermo-sensitivity and long-term stability. For MG-NF-6 NF membrane, the water flux and rejection of MgCl 2 reached 10.1 L·m −2 ·h −1 ·bar −1 and 93.4 % at 25 °C, respectively. With increase of temperature, the water flux of MG-NF-6 membrane was significantly enhanced to be 13.4 L·m −2 ·h −1 ·bar −1 at 45 °C, while the rejection of MgCl 2 slightly decreased to be 90 %.

Dietary intake and nutrient composition regulate animal growth and development; however, the underlying mechanisms remain elusive. Our previous study has shown that either the mammalian deafness homolog gene tmc-1 or its downstream acetylcholine receptor gene eat-2 attenuates Caenorhabditis elegans development in a chemically defined food CeMM ( C. elegans maintenance medium) environment, but the underpinning mechanisms are not well-understood. Here, we found that, in CeMM food environment, for both eat-2 and tmc-1 fast-growing mutants, several fatty acid synthesis and elongation genes were highly expressed, while many fatty acid β-oxidation genes were repressed. Accordingly, dietary supplementation of individual fatty acids, such as monomethyl branch chain fatty acid C17ISO, palmitic acid and stearic acid significantly promoted wild-type animal development on CeMM, and mutations in either C17ISO synthesis gene elo-5 or elo-6 slowed the rapid growth of eat-2 mutant. Tissue-specific rescue experiments showed that elo-6 promoted animal development mainly in the intestine. Furthermore, transcriptome and metabolome analyses revealed that elo-6 /C17ISO regulation of C. elegans development may be correlated with up-regulating expression of cuticle synthetic and hedgehog signaling genes, as well as promoting biosynthesis of amino acids, amino acid derivatives and vitamins. Correspondingly, we found that amino acid derivative S-adenosylmethionine and its upstream metabolite methionine sulfoxide significantly promoted C. elegans development on CeMM. This study demonstrated that C17ISO, palmitic acid, stearic acid, S-adenosylmethionine and methionine sulfoxide inhibited or bypassed the TMC-1 and EAT-2-mediated attenuation of development via metabolic remodeling, and allowed the animals to adapt to the new nutritional niche.

Aliphatic polycarbonates gels have received unprecedented attention due to their environmentally friendly and sustainable properties. However, traditional aliphatic polycarbonates gels lacking functionalization properties are not able to meet the requirements of future innovations. Based on this situation, in this study, novel functionalized aliphatic polycarbonate gels PEG 2000 - b -P(TMC-co-MCC) n are developed. The formation of hydrogen bonds network endows the gel with good comprehensive performances. Accordingly, the gel possesses a tensile strength and stretchability up to 2.62 MPa and 397.7%, presents a shape recovery rate of 97.7% in 9 s at 30 °C and also can repair crack at room temperature for 4.5 h without any external stimulation. Furthermore, these performances can be regulated by the ratio of the flexible segment, and the specific relationships between them are also presented. Notably, the cross-linking mechanism of the gels PEG 2000 - b -P(TMC-co-MCC) n is also proposed. Significantly, the transition states, energy barriers and reaction enthalpies of each step in the formation of oligomers by ring-opening polymerization of small molecules are calculated by density functional theory to deepen the understanding of the reaction mechanism. This aliphatic polycarbonate gel with excellent shape memory and self-healing properties provides prospects for developing the biomaterials such as surgical sutures and stents, as well as flexible electronics.

ABSTRACT Bio-fouling is a key issue for the nanofiltration operation. In this study, 1, 2-bis ( N -aminoethyl imidazoline) ethane (BAIE) firstly was used as a novel bisimidazoline aqueous monomer to prepare the anti-bacterial nanofiltration (NF) membranes. A novel nanofiltration (BAIE-TMC NF) membrane with in-situ anti-bacterial structure and anti-fouling property was fabricated via interfacial polymerization (IP) with trimesoyl chloride (TMC), basing on a polyethersulfone (PES) substrate. Protonated imidazole endowed the surface of BAIE-TMC NF membrane with weak electronegativity, and its salt rejection sequence was MgSO 4 > Na 2 SO 4 > MgCl 2 > NaCl > LiCl. Meantime, the BAIE-TMC NF membrane with 0.5 wt% BAIE (M-0.5) exhibited a high rejection for bivalent ions, with a high MgSO 4 rejection (94.7%). Notably, BAIE-TMC NF membrane containing an in-situ anti-bacterial imidazole structure showed significant anti-fouling and anti-bacterial properties. After BSA or HA filtration process, the flux recovery rates of all BAIE-TMC NF membranes were higher than 95%, and M-0.5 exhibited high inhibition performance against Escherichia coli (98.5%) and Staphylococcus aureus (98.4%). Furthermore, M-0.5 exhibited excellent long-term separation stability during the three weeks separation experiment. BAIE can serve as an effective aqueous monomer for fabricating in-situ anti-bacterial and anti-fouling NF membrane to achieve the rejection of organic pollutant and bivalent ions.

The demand to address issues such as drinking water safety and industrial fouling caused by high-hardness ions has still emphasized the development of advanced membrane materials. In this study, through a maneuverable amide-cross-linking strategy, a new positively-charged polyamide (PA) nanofiltration membrane was developed for the first time by incorporating amino-functionalized Ti 3 C 2 T x nanoparticles (Ti 3 C 2 T x -NH 2 , TN). In addition to the induced electropositivity, the hydrophilicity of the as-obtained PA-TN membrane was also elevated with a maintained nodular structure by tailoring the interfacial polymerization reaction process of piperazine (PIP) with trimesoyl chloride (TMC). Therefore, the newly developed PA-TN membrane exhibited both superhigh rejection of Ca 2+ and Mg 2+ over 96%, and the flux increased 2–3 times even for the salinity solutions than many similar NF membranes reported in literature. Furthermore, the enhanced long-term stability and fouling resistance of the PA-TN membrane was also validated due to its new organic-inorganic structural coupling and improved hydrophilicity. This work provides a new strategy for the preparation of organic-inorganic hybrid positively charged nanofiltration membranes for water softening treatment.

Polyamide thin-film composite reverse osmosis (RO) membranes usually suffer from fouling problem, which greatly limits the wide application of RO technology. In this study, a novel rigid-flexible interpenetrating polyamide RO membrane was fabricated via two step modifications to alleviate the membrane fouling during the RO process. The first step modification was carried out by incorporation a new aliphatic diamine of 1,3-diamino-2-propanol (DAPL) into the aromatic m-phenylenediamine (MPD) aqueous solution to react with trimesoyl chloride (TMC) to form a rigid-flexible interpenetration polyamide (PA) separation layer for enhancing its permeability. Then, the second modification was performed by grafting PVA on the top surface of the DAPL-based PA layer to tailor more hydrophilic, smoother and less negatively charged surface and endowed the modified membrane favorable antifouling property. Under the optimized condition, the permeability flux of the modified RO membrane reached 58.6 L/m 2 h with an about 58.8% increase than the pristine RO membrane (about 36.9 L/m 2 h), and the salt rejection was also maintained about 99.6% without any loss. At the same time, the modified RO membrane presented a favorable resistance to the dye foulants of methylene blue (MB) and crystal violet (CV) with flux recovery rate of 76.8% and 84.2% respectively. This study provides a facile and effective way to fabricate a novel antifouling reverse osmosis composite membrane with favorable comprehensive separation performance.

A new synthetic method was designed to prepare poly (trimesoyl chloride-co-polyethyleneimine) (PEI-TMC). Characterization of PEI-TMC was investigated by FTIR, SEM, EDS , XPS, TGA , and BET. TGA test revealed that the PEI-TMC had excellent thermal stability. The BET specific surface area (4.74 m 2 g −1 ) and pore diameter of about 9.44 nm indicated that PEI-TMC possessed a mesoporous structure. The adsorption behavior of U(VI) on the PEI-TMC was investigated. The thermodynamic analysis showed that the process of PEI-TMC adsorption of U(VI) was endothermic and spontaneous, and the adsorption efficiency was better at higher temperatures. The U(VI) sorption on PEI-TMC was conformed to the Langmuir adsorption isotherm and pseudo-second-order kinetic models . The adsorption mechanism of U(VI) with PEI-TMC was systematically elucidated by XPS and FTIR. Under the best condition, the maximum adsorption capacity of PEI-TMC could reach 212.8 mg g −1 by calculating the Langmuir isothermal model. It indicated that PEI-TMC was a potential adsorbent for the treatment of U(VI)-containing wastewater.
