MXene displays exceptional promise for water purification, owing to its versatile surface chemistry and favorable physicochemical properties. However, its separation performance is substantially hindered by intercalation-induced swelling. Here, inspired by the “brick-and-mortar” structure of nacre, nacre-like nanocomposite membranes are developed through the co-assembly of MXene nanosheets (bricks) and polyetherimide (mortar). Leveraging MXene's unique properties, polyetherimide serves three pivotal functions: it acts as "spacer", precisely defines the interlayer spacing at ∼13.84 Å; it functions as "regulator", abundant hydrophobic groups regulate the microenvironment within the nanochannels; and it serves as "stabilizer", establishes robust non-covalent interactions with the MXene basal planes, thereby reinforcing channel integrity. Consequently, the resulting membranes exhibit outstanding stability in aqueous media, achieving a swelling ratio as low as 1.56%. Remarkably, after 1080 h of static water immersion, the membrane retained a relatively stable interlayer structure and separation performance, demonstrating prolonged aqueous stability. This bioinspired strategy provides critical insights for the rational design of structurally stable two-dimensional membranes.

Graphical The Ni 3 Fe 1 -BC composite, featuring a coral-like mesoporous architecture and exposed Ni 2+ /Fe 3+ active sites, facilitates the rapid, monolayer adsorption of methyl blue through strong Ni─O coordination. The process follows Langmuir isotherm and pseudo-second-order kinetics, indicating high affinity and thermodynamic spontaneity. In this paper, the coral-like structure of Ni/Fe bimetallic atom cluster composite adsorbent (Ni 3 Fe 1 -BC) was utilized for the efficient removal of methyl blue (MB), and a removal rate of 98% could be achieved within 25 min. The large specific surface area and mesoporous structure of the material provide effective channels for the diffusion and adsorption of MB molecules. Ni 2+ and Fe 3+ species act as key adsorption sites during the adsorption process, especially when the oxygen atoms in MB first interact with Ni atoms to form a stable chemical bond, which enhances the stability of adsorption. Meanwhile, the adsorption process conformed to the pseudo-secondary kinetic model, and the isotherm analysis showed that the Langmuir model fitted better, reflecting the monolayer adsorption characteristics. The adsorption energy E ads = −2.04 eV further proved that the adsorption process was spontaneous and exothermic with good thermodynamic stability. In addition, Ni 3 Fe 1 -BC exhibits excellent adaptability and cyclic stability in different water environments, making it an efficient and stable adsorbent for water treatment.

The escalating industrial activities in metal processing, textile manufacturing, petroleum refining, leather production, and pulp industries have generated substantial amounts of industrial wastewater, presenting critical environmental challenges that require immediate attention. In this study, we developed a novel polyacrylonitrile grafted ionic liquid (PAN-g-IL) membrane through γ-ray irradiation-induced grafting of 1-vinyl-3-ethylimidazolium bromide onto polyacrylonitrile, followed by non-solvent induced phase separation (NIPS) membrane fabrication [1] . The developed membrane exhibited exceptional separation performance for both dye-laden and oil-contaminated wastewater systems. The PAN-g-IL membrane demonstrated a pure water flux of 358.1 L m −2 h −1 with remarkable rejection rates exceeding 98% for cationic dyes, and for oil–water emulsions has a very good retention performance [2] , indicating superior antifouling properties and long-term operational stability.

Achieving long-range bubble transport in liquid is crucial to enable high-efficiency water splitting and bubble harvesting. This study presents a simple and effective method for fabricating a unique sandwich-structured material with aerophobic/aerophilic/aerophobic symmetric wettability. The design of this structure ensures that bubbles move unidirectionally from the aerophobic regions on either side into the central aerophilic channel, while the reverse passage through the copper foam is prevented. Furthermore, experimental results demonstrate that the unique structure enables versatile underwater bubble transport behaviors, including wave-like and spiral paths, thereby facilitating long-range, efficient directional movement. This long-range, spontaneous, and directional pumpless transport of underwater bubbles allows for efficient water splitting. Combining experimental results with theoretical calculations, the unique structure effectively mitigates H 2 (hydrogen) bubble accumulation on the electrode surface, thereby promoting efficient mass transfer during electrolysis. Moreover, its superior bubble transport capability enables efficient bubble collection, even in complex environments, making it highly suitable for gas-related applications.

Graphene oxide membranes hold promising application potential in molecular nanofiltration, but the traditional selectivity-permeability trade-off is still a challenge. Here, an interfacial redox reaction strategy based on poly(m-phenylenediamine)-graphene oxide (PmPD-GO) interaction was successfully designed to achieve the fabrication of an ultrathin graphene oxide membrane (∼28 nm) with a reasonable reduction state (C/O ratio of 11.2) and adequate interlayer spacing stabilized at 8 ± 0.5 Å, which supplies not only a favorable microenvironment for fast water transport but also a suitable interlayer distance for molecules gating. The resultant membrane exhibits a high permeance of 72 LMH/bar and an exceptional dye rejection rate exceeding 98%. Moreover, the gentle gradient-reduced graphene oxide membrane has significantly improved stability under long-term immersion, pH tolerance, and ultrasonic treatment tests. This research provided a simple and effective strategy for fabricating two-dimensional lamellar membranes with promising prospects for practical nanofiltration applications.

Background: The pathological hyperglycemic microenvironment in diabetic wounds increases susceptibility to bacterial infections and impairs wound healing. However, despite certain advancements in conventional clinical treatments, the pathological issues have not yet been fundamentally resolved. The mechanism that amplifies ferroptosis through disruption of the bacterial electron transport chain (ETC) results in effective bacterial eradication and facilitates wound healing, thereby offering novel therapeutic potential for the management of diabetic wound infections. Methods: This work designs a multi-enzyme-mimicking Fe-WS 2 @GOx nanozymes by loading glucose oxidase (GOx) onto defect-engineered Fe-WS 2 , which disrupts the bacterial ETC and induces ferroptosis, thereby accelerating diabetic wound healing. Results: During the bacterial infection stage, the Fe-WS 2 @GOx nanozymes with abundant sulfur vacancies can simultaneously mitigate hyperglycemic and alleviate the hypoxic microenvironment. This is achieved through continuously producing substantial amounts of reactive oxygen species (ROS), resulting in endogenous glucose consumption, promoting cyclic accumulation of H 2 O 2 , and ensuring a sustained oxygen supply. Meanwhile, the generated ROS interferes with the bacterial ETC, impedes bacterial energy metabolism and inhibits biosynthesis, ultimately leading to bacterial death. More importantly, at the new tissue proliferation stage, Fe-WS 2 @GOx can promote wound angiogenesis and tissue regeneration by macrophage immunomodulatory effect. Conclusions: Therefore, this study provides a new paradigm strategy for diabetic wound infections therapy by “electron transport chain interference” amplified bacterial ferroptosis.

Superhydrophobic surfaces are prone to structural damage and degradation of low-surface-energy substances, which significantly affects their long-term stability and performance in anti-/de-icing applications. Inspired by the self-recovery capability of lotus leaves, a migration of low-surface-energy substance-mediated self-healing superhydrophobic coating was fabricated by spraying a mixture of silicone nanofilaments (Si NFs), liquid paraffin-loaded hollow silica microspheres (LP/H-MPs), trimethoxy (1H, 1H, 2H, 2H-heptadecafluorodecyl) silane (TMHFDS), and epoxy resin (E51). The coating demonstrated significant robustness, achieving a hardness of 2H and outstanding superhydrophobicity, characterized by a water contact angle (CA) exceeding 161° and a sliding angle (SA) below 2°. The preserved liquid paraffin also endowed the hybrid coating with a self-healing ability. Consequently, when the surface is mechanically damaged or chemically degraded, the superhydrophobicity can rapidly recover upon heating at 200 °C, and the self-healing is repeatable. After nine cycles of O 2 plasma etching and self-healing, the coating maintained its liquid repellency, with a significant CA exceeding 164°. When exposed to a cold, high-humidity atmosphere, the self-healing superhydrophobic coating significantly delayed ice formation to 1105 s, enabling frost prevention. The synergistic effects of its robustness, superhydrophobicity, and self-healing properties indicate that the as-prepared self-healing superhydrophobic coating has great potential in wind power generation, transportation, and other fields.

Layered double hydroxide (LDH) membranes, featuring uniform interlayer nanochannels, hold substantial potential for molecular sieving in aqueous solutions. In this study, polyethyleneimine (PEI) rich in amino groups is used as bridging unit to develop a robust PEI-bridged-LDH composite membrane with enhanced molecular sieving performance. The introduction of PEI bridges adjacent nanosheets, strengthens the interlayer bonding strength, creating a continuous LDH nanosheet membrane with high selectivity. Owing to the well-designed lamellar structure ans excellent hydrophilicity, the PEI-bridged-LDH composite membrane achieves high water permeance (864.5 L m −2 h −1 bar −1 ) and superior dye/salt separation performance, with outstanding dye rejections (e.g., Congo Red: 99.1%, Methyl Blue: 99.3%, Victoria Blue B: 99.7%) and low salt rejections (e.g., Na 2 SO 4 : 5.7% and NaCl: 2.2%). Moreover, the PEI-bridged-LDH composite membranes show high mechanical strength due to the hydrogen bond interactions between PEI and LDH nanosheets, thereby exhibiting robustness against mechanical damage and under high trans-membrane pressure of 5 bar. Besides, the composite membrane also demonstrates outstanding anti-fouling properties and long-term operation durability for dye/salt mixtures, suggesting its great potential in treating practical textile wastewater. This work opens a new avenue for developing robust LDH membranes for continuous and stable dye/salt separation.

In this study, PVDF/SMA membranes were fabricated via non-solvent induced phase separation(NIPS), followed by grafting of polyethyleneimine (PEI) onto the membrane surface through reaction with the anhydride groups of SMA, yielding PVDF/SMA-PEI membranes. Owing to the considerable free volume of PEI chains, stacking tends to occur during cross-linking with SMA, resulting in a loose selective layer and poor retention of small- to medium-sized dye molecules. To address this, the small-molecule additive sodium dodecyl sulfate (SDS) was introduced into the PEI solution. The electrostatic interaction between the sulfate ions of SDS and PEI promotes a more uniform distribution of PEI on the membrane surface, reducing inter-chain aggregation and forming a denser selective layer. The resulting PEI-SDS membrane maintained a high pure-water flux of 220 L/m 2 ·h while achieving methyl blue, indigo carmine, and acid fuchsin rejection rates of 98.86%, 99.57%, and 86.77%, respectively. In conclusion, this work provides a simple method for preparing highly efficient positively charged membranes for dye removal.

Multidrug-resistant bacterial pneumonia (MDR-BP), particularly involving biofilm eradication, presents therapeutic challenges. While reactive oxygen species (ROS)-mediated chemodynamic therapy offers antibacterial potential, limitations in biocatalytic performance and nanotherapeutic efficacy hinder traditional approaches. We developed nitrogen-doped ruthenium single-atom catalysts (Ru-N-SACs) as a dual-functional nanotherapeutic platform. This nanozyme exhibits peroxidase-mimicking catalytic activity, generating ROS selectively. Near-infrared laser stimulation further enhances its activity and provides photothermal disruption of biofilms. The resulting synergistic action achieves complete biofilm eradication and improves survival in pneumonia models. Comprehensive multi-omics analyses elucidated the therapeutic effectiveness and regulatory mechanisms of Ru-N-SACs against MDR-BP pathogenesis. This work demonstrates a paradigm combining catalytic ROS generation and photothermal therapy for managing deep-tissue infections. It advances the design of precision-engineered nanozymes within antimicrobial nanomedicine, addressing the critical need for innovative strategies against MDR pathogens.

Photocatalytic oxygen reduction reaction offers a sustainable approach for hydrogen peroxide (H 2 O 2 ) synthesis, while the efficiency is limited by the challenge of synergistically optimizing the supply of oxygen, protons, and electrons. Here, by elaborately developing squaric acid-based zwitterionic covalent organic framework (STT COF), we propose a triple synergy strategy for boosting H 2 O 2 photosynthesis. The as-prepared STT COF delivers a high H 2 O 2 yield of 14356.5 μmol g –1 h –1 in pure water, with a notable apparent quantum yield of 40.0% at 420 nm, roughly 7.9 times that of its charge-neutral counterpart and outperforming other documented systems. Under natural sunlight irradiation, a 5 L H 2 O 2 solution (~400 μM) is produced in a continuous flow membrane reactor equipped with STT COF and gas diffusion layers. Mechanism studies demonstrate that STT COF induces a strong donor-acceptor (D-A) interaction to promote electron transfer, undergoes spontaneous hydrogenation for continuous protons and facilitating oxygen uptake in a favorable configuration, collectively creating a triple synergy to boost H 2 O 2 photosynthesis.

Polyurethane foam (PUF) has the characteristics of light, loose and polyporous. These characteristics make it play a great role in the adsorption of offshore oil spill. However, the recovery of oil spills in the multi-microbial Marine environment requires not only high adsorption properties of materials, but also efficient antibacterial properties. In this study, we prepared amino acid doped antibacterial polyurethane foam (AA-PUF). Then, polydopamine (PDA) and modified multi-walled carbon nanotubes (MWCNTs) were used to modify the surface of polyurethane, and MWCNTs/PDA@AA-PUF with antibacterial property and excellent oil–water separation effect was prepared successfully. The modified AA-PUF had high absorption rate (23 times of self-weight) and could realize cyclic adsorption while preventing bacterial adhesion. These studies indicated that AA-PUF was modified by PDA and MWCNTs which can be used as an efficient oil–water separation material, and it can prevent the adhesion of bacteria. This special material has great potential for practical application in solving oil–water separation in complex environment.
