Biofuel is a promising solution for energy crisis and excessive CO 2 emission. Membrane-based pervaporation process enhances biomass fermentation by constantly separating inhibitory bio-alcohols. However, dominating pervaporation membranes often show low permeation flux and inadequate separation factor. Herein we report the engineering fabrication of flexible composite hollow fiber membranes (HFMs) with oriented metal-organic framework (MOF@ZnO) arrays for ethanol-water separation. The epitaxial MOF arrays containing one-dimensional (1D) transport channels was constructed on HFMs, followed by a superhydrophobic and defect-free surface coating. The arrayed structure induces the flow pattern enhancement near the feed-membrane interface and increases mass transfer area, resulting in self-enhancing separation performance. The synergistic effects of the arrayed surface structure and MOF transport channels on separation performance enhancement were revealed by the experimental and simulation results. Impressively, for the composite HFM, the activation energy of ethanol was found to be lower than that of water. When applied to the pervaporation of a 5 wt% ethanol-water mixture, this membrane achieved an ultrahigh flux along with a good separation factor of 10.5. The versatile strategy is suitable for both inner- and outer-selective HFM modules as well as for various membrane materials which exhibit great potential for industrial applications.

The strong interfacial interaction between heterostructured semiconductors plays a vital role in enhancing the separation and transport efficiency of photogenerated charge carriers for photocatalytic applications. In this study, we report a stepwise synthesis strategy to fabricate a high-efficiency ternary heterojunction composed of NiS-decorated MoS₂/CdS with strong interfacial bonding (NS@SI-MCS). Initially, an amorphous MoSₓ layer was deposited onto CdS nanorods via chemical bath deposition, followed by thermal treatment in a reductive H₂/Ar atmosphere to form crystalline MoS₂ with strong interfacial coupling. This treatment not only improved the crystallinity of MoS₂ but also introduced sulfur vacancies, promoting enhanced interfacial contact and thereby strengthening electronic interactions and charge transport across the heterojunction. Subsequently, NiS nanoparticles were deposited as cocatalysts to facilitate efficient electron extraction and proton reduction. Comprehensive structural, optical, and electrochemical characterizations confirmed the formation of a well-integrated heterostructure, characterized by improved light absorption, suppressed charge recombination, and enhanced conductivity. The resulting NS@SI-MCS composite exhibited a remarkable hydrogen evolution rate of 5243 μmol h⁻¹g⁻¹ under visible light, approximately 16.6 times higher than pristine CdS. This enhancement is attributed to the synergistic effects of strong interfacial coupling of MoS₂/CdS and the catalytic contribution of NiS. This work provides valuable insight into designing strongly coupled heterojunctions and offers a scalable, noble-metal-free strategy for efficient solar-to-hydrogen conversion.

Stimuli-responsive active corrosion protection coatings serve as both an effective physical barrier and an active corrosion protection system for metallic substrates. However, their long-term performance is typically limited by the irreversible release of inhibitors and a restricted loading capacity, which hinders their repeated active corrosion protection capability and sustained durability. To address these limitations, we have developed a smart dual-stimuli-responsive active corrosion protection coating (denoted as MSNs-BTA@PANI/PVB) by encapsulating benzotriazole (BTA) within mesoporous silica nanocontainers (MSNs) coated with a polyaniline (PANI) shell. PANI, serving as a reversible molecular switch responsive to pH and redox conditions, enables controlled BTA release, ensuring sustained corrosion inhibition and prolonged service life. UV-vis spectroscopy revealed that in 3.5 wt% NaCl solution, minimal surface-adsorbed BTA was released from MSNs-BTA@PANI nanocontainer under pH change, whereas 0.54 mmol L − 1 release was triggered upon N 2 H 4 . After 50 days of immersion, EIS results showed that the coating containing 0.5 wt% MSNs-BTA@PANI achieved a |Z| 0.01Hz value of 1.14 × 10 5 Ω cm 2 , nearly seven times higher than that of the 0.5 wt% MSNs/PVB coating. This enhancement stems from the synergy between the physical barrier effect of MSNs and the dual-stimuli-triggered release of BTA, enabling effective localized corrosion inhibition. This work provides a reversible and controllable active protection strategy based on dual-responsive nanocontainers for designing durable intelligent corrosion protection coatings.

Global lithium demand has heightened interest in direct extraction from salt-lake brine. Mn-based ion sieves (HMOs) offer high capacity, fast kinetics, and low cost but suffer from Mn dissolution. This study reports a low-dissolution HMO@Hy sieve prepared via hydrothermal carbon coating. The oxygen-rich carbon layer curbs metal leaching without performance loss seen in amorphous carbon coatings, reducing Mn dissolution from 2.01% to 1.06%. The material exists as loose powder with a uniform 2–3 nm coating and adsorbs 21.1 mg/g from real brine within one hour. First-principles calculations show the carbon-doped coating raises surface Mn valence, reducing charge density and limiting dissolution during desorption. Granulation and cycling tests confirm practical potential: one ton of adsorbent processes 114 tons brine weekly, yielding 0.49 tons Li₂CO₃ and ¥42,800 economic benefit. This non-metallic coating strategy enhances HMO stability for sustainable lithium recovery.

Confining Cu clusters into covalent organic frameworks (COFs) has been revealed to be an effective strategy to enhance the stability of Cu clusters for the electrocatalytic conversion of carbon dioxide (CO₂) to ethylene (C 2 H 4 ). However, this strategy still exhibits unsatisfactory selectivity and efficiency. Herein, the reaction of a trinuclear Cu-cluster-based building unit, tris(4-μ 2 -O-carboxaldehyde-pyrazolato-N, N′)-tricopper (Cu 3 ), with a 4-connected square-planar linker of 4,4′,4”″,4″′-(pyrene-1,3,6,8-tetrayl)tetraaniline (Py) afforded a trinuclear Cu-cluster-containing three-dimensional (3D) COF, named 3D-Cu 3 -Py-COF. Powder X-ray diffraction combined with theoretical simulations reveals the crystalline nature of 3D-Cu 3 -Py-COF with a tbo topology. Comparative studies demonstrate that the 3D framework of 3D-Cu 3 -Py-COF enhances the exposure of active sites and improves CO 2 adsorption capacity. This, in cooperation with the capacity of trinuclear Cu-cluster moieties to facilitate C C coupling, endows 3D-Cu 3 -Py-COF with excellent electrocatalytic performance and selectivity for CO₂ reduction reaction (CO₂RR) to C 2 H 4 , exhibiting a maximal Faraday efficiency of 44.6% for C 2 H 4 at −0.8 V vs. reversible hydrogen electrode. This work should be helpful for the strategic design and fabrication of efficient Cu-cluster-based electrocatalysts for promoting the conversion of CO₂ into valuable carbon-based fuels.

Although both aluminum/polyvinylidene fluoride (Al/PVDF) and aluminum/polytetrafluoroethylene (Al/PTFE) systems exhibit excellent combustion performance, the study on comparing their combustion behaviors and the underlying mechanisms responsible for their differences are still relatively limited. Therefore, the advantages and disadvantages of the Al/PVDF and Al/PTFE systems were compared through ignition experiments and molecular dynamics simulations. The Al/PTFE system exhibits higher combustion intensity, and the characteristic is attributed to the higher fluorine (F) content in PTFE, which triggers more Al-F reactions. In contrast, the Al/PVDF system exhibits a lower ignition delay time and higher combustion heat, which is attributed to the relatively lower initial decomposition temperature, the higher hydrogen (H) content, and the higher combustion heat in PVDF. Compared to oxygen (O) atoms, H atoms can penetrate the oxide film on the surface of Al particles more rapidly and react with the inner Al atoms, thereby reducing the temperature required for Al atoms to break through the oxide film and participate in reactions.

In colloidal mixtures, different particle types coexist in the same suspension environment yet exhibit intrinsically distinct surface chemistries. Here we present surface-dictated sorting rules that enable selective assembly among mixed colloids. Using seven types of particles of equal size (∼2 μm) representing common families of negatively charged stable colloids, including inorganic spheres bearing native surface hydroxyls groups (M–OH, e.g. SiO 2 , TiO 2 ) or grafted carboxyl groups, organic polymer particles synthesized by emulsion polymerization (sulfonated PS and PMMA, carboxylated PS), and an organosilane-derived colloid with silanol surface (TPM), we identify three general strategies: (1) pH and solvent dielectric tuning, suppresses the dissociation of weakly acidic surface groups, driving particles with near-neutral M–OH or –COOH sites to clusterize; (2) Small molecules with multiple hydrogen-bonding sites (i.e., urea), reorganize interfacial hydrogen-bond networks, selectively destabilizing the surfaces of hydroxyl-rich inorganic particles; (3) Depletion-driven assembly with Pluronic surfactants. Upon selective adsorption onto hydrophobic particles (e.g., polystyrene), Pluronic copolymers form a stable surface brush layer, increasing the effective radius of the particles. This expanded depletion zone creates greater overlap as particles approach, resulting in enhanced depletion attraction. When combined with disparities in intrinsic surface potential, this brush-mediated interaction yields distinct overall potentials between hydrophobic and hydrophilic particles, thereby driving the preferential assembly of the hydrophobic ones. Applying this strategy to SiO 2 /Pt Janus particles further induces neutral charged Pt-facet clustering under depletion, yielding oriented clusters and chain-like assemblies.

Acute ischemic stroke (AIS) presents significant challenges in biomarker discovery and detection. This study addresses these hurdles through an integrated strategy encompassing multi-omics screening, experimental validation, machine learning-based prognostic assessment, and the development of a high-performance electrochemical immunosensor. We identified solute carrier family 2 member 3 (SLC2A3) as a novel candidate biomarker through combined transcriptomic and proteomic analysis. Its upregulation was confirmed in a mouse middle cerebral artery occlusion followed by reperfusion (MCAO I/R) model and in a prospective clinical cohort of 449 AIS patients. A Gradient Boosting Machine (GBM) model, incorporating SLC2A3 levels, effectively predicted 90-day functional outcomes (validation AUC = 0.933). For ultra-sensitive detection, a sandwich-type electrochemical immunosensor was fabricated. The sensing platform utilized a carboxylated single-walled carbon nanotubes (SWCNT) integrated with gold nanoparticles (AuNPs)-modified electrode. Signal amplification was achieved using a novel NH 2 -MIL-88B@PAA@PtCu nanocomposite probe, which combined the high catalytic activity of PtCu nanoflowers with the excellent loading capacity of the Fe-metal-organic framework (MOF). The immunosensor demonstrated outstanding performance for SLC2A3 detection: a wide linear range (0.078-10 ng mL −1 ), an ultra-low detection limit (9.3 pg mL −1 ), high specificity, and good reproducibility. Recovery rates in spiked human serum were 100.5-104.0%. This work establishes a complete pipeline from biomarker identification to practical sensing device development, offering a promising translational approach for prognostic assessment in AIS.

Aniline, a toxic volatile organic compound, presents considerable risks to human health and environmental safety. In this study, we have developed a novel composite fluorescent probe, named as CPB@Eu-MOFs, fabricated through the integration of perovskite quantum dots (CPB) into a europium-based metal-organic frameworks (Eu-MOFs). This composite serves as a self-calibrating, ratiometric fluorescent probe for the detection of aniline. It exhibits high selectivity towards aniline over common interfering volatile organic compounds, as well as a high sensitivity with a detection limit of 4.72 × 10 −6 M and a wide linear response range from 5 × 10 −4 to 10 −1 M. A distinct photoluminescence color evolution from red to orange, yellow, green and finally blue is observed with increasing aniline concentration, enabling rapid visual quantification alongside instrumental analysis. This work proposes a convenient and reliable dual-mode sensing strategy, combining visual and ratiometric fluorescence readouts, for monitoring aniline in environmental and industrial safety applications.

Hybrid lithium–sulfur batteries utilizing a sulfide solid electrolyte separator exhibit high specific capacity and excellent redox kinetics. Moreover, the sulfide separator can block material exchange between the cathode and anode, eliminating shuttle effect occurrence and enhancing battery cycling stability. However, the long-term cycling stability of these hybrid batteries is still compromised due to the gradual release of soluble thiophosphate from the sulfide separator. Here, we minimized the release of the leachate from the separator through the implementation of a soaking treatment of the separator in an ether solution of lithium salt prior to battery assembly. Consequently, reducing the release of the leachate inhibits the growth of lithium dendrites on the anode, thereby lowering the risk of battery short-circuits. It also suppresses the formation of a passivation layer on the cathode associated with redox products of the leachate, thus ensuring rapid redox kinetics of the cathode. Benefited from this presoaked sulfide separator, the hybrid lithium–sulfur batteries maintained a high discharge capacity of 810 mA·h·g–1 and a high secondary discharge plateau voltage of 2.04 V after 500 cycles.

Black phosphorus (BP) nanosheets were synthesized through high-energy ball milling and liquid-phase exfoliation. The impact of BP on the tribological characteristics of castor oil (CO) was evaluated by using a four-ball test. The lubrication and extreme pressure performance of oil-based lubricants containing various mass fractions of BP nanosheets were examined in steel/steel frictional pairs, with the results compared to pure CO. Experimental results demonstrate that BPNS significantly fortifies the load-carrying capacity and antiwear resistance of the base oil, achieving a 43% reduction in friction and an 83% decrease in wear volume, alongside a 54% increase in extreme pressure performance. Molecular dynamics simulations revealed that when BP was introduced into the system, the friction force decreased by 44.4%. These enhancements are primarily attributed to the formation of the tribo-chemical layer consisting of iron oxides (Fe2O3, Fe3O4) and POx/P–O–C and the physical adsorption film on the worn surface. The interlayer shear properties of BP nanosheets also contribute significantly to reducing friction and mitigating wear.

Ammonia (NH 3 ) is a toxic and pungent gas with significant implications for environmental monitoring, industrial safety, and human health. Therefore, the development of high-performance sensors for NH 3 detection at room temperature is of great necessity. This work develops a Bi 2 MoO 6 /Ti 3 C 2 T x 2D/2D heterostructure-based NH 3 gas sensor. The material demonstrated outstanding NH 3 sensing characteristics, involving high sensitivity (R a /R g =25.6 at 100 ppm), quick response time (21 s), and quick recovery time (72 s) at room temperature. Meanwhile, the sensor demonstrated prominent stability, repeatability, humidity-resistant, and an optimal operating temperature for NH 3 detection. Density functional theory (DFT) simulations were applied to examine the adsorption behavior of NH 3 on the Bi 2 MoO 6 /Ti 3 C 2 T X surface, which shed light on the sensing process. Additionally, a prototype detection system was developed to monitor NH 3 emissions from spoiled fish samples, illustrating how this sensor could be applied to monitor food safety.
