A high-quality quantum dots (QDs) layer is crucial for the commercialization of quantum dot light-emitting diode (QLED) devices. However, current fabrication techniques cannot simultaneously achieve monolayer coverage, ordered arrangement, and large-area scalability. Herein, we develop a novel strategy of continuous stepwise self-assembly for QDs monolayer integrated the air-liquid interfacial assembly technology with continuous line-ink-supply and Langmuir-Schaefer (LS) technology, which the QDs can be finely to assemble into large area ordered and dense QDs monolayer film at the trailing edge of the flow. The ordered QD monolayers can be repeatedly transferred and stacked to accurately control the thickness of the luminescent layer in QLED devices. Green QLED based on this monolayer film reaches a high EQE of 23.85%. Furthermore, the optimized trilayer device exhibits negligible efficiency roll-off, retaining an EQE above 18% and a luminous efficacy of 60 lm W −1 at a luminance of 200 000 cd m −2 . This methodology also shows preliminary scalability potential. We achieved a trial fabrication of large-area QD films of 210 cm 2 and further constructed corresponding QLED devices with an emission area of 1.5 cm × 1.5 cm as an initial exploration.

This study reveals that electrolyte pH dominates proton concentration and transport kinetics in AHPBs. • At the optimal pH of 2.2, the specific capacity reaches 635.17 mAh g⁻¹, growing by 116.99% against the pH 5.2 baseline. • An Al³⁺-based pH regulation strategy is put forward to substitute strong acids. • It restrains zinc anode corrosion and hydrogen evolution, lifting the cycle life from 220 to 680 cycles (a 209% increase). • The synergistic effect of H⁺ and sulfate ions is clarified, which cuts electrode impedance and narrows charge-discharge voltage gaps, delivering design guidance for high-stable aqueous batteries. Aqueous hydrogen proton batteries (AHPBs) rely exclusively on the electrolyte for proton supply, making electrolyte pH a pivotal parameter governing overall electrochemical performance. In this work, we innovatively establish a continuous electrolyte-pH-gradient experimental system that overcomes the limitations of conventional single-point pH measurements. By integrating systematic electrochemical characterization with mechanistic analysis, we reveal for the first time that the regulation of battery performance by pH stems from the dual direct effect of H + concentration-gradient variations on (i) the thermodynamic equilibrium of the cell electromotive force and (ii) the kinetic process of H + migration. This insight demonstrates that activation of the Grotthuss proton-transport mechanism requires both a proton-rich milieu and a sufficiently dense network of weak hydrogen bonds, thereby deepening the microscopic understanding of H + diffusion pathways. Furthermore, we elucidate the correlation between cation valence state and the dissociation of protons in solvated water, leading to a novel strategy: replacing strong acids with high-valence cations to mitigate the shortened cycle life and low retention observed at low pH. These advances enrich and refine the design philosophy of AHPB electrolytes, opening avenues for acid-free formulations and promising to accelerate the rapid development of AHPB technology.

To address the persistent challenges in separating heavy rare earth elements (HREEs) with similar physicochemical properties, this study developed a novel U-shaped interwoven hollow fiber three-phase membrane module (UI-HFTPM) for the selective separation of yttrium ions (Y 3+ ) from Y-rich heavy rare earth solutions. The separation efficiency was systematically explored with respect to membrane structural parameters and operational conditions. Comparative experiments revealed that the UI-HFTPM outperformed parallel hollow fiber three-phase membrane modules (P-HFTPM), achieving a 99.03% purity for Y 3+ in the feed phase after 4 h of operation, while the separation factor ( SF ) between Y 3+ and other HREEs (i.e., SF Ho/Y , SF Er/Y , SF Tm/Y , SF Yb/Y , and SF Lu/Y ) reaching 4.40, 6.09, 6.80, 11.44, and 13.04 within 5 min of operation, respectively. When treating a high-concentration real feed (12.445 g L −1 ), the Y 3+ purity reached 97.20% at 12 h, slightly lower than that obtained under dilute conditions. Additionally, a three-dimensional (3D) computational fluid dynamics (CFD) model was developed to elucidate how secondary flow pattern, induced by the U-shaped structure, enhances radial mixing and thereby influences the mass transfer and reactive extraction/stripping of the representative rare earth ions (Y 3+ and Er 3+ ). This study demonstrates the capability of the CFD model for qualitatively predicting the effects of operational and structural parameters on Y 3+ separation, providing theoretical guidance and technical support for the design, scale-up, and optimization of advanced hollow fiber membrane modules for sustainable rare earth separation.

A 3D honeycomb-like Ni–Co–Mn oxide composite is grown on carbon cloth. • Multi-component synergy enhances charge storage. • The electrode delivers 349.7 mAh g −1 and retains 90% capacitance after 30,000 cycles. • An asymmetric device achieves 68.99 Wh kg −1 and 98.33% retention after 20,000 cycles. Exploring promising electrode materials with enhanced specific capacitance, cyclic stability, and capacitance retention for supercapacitor (SC) applications remains a significant challenge. Herein, a three-dimensional (3D) honeycomb-like porous ternary Ni-Co-Mn metal oxide composite electrode material was successfully grown on a carbon cloth (CC) substrate, serving as a promising multifunctional candidate for high-performance supercapacitors. In this design, NiCo and NiMn precursors were first fabricated on the surface of carbon cloth via a facile two-step hydrothermal deposition route, followed by in situ high-temperature annealing to yield a high-performance electrode material. Multiple characterization techniques indicate that the electrode material exhibits a 3D porous structure comprising NiCo 2 O 4 , Ni 6 MnO 8 , NiMnO 3 , and CoMnO 4 , collectively denoted as NC@NM-O. Leveraging the synergistic effects of multiple components and unique structural features, the NC@NM-O electrode delivers an ultra-high specific capacitance of 2517.54 F g −1 at a current density of 1 A g −1 and maintains 90.02% capacitance retention at a high discharge rate of 10 A g −1 after 30,000 cycles. An asymmetric all-solid-state supercapacitor, assembled with an activated carbon (AC) negative electrode (NC@NM-O//AC), achieves an energy density of 68.99 Wh kg −1 and a power density of 827.99 W kg −1 at a working voltage of 1.8 V. After 20,000 cycles, the device maintains an impressive capacitance retention rate of 98.33%. Overall, this work demonstrates that rationally designed, multi-component transition metal oxides can serve as advanced battery-type electrode materials for energy storage devices and provides a promising strategy for the development of next-generation high-performance supercapacitors.

This study addresses key challenges of long-term stability, wide range, and high sensitivity in piezoresistive strain sensors by developing a multilayer composite. A parallel circuit is constructed using carbon nanotube@silver nanoparticles-MXene (CNT@AgNPs-MXene) and expanded graphite (EG) double sensing layers, exploiting EG’s interlayer sliding and recovery capability derived from its wide layer spacing, and is integrated with a thermoplastic polyurethane (TPU) support layer. This design provides complementary current pathways, where a redundant path is offered by the other layer when one layer breaks. The resulting CNT@AgNPs-MXene/EG/TPU trilayer (double sensing layers with a TPU support) achieves stable operation over 150,000 cycles, a working range of 630% (709% mechanically), and a maximum GF of 4091.74. In comparison, the EG/TPU bilayer (single EG layer with a TPU support) is also stable for 150,000 cycles and exhibits a higher maximum GF (16083.30) but a narrower working range (245%). Consequently, each sensor holds a distinct performance edge. The bilayer excels at detecting ultra-fine motions, while the trilayer is advantageous for large-strain scenarios. Both sensors reliably monitor diverse human motions and maintain long-term stability in harsh environments (fresh water, sweat, alkaline/acidic conditions). This work provides a new strategy for high-performance, durable sensors for harsh environments.

To meet the demand for high-sensitivity ammonia (NH 3 ) detection at room temperature, this study develops an ultra-sensitive gas sensor by integrating the exceptional sensing properties of 2D MXene with the evanescent field advantages of optical microfibers. A carboxylated MXene-functionalized microfiber sensor was designed and fabricated. Density functional theory (DFT) calculations confirmed that carboxylation significantly enhances the adsorption energy between the MXene surface and NH 3 molecules compared to pristine MXene, theoretically validating its superior sensitivity. Experimentally, a uniform and robust carboxylated MXene thin film was coated onto the microfiber, demonstrating excellent mechanical stability for practical sensing. Gas sensing tests show a strong linear response within the 10–250 ppm range. Notably, the sensitivity is an order of magnitude higher than previously reported microfiber sensors, with a practical detection limit of 10 ppm and a theoretical limit as low as 6.90 ppm. Furthermore, the sensor exhibits excellent long-term stability over a 10-day measurement and gas selectivity. This research provides a new strategy for developing high-performance room-temperature gas sensors with significant potential for environmental atmospheric monitoring.

A novel Schiff Base as a flame-retardant monomer (FSB, 5-((3,5-bis(trifluoromethyl) benzylidene) amino) isophthalic acid) with -CF 3 was designed and used to synthesize FSB n PETs (PET copolyester) by copolymerization, which shows good flame retardancy and anti-dripping. The introduction of the –CF₃ group increases the cyclization temperature of the FSB Schiff base unit by suppressing the cyclization reaction through its strong electron-withdrawing effect, which is 350–398 °C, higher than 250–348 °C from the PET copolyesters modified by Schiff Base without -CF 3 , indicating that FSB n PETs exhibits a broadened processing temperature window. And FSB also increased the glass transition temperature (Tg), reduced the melting temperature (Tm) and the crystallizability of FSB n PETs. FSB n PETs possessed good flame retardancy and anti-dripping properties, FSB 10 PET (7.4 mol% of FSB) owned V-0 level of UL-94 and 31% value of LOI without dripping phenomenon. The bond of -C-F had not broken into the air phase to make an obvious influence on the flame retardancy property of FSB n PETs, whose flame retardancy mechanism is still type of the condense flame retardancy. Additionally, in the new preparation process for FSB n PETs, the dicarboxylic acid structure of FSB could speed up the condensation polymerization between the BHET precursors, which could save 50% of the preparation time, showing an exciting economic advantage. The -CF₃ modified Schiff base (FSB) is an effective modifier for PET copolyesters, offering improved processing performance and good flame-retardant properties.

Shape-stabilized phase change materials (SSPCMs) are promising for thermally functional mortars, but slight leakage during mixing and phase transition can degrade the particle–matrix interface and reduce durability. This study developed a surfactant-free interfacial self-assembly route to build a hydrophobic silica shell on diatomite/ n -hexadecane SSPCM particles. The shell increased the particle contact angle from 112.1° to 140.2° and reduced leakage to 0.12% after 4 h at 60 °C. At equal PCM dosage, the shell-modified mortar showed lower water absorption and chloride diffusion and higher compressive strength than mortar with unmodified SSPCM. After 500 thermal cycles between 0 and 40 °C, the shell-modified mortar retained a melting enthalpy of 8.85 J/g with only 1.8% latent-heat loss. Microscopy and nanoindentation indicated a denser interfacial region, showing that a simple mineral shell can improve thermal-storage mortar reliability for building applications.

Metal corrosion causes significant economic losses and safety hazards, underscoring the urgent need for effective, environmentally friendly corrosion inhibitors. In this study, an organic–inorganic composite inhibitor, chitosan–glucose–BN (CS–GL–BN) was developed to protect Q235 mild steel in a 3.5-wt% NaCl solution. The inhibitor was synthesized by first reacting chitosan (CS) with glucose (GL) via a Schiff base reaction between the amino group of CS and the aldehyde group of GL, followed by the incorporation of hydroxylated boron nitride (OH-BN). Electrochemical measurements demonstrated an inhibition efficiency of 89.8% at 200 ppm after 72 h immersion, which was markedly higher than those of pure CS (64.3%) and the CS–GL intermediate (75.8%). The water contact angle on the steel substrate increased to 91.1°, indicating enhanced hydrophobicity, while the surface roughness was reduced to 0.694 μm (compared with 5.318 μm for bare steel). These combined surface modifications effectively hindered the penetration of corrosive agents. Molecular modeling studies further revealed that the N/O heteroatoms contributed to strong adsorption, thereby significantly blocking the access of corrosive species. This work presents a synergistic strategy in which CS is functionalized with a long-chain molecule (GL) and integrated with BN to form a hybrid corrosion inhibitor that exhibits high efficiency and improved sustainability.

Increasing TA2 roughness induces a non-monotonic trend in barnacle settlement • Moderate roughness promotes exploration and protein deposition to enhance settlement • Excessive roughness triggers rapid settlement but limits pheromone dispersal • Surface roughness regulates cyprid settlement even in the presence of biofilm . The widespread use of titanium in marine structures is hindered by its susceptibility to biofouling. As a promising antifouling approach, the rational design of direct surface modification relies on a fundamental understanding of how surface properties regulate the settlement of fouling organisms. Herein, this study investigated the effect of TA2 titanium surface roughness on the settlement process of barnacle cyprids. Increased roughness enhanced the temporary attachment of cyprids through sacrificial bonds and mechanical interlocking of deposited footprint proteins. A moderate roughness increase facilitated more surface exploration and footprint protein deposition, thus likely enhanced the distribution of settlement-inducing protein complex (SIPC, a key settlement pheromone), thereby increasing the final settlement ratio. In contrast, excessive roughness enabled cyprids to locate favorable settlement sites with minimal surface exploration, leading to localized surface inspection, increased footprint protein area, and reduced coverage, which may lead to a concentration-dependent avoidance response and reduced cyprid-protein contact probability, resulting in a plateau in the settlement ratio. Field experiments further confirmed that direct cyprid-substrate contact is a prerequisite for firm settlement even in the presence of biofilm, consistent with the mechanistic insights obtained from laboratory assays. These findings elucidate roughness-dependent exploration strategies of barnacle cyprids and provide a theoretical basis for designing antifouling TA2 for marine applications.

Photocatalytic activation of C–H bonds in biomassderived molecules represents a promising strategy for biomass
upgrading. However, the efficiency of selective C–H bond activation
and oxidation is severely restricted by the sluggish kinetics of photogenerated carriers and the uncontrollable generation of reactive oxygen species. Herein, we delicately dispersed Yb single atoms on
ZnIn2S4 nanosheets that boost the photocatalytic directional activation of C–H in 5-hydroxymethylfurfural (HMF). The optimized
Yb0.8-ZIS achieves a balance between 2,5-diformylfuran selectivity
(99.8%) and production rate (906.6 μmol g–1 h–1
) under ambient
conditions. Mechanistic studies reveal that Yb single atoms not only
effectively modulate the electronic structure of ZnIn2S4 but also
serve as hole extractors, thereby enhancing the separation of photogenerated carriers and the activation of oxygen. Furthermore, the ligand-to-metal charge transfer between Lewis acidic Yb sites and
HMF effectively reduces the electron density of the α-C–H bond, thus accelerating the activation process. This work offers insight
into the rational design of rare-earth single atoms for modulating both charge dynamics and molecular activation in selective C–H
activation and oxidation.

The core–shell FeNPs@Pt shows excellent catalytic activity and stability. • Selective detection via thiol–Michael addition without enzymes or aptamers. • The color development is rapid and convenient, taking only 150 s to complete. • The suppression–recovery mechanism amplifies the signal and enhances sensitivity. In this study, we propose an innovative Acrylamide (AA) detection platform based on platinum-coated magnetic iron nanoparticles (FeNPs@Pt). The introduction of a platinum shell not only preserves the intrinsic catalytic properties of FeNPs but also significantly enhances their structural stability and catalytic activity. Compared with traditional antibody–aptamer-based detection methods, this platform employs a thiol–Michael addition reaction combined with a nanocatalyst-mediated cascade colorimetric process. This approach overcomes key limitations of antibody–aptamer technologies, such as high cost and operational complexity, enabling rapid and low-cost detection of AA. The mechanism involves a specific Michael addition reaction between AA and 2,2′-(ethylenedioxy)diethanethiol (EDT), which mitigates the inhibitory effect of EDT on the catalytic activity of FeNPs@Pt. Subsequently, the addition of 3,3′-dimethylbenzidine (TMB) triggers a colorimetric reaction within 150 s, rendering the result visible to the naked eye. This sensing platform exhibits a linear response over the range of 1–200 μM, with a detection limit as low as 0.63 μM. Notably, the FeNPs@Pt–EDT–TMB-based colorimetric detection platform not only provides an efficient and low-cost method for acrylamide detection but also offers an innovative solution for on-site food safety monitoring, demonstrating significant application potential.
