Commercial airway stents often slip and deform, leading to severe complications such as mucosal injury, granulation tissue formation, and stent migration, which can cause recurrent airway obstruction and necessitate repeated interventions. Here, we introduce a 3D-printed tracheal stent composed of continuous bamboo fiber reinforced shape memory polylactic acid (BF/SMP). These naturally derived fibers (tensile strength ~ 1.90 GPa, modulus ~ 91.30 GPa) exhibit excellent mechanical resilience. Following an instantaneous thermal treatment, their interfacial compatibility with SMP is notably improved. The 30% BF/SMP stent can undergo over 1,000 three-point bending cycles under a 20 N load, with a bending deflection of 30.85%. In vitro, it promotes bronchial epithelial cell proliferation. Preliminary animal studies suggest that the biomass-based stent provides airway support without causing significant inflammation or organ abnormalities. Overall, this work demonstrates a biomass-reinforced, thermally deployable airway stent concept and provides a foundation for future studies on catheter-compatible delivery and long-term in vivo performance.

The development of high-performance nanocomposites critically depends on effective interfacial coupling agents, with multifunctional variants offering particular promise. Herein, we propose the rational design and synthesis of a multifunctional silane coupling agent via covalent organic framework (COF) self-assembly. This agent (COF-APTES) integrates a high density of amino groups and ethoxy silane terminals within a porous, thermally stable architecture. We demonstrate its application in grafting onto nano-SiO₂ to fabricate a modified filler (SiO₂-COF-APTES) for reinforcing epoxy composites. Comprehensive characterization reveals that the COF-APTES enhances the epoxy-filler interface through a synergistic mechanism: its abundant amino groups enable robust covalent bonding with the epoxy matrix, while its porous structure provides physical interlocking and promotes the formation of an interpenetrating network. Consequently, composites reinforced with SiO₂-COF-APTES exhibit a 71% increase in tensile strength and a 42% increase in shear strength compared to those with unmodified SiO₂. This work demonstrates that the COF self-assembly strategy can serve as a feasible approach for designing multifunctional coupling agents, providing a potential pathway to improve the interfacial properties and mechanical performance of polymer nanocomposites.

Perfluorooctanoic acid (PFOA) has attracted growing attention due to its widespread occurrence and harmful effects on humans. Owing to the strong C F bonds that confer inherent stability on PFOA, achieving efficient degradation via traditional photocatalysts is highly challenging. In this study, a UiO-66-NH 2 photocatalytic-persulfate (UiO-66-NH 2 /PS) integrated system was constructed to achieve high-efficiency PFOA removal, and its underlying mechanism was systematically revealed. A zirconium-based metal–organic framework, UiO-66-NH 2 , with readily tunable porosity was successfully synthesized via a solvothermal route, and its crystal structure, microstructure, and optical absorption behavior were confirmed through comprehensive characterizations. After optimization of the reaction parameters, the UiO-66-NH₂/PS system exhibited excellent PFOA degradation performance, with a markedly enhanced removal efficiency relative to the single UiO-66-NH 2 or persulfate system. The degradation efficiency of UiO-66-NH 2 /PS system in degrading PFOA was affected by ubiquitous anions and humic acid in water. Investigation of degradation pathways revealed that the cooperative action of photogenerated holes and SO₄• − /•OH radicals progressively cleaved the recalcitrant C F bonds, with short-chain perfluorocarboxylic acids (PFCAs) including perfluoroheptanoic acid (PFHpA, C 6 F 13 COOH), perfluorohexanoic acid (PFHxA, C 5 F 11 COOH), perfluoropentanoic acid (PFPeA, C 4 F 9 COOH), and perfluorobutyric acid (PFBA, C 3 F 7 COOH) identified as the main degradation intermediates. This study proposed a high-efficiency, economical and eco-friendly approach for the mineralization of PFOA, and meanwhile shed new light on the mechanism underlying the efficient degradation of PFOA by UiO-66-based photocatalysis combined with persulfate activation.

This study proposes a semi-open low-temperature plasma ambient ionization source coupled with ion mobility spectrometry for in situ analysis of multiphase samples. For the first time, a bidirectional plasma jet configuration is introduced into the IMS system, enabling the dielectric barrier discharge device to simultaneously generate an ionization jet and a transport jet. The ionization jet efficiently ionizes external samples, while the transport jet stably delivers the ionized products into the reaction region of the ion mobility spectrometer. The coordinated action of the two jets creates a plasma-rich ionization and transfer environment between the sample surface and the IMS inlet, effectively suppressing ion neutralization and ion loss, thereby enhancing signal intensity and detection sensitivity. To further optimize ion transmission, the semi-open ionization source is vertically coupled to the reaction region of the ion mobility spectrometer, which helps reduce direct intrusion of neutral gas into the drift region and improves signal stability. The system enables in situ detection without complex pretreatment, reducing background interference and improving the signal-to-noise ratio. Experiments demonstrate rapid detection of analytes including triethylamine, dimethylformamide, acetaminophen, caffeine, acetone, and ethanol, with clear separation between the reactant ion peaks and the analyte peaks. These results confirm the feasibility and application potential of the semi-open bidirectional low-temperature plasma dielectric barrier discharge ion mobility spectrometry system for rapid in situ detection of multiphase samples, providing a promising approach for environmental monitoring, public safety, food safety, and pharmaceutical analysis.

This work successfully synthesized and empirically evaluated the F-doped Prussian blue analogues (PBA) deposition of FePO 4 (FPO) on the nickel foam (NF). The PBA/NF cubic structure was hydrothermally grown on the Ni-MOF/NF precursor and encapsulated by electrodeposited FePO 4 spheres, leading to the final F-PBA@FPO/NF. The catalyst serves as a high-performance bifunctional electrocatalyst, delivering low overpotentials of 220 mV for the OER and 174 mV for the HER at 10mA cm −2 , coupled with favorable Tafel slopes of 144 and 130.9 mV dec −1 , respectively. The catalyst was doped with a large number of F atoms, which formed abundant hydrogen bonds with water, thereby promoting the generation of HER. The substantial formation of Ni-F bonds during the testing stage created a modified local coordination environment, thereby establishing a foundation for the continuous in-situ formation of active NiOOH phases under operating conditions. Interestingly, F doping plays a dual role: it tailors the electronic structure of metal centers and induces in-situ etching of the material, thereby generating structural openings during the electrochemical process. This work advances the fundamental understanding and rational design of F-doped catalysts and bifunctional electrocatalysts for hydrogen production.

The photocatalytic conversion of nitrate (NO 3 − ) to ammonia (NH 3 ) represents a dual-benefit strategy for environmental remediation coupled with the recovery of a valuable chemical feedstock. In this work, we demonstrate that boron-doped black titanium dioxide materials (B x -TiO 2 ), synthesized using closo -dodecaborate dianion ([ closo -B 12 H 12 ] 2− ) as the boron (B) source, serve as efficient catalysts for photoreduction of NO 3 − to NH 3 in aqueous media under visible-light irradiation. B doping induces the formation of an amorphous phase in TiO 2 , which optimizes surface properties, narrows the band gap, and extends the optical absorption spectrum from the ultraviolet to the visible region—resulting in a significant enhancement in light utilization efficiency. Density functional theory (DFT) calculations reveal orbital hybridization between Ti and B, confirming their synergistic catalytic role. Among the series of synthesized materials, B 1 -TiO 2 exhibits the highest catalytic activity, achieving an ammonia production rate of 769.0 μmol g cat −1 h −1 , which compares favorably with previously reported systems. This work on heterogeneous B doping is expected to serve as a reference for the development of efficient catalysts in follow-up studies.

Constructing iron-nitrogen-carbon (Fe- N -C) catalysts with high intrinsic activity for the oxygen reduction reaction (ORR) remains challenging. Meanwhile, additional structural optimization is necessary to improve mass transport and attain higher power density for practical applications. Herein, using silicalite-1 zeolite as a template, we employed a region-selective strategy to construct iron-embedded hollow-out nitrogen-doped carbon nanoboxes (Fe- N -HOCNs) catalyst with coexisted Fe-N x and Fe nanoclusters, and as an efficient ORR electrocatalyst for the zinc-air batteries (ZABs). Despite the Fe content of 4.73 wt% in Fe- N -HOCNs, it exhibits a high half-wave potential ( E 1/2 = 0.87 V), excellent mass activity ( j m , 658.17 mA mg −1 ), and turnover frequency (TOF, 0.3808 e − site −1 s −1 ), with ORR performance surpassing that of commercial Pt/C. This is attributed to the synergistic effect of coexisting Fe-N x and Fe nanoclusters, which effectively lower the energy barrier of the ORR, optimizes the adsorption of reaction intermediates, and enhances electronic conductivity. Moreover, the abundant short-range, penetrable microporous/mesoporous channels overcome the diffusion limitations of O 2 , significantly improving electrochemical wettability, accessibility, and utilization efficiency of the limited catalytic active sites, facilitating the exposure of active sites at the three-phase boundary. Finite element simulations reveal that the multidirectional hollow-out structure of Fe- N -HOCNs functions as interconnected pathways, substantially reducing O 2 transport resistance within the cathode catalyst layer. In ZABs, Fe- N -HOCNs enable the device to achieve a power density of 164 mW cm −2 and a specific capacity of 776 mA h g −1 , along with excellent rate performance.

Photothermal therapy (PTT) not only directly eliminates tumors through its photothermal effects but also triggers a critical antitumor immune response. This study created a multifunctional nanoplatform out of biodegradable mesoporous polydopamine (mPDA). By doping manganese ions (Mn 2+ ) to generate mPDA@Mn nanoparticles, the material's photothermal conversion efficiency was greatly improved, as was the efficient loading of the anticancer medication carfilzomib. This system enables precise control over the release of CFZ and Mn 2+ under near-infrared (NIR) irradiation, achieving triple synergistic antitumor effects through chemotherapy, photothermal therapy, and immune activation at the tumor site. In vitro experiments demonstrated that the cell membrane-coated CM@mPDA@Mn/CFZ nanosystem exhibits favorable biocompatibility. In a mouse model of multiple myeloma, the combination of this nanosystem with NIR irradiation showed significant synergistic therapeutic efficacy. It not only destroyed tumor cells directly, but it also stimulated dendritic cell (DC) maturation, CD3 + T cell activation, and cytotoxic T lymphocyte (CTL) infiltration, substantially modifying the tumor immune microenvironment. These findings suggest that this triple synergistic method, which combines chemotherapy, photothermal ablation, and immune activation, provides an effective and targeted nanotherapeutic platform for the treatment of multiple myeloma.

Polyvinylidene fluoride (PVDF) and its copolymer-based piezoelectric composites are widely used in piezoelectric sensors to facilitate efficient energy conversion due to their flexibility and high electromechanical coupling properties. In this study, we introduce a piezoelectric nanogenerator (PENG) that utilizes BaTiO 3 –Nb 2 O 5 @PDA@MWCNTs/P(VDF-TrFE) composite films (BNP-MCP) for detecting environmental mechanical stimuli and enabling wireless monitoring. Notably, adding 5 wt% BaTiO 3 –Nb 2 O 5 @PDA@MWCNTs increases the dielectric constant (εᵣ)of BNP-MCP to 21.8 from the 14.8 of pristine P(VDF-TrFE) at 100 Hz, thereby enhancing the PENG's output performance by improving the charge density. By optimizing the BaTiO 3 –Nb 2 O 5 @PDA content in the P(VDF-TrFE) matrix, the fabricated PENG is characterized by an output voltage of 7.5 V and a maximum power density of 4.52 μW cm −2 . This optimized PENG maintains stable performance after 4500 bending-releasing cycles and exhibits high sensitivity in detecting diverse mechanical stimuli, spanning from subtle perturbations (e.g., leaf fall and insect crawling) to intense impacts (e.g., water flow and human jumping). Additionally, an autonomous all-weather rainfall monitoring system leverages wirelessly received piezoelectric signals to trigger real-time precipitation alerts with three-tier warning thresholds: light rain, moderate rain, and heavy rain. This study establishes a sustainable monitoring framework for agricultural and environmental applications, advancing next-generation self-powered sensing technologies.

Developing a biomimetic surface with non-wetting properties, durability, and smart self-healing properties, influenced by pitcher plants. In this study, the Smooth Liquid-Infused Porous Surface (SLIPS) with liquid repellency was prepared on the Magnesium alloy, combining various techniques such as anodizing, boiling and chemical modification. The results demonstrate that the resulting coated surface exhibits not only excellent antifouling, self-recovery, and stability, but also excellent adhesion strength with substrate, providing a multifunctional protective barrier for the Magnesium alloy. SLIPS maintains corrosion resistance and restores superhydrophobicity as needed., benefiting from its self-healing function, and the self-recovery process of SLIPS was simulated by Large-scale Atomic/Molecular Massively Parallel Simulator theory.

The extensive utilization of superhydrophobic wood is currently impeded by the poor durability of coatings and the reliance on toxic low-surface-energy chemicals. Herein, a fluorine-free superhydrophobic coating was developed, and consequently, a superhydrophobic wood with comprehensive robustness was fabricated based on this formulation. Specifically, the essential surface roughness was created using SiO 2 particles. Cellulose nanofibrils (CNFs) were incorporated simultaneously as a dispersant and a reinforcing phase, suppressing particle agglomeration and enhanced the durability of the superhydrophobic wood. Furthermore, low-surface-energy modification utilizing hexadecyltrimethoxysilane (HDTMS) and polydimethylsiloxane (PDMS) were implemented to achieve hydrophobic grafting at the molecular level and cross-linked encapsulation at the macroscopic scale. Through the synergistic design that integrates mechanical reinforcement of CNFs, chemical inertness with minimized surface energy of HDTMS/PDMS, and hierarchical surface architectures of SiO 2 , the superhydrophobic performance of wood was systematically optimized across the physical, chemical, and structural dimensions. Specifically, the surface exhibited superhydrophobicity with a static contact angle of 157.6° and a sliding angle of 6.3°. The material also demonstrated excellent durability, maintaining its superhydrophobicity after prolonged exposure to harsh conditions, including saltwater immersion (96 h), chemical corrosion (pH = 2–12), sandpaper abrasion (200 cm under 100 g), tape peeling (200 cycles), UV aging (216 h), and outdoor exposure (25 days). This durability arises from the synergy between its chemically stable components and reinforced micro-nano structure, in which nano-SiO 2 particles play a key role in enhancing UV resistance by absorbing and scattering radiation to prevent polymer photo-oxidation. The coating also demonstrated broad substrate universality, performing effectively on diverse materials such as paper, cotton, glass, wood, and metals, highlighting its potential as a universal superhydrophobic solution. In summary, this work presents a scalable, eco-friendly strategy for creating durable, high-performance superhydrophobic wood, paving the way for next-generation materials.

In this study, we developed catechol-imprinted magnetic molecularly imprinted polymers (Ca-DFFPBA-MMIPs) via a dual-affinity strategy combining boronate affinity and a two-step template immobilization protocol. The Ca-DFFPBA-MMIPs exhibited high affinity and selectivity for catecholamines (norepinephrine, epinephrine, and dopamine) under neutral conditions. The adsorption capacity reached a plateau at pH 6.5–7.0, and the adsorption time was optimized to 40 minutes. The MMIPs showed excellent selectivity for the target catecholamines over structurally related interferents. The Ca-DFFPBA-MMIPs also demonstrated good reusability, retaining ≥90% of their initial adsorption capacity after seven consecutive cycles. The analytical performance of the Ca-DFFPBA-MMIPs was validated in terms of linear range, coefficient of determination (R²), limit of detection (LOD), limit of quantification (LOQ), and intra- and inter-day precision (RSD). The LODs were 12–31 ng mL⁻¹ and LOQs were 40–103 ng mL⁻¹, with RSDs of 0.87–1.13% (intra-day) and 1.75–1.95% (inter-day). The Ca-DFFPBA-MMIPs were successfully applied to the selective extraction of catecholamines from equine urine (enrichment factors of 18–27), with recoveries ranging from 64.5% to 105.7%. This study provides a new approach for the analysis of catecholamines in complex matrices and highlights the potential of Ca-DFFPBA-MMIPs as a practical nanosorbent for efficient and selective enrichment of catecholamines and related compounds.
