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.

In this work, a high-performance sensor based on a multimode fiber-thin core fiber-multimode fiber (MMF–TCF–MMF) structure is demonstrated. By using a continuous Au film and covalently anchored AgNPs on the TCF surface, the synergistic coupling between exciting surface plasmon resonance (SPR) and localized surface plasmon resonance (LSPR) is realized. Following a systematic optimization guided by COMSOL simulations and experimental validation, the refractive index (RI) sensitivity reached 2525.06 nm/RIU with a figure of merit (FOM) of 9.494 RIU−1, and the temperature sensitivity reached −1.07 nm/°C. The system demonstrated excellent linearity, repeatability, and stability. The proposed sensor effectively merges cost-efficiency with robust precision, showing significant potential for biochemical, environmental, and industrial sensing applications.

Though ionogels serve as a key component of wearable and intelligent sensing systems, they possess several characteristics that constrain their practical applications, including poor electro-mechanical synergy, insufficient interface synergy (resulting in low ion migration efficiency and conductive network fracture under large strains), scarce data labels, and inadequate long-term feature extraction capabilities in recognition systems. To address these issues, a new butanediol diacrylate/acrylic acid‑silver nanowire (BDAA/AgNWs) ionogel was synthesized using 365-nm ultraviolet (UV) polymerization, with 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), 2-acrylamido-2-methylpropane sulfonic acid (AMPS), and acrylamide (AM) as the monomer-ionic liquid system, dimethyl sulfoxide (DMSO) as the solvent, and silver nanowires (AgNWs) as the filler. The ionogel formed a dual conductive network via metal-ionic liquid/monomer chemical coordination, had a conductivity of 1.394 S/m at 386.81% stretch, good stability, and biocompatibility. The outstanding mechanical properties of ionogel enable its use as a highly sensitive strain-resistive sensor. When mounted on the skin, mechanical deformations induced by facial expressions or joint movements stretch the internal conductive network, resulting in predictable and reproducible changes in electrical resistance. These resistance variations are captured via a voltage divider circuit and converted into digital signals through an analog-to-digital converter, providing a stable and reliable input for subsequent intelligent processing. To overcome existing accuracy limitations in motion recognition, an advanced algorithm integrating Transformer-based temporal feature extraction with triplet contrastive learning is employed. This end-to-end sensing-to-recognition framework enables the system to accurately interpret dynamic physiological signals, achieving a facial expression recognition accuracy of 97.62%—a 15% improvement over mainstream algorithms—and a 10% enhancement in action recognition performance. These results establish a robust foundation for the advancement of flexible, wearable intelligent sensing systems and next-generation human-machine interaction technologies.

Introducing methane into the anode of a solid oxide electrolysis cell (SOEC) can substantially reduce the voltage required for hydrogen production, and the presence of H 2 S in the methane will significantly impact the performance of the anodic oxidation. In this study, Ni-loaded Gd-doped CeO 2 (Ni–GDC) is prepared via hydrolysis and impregnation methods, which is used as an anode catalyst of an SOEC under the anode atmosphere of methane with H 2 S. The results show that H 2 S can poison the catalytic oxidization and oxygen evolution active sites on Ni–GDC. The high temperature of 850°C and above enables O 2 on the anode to react with H 2 S to reduce the poisoning of active sites. The H 2 S adsorption on methane oxidation active sites reaches equilibrium under the H 2 S content in the methane anode atmosphere over 400 ppmv. The removal of H 2 S results in partial recovery of methane oxidation active sites at the temperatures above 850°C. Sufficient O 2− under high current density at high temperature can accelerate the oxidation of S species on the active sites, improving the resistance to H 2 S.

Open abdomen (OA) therapy is crucial for managing severe abdominal infections, intra-abdominal hypertension, and trauma but often faces complications like infections and enteric fistulas. To address this, a novel multilayer drug-loaded hydrogel dressing was designed to promote wound healing. The dressing comprises a bottom layer of a carboxymethyl chitosan/aldehyde-modified hyaluronic acid (CC/HA-CHO) hydrogel loaded with Ag nanoparticles (AgNPs) for rapid gelation and broad-spectrum antibacterial action; a middle polyacrylamide (PAAm) gel layer loaded with interleukin-4 (IL-4) to polarize macrophages toward the M2 phenotype for tissue repair; and a top polydimethylsiloxane (PDMS) antifouling layer treated with oxygen plasma for enhanced adhesion and hydrophilicity. Characterization via FTIR, SEM, swelling tests, and drug release assays confirmed the hydrogel's structure, stability, and sequential release of AgNPs and IL-4. In vivo experimental results show that the percentage of wound closure in the drug-loaded hydrogel group reached approximately 30% on day 7, while that in the control group was only about 10%. Thus, the drug-loaded hydrogel can significantly accelerate wound healing of open abdominal wounds. This multifunctional hydrogel combines antibacterial, anti-inflammatory, and tissue-regenerative properties, offering a promising strategy for OA wound management.

Photodetectors (PDs) are currently widely employed in communications, imaging, sensing, and other fields. However, elevated temperatures significantly exacerbate noise effects, thereby degrading device performance and operational lifetime. Notably, the thermal-induced bandgap broadening (TBB) phenomenon in copolymer organic semiconductors (OSCs) offers a promising solution to this challenge. In this work, we diketo pyrrolopyrrole-thieno [3,2-b] thio-phene (DPPT-TT) as the active layer, integrated with metallic nanoparticle nanostructures. Comprehensive characterization confirmed that the TBB effect effectively suppresses dark current under high-temperature conditions. Benefiting from this phenomenon, the device exhibits an ultralow dark current density of $2.44\times 10^{-{10}}$ A/cm2 at 353 K. Under a 0.2 V bias, it achieves remarkable performance metrics, including an external quantum efficiency (EQE) of 71.47% and a theoretical specific detectivity ( ${D}_{\textit {th}}^{\ast }\text {)}$ of $5.12\times 10^{{13}}$ Jones ( $\lambda =780$ nm). To elucidate and quantitatively analyze the physical role of TBB in optoelectronic devices, we established a block filling model (BFM). Through combined molecular dynamics (MDs) simulations and first-principles calculations, this model successfully simulates the physical properties of DPPT-TT and provides a quantitative analysis of temperature-induced bandgap variations. Our experimental investigations systematically analyzed the temperature-dependent flocculent molecular disorder in copolymer OSCs, establishing a theoretical foundation for developing thermally reliable photodetectors. These findings provide crucial insights into high-temperature operation mechanisms and device optimization strategies.

Objectives:Silver nanoparticles (AgNPs) were synthesized via an easy and rapid biogenic synthesis approach, utilizing the dual capabilities of salicylic acid as both a reducing and capping agent.Methods:The characterization of Salicylic Acid-Mediated Silver Nanoparticle (SA-AgNPs) was conducted using a variety of techniques, including ultraviolet-visible spectroscopy, dynamic light scattering, scanning electron microscopy combined with energy dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, as well as thermogravimetric analysis paired with differential scanning calorimetry.Results:SA-AgNPs demonstrated significant antibacterial properties against both Gram-positive (methicillin-resistantStaphylococcus epidermidis,Staphylococcus aureus,Cutibacterium acnes, methicillin-resistantStaphylococcus aureus) and Gram-negative (Escherichia coli), with minimum inhibitory concentrations (MICs) of 8, 9, 8, 4, and 6 μg/mL, respectively. At a concentration of 32 μg/mL, SA-AgNPs exhibited 99.9% killing efficiency againstEscherichia coli(E. coli),Cutibacterium acnes(C. acnes), and methicillin-resistantStaphylococcus aureus(MRSA), within 4, 16, and 12 h, respectively. At the same concentration, SA-AgNPs effectively inhibited 95.61% of MRSA biofilm formation. SA-AgNPs induced the leakage of intracellular macromolecular substances by increasing the membrane permeability, which ultimately caused bacterial apoptosis.Conclusions:Overall, this study presents a fast and environmentally friendly approach for synthesizing SA-AgNPs, with potential applications as nano antibiotics antibacterial coatings for implantable medical devices and wound dressings.

Biological nitrogen (N) fixation is an ecological method used to provide nutrition for crops and reduce fertilizer application in terrestrial ecosystems. Silver nanoparticles (AgNPs) are becoming environmental contaminants, and, thus, could negatively affect the activity and diversity of soil diazotrophs. To test this, a greenhouse pot experiment for growing maize was performed under different concentrations of AgNPs (0, 1, 5, 10, 20 mg kg−1). We measured the N2-fixation activity and abundance ofnifHgene encoding the nitrogenase reductase subunit and analyzed the diversity, composition and co-occurrence networks of diazotrophic communities in maize rhizospheric soil. Results showed that a lower dose of AgNPs did not show significant influence on soil diazotrophs, while a higher dose of AgNPs decreased both soil N2-fixation activity andnifHgene abundance, though diazotrophic diversity remained unchanged. AgNPs at 10 mg kg−1and 20 mg kg−1strongly shifted the community composition of diazotrophs, increasing the proportions ofBradyrhizobiumandPaenibacillus,while decreasingAzospirillumandRhizobium.Network analysis revealed weakened negative associations among species under AgNPs, with keystone taxa shifting fromBradyrhizobium,Geobacter,AzospirillumandBurkholderiatoBradyrhizobium,PaenibacillusandSkermanellaunder AgNPs. Soil-soluble Ag, dissolved organic carbon and soil pH were identified as the factors most closely driving the diazotrophic community composition. In conclusion, higher doses of AgNPs could inhibit N2-fixation activity and shape the diazotrophic communities. These findings provide empirical evidence of AgNPs’ ecological impacts on soil microbial functions.

Liquid metal batteries (LMBs) are emerging as a promising energy storage solution owing to their inherent safety, low cost, and long lifespan. Bismuth (Bi) offers excellent cycle stability but is hindered by sluggish electrode kinetics due to the formation of compact and poorly conductive intermetallics at high rates. Here, we construct an electronically networked architecture to overcome this limitation by incorporating little copper (Cu) into a Bi electrode. This innovative design enhances electrical conductivity and reduces the ion diffusion energy barrier, affording dramatically improved electrochemical performance. Our Li‖Bi96Cu4 cell demonstrates superior high-rate capability, delivering 85.50% of the theoretical capacity at 3C, a substantial improvement compared to 57.50% of the Li‖Bi cell. Furthermore, it exhibits unprecedented cyclability without noticeable capacity degradation over 4000 cycles, a performance unparalleled by other reported LMB chemistries. This facile and effective Cu doping modification provides a transformative approach to enhance Bi electrode kinetics, offering a new paradigm for advanced electrode design for LMBs.

Reliable ceramic-metal joining is essential for the construction of protonic ceramic fuel cell (PCFC) stacks, yet joint failure still occurs on the electrolyte ceramic side. For the first time, this study proposes a femtosecond laser-enabled multiscale interface engineering strategy to promote the sintered-joining between BaZr 0.4 Ce 0.4 Y 0.1 Yb 0.1 O 3-δ electrolyte and Crofer 22 APU interconnect. The method enables the formation of microscale grooves (15 μm width and 2.5 μm depth), nanoscale clusters (ranging from several tens to hundreds of nanometers), and oxygen vacancies (concentration increased by 100 %) at a laser power of 12 mW. The resulting hierarchical interface architecture markedly promotes effective sintering of the micro-Ag particle interlayer. Under optimized conditions (930 °C, 1 MPa, 30 min), the resulting joints are defect-free and exhibit exceptional durability in humid oxidative environments. The shear strength reaches 42.8 MPa, representing a 97 % improvement over untreated samples. The multiscale enhancement mechanism is systematically elucidated. First-principles calculations further reveal a novel atomic-scale joining mechanism: laser-induced oxygen vacancies trigger localized Jahn-Teller distortion of the crystal field, thereby enhancing the d-p orbital hybridization between the coordinating O and Ag. This femtosecond laser-driven interface engineering strategy offers a robust and scalable solution for high-performance ceramic-metal integration in advanced energy systems.

Smart windows, which can intelligently regulate indoor temperature and improve living comfort provide a promising solution for reducing building energy consumption. Active and passive smart windows have their own advantages and disadvantages, yet it is a challenge to perfectly combine the two to achieve complementary advantages. In this work, photo- and electrical dual-responsive films containing WO 3 , ethylene glycol (EG), and Ag are prepared, which can simultaneously realize photochromism and electrochromism. The EG and silver nanowires synergistically broaden the photoresponsive and electrochemical activities of the films and promote the electron transfer within the films and the interfacial ion transport. The WO 3 -EG-Ag films exhibit an excellent dual-band (visible (vis) light and near-infrared (NIR) light) modulation capability (700 nm, 75.9%; 1000 nm, 76.7%; and 2000 nm, 69.2%), a fast responsive speed, and good reversibility. Finally, an all-solid-state photoelectric dual-responsive smart window with four operating modes (photochromic bright-cooling, photochromic dark-cooling, electrochromic bleaching, and photochromic self-bleaching) is assembled. The multiple operating modes can satisfy various individual demands of different people and also provide a more energy-saving and intelligent modulation of indoor temperature. This work provides a new direction for the development of next-generation smart windows.

Decompressive craniectomy (DC) is a commonly used life-saving neurosurgical procedure but always accompanied by a severe case of temporalis damage and even adhesions with the dura mater, which may lead to irreparable serious consequences. A suitable material for repairing the damage and preventing adhesions is urgently needed. However, existing materials mostly struggle to meet the clinical demands. In this paper, we introduce a novel siloxane nanocomposite: Ag-Quercetin-Polysiloxane (AQS), to effectively avoid the irreparable serious consequences caused by the cases after DC. AQS has many excellent properties, including flexibility, hydrophobicity, recyclability, low cost, and especially the anti-inflammatory and broad-spectrum antibacterial. Comprehensive experiments were conducted to verify the critical role of AQS, demonstrating a superiority of the AQS in various aspects. In vitro experiments, AQS possessed broad-spectrum antimicrobial activity, effective anti-adhesion properties against multiple cell lines, and the slow-release profile of Ag and quercetin. In vivo experiments, AQS effectively prevented adhesions between the temporalis muscle and dura mater, reduced pro-inflammatory IL-6 secretion, increased anti-inflammatory IL-10 and pro-healing PCNA production, thereby promoted temporalis remodeling. Furthermore, AQS exhibited excellent biocompatibility both in vitro and in vivo experiments. This nanocomposite may provide a novel therapeutic strategy for addressing the repairment and adhesion problems of temporalis muscle following DC.
