Intestinal vaccination faces several key challenges, including limited epithelial interaction, inefficient antigen uptake, and insufficient immune stimulation. Here, we developed a virus-inspired oral nanovaccine based on spiky mesoporous silica nanoparticles (VMSNs) functionalized with Rehmannia glutinosa polysaccharide (RGP), a natural polysaccharide with favorable intestinal biocompatibility. The resulting RGP-VMSN showed enhanced intestinal retention and epithelial interaction and was associated with increased antigen accessibility within the mucosal environment, reflected by stronger antigen-associated signals at mucosal immune sites. Using ovalbumin (OVA) as a model antigen, oral OVA@RGP-VMSN vaccination was associated with increased intestinal dendritic cell activation, enhanced germinal center responses, and elevated antigen-specific antibody production, together with coordinated mucosal and systemic immune responses. Furthermore, immunization with a Salmonella enterica serovar Typhimurium lysate-loaded nanovaccine improved protection in a murine challenge model. Overall, this strategy represents a promising platform for oral and mucosal nanovaccine development.

Fiber-assisted fabrication of Polyimide/MXene composite aerogel with lightness. • Excellent thermal insulation that enables infrared camouflage and fire protection. • Outstanding mechanical resilience and superior EMI SE (68.5 dB). • Reliable pressure sensing capability to accurately detecting human motion. Fabricating polymer aerogels that merge high electrical conductivity, mechanical elasticity, and enduring stability is a critical yet demanding objective. In this work, lightweight polyimide (PI)/MXene composite aerogels were synthesized through a straightforward, sustainable method utilizing PI fiber-assisted freeze-drying and subsequent thermal imidization. The resulting aerogels possess a unique segregated architecture, providing exceptional electrical conductivity alongside superior electromagnetic interference (EMI) shielding (reaching 68.5 dB). Owing to their mechanical resilience and high conductivity, these aerogels function as dependable piezoresistive sensors for detecting human activity and physical signals, which can accurately detect pressures as low as 0.04 kPa (at 0.5% strain). Furthermore, their porous nature and minimal thermal conductivity ensure efficient heat insulation, making them promising for thermal regulation and fire safety applications. Overall, this study presents a scalable fabrication strategy and promotes the advancement of multifunctional aerogels for next-generation flexible electronic devices.

Latent fingerprint visualization on complex substrates typically suffers from interference from background patterns and fluorescence. Carbon dots (CDs) with room-temperature phosphorescence (RTP) provide an effective route to eliminate background interference due to their long-lived emission. However, most fingerprint reagents based on phosphorescent CDs are limited to single ultraviolet (UV) lamp excitation, resulting in poor operational flexibility and restricted anti-interference performance on complex substrates. While visible light excitation is safer and more flexible, current visible-light-excited phosphorescent fingerprint powders require tedious multi-step preparation. In this study, CDs with alumina matrix (CDs@Al 2 O 3 ) composite emitting RTP under both visible and UV light excitation is synthesized in situ through one-step calcination. The prepared composite features visible RTP lasting for 12 s and 6 s to the naked eye after 365 nm UV and visible light excitation, respectively. With dual-mode excitation properties, the CDs@Al 2 O 3 is applied to imaging of latent fingerprints (LFPs) on various complex substrates. Additionally, background interference from different substrates is effectively eliminated by flexibly switching the light source, which significantly enhances the contrast and detail resolution of fingerprint images. This strategy simplifies the preparation procedure while greatly improving the applicability and reliability of latent fingerprint development in complex scenarios, providing a facile and versatile approach for background-free visualization of LFPs.

Co-loaded CNT with high Co 2+ content of 61.07% exhibited enhanced nanozyme activity. • P2 possessed a safe Co-ion release content far below the threshold of 20 ppm. • P2 exhibited good well-rounded properties and excellent anti-inflammatory activity. Excessive reactive oxygen specie (ROS) is not conducive to bone repair, which is prone to generate during the initial hematoma inflammatory phase following poly( L -lactic acid) (PLLA) bone scaffold implantation and the potential inflammation caused by its acidic degradation products. This study proposed introducing cobalt (Co)-based nanozyme into the PLLA scaffold, and focused on improving the dispersion between nanozyme and the PLLA matrix as well as enhancing the activity of nanozyme itself for efficiently scavenging ROS. The Co was loaded on the surface of carbon nanotube (CNT) for achieving uniform dispersion, and then calcined under different atmospheres for enhancing nanozyme activity via regulating the Co 2+ /Co 3+ ratio and optimizing the electronic structure. It was found that the nanozyme that was calcined in an N 2 atmosphere followed by phosphorylation exhibited a superior ROS-scavenging ability, which was attributed to its high Co 2+ content of 61.07% that facilitating the redox cycling and the optimization of its electronic structure by P doping. As a result, the composite scaffold (P2) at a nanozyme loading of 2 wt% possessed superior intracellular ROS-scavenging ability and downregulation of key inflammatory cytokines compared to the pure PLLA scaffold. It also possessed good cytocompatibility for cell adhesion and proliferation, and exhibited upregulated expression of the pro-angiogenic VEGF factor.

Photothermal superhydrophobic coatings hold great potential for anti-icing/de-icing, but are severely limited by strong dependence on solar illumination and poor stability in dark or low-light environments. Herein, a multifunctional superhydrophobic coating reinforced with dual‑shell phase‑change microcapsules (n‑OD@PDA) is fabricated for synergistic passive anti‑icing and active de‑icing applications. The microcapsules consist of an n-octadecane core for latent heat storage, a SiO₂ inner shell for structural stability, and a polydopamine outer shell enabling broadband photothermal conversion. Incorporated into a fluorinated epoxy matrix, the resulting coating exhibits a hierarchical micro-/nanostructure with excellent superhydrophobicity (Contact angle 151°, Sliding angle 2°). Under 1 Sun irradiation, the coating rapidly heats to 63°C, representing a 96.3% enhancement compared with PDA-free systems. Owing to the phase-change heat storage and release, stable thermal regulation is maintained even under weak or no illumination. At -20°C, the freezing time of water droplets is prolonged by approximately 25 times, and the coating possesses ultra-low ice adhesion strength (10-15 kPa) and rapid de-icing/defrosting performance. This work provides a promising all-weather strategy for high-efficiency anti-/de-icing coatings in harsh low-temperature environments.

Resolving the intrinsic trade-off between interfacial strength and toughness in carbon fiber reinforced polymer composites (CFRPs) remains a central challenge for achieving reliable structural performance. Inspired by the hierarchical brick-and-mortar architecture of nacre, we engineer a coordination-interlocked hybrid coating on carbon fiber surfaces through a layer-by-layer assembly strategy, integrating rigid reduced graphene oxide (rGO) nanosheets as “bricks” with flexible metal-phenolic networks (MPNs) as “mortar.” This bioinspired interphase simultaneously reconstructs the interfacial chemistry and mechanical architecture, establishing a graded modulus transition that facilitates efficient stress transfer. Meanwhile, it activates multiscale energy-dissipation mechanisms, including crack deflection, as well as possible Fe-O bond breakage and interlayer sliding and friction. Consequently, the interfacial shear strength and interfacial fracture toughness increase by 122.3% and 376.1%, respectively, relative to untreated composites. Systematic component substitution demonstrates that only the coordination-interlocked configuration that synergistically couples rigid nanofillers with flexible MPNs achieves concurrent strengthening and toughening, underscoring the critical role of mechanical complementarity and structural confinement within the interphase. Beyond mechanical enhancement, the conductive hybrid architecture reconstructs surface impedance and polarization-active interfaces, enhancing conduction loss and interfacial polarization relaxation to deliver an electromagnetic interference shielding effectiveness of 26.3 dB in the X-band. This work establishes a biomimetic and multifunctional interfacial engineering strategy for structure–function integrated CFRPs.

The necessity for high-efficiency, low-power room-temperature (RT) ammonia (NH3) sensors is particularly acute in environmental monitoring, industrial safety, and medical diagnostics. However, conventional chemiresistive sensors frequently require elevated temperatures to initiate reactions, leading to high energy consumption and potential safety risks. Inspired by plant photosynthesis, this paper successfully designs a ternary S-scheme heterojunction for a photo-activated RT NH3 sensor. The design effectively mimics the efficient charge transfer process in photosynthesis, thereby significantly promoting the separation and migration of photogenerated carriers and enhancing the sensing performance. Experimental results demonstrate exceptional performance under illumination: a high response value of 1679% (representing a 20-fold improvement over the dark state), rapid response and recovery times of 2.1 s and 1.9 s, respectively, along with outstanding selectivity, excellent stability, and a detection limit as low as 17 ppb. This work demonstrates a novel, efficient RT photo-activated NH3 sensor and provides innovative insights into designing biomimetic, smart gas-sensing materials and devices.

Proton exchange membrane water electrolysis (PEMWE) is an environmentally friendly and efficient technology for hydrogen production, playing a vital role in mitigating the fossil energy crisis and bridging renewable energy generation with hydrogen utilization. This work investigates an Ir 0.5 Ru 0.5 nanocluster supported on the nitrogen-vacation-rich niobium nitride (Ir 0.5 Ru 0.5 /NbN) for acidic oxygen evolution reaction (OER). Through defect engineering, the electron cloud density of Ir 0.5 Ru 0.5 active sites is precisely modulated, thereby reinforcing strong metal-support interaction (SMSI) at interfaces. Concomitantly, Ir 0.5 Ru 0.5 nanoclusters with high-density grain boundaries induce local charge rearrangement and orbital hybridization for precise d -band center downshift, are fabricated via a doping strategy, thereby accelerating the intrinsic reaction kinetics of OER. The Ir 0.5 Ru 0.5 /NbN catalyst exhibits excellent OER performance, achieving a low overpotential of 228 mV at 10 mA cm −2 and high stability, maintaining activity for 700 h without degradation. In addition, it presents outstanding performance as an anode in PEMWE with a cell voltage of 1.79 V at 2 A cm −2 . This work provides a viable and efficient approach to reduce Ir loading in PEMWE dramatically, offering a prospective strategy for the cost-effective generation of green hydrogen.

Myocardial infarction (MI) creates a hostile microenvironment characterized by oxidative stress, inflammation, fibrosis, and electrical conduction block, posing a multifaceted challenge for tissue repair. To address this, we developed a multifunctional hydrogel (Gel-PDZC), through an artificial neural network (ANN)-guided optimization process, incorporating nanoparticles comprising a ZIF-8@CaO 2 core for sustained oxygen release, a polydopamine (PDA) interlayer for adhesion and antioxidant activity, and a conductive poly(3,4-ethylenedioxythiophene) (PEDOT) shell. The hydrogel exhibits a unique “adhesion-electrocoupling” effect, where robust tissue adhesion facilitates a pseudocapacitive charge injection mechanism. This not only enables active electrical intervention in the avascular scar but also leverages the endogenous myocardial electric field to restore the hydrogel's antioxidant properties. In a rat MI model, the Gel-PDZC hydrogel comprehensively remodeled the myocardial interstitial microenvironment. It alleviated hypoxia, reduced oxidative stress and apoptosis, suppressed pro-inflammatory C-C motif chemokine receptor 2 (CCR2 + ) macrophages recruitment and promoted electrical coupling between resident CCR2 − macrophages and cardiomyocytes (CMs), inhibited fibroblast-to-myofibroblast transition via the PI3K/AKT pathway, and stimulated angiogenesis. These coordinated cellular and molecular changes translated into substantial functional recovery, evidenced by restored epicardial electrical propagation, improved electromechanical coupling, and a significant increase in cardiac function. Our findings demonstrate that this ANN-optimized, adhesive-electrocoupling hydrogel provides a comprehensive and synergistic solution for repairing the infarcted heart.

Passive cooling material presents a zero-energy solution to the rapidly increasing global demand for cooling. However, these materials face energy/resource-intensive and pollution-intensive manufacturing, posing significant challenges to scalability and long-term energy-saving applications. Here, biosynthesized bacterial cellulose (BC) with a 3D interconnect porous structure was employed as a versatile template to develop an BC-based bilayer passive cooler. The cooler consists of a methyltrimethoxysilane-modified hydrophobic BC (mBC) aerogel and a carboxymethyl cellulose-reinforced hydrophilic BC (cBC) adsorptive material named mBC@cBC. This forms an asymmetric interfacial structure with a hydrophobic radiative layer and a hydrophilic evaporative layer. Owing to the synergistic coupling of radiative and evaporative cooling, the mBC@cBC cooler achieves a sub-ambient temperature drop of 11.1°C on a clear day under 760 W·m −2 solar irradiation. Furthermore, it enables a remarkable temperature reduction exceeding 55°C on high-temperature surfaces (80°C). The cooler is broadly applicable to low-temperature storage, food preservation, and cold-chain logistics. This work addresses the challenges of low-carbon manufacturing and scalability in passive cooling materials and provides an innovative solution for sustainable and environmentally friendly cooling technologies.

Bacterial decomposition of sweat produces odors affecting close-fitting garment comfort. This study selected five polyester filament types: coffee carbon polyester filament (CC-PET), bamboo charcoal polyester filament (BC-PET), oyster shell polyester filament (OS-PET), graphene polyester filament (GR-PET), and conventional polyester filament (C-PET). These four yarns exemplify three mainstream deodorizing mechanisms: BC-PET relies on physical adsorption through its porous structure; CC-PET combines adsorption with antibacterial moisture management to suppress odor at the source; GR-PET and OS-PET inhibit bacteria via reactive radicals from oxygen-containing groups and calcium oxide, respectively. Three structures were tested: weft flat knit, 1 × 1 rib, and 1 + 3 false rib. 1 + 1 rib and 1 + 3 false rib differ markedly in elasticity, thickness, and hand. Plain jersey is smooth, soft, and breathable with good extensibility. 1 + 1 rib delivers superior transverse elasticity and dimensional stability. 1 + 3 false rib is loftier and stiffer with enhanced shape retention and thermal insulation. Fifteen specimens were knitted on a seamless circular machine and evaluated using ammonia adsorption rate and acetic acid adsorption rate. Results show that fiber type significantly influences deodorizing performance, with the graphene polyester filament with the 1 + 3 false rib structure achieving the best adsorption for both gases. This provides a theoretical foundation for deodorizing functional fabric development.

Efficient seawater oxygen evolution requires electrocatalysts that combine high activity, chloride tolerance, and long-term durability. Herein, a phosphorus–lignin ligand strategy is developed to construct an activation-prone P-CoMoO 3 @PLC precatalyst. Phosphorylated lignin enables homogeneous Co/Mo coordination, lattice P incorporation, oxygen-vacancy generation, and conductive carbon confinement, producing a metastable CoMoO 3 lattice with perturbed Co-P-Mo/Co-O-Mo coordination environments. P-CoMoO 3 @PLC requires only 180 mV at 10 mA cm −2 in simulated seawater, and sustains 500 mA cm −2 in natural seawater, outperforming commercial RuO 2 in durability. Operando analyses reveal an activation-induced dissolution–reconstruction pathway, in which partial Mo/P leaching converts the precatalyst into a Co(OH) 2 -derived CoOOH-rich interface coupled with residual CoMoO 4 . Co(OH) 2 -like species serve as hydroxylated intermediates, whereas CoOOH-like sites constitute the active OER phase; residual CoMoO 4 and the lignin-derived carbon matrix stabilize the reconstructed layer and promote charge transport. DFT calculations further show favorable *OH formation but thermodynamically unfavorable *Cl adsorption, explaining the preferential OER pathway and suppressed chlorine-related reactions. This work establishes bio-ligand metastability and reconstruction-driven interface engineering as a robust design strategy for seawater electrolysis.
