In nanomaterials containing multiple metal atoms, interactions between metal atoms can generate the Fenton effect, making them a novel antibacterial agent that combines photodynamic and chemodynamic properties. However, conventional single-atom or multi-atom nanomaterials are limited by their specific surface area and porosity, resulting in relatively low photocatalytic efficiency. Herein, we developed a nanzyme antibacterial agent based on a porous ZIF-8 metal-organic framework incorporated with Pt and CuS via a straightforward method. Under low-concentration near-infrared (NIR) light irradiation, the CuS enables the nanzyme to rapidly raise the reaction system temperature to about 50 °C within 5 min. Furthermore, facilitated by charge transfer between Cu and Pt metals and the prominent Fenton-like activity of Pt, the system efficiently catalyzes hydroxyl radical generation from trace amounts of H 2 O 2. This mechanism synergistically integrates photodynamic and chemodynamic actions for antibacterial efficacy. The designed CuS@Pt@ZIF-8 nanzyme achieves a bacterial elimination rate of over 95% against common bacteria when subjected to irradiation with 808 nm NIR light. In vivo experiments in mice demonstrated a wound healing rate of up to 98% within 7 days. Additionally, experiments on plants and animals demonstrated that this nanzyme has minimal toxicity. The broad-spectrum Fenton-like catalytic system provide an efficient strategy for drug-resistant bacterial wound infections under combined photodynamic and chemical dynamics therapy, offering a new avenue for the development of clinical drugs.

Traditional flexible conductive hydrogels use water as the dispersion medium, making them prone to freezing and cracking in low-temperature environments, rendering them unusable. Therefore, developing flexible materials that combine freeze resistance with high electrical conductivity to meet the demands of signal monitoring and energy storage in severe cold conditions is crucial for expanding the application boundaries of flexible wearable devices. This paper reports an effective strategy for preparing a flexible, freeze-resistant, and highly conductive polyzwitterionic eutectogel based on renewable nanocellulose. This strategy utilizes a three-dimensional cellulose network constructed via ionic crosslinking as the functional filler framework. Sulfonated betaine zwitterionic DMAPS ([2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide) is then in situ polymerized within this network to produce a dual-network composite eutectogel featuring both physical and chemical crosslinking interactions. The uniformly coexisting cellulose-Al 3+ network and polyzwitterionic network provide the structural foundation for energy dissipation and ion migration. Consequently, eutectogels exhibits excellent tensile properties and high electrical conductivity (0.25–0.71 S·m −1 ). The incorporation of deep eutectic solvents (DES) endows gels with exceptional antifreeze properties, maintaining excellent stability and outstanding ionic conductivity (0.24–0.65 S·m −1 ) even under extreme conditions at −20 °C—virtually unchanged from its performance at room temperature (25 °C). Notably, the strain sensor based on eutectogels exhibits outstanding sensitivity performance both in low-temperature and ambient environments (GF = 2.70 at −20 °C and GF = 2.54 at 25 °C). This is attributed to the gel's ability to maintain its mechanical and electrical properties at low temperatures, demonstrating its potential for application under harsh conditions. Additionally, eutectogels have been successfully applied in pressure sensors and supercapacitors to monitor pressure signals and store energy. Overall, this study has developed a promising strategy for preparing functional, freeze-resistant green composite sensors for engineering applications.

To mitigate the thermal instability of essential oils, we engineered robust colloidosomes via the cross-linking of soy protein isolate nanoparticles (SPI NPs) using poly(hexamethylene diisocyanate) (PHDI) to encapsulate clove essential oil (CEO). Subsequent to a systematic screening of filler loadings, these colloidosomes were incorporated into a gelatin-κ-carrageenan (GK) matrix. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) confirmed that PHDI initiated nucleophilic addition, constructing a rigid shell while facilitating secondary interfacial grafting. This covalent interlocking ensured uniform dispersion and eliminated phase separation defects. In particular, the 40 wt% PHDI treatment yielded complete shell integrity, effectively shielding the CEO from thermal degradation. Accordingly, the optimized GK-CE-40 film featured a densified network structure, translating to superior UV/water vapor barrier properties, high tensile strength (13.41 ± 1.56 MPa), and sustained antioxidant/antibacterial activity (51.28% DPPH scavenging; 20 mm inhibition against E. coli ). Preservation trials on cherry tomatoes demonstrated significant retention of firmness and appearance over 10 days. These results validate interfacial cross-linking as a potent strategy to resolve the stability-dispersibility trade-off in bio-based packaging.

As a globally prevalent cause of disability, lumbar disc herniation has structural disruption of the annulus fibrosus (AF) as its pathological core. To address three critical bottlenecks in AF repair—microenvironmental imbalance (excessive inflammation/oxidative stress), inadequate cellular regeneration (low cell density), and mechanical instability—this study developed an ultrasound-responsive piezoelectric hydrogel scaffold (CPS gel) composed of cerium dioxide, poly-L-lactic acid fibers, and sodium alginate. The core mechanisms include: 1) Immune Reprogramming: Ceria nanoparticles exert dual superoxide dismutase/catalase-mimetic catalytic activity to scavenge reactive oxygen species, inhibit the NF-κB signaling pathway, downregulate IKKα/IκBα phosphorylation, and thereby drive macrophage polarization toward the M2 phenotype; 2) Directed Cellular Regeneration: Ultrasound-activated piezoelectric effects from PLLA fibers facilitate cell migration and proliferation via the ITGβ1/PI3K/AKT/ERK pathway, promoting collagen secretion; 3) Mechanical Reconstruction: The sodium alginate "egg-box" network provides physiologically matched compressive modulus, and in vivo experiments confirm the restoration of intervertebral disc compressive stiffness. Employing a triple synergistic strategy—immunomodulation, cell recruitment, and mechanical restoration—this study proposes a promising solution for structural regeneration of the annulus fibrosus.

Striking a balance between sensitivity and detection range while ensuring stability under extreme temperatures remains a formidable challenge in the design of flexible pressure sensors. To address this issue, we draw inspiration from the multi-gradient architectures of nature and propose a bottom-up self-assembly strategy. By leveraging a meticulously orchestrated multi-step approach that encompasses electrospinning, sequential freezing, and thermal imidization, we successfully fabricate a polyimide nanofiber/carbon nanotube dual-gradient aerogel with a dynamic stiffness transition from flexible to rigid states. Experimental results highlight notable properties of the dual-gradient aerogel, which exhibits an ultralow density (0.023 g cm − 3 ), efficient thermal insulation (28 mW m − 1 K − 1 ), and reliable compressibility and fatigue resistance. Moreover, it establishes a favorable equilibrium between sensitivity (156 MPa − 1 ) and an extensive detection range (223 kPa). Notably, the combination of thermal resilience (−196 °C to 533.30 °C) and mechanical stability enables performance that is comparable to, or in some aspects surpasses, that of conventional flexible sensing materials. This dual-gradient aerogel provides both effective thermal insulation and high-precision physiological monitoring under extreme conditions, offering integrated thermal protection and real-time astronaut health assessment in spacesuits.

In response to the burgeoning challenge of electromagnetic wave pollution, the development of high-performance electromagnetic wave absorbing materials with strong attenuation capability is urgently needed. In this study, a MXene/NiO nanowire hybrid aerogel was constructed via electrostatic self-assembly, leveraging a multi-mechanism synergistic loss strategy to significantly enhance the electromagnetic absorbing performance. The three-dimensional conductive network of the material optimizes impedance matching, facilitating electromagnetic wave penetration into the interior for multiple reflections and scattering, thereby reducing surface reflection. Simultaneously, the highly conductive MXene contributes to substantial conduction loss, while abundant defects (graphitic defects, oxygen-containing groups) and heterogeneous interfaces (MXene-NiO) induce notable dipole and interfacial polarization losses. Furthermore, the nano-heterostructure formed between NiO nanowires and MXene enhances interfacial polarization through charge accumulation at the interfaces. Benefiting from these synergistic loss mechanisms, the optimized aerogel exhibits exceptional electromagnetic wave absorption performance, achieving a minimum reflection loss ( RL min ) of −53 dB at a thickness of 1.6 mm and an effective absorption bandwidth (EAB) of 4 GHz. Our findings propose an innovative materials design doctrine enabling precise multi-scale regulation of electromagnetic wave absorption in aerogels.

Crystalline-amorphous heterointerfaces, enriched with unsaturated coordination sites and tunable electronic structures, hold great potential for accelerating the hydrogen evolution reaction (HER). However, conventional synthesis strategies provide little control over their density and spatial distribution. Here, by tailoring the Fe composition in NiFe x P, we achieve dynamic phase evolution that drives extensive dissolution-redeposition of Fe 2 P domains, producing dense defect-rich, sub-nanometer amorphous NiFeOOH on NiFe x P (NiFeOOH@NiFe x P). This process enables precise regulation of interface density and establishes intimate crystalline-amorphous junctions. Density functional theory calculations reveal that such interfaces synergistically activate a dual-pathway mechanism: amorphous NiFeOOH reduces the water dissociation barrier to 0.834 eV, while crystalline NiFe x P weakens H* binding via d-band modulation, jointly overcoming the kinetic bottleneck. As a result, the activated NiFeOOH@NiFe 0.2 P catalyst exhibits an ultralow overpotential (only 20 mV at 10 mA cm -2 ), a low Tafel slope of 35.86 mV dec -1 , and remarkable durability (20 mA cm -2 for over 60 h). This work highlights interface-density engineering as a powerful route to break the kinetic bottleneck of alkaline HER.

Zirconium-based conversion coatings (ZCCs) are a promising chromium-free alternative for aluminum alloys but are often suffer from weak interfacial bonding with organic topcoats and limited long-term durability. To address these challenges, a silane–zirconium hybrid conversion coating was developed by incorporating KH-560 silane into a ZCC formulation for ADC12 aluminum alloy. The influence of silane concentration on coating microstructure, interfacial chemistry, adhesion and corrosion performance was systematically investigated using SEM, AFM, XPS, and electrochemical techniques, complemented by density functional theory (DFT) calculations. An optimal KH-560 concentration of 20 g/L (ZCC-KH560-20) produced a dense, crack-free, and hydrophobic hybrid film through the formation of a cross-linked Si–O–Si network and covalent Si–O–Zr bonds, leading to enhanced coating compactness and interfacial stability. Consequently, the corrosion current density decreased by two orders of magnitude, while epoxy–substrate adhesion increased nearly fivefold (from 2.61 to 12.32 MPa). Extended electrochemical impedance monitoring revealed that the ZCC-KH560-20–EP system maintained impedance values above 10 8 Ω·cm 2 after 60 days of immersion in 3.5 wt% NaCl solution. The enhanced durability arises from a synergistic mechanism combining a robust physical barrier with active self-passivating. This study provides mechanistic insight and a quantitative strategy for designing sustainable hybrid conversion coatings for aluminum alloys.

Significant challenges have limited the fabrication of complex SiC structures with high strengths for direct ink writing. Therefore, this study developed a novel SiC ink using Al 2 O 3 and Y 2 O 3 as sintering additives to prepare high-strength, complex SiC structures via a combination of direct ink writing and liquid-phase sintering. The effects of Al 2 O 3 + Y 2 O 3 addition on rheological behaviours of the SiC inks and the resultant microstructures and mechanical properties were systematically investigated. The results revealed that a 45.0 vol % SiC ink with 4.1 wt% Al 2 O 3 + Y 2 O 3 exhibited desirable rheological properties, including a low viscosity of 5.73 Pa s at 50 s −1 and shear yield stress of 325.23 Pa for depositing regulated and precise structures. Using this ink, various complex SiC ceramics were successfully fabricated, achieving a maximum densification of 89.5 ± 0.4 %, bending strength of 134.7 ± 8.3 MPa, and Vickers hardness of 15.66 ± 1.50 GPa after sintering at 1950 °C for 1 h. Conversely, the 45.0 vol% SiC ink with 7.4 wt% Al 2 O 3 + Y 2 O 3 caused nozzle blockages and produced irregularly layered structures with defects. This study offers a new method for the direct ink writing of complex, high-strength SiC ceramics, showing significant potential for applications in various fields.

The rational integration of support structures and alloying strategies is crucial for developing highly active and durable catalysts to advance fuel cell technology. This study presents a polyaniline-supported palladium-nickel alloy catalyst (Pd 7 Ni 3 -PANI) with an electronic structure modulated by synergistic metal-support interaction and lattice strain and shows significantly enhanced electrocatalytic performance for ethylene glycol and ethanol oxidation (EGOR/EOR). For EGOR/EOR, the Pd 7 Ni 3 -PANI catalyst shows mass/specific activities (5396/2541 mA mg Pd -1 , 33/15 mA cm −2 ), surpassing those of commercial Pd/C (724/565 mA mg Pd -1 , 12/9 mA cm −2 ). Moreover, Pd 7 Ni 3 -PANI also demonstrates superior CO tolerance and electrochemical stability. These improvements are attributed to the oxyphilic Ni facilitates the generation of hydroxyl (OH – ) to accelerate CO oxidation, while simultaneously optimizing the electronic state of Pd to regulate the adsorption of reaction intermediates. This work provides a new strategy for designing cost-effective and efficient anode electrocatalysts.

Introduction: This study investigated the effects of air frying duration on the texture, color, and flavor characteristics of Andrias davidianus meat slices.Methods: Meat slices were air fried at 180 °C for 0–20 min. Quality attributes and volatile compounds were analyzed using HS-GC-IMS and multivariate statistical analysis.Results: With increasing frying durations, the shear force and a* values significantly increased (P < 0.05), whereas the yield and L* values decreased (P < 0.05), and the b* value peaked at 15 min. A total of 48 volatile compounds, including aldehydes, ketones, esters, acids, alcohols, terpenes, and sulfides. The aldehyde and ketone contents increased with frying durations, whereas the ester and sulfide contents decreased, and the acid contents increased and then decreased. Principal component analysis (PCA) effectively distinguished samples at different frying stages, and orthogonal partial least squares discriminant analysis (OPLS-DA) identified 22 key volatiles with variable importance in projection (VIP) > 1. Relative odor activity value (ROAV) analysis further revealed 15 odor-active compounds (ROAVs = 1), among which 1-octen-3-ol, hexanal, ethyl 2-methylpropanoate, methyl benzoate, and diallyl disulfide were key aromatic substances.Conclusions: Air frying at 180 °C for 10–15 min resulted in more desirable quality and flavor characteristics, providing guidance for the development of ready-to-eat giant salamander meat products.

Achieving high color rendering index (CRI) in white LEDs requires the use of red-emitting phosphors. With the expanding application range of high-power LEDs and laser diodes, the demand for thermal stability of phosphor has become increasingly stringent. In this study, a series of novel red-emitting phosphors Sr 2- x LiAlO 4 : x Sm 3+ ( x = 0.01–0.18) were synthesized by a solid-state reaction. Under 407 nm excitation, this phosphor displays a prominent red emission (608 nm) characterized by the dominant 4 G → 6 H transition of Sm 3+ . The phosphor maintains 98.5% of its luminescence intensity at 200°C compared to room temperature (30°C). This indicates that Sr 1.91 LiAlO 4 : 0.09Sm 3+ phosphor has excellent thermal stability, which is attributed to the high rigidity of its crystal structure. A white LED was fabricated by coating a 365 nm near-UV chip with a blend of phosphors: the red Sr 1.91 LiAlO 4 : 0.09Sm 3+ , a yellow-green (Sr, Ba) 2 SiO 4 : Eu 2+ and a blue BaMgAl 10 O 17 : Eu 2+ phosphors. The device emits white light with a high color rendering index (CRI) of 94.4 and a correlated color temperature (CCT) of 5625 K. The results demonstrate the promising application potential of the Sr 1.91 LiAlO 4 : 0.09Sm 3+ red phosphor in white LED applications.
