Polysaccharide-based adhesives hold promise for wet tissue repair, yet their application is often limited by weak interfacial bonding and insufficient cohesive strength in hydrated environments. Here, we report a root-inspired multilevel wet bioadhesive enabled by helical-cavity-preserving starch engineering for corneal repair. Potato starch was sequentially succinylated and methacrylated under aqueous conditions to obtain methacrylate succinate diesterified starch (StaCMA), which retained the ability to form helical-cavity structures while introducing photocrosslinkable groups. When integrated with methacrylated gelatin, StaCMA formed a transparent hydrogel network that mimicked root-like anchoring through tissue-interpenetrating covalent fixation, branched-chain stress dissipation and helical-cavity-mediated polymer confinement. The optimized adhesive exhibited strong wet adhesion on human cornea, achieving a shear adhesion strength of 166 kPa and a burst pressure of 1286 mmHg, while maintaining visible-light transmittance above 90%. Iodine displacement, FTIR, NOESY, helix-denaturation controls and molecular dynamics simulations supported that starch helical cavities confined GelMA segments and promoted molecular association, thereby reinforcing both adhesion and cohesion. In ex vivo and rabbit corneal injury models, the adhesive enabled sutureless sealing of linear and irregular penetrating wounds and supported organized corneal regeneration with reduced fibrotic remodeling. This study establishes helical-cavity-preserving starch as an active carbohydrate-polymer motif for root-inspired wet bioadhesive design.

The biodegradation of polycyclic aromatic hydrocarbons (PAHs) involves complex metabolic interactions among multiple degradation pathways. However, how interactions among different pathways influence the overall degradation efficiency remains poorly understood. In this study, Pseudoxanthomonas sp. G3, an efficient degrader of phenanthrene (PHE) and pyrene (PYR), was used to investigate pathway interactions under mixed-PAH conditions. Genomic and metabolomic analyses revealed that strain G3 degrades PHE and PYR through three pathways: the phthalate pathway (with phthalic acid as the dead-end product), a shared catechol degradation pathway, and the benzoate degradation pathway. Notably, PYR induced the benzoate degradation pathway, representing a previously unreported metabolism of PYR by bacteria. Integrated analyses revealed that PHE inhibits PYR degradation via dual mechanisms. Specifically, PHE preferentially utilizes the PYR-induced benzoate degradation pathway, thereby diverting metabolic flux and impeding PYR degradation. Moreover, the benzoate degradation pathway further inhibits the catechol degradation pathway, intensifying suppression of PYR degradation. These findings elucidate mechanistic insights into the interactions among the biodegradation pathways under mixed-PAH stress and provide a theoretical basis for targeted improvement of the efficiency and predictability of mixed-PAH degradation.

The hydrogen isotope composition (δ2H) of fatty acids is a promising proxy for tracing cellular metabolic pathways and rates and for cancer diagnosis. However, conventional methods based on gas chromatography-isotope ratio mass spectrometry (GC-IRMS) could only measure molecular-average isotopic values, obscuring position-specific variations that could be more sensitive to metabolisms. To perform position-specific hydrogen isotope analysis (PSIA) of fatty acids, we used a GC-Orbitrap (Exploris 240 GC) to acquire isotopologue ratios of two fragment ions, 12C42H1H616O2+/12C41H716O2+ and 12C52H1H816O2+/12C51H916O2+, in methyl esters of palmitic acids. To allow longer acquisition of isotopologue ratios of each sample analysis, we added a custom peak-broadening system composed of two four-port switch-valves and a passivated sample loop. This peak broadener is installed between the chromatographic column and the MS transfer line and enables precise capture and release control of target compounds, allowing 12 min stable release of the eluate. Each analysis consumes only 7.6 nmol of sample and reaches experimental precision of 5.4‰ for C4H7O2+ and 8.8‰ for C5H9O2+ (1 standard deviation of 5 analyses). Using palmitic acid labeled with one 2H atom in the 12th position, we found negligible hydrogen scrambling. Also, label-addition experiments allow us to compare whole-molecule δ2H measurements using GC-IRMS with those from GC-Orbitrap, and we obtained a near-precise match with a correlation slope of 1.044 across a composition range of −223–418‰. We establish a method for position-specific δ2H measurement of fatty acids on nanomolar sample quantities, opening possibilities for new geological, environmental, and medical applications.

Environmentally benign water-based lubricants are attracting increasing attention as alternatives to conventional oil-based lubricants that may cause environmental pollution. Herein, three protic poly(ionic liquid)s (PPILs) are synthesized by combining a copolymeric cation with carboxylate anions of different alkyl chain lengths. The PPILs are employed as additives in aqueous lubricants, and their viscosity-enhancing capability and tribological performance are systematically evaluated. Quartz crystal microbalance (QCM), electrical contact resistance (ECR), X-ray photoelectron spectroscopy (XPS), and time-of-flight secondary ion mass spectrometry (TOF-SIMS) are used to elucidate the lubrication mechanism. The results demonstrate that PPILs significantly improve the viscosity, corrosion resistance, and tribological properties of water-based lubricants. Notably, the kinematic viscosity of a 6% PPD-Oa aqueous solution increases by two orders of magnitude compared with deionized water, while the corresponding wear volume and coefficient of friction are reduced by approximately 77% and 70%, respectively. Mechanistic investigations indicate that interfacial adsorption and friction-induced chemical processes jointly generate a protective layer at the sliding interface, thereby imparting excellent lubricity and load-bearing capability to the lubricant. Moreover, the three sulfur-free and halogen-free PPILs represent environmentally benign additives with strong potential for application in metalworking fluids and hydraulic systems.

A crystal-interface-engineering guided imperfect-orientation mechanism is developed to regulate the fabrication of cactus-mimetic ZnO nanohybrids. • The as-prepared cactus-mimetic nanohybrids exhibit topography-governed ultrafast mechanical bactericidal activity. Mechanical bactericidal strategies based on biomimetic micro/nanostructures have emerged as a green and sustainable disinfection approach, owing to their low tendency to induce microbial mutation and resistance, as well as the absence of chemical-related side effects and toxic byproducts. However, current mechanical bactericidal surfaces predominantly rely on single nanostructures (e.g., nanopillars, nanosheets, or nanocones), whose bactericidal efficacy is often constrained by the inherent limitations of a single action mode. Inspired by the hierarchical structure of cacti, which integrates both blade-like sheets and sharp spines, we herein report a cactus-mimetic ZnO nanohybrid featuring nanosheets decorated with epitaxially grown nanoneedles, fabricated via a crystal-interface-engineering strategy under ambient conditions. The growth mechanism involves dislocations generated by imperfect oriented attachment between crystals, which serve as secondary nucleation sites. An ultrafast mechanical bactericidal activity evaluation platform was designed for the subsequent mechanical bactericidal tests. This unique hierarchical architecture enables a synergistically enhanced mechanical bactericidal mechanism, which mainly involves concurrent actions of stress-stretching, edge-cutting and needle-piercing at multi-scaled contact interfaces, as well as their cooperative effects. The synergistic integration of these mechanical actions enables ultrafast bacterial inactivation, achieving a 99.99% bactericidal efficiency against both Escherichia coli and Staphylococcus aureus (10 6 CFU/mL, 300 μL) within just 1 min of contact, demonstrating a significantly outperforming pristine ZnO nanosheets. This work provides a new design paradigm for high-performance mechanical bactericidal materials by harnessing synergistic multi-mechanism actions, offering a rapid and sustainable solution for water disinfection and infection control applications.

Liquid-metal-assisted annealing enables in situ growth of vertically aligned graphene on diamond. • Structural evolution from discontinuous graphene domains to continuous shells forms interconnected sp 2 networks and heterointerfaces. • Optimized G@D-2 exhibits RL min of −42.89 dB, EAB of 4.43 GHz, and TC of 25.99 W m −1 K −1 . Highly integrated and miniaturized electronic systems impose concurrent demands on efficient thermal management and electromagnetic interference suppression. Diamond possesses ultrahigh thermal conductivity, yet its poor impedance matching and limited loss mechanisms result in insufficient electromagnetic wave absorption. Here, we report a structural regulation strategy based on complementary coupling of carbon allotropes to address this issue. A vertically aligned graphene shell is in-situ constructed on artificial diamond particles via liquid-metal-assisted annealing, forming a core-shell graphene@diamond (G@D) heterostructure with tunable interfacial hybridization. The structural evolution from discontinuous graphene domains to a continuous shell establishes a continuous sp 2 conductive network and heterogeneous interfaces. As a result, both impedance matching and dielectric loss are optimized simultaneously. The optimized material exhibits a minimum reflection loss of −42.89 dB and an effective absorption bandwidth of 4.43 GHz. Mechanistically, the excellent performance is mainly attributed to the synergistic effect of conductive loss, interface polarization and multiple scattering, which is determined by the evolution of interface continuity and the modulation of sp 2 /sp 3 hybridization ratio. Meanwhile, the formation of continuous interfacial thermal pathways effectively suppresses phonon scattering, leading to a high thermal conductivity of 25.99 W m −1 K −1 in the polymer matrix (7.5 times that of the physically mixed system). This work provides a general paradigm for integrating electromagnetic attenuation and thermal transport within a single filler system, offering new opportunities for multifunctional materials in high-power electronics and advanced packaging.

A monolithic mesh evaporator with dual-mode heating was developed for all-weather desalination. • CuS nanosheets and CNTs achieve complementary broad-spectrum absorption (∼92%). • The hierarchical porous structure reduces evaporation enthalpy and accelerates vapor escape. • Solar-electric collaboration achieves 24 h continuous freshwater production. Solar-driven interfacial water evaporation is attracting increasing attention as a promising environmentally-friendly solution to freshwater scarcity. However, achieving efficient and uninterrupted solar-driven seawater desalination remains challenging due to intermittent sunlight and salt fouling. Herein, a monolithic integrated evaporator of a mesh composite (CNTs-CuS-CuO/Cu) was fabricated for all-weather seawater desalination via dual-mode (solar-thermal and Joule-heating) interfacial evaporation. A hierarchical microporous structure was obtained by combining CuS nanosheets grown in situ with sprayed carbon nanotubes (CNTs). This design offers three key advantages: (1) CuS enhances near-infrared absorption, complementing the visible-light absorption of CNTs for efficient solar capture (an average light absorbance of approximately 92%). (2) The porous network enlarges the evaporation area, facilitates rapid vapor escape, and provides ample water transport channels, effectively reducing the water evaporation enthalpy. (3) The conductive copper mesh enables low-voltage Joule-heating, allowing for continuous fresh water production at night or under weak sunlight. This “solar-thermal and Joule-heating” synergy ensures operability, overcoming weather dependency. The obtained results demonstrated that the CNTs-CuS-CuO/Cu mesh composite can produce a daily freshwater yield exceeding Under natural sunlight, the CNTs-CuS-CuO/Cu mesh composite achieved a high daily freshwater output of more than 32.7 kg·day ⁻1 under natural sunlight. The total ion concentration of the fresh water is as low as 19 ppm, which is well below the World Health Organization (WHO) drinking water threshold of 500 ppm. This work presents a promising strategy for designing high-performance, anti-fouling, and all-weather evaporators for practical seawater desalination.

A novel class of orange-red emitting Lu 2 SrAl 4 SiO 12 : x Sm 3+ phosphors was synthesized via a high-temperature solid-state reaction. Rietveld refinement confirmed that Sm3+ dopants successfully substitute Lu 3+ sites within the cubic garnet matrix. Under 405 nm near-ultraviolet excitation, the phosphors exhibit intense orange-red emissions, with the dominant peak at 618 nm originating from the 4 G 5/2 → 6 H 7/2 transition. Investigations reveal that the maximum luminescence output is achieved at a doping level of x = 0.03. Beyond this point, the concentration quenching process is dominated by dipole-dipole interactions, with the critical energy transfer distance calculated to be 18.88 Å. The optimized phosphor ( x = 0.03) exhibits an internal quantum efficiency of 16.7% and a fluorescence lifetime of 2.16 ms. It demonstrates robust thermal stability, retaining 68% of its initial intensity at 423 K. The activation energy governing this thermal quenching process is determined to be 0.187 eV. All single-doped samples exhibit ultra-high color purity exceeding 98.4%. By blending the Lu 2 SrAl 4 SiO 12 :0.03Sm 3+ phosphor with commercial blue/green phosphors on a 405 nm n-UV chip, a high-performance white light-emitting diodes device were fabricated, achieving a warm correlated color temperature of 4318 K and a high color rendering index of 84.53. Furthermore, its successful application as security inks across diverse substrates confirms Lu 2 SrAl 4 SiO 12 :0.03Sm 3+ as a highly promising dual-functional material for advanced solid-state lighting and optical anti-counterfeiting.

A KGM/CMC/PVA film loaded with a hydroxypropy-β-cyclodextrin/hesperetin (HP-β-CD/HES) inclusion complex was developed for strawberry preservation. The inclusion complex showed an encapsulation efficiency of 70.41 ± 4.01%. Loading the inclusion complex enhanced the barrier and bioactive properties of the films. At the better loading level (KCP-HH3, 1.5%), the film provided nearly complete UV shielding at 200–350 nm and showed a transmittance of approximately 21% at 800 nm. Relative to KCP, KCP-HH3 exhibited lower water vapor permeability (0.69 ± 0.06 g·mm/(m2·h·kPa)) and oxygen permeability (0.066 ± 0.006 g·mm/(m2·h·kPa)). The cumulative HES release from KCP-HH3 reached 82.43 ± 2.19% after 7 days at 98% relative humidity. KCP-HH3 scavenged 78.19 ± 3.71% of DPPH radicals and 88.89 ± 4.30% of ABTS radicals. It also inhibited Escherichia coli (91.18 ± 2.99%), Staphylococcus aureus (79.21 ± 3.45%), and Aspergillus niger (92.85 ± 2.75%). This highest-loading formulation delivered the best overall strawberry-preservation performance. After 12 days of storage, strawberries packaged with KCP-HH3 showed higher firmness (0.89 ± 0.04 N) and total soluble solids (7.96 ± 0.21%), as well as lower weight loss (14.30 ± 0.40%), than the polyethylene control, which showed a firmness of 0.42 ± 0.05 N, total soluble solids of 6.22 ± 0.20%, and weight loss of 16.36 ± 0.66%. These results support the potential of HP-β-CD/HES-loaded KCP films as biodegradable active packaging for fruit preservation.

Iron powder cores are widely used in cost-sensitive low- to medium-frequency applications because of their high saturation magnetisation, low cost and favourable formability. However, the low electrical resistivity of iron powders favours continuous conductive pathways between adjacent particles, leading to high-frequency eddy-current loss and heat accumulation. To combine electrical insulation, interfacial stability, magnetic-property retention and thermal diffusion in a single coating, a synergistic insulation/thermal-conduction coating based on thiol-functionalised boron nitride was designed for iron-based magnetic powder cores. Hexagonal boron nitride was surface-modified through ultrasonic activation followed by grafting with a mercaptosilane coupling agent, forming covalent linkages on the boron nitride surface. The resulting functionalised nanosheets were deposited onto water-atomised iron powders through interfacial interactions between nitrogen- and sulfur-containing functional groups and the iron surface. A coating content of 5 wt.% produced a relatively continuous and uniform interfacial layer with limited agglomeration, enabling the magnetic powder cores to combine interparticle insulation, loss reduction, magnetic-property retention and thermal transport. The optimised core exhibited a volume resistivity of 58.7 Ω·m and a total core loss of 81.2 kW/m3at 10 mT and 100 kHz, corresponding to a 20.8% reduction relative to the pure iron core. The sample retained a saturation magnetisation of 201.4 emu/g and an effective permeability of 67.5 at 100 kHz, while achieving a thermal conductivity of 55.2 W/(m·K) and a thermal impedance of 0.215 K·m2/W. Loss-separation analysis indicates that the continuous insulating layer restricts interparticle induced-current pathways and suppresses high-frequency eddy-current loss, while the two-dimensional boron nitride framework promotes internal thermal diffusion.

TheHoupoea officinalisflower (HOF) represents an underutilized sustainable bio-resource. This study systematically evaluated its potential using an ethanol-based green extraction process optimized by Response Surface Methodology, with the optimal conditions consisting of approximately 50% ethanol, a solvent-to-solid ratio of 54 mL/g, and an extraction time of 31 min. Chemical profiling across four developmental stages—S1 (Bud), S2 (Bud swelling), S3 (Initial flowering), and S4 (Full bloom)—suggested magnolol and honokiol as the major phenolic compounds, showing a trend of decline during early development followed by an increase at the S4 stage. A significant positive correlation was observed between total phenolic content and antioxidant activity, and the S1 stage extract displayed the strongest antioxidant capacity in multiplein vitroassays. Network pharmacology analysis predicted oxidative stress-related targets and pathways, with TP53, AKT1, IL6, BCL2, and CASP3 recognized as key hub genes. Molecular docking further predicted favorable binding interactions between major HOF phenolics and these target proteins. Collectively, these findings reveal the multi-target antioxidant potential of HOF and provide evidence supporting its potential role in antioxidant-related traditional applications based on predicted mechanisms. Moreover, HOF, particularly at the S1 developmental stage, shows promise as a sustainable source of natural antioxidants and functional ingredients, promoting the high-value utilization of agricultural by-products.

Background: Myocardial ischemia-reperfusion (MIR) injury remains the leading cause of adverse outcomes after myocardial infarction, and its prevention remains a major therapeutic challenge. Methods: The GSE160516 and GSE61592 datasets from the Gene Expression Omnibus database were analyzed to screen MIR-related differentially expressed genes. To simulate clinical MIR injury, male C57BL/6 mice were subjected to ligation of the left anterior descending coronary artery for 30 minutes, followed by reperfusion for 24 hours. Results: In this study, the protein-protein interaction network was generated based on the 34 common upregulated genes, and among them, 11 genes were identified as hub genes, including solute carrier family 11 member 1 ( Slc11a1 ), a gene associated with immune response. Herein, the upregulation of myocardial Slc11a1 was validated in mice with MIR injury. Mice subjected to MIR had improved cardiac function when Slc11a1 was knocked down via myocardial injection of Slc11a1 small interfering RNA (siRNA): the infarcted areas reduced from 38.43±4.13% to 22.18±3.45%; CK-MB levels decreased from 12.01±3.11 to 5.84±1.24. Slc11a1 silencing also reduced infiltration of F4/80 macrophages, deactivated the p65 proinflammatory pathway, and decreased the generation of IL-6 and TNF-α. Myocardial oxidative stress induced by IR challenge was attenuated in mice receiving Slc11a1 siRNA. Conclusion: Our study demonstrates that the abnormal elevation of Slc11a1 contributes to IR-related myocardial injury.
