Inspired by the rooting of seeds, dual-functionalized silica nanoparticles (FM x SiO 2 ) with both perfluorooctyl (F) and methacrylate (M) groups were prepared and used to develop a UV-cured polyurethane acrylate (PUA) hybrid coating having a unique balance of high hardness, excellent transparency, and superior anti-smudge performance. The FM x SiO 2 nanoparticles with various F/M ratios (x) were synthesized via a controlled sol-gel process and co-modified by changing the volume ratios of 1H,1H,2H,2H-perfluorodecyltrimethoxysilane (FAS-17) to 3-methacryloxypropyltrimethoxysilane (MPTS). The methacrylate groups (from MPTS) enabled covalent crosslinking with the polymer matrix during photopolymerization, while the perfluorodecyl groups (from FAS-17) facilitated nanoparticle migration to the surface, forming a low surface energy layer. The optimized hybrid coating with 5 wt% FM 5 SiO 2 exhibited outstanding mechanical and surface properties, including a pencil hardness of 9H, a Young's modulus of 42.7 GPa, and visible light transmittance of up to 97%. Furthermore, the surface energy was significantly reduced to 25.8 mJ·m −2 , endowing the coating with excellent water and oil repellency, scratch resistance, and self-cleaning behavior. These excellent physical properties were attributed to FM x SiO 2 NPs with efficient surface migration and uniform dispersion having strong interfacial bonding with PUA. This study provides a synergistic design strategy that combines nanoscale reinforcement and surface-energy regulation to fabricate transparent, mechanically robust, and self-cleaning UV-curable coatings.

Lightweight materials relying on multiple ordered architected systems that emerge as next-generation shock-absorbing and high-impact applications with exclusive mechanical performances, but integrating and precisely fabricating them effectively into a single enclosed system remains a challenge. Here, a foam-integrated lattice design strategy is introduced, combining grid-stiffening guided topology optimisation to design metamaterials and 3D-printed elastomeric foams to fabricate designed complex structures. Spatially equivalent grid-assisted hierarchical architecture lattices were generated and validated by experimental and numerical simulations. A dual curable mechanism is utilised via vat photopolymerization and thermal foaming process by formulating dynamically curable polyurethane resin with thermally expandable microspheres. 3D printed structure exhibits a 1.7-fold expansion with a reduced density of 215 kg/m³ with high resolution and accuracy. Upon these features, lattice (star-diamond interwoven) delivered outstanding performance, achieving 600% stiffness and 1100% strength in non-foamed condition, and reaching 0.84J with an energy absorption efficiency of 48% (240% higher than non-foam) with foam integration, compared to the Kelvin lattice. Synergistical outcome revealing that closed cell foam formation on hierarchical structures with elastomeric crosslink functionality is well-bounded. The integrated design confirms further superior cushioning and energy absorption in shoe sole prototypes, establishing a scalable framework for precision-tuned architected foamed lattices in impact-mitigating applications.

The development and functional utilization of light-colored lignin are largely hindered by uncontrolled condensation reactions during extraction, which reduces lignin reactivity and compromises its functional performance. Herein, a formic acid/L-Cysteine (FA/L-Cys) pretreatment system was developed to fractionate functional light-colored lignin from bamboo. Under mild conditions (100 ° C, 1 h), this system achieved 95.3% delignification and 71.3% lignin recovery, affording pale beige lignin with a lightness value of 80.9. 2D-HSQC NMR analysis revealed that L-Cys suppressed lignin condensation by nucleophilically trapping reactive intermediates. When incorporated into a sun protection factor (SPF) 15 sunscreen formulation at 5 wt %, the optimized lignin (L-Cys-0.3) increased the SPF to 71.7. Moreover, L-Cys-0.3-derived lignin nanoparticles efficiently stabilized Pickering emulsions and exhibited a 12-fold enhancement in UV absorption capacity compared with their LNPs aqueous dispersion counterparts. This work highlights condensation-controlled fractionation as an effective strategy for producing light-colored lignin with potential applications in sustainable sunscreens and functional Pickering emulsion systems.

HP-γ-CD-grafted zwitterionic copolymer enables PT-μSPE of FQs. • Complementary γ-CD and MPC sites provide recognition and matrix tolerance. • DFT calculations support complementary hydrogen-bonding and electrostatic interactions. • PT-μSPE-HPLC-UV enables FQ determination in milk and honey. The trace determination of fluoroquinolone antibiotics (FQs) in animal-derived foods requires effective sample pretreatment to minimize matrix interference and improve analytical sensitivity. Herein, a pipette-tip micro solid-phase extraction method coupled with high-performance liquid chromatography and ultraviolet detection (PT-μSPE-HPLC-UV) was developed for the determination of FQs in food samples. A porous zwitterionic cyclodextrin-based copolymer was synthesized as the PT-μSPE sorbent. The copolymer integrates hydroxypropyl-γ-cyclodextrin (HP-γ-CD) cavities with zwitterionic phosphorylcholine groups, combining host-guest recognition, hydrogen bonding, electrostatic interactions, and antifouling hydration to improve analyte enrichment and matrix tolerance. Density functional theory (DFT) calculations suggested complementary recognition in the hybrid system, which exhibited generally shorter hydrogen-bond distances than those calculated for the zwitterionic monomer-only models and electrostatic potential extrema of greater magnitude than those of γ-CD alone. Under the optimized conditions, the method exhibited good linearity over the range of 1.0 to 500 μg L⁻¹, limits of detection of 0.07 and 0.24 μg L⁻¹, and limits of quantification of 0.23 and 0.72 μg L⁻¹ for lomefloxacin and gatifloxacin, respectively. Recoveries in spiked milk and honey ranged from 74.8% to 110.3%, and norfloxacin and enrofloxacin were also effectively enriched. The proposed miniaturized method provides a simple, economical, and practical approach for FQs enrichment and screening in complex food matrices.

Anthocyanin-based pH-responsive indicators are promising for food freshness monitoring, but UV exposure during transportation and retail display causes chromophore degradation and fading. Herein, core–shell sodium alginate/cinnamaldehyde/zein/anthocyanin nanoparticles (SCZC) were fabricated via a multiscale protection strategy. Anthocyanins were confined in a hydrophobic zein core through hydrophobic and π–π interactions, while cinnamaldehyde-assisted interfacial densification and a sodium alginate shell provided diffusion barriers against external stresses. After incorporation into a carboxymethyl cellulose (CMC) matrix, the CMC film containing 0.4 g SCZC nanoparticles (C/SCZC-0.4) exhibited improved UV and visible-light stability, with ΔEab values of only 5.21 after 4 h of UV irradiation and 5.22 after 8 days of visible-light exposure. Compared with the free-anthocyanin CMC film (C/C), C/SCZC-0.4 reduced anthocyanin migration in water from 84.34% to 35.65%, while improving oxygen barrier performance and tensile strength to 2.32 cm 3 ·μm·m −2 ·day −1 ·kPa −1 and 30.0 MPa. The label retained pH/ammonia responsiveness and visually distinguished seafood freshness. Download: Download high-res image (208KB) Download: Download full-size image

Engineering bioresponsive materials for treating oxidative stress-induced degeneration remains a major challenge in intervertebral disc repair. We developed a UV-crosslinked injectable hydrogel composed of oxidized hyaluronic acid (OHA), gelatin, and polyethylene glycol diacrylate (PEGDA), co-loaded with quercetin and greigite nanozymes (G-NZ), termed OGPQ/G-NZ. This hydrogel exhibits robust structural integrity, shear resistance, and pH/reactive oxygen species (ROS)-responsive release of quercetin. G-NZ provides multi-enzyme–mimetic antioxidant activity, including superoxide dismutase, catalase, and glutathione peroxidase–like functions, along with antibacterial protection. In vitro, the hydrogel maintains nucleus pulposus cell (NPC) viability under oxidative conditions, reduces ROS accumulation, and promotes extracellular matrix (ECM) protein synthesis. In vivo application in a rat intervertebral disc degeneration (IVDD) model significantly preserved disc height, structure, and ECM integrity. RNA-seq and network pharmacology analysis identified PUM1/2-mediated degradation of E2F3 as a key regulatory pathway. Quercetin inhibits PUM1/2 expression, thereby stabilizing E2F3 mRNA and suppressing NPC senescence. Moreover, in vitro assays and CellChat-based single-cell analysis demonstrated that OGPQ/G-NZ modulates inflammatory macrophage polarization and enhances M2–NPC reparative signaling. These results highlight the hydrogel's engineered antioxidant and transcriptome-modulating properties as a promising platform for oxidative stress-responsive IVDD treatment.

Advancements in wearable electronics have driven demand for flexible, self-powered UV photodetectors, yet the efficient separation and transport of carriers remain critical challenges to realizing their full potential. This study constructs a high-performance flexible self-powered UV detector based on an electrochemically doped Bi-ZnO nanoflowers/PEDOT-CH 2 OH p-n heterojunction, further modified with a Co(IO 3 ) 2 layer. Bi 3+ doping introduces oxygen vacancies to enhance carrier separation, synergizing with the built-in electric field within the heterojunction. The spontaneous polarization of Co(IO 3 ) 2 enhances this electric field, optimizing band alignment and suppressing recombination, while hydroxyl groups in PEDOT-CH 2 OH stabilize the oxygen vacancies. The piezoelectric response of ZnO is not prominent in this device, as its modulating effect is overshadowed by the dominant charge separation mechanism based on doping and interfacial polarization. Through synergistic bandgap engineering, defect control, and interface modification, the optimized device achieves a responsivity of 2.05 mA/W, a specific detection rate of 3.25 × 10 10 Jones, and an ultrafast response time of 54 ms under 365 nm UV illumination. The detector exhibits exceptional flexibility, stability, and selectivity, maintaining high performance through 2500 bending cycles, indicating significant potential for application in flexible, wearable UV sensing.

Achieving precise customization and structural regulation of sub-Ångström pores of Carbon molecular sieve membranes (CMSMs) remains challenging. In this study, CMSMs with ultra-high H 2 /CH 4 separation performance were developed by a UV induced super-crosslinking network polyimide precursor, which was formed by click reaction through an imide intermediate that contains C≡CH and the SH as functional end groups. The as-formed polyimide contains C═C─S in each repeat unit of the polyimide which can be crosslinked using UV light via the [2+2] reaction and form molecular “stitches” with a super-crosslinking network. The cross-linking node density can be easily adjusted by the UV irradiation time (0–30 min). During pyrolysis, the dimensions of the connecting interior pore necks for sub-Ångström pores can be fine-tuned (4.0±0.3 Å), promoting the formation of a higher concentrated (4%–8%) sub-4 Å pores. The optimized CMS-30 membrane demonstrates outstanding gas separation performance, with H 2 permeability of 2930 Barrer and remarkable selectivity for H 2 /CH 4 (4651), surpassing the Robeson upper bounds and outperforming most reported CMSMs. This photo-induced super-crosslinking network precursor method provides a versatile strategy for high-performance CMSM by sub-nanometer precision engineering of CMSMs.

Stable physical integration of TiO 2 NPs into the hydrogel network. • Dynamic mechanical properties and pronounced self‑healing capability. • Excellent biocompatibility, UV‑shielding, and anti‑melanogenic activity. • 98.5% wound closure in a full‑thickness mouse model within 14 days. Excessive UV exposure impedes wound healing by damaging fibroblasts and epithelial cells and stimulates melanocytes to overproduce melanin, leading to post-healing hyperpigmentation. To address this challenge, a dynamic dual-network composite hydrogel was developed via Schiff-base crosslinking between aldehyde sodium alginate (ASA) and carboxymethyl chitosan (CMCS), with titanium dioxide nanoparticles (TiO 2 NPs) incorporated through electrostatic interactions. Based on the dynamic Schiff base chemistry, HAC-TiO 2 - Y hydrogels have good self-healing properties. The incorporation of TiO 2 nanoparticles increases network rigidity and physical crosslinking density. The resulting HAC-TiO 2 - Y hydrogels exhibited excellent biocompatibility, supporting > 85% viability of L929 fibroblasts. It also displayed outstanding UV-blocking capability. Notably, the HAC-TiO 2 -2.5 hydrogel showed concentration-dependent anti-melanogenic activity in B16F10 melanoma cells, reducing intracellular melanin content to 74.2% compared to the control. In a full-thickness mouse wound model, the HAC-TiO 2 -2.5 hydrogel achieved 98.5% wound closure within 14 days, significantly outperforming the TiO 2 -free control. By integrating UV protection with wound healing promotion, this multifunctional hydrogel presents a promising strategy for advanced wound management under UV-exposed conditions.

Ferrofluids represent a class of functional materials that combine the flow characteristics of liquids with the magnetic responsiveness of solid magnetic substances. In this study, a novel low-viscosity hydrophobic deep eutectic solvent (HDES) based ferrofluid for vortex-assisted liquid-liquid microextraction (HDES-FF-VA-LLME) technique was proposed for simultaneous extraction of UV filters and parabens from environmental water samples. The ferrofluid was composed of poly(dopamine) modified magnetic nanoparticles and fatty acid based low-viscosity HDESs. The key experimental factors influencing the extraction performance were first screened using a Plackett-Burman design and subsequently optimized through a central composite design. Under the optimized experimental conditions, the method provided limits of detection ranging from 0.05 to 0.25 μg L-1 and limits of quantification between 0.2 and 1.0 μg L-1. The intra-day (n = 5) and inter-day (n = 5) relative standard deviations were both below 3.3%, while enrichment factors varied from 22 to 29. Following the extraction process, the ferrofluid phase could be rapidly isolated by applying an external magnetic field, which eliminates the need for conventional phase-separation procedures and significantly reduces separation time. The extraction mechanism was further investigated using density functional theory calculations. Coupled with high-performance liquid chromatography equipped with a ultraviolet detector, the proposed method was successfully applied to the simultaneous determination of UV filters and parabens in environmental water samples, achieving recoveries in the range of 94.4-107.7%. Overall, the developed approach provides a rapid, straightforward, cost-effective, and environmentally friendly microextraction strategy, showing promising potential for applications in environmental monitoring.

Photooxidation and microbial contamination are two major factors responsible for postharvest deterioration of fresh fruits, and active packaging offers an effective strategy for shelf-life extension. In this work, multifunctional and eco-friendly nanocomposite films were fabricated from polyvinyl alcohol/gelatin (PVA/GEL) incorporated with branched polyethyleneimine (PEI)-grafted carbon dots (CDs) and citral Pickering emulsions (CIT-PE) stabilized by β-cyclodextrin (β-CD) particles. Fourier-transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) analysis suggested physical interactions between the PVA/GEL matrix and the incorporated active components. The incorporation of CIT-PE and CDs significantly enhanced the UV-shielding, antibacterial, and antioxidant properties of the films. In particular, the PG/E8/C0.8 film exhibited complete UV-blocking ability in the UV region (200–400 nm), strong antibacterial activity against E. coli (18.05 ± 0.20 mm) and S. aureus (55.54 ± 0.87 mm), and high DPPH radical scavenging activity (84.49 ± 3.47%). In cherry tomato preservation experiments, the PG/E8/C0.8 film effectively delayed quality deterioration, maintaining a vivid appearance, lower weight loss (4.24%), and better retention of total soluble solids and titratable acidity after 16 days of storage compared with the control group. Overall, this work provides a feasible strategy for developing multifunctional active packaging materials for postharvest food preservation.
