The integration of multifunctional protective materials capable of simultaneous defense against ultraviolet (UV) radiation, O 3 , and reactive oxygen species (ROS) remains a challenge in interfacial materials science, primarily due to difficulties in constructing stable and catalytically efficient interfaces on flexible substrates. Herein, we report a cellulose-guided interfacial engineering strategy for the in-situ growth of copper-based metal-organic framework (Cu-MOF) nanozymes on nylon/spandex fabric. The key to this strategy lies in the pre-coordination of Cu 2 + with the hydroxyl groups of cellulose, which molecularly guides the ordered crystallization of Cu-MOFs within a regenerated cellulose network at the fiber interface, yielding a nanosheet structure with enhanced density and accessibility of catalytic sites. The resulting cellulose-MOF hybrid is firmly anchored to the fabric through a synergistic dual mechanism: physical entrapment within the regenerated porous cellulose network provides structural integrity, while chemical coordination between Cu 2+ and cellulose hydroxyls directs oriented growth and reinforces interfacial adhesion. This precisely engineered interface enables exceptional cascade antioxidant activity (mimicking superoxide dismutase and catalase), high UV protection (UPF > 100), and rapid ozone decomposition (first-order kinetic constant k > 0.478 min −1 ). The material also demonstrates robust interfacial adhesion, ensuring mechanical durability, breathability, and wash durability (>30 cycles). Biocompatibility was confirmed by skin irritation tests. This work highlights the critical role of biomass-templated interfacial microstructure in regulating catalytic performance and provides a green, scalable paradigm for designing advanced functional interfaces for environmental and biomedical protection.

Specific kinetic parameters were determined for each enrofloxacin species (ENR + , ENR 0 , ENR – ) in UV/chlorine treatment. • A pH-independent kinetic modelling method was proposed to decouple the pH-dependent complexity of ENR degradation. • The specific direct photolysis rate constants were calculated to be (1.51–15.09) × 10 –3 cm 2 Ein –1 for each ENR species. • The specific second-order rate constants of ENR towards reactive free radicals were calculated to be (1.11–41.5) × 10 9 L mol –1 s –1 for each ENR species. • ClO • was identified as the dominant reactive species, contributing to over 90% of ENR removal collectively with direct photolysis. The UV/chlorine process has demonstrated superior efficacy in micropollutant degradation. However, the strong pH dependence of second-order rate constants between contaminants and reactive species poses a fundamental challenge to the accuracy and generalizability of kinetic models. In this study, a comprehensive kinetic investigation was conducted on the degradation of enrofloxacin (ENR) by UV/chlorine across its three ionic speciation states (ENR + , ENR 0 , and ENR – ). Key mechanistic insights were obtained through systematic differentiation of degradation pathways, including direct UV photolysis, oxidation by free chlorine, HO • and reactive chlorine species. The specific photolysis rate constants were calculated to be 1.51 × 10 –3 , 15.09 × 10 –3 , and 9.57 × 10 –3 cm 2 Ein –1 for ENR + , ENR 0 , and ENR – , respectively. The specific second-order rate constants for the reaction toward ClO • for ENR + , ENR 0 , and ENR – were calculated to be 5.46 × 10 9 , 1.11 × 10 9 and 4.66 × 10 9 L mol –1 s –1 , respectively. Based on species-specific kinetic parameters, a pH-independent kinetic model for ENR degradation by UV/chlorine were construct, enabling reliable prediction of degradation kinetics at any pH within the selected range. This model provides a robust framework for predicting and optimizing treatment performance, thereby offering critical guidance for the design and engineering application of UV/chlorine processes.

Recombinant humanized type III collagen was prepared as a bioactive macromolecule. • rS-Col III promoted fibroblast adhesion, proliferation, migration, and repair signaling. • rS-Col III alleviated UV-induced oxidative stress in cellular and zebrafish models. • Topical rS-Col III accelerated skin barrier recovery and collagen remodeling in mice. • Recombinant type III collagen shows promise for skin repair and regenerative applications. Ultraviolet (UV)-induced skin injury is characterized by excessive oxidative stress, inflammatory activation and extracellular matrix (ECM) disruption. Animal-derived collagen is limited by source-dependent heterogeneity, batch variability, and potential biosafety concerns. Here, we developed a molecularly defined recombinant human COL3A1-derived collagen-like protein, termed recombinant humanized type III collagen (rS-Col III), for the topical repair of acute UV-induced skin injury. Its engineered precursor enabled enhanced soluble expression in Escherichia coli , while the processed rS-Col III exhibited collagen-like triple-helical characteristics, consistent molecular mass and thermal behavior, good batch-to-batch reproducibility, and favorable short-term biocompatibility. In vitro, rS-Col III promoted fibroblast adhesion, proliferation, and migration, enhanced ECM-related gene and protein expression, and increased extracellular type I collagen deposition. Under UVA-induced oxidative stress, rS-Col III reduced intracellular reactive oxygen species and malondialdehyde levels while restoring superoxide dismutase activity. A cell-free ABTS assay further demonstrated modest intrinsic radical-scavenging capacity. Complementary zebrafish models showed that rS-Col III attenuated chemically induced oxidative stress and protected against UV-induced tissue injury. In an acute UV-injured mouse model, topically applied rS-Col III exhibited measurable local retention and superficial tissue distribution, improved skin hydration and barrier function, promoted epidermal and dermal structural recovery and collagen remodeling, and attenuated oxidative stress, inflammation, and matrix-degradation-associated changes. Collectively, these findings establish rS-Col III as a structurally defined and reproducibly produced collagen-like biomaterial with promising potential to support early repair of acute UV-induced skin injury through coordinated restoration of redox balance, inflammatory regulation, ECM homeostasis, and skin barrier function.

A series of transparent bio based vitrimers with strong UV shielding performance have been successfully prepared through a maleimide-thiol “click” reaction between bio-based thiols and bismaleimide (BMI). Tri and tetra functional thiol monomers (G 3SH and E 4SH) were synthesized via esterification of glycerol or erythritol with 3 mercaptopropionic acid, and subsequently cross linked with BMI to form networks containing dynamic C-S bonds. The resulting vitrimers show excellent mechanical properties (tensile strength up to 87.4 MPa), high thermal stability (initial decomposition temperature above 330 °C), and nearly complete UV blocking across the full UV range (200~400 nm). Enabled by the exchangeable C-S bonds, these materials exhibit efficient self healing (healing efficiency up to 98.7%), welding, reprocessability, and chemical recycling. Furthermore, carbon fiber reinforced polymer (CFRP) composites fabricated using these vitrimers matrices can be fully degraded under mild conditions, enabling the recovery of intact carbon fibers and the re manufacturing of composites that possess comparable mechanical performance to the original material. This work provides a viable strategy for developing sustainable, high performance, and recyclable thermosets and their composites for advanced structural applications.

To address the limitations of conventional hydrogel-based smart windows—poor phase-transition stability, low transmittance, slow response, and limited functionality—this study developed a photo-/thermo-dual-responsive hydrogel (PNAF) via a synergistic multiple-crosslinking strategy. Composed of poly(vinyl alcohol), poly(N-isopropylacrylamide), poly(acrylic acid), and Fe 3 + ions, the hydrogel relies on cooperative hydrogen bonding and coordination interactions to form a stable network with an LCST of approximately 22.0 °C. The hydrogel exhibits high visible transmittance (∼90%), rapid thermal response (2 s), photo-response (3 min), complete blockage of 365 nm UV light at 0.09 M Fe 3+ , and a solar modulation efficiency of 68.1%. Encapsulated between glass panes, the device limits water loss to approximately 0.1% over 21 days and maintains stable optical performance over 15 heating–cooling cycles and 30 days of storage. Indoor and outdoor tests confirm effective suppression of indoor temperature rise, with an estimated cooling energy saving of approximately 7.14 W per 10 m 3 . UV irradiation reduces Fe 3+ to Fe 2+ , causing a yellow-to-colorless fading that enables visual UV dose monitoring, while localized UV writing and thermoresponsive switching allow reversible information encryption and decryption. The PNAF hydrogel thus integrates light/heat modulation, UV monitoring, photo-writing, and information security, showing broad potential for energy-efficient buildings and functional devices.

Common UV filters (OBZ, AVB, OCR, OMC) widely exist in the environment and organisms, raising global concerns about their ecological and physiological risks. However, the molecular response mechanisms of higher plants to these emerging contaminants remain largely unexplored. To address this research gap, we herein employed quantitative proteomics to examine root-specific responses in pakchoi ( Brassica rapa ssp. chinensis ) following exposure to each of the four UV filters. Across all treatments, a total of 8656 proteins were quantified, with 632, 482, 251, and 393 differentially expressed proteins (DEPs) identified under OBZ, AVB, OCR, and OMC exposure, respectively. These DEPs were primarily enriched in key metabolic pathways, including reactive oxygen species (ROS) scavenging, glycolysis (EMP)–tricarboxylic acid (TCA) cycle, respiratory electron transport chain, fatty acid metabolism, and amino acid biosynthesis. All four UV filters induced pronounced oxidative stress in pakchoi roots, as indicated by elevated ROS levels and increased lipid peroxidation. Proteins involved in EMP (6-phosphofructokinase, pyruvate kinase) and the TCA cycle (isocitrate dehydrogenase, malate dehydrogenase) exhibited significant downregulation. In contrast, proteins associated with fatty acid metabolism (aldehyde dehydrogenase, long-chain fatty acid omega-monooxygenase, acyl-CoA oxidase and Delta3-Delta2-enoyl-CoA isomerase) were predominantly upregulated. These proteomic patterns suggest a potential alteration in EMP–TCA cycle, and lipid metabolic processes. Concurrently, proteins associated with antioxidant enzymes (glutathione S-transferases, peroxidases and catalases) were predominantly upregulated. These proteomic findings are consistent with the increased peroxidases and catalases enzyme activity observed at the physiological level. Collectively, these findings provide a comprehensive proteomic overview of pakchoi root responses to UV filter exposure and offer novel insights into the underlying mechanisms of phytotoxicity, and provide a reference for the breeding of crop resistant varieties to ensure agricultural productivity and food safety.

Luminescent materials used in conventional luminescent solar concentrators (LSCs) generally suffer from issues such as heavy metal toxicity, narrow spectral response ranges, significant reabsorption losses, and low near-infrared light utilization efficiency. To address these issues, this study employed a one-step hydrothermal method to synthesize nitrogen-doped graphene quantum dots (N-GQDs) with dual-band excitation capabilities in the ultraviolet and near-infrared regions. They exhibit both large Stokes shift (626 meV), anti-Stokes shift (1143 meV) and high total photoluminescent quantum yield (82.16%). Their luminescent emission peak is located at 440 nm, allowing for stable blue light emission and demonstrating significant upconversion luminescence properties. N-GQDs were encapsulated in polyvinylpyrrolidone to prepare LSCs, which were then coupled with monocrystalline silicon solar cells to construct an LSC−PV system. Under optimal conditions with a quantum dot concentration of 15 mg/mL, the LSC−PV system with dimension of 10 × 10 × 0.3 cm 3 achieved a power conversion efficiency of 0.74%, with an efficiency gain of 0.14% attributable to upconversion luminescence. This work demonstrates that N-GQDs with upconversion luminescence properties offer an approach for enhancing the performance of green, high-efficiency building-integrated photovoltaics devices.

Vanadyl porphyrins, which have central metals in the form of cations, are liable to coordinate axially with basic ligands. In the presented paper, the interaction behaviors of vanadyl octaethylporphyrin (VOOEP) with different basic ligands, viz. amines and N-heterocycles (such as pyridine, morpholine, n-butylamine, triethylamine, diethylamine, azetidine, and pyrrolidine), have been studied in detail through ultraviolet–visible (UV–vis) spectroscopy, collision-induced dissociation (CID) combined with Orbitrap mass spectrometry (MS), and density functional theory (DFT). The axial coordination ability and binding preference of VOOEP and ligands, as well as the relative stability, binding energies, and absorption spectra of the VOOEP-ligand complexes, were fully characterized in this study. The complexes involved two types of binding forms: axial coordination bonding and hydrogen bonding. It was observed that the axial coordination between VOOEP and basic ligands resulted in a decrease in intensity and red-shift of the UV–vis Soret band compared to pure VOOEP. Moreover, the axial coordination is closely correlated to the basicity and steric hindrance of the ligands. The relative stability and binding energies of the complexes are positively related to the basicity of the ligands. Additionally, besides VOOEP-ligand complexes (1:1 adducts), VOOEP-VOOEP-ligand complexes (2:1 adducts) were also observed and studied. This work offers insights that may aid petrochemists in the separation, enrichment, or selective removal of vanadyl porphyrins from petroleum samples and the investigation of porphyrin-asphaltene association behavior.

With the escalating environmental concerns associated with non-biodegradable, petroleum-derived materials, the development of eco-friendly coating alternatives has become imperative to replace conventional commercial fruit waxes, such as morpholine-emulsified formulations. This study presented the development and characterization of a composite film composed of titanium dioxide (TiO₂), rice bran wax (RW), and chitosan (CHI), and evaluated the potential of its emulsion as a postharvest coating for fruit preservation. The TiO₂/RW/CHI film exhibited enhanced mechanical and thermal performance, including improved tensile strength and thermal stability, particularly at 0.07% TiO₂. In addition, the film with 0.09% TiO₂ demonstrated favorable water solubility, as evidenced by a contact angle of 38.4°, indicating ease of cleaning from fruit surfaces. Notably, the TiO₂/RW/CHI coating can effectively promote the oxidative degradation of ethylene under ultraviolet irradiation, thereby reducing weight loss, maintaining lower soluble solids content, and delaying textural softening of cherry tomatoes during storage. These results suggest that the TiO₂/RW/CHI emulsion coating is a promising eco-friendly alternative for extending the shelf life and maintaining the quality of postharvest fruits.

In the progress of LED phosphors, the chemical stability, thermal stability, and color purity was not usually given due attention. However, the most critical problems of WLEDs are the deficit in the red-spectral region, stability, low color-rendering index (CRI) and high correlated color temperature (CCT) limit its efficiency for vivid application. Herein, the Ca 3 YGa 3 B 4 O 15 : x Sm 3+ (CYGB: x Sm 3+ ) were prepared by a solid-state route. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), diffuse reflection spectroscopy (DRS), and as well as photoluminescence (PL) spectra are used to exemplify the resulting samples. The structure and the Sm 3+ dopants in the cation-borate phosphors were quantified, signifying the importance at Ca and Y sites. Under ultraviolet radiation-induced bright deep-red emissions with high color-purity up to 97.5%. The energy-migration (EM) between the Sm 3+ ion was investigated both empirically and theoretically in the region of Sm 3+ contents. Several theoretical-models were employed to simulate the lifetime of Sm 3+ at various-concentrations, and the processes were investigated as a forced-electric dipole. The chemical-stability of CY 0.95 GB:0.05Sm 3+ has also been investigated in this work. Interestingly, the CY 0.95 GB:0.05Sm 3+ showed exceptional thermal-quenching resistance of>91.2% intensity at 400 K. The WLED containing CY 0.95 GB:0.05Sm 3+ blended with the BAM:Eu 2+ and CYAB:Tb 3+ phosphor demonstrated low CCT ≈ 3843 K and high CRI ≈ 91.9. These findings were healthier than the industrial WLED having Y 3 Al 5 O 12 :Ce 3 + and blue-LED.

In this work, a bio-derived char-forming strategy for surface fireproofing was developed. Specifically, a vinyl-modified tannic acid, (VTA) was synthesized by a ring-opening reaction between tannic acid and glycidyl methacrylate. Integration of epoxy acrylate resin, VTA and tri-(glycidyl methacrylate) phosphate (TGMA), a novel UV-curing coating was prepared, which rendered the PET sheets with superior fireproofing effect. PET samples that were surface coated with the designed UV-curing agent displayed a UL-94 V-0 rating. The peak heat release rate (peak HRR) for combustion of PET was reduced by 10.66% upon application of the flame-retardant coating in cone calorimetry tests. However, the total smoke release (TSR) increased by 48.28% due to pyrolysis of tannic acid produces 1,2,3-benzenetriol and carbon dioxide, plus the triol underwent partial combustion with the formation of large amount of particulates. The thermal behavior of cured coating revealed that the presence of high carbon content aromatic tannic acid promoting cationic crosslink and char formation ability. When 40% VTA was added into a coating, the pyrolysis char yield increased by 36.88%. Furthermore, the capability of inhibit heat transfer with the presence of VTA significantly decreased the maximum rate of weight loss for the coating by 85.97%. The increase in the VTA content promoted crosslinking density of the coating, which leads to good rigidity, outstanding abrasion resistance and remarkable water fastness.

Construction of a highly hydrophilic polymer surface with excellent long-term stability underwater is a great challenge. In this paper, a facile ultraviolet (UV) curing technique was employed to realize the three-dimensional (3D) grafting of poly(ethylene glycol) diacrylate (PEGDA, molecular weight: 400, 600, and 1000 g/mol) on a bisphenol A epoxy acrylate (BEA) sheet. The cross section morphology, surface chemical composition, and wettability of the sheets were monitored using an optical microscope, an attenuated total reflectance Fourier transform infrared spectroscope, and a water contact angle analyzer, respectively. The PEGDA-grafted epoxy sheets displayed a highly hydrophilic surface and meanwhile possessed excellent stability underwater, despite the molecular weight of PEGDA. In contrast, the PEGDA/BEA blend sheets are easily damaged underwater, due to strong swelling. In addition, the PEGDA1000-grafted BEA sheet demonstrated good antifouling performance in a natural marine environment. Nevertheless, its long-term antifouling is not satisfactory, being presumably due to hydrolysis or biodegradation of the PEG segments. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
