Considering the health and safety effects of the active components in current sunscreens has inspired the enthusiasm for developing biocompatible alternatives, especially from nature. However, natural active ingredients have inherent drawbacks, such as dark-colored lignin and easily oxidized polyphenols, which are difficult to meet the requirements of smart sunscreens. Integrating two or more natural sunscreens in a single unit can overcome the shortcomings of a single active ingredients and synergistically enhance ultraviolet (UV) radiation protection. Herein, a composite microsphere (HCAS) was fabricated by incorporating dopamine modified lignin, silk fibroin, phenylboronic acid modified hyaluronic acid and chlorogenic acid through self-crosslinking of boric acid ester bonds and using genipin as assistant cross-linker. This multi-component coordination strategy imparts HCAS microspheres with superior UV protection performance and photostability under UV exposure. The remarkable properties of HCAS are evidenced by its high sun protection factor (SPF) of 55 when incorporated at 10% into a base cream, representing a significant improvement in color clarity compared to lignin-based formulations. Notably, HCAS exhibited exceptional antioxidant activity, capable of effectively eliminating reactive oxygen free radicals (DPPH•, OH• and O₂• − ). Furthermore, HCAS microspheres demonstrate excellent interfacial activity, functioning as an efficient Pickering stabilizer under various conditions. In vitro biological evaluations confirmed that HCAS not only has good biocompatibility but also shows the potential to promote cell growth. This study demonstrates that integration of multi-component natural ingredients for synergistically enhancing UV performances is an effective strategy for future sunscreens development.

A liquid crystal monomer (BLMA-1) containing a biphenyl mesogenic unit and acrylate groups was designed and synthesized, and a temperature-regulated UV curing strategy was employed. The strategy is characterized by pre-aligning the liquid crystal monomer into an ordered template through the curing temperature, followed by photopolymerization. The photopolymerization process plays a dual role: on the one hand, it locks the mesoscopic ordered structure in situ, and on the other hand, it further enhances the ordering of the cross-linked network through polymerization-induced crystallization. The phase behavior and structural evolution of the monomer during the pre-curing stage were studied using polarized optical microscopy (POM) and variable-temperature X-ray diffraction (XRD). Subsequently, the properties of resins cured at different temperatures ranging from 140 °C to 180 °C were systematically characterized. The results demonstrate that photopolymerization not only preserves the mesoscopic order of the liquid crystal phase but also significantly enhances the ordering of the cross-linked network through the polymerization-induced crystallization mechanism, leading to the formation of a semi-crystalline cross-linked structure with relative crystallinity ranging from 14.98% to 22.79%. Importantly, the thermal conductivity (0.298–0.536 W·m −1 ·K −1 ), thermal stability (T 5% = 294.7–380.1 °C), glass transition temperature (T g = 126.3–131.1 °C), and mechanical properties of the material are closely related to the ordered structure formed during the curing process. By optimizing the curing temperature to 150 °C, an ideal balance between ordering (crystallinity = 22.79%) and cross-linking density (1.4105 × 10 4 mol·m −3 ) was achieved, resulting in a liquid crystal polymer network that combines high thermal conductivity (0.536 W·m −1 ·K −1 ), good mechanical strength (fracture strength 26.57 MPa), and excellent thermal stability. This work provides a theoretical and experimental framework for designing liquid-crystalline polymers with synergistically enhanced properties via photopolymerization, offering a promising strategy for developing advanced polymer thermal-management materials.

This study presents a multifunctional hydrogel engineered by integrating carbon dots (CDots) and lanthanide metal ions (Ln3+), which exhibits tunable multicolor fluorescence under dual-wavelength UV excitation (254 nm and 365 nm). Systematic characterization via scanning electron microscopy (SEM), mechanical analysis, and fluorescence spectroscopy revealed three key features: distinct chromatic transitions between excitation wavelengths, favorable mechanical robustness, and long-term stability. The programmable fluorescence behavior, achieved through precise Ln3+ stoichiometric control and CDot-mediated energy transfer mechanisms, enables optical encryption with dual-excitation modes. Furthermore, the hydrogel demonstrates visual ion detection capabilities, exhibiting rapid fluorescence responses toward Zn2+ and K+ via specific coordination interactions. This dual-functional hydrogel advances the development of intelligent materials for anti-counterfeiting technologies and environmental monitoring applications.

This study developed cholesteric liquid crystal broadband reflective films using zinc oxide nanoparticles (ZnO NPs) and homotriazine UV-absorbing dye (UV-1577) to enhance infrared shielding. Unlike benzotriazole-based UV absorber UV-327, which suffers from volatility and contamination, UV-1577 exhibits superior compatibility with liquid crystals, higher UV absorption efficiency, and enhanced processing stability due to its larger molecular structure. By synergizing UV-1577 with ZnO NPs, we achieved a gradient UV intensity distribution across the film thickness, inducing a pitch gradient that broadened the reflection bandwidth to 915 nm and surpassing the performance of previous systems using UV-327/ZnO NPs (<900 nm). We conducted a detailed examination of the factors influencing the reflective bandwidth. These included the UV-1577/ZnO NP ratio, the concentrations of the polymerizable monomer (RM257) and chiral dopant (R5011), along with polymerization temperature, UV irradiation intensity, and irradiation time. The resultant films demonstrated efficient ultraviolet shielding via the UV-1577/ZnO NPs collaboration and infrared shielding through the induced pitch gradient. This work presents a scalable strategy for energy-saving smart windows.

To endow silk with multifunctionality and expand its application fields, the silk fabric was treated with protocatechualdehyde to prepare a novel silk fabric with Schiff base structure (CAT@Silk). Then, CAT@Silk was immersed in iron (III) solution to chelate Fe 3+ to obtain flame retardant , antibacterial and UV-resistant silk fabric (CAT@Fe@Silk). Compared with the limiting oxygen index (LOI) value of the original silk, the CAT@Fe@Silk increased from 23.3 % to 35.1 %, and remained 32.4 % even after 20 laundering cycles (LCs), indicating excellent flame retardant durability. The UV protection coefficient of CAT@Fe@Silk was 67.74, which was higher than that of the original sample (21.02). In addition, CAT@Fe@Silk had good antibacterial effects against Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ). This work constructed a dynamic cross-linking network that mimicked the adhesion of mussels generating from the complexation of catechol groups and Fe 3+ ions (catechol-Fe 3+ ), which not only endowed silk fabric with good flame retardancy, but also with UV resistance and antibacterial properties, demonstrating good potential application.

The ultraviolet (UV) shielding properties of food packaging materials have garnered significant attention for mitigating issues such as off-flavors, discoloration, and nutrient degradation. However, achieving effective UV protection while maintaining sustainability and performance in packaging materials remains a challenge. Herein, a novel multifunctional composite coating with UV-shielding properties was prepared using cellulose nanocrystals (CNCs) and sodium lignosulfonate (SL) as functional components and polyvinyl alcohol (PVA) as a cross-linking agent. Notably, the SL-4/C/P coated paper prepared using the coating with an SL/CNCs mass ratio of 4:1, exhibited excellent UV-shielding efficiencies (98 % shielding in the UVA region and almost completely block the whole UVB region), enhanced mechanical properties (126 % increase in tensile index and 308 % improvement in folding endurance), lower Cobb 30 value (decreased from 66 g/m 2 to 56 g/m 2 ), and reduced air permeability (decreased from 124 mm/s to 52 mm/s) compared to uncoated paper. This work offers a sustainable and promising strategy for balancing UV-shielding performance with the functional properties of food packaging paper, opening new avenues for the high-value application of CNCs and SL in the papermaking industry.

The anti-twist performance of flexible electronic devices prepared on fabrics is often limited by the degree of bonding between the electronic material and the fabric. This work addresses the issue of limited bonding strength between traditional semiconductor oxide nanomaterials and fabric substrates, by enhancing the bonding ability between ZnO nanoparticles and fabric fibers through Prussian blue pretreatment. The test results show that after appropriate Prussian blue treatment, the anti-twist performance of the ZnO nanoparticle UV detectors prepared on fabric substrates has significantly improved. The on/off ratios of the obtained ZnO/PB device after twisting 100, 200, 300, 600, and 900 times are 37.8, 26.7, 28.5, 7.5, and 30.9, respectively, while the ZnO/PVDF device loses its detection ability after twisting 600 times. Even after twisting to 540°, the ZnO/PB device can still exhibit obvious UV response characteristics, with a photocurrent of about 0.09 nA. Compared with those of untreated devices and devices bonded with PVDF, the anti-twist performance of the ZnO/PB device has been significantly enhanced. These results provide a data foundation and research ideas for the development of wearable optoelectronic devices based on traditional semiconductor oxide materials in the future.

This study proposed an innovative strategy integrating microchannel assisted flow synthesis with UV initiated polymerization to prepare artemisinin imprinted polymers (MIPs), enabling precise control over microsphere morphology and binding site uniformity. The intermolecular hydrogen-bonding between artemisinin and functional monomers was validated via Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Photoelectron Spectroscopy (XPS), and Single Site Nuclear Magnetic Resonance (SSNMR), and was successfully engineered into the polymer microspheres. When the microsphere diameter was reduced by 50%, the adsorption capacity increased by 65%. BET results indicated that adjusting the prepolymer solvent ratio modulates the pore structure of MIP microspheres, boosting adsorption capacity by approximately 62%. Furthermore, optimizing the imprinting site precision by adjusting the crosslinker ratio elevated the selectivity factor from 1.19 to 4.46. The precisely tuned MIP demonstrated exceptional artemisinin binding capacity (up to 42.8 mg/g),3.73-fold selectivity toward artemisinin analogues, and rapid equilibrium (40 min, pseudo-second order kinetics). Notably, the microfluidically synthesized MIP retained 94% adsorption efficiency after eight regeneration cycles. Molecular simulations revealed the adsorption mechanism: customized recognition sites on the imprinted microspheres form strong hydrogen bond interactions with artemisinin. Energy difference calculations validated the correlation between simulated and actual adsorption energies, further substantiating this conclusion. This study pioneered the integration of flow chemistry and molecular imprinting technology, establishing a scalable platform for designing robust, high capacity molecularly imprinted polymers suitable for bioactive compound extraction.

Polylactic acid (PLA) suffers from inherent brittleness, flammability, and poor UV resistance, which significantly limit its practical applications. Conventional additives often exhibit single functionality and tend to reduce the crystallinity of polymers, leading to a deterioration in mechanical properties. In this study, a multifunctional bio-based additive (HVB) was synthesized by introducing amide groups into vanillin-modified hexachlorocyclotriphosphazene. The molecular interactions formed between the amide groups in HVB and PLA further promoted the enhancement of PLA crystallinity. Consequently, both the tensile strength and elongation at break of PLA were remarkably improved. When the HVB loading was 3 wt%, the composite exhibited a 3.4% increase in tensile strength and a 75.8% improvement in elongation at break, while achieving a UL-94 V-0 flame-retardant rating. Furthermore, molecular simulations combined with experimental characterizations were employed to elucidate the carbonization and free-radical-trapping mechanisms of the flame retardant.

As emerging global environmental contaminants, organic ultraviolet absorbers (OUVAs) are widely used in personal care formulations and exhibit environmental persistence and potential bioaccumulation. Among these compounds, 2-ethylhexyl salicylate (EHS) and homosalate (HMS) are the most frequently used salicylate-type UV filters in cosmetic formulations. Although an increasing number of studies have demonstrated their environmental hazards, little is known about the molecular mechanisms underlying their cytotoxicity in mammalian systems, a fundamental knowledge gap for both human health protection and the development of more environmentally friendly consumer goods. In this study, we used mouse embryonic fibroblasts (MEFs, 3T6) and zebrafish as models to assess the toxicological phenotypes of EHS and HMS in vitro and in vivo, respectively. We found that both EHS and HMS induced cellular damage characterized by oxidative stress, disrupted intracellular calcium homeostasis, mitochondrial impairment, and DNA damage. Importantly, molecular analyses further suggested the concurrent activation of two distinct regulated cell death programs: pyroptosis, as suggested byCaspase-11-mediated GSDMD cleavage, and necroptosis, as suggested byZBP1-RIPK3-Caspase-8-mediated MLKL phosphorylation. The in vitro data have been partially validated at the level of gene expression and in developmental toxicity in the zebrafish model, providing some in vivo phenotypic and molecular correlates. While the upstream events were experimentally verified, the causal links among them remain to be further elucidated. Taken together, this work suggested that OUVA-induced toxicity is not limited to isolated oxidative damage, but may also involve the activation of two different cell death programs. These findings provide important molecular clues to understanding the potential health and ecological risks of widely used UV filters and offer a scientific basis for their more environmentally friendly safety evaluation and regulatory management, which are crucial for advancing more sustainable chemistry and safer consumer goods.

All-inorganic perovskites, with their low-cost, simple processes and superior heat stability, have become potential candidate materials for photodetectors (PDs). However, they have no representative responsivity in the deep-ultraviolet (UV) wavelength region. As a new-generation semiconductor, gallium oxide (Ga2O3), which has an ultrawide bandgap, is appropriate for solar-blind (200 nm–280 nm) deep-UV detection. In this work, ultrawide-bandgap Ga2O3was introduced into an inorganic perovskite device with a structure of sapphire/β-Ga2O3/Indium Zinc Oxide (IZO)/CsPbBr3. The performance of this perovskite PD was obviously enhanced in the deep UV region. A low-cost, vacuum-free Mist-CVD was used to realize the epitaxial growth of β-Ga2O3film on sapphire. By introducing the Ga2O3layer, the light current of this heterojunction PD was obviously enhanced from 10−8to 10−7, which leds its detectivity (D*) to reach 1.04 × 1012Jones under a 254 nm light illumination with an intensity of 500 μW/cm2at a 5 V bias.

Dual-mode excitation properties were introduced in Sm3+ doped Sr2CaMoO6 prepared by a high temperature solid state reaction technique. Two ways are available to generate white light in the single-component phosphor activated by Sm3+ ions. Warm white light can be obtained from Sr1.995Sm0.005CaMoO6 phosphor pumped by 380 or 411 nm excitation energy. The full visible spectral emission of the single-phase phosphor comes from the high and low level emission lines of Sm3+ ions as well as the intrinsic luminescence of MoO6 group. It is also competitive as yellow-emitting phosphor for blue pumped white LEDs and gives three emission bands at 567, 603, and 650 nm, presenting yellow luminescence upon 466 nm radiation. The 650 nm red emission band corresponding to 4G5/2 → 6H9/2 transition of Sm3+ can make its color rendering index better. The excellent photoluminescence of Sr2CaMoO6 is related to the partial tilting CaO6 octahedral and the lowered symmetry were confirmed by General Structure Analysis System. Band gap of Sr2CaMoO6 estimated from the diffuse reflection spectra and also calculated by CASTEP mode shows its semiconducting character. All the results show that the Sr2–xSmxCaMoO6 phosphors have considerable potential for applications in near UV LED or pumped by blue LED chip.
