Recent breakthroughs in three-dimensional (3D) printing of glass have enabled precise shaping of glass structures from macro to microscale while retaining their excellent physical and chemical properties. However, current functional developments in 3D printed glass primarily focus on leveraging its intrinsic optical transparency, with limited exploration of photonics application. 3D-printed glass functionalized by quantum dots (QDs) will hold great promise for creating desired photonic functional macro- and microstructures. However, voxel-precision customization of photonic functions in 3D printed glass by the monodispersed and size-controlled QDs is fundamentally conflict with the high-temperature sintering process required in 3D printed glass. Here, we present a simple, cost-effective method for creating a library of QDs functionalized 3D-printed glasses with tunable UV-VIS-IR photoluminescence (PL) by printing nanoporous glass (NG) followed by low-temperature nanoscale engineering of QDs growth. The integration of uniform and size-controlled QDs imparts 3D printed glass with fine tuning in composition, architecture, and photonic functionalities, while nanoscale engineering of the micro-environment enables precise tailoring of various QDs with enhanced optical performance and stability. This universal approach establishes a benchmark for 3D-printed functional glasses with advanced photonic capabilities.

Polymer-based radiative cooling materials combine flexibility with zero-energy cooling capabilities, offering promising solutions for advanced thermal management textiles in high-temperature environments. However, prolonged exposure to ultraviolet (UV) radiation triggers photodegradation, leading to yellowing and a consequent reduction in cooling performance. This study proposes a fabrication strategy for a flexible cooling textile based on a triband optical response. A hierarchically porous micronano membrane is designed to minimize solar heating by reflecting sunlight and simultaneously facilitate heat dissipation through strong mid-infrared emission. Concurrently, zinc oxide nanoparticles are incorporated to achieve efficient UV shielding. Due to the synergistic UV shielding between nanoparticles and the porous matrix, the fabric achieves outstanding radiative cooling (95% solar reflectance, 92% mid-IR emissivity) with a remarkably low ZnO loading of only 0.5%. This approach effectively avoids the discoloration and stiffening of the membrane typically caused by high filler concentrations in conventional methods, while additionally enhancing breathability and reducing cost. Outdoor tests demonstrate that the fabric achieves a subambient cooling effect of 5.6 °C and exhibits an exceptional Ultraviolet Protection Factor (UPF ≈2000). Furthermore, it maintains highly efficient cooling performance even after 400 h of UV exposure. The fabric’s enhanced mechanical strength, water resistance, and breathability work synergistically to ensure durability and provide comprehensive protection for the wearer. This cost-effective, scalable, and durable radiative cooling textile thus holds significant potential for applications in healthcare, outdoor labor, and defense.

Developed stepwise modification strategy for UV-curable gelatin-based conductive hydrogels. • Optimized water/glycerol solvent system to achieve outstanding long-term moisture retention. • Constructed hybrid ionic-electronic networks via carboxylated CNT reinforcement. • Demonstrated stable wide-range strain sensing for wearable human motion monitoring. Conductive hydrogels serve as core matrix materials for flexible strain sensors, but conventional hydrogels suffer from rapid water loss under ambient conditions and an inherent trade-off between mechanical and conductive properties. This work develops a gelatin/poly(acrylic acid) composite conductive hydrogel synergistically functionalized with glycerol for moisture retention, aluminum salts for ionic crosslinking, and carboxylated multi-walled carbon nanotubes (c-MWCNTs) for reinforcement. Moisture retention is optimized by tuning the water-to-glycerol ratio, and three aluminum salts are compared to identify the optimal crosslinker. Multi-dimensional characterizations reveal interfacial interactions and microstructural evolution, and the regulatory effect of c-MWCNTs loading on electromechanical and sensing properties is systematically investigated. At a water-to-glycerol ratio of 50:50, the hydrogel retains over 82% water after 7 days of ambient storage. The aluminum chloride system exhibits the optimal ionic conductivity and balanced mechanical performance. With 0.025 wt% c-MWCNTs uniformly embedded via hydrogen bonding and coordination interactions, both conductivity and tensile toughness are significantly enhanced. The resulting flexible strain sensor features stable sensitivity over a wide strain range and excellent fatigue resistance, enabling accurate monitoring of human joint motions and showing great potential for wearable health monitoring.

To improve the inherent brittleness of poly( l -lactide) (PLLA) and obtain a kind of UV-curable bio-based PLLA with excellent adhesion and ductility, castor oil (CO) was used to modify PLLA by a novel and simple pathway. After a series of castor oil-poly( l -lactide) oligomers (COPLLA) were prepared via the ring-opening polymerization of l -lactide (LLA) with CO as the initiator, a kind of bio-based castor oil-modified PLLA with chemical cross-linked network and PLLA branched chain (CCPLLA) was obtained through UV-initiated thiol-ene reaction between COPLLA and pentaerythritol tetra(mercaptoacetate) (PETMA) as the crosslinker. CCPLLA was respectively measured by Fourier transform infrared (FTIR) spectroscopy and extraction, showing the good UV-curing effect. With increasing the molecular weight of PLLA branched chain, the glass transition temperature of CCPLLA rose, meanwhile CCPLLA gradually transformed from an amorphous state to having crystalline behavior, which determined by differential scanning calorimetry (DSC) and polarized optical microscopy (POM). The mechanical and adhesive properties of CCPLLA first increased significantly and then slightly decreased with increasing the length of PLLA branched chain. Among them, CCPLLA-18 exhibited the best comprehensive performance such as tensile strength, ductility, adhesive property, water resistance, thermal stability and optical transmittance. Therefore, the UV-curable bio-based castor oil-modified PLLA has application potential in the field of adhesive, particularly for bonding of heat-sensitive substrates and those requiring high transparency.

Nitrate is always present as the concomitant component during the advanced treatment of refractory organic emerging contaminants. The simultaneous achievement of effective denitrification is an ideal goal for environmentally friendly treatment, especially for those nitrogen-containing compounds. Herein, the performance and mechanisms for simultaneous removal of CBZ and nitrate by UV 254nm /S(IV) process were investigated. Results demonstrated that CBZ and NO 3 – - N could be efficiently removed together, and denitrification was mainly contributed by e aq - , while CBZ degradation was driven by e aq - (55.4%) and •OH (30.4%) collectively. Moreover, the presence of nitrate exerted more significant influences on CBZ degradation than the competition nitrate faced on its own. The removal of CBZ and nitrate both increased with the rise in solution pH and the decrease in their respective initial concentrations. However, the denitrification was accelerated by increasing sulfite concentration while CBZ degradation was obtained at an optimum sulfite concentration. Although nitrate could quench the hydrated electrons to impede CBZ degradation, the •OH radicals produced by nitrate photolysis could compensate partially for the loss. The final product of nitrate was almost completely the nitrogen gas, while both the reduction pathway and oxidation pathway of CBZ degradation were proposed based on DFT calculation and UPLC/MS analysis. The detoxification advantages of CBZ degradation were also revealed from the UV/sulfite process, and the intermediates obtained from reduction reactions generally showed lower toxicity than those from oxidation reactions. This study may provide insights into developing efficient and environmentally friendly advanced methods for the treatment of emerging contaminants.

Flexible ultraviolet (UV) photodetectors have broad application prospects in wearable electronics and low-power optoelectronic systems. In this work, a self-powered UV photodetector based on a γ-CuI/AZO p-n heterojunction was successfully fabricated on a flexible polyethylene naphthalate substrate. Both γ-CuI and AZO films exhibit high visible-light transmittance with optical bandgaps of 3.03 eV and 3.28 eV, respectively, rendering them suitable for UV detection. The device demonstrates distinct rectification behavior in the dark and a markedly enhanced photoresponse under 365 nm UV illumination, achieving stable self-powered operation at 0 V bias. Under a 0 V bias and an incident power density of 103.2 mW/cm 2 , the device demonstrates rise and decay times of 306 ms and 116 ms, respectively. At 33.4 mW/cm 2 , the device achieves a responsivity of 4 mA/W and a specific detectivity of 2.62 × 10 11 Jones, confirming its effective self-powered UV detection capability. Furthermore, cyclic bending tests under a fixed 5-mm radius curvature revealed that the device maintains distinguishable photoresponse after 500 bending cycles, demonstrating robust mechanical tolerance and reliable photodetection under fatigue deformation. This work provides a feasible route for the construction of flexible self-powered UV photodetectors based on p–n heterojunctions.

The development of intrinsically photostable polymers through molecular design remains a persistent challenge in materials science. Here, a series of polyethylene terephthalate-1,4-cyclohexanedimethanol (PETG) copolyesters with precisely tailored trans-1,4-cyclohexanedimethanol (trans-CHDM) contents were synthesized via one-pot copolymerization. The successful stereochemical control of CHDM units was verified by 1 H-NMR spectroscopy. For the first time, the structure-property relationship between the trans-CHDM content and the UV-aging resistance of PETG was systematically established. Increasing the trans-CHDM content was shown to increase the glass transition temperature and the thermal stability of the copolyesters. Remarkably, higher trans-CHDM levels led to significantly improved photostability, as evidenced by superior mechanical retention, reduced chain scission, and minimal structural degradation during prolonged UV-irradiation. Mechanistic investigations revealed that the increased UV resistance stems from a narrowed optical bandgap and, more critically, an efficient photothermal conversion pathway. The latter is facilitated by heightened intramolecular friction in high-trans polymers, which promotes nonradiative energy dissipation and effectively mitigates photooxidative damage. Within the series, PETG-40-80% achieves an optimal balance between UV durability and mechanical performance, positioning it as a promising candidate for high-performance, weather-resistant applications. This work highlights the stereochemical control of comonomers as a potent strategy for increasing the photostability of polyester materials.

A UV-curing-assisted dip-coating strategy enables controllable fabrication of ultrathin YSZ membranes on porous anodes. • The membrane-forming mechanism of photocurable resin slurries is systematically elucidated. • The thickness of electrolyte membranes is precisely regulated, with the minimum down to 2 μm. • NiO-YSZ/YSZ/LSM cells with ultrathin electrolytes achieve 750 mW cm −2 at 800 °C with good stability. Ultrathin yttria-stabilized zirconia (YSZ) electrolytes can reduce ohmic losses and improve solid oxide fuel cell (SOFC) efficiency, yet fabricating dense, gas-tight micrometer-scale membranes on porous supports remains challenging. Herein, a UV-curing-assisted dip-coating strategy is developed for the controllable fabrication of ultrathin YSZ membranes. Rational regulation of slurry wettability and rheology mitigates capillary-driven infiltration into the porous support, whereas UV-triggered cross-linking offers transient structural stabilization to preserve membrane integrity throughout the drying process. Based on thermal decomposition analysis, a stress-managed sintering process is established to obtain dense and defect-free YSZ electrolyte membranes with a thickness of ∼2 μm. The optimized single cell delivers a peak power density of 750 mW cm −2 at 800 °C and over 140 mW cm −2 at 650 °C, respectively, together with excellent operational and thermal cycling stability. These results demonstrate great potential of UV-curing-assisted dip coating strategy for fabricating ultrathin electrolyte membranes for high-efficiency SOFCs.

ZnO nanoparticles enable photoresponsive ionic hydrogels with light memory • Light-memory hydrogel TENG records recent UV exposure history • Temporal UV exposure is reconstructed from evolving material states • WMPT-Mamba identifies five UV irradiance levels with 98.6% accuracy • Self-powered wearable patch enables real-time UV monitoring and risk warning Prolonged solar ultraviolet (UV) exposure poses a growing occupational health burden, particularly for outdoor workers, yet personal UV risk is inherently cumulative and difficult to capture using sensors that primarily report instantaneous light conditions. Photoresponsive triboelectric nanogenerators (Photo-TENGs) offer a self-powered route for wearable light sensing, but their material responses have largely been exploited to enhance electrical output during illumination, leaving post-illumination state evolution underutilized as a source of exposure-history information. Here, a light-memory hydrogel triboelectric sensor (LM-gel-TENG) is developed to retain recent UV exposure through time-dependent material-state evolution. A ZnO-integrated ionic hydrogel is designed to synergistically combine mechanical adaptability, ion transport, and photoinduced charge regulation, enabling electrically readable UV-responsive triboelectric signals and persistent electrical-state enhancement after illumination. An output voltage of 228 V and a maximum photoinduced voltage enhancement of 44.86% are achieved by the LM-gel-TENG. The evolving signals are reconstructed into dark-light-memory pulse triplets, and a Wavelet-Markov Pulse-Triplet Mamba framework is developed to distinguish five UV irradiance levels with 98.6% accuracy. A mobile platform further enables real-time signal acquisition and visualization, post-event classification of five predefined UV irradiance levels, digitally calculated cumulative-dose display, and exposure-risk indication, supporting personalized wearable UV monitoring. By decoding post-illumination material-state evolution as temporal exposure information, this work advances Photo-TENGs toward exposure-history-aware self-powered sensing and offers a pathway for more individualized UV exposure awareness and proactive protection in populations facing sustained outdoor work. A light-memory hydrogel triboelectric sensor converts UV-induced material-state evolution into decodable electrical signals, achieving 40.96% voltage enhancement and light-signal retention. Integrated with WMPT-Mamba recognition and a mobile app/LED warning platform, the intelligent patch enables real-time personalized UV exposure monitoring and risk warning.

Self-healing polyurethane (PU) elastomers will greatly extend the service life of key components, reduce maintenance costs, and promote sustainability. However, dense hydrogen bonds cannot quickly recover after stretching, causing permanent deformation, while high-temperature and long-duration curing are required for their crosslinking. Therefore, dual crosslinked networks are designed herein to achieve self-healable, high-resilience and UV-curable polyurethane-urea elastomers (PUU-SS-Zn), using polycarbonate diol (PCDL) as the soft segment for entropic elasticity, cystamine (Cy) as a chain extender for disulfide bonds and urea-linked hydrogen bonds, 2-hydroxyethyl acrylate (HEA) as end-capping groups for rapid UV-curing, ZnCl 2 for metal coordination bonds. The resultant elastomers are UV-cured within 100 s, exhibit a transmittance >92%, tensile strength of 11.8 MPa, and elongation at break of 2423%. More importantly, it achieves nearly 100% resilience at 500% strain within 5 s, realizes 99.6% resilience at 1000% strain within 5 min, and maintains 90.2% after multiple cycles. Surface scratches disappear within 30 min at 60 °C, and the self-healing efficiency reaches 93% after 8 h at 80 °C. This self-healable, high-resilience and UV-curable polyurethane-urea elastomer shows great application potentials in flexible sensors and wearable devices.

High-temperature energy systems require robust functional coatings and sensing materials capable of operating under extreme thermal and oxidative environments. The polymer-derived SiHfBCN ceramics system shows strong potential owing to their outstanding thermal stability and oxidation resistance. However, achieving compatibility with high-resolution patterning remains challenging due to the lack of suitable photosensitive precursors. Herein, a photoresponsive quinary SiHfBCN preceramic resin is rationally designed via sequential grafting of acrylate photosensitive units onto the polymer backbone, enabling efficient photolithography and dense ceramic film formation. Compared with conventional thermal processes, UV curing significantly enhances microstructural order and promotes the formation of conductive networks, yielding a low resistivity of 0.087 Ω·m at 1200 °C. Further incorporation of carboxylated multi-walled carbon nanotubes reduces the resistivity to 4.49 × 10 −3 Ω·m by constructing chemically coupled conductive networks. The ceramic films exhibit a Young's modulus of 93.38 ± 0.50 GPa and a hardness of 9.34 ± 0.09 GPa. Notably, negligible changes in internal resistivity are observed after 50 h oxidation at 1200 °C in air, owing to a self-sealing oxide layer reinforced by carbon nanotube–oxide nano-pinning interfaces. This work elucidates the synergistic roles of UV curing and carbon nanotube incorporation in tailoring phase evolution, electrical transport, and oxidation stability in complex polymer-derived ceramic systems, highlighting the strong potential of photo-induced SiHfBCN ceramic films as integrated conductive and self-sensing coatings for high-temperature energy applications.

Effective thermal management is essential for maintaining habitable conditions and system reliability in environments with extreme diurnal temperature variations. However, conventional thermoregulatory materials fail to deliver bidirectional thermal regulation under such conditions. Radiative coolers often cause excessive nocturnal overcooling due to continuous heat loss. Conversely, pure thermal insulators cannot actively dissipate accumulated heat during the day. Prolonged UV exposure further accelerates material degradation, compromising long-term performance stability. Overcoming these compounding environmental challenges necessitates a unified design strategy. Here, we present UV-resistant hierarchical structured thermoregulatory (HiST) coatings that synergistically integrate high-performance radiative cooling and superior thermal insulation within a scalable architecture. The coatings show outstanding thermal-optical properties: 97.58% solar reflectance with robust UV rejection, 97.34% infrared emissivity, and 35 mW m −1 K −1 thermal conductivity. Field tests in extreme environments reveal ∼19.8°C temperature reduction relative to an uncoated control and ∼4.1°C peak nighttime interior temperature elevation above the ambient, buffering interiors against thermal shocks. This work establishes a robust materials platform for effective thermal management in applications ranging from energy-efficient buildings to spacecraft and habitats for extreme terrestrial and space environments.
