s Ionogels, as a functional material with ionic conductivity, flexibility and environmental stability, are widely used in the field of flexible sensors. However, conventional ionogels often face problems such as insufficient adhesion and unstable sensing performance in wet or underwater scenarios. Hence, this study prepared a versatile ionogel sensor exhibiting environmental stability and strong adhesion, suitable for underwater sensing, via UV-initiated polymerization of tert-butyl acrylate (TBA), methoxyethyl acrylate (MEA), and 2,2,3,4,4,4-hexafluorobutyl acrylate (HFBA) monomers in 1-butyl-3-methylimidazolium bis (trifluoromethylsulfonyl) imide ([BMIM][TFSI]) as the dispersion medium. Hydrophobic TBA and HFBA monomers effectively block water molecule penetration into the gel, granting excellent anti-swelling properties (mass retention > 90 % in various solvents). Fluorine-containing segments in the gel enhance thermal stability (only 2 % mass loss was observed after 21 days at 80 ℃) and impart underwater self-healing ability and high adhesion strength. The ionic liquid is uniformly distributed in the three-dimensional network structure of the gel, providing excellent electrochemical performance and endowing the gel with rapid response capability (response time of only 3 ms). This work provides a promising approach for the application of ionogel sensors in wearable devices in humid environments.

To address the issues of poor wettability, low separation flux, and limited functionality in traditional separation membranes, this study developed an eco-friendly, multifunctional composite membrane based on polylactic acid (PLA/PVP-PDMS/Fe 2 O 4 /TiO 2 ) by combining electrospinning with electrostatic spraying technology. Through morphological and structural characterization, it was demonstrated that the composite membrane exhibits a multiscale rough structure, combining magnetic responsiveness with UV resistance. The results demonstrate that the composite membrane exhibits outstanding oil–water separation performance, achieving a separation flux of up to 4882.15 L·m −2 ·h −1 and a separation efficiency of 99.53%. With a water contact angle as high as 155.5° and a rolling angle as low as 4.5°, it displays superhydrophobic properties and excellent anti-fouling characteristics. In addition, this composite membrane demonstrates excellent potential for treating wastewater in corrosive environments, maintaining a hydrophobic angle above 150° across various corrosive conditions.

A new polyfunctional acrylate monomer (COPERAA) was synthesized from castor oil and utilized as a sustainable reactive diluent for UV-curable materials. Firstly, experimental conditions for the synthesis of the monomer were optimized and its chemical structures were confirmed by FT-IR, 1 H NMR, and ESI–MS. Subsequently, the effect of COPERAA on biobased content, viscosity, and volumetric shrinkage of the obtained AESO resins were studied. After that the effect of COPERAA on thermal, mechanical, coating, and swelling properties of the resulting UV-cured bioresins were investigated. Furthermore, UV-curing behaviors of the resultant bioresins were evaluated by real-time IR. Compared with the petroleum-based trimethylolpropane triacrylate (TMPTA) diluent, the biobased COPERAA diluent showed better performance on the biobased content, volumetric shrinkage, adhesion, and final C C conversions of the resulting AESO materials and better compatibility with the AESO prepolymer. Therefore, the developed oil-based diluent shows promise to be applied in UV-curable materials.

A novel phosphorous-containing acrylated epoxidized soybean oil-based (P-AESO) resin was developed via the ring-opening reaction of epoxidized soybean oil (ESO) with diphenylphosphinic chloride (DPPC), followed by acrylation of the resulting groups. The chemical structure was characterized by Fourier transform infrared spectroscopy (FT-IR), and 1 H nuclear magnetic resonance ( 1 H NMR). Subsequently, the viscosity and volumetric shrinkage of the obtained P-AESO resins were studied. Then the oligomer was formulated into UV-curable coatings, and the mechanical, thermal, and coating properties of the resulting UV-cured bioresins were studied by tensile testing, dynamic mechanical thermal analysis (DMA), thermogravimetric analysis (TGA) coupled with FT-IR spectroscopy (TGA-FT-IR), hardness, adhesion, pencil hardness and chemical resistance. Furthermore, the UV-curing behavior of the P-AESO resin was determined by real-time realtime infrared (RT-IR). Meanwhile, compared with coating from acrylated epoxidized soybean oil (AESO), the P-AESO system coatings showed better volumetric shrinkage, excellent adhesion, and enhanced thermal and glass transition temperature ( T g ) while maintaining reasonably final C = C conversions and cross-link density. For instance, the obtained P-AESO/trimethylolpropanetriacrylate (TMPTA) 20 material possessed a volumetric shrinkage of 4.1%, T g of 115.6°C, char yield of 9.47%, and final C = C conversions of 81.4% respectively, which exhibited superior values than that of the AESO/TMPTA20 material. The improvement of the P-AESO coating performances could contribute to the architectures that combined the structural features of phosphorous-containing rigid benzene. The developed P-AESO resin is promising for applications in the UV-curable coatings.

In this study, in order to get near-ultraviolet-excitable cyan-emitting phosphors for white light-emitting diodes (LEDs), Ce 3+ ions were successfully doped into the newly discovered Ca 2 YHf 2 Ga 3 O 12 (CYHG) matrix through the high-temperature solid-state reactions. The obtained samples exhibited a broad excitation band in the 250–450 nm wavelength range centered at about 346 nm and 398 nm, and they showed an intense cyan emission band in the 410–600 nm wavelength range peaking at about 479–485 nm Ce 3+ doping concentration dependent luminescence properties in CYHG: x Ce 3+ phosphors were studied, and the optimal Ce 3+ doping concentration was found to be x = 0.04. Furthermore, the energy transfer mechanism between Ce 3+ ions was confirmed as the dipole-dipole interaction, which induced the observed concentration quenching effect. Notably, upon excitation by near-ultraviolet light at 398 nm, the CIE chromaticity coordinates of CYHG:0.04Ce 3+ sample were obtained to be (0.182, 0.276), which were located in the cyan color range. Besides, the internal quantum efficiency (IQE) values of these CYHG: x Ce 3+ phosphors were measured, and the highest one reached up to 26%. These newly developed cyan-emitting CYHG:Ce 3+ phosphors might find potential application in high-color-rendering white LEDs by covering the so-called cyan gap.

The inherent safety issues of commercial organic liquid electrolytes make it hard to deploy them in lithium metal batteries. By contrast, nanocomposite polymer electrolytes (NCPEs) can not only suppress the growth of lithium dendrites but also have the functions of separators to substitute the liquid electrolytes. In this work, a kind of NCPE was designed by in situ hydrolysis of tetrabutyl titanate to form in situ TiO2 nanoparticles throughout the UV curing cross-linked polyurethane acrylate network, and the addition of an ionic liquid as a plasticizer further enhanced the safety property of the NCPE due to its intrinsic excellent thermal stability. The optimized NCPE-4 sample shows a high ionic conductivity of 1.1 × 10–3 S cm–1 at 30 °C, a sufficiently stable interface compatibility between the NCPE and electrode, and a higher electrochemical stability window of 4.8 V (vs Li/Li+). More interestingly, the assembled LiFePO4/NCPE-4/Li coin cell attains a discharge capacity of 149.1 mA h g–1 after 200 cycles at 0.5 C, and even at the high rate of 3 C, the capacity still stays over 83 mA h g–1. These results demonstrate that the novel NCPE-4 could be a promising candidate for the practical applications in lithium metal batteries.

The addition of stabilizers is indispensable method for improving the stability of PVC. In this work, a facile synthetic method of CeO 2 quantum dots (QDs) was used, for achieving the best dispersion and improvement of anti-UV properties, the surface of CeO 2 QDs was modified by ethyl 3,4-dihydroxybenzoate (EDHB), which was dispersed within the PVC matrix using the casting method to investigate the anti-UV and thermal properties. X-ray powder diffraction spectra (XRD), infrared spectroscopy (FT-IR), high resolution transmission electron microscopy (HRTEM), UV spectrophotometry and thermogravimetric analysis (TGA) were applied to characterize the structures, morphologies, and properties. The results highlighted that EDHB/CeO 2 can help reduce damages of PVC upon exposure to ultraviolet (UV) light and heat.

Radiation dosimeters displaying conspicuous response of irradiance are highly desirable, owing to the growing demand of monitoring high-energy radiation and environmental exposure. Herein, we present a case of dosimetry based on a discrete nanocluster, [Th 6 (OH) 4 (O) 4 (H 2 O) 6 ](TPC) 8 (HCOO) 4 ∙4DMF∙H 2 O (Th-SINAP-100), by judiciously incorporating heavy Th 6 polynuclear centers as radiation attenuator and organic linkers as photo-responsive sensor. Interestingly, dual-module photochromic transitions upon multiple external stimuli including UV, β-ray, and γ-ray are integrated into this single material. The striking color change, and more significantly, the visible color transition of luminescence in response to accumulating radiation dose allow an on-site quantitative platform for naked-eye detection of ionization radiations over a broad range (1–80 kGy). Single crystal X-ray diffraction and density functional theory calculations reveal that the dual-module photochromism can be attributed to the π(TPC) → π*(TPC) intermolecular charge transfer driven by enhanced π-π stacking interaction between the adjacent TPC moieties upon irradiation.

Advanced fluorescent materials have demonstrated great value in the anti-counterfeiting field for information storage and hiding. In this work, a novel strategy for producing UV light-switchable fluorescent patterns to hide and store information is proposed based on carbon dots (CDs) and Y2O3:Eu composites with exceptional optical properties. CDs can present blue emission under both 254 nm and 365 nm UV light excitation, but Y2O3:Eu can only arouse a red color under 254 nm light excitation. Under conventional 365 nm excitation, a single blue color and partial information are shown, however, the whole information in patterns can be displayed under specific 254 nm excitation. The functional anti-counterfeiting patterns are made by screen printing using as-prepared polyvinyl alcohol (PVA)-medium fluorescent inks. Moreover, the hidden information retained its integrity after printed patterns were exposed to an ambient environment for 90 days. Such invisible, tunable and ultra-stable fluorescent patterns utilizing 254 nm UV light well achieve information hiding and storage and increase information security for anti-counterfeiting applications.

Superhydrophobic coatings that are also self-healing have drawn much attention in recent years for improved durability in practical applications. Typically, the release of the self-healing agents is triggered by temperature and moisture change. In this study, UV-responsive microcapsules are successfully synthesized by Pickering emulsion polymerization using titania (TiO 2 ) and silica (SiO 2 ) nanoparticles as the Pickering agents to fabricate all-water-based self-repairing, superhydrophobic coatings. These coatings are environmentally friendly and can be readily coated on various substrates. Compared to conventional superhydrophobic coatings, these coatings can regenerate superhydrophobicity and self-cleaning ability under UV light, mimicking the outdoor environment, after they are mechanically damaged or contaminated with organics. They can maintain the superhydrophobicity after multiple cycles of accelerated weathering tests.

With the rapid advances in metal halide perovskite optoelectronics, eliminating toxic lead from perovskites has been an urgent demand. However, state-of-the-art lead-free perovskite photodetectors are still challenged with issues of low photoresponse, poor stability, etc. Here, all-inorganic lead-free perovskite (Cs3Cu2I5) single crystals that possess good stability under air exposure are synthesized via a facile solid reaction method. Meanwhile, a higher photoluminescence quantum yield of 95.2% and a prolonged carrier lifetime of 1.127 μs are obtained by further optimizing the synthesis. Benefiting from the polyporous surface and hollow structure of Cu-7,7,8,8-tetracyanoquinodimethane (CuTCNQ) microtubes, more Cs3Cu2I5 nanocrystals can adhere on the innershell and outershell of CuTCNQ-15 microtubes. This unique structure contributes to the improved efficiency of utilizing incident light and promotes charge carrier generation and transportation. As a result, the hierarchical CuTCNQ/Cs3Cu2I5 (hollow microtube/nanocrystal) heterostructure phototransistor exhibits a high responsivity of 88.36 A W–1 and a large detectivity of 1.66 × 1012Jones. The proposed lead-free perovskites and mixed-dimensional heterojunctions are promising for sensitive light detection.

Cyanurate motifs are emerging functional basic blocks (FBBs) for nonlinear optical (NLO) materials and birefringent materials. Herein, we report two new potassium lead(II) hydroisocyanurates, namely, K2Pb(H2C3N3O3)4(H2O)4 (I) and K3Pb(H2C3N3O3)5(H2O)6 (II). I and II belong to acentric Cm and centric C2/m, respectively. Compound I features a novel 3D network formed by 2D [K2PbO8(H2O)4]12− anionic layers interconnected by (H2C3N3O3)− anions. The 2D [K2PbO8(H2O)4]12− anionic layer is composed of 1D chains of edge-sharing K(1)O6 and K(2)O8 being further interconnected by 8-coordinated Pb2+ ions. Compound II exhibits a characteristic 3D framework based on 2D [K3PbO11(H2O)6]17− anionic layers interlinked through (H2C3N3O3)− groups, and the 2D [K3PbO11(H2O)6]17− anionic layer is based on K–O/H2O chains bridged by Pb2+ ions. Powder second harmonic generation (SHG) measurements of I revealed a moderate SHG response of approximately 2.6 × KDP with a type I phase-matching behavior under 1064 nm laser radiation. Theoretical calculations of I and II revealed their birefringence to be 0.325 and 0.193@532 nm, respectively. Their impressive optical properties mainly stem from stereochemically active lone pair (SCALP) Pb2+ cations and the planar π-conjugated (H2C3N3O3)− groups.
