Environmentally sustainable, non-toxic, and harmless multifunctional cotton fabrics, which are endowed with antioxidant and UV-resistant properties, exhibit considerable potential for applications in food protection and packaging. Consequently, there is an imperative need for the advancement of novel coating systems that can endow cotton fabrics with supplementary functional properties. Bamboo ethanol lignin (EL) was synthesized using a clean ethanol pulping process, and a multifunctional coating of EL was fabricated through a one-pot dipping method. In brief, EL interacts with cotton fibers via hydrogen bonding and physical adhesion, and the optimized sample, designated as Cotton@EL 1 , demonstrates outstanding antioxidant and UV-blocking properties. Compared to EL 0 , EL 1 exhibited a substantially higher antioxidant efficiency of 80.3 % and effectively blocked both UVA (99.99 %) and UVB (100 %) radiation. Furthermore, Cotton@EL 1 exhibited a UPF value of 48.2, with UV transmittance below 3 %, showcasing exceptional UV protection performance. In conclusion, this study presents a novel approach for the utilization of high-value wood materials in the development of environmentally sustainable, non-toxic, and multifunctional food protection and packaging fabrics.

Silk fiber, as a luxurious textile raw material, is widely used in the textile industry due to its excellent mechanical properties and wearing comfort. However, the poor (ultraviolet, UV) light stability of silk affects its further application in high-end textiles, fashionable apparel, and smart materials. Although surface modification can endow the excellent UV resistance of silk fibers, it often reduces its comfort property. Herein, a laminated ultrathin Al2O3/TiO2 coating with a total thickness of 120 nm is fabricated on the surface of silk fiber via a modified atomic layer deposition (ALD) technique. The tenacity of ALD-coated silk can maintain 61.1% of its original value after exposure to intense UV light (640 mW/cm2) under high temperature (>200 °C) for 6 h, which is far superior to other work that has been reported. This can be attributed to the synergistic effect of the reflection of UV light by the multilayer film barrier, the strong oxidizing free radicals by the Al2O3 layer in the innermost layer, and thermal shield of laminated ultrathin Al2O3/TiO2 film. ALD-coated silk fabrics can also demonstrate a multicycle laundering durability, thermal and chemical stabilities, and flame retardancy. More importantly, the wearing comfort of the modified silk has no obvious change. This method provides principle and technical guidance in high-performance and multifunctional fibers and devices.

The hydrophobic surface of extruded polystyrene foams (XPSF) was modified by UV curable adhesives to enhance the interfacial bonding strength (BS) with mortar. The UV adhesive contained epoxy acrylate resin, acrylic acid and butyl acrylate (denoted as EAB). After EAB modification, the BS value in dry state (BS-D) increased from 0.050 MPa of unmodified XPSF with mortar to 0.210 MPa. Then, 3-aminopropyltriethoxysilane (APTES) was further introduced into EAB to form the water-resistant coatings (denoted as EABT) to enhance the BS value in wet state (BS-W). By optimizing the composition, the maximum BS-D and BS-W of 0.216 and 0.158 MPa in 7-day curing were obtained. The bonding mechanism illustrated that the modified XPSF was chemically bonded with mortar.

N-Halamine-based antibacterial materials are widely used due to their excellent characteristics. However, the N–Cl bonds in N-halamine-based materials are not stable under UV light irradiation so that they are difficult to recover and reuse. Here, a kind of N-halamine-immobilized Fe3O4@SiO2@TiO2(F@S@T-Cl) nanoparticles were prepared. In addition, the UV stability and regeneration capacity were also studied after variable time exposure to UV light. The results showed that nanoparticles have great antibacterial properties against Staphylococcus aureus and Escherichia coli. Meanwhile, the N–Cl bond in the nanocomposite showed outstanding storage stability under UV light irradiation and good regeneration ability; the material can realize cyclic utilization and solve the problem of secondary pollution of the antibacterial material. It provides a broader application prospect for the recyclable N-halamine antibacterial material.

Hydrogels have drawn intensive attention as emerging materials for various applications in wearable sensors, soft robotics, and implantable devices. However, fabricating hydrogels with UV-shielding and antioxidant properties still remains a challenge. Herein, we prepared biocompatible 3-allyloxy-2-hydroxypropyl-lignin/polyacrylic acid (AHP-lignin/PAA) hydrogels with self-adhesion, conductivity, UV shielding, and antioxidant activity as wearable sensors by the incorporation of lignin into PAA. The structure, lap shear strength, and biocompatibility were characterized using the UV–vis spectrometer, universal testing machine, and cell test. The hydrogels showed strong adhesion to various substrates. The AHP-lignin/PAA hydrogels had excellent UV shielding and free radical scavenging capacity. Meanwhile, AHP-lignin/PAA hydrogels exhibited excellent sensitivity to tiny changes in low pressure. Notably, the hydrogels could adhere to the skin well without any other adhesives to monitor the movement signals of the body motion accurately. The biocompatible AHP-lignin/PAA hydrogels with self-adhesion, conductivity, UV shielding, and antioxidant activity offer great potential applications in wearable sensors.

In this study, nano-nickel ferrite (NiFe2O4) was successfully prepared by hydrothermal synthesis and applied to the oxidative removal of chlortetracycline hydrochloride (CTH) in the presence of ultraviolet radiation (UV) and peroxymonosulfate (PMS). Several characterization methods were used to reveal the morphology and surface properties of nano-NiFe2O4, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared absorption (FTIR) spectroscopy. The removal efficiency of CTH, the factors affecting the reaction process and the reaction mechanism of PMS activated by UV combined with nano-NiFe2O4 (UV + nano-NiFe2O4/PMS) in aqueous solution were systematically studied. The results showed that the UV + nano-NiFe2O4/PMS system led to a higher removal efficiency of CTH than other parallel systems. The results also showed that the CTH removal efficiency was enhanced under optimal conditions ([nano-NiFe2O4] = 1 g L−1, [PMS] = 1 g L−1, [UV wavelength] = 254 nm and [pH] = 11) and that a removal efficiency of 96.98% could be achieved after 60 min. In addition, the influence of the PMS concentration, CTH concentration, dosage of added nano-NiFe2O4 and pH on the PMS activation efficiency and CTH oxidative degradation effect was studied. Inorganic anions such as Cl−, HCO3−, CO32− and NO3− increased the removal efficiency of CTH by 21.29%, 27.17%, 25.32% and 5.96% respectively, while H2PO4− inhibited CTH removal, and the removal efficiency of CTH decreased 6.08% after 60 min. Free radical identification tests detected SO4−˙, OH˙ and 1O2 and showed that these species participated in the degradation reaction of CTH. The results of LC-MS and TOC analysis showed that CTH was degraded in the UV + nano-NiFe2O4/PMS system through hydroxylation, demethylation, deamination, and dehydration reaction and finally mineralized into CO2. These findings confirmed that nano-NiFe2O4 is a green and efficient heterogeneous catalyst for activation of PMS and demonstrates potential applicability in the treatment of antibiotic wastewater.

Recently, the heterogeneous advanced reduction processes (ARPs) for bromate (BrO 3 - ) degradation have attracted considerable attention due to its stable performance and easy combination with UV disinfection. In this study, a UV/TiO 2 -Bi advanced reduction process (ARP) was established for BrO 3 - removal without adding external sacrificial agents. In the UV/TiO 2 -Bi ARP, Bi nanoparticles (NPs) doped on the TiO 2 acted as hole trapping centers, while TiO 2 NPs were used as reduction centers for the reduction of BrO 3 - , which enhanced the charge carrier separation. The UV/TiO 2 -Bi-1% ARP exhibited the highest BrO 3 - removal rate without the addition of sacrificial agents in the reaction solution compared to UV/TiO 2 ARP and the UV/TiO 2 -Bi ARP at other Bi/Ti ratios. The result of 72% removal of 200 µg/L BrO 3 - at 60 min by 0.2 g/L TiO 2 -Bi-1% in tap water at pH 6.8 and 7.71 mg/L dissolved oxygen (DO) demonstrates the promising potential of the UV/TiO 2 -Bi ARP for the removal of BrO 3 - in practical applications. Compared to the 99.5% removal in deionized (DI) water at 60 min, lower BrO 3 - reduction in tap water was likely attributed to the consumption of photo-generated electrons by NO 3 – and the adsorption of natural organic matter on the surface of TiO 2 -Bi-1% nanocomposites. The study provides not only a novel BrO 3 - removal system with good photo-reduction performance, but also some guidance for the influence of constituents in raw water on the treatment of BrO 3 - .

In this work, we present a targeted design strategy that combines Group IIIA metal cation and fluorine anion to simultaneously enhance the band gap and birefringence in selenite-based system. Three new ultraviolet (UV) transparent selenite fluorides, SrAl(SeO3)F3 (1), BaAl(SeO3)F3(H2O)0.25 (2), and ZnGa(SeO3)2F (3), were successfully synthesized under mild hydrothermal conditions. Remarkably, all three compounds exhibit wide band gaps as well as large birefringence. In particular, ZnGa(SeO3)2F (3) demonstrates a pronounced birefringence value of 0.176 at 546 nm, representing the highest birefringence reported among all known selenites with a band gap above 5.0 eV. Theoretical investigations indicate that the strong optical anisotropy is predominantly attributed to the stereochemically active lone-pair electrons of Se(IV) cations. The [Zn2O8] dimers and the infinite [GaO4F]∞ chains in ZnGa(SeO3)2F (3) crucially facilitate the optimal spatial arrangement of [SeO3] groups. This study expands the structural diversity of selenite fluorides and provides an effective pathway for designing high-performance birefringent crystals suitable for UV applications.

The poor interfacial adhesion and limited durability of conventional cellulose-based superhydrophobic coatings hinder their practical applications. Herein, we report a robust and universal superhydrophobic coating fabricated from hemp stalk-derived micro-nano cellulose (MNC) via a rapid UV-curing strategy. The MNC was strategically modified to create vinyl-functionalized filler (MMNC), which forms a covalently cross-linked micro-nano network with an epoxy vinyl resin under 30 s of UV irradiation. The resulting coating exhibits a water contact angle (WCA) of 155.7° and demonstrates exceptional durability, maintaining superhydrophobicity (WCA > 150°) after severe tests including sandpaper abrasion, prolonged exposure to extreme pH (1−13) environments, UV irradiation for 288 h, and 30,000 stretching cycles (up to 200 % strain). Multifunctional applications are showcased, such as self-cleaning and anti-icing on glass (delaying freezing time to 470 s), efficient oil-water separation on filter paper, and significantly enhanced corrosion resistance on steel, with an electrochemical impedance modulus three orders of magnitude higher than that of the pure resin after 50 d in salt spray. This work provides a scalable, energy-efficient, and biomass-based platform for high-performance protective coatings.

Host-guest systems of carbon dots (CDs) embedding in matrix with room-temperature afterglow (RTA) are of great importance for various applications, but so far rather limited due to relaying on high-energy ultraviolet (UV) excitation, monochromatic afterglow emission, or harsh synthesis. Herein, PTA materials (PASP@BA) with UV/visible light dual-mode excitation are prepared via one-step heat treatment of polyaspartic acid (PASP) and boric acid (BA). The RTA colors of PASP@BA display a significant bathochromic shift from blue to yellow as the excitation wavelength increases from 254 to 420 nm under ambient condition. Impressively, the visible-light-activated ultralong RTA can last for about 7 s by naked eye under ambient conditions. By correlating photophysical properties with structural characterization results, it is concluded that the polycrystalline boron oxide matrix and covalent B–C bonds can effectively suppress non-radiative transitions and stabilize the triplet excited state of CDs by restricting molecular motion and isolating environmental quenchers, thus facilitating the generation of long afterglow. More interestingly, the afterglow color can be also tuned by dynamic varying in B–C bond density and CDs dimensions. Finally, practical applications of such photo-responsive systems in multi-level information anti-counterfeiting and encryption are further demonstrated.

A new noncentrosymmetric borate CsZn2B3O7 was synthesized by the solid-state reaction techniques. The crystals were obtained by flux method and are of block shape without layering tendency. Single-crystal X-ray diffraction analysis reveals that the crystal structure is composed of [Zn2BO5]∞ two-dimensional layers that are bridged by [B3O6]3– groups to form a three-dimensional framework with one-dimensional channels occupied by Cs+ cations along the a and c axes. Thermal analysis indicates that CsZn2B3O7 melts incongruently. UV–visible–near-IR diffuse reflectance spectrum gives a short absorption edge at 218 nm. CsZn2B3O7 is phase-matchable, with a powder second-harmonic generation (SHG) efficiency of 1.5 × KDP (KDP, potassium dihydrogen phosphate) at 1064 nm, based on the Kurtz–Perry method. These results show that CsZn2B3O7 may have prospects as a UV nonlinear optical material. Interestingly, the SHG efficiency of CsZn2B3O7 is about twice that of γ-KBe2B3O7, a structurally analogous alkaline and alkaline earth borate. First-principles calculations combined with atom-cutting analysis reveal that the ZnO4 tetrhedral groups in CsZn2B3O7 account for the SHG enhancement.

A series of fluorine-silicon block urethane acrylates (PSi-FMPG-IPDI-HEMA) were synthesized from hydroxypropyl-terminated polysiloxane (PSi), newly-prepared fluorodiol (FMPG), isophorone diisocyanate (IPDI) and hydroxyethyl methacrylate (HEMA). Their molecular structures were characterized by Fourier transform infrared and gel permeation chromatography. The compatibility of the oligomers with HFMA was validated using UV–vis transmittance analysis. The thermal stability, water and chemical resistance, contact angles and anti-adhesive performance of the films were measured. It was found all the films had good thermal properties, and excellent water and chemical resistance. The FMPG content affected the surface energy and anti-adhesive performance of the films. The films with more FMPG presented lower surface energy, lower peel strength, and higher residual adhesion. More importantly, the release films designed based on the fluorine-silicon block urethane acrylates had tremendous application potential.
