In sustainable materials engineering, designing rational and ecologically compatible ultraviolet (UV) protective materials to improve the efficiency of light protection is a major challenge. Sodium lignosulfonate (SL), a renewable biomass derivative possessing inherent UV-blocking and antioxidant properties, has been utilized as a foundational component in this research. Through one-pot synthesis approach, a light-colored sodium lignosulfonate zinc oxide composite (ZnO@SL) was successfully fabricated. The effective incorporation of ZnO within the SL matrix through systematic experimental characterization, while the preservation of the hexagonal wurtzite crystalline structure was concurrently preserved. Superior broadband UV attenuation is observed in the nanocomposite compared to pristine ZnO and SL through UV–visible spectroscopy and in vitro SPF evaluation. Through the complementary mechanisms combining physical scattering and chemical absorption, the excellent photoprotection enhancement is achieved, particularly when integrated with chemical sunscreens octocrylene (Oct) and avobenzone (Avo). The SPF value increases from 8.9 to 98.41 at a 2 wt% composite loading. The preserved π-conjugated system and oxygen-rich functional groups in SL are identified to facilitates charge transfer interactions with organic UV filters. This innovative engineering strategy establishes ZnO@SL as a dual-functional additive for the development of high-performance bio-based photoprotective formulations, offering enhanced light protection while reduced environmental impact.

Fast UV-cured Polybutadiene films were prepared in 10 s by using mercaptan pentaerythritol tetra(3-mercaptopropionate) (PETMP) as the cross-linker and PETMP-treated nano-SiO 2 as the filler, achieving significant improvements in overall performance, which may be applied as insulating materials for flexible printed circuits. The dispersion of SiO 2 in the polymer matrix was improved after treatment by PETMP and served as a “hard core” in enhancing their hardness greatly and improving the tensile strength about 50% from 7.5 to 15.2 MPa; they still retain excellent flexibility, maintaining shapes without cracking and peeling while folding in half under squeezing. The thermal expansion coefficient decreased from 2.22 × 10 −4 /°C to 2.02 × 10 −4 /°C and the glass transition temperature rose from 47.50°C to 58.62°C; meanwhile, they exhibited higher decomposing temperatures and higher residues, indicating the stabilizing effect of nano fillers. The incorporation of SiO 2 decreased their dielectric constant from 3.12 to 2.94 while maintaining stable dielectric loss of less than 0.02. Moreover, the addition of pretreated SiO 2 also improved their resistance to pure and salt water. Nevertheless, the excessive addition of SiO 2 led to local aggregations and thus adversely affected their overall properties if its addition was above 8% as seen from SEM pictures.

Sulfate radical (SO 4 − ) based advanced oxidation processes are effective for the removal of antibiotics including sulfonamides from freshwater. However, few studies were focused on the degradation of sulfonamides in marine aquaculture water and seawater, as well as the impact of transformation products on seafood such as fishes. In this work, sulfamethoxazole (SMX) was treated with UV/persulfate (UV/PS) system in different water samples. Chloride ions (Cl − ) had an inhibitory effect possibly due to the consumption and mutual quenching of reactive radicals. A slight promotion by bromide ions (Br − ) was observed and should be related not only to the transformation of Br , but also to the properties of the SMX itself. Bicarbonate ions (HCO 3 – ) significantly inhibited degradation as it is a scavenger of SO 4 − and HO in UV/PS. Sulfate ions (SO 4 2− ) showed a negligible impact on SMX degradation. The active sites of SMX were calculated to be the N1 and C7 atoms of the isoxazole ring, as well as the C9, C13 and N3 atoms of the benzene ring. Seven organic transformation products were identified by LC-MS/MS. Bromate (BrO 3 − ) and chloromethane as the potential human carcinogens were not detected from the reaction system of UV/PS with SMX in marine aquaculture water and seawater. Preliminary analysis of toxicity by the EPI Suite model, absorbable organic halogen (AOX) analysis and growth inhibition of Chlorella vulgaris proved that the UV/PS process could be used as a new disinfection method and it is relatively safer than traditional UV/NaClO disinfection.

Aramid fabrics are widely used in bulletproof armor because of their excellent mechanical properties. Previous studies have shown that ultraviolet radiation has a negative effect on the mechanical properties of aramid yarn, so improving the mechanical properties and impact resistance of aramid fabrics under ultraviolet radiation has become a research focus. In this work, aramid fabric was modified with CuO and ZnO particles to improve its ballistic performance under ultraviolet radiation. The ballistic impact resistance response and microscopic failure mechanisms of aramid fabrics under ultraviolet radiation were analyzed in detail. Under ultraviolet radiation, the ballistic limit velocity ( v bl ) of the CuO/ZnO-modified aramid fabric was 185.1 % greater than that of a neat fabric with a similar areal density. The v bl of the single-layer modified fabric was 45.6 % greater than that of the two-layer neat fabrics. The decrease in the ballistic performance of the aramid fabric under ultraviolet radiation was attributed to surface damage caused by the fracture of the chemical structure of the fibers, which weakened the mechanical properties of the fabric. The numerical simulation results were highly consistent with the ballistic impact test results, and the error between the numerical simulation and experimental results was within 10 %. The effects of changes in the mechanical parameters of the fabrics on the protection mechanism and energy absorption structure during ballistic impact were investigated. The energy dissipation of the modified fabric was at least 147.7 % greater than that of the neat fabric, further explaining the significant improvement in the ballistic performance of CuO/ZnO-modified fabrics under ultraviolet radiation.

Here, the ZnO-NRs/poly(EDOT-Pyridine-EDOT) core/shell heterostructure nanoarrays was prepared by the electrochemical polymerization of D-A-D type monomer (the 3,4-ethylenedioxythiophene(EDOT, donor) endcapped trimer with the pyridine(acceptor) as internal unit) on ZnO-NRs. This core/shell heterostructure nanoarrays was combined with ZnO-NRs to form p-n heterojunction for UV photodetector by face to face clamping of the two electrodes (ZnO-NRs/poly(EDOT-Pyridine-EDOT) and ZnO-NRs). The current-voltage and current-time curves under bias voltages of 1–6 V were tested, and the photoresponses of heterojunctions and bias voltages to UV light irradiation were systematically studied. The results showed that the poly(EDOT-Pyridine-EDOT) (poly(BPE)) uniformly covered ZnO-NRs and formed a core-shell structure, which was beneficial to increase the contact area between ZnO-NRs and poly(BPE). The ZnO-NRs/poly(BPE) heterojunction effectively improved the response performance of the UV photodetector and exhibited the highest photoresponsivity under 5 V bias voltage. The responsivity (R), detectivity (D*) and external quantum efficiency (EQE) were 150.87 A/W, 2.18 × 10 12 Jones and 51,351.5 %, respectively.

Colloidal quantum dots (CQDs) are very promising nanomaterials for optoelectronics due to their tunable bandgap and quantum confinement effect. All-inorganic CsPbX3 (X = Br, Cl and I) perovskite nanocrystals (NCs) have attracted enormous interests owing to their promising and exciting applications in photovoltaic devices. In this paper, all-solution-processed UV-IR broadband trilayer photodetectors ITO/ZnO/PbS/CsPbBr3/Au and ITO/ZnO/CsPbBr3/PbS/Au with high performance were presented. The role of CsPbBr3 QDs layer as the carriers-extracting layer in the trilayer devices was discussed. As compared with bilayer device ITO/ZnO/PbS/Au, both the dark currents and photocurrents under illumination from trilayer photodetectors are enhanced, but the trilayer photodetector ITO/ZnO(80 nm)/PbS(150 nm)/CsPbBr3(50 nm)/Au showed a maximum specific detectivity (D*) of 8.3 × 1012 Jones with a responsivity (R) of 35 A W−1 under 1.6 mW cm−2 980 nm illumination. However, another trilayer photodetector ITO/ZnO(80 nm)/CsPbBr3(50 nm)/PbS(150 nm)/Au showed a maximum D* of 1.73 × 1012 Jones with a R of 5.31 A W−1 under 6.8 mW cm−2 405 nm illumination. Further, the underlying mechanism for the enhanced performance of trilayer photodetectors was discussed. Thus, this strategy of all-solution-processed heterojunction configuration paves a facile way for broadband photodetectors with high performance.

Benzophenone (BP)-type UV filters can cause structural changes of carrier protein in plasma. The binding process of five BP-type UV filters with bovine serum albumin (BSA) was investigated by multiple characterization methods, along with their structure-affinity relationship involving the structure of the five BP-type UV filters and their binding affinity for BSA. The BP-type UV filters investigated bound to BSA spontaneously, and altered conformation of BSA. The binding constants and number of binding sites between BP-type UV filters and BSA were 103–106 M−1 and 0.82–1.26, respectively. These BP-type UV filters and BSA interacted with the same binding forces and went through the similar binding process, suggesting that the benzophenone skeleton structure was primarily responsible for the BP-type UV filters and BSA binding, and changes in the structure of the BSA. The BP-type UV filters with hydroxyl substituent (BP-1 and BP-9) and non-polar molecules (BP-6) had a high affinity for binding BSA and had a greater impact on BSA conformation.

The recent trend of combining perovskite with other materials to enhance optoelectronic performance has garnered significant interest. In this paper, MAPb 0.9 Sn 0.1 I 3 and ZnO–MAPb 0.9 Sn 0.1 I 3 photodetector were prepared by frequency magnetron sputtering and sol–gel spin-coating method. Hybrid heterojunction photodetectors have more beneficial optoelectronic performance compared to MAPb 0.9 Sn 0.1 I 3 photodetector, due to the presence of built-in electric fields, which can suppress the recombination of electrons and holes. At 7 V bias conditions, the responsivities of MAPb 0.9 Sn 0.1 I 3 photodetector were 0.022 and 0.015 A/W, and the responsivities of ZnO–MAPb 0.9 Sn 0.1 I 3 photodetector were 0.39 and 0.99 A/W obtained under 350 and 850 nm illumination, respectively. The maximum external quantum efficiency reaches 144.47%, the detection rate was 5.53 × 10 11 Jones and the light to dark ratio was 2.95 × 10 3 of ZnO–MAPb 0.9 Sn 0.1 I 3 photodetector. This study provides a basis for the preparation of perovskite heterojunction photodetectors with high optoelectronic performance. High performance UV–vis–NIR photodetectors based on ZnO/organic–inorganic hybrid Sn–Pb hybrid perovskite heterojunction.

The pseudo-persistence of pharmaceutical and personal care products (PPCPs)in the aqueous environment may pose potential risks to human health and ecosystems. The UV disinfection in wastewater treatment plants is one of the essential processes before PPCPs enter the water environment, so it is crucial to elucidate the photolytic behavior and mechanism of PPCPs under UV radiation . In this work, carbamazepine (CBZ) and caffeine (CAF) were selected as typical pollutants to investigate the effect of water matrixes, humic acid , inorganic ions , and pH on the UV radiation performance. Hydroxyl radical (•OH) and singlet oxygen ( 1 O 2 ) were identified by quenching experiments and electron paramagnetic resonance (EPR) spectra as playing a dominant role in the degradation process. UPLC-TOF/MS was conducted to identify 13 and 14 possible intermediates of CBZ and CAF, respectively. Moreover, combining density functional theory (DFT) calculations (Frontier Molecular Orbital and Fukui index), hydroxylation , oxidation , and ring cleavage were proposed as the main degradation pathways of the contaminants, which occurred first at the C(7C), N(17 N) and O(18O) sites of CBZ and at the C(9C) site of CAF. The bio-acute toxicity experiment and the Ecological Structure-Activity Relationships (ECOSAR) program were performed to analyze and predict the toxicity of the intermediates of CBZ and CAF under UV radiation, respectively. The results showed that the acute toxicity of both solutions increased after UV radiation and followed with the combined toxicity. This work has great scientific value and practical environmental significance for evaluating the UV disinfection process and managing PPCPs in the aqueous environment.

Using uniform carbon nanospheres as sacrificial templates, gold nanoparticle-modified ZnO@ In 2 O 3 hollow nanospheres with controlled dimensions and porous architectures were successfully synthesized through water bath, hydrothermal and chemical reduction methods. Gas sensing evaluation revealed that the Au-decorated ZnO@ In 2 O 3 hollow nanostructures exhibited a dramatically amplified response up to 14.8 when exposed to 10 ppm formaldehyde analyte at room temperature. Furthermore, multifaceted performance benefits of Au-decorated ZnO@ In 2 O 3 over single-phase ZnO, Au-ZnO, ZnO@ In 2 O 3 heterojunction-based composites were observed, including excellent selectivity towards formaldehyde even in complex gas mixtures; tremendous sensitivity enhancement stemming from synergies between efficient gas diffusion through hollow heterojunction nanospheres and accelerated surface reactions at catalytically-active Au sites; and rapid, fully-reversible response/recovery time of 32 s and 42 s, respectively. In-depth investigations were conducted into the fundamental sensing mechanisms enabling formaldehyde detection using AC impedance spectroscopy, in situ diffuse reflectance Fourier transform infrared spectroscopy (DRIFTS), and density functional theory (DFT) computational modeling analyses.

A novel macromonomer containing fluorinated units (PHFBMA-GMA) was synthesized through a two-step procedure: firstly, hexafluoro-butyl methacrylate (HFBMA) was polymerized in the presence of functional chain transfer agent 3-mercaptopropionic acid (MPA) and then the carboxyl acid group terminated polymer was end-capped with glycidyl methacrylate (GMA). Chemical structures of PHFBMA-GMA were characterized by gel permeation chromatography, fourier transform infrared spectroscopy (FTIR), and 1 H nuclear magnetic resonance (NMR). Subsequently, PHFBMA-GMA was employed as reactive surface additives added into UV-cured polyacrylate to modify UV-curable coatings. It is convenient to control the tail length of the fluorinated segments in this study by adjusting the ratio of initiator and chain transfer agent. The influence of both the concentration and the molecular weight of PHFBMA-GMA on the surface properties of UV-cured films was investigated. With increasing both the concentration and the molecular weight of PHFBMA-GMA, the surface energy of the UV-cured films decreased. X-ray photoelectron spectroscopy was employed to characterize and quantify the surface composition and the results confirm the enrichment of fluorinate atoms on the surface. Moreover, the physical properties of UV-cured films, such as gel content, water absorption, pencil hardness, adhesion, chemical resistance, mechanical properties, optical transmittance, and thermal properties, were also investigated in detail. The novel macromonomer was economical but effective to modify the properties of the UV-curable coatings. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016 , 133 , 43116.

Crosslinked polymer electrolyte (CPE) and composite polymer electrolyte are two of the most promising polymer electrolyte (PE) systems for improving the resistance to Li dendrite growth, but the trade-off and agglomerated effects of these PEs hinder the development of safe Li metal battery (LMB). Herein, a new class of crosslinked composite polymer electrolyte (CCPE) with the combination of confined ionic liquid (IL) polymer network and homogeneously dispersed boron nitride nanosheet (BNNS) for LMB is reported. This UV-curable CCPE is formed on electrode via in-situ crosslinking of a precursor solution in a rapid and solvent-free step, and the assembly process of LMBs and interfacial contact/adhesion are maximum optimized. The critical point of this CCPE is that a facile channel for Li + transfer and a robust skeleton for confining IL and strengthening interface are simultaneously achieved via the introduction of network structure and 2D BNNS in PE. Consequently, the LiFePO 4 ǀLi batteries involving CCPE show a great improvement in the charge-discharge cycling stability and rate performance compared with those of the cells with pure CPE. This study offers an effective and facile strategy for fabricating dendrite-resistant CCPE with potential applicability in next-generation energy storage systems .
