Recently, tellurium (Te), a p-type semiconductor material, has attracted tremendous interest in electronics and large-scale integrated circuits owing to its high hole mobility and excellent air stability. Although evaporated Te thin films have shown great potential for large-scale p-type transistors, further research is needed to improve the quality of Te thin films and enhance their electrical performance. In this work, we demonstrate that a simple ultraviolet/ozone (UV-O 3 ) pretreatment of Si/SiO 2 substrates can significantly reduce surface roughness and improve crystallinity in TeO x /Te films, as confirmed by grazing-incidence X-ray diffraction (GIXRD), Raman spectroscopy and atomic force microscopy (AFM). The improved structural properties lead directly to a remarkable improvement in device electrical performance. The hole mobility of devices fabricated on UV-O 3 -pretreated substrates increases markedly from 27.4 cm 2 /V·s to 75.8 cm 2 /V·s compared with those on untreated substrates. In addition, the subthreshold swing, hysteresis, contact resistance, interface trap state density and threshold-voltage stability under both negative bias stress (NBS) and positive bias stress (PBS) are all substantially improved. This work provides a simple and easily implementable approach to enhance the electrical performance of p-type Te-based transistors, offering valuable guidance for their application in next-generation electronics.

Photocatalytic technology offers a promising solution for degrading organic pollutants in wastewater. However, catalysts often suffer from limited light absorption and rapid electron-hole recombination. To address the challenges, we developed a heterogeneous TiO 2 /CoAl-LDH catalyst for photocatalytic degradation of dyes such as Acid fuchsin (AF) and methyl orange (MO) and real wastewater under UV light irradiation. The aligned band structures of TiO 2 and LDH enhanced UV light energy absorption and electron-hole separation, resulting in superior photocatalytic activity. In treating real dyeing wastewater, TiO 2 /CoAl-LDH + H 2 O 2 + UV achieved higher decolorization than UV/H 2 O 2 or catalyst/H 2 O 2 alone under the same operating conditions. The process within the early stage (0–45 min) followed pseudo-first-order kinetics (kₐₚₚ ≈ 1.50 × 10 −2 min −1 ), with a clear H 2 O 2 optimum at 40.8 mM. Excitation–emission matrix (EEM) fluorescence showed rapid quenching of protein-like (B/T) and humic/fulvic-like (A/M/C) peaks with blue-shifts under the TiO 2 /CoAl-LDH + H 2 O 2 + UV condition corroborating deeper oxidation and mirroring the ADMI decolorization trend (fast loss of B/T within 15 min, followed by progressive depletion of humic-like emission). This study presents a simple and cost-effective method for developing efficient hierarchical semiconductor materials potentially applicable as photocatalysts for wastewater treatment.

In the fields of industrial manufacturing, biomedical diagnostics, and environmental monitoring, computing systems with von Neumann architecture suffer from inefficiencies due to the separation of UV sensing, memory, and processing, leading to increased complexity and hardware overhead. In-sensor computing utilizing UV-responsive optoelectronic neuromorphic devices offers a promising alternative by bypassing these limitations for efficient, low-power UV information processing. Here, we present a UV-responsive optoelectronic synapse based on a GaO x /ZnMgO quantum dots (QDs) heterojunction. This device selectively detects UV light and intrinsically suppresses noise, enabling integrated clear perception and fast computation. Various biological synaptic behaviors are demonstrated on the device under 300 nm UV illumination, including short-term memory (STM) to long-term memory (LTM) transition, learning–forgetting–relearning cycles, and dark adaptation behaviors. Leveraging synaptic features, a UV-driven neuromorphic vision system built from the device achieved 97% recognition accuracy on handwritten digits even in the presence of RGB noise. These results highlight the potential of GaO x /ZnMgO QDs heterojunction synapses for robust, noise-resilient in-sensor computing and high-fidelity UV image processing.

In this study, a magnetic NiFe 2 O 4 /MWCNTs/BiOI composite were fabricated and applied for enhanced and sustainable photocatalytic degradation of doxycycline (DOX) under UV light irradiation. The as-synthesized material was characterized by a series of techniques and its photocatalytic property was assessed via a couple of batch tests. With the pH at 3.0 and NiFe 2 O 4 /MWCNTs/BiOI loading of 1.5 g L −1 , the DOX degradation (at 45 mg L −1 ) efficiency could achieve 92.18% with the reaction rate constant k of 0.0072 min −1 . The high mineralization of DOX suggests the strong oxidation of both the parent pollutant and the intermediary products in the ternary catalyst system. DRS spectra indicated that compared with BiOI , the introduction of NiFe 2 O 4 and MWCNTs reduces the band gap energy of the NiFe 2 O 4 /MWCNTs/BiOI. The quenching test illustrates that h + , OH and O 2 − all functioned in the developed photocatalytic system, where O 2 − and h + play the dominant roles in DOX degradation. The more efficient electron-h + separation and more oxidizing species induced by UV light resulted in the significant improvement of DOX abatement in the developed coupling system compared with that on either BiOI or NiFe 2 O 4 /MWCNTs. The magnetic property of NiFe 2 O 4 /MWCNTs/BiOI enables its easy separation of the solid catalyst from the reaction solution and the sustainable application in the photocatalysis . Based on the intermediates of DOX decomposition identified by UPLC-MS, the possible degradation routes were proposed accordingly.

In this work, a light-stimulated artificial synaptic transistor based on one-dimensional nanofibers of gallium-doped indium zinc oxides (IGZO) is demonstrated. The introduction of gallium into the nanofiber lattice can effectively alter the morphology and crystallinity, leading to a wider regulatory range of synaptic plasticity. The fabricated IGZO synaptic transistor with the optimal gallium concentration and low surface defects exhibits a superior photoresponsivity of 4300 A·W −1 and excellent photosensitivity, which can detect light signals as weak as 0.03 mW·cm −2 . In particular, the paired-pulse facilitation index reaches up to 252% with over 2 h of enhanced memory retention exhibiting the long-term potentiation. Furthermore, the simulated image contrast and image recognition accuracy based on the newly designed IGZO synaptic transistors are successfully enhanced. These remarkable behaviors of light-stimulated synapses utilizing low-cost electrospun nanofibers have potential for ultraweak light applications in future artificial systems. Graphical

The uses of inorganic metal oxide as ultraviolet (UV) absorbers have potential to increase the production of UV protection and can also overcome the disadvantages of organic molecules. In this article, we report an effective technique to fabricating polyvinyl chloride (PVC) films with well UV shielding efficiency. Surface modification of zinc oxide (ZnO) nanoparticles (NPs) with different silane coupling-agents were achieved, and through solution casting technique dispersed within the PVC matrix. Infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and UV spectrophotometer were applied to study the structures, dispersions, and optical properties. The results showed that the functionalized ZnO NPs could be well dispersed in PVC and endow the polymer composite films with significantly improved anti-UV capability. The facile processing and obtained properties of PVC composites have shown potential for low cost and environmentally sustainable applications in the UV protection field.

Benzotriazole ultraviolet stabilizers (BUVs) are widespread and bioaccumulative aquatic contaminants. However, their immunotoxicity and underlying molecular mechanisms remain largely unexplored. In this study, we measured the concentrations of ten BUVs in the East China Sea and selected UV-P for further study based on its highest detected concentration. Consequently, marine medaka ( Oryzias melastigma ) were exposed to an environmentally relevant concentration (3.5 μg/L) and two elevated concentrations (35 and 350 μg/L) of UV-P for 28 days. Immunological parameters, histopathological alterations, and transcriptomic profiles were examined at the end of exposure. Additionally, bacterial challenge tests using Pseudomonas fluorescens were performed to assess host resistance. The results revealed an initial increase in the levels of alkaline phosphatase, immunoglobulin M, C-reactive protein, and complement component 3, followed by a significant decrease with increasing UV-P concentration. Histopathological damage was observed in immune tissues, including the liver, intestine, kidney, and gills. Transcriptomic analysis indicated significant enrichment of differentially expressed genes in multiple immune-related pathways following UV-P exposure. The key pathways affected mainly included cytochrome P450-mediated metabolism and the complement and coagulation cascades. The 24-h post-infection assessment revealed dose-dependent increases in bacterial loads and mortality rates in UV-P-exposed fish. Collectively, these findings demonstrate that UV-P induces immunotoxicity and increases the risk of bacterial infection in marine medaka. This study highlights the potential ecological threats posed by BUVs and offers valuable insights into the immunotoxic mechanisms of these contaminants.

The inhibitory effects of nine ionic liquids (ILs) on the catalase activity were investigated using fluorescence, absorption ultraviolet-visible spectroscopy. The interactions of ILs and catalase on the molecular level were studied. The experimental results indicated that ILs could inhibit the catalase activity and their inhibitory abilities depended on their chemical structures. Fluorescence experiments showed that hydrogen bonding played an important role in the interaction process. The inhibitory abilities of ILs on catalase activity could be simply described by their hydrophobicity and hydrogen bonding abilities. Unexpected less inhibitory effects of trifluoromethanesulfonate (TfO−) might be ascribed to its larger size, which makes it difficult to go through the substrate channel of catalase to the active site.

The incorporation of lignin into waterborne polyurethane (WPU) networks for the preparation of high-performance, multifunctional protective coatings represents a highly attractive yet challenging research direction. This study employed a highly reactive soluble modified lignin (MOLA) as a polyol and incorporated it into the main chain of a WPU polymer network. A series of bio-based waterborne polyurethanes (CLWPU–CO x ) with tailored molecular architecture was synthesized and found to exhibit corrosion resistance, UV blocking, UV-aging resistance, self-cleaning behavior, weather resistance, biodegradability, and non-biotoxicity. The influence of MOLA content on the chemical structure and properties of CLWPU–CO x was systematically investigated, and quantitative structure–property relationships between the MOLA loading ratio and material properties were established. The results indicated that MOLA simultaneously served as both a chemical and physical crosslinking site, thereby regulating the microphase separation of WPU. The resulting uniform internal structure and high crosslinking density endowed CLWPU–CO x with excellent hydrophobicity, water vapor barrier properties, gas barrier properties, and long-term outdoor durability, confirming its considerable potential for marine anti-corrosion protective coating applications.

A bioactive and biodegradable packaging film was fabricated via a solvent-casting method using poly(vinyl alcohol) (PVA) reinforced with alkaline–peroxide treated brewers’ spent grain (BSG-M) and zinc oxide nanoparticles (ZnO-NPs). Alkaline–peroxide treatment was applied to BSG, which is reported to disrupt lignin–carbohydrate associations and promote microfibrillation, yielding a modified lignocellulosic filler containing residual proteins that dispersed uniformly within the PVA matrix, thereby enhancing the tensile performance and soil degradability of the composite films. The incorporation of an optimal ZnO loading (2–3 wt%) facilitated the formation of dense hydrogen-bond networks and increased the tortuosity of the diffusion path. Consequently, the composite films exhibited a UV-B blocking efficiency exceeding 96%, antibacterial inhibition rates up to ∼100% (depending on ZnO loading) against Escherichia coli and Staphylococcus aureus , and a moderate DPPH-radical scavenging activity (approximately 20%). Specifically, the PBZ-3 film (containing 3 wt% ZnO) significantly enhanced the preservation of strawberries during 8 days of storage at 4 °C. Compared with commercial polyethylene (PE) packaging, the PBZ-3 film minimized weight loss to 12.84% and provided superior vitamin C retention and improved visual quality, while maintaining the critical advantage of biodegradability. Furthermore, soil burial tests demonstrated a 54% mass loss within 30 days, confirming a favorable balance between functional performance and biodegradability. These results indicate that the PVA/BSG/ZnO ternary composite film is a promising biodegradable active packaging material with moisture-barrier, UV-shielding, antibacterial, and extract-based antioxidant functions for fresh produce.

Near-ultraviolet-excitable red phosphors with high thermal stability are desirable for phosphor-converted LED applications, including potential plant-lighting applications. Herein, Sm3+- and Eu3+-activated Na3YB8O15phosphors were synthesized by a high-temperature solid-state reaction. Among the investigated compositions, the optimal activator contents were identified asx= 0.02 for Na3YB8O15:xSm3+andy= 0.70 for Na3YB8O15:yEu3+, with concentration quenching in both series mainly governed by dipole–dipole interactions. In the Sm3+/Eu3+co-doped phosphors, the emission color shifted from orange-red toward red as the Eu3+content increased. At 433 K, the Sm3+-doped, Eu3+-doped, and Sm3+/Eu3+co-doped samples retained 119.7%, 93.4%, and 102.3% of their room-temperature integrated emission intensities, respectively. The high thermal stability may be attributed to the structural characteristics of the host, its wide optical band gap, and the temperature-dependent redistribution of Stark and phonon-assisted emission components. A phosphor-converted LED fabricated using Na3YB8O15:0.02Sm3+,0.01Eu3+and a commercial 400–405 nm, 5 W near-UV LED chip produced multiband emission that partially overlapped with the absorption bands of both chlorophylls and the PRand PFRforms of phytochrome. These results suggest that Sm3+/Eu3+-activated Na3YB8O15is a promising thermally robust, spectrum-adjustable red phosphor for LED applications.

The removal of ammonia nitrogen (NH4+-N) using advanced oxidation processes (AOPs) has garnered increasing attention in wastewater purification. However, the application of the UV-activated persulfate (PS) system for treating NH4+-N wastewater is limited by the low reaction rate between NH4+-N and the reactive species (·OH and SO4·−) generated in the system. In this study, common chloride ions (Cl−) were employed to enhance the removal of NH4+-N in the UV/PS process; when the system conditions were pH = 7, [PS]0= 10mM, [Cl−]0= 35 mM, 30 mg/L NH4+-N was completely degraded within 40 min. The total nitrogen removal rate was 75.50%, and the reaction rate constant increased from 0.0026 min−1to 0.0801 min−1. The introduction of Cl−led to the generation of reactive chlorine species (RCS) in the system that could efficiently oxidize NH4+-N over a wide pH range (3–9), and the RCS, which efficiently oxidized NH4+-N across a wide pH range (3–9). Quenching experiments confirmed that these RCS were gradually produced through the activation of Cl−by ·OH and SO4·−. The common anions present in water bodies had little impact on the degradation performance of NH4+-N in the UV/PS/Cl−system. Overall, the UV/PS/Cl−system proposed in this study offers an effective approach for the efficient removal of NH4+-N.
