In this work, a novel Ti/TiO 2 -NTA/meso-flower PbO 2 electrode (TMF-PbO 2 ) was developed by anodic oxidation and modified oxygen bubble-template electrodeposition. Characterization of the electrode confirmed that the meso-flower layer exhibited a unique 3D and hierarchical structure with a rough morphology. N 2 adsorption-desorption isotherms and cyclic voltammetry suggested that TMF-PbO 2 possessed a 2.18 times larger specific surface area and at least a 1.46 times larger electroactive area than the electrode with a porous PbO 2 layer. The investigation of the effect of the operation parameters indicated that the optimal conditions were a pH value of 3, supporting electrolyte concentration of 10.0 g L −1 and current density of 25 mA cm −2 . The electrochemical degradation of 1H-1,2,4-triazole (Tz) by TMF-PbO 2 was studied by HPLC and LC‒MS with the assistance of quantum chemical calculations. The TMF-PbO 2 achieved 100% removal of Tz and 70.4% removal of COD on the advanced treatment of actual pesticide tailwater with an energy consumption of 29.40 kWh kg −1 COD. The EC 50, 48 h value and BOD 5 /COD ratio of the treated wastewater were 70.6±5.9% and 0.64, respectively, indicating significantly low toxicity and high biodegradability. Cyclic testing also suggested that TMF-PbO 2 was stable during application. The excellent performance of TMF-PbO 2 in this study indicated that this kind of electrode is highly applicable for the treatment of pesticide tailwater.

Cobalt is emerging as the next-generation interconnect material to replace copper for integrated circuit sub-10 nm technology nodes. Due to its susceptibility to corrosion, identifying effective corrosion inhibitors for Co during the chemical mechanical polishing (CMP) is crucial. In this study, theoretical computations and experimental approaches were employed to investigate the corrosion inhibition effects of benzotriazole (BTA) and its derivatives—methylbenzotriazole (TTA) and 5-carboxybenzotriazole—on Co surfaces. Quantum chemical calculations and molecular dynamics simulations were used to reveal the corrosion mechanism at the atomic level. The computational findings were further validated by electrochemical experiments. Among the inhibitors studied, TTA exhibited the highest adsorption affinity for the Co surface, achieving an inhibition efficiency of up to 91.71 %. This is attributed to the formation of a dense protective layer on the Co surface through both physical adsorption via intermolecular forces and chemical adsorption via charge transfer. CMP experiments demonstrated that all three inhibitors significantly reduce the material removal rate (MRR) of Co. Notably, when the TTA concentration reaches 9 mM, the MRR is reduced to 132.64 nm/min, meeting the requirements for Co bulk polishing. These findings suggest that TTA is a highly promising Co corrosion inhibitor for slurry development in CMP processes.

Two novel zinc porphyrin dyes containing either benzotriazole or 2 H -[1,2,3]triazolo[4,5- c ]pyridine as auxiliary acceptors, respectively, were synthesized for dye-sensitized solar cells. These two auxiliary acceptors were firstly applied into porphyrin based dyes. The photophysical and electrochemical properties of the dyes were investigated. These two dyes show the whole visible light absorption when they are adsorbed on the TiO 2 film, which means that they are promising sensitizers for dye-sensitized solar cells. The absorption intensity of the triazolopyridine containing dye is higher than that of the benzotriazole containing dye, resulting in a better light harvesting. Thus, the dye-sensitized solar cell based on the former dye achieved higher conversion efficiency of 6.65% than the cell based on the latter dye (6.17%) with chenodeoxycholic acid as the coadsorbant.

Infectious diseases pose a major challenge to human health, and there is an urgent need to develop new antimicrobial agents with excellent antibacterial activity. A series of novel triazolo[4,3-a]pyrazine derivatives were synthesized and their structures were characterized using various techniques, such as melting point,1H and13C nuclear magnetic resonance spectroscopy, mass spectrometry, and elemental analysis. All the synthesized compounds were evaluated for in vitro antibacterial activity using the microbroth dilution method. Among all the tested compounds, some showed moderate to good antibacterial activities against both Gram-positiveStaphylococcus aureusand Gram-negativeEscherichia colistrains. In particular, compound2eexhibited superior antibacterial activities (MICs: 32 μg/mL againstStaphylococcus aureusand 16 μg/mL againstEscherichia coli), which was comparable to the first-line antibacterial agent ampicillin. In addition, the structure–activity relationship of the triazolo[4,3-a]pyrazine derivatives was preliminarily investigated.Keywords:nitrogen-containing heterocycles;triazole compounds;triazolo[4,3-a]pyrazine derivatives;antibacterial activity

A general one-step lateral flow immunochromatographic assay (LFIA) for the quantitative detection of triadimefon (TDF) and triadimenol (TDN) in fruit and vegetable samples was developed using time-resolved fluorescence microspheres (TRFM) as labels. A specific anti-triadimefon monoclonal antibody (mAb) was conjugated with TRFM to fabricate LFIA test strips. A time-resolved fluorometer as an LFIA reader was applied to obtain quantitative results and assess risk ranges for the LFIA test strips. Under the optimized experimental conditions, the limits of detection (LODs) in buffer/cucumbers/tomatoes/oranges were 0.046 ng/mL, 0.135 µg/kg, 1.047 µg/kg, and 5.811 µg/kg, respectively, which are ca . 1000 times lower than that of colloidal gold-labeled strips. The recovery in cucumber/tomato/orange samples was 109.4–116.7%, 87.7–110.9%, and 88.0–111.9%, respectively, indicating that the test strips had good reliability. Coupled with the easily customizable pretreatment procedures for various samples, the LFIA results were obtained within 18 min without the need for professional personnel or complicated equipment. TRFM-LFIA for TDF and TDN also shows remarkable specificity and precision. The test strips were also low-cost, portable, and convenient to use. These results indicate the test strips could be utilized as a novel strategy for on-site detection of TDF and TDN, which has the potential to expand and detect other pesticide or insecticide residues in food.

The accumulation of marine biological growth has irreversible negative effects on shipping and coastal fisheries. In this paper, a new antibacterial nanofiller—triazole fluoroaromatic hydrocarbon−modified nano−zinc oxide (ZnO−APTES−TRF)—was prepared by a Cu(I)−catalyzed azide–alkyne click chemical reaction. The modification of nano−ZnO with triazole ring fluoroaromatic hydrocarbons were testified by FT−IR, XPS, and EDS. The grafting rate of ZnO−APTES−TRF can reach 32.38%, which was verified by the TGA test. The ZnO−APTES−TRF was mixed with zinc acrylate resin to produce a low surface energy antifouling coating with a surface water contact angle of 106°. The bactericidal rate of ZnO−APTES−TRF againstEscherichia coli,Staphylococcus aureus, andPseudoalteromonassp. can reach more than 98% due to the synergistic effect of triazole and fluorine. The 120−day marine experiment shows that the low surface energy antifouling coating of ZnO−APTES−TRF/ZA is expected to be widely used in the field of marine antifouling.Keywords:antifouling;marine;ZnO;triazole;modification;hydrophobic

Material corrosion is a critical factor leading to structural failure, performance degradation, and significant economic losses, particularly in harsh marine environments. Therefore, enhancing the corrosion resistance of metallic materials is crucial for extending equipment service life, ensuring operational safety, and reducing maintenance costs. This work elucidates the passivation mechanism of 1,2,3-benzotriazole (BTA) on B30 cupronickel (Cu 30Ni alloy, UNS C71500) through integrated electrochemical analysis and 28-day artificial seawater immersion testing. XPS characterization revealed a multi-component passivation layer (20–30 nm thickness) comprising Cu(I)-BTA organometallic compounds, Ni(II)-BTA chelates, and crystalline Cu₂O domains. The optimized BTA treatment enhanced surface hydrophobicity, evidenced by a 20 % increase in water contact angle (85° → 102°). Electrochemical polarization demonstrated remarkable corrosion current density suppression from 18.5 μA/cm 2 (bare alloy) to 0.504 μA/cm 2 (passivated), indicating two-order-of-magnitude improvement. Long-term immersion tests at 25 °C showed 87 % reduction in corrosion rate (0.0114 → 0.0015 mm/a). The synergistic effects of organic-inorganic hybrid film formation and hydrophobicity enhancement establish BTA passivation as a viable eco-friendly alternative to chromate treatments for marine alloy protection.

In order to promote the green development of the nitration process of energy-containing materials and to reduce the environmental pollution and resource waste caused by the traditional nitration reaction. We used a solvent-free mechanochemical reaction to nitrify 3-amino-1,2,4-triazole and 3,5-diamino-1,2,4-triazole and successfully obtained 3-nitro-1,2,4-triazole and 3,5-dinitro-1,2,4-triazole by using sodium nitrite and molybdenum trioxide as catalysts. Several parameters affecting the nitration reaction were explored, and the structures of the products were analyzed by combining Gaussian, Multiwfn, and other computational software; also, single crystals of 3,5-dinitro-1,2,4-triazole sodium salt were cultivated and analyzed for their crystal structure and surface properties, and their copper and lead salts were obtained by reacting with metal salts. The present work provides a new idea for the development of green nitration of energy-containing materials.

A novel synthetic strategy to afford 1,2,3-triazole grafted chitosans via modified Wolff’s cyclocondensation was established. Subsequently, several multi-substituted 1,2,3-triazole grafted chitosans with a degree of conversion (DC) varying from 42.1% to 53.9% were synthesized and characterized. The chemical structures of the modified chitosans were confirmed by Fourier transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance spectroscopy ( 1 H NMR), and the DC of chitosan derivatives were determined by amino titration. Meanwhile, the impact of 1,2,3-triazole moieties in the chitosan on their thermal properties were characterized by thermogravimetic analysis (TGA) and differential calorimetry scanner (DSC) respectively.

An in situ preparation of multifunctional additives in water was firstly developed in this paper. The additives can be conveniently obtained by stirring anionic raw materials benzotriazole (BTAH) and cationic materials tetrabutyl ammonium hydroxide (N 4444 OH) or tetrabutyl phosphonium hydroxide (P 4444 OH) in water. The physicochemical and tribological properties of the obtained additives benzotriazole tetrabutylammonium (N 4444 BTA) and benzotriazole tetrabutylphosphonium (P 4444 BTA) were systematically studied. Compared with traditional water-based lubricant additives , they are simple to prepare, have excellent tribological properties and good solubilities in water. In addition to their excellent tribological properties, these additives also show significant corrosion resistant abilities, which make them multifunctional additives for water based lubricants.

Although considerable efforts have been devoted to novel ionic porous networks (IPNs), the development of them in a scalable manner to tackle the issues in pollutant treatment by adsorption remains an imminent challenge. Herein, inspired by natural spider webs, a knitting copolymerization strategy is proposed to construct analogue triazolium salt-based porous networks (IPN-CSUs). It is not only convenient to incorporate the cationic motifs into the network, but easy to control over the contents of ionic pairs. The as-prepared IPN-CSUs displays a high surface area of 924 m 2 g −1 , a large pore volume of 1.27 cm 3 g −1 and abundant ionic sites, thereby exhibiting fast adsorption rate and high adsorption capacity towards organic and inorganic pollutants. The kinetics and thermodynamics study reveal that the adsorption followed a pseudo-second-order kinetic model and Langmuir isotherm model correspondingly. Specifically, the maximum adsorption capacity of the IPN-CSUs is as high as 1.82 mg mg − 1 for permanganate ions and up to 0.54 mg mg −1 for methyl orange, which stands out among the previously reported porous adsorbents so far. It is expected that the strategy reported herein can be extended to the development of other potential efficient adsorbents in water purifications.
