Physicochemical characterisations confirmed uniform NiO deposition, enhancing electron transfer kinetics and active surface area. The modified electrode exhibited distinct oxidation peaks at 0.24 and 0.48 V for VC and PA, respectively, with corresponding peak currents of 6.40 and 8.23 μA. Differential pulse voltammetry demonstrated excellent linear detection ranges of 200–893 μM for VC and 1–4.46 μM for PA, with detection limits of 15.9 and 0.254 μM, respectively. Stability and reproducibility tests yielded relative standard deviations of ≤1.31% for VC and ≤1.60% for PA over eight successive measurements. Interference studies confirmed selectivity, with negligible effects from ions and sugars at 100- and 50-fold concentrations, respectively. These findings underscore the NiO/SPCE’s potential as a robust, sensitive, platform for pharmaceutical quality control and therapeutic monitoring applications.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":"13 7-8","pages":"429-441"},"PeriodicalIF":0.0,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147883356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The products were characterized by Fourier transform infrared spectrum (FTIR), nuclear magnetic resonance hydrogen spectrum (1H NMR), and nuclear magnetic resonance carbon spectrum (13C NMR). The corrosion inhibition effect of salt-free imidazoline inhibitors with different carbon chains was evaluated by the static weight loss method, the electrochemical method, and scanning electron microscope observation. The corrosion inhibition mechanism was analyzed by adsorption mode, and an energy-dispersive spectrometer was used to study the adsorption of corrosion inhibitors on the steel surface. Transmission electron microscope and dynamic light scattering were used to analyze the aggregation of surfactants. It was found that with the increase of the carbon chain, the corrosion inhibition efficiency of imidazoline increased first and then decreased, and the corrosion inhibitor aggregate increased. There are two explanations for the decrease of corrosion inhibition efficiency after the chain length is too long: when the carbon chain is too long, the bending of the carbon chain will lead to the adsorption layer of the surfactant on the steel surface is not close, and the adsorption capacity of the corrosion inhibitor on the surface of the steel sheet is weak when the carbon chain is too long. The long hydrophobic tail chain is entangled with each other, resulting in a larger aggregation of surfactant.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":"13 5-6","pages":"332-346"},"PeriodicalIF":0.0,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147900088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, only a small number of MOFs are capable of melting. In this paper, zeolitic imidazolate framework-8 (ZIF-8) nanoparticles (diameter of 100 nm) were practically produced and incorporated with a hydrophobic ionic liquid (IL) to develop a novel high-performance MOFs-based ZIF-8@IL nanolubricant additive. Then, reciprocating tribological experiments were conducted across a range of ZIF-8@IL concentrations addition in the 150 SN base oil. With respect to using the plain oil, the use of addition of ZIF-8@IL exhibits very good lubrication performance and the optimized case was achieved with the incorporation of a 4.0 wt.% ZIF-8@IL additive, resulting in a decrease of about 27% in coefficient of friction and 20% in the wear track width. The notable lubrication achievement is due to the collective effects of rolling, mending, polishing, and tribofilm formation. In addition, the use of ZIF-8@IL nanolubricant demonstrated an obvious inhibition of oxidational wear.
