In this study, the degradation of tartrazine (E102), a widely used anionic azo dye, was investigated by the Electro-Persulfate (EPS) process. The influence of the applied current intensity, persulfate concentration, and electrolysis time was systematically studied using kinetic analyses and then optimized using response surface methodology (RSM) based on a central composite design (CCD). The statistical model demonstrated excellent predictive power with a coefficient of determination R² = 94.37%. The identified optimal conditions were a current intensity of 337.4 mA, a persulfate concentration of 1.6 mM, and an electrolysis time of 21.5 min, achieving a maximum tartrazine removal efficiency of 98.01%. Density functional theory (DFT) calculations performed at the wB97XD/6–311 G(d,p) level in aqueous medium were used to elucidate the degradation mechanism at the molecular level. Analysis of frontier molecular orbitals, molecular electrostatic potential mapping, and Fukui function calculations identified N11, N12, and C20 as the preferential sites of radical attack. Three degradation pathways involving the cleavage of C-N bonds around the azo group have been proposed, leading to the progressive degradation of tartrazine into small molecules such as H₂SO₄, CO₂, H₂O, and N₂. The combination of experimental optimization and theoretical mechanistic study provides a comprehensive understanding of the EPS process and confirms its effectiveness as an innovative and sustainable solution for treating industrial effluents contaminated with dyes.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"21 8","pages":"Article 101454"},"PeriodicalIF":3.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148640998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the LiZn_0.05Mn_1.95O₄ (LZMO) sample, the LiZn_0.05Al_0.03Mn_1.92O₄ (LZMO-Al0.03) material via a low-temperature solid-state combustion synthesis route exhibited a well-defined truncated octahedral morphology with a narrowed particle size distribution. This specific structure effectively suppressed the Jahn-Teller distortion and enhanced structural stability during high-rate cycling. Consequently, the LZMO-Al0.03 sample delivered a high initial discharge capacity of 112.4 mAh·g⁻¹ and achieved an outstanding capacity retention of 66.0% after 2000 cycles at 20 C, confirming that appropriate Al³⁺ doping plays a crucial role in optimizing the electrochemical performance of the spinel cathode.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"21 8","pages":"Article 101456"},"PeriodicalIF":3.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148640996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their high hardness and limited room-temperature ductility pose significant challenges for conventional machining processes. Electrochemical machining (ECM), based on the principle of anodic dissolution, is not limited by the mechanical properties of the material, making it an effective method for achieving efficient and high-quality machining of γ-TiAl. However, during ECM in NaNO₃ electrolyte, the anodic dissolution of γ-TiAl generates a large number of insoluble electrolysis products. These products mix with the electrolyte to form a complex solid-liquid two-phase system, significantly altering the physical characteristics of the electrolyte, thereby affecting the electric and flow field distribution in the machining gap and reducing machining accuracy. Currently, quantitative research on the impact of γ-TiAl electrolysis products on the physical properties of the electrolyte is lacking. This paper proposes a method to characterize the content of these complex electrolysis products using equivalent electric charge concentration. The density, viscosity, and conductivity of the mixed solution of γ-TiAl electrolysis products and 10 wt% NaNO₃ solution were systematically measured under different product concentrations (0∼200 C/ml) and temperatures (0∼50°C). The results show that with increasing product concentration, the density of the mixed solution increases slightly (maximum deviation 2.06%), viscosity increases significantly (maximum increase ∼300%), and conductivity decreases (maximum decrease 7.36%). Under typical machining parameters, the decrease in conductivity leads to a reduction in the equilibrium gap of approximately 36.8 μm, which has a non-negligible impact on precision machining accuracy. Based on the experimental data, empirical formulas for the density, viscosity, and conductivity of the mixed solution as functions of temperature and product concentration were fitted using the least squares method, with correlation coefficients all above 0.985. This work provides key foundational data for the precise control and multi-physics coupling simulation of the γ-TiAl ECM process.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"21 8","pages":"Article 101449"},"PeriodicalIF":3.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148640994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a simple and cost-effective electrochemical immunosensor was developed for the detection of human epididymis protein 4 (HE4), an important ovarian cancer biomarker. The sensing platform was constructed using the 3-mercaptopropionic acid-capped cadmium telluride quantum dots (M-CdTe QDs) deposited onto a screen-printed carbon electrode (SPCE), followed by its modification with chitosan and glutaraldehyde for efficient antibody immobilization. The characterization of M-CdTe QDs confirmed the successful formation of nanosized crystalline CdTe quantum dots with favorable morphological and structural properties. Electrochemical characterization of the fabricated immunosensor was carried out using cyclic voltammetry and electrochemical impedance spectroscopy, which demonstrated enhanced electron transfer after incorporation of M-CdTe QDs and successful stepwise electrode modification. Under optimized experimental conditions, the developed immunosensor exhibited a wide linear detection range from 0.00001 to 1 nmol/L with a low detection limit of 0.00000952 nmol/L for HE4 detection. The immunosensor also showed excellent selectivity, reproducibility, repeatability, and storage stability. Furthermore, recovery studies in spiked serum samples demonstrated satisfactory analytical performance, with recovery values ranging from 93% to 94%. Validation using enzyme-linked immunosorbent assay (ELISA) confirmed the capability of the developed platform for sensitive HE4 detection. The proposed immunosensor presents strong potential for point-of-care applications in early ovarian cancer diagnosis and disease monitoring.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"21 8","pages":"Article 101453"},"PeriodicalIF":3.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148640995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
