The synthesized CuFe 2 O 4 exhibited enhanced enzyme-loading capacity while the established aptamer system could preserve enzymatic activity. As a result, the ascorbic acid generated by enzymatic hydrolysis effectively accelerated the decolorization of methylene blue in the colorimetric mode, as well as quenched the luminescence of luminol in the ECL mode. The samples could be rapidly screened through visual assessment in the colorimetric mode, and be further quantified by dual-mode detection. The linear detection ranges for the colorimetric and ECL modes were determined to be 1.0 pM ∼1.0 μM and 1.0 fM ∼1.0 nM, with corresponding detection limits of 0.7 pM and 0.1 fM, respectively. This dual-mode aptasensor platform enabled both qualitative and quantitative analysis. Significantly, it could dramatically improve detection efficiency and reduce operational costs. Furthermore, the proposed strategy demonstrated exceptional selectivity and stability. Consequently, this detection method was successfully applied to detect malathion residues in environmental as well as agricultural products, and demonstrated substantial potential for practical applications.","PeriodicalId":17364,"journal":{"name":"Journal of The Electrochemical Society","volume":"172 7","pages":"077513-077513"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147918328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effects of coating content on Li + diffusion kinetics remain insufficiently understood, limiting the full utilization of the reversible capacity of cathode active materials. In this study, a model system, zirconia-coated LiNi 0.83 Mn 0.05 Co 0.12 O 2 (NMC), is used to investigate the effect of coating content on the Li + diffusion kinetics. We used a wet-coating method to load the surface of the NMC cathode with varying amounts of Zr-O deposits (ZrO 2 and Li 2 ZrO 3 ). Electrochemical performance, including capacity, stability, and rate capability, exhibits a volcano-like trend with respect to coating content. This suggests that while Zr-O coatings can protect cathode particles, excessive coating increases cell internal resistance (IR) and polarization. The combined kinetics analyses using CV, GITT, and EIS reveal that polarization and cathode-electrolyte interphase (CEI) impedance are dependent on coating content, with high coating content impeding Li + diffusion across the interface. These electrochemical insights rationalize the optimization of coating content for NMC cathode materials, i.e., finding optimal balance between surface stability and Li + diffusion kinetics is key to improving the reversibility of the cathode active material. Specifically, for the model system in our study, a 1.5 wt% Zr coating achieves the best overall electrochemical performance.","PeriodicalId":17364,"journal":{"name":"Journal of The Electrochemical Society","volume":"172 6","pages":"060517-060517"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147920975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
