Its dietary intake is associated with health risks, and developing highly selective detection methods is of great significance. In order to address the issue of poor selectivity of existing Lut sensors, this study constructed an electrochemical biosensor. The sensor was fabricated by modifying a glassy carbon electrode (GCE) with MWCNTs, UiO-66-NH₂ (MOF), AuNPs and laccase (Lac). By taking advantage of the high conductivity of multi-walled carbon nanotubes, the large specific surface area and enrichment effect of UiO-66-NH₂, the biocompatibility and electron transfer ability of AuNPs, as well as the biological catalytic specificity of Lac, significant performance synergy was achieved. The catalytic activity of Lac on Lut was studied by UV–vis, and the materials were characterized by electron microscopy, Fourier-transform infrared, and X-ray methods, respectively. The square wave voltammetry study demonstrated that this electrochemical sensor exhibited an excellent detection performance for Lut, with a linear detection range of 0.02–10 μM and a detection limit as low as 7.59 nM. In the actual samples (thyme, parsley, oregano) tests, the results were highly consistent with HPLC. The recovery rates after adding standards were ideal, fully demonstrating the excellent practical application potential.","PeriodicalId":17364,"journal":{"name":"Journal of The Electrochemical Society","volume":"173 3","pages":"035502-035502"},"PeriodicalIF":0.0,"publicationDate":"2026-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381659","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}

Results from cyclic voltammetry demonstrate that cathodic reduction of CO 3 2− constitutes a diffusion-controlled irreversible process.

The Fe-Ni alloy anode exhibits exceptional stability in molten salt, forming a protective Fe 2 O 3 -NiFe 2 O 4 composite oxide layer during electrolysis that effectively safeguards the substrate. During anodic reactions, O 2− discharge precedes CO 3 2− oxidation, governed by O 2− concentration gradients and diffusion kinetics within the molten salt, causing O 2 concentration in the anode gas to increase with temperature until peaking at 83% at 880 °C before declining markedly above 900 °C.","PeriodicalId":17364,"journal":{"name":"Journal of The Electrochemical Society","volume":"172 8","pages":"082504-082504"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://iopscience.iop.org/article/10.1149/1945-7111/adfb33/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A combination of cyclic voltammetry (CV), square wave voltammetry (SWV), and reverse chronopotentiometry (RCP) was employed to elucidate the underlying electrochemical mechanisms. The diffusion coefficients of Lu(III) ions were determined from chronopotentiometry (CP) measurements. Lu-Ga intermetallic compounds were formed via the co-deposition of Lu(III) and Ga(III) on an inert electrode. Thermodynamic properties, including equilibrium potential and Gibbs free energy change of formation, were evaluated using open-circuit potential (OCP) measurements. Additionally, linear polarization (LP) analysis was performed to investigate the kinetics of the Lu(III)/Lu reduction on Mo and liquid Ga electrodes, yielding exchange current densities and charge transfer resistance at various temperatures. Furthermore, constant potential electrolysis (CPE) at different potentials (−1.4 V, −1.6 V, −1.7 V on liquid Ga and −1.9 V on Mo) for 15 h enabled the recovery of Lu(III) from the molten salt. Metallic Lu and Ga 3 Lu formed on Mo and liquid Ga electrodes respectively. The formed metallic Lu and Ga 3 Lu were characterized by XRD. Lu extraction rates reached 95.59% on Mo and 98.99% on liquid Ga, showing the latter’s higher efficiency.","PeriodicalId":17364,"journal":{"name":"Journal of The Electrochemical Society","volume":"172 7","pages":"072506-072506"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333500","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}

Prenatal, perinatal, and postnatal parameters were recorded, and demographic information was collected. Comparative analysis between the group of neonates exposed to antenatal MgSO<inf>4</inf> and the control group was performed.Results: A total of 98 patients were enrolled in the study, 49 of them were exposed to antenatal MgSO<inf>4</inf> for neuroprotection. The serum magnesium levels in the 5 first days of life were higher in the case group, and higher than the normal range of serum magnesium levels (>2.4 mg/dL), with a statistical significance. The number of days needed to normalize serum magnesium levels was higher in the case group compared to the control group (median of 7 days [1-8] versus 2 days [1-5]).Conclusions: Our findings show that antenatal administration of MgSO<inf>4</inf> is associated with high serum magnesium levels in neonates.

Additionally, the effect of water in the DES on the dissolution of ZnO and its electrochemical and spectroscopic behaviour was also studied. Solubility of ZnO in DES was found to be 95 g l-1 which decreased slightly to 85 g l-1 in the DES containing 10% water. Fourier transform infrared and Raman studies revealed that ZnO dissolved in DES by forming a [ZnCl3FA]- complex.

Feedback images and probe scan curves showed a heterogeneous passivation that was gently generated on the LiFePO 4 particles during both charging and discharging.

The composited cathode does not show obvious CEI formation within first two cycles. The SECM results between the pristine LiFePO 4 particles and the composited LiFePO 4 indicated the dynamic accumulation of CEI, which is influenced by the ability to charge transfer kinetics of cathode materials.
