Electrochemical polishing is widely used in metal surface finishing due to its low cost and high efficiency. To solve the problem of surface quality after WEDM machining, in this paper, electrochemical polishing of Ti6Al4V alloy after machining is investigated for different ethanol/glycol ratios of polishing solution and surface corrosion resistance. Based on this study, the effect of current density on the surface roughness, morphology, and corrosion resistance of WEDM-machined parts was also analyzed. By optimizing the ethanol/glycol ratio and current density, a micron-sized impurity-free Ti6Al4V surface was obtained at a glycol/ethanol ratio of 4:1 and a current density of 0.55 A cm⁻², and the surface roughness (<i>Ra</i>) was reduced from 3.69 to 0.40 μm.

XRD analysis and Raman spectra confirmed the presence of the anatase phase of TiO₂NTs, while Raman also identified the presence of the grape skin extract (“dye”) on the surface of the film. FEG-SEM images revealed TiO₂NTs the presence of tubes with lengths of 1263.33 ± 58.59 nm and diameters of 92.7 ± 21 nm. DRS spectra and Tauc plots allowed to estimate the bandgap values of TiO₂NTs films between 3.00 and 3.20 eV. The electrochemical characteristics of the ITO/TiO₂NTs films, decorated or not with AgNPs and dye, were evaluated by transient photocurrent (TP) and electrochemical impedance spectroscopy (EIS) on different compositions. The TP analysis showed that the photoanode did not respond without a light source, but when UV light was applied it showed significant photocurrent responses. The best result was obtained with the ITO/TiO₂NTs-dye composition, due to the reduction in bandgap value and the higher visible radiation absorption. EIS analysis showed a significant reduction in the charge transfer resistance in the TiO₂NTs films when exposed to UV radiation, and the dye deposition onto ITO/TiO₂NTs surface caused significant changes in the electrode’s properties. Finally, the films presented in this study can potentially contribute to the capture of solar radiation and conversion into electricity in DSSCs, being a sustainable and highly attractive alternative for energy production.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 3","pages":"887 - 900"},"PeriodicalIF":2.6,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This high surface area can increase side reactions and cause a rapid decline in capacity. Sulfur doping on the surface of the material is achieved through secondary modification with thiourea treatment, resulting in enhanced electrochemical properties and stability. Elemental and morphological characterization, along with electrochemical testing, shows that sulfur surface doping effectively mitigates the rapid capacity decay associated with a high specific surface area.

Photoelectrochemical measurements supported the occurrence of incorporation of citrate anions when anodizing is carried out in a citrate-containing solution. Indeed, two different absorption thresholds were estimated due to energy transitions involving localized states in the mobility gap. Differential capacitance measurements showed higher capacitance values for anodic oxide grown in the citrate-containing solution, with a beneficial effect on the dielectric constant. The increased capacitance can be explained considering the synergistic effect of a more favourable anodizing ratio provided by the presence of Si cations from the bare alloy as well as the incorporation of foreign species due to the inward migration of citrate anions from the electrolyte during the anodizing process.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 4","pages":"1467 - 1476"},"PeriodicalIF":2.6,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10008-024-06087-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632359","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}

Legislation based on the <i>Codex Alimentarius</i> establishes quality control parameters essential for ensuring the safety and quality of honey. These parameters include the measurement of hydroxymethylfurfural (HMF), an indicator of honey quality. Currently, the primary methods for determining HMF concentration in honey are spectrophotometric and chromatographic tests. This study proposes a simpler alternative electroanalytical methodology that uses a screen-printed carbon electrode to monitor the HMF in honey. This portable technique offers advantages over commonly used methods, such as lower cost, similar efficacy, and requirement of only 70 µL of solution per analysis. Square-wave voltammetry was employed to determine HMF in Britton-Robinson buffer (pH 9.0), and the technique was optimized based on the experimental design, generating statistical chemical prediction results. The optimal values for modulation amplitude, step potential, and frequency were 81.5 mV, 22.5 mV, and 5 Hz, respectively. The recovery rate was within the limits established by AOAC International (80–110%), except for the concentration of 6.0 × 10⁻⁷ mol L⁻¹, which showed a 2.07% higher recovery, indicating a minor matrix effect.
