By contrasting the inhibition effectiveness (%IE) with and without the extract, the inhibition efficiency was ascertained. It was found that the corrosion inhibition efficiency increased at higher extract concentrations, peaking at 93.7% at 300 ppm and 25°C, and that the temperature had an opposite effect. According to the PDP data results, sumac extract functions as a mixed-type inhibitor. Generally, the Langmuir adsorption isotherm matched the adsorption process. The extract adsorbs spontaneously onto the metal surface, according to thermodynamic conditions. Analyses of the corrosion product using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) revealed that a protective layer was formed on the metal surface. The outcomes from the several tested methods agreed rather well.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 2","pages":"202 - 222"},"PeriodicalIF":0.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, TiO2 nanotubes (TNTs) were fabricated via the electrochemical anodization method and subsequently their surfaces were modified with Cu nanoparticles using a UV light assisted photo-reduction method. Tubular morphology and mixed phase (anatase-rutile) of TiO2 were confirmed through field emission scanning electron microscopy and X-ray diffraction studies. The energy dispersive spectroscopy data confirmed the deposition of Cu onto the TNT surface. Diffuse reflectance spectroscopy study showed an electronic band gap of TNTs as 3.2 eV. The surface-modified TNTs samples demonstrated an enhanced sensitivity of 0.12 mA mM–1 cm–2 towards glucose detection and a higher photocurrent response of 0.28 mA cm–2 compared with those of pure TNTs samples.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 2","pages":"154 - 163"},"PeriodicalIF":0.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The grain refinement reduces the grain size to the sub-micro scale through increasing the grain boundary (or grain perimeter). The structural elements size is reduced to 169 nm for Zr–1% Nb and to 185 nm for Zr–2.5% Nb. During the phase transformation, β-Nb precipitates dissolve in α-Zr matrix to form a supersaturated solution. To demonstrate the effects of those processes on pitting resistance of zirconium alloys before and after ECAP, cyclic potentiodynamic polarization tests in a chloride-containing solution (Ringer) were performed. The results revealed that the corrosion rate (corrosion current density) decreased for nanostructured zirconium alloys, enhancing the corrosion resistance after ECAP. However, the phase transformation induced during ECAP reduced passivity and pitting resistance to chloride ions in alloys with low Nb content. In contrast, no significant change was observed during the two-phase to single phase transformation in high Zr–Nb alloys.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 2","pages":"223 - 233"},"PeriodicalIF":0.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to clarify the dependence of the properties of ITO films on the substrate temperature and the ratio X = SnO2/In2O3, the layers were synthesized in the temperature range 170–500°С in various X ratios solutions of indium and tin chlorides. The technological modes of the synthesis were set by controlling the temperature of the substrate and evaporators, to which alcoholic solutions of indium and tin chlorides were supplied, as well as by changing the ratio of the components and the rate of supply of the solution. Under such synthesis conditions, the film growth rate was ∼0.5–1.0 µm/h, which is much higher than in the case of spray pyrolysis under similar conditions. The thicknesses of ITO films were determined by using an MII-4 interference microscope and the transmission spectrum; the film thicknesses amounted to ∼3 μm. The dependence of the resistivity of ITO films on the substrate temperature has been studied. It was shown that the films obtained at the substrate temperatures of 240–260°C had a relatively low resistivity, so the films are of interest for solar cells applications. The X-ray spectra of ITO films were analyzed by identification with the map 00-006-0416 (In2O3, cubic) from the Joint Committee on Powder Diffraction Standard database. The average value of the lattice constant was calculated, and it was a = 10.1273 Å, thus being slightly larger than the lattice parameter of pure In2O3 (10.1195 Å), which is associated with the presence of Sn that affects the behavior of oxygen ions.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 2","pages":"148 - 153"},"PeriodicalIF":0.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermodynamic conditions (Т = 1100–1250°С and t = 5–20 h) and technological modes were determined for low-temperature, two-stage diffusion of impurity atoms of germanium, which made it possible to obtain a material with binary compounds GexSi1–x on the surface and near-surface of silicon with given electrophysical parameters. From the results of the study of the concentration distribution of the formed binary compounds GexSi1–x in silicon, it was established that compounds with the maximum concentration were formed on the surface, and their concentration decreased with depth into the volume of silicon. It was found that the compounds GexSi1–x formed in silicon lead to a change in the forbidden zone width of the original material. It is shown that the change in the forbidden zone width of the original silicon due to the formation of binary compounds GexSi1–x changes one of the fundamental parameters of the material, which, in turn, leads to an expansion of the spectral region of sensitivity, which is typical in the development of efficient photocells with a wide range of solar radiation absorption.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 2","pages":"234 - 239"},"PeriodicalIF":0.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145164488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
