The sensor was developed by investigating metal oxide and conductive polymer modifiers on graphene electrodes to enhance the sensitivity for the phenol detection. In this research, the production of an electrode is discussed that is very sensitive to phenolic compounds using a composite of zinc oxide and polyaniline modified graphene (Gr/ZnO@PANi). The Gr/ZnO nanocomposite synthesis was carried out using a simple hydrothermal method and modification of PANi on the electrode surface by the electropolymerization method. It was found that the Gr/ZnO@PANi composite electrode can detect phenol effectively, with an efficient electron transfer occurring at a low oxidation potential. Additionally, it was observed that the electrode sensitivity to the phenol concentration was remarkably linear within a range of 10–6–10–1 M, and its limit of detection was as low as 0.0515 μM. Furthermore, the Gr/ZnO@PANi composite electrode exhibited excellent stability in detecting phenolic compounds, as indicated by the low stability coefficients of the relative standard deviation for reproducibility (0.37%) and the randomized strategic demand reduction (1.02%). Those findings suggest that the new Gr/ZnO@ PANi composite electrode is a promising tool for the sensitive detection of phenol in the environment, which could contribute to mitigating its negative impacts on human health and ecosystems. Future studies could explore the potential applications of this sensor for detecting other types of pollutants as well.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"59 6","pages":"764 - 771"},"PeriodicalIF":0.9,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138630893","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}

However, at present, the role of the volume of the discharge chamber in the formation of the pressure field in it has been insufficiently studied. The purpose of this work is to fill the gap. The study was carried out on the basis of a previously developed mathematical model of an electric discharge in water, the adequacy of which was substantiated via a comparison of the simulation results with experimental data. It is determined that the closed volume of the discharge chamber with rigid walls significantly affects the formation of the pressure field in the water filling it. In this case, the interaction of waves reflected from the walls of the discharge chamber with the surface of the discharge channel in water and the vapor-gas cavity is of decisive importance. The reflected waves determine the period and amplitude of the pulsation of the discharge channel and the vapor-gas cavity, thereby influencing the electrical characteristics of the discharge. This influence increases with decreasing the chamber volume.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"59 6","pages":"742 - 753"},"PeriodicalIF":0.9,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138631031","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}

Experiments determined the optimal gettering conditions for nickel clusters (nickel diffusion temperature 800–850°C and additional thermal annealing temperature 750–800°C) and the structure of a silicon SC that enhances its efficiency by 25–30% in comparison with the reference structure. Physical mechanisms were identified for the effect of the diffusion of nickel impurity atoms and additional thermal annealing on the state of nickel atoms near the surface and the SC base and, consequently, on SC parameters. Physical models were developed for the structure of a cluster of nickel atoms in silicon and for the gettering process of fast-diffusing impurities by clusters of nickel atoms. The binding energy of fast-diffusing impurity atoms with a nickel cluster was estimated to be approximately 1.39 eV. Calculations showed that nickel doping can increase the minority carrier lifetime and the collection coefficient by factors of 2–4 and 1.4–2, respectively. Experiments demonstrated a twofold increase in minority carrier lifetime and a 25–30% improvement in the efficiency of SCs.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"59 6","pages":"858 - 866"},"PeriodicalIF":0.9,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138631604","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 view of the quantum-wave nature of the electric conduction current i0(t), it was found that, in the metal wires of studied overhead lines, there appear the standing transverse electromagnetic waves (EMWs) that cannot transfer electromagnetic energy over a distance. It is demonstrated that, due to a weak dissipation of the quantized longitudinal electronic de Broglie half-waves on the crystal lattice sites of a metal (alloy) of the wires of the studied line, the heat losses of energy are released on those lattice sites. The features of the influence of the traveling transverse EMWs in the air environment of the studied lines on the process of transmission of electromagnetic energy in the overhead power lines over a distance are established.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"59 6","pages":"816 - 823"},"PeriodicalIF":0.9,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139022133","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}

For this purpose, an electroforming setup was made using a copper sulfate electroforming bath. A full factorial method was used to design the experiments with four control factors, each of them of two levels. After conducting each experiment, the prepared copper electroformed samples were characterized using a contact profilemeter and measuring certain surface roughness parameters, namely, the average roughness, the root mean square roughness, the average maximum height of the profile, and the autocorrelation length. Finally, the regression modelling was used to obtain a predictive model based on the measurements data. Also, the Pareto ANOVA analysis was performed for each surface roughness parameter to evaluate the contribution ratio of the control factors. The results demonstrated that a different control factor is dominant for each surface roughness parameter.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"59 6","pages":"780 - 790"},"PeriodicalIF":0.9,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138631256","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}
