It has been established that cluster structures in the silicon crystal lattice ensure the stability of electrophysical parameters over a wide temperature range and high radiation resistance to γ- and electron irradiation. It has been shown that, at Ni cluster concentrations ≥1015 cm–3, the generation of thermal donors and radiation defects is suppressed without altering the conductivity type. Impurity atoms with unfilled d- and f-shells (Mn, Cr, Gd, Eu) have been found to form ferromagnetic states in silicon, controllable by an external magnetic field at room temperature. Multicharged Mn nanoclusters were found to create localized energy levels within the forbidden bandgap, explaining the observed negative magnetoresistance and impurity absorption with an edge at 0.2 eV. For selenium-doped silicon, the possibility of creating pulse generators with frequency modulation suitable for detecting monochromatic radiation has been demonstrated. The study of binary compounds in the silicon lattice confirmed their stability and potential for developing materials with controllable photoelectric, optical, and magnetic properties.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"60 - 73"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588570","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 steel surface was saturated with sulfur in an electrolyte based on ammonium sulfate and dimethylsulfoxide at 550°C. Before and after diffusion saturation, various types of heat treatment were applied: quenching from 780°C after sulfiding, tempering before and after saturation from 780°C. An analysis of the structural and phase changes in the sulfided surface revealed the formation of FeS, Fe3S4, and Fe2S3 iron sulfides, the amount of which is determined by the use of heat treatment before and after saturation, and the formation of martensite after quenching and Fe3O4 oxides as a result of high-temperature oxidation. Tribological tests were conducted in the dry friction mode using the “shaft-bushing” scheme under a load of 10 N and the sliding speed of the sample on the counter body of 1.555 m/s per 1000 m of the friction path. An increase in weight wear after plasma electrolytic sulfiding with quenching was found to be 17 times greater than that of an untreated sample, 13 times greater than that of water- and oil-quenched samples, and 14 times greater than that of tempered samples. The wear resistance of sulfided steel was determined by the structure of the deformation zone material during friction, containing iron sulfides.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"10 - 15"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588470","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}

Knowledge of the physical and electrochemical properties of the NPs, such as their crystalline phases, shape, electrical conductivity, surface characteristics, and charge transfer resistance, is critical for enhancing their biosensor performance. Those properties were analyzed using ultraviolet-visible absorbance, X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, cyclic voltammetry, and electrochemical impedance spectroscopy. The study also explored functionalization options for improving the interaction between TiO2 surfaces and target analytes, increasing the overall efficiency of electrochemical sensors. The results showed that the synthesized particle size was 22 nm, indicating an increase in the surface area, allowing the glassy carbon/TiO2-modified electrode to store input energy and then discharge, similar to a capacitor. Furthermore, the glassy carbon/TiO2-modified electrode demonstrated high sensitivity and stability. The findings suggest that environmentally synthesized TiO2 NPs can markedly accelerate the development of reliable and effective biosensing systems.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"16 - 24"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588568","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}

Polishing was carried out under conditions effectively shown for treatment products made of titanium alloys obtained by the traditional method. An aqueous solution at 80°C based on ammonium fluoride with the addition of citric acid and pyrocatechol as complexing agents was used as an electrolyte. It was found that treatment at a voltage of 300 V for 20 min reduces the height roughness parameters Ra and Rz by an order of magnitude. Tribological tests were conducted in the dry friction mode using the shaft-bushing scheme under a load of 10 N. At a sliding speed of the sample on a counter body made of hardened tool steel of 1.555 m/s per 1000 m of friction path, there is a decrease in weight wear by 1.8 and 1.9 times and the friction coefficient by 10 and 42%, respectively. Improvement of antifriction characteristics is ensured after polishing for 15 and 20 min by the formation of a self-reproducing stable microrelief with high load-bearing capacity of a rough profile under friction, with the leading role of the oxidative wear mechanism.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"1 - 9"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588572","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 relevance of the present work is due to the widespread use of electrolysis in the production of hydrogen, chlorine, and alkalis and other areas where overvoltages caused by kinetic constraints are a key factor in energy losses, reducing the economic feasibility of technologies. The methodology included a comparative analysis of the electrode materials (Pt, ORTA, graphite, AISI 430, Fe, Ni, Cu, Al) in solutions of H2SO4, NaOH, Na2SO4, and Na2S with the construction and analysis of the anode and cathode Tafel curves to determine kinetic parameters. The results presented by the polarization curves showed a significant dependence of overvoltages on the nature of materials and the composition of electrolytes. Platinum showed the lowest overvoltage values. The ORTA material exhibited ambiguous behavior with a sharp decrease in efficacy in alkaline solutions. Graphite, despite its consistently high overvoltage, confirmed its chemical inertness. Metal electrodes have shown a complex dependence on the electrolyte. The most effective solution was found to be the combination of the AISI 430 stainless-steel cathode with the ORTA anode, which provides the optimal ratio of efficiency and economy. The correct choice of materials and electrolyte significantly increases the energy efficiency of the process.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 6","pages":"832 - 841"},"PeriodicalIF":0.7,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706198","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}

It is shown that, in the case of a two-range inverter control strategy in overmodulation mode, modified algorithms of a synchronous pulse-width modulation, including the use of specialized correction coefficients for each sub-range of the overmodulation zone, allowed for the continuous synchronization and symmetry of the basic voltage waveforms on the inverter-side windings of the power transformers of photovoltaic systems throughout the entire inverter overmodulation zone. Modeling the processes in the systems confirms the absence of harmonic components of even order and of subharmonics of the fundamental frequency of photovoltaic stations in the spectra of the basic voltages of the analyzed photovoltaic installations over the entire range of two-stage regulation of inverters in the overmodulation zone. This improvement in the harmonic composition of basic voltages decreases losses and increases the efficiency of photovoltaic installations based on inverters with synchronous modulation, which is particularly important for high-power systems characterized by a relatively low switching frequency of the power switches of inverters.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 6","pages":"951 - 959"},"PeriodicalIF":0.7,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706121","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}
