The compound antimicrobial activity was evaluated. The compound showed a moderate to strong inhibitory action towards a selection of Gram-positive (S. aureus, S. epidermidis), Gram-negative (Klebsiella spp., and E. coli), and fungal (Candida albicans) species, and its activity increased at higher concentrations. The compound electronic structure, molecular orbitals, and vibrational properties were studied using DFT and TD-DFT calculations. The bioactivity exhibited was explained by the proposed charge transfer mechanism evinced by the HOMO-LUMO energy gap and a dipole moment as well as the bioactivity exhibited by the studied compound. This is the chalcone derivative potential applications in electrophysiology. The chalcone derivative is a promising candidate for further study as an antimicrobial surface-active agent or as a functional material in electrochemical devices and coatings, as suggested by the synergy between experimental and theoretical data matching.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"74 - 82"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588571","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}

To address challenges such as coarse grains and porosity caused by concentration polarization during traditional direct current plating, ultrasonic intervals of varying durations were introduced. The surface morphology, crystallographic orientation, grain size, and corrosion resistance were analyzed using scanning electron microscopy, X-ray diffraction, and electrochemical techniques. Results reveal that continuous ultrasound and short-interval pulsing promote (220) texture and yield finer grains, with sample #3 exhibiting the strongest (220) orientation and smallest grain size. Longer intervals shift the preferred orientation to (200), enhance coating compactness and improve thermodynamic stability (higher open-circuit potential), but do not necessarily result in better corrosion resistance. Notably, sample #1 demonstrated the lowest corrosion current density and a balanced polarization resistance, indicating the best overall electrochemical protection. This study highlights the importance of ultrasonic interval tuning to balance structural and electrochemical properties in functional nickel coatings.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"25 - 35"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588375","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 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 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}

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.

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.
