The geometry was optimized at three theory levels (MMFF94, B3LYP and M06), and the following analysis was conducted with the separately saved optimum geometry in each instance. Two families of molecular descriptors (FMPI and EChP) were used to derive structure-based descriptors. Simple linear regressions were extracted with the best of descriptors for each family and level of theory for both potentials. The study revealed that the MMFF94 optimum geometries best explained the selected electrochemical properties. Furthermore, the EChP family of descriptors, much bigger than FMPI (about 64 times), was able to better explain the connection between the structure and the property. Once more, it has been shown that the eigenproblem has deep roots in structural chemistry.","PeriodicalId":14819,"journal":{"name":"Journal of Electrochemical Science and Engineering","volume":"55 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141798826","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}

Herein, we report the electrochemical and supercapacitive behaviour of the liquid redox of catocene, 2,2’-bis(ethyl-ferroceneyl) propane, self-assembled on a basal plane pyrolitic graphite electrode in comparison to the solid ferrocene thin film in aqueous sodium sulfate electrolyte. The modified electrode surfaces were evaluated to assess the iron content and the formation of thin film using scanning electron microscopy, laser-induced breakdown spectroscopy, and attenuated total reflectance method. Also, the supercapacitive performances of the related modified electrodes were assessed and compared using cyclic voltammetry and galvanostatic charge-discharge in a three-electrode system and an asymmetric two-electrode supercapacitor system. Electrochemical results showed that the electrode processes are diffusion-controlled with battery-like behaviour, and the liquid catocene exhibits more effective interaction with the graphite surface in comparison to solid ferrocene. The catocene surface coverage on graphite is nearly 50-75 % higher than ferrocene, leading to improved interaction and charge transfer resistance, observed in electrochemical impedance spectroscopy studies. In galvanostatic charge-discharge evaluations, the supercapacitor based on catocene modified electrode shows a specific capacitance of 141.2 F g-1 at a current density of 1.0 A g-1, with a specific energy density of 56.7 Wh kg-1 at a power density of 2.9 kW kg-1.","PeriodicalId":14819,"journal":{"name":"Journal of Electrochemical Science and Engineering","volume":"66 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141812716","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 research has been accomplished by weight loss measurements, linear polarization resistance (Rp) monitoring and electrochemical impedance spectroscopy (EIS). Phytochemical analysis and Fourier transform infrared spectroscopy were performed to determine bioactive components and detect the main functional groups of Bidens pilosa extract, respectively. The morphological characterization of the substrate was carried out by optical microscopy (OM). Different isotherms were evaluated to understand more clearly the adsorption mechanism of the inhibitor extract molecules on the surface of the 1008 carbon steel substrate, and the best fit was obtained for the Langmuir isotherm. The results showed that the corrosion rate decreased with an increase of the concentration of the inhibitor up to 1000 ppm, reaching a maximum efficiency value of 82.9 % from gravimetric tests, and 73.1 % from the fitting of EIS data to an equivalent electric circuit. The calculated thermodynamic parameters suggested the formation of a monolayer of inhibitor molecules on the metal surface. The ΔGoads value (-22.8 kJ mol-1) determined from the Langmuir isotherm model indicated that adsorption of the inhibitor molecules on the substrate surface follows a physisorption mechanism. This research revealed that Bidens pilosa extract can be used as a corrosion inhibitor and emerges as an alternative to replace synthetic corrosion inhibitors that are harmful to health and cause damage to the environment.","PeriodicalId":14819,"journal":{"name":"Journal of Electrochemical Science and Engineering","volume":"104 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141812120","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 surface's energy often controls its hydrophobic state. There are numerous techniques to realize a change in the surface energy. Smart nano-based materials are being used to create super hydrophobic coatings that will serve as layers of defence against mechanical abrasion, corrosion, and fouling agents on the surface of metallic components. These coatings, which have recently gained popularity, have shown to be excellent choices for protecting steel pipelines. The recently created super hydrophobic coatings for glass surfaces, papers, cotton, steel pipes, etc., are examined in-depth and critically in this review study, emphasizing their use in different industries. It explains how to create super hydrophobic coatings on glass substrates using various techniques and the most recent research results on various coating production techniques. An in-depth discussion is also given to the recent applications of these created super hydrophobic coatings for treatments, including anti-bio fouling, dicing, and corrosion prevention over the past five years. According to the literature, spraying is the most adaptable and popular technique for creating super hydrophobic coatings for any substrate.","PeriodicalId":14819,"journal":{"name":"Journal of Electrochemical Science and Engineering","volume":"52 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141818065","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 electronic properties of the interaction between the inhibitor molecule and the CS substrate were studied using molecular dynamics (MD) simulation, density functional theory (DFT), and Fukui functions. According to AC impedance experiments, the inhibitor under consideration showed a maximum level of 98.1 % inhibition efficiency at 1 mM and 30 °C.

The inhibitory properties of TEPI were assessed through various methods, including electrochemical, spectroscopic, and surface analysis, as well as quantum chemical calculations. The protective effect of C35E was seen to expand as the TEPI amount was extended but to diminish as temperature was augmented, fulfilling 98.3 % at 1 mM under 303 K. Certain thermodynamic and kinetic indices were estimated and explored. The TEPI complied with the Langmuir adsorption isotherm when it adsorbs on the C35E surface. TEPI behaviour was revealed by polarization trials to be of mixed type. The establishment of an adsorption-linked preventive TEPI layer on the C35E surface has been disclosed thanks to surface analysis. The outcomes of scanning electron microscopy coupled with energy dispersive X-ray spectroscopy clearly illustrate that TEPI can efficiently adsorb at the C35E interface, substantially reducing C35E steel corrosion. UV-visible analysis of the inhibited electrolyte clearly reveals the complexation of iron cations with TEPI molecules. The density functional theory, Monte Carlo and molecular dynamic simulation were adopted to check out the adsorption characteristics of the TEPI onto C35E surface. The laboratory outcomes have been proven by DFT and MDS.","PeriodicalId":14819,"journal":{"name":"Journal of Electrochemical Science and Engineering","volume":"28 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140752726","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}

A 2×2 cm square model was created and sliced in Ultimaker Cura software, uploaded in a 3D printer, and printed from the copper electrolyte on the stainless-steel surface. Low additive concentration in the electrolyte was found to influence dendrite formation in the corner sections of a square model. Nozzle movement speed was found to influence the deposition area and the thickness of the metal. The lowest tested nozzle movement speed of 5 s / voxel increased the deposition area by nearly 40 % in horizontal direction compared to 2.5 s / voxel. Further increase of nozzle movement speed to 1.6 s / voxel does not change the deposition area. The thickness in the corners increases by 2.5 times compared to the straight section of the square when the nozzle movement speed increases from 5 to 1.6 s / voxel. The non-uniform thickness of the deposited metal is caused by a considerable reduction of nozzle movement speed when it moves through the corner.
