In this study, few-layer Ti3C2 MXene was synthesized and incorporated into ZRPs at loadings of 0, 0.3, 0.6, and 0.9 wt %. The effects of Ti3C2 on the phase composition, electrochemical corrosion behavior and salt-spray resistance of ZRPs were systematically investigated via XRD, Raman spectroscopy, electrochemical measurements and neutral salt-spray tests, with its action and failure mechanisms elucidated. Results showed that Ti3C2 refined Zn grains without altering the intrinsic crystalline phases of ZRPs, and its slight oxidation to anatase TiO2 enhanced the coating barrier property. The optimal Ti3C2 loading was 0.6 wt %, which realized the synergy of physical barrier enhancement, conductive network construction and interfacial reinforcement, endowing the coating with the best corrosion resistance. The main failure mechanism under salt-spray conditions was Cl–-induced hydrolysis of ZnO to loose Zn(OH)2. This study clarifies the key technical parameters and action mechanisms of Ti3C2-reinforced ZRPs, providing a theoretical and experimental foundation for designing high-performance anti-corrosion coatings for severe service environments.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"62 3","pages":"578 - 590"},"PeriodicalIF":1.1,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bitter leaf (BLE) oil extract was investigated for API 5L X70 steel in 1 M HCl solution. With consideration of varying temperatures from 30 to 50°C and inhibitive response from 0, 0.2, 0.4, and 0.6 mL per 50 mL solution the thermodynamics assessment was undertaken using open circuit potential (OCP) and linear sweep voltammetry (LSV). From all indication, BLE exhibited superior inhibition performance, reducing corrosion rate from 1.32 to 0.48 mm/year at 30°C and from 1.87 to 0.78 mm/year at 50°C, while maintaining high polarization resistance values (~47 Ω) across all temperatures. It is important to established that the inhibitors followed Langmuir isotherm behavior, indicating predominantly monolayer adsorption, with Gibbs free energy of adsorption coefficient. The micrograph for BLE-treated samples confirmed the formation of compact and adherent protective films. Response surface methodology (RSM) agrees that inhibitive activities was the dominant factor influencing corrosion rate reduction within temperature changes. The developed quadratic models exhibited strong predictive capability (R2 ≈ 97.8%), with optimal corrosion protection achieved at higher inhibitor concentrations and lower temperatures. Importantly, the results establish bitter leaf extract as a more effective and thermally stable green corrosion inhibitor for API 5L X70 steel in acidic environments.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"62 3","pages":"676 - 685"},"PeriodicalIF":1.1,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transformation of the initial anatase phase (the I41/amd space group) with the formation of a series of polymorphs, namely, a high-pressure phase TiO2-II (columbite, the Pbcn space group), rutile phase (the P42/mnm space group), brookite phase (the Pcab space group) as well as α-titanium (the P63/mmc space group), is noted. It is found that a decrease in the size of crystallites down to ~10 nm results in a gradual increase in the surface area from 8 m2/g (initial anatase) up to the maximum value of 22.5 m2/g (after 600 min of milling). Upon further increasing the duration of milling, a decrease in the indicator down to 16 m2/g (1800 min) is observed due to the degradation of the pore system. Controlling the conditions of milling, it is possible to obtain products with a predefined phase composition and, hence, predefined properties. High-energy milling of titanium dioxide in the modification form of anatase in a titanium milling medium makes it possible to obtain a unique material with the minimum contamination determined by “scuffing” because the process occurs in an oxidative atmosphere by a simple method. Thus obtained products expand the fields of application of the polymorphs of titanium dioxide.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"62 3","pages":"545 - 557"},"PeriodicalIF":1.1,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research aims to evaluate the structural, morphological, and optical enhancements induced by single and co-doping to optimize ZnO for advanced optoelectronic applications. X-ray diffraction (XRD) analysis confirmed that all synthesized films possess a highly crystalline hexagonal wurtzite structure. Notably, the introduction of Mg and Co dopants significantly improved crystallinity, increasing the crystallite size from approximately 18.5 nm in pure ZnO to roughly 30 nm in the co-doped samples. Scanning electron microscopy (SEM) revealed a profound morphological transformation; while pure ZnO exhibited a porous, loosely agglomerated surface, the doped films demonstrated a highly compact, dense, and homogeneous microstructure with well-developed spherical grains. Optical properties, assessed through UV-Vis spectroscopy, showed that all films maintain high transparency in the visible spectrum. The optical band gap widened from 3.21 eV for pure ZnO to 3.26 eV for the MCZO thin films. Furthermore, the Urbach energy significantly decreased from 179 to 99 meV in the co-doped sample, indicating a substantial reduction in structural defects and lattice disorder. Consequently, the synergistic effects of Mg and Co co-doping considerably enhance the structural integrity and optical performance of ZnO thin films, demonstrating their strong potential for high-efficiency optoelectronic devices.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"62 3","pages":"500 - 511"},"PeriodicalIF":1.1,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of a complex of research methods, including scanning electron and energy-dispersive X-ray microscopy, IR spectroscopy, dynamic light scattering, and X-ray diffractometry, made it possible to identify the features of the surface structure and properties of DNDs. It was found that, during the chlorination of DNDs, the concentration of chlorine atoms increased from 0.05 to 6.60 wt %. Differences in particle agglomeration in aqueous media were found for the original and modified samples. It was shown that neither modified and unmodified detonation nanodiamonds has a negative effect on the protozoan paramecium T. pyriformis. The biocidal effect was assessed using nonpathogenic strains of Gram-positive bacteria Paenibacillus jamilae DCB2-2 and Gram-negative bacteria Pseudomonas putida C-49-2. It has been shown that graphitization reduces the biocidal effect of DND on Gram-negative and -positive strains, while aminated and untreated DNDs have a universal biocidal effect.
