The presence of tungsten on the surface of magnetite particles after sorption was established. Thermodynamic parameters were determined from the approximation of adsorption isotherms at temperatures of 20, 30, 40°C using the Langmuir and Freundlich equations. The adsorption process was found to be exothermic. The standard adsorption enthalpy (Delta H^circ ~) = −7.07 kJ/mol was comparable with the molar interaction enthalpy derived from direct microcalorimetric measurements ((~Delta H^circ ) = −10.17 kJ/mol). Relying on the thermodynamic parameters and IR and X-ray photoelectron spectroscopy data, it was assumed that adsorption was predominantly implemented via physical adsorption mechanism involving electrostatic interaction between ({text{WO}}_{4}^{{2 - }}) and the Fe3O4 surface.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 7","pages":"981 - 988"},"PeriodicalIF":1.5,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148859821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three variants of the phase diagram model are proposed, depending on the number of binary compounds in the UCl3–KCl system. The first variant accounts for the formation of one binary compound K2UCl5, wherein the ternary system is triangulated by the quasi-binary section LiCl–K2UCl5 into two eutectic subsystems. The second variant considers the formation of three compounds: K2UCl5, K3UCl6, and KU2Cl7. The system is triangulated by the LiCl–K2UCl5 section into two subsystems, in each of which the eutectic invariant transformation is preceded by the decomposition of binary compounds. In a third, hypothetical variant, based on the formation of two compounds, K2UCl5 and K3UCl6, the occurrence of three invariant transformations is assumed. The models are constructed across the entire temperature range and account for both the high-temperature phase regions with a melt and the subsolidus regions. The presented digital twins are not only a tool for further study of the LiCl–UCl3–KCl system but also provide predictive opportunities for experimental investigation, depending on the chosen variant of the UCl3–KCl system structure.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 8","pages":"1127 - 1135"},"PeriodicalIF":1.5,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148859783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Por-Al2O3 was formed by anodic oxidation of aluminum foil in an etidronic acid-based electrolyte at various temperatures (T = 5–40°C) and represents arrays of ordered nanopores with diameters ranging from 80 to 110 nm. Using EPR spectroscopy, oxygen vacancies (F+ centers) were detected in all samples, and their concentrations were calculated. Photoluminescence (PL) of por-Al2O3 consists of two bands: at λ1 = 454 nm and λ2 = 585 nm (T = 5–25°C) and at λ1 = 465 nm and λ2 = 635 nm (T = 40°C). It was established that F+ centers are responsible for the PL band at λ1. It was discovered that the contribution to the PL at λ2 comes from nonparamagnetic defects formed as a result of the incorporation of molecular fragments from the electrolyte into the sample structure during anodization. The mechanisms of PL in porous Al2O3 synthesized in etidronic acid were elucidated for the first time, and it was shown that the electrolyte temperature can be used to control the defect concentration and PL intensity.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 7","pages":"989 - 996"},"PeriodicalIF":1.5,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148859822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of these factors on the stoichiometry of complexation and the stability of the axial complexes obtained is determined. The picture of the influence of the chemical structure and, therefore, the basicity of the axial ligand is complicated by the manifestation of steric effects during complex formation, while chloroform and toluene, as media for the reaction, have a very different effect on the equilibrium constant in a series of studied bases added to (Cl)MnOEP.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 7","pages":"936 - 943"},"PeriodicalIF":1.5,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148859797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
