The strategy for managing such waste involves its fractionation, primarily aimed at extraction and separation of americium and curium. The separated fraction containing curium and rare earth elements (the Cm/REE fraction) is subject to temporary storage, which highlights the need for the development of durable matrices for its immobilization. In this work, samples of a magnesium potassium phosphate compound containing up to 10.7 wt % of a REEs mixture (including Nd, La, Ce, Sm, Gd as a simulant of the separated Cm/REE fraction) were synthesized. The phase composition of the compound, its compressive strength, resistance to freeze–thaw thermal cycling, water resistance, and hydrolytic stability were determined. The compound exhibits high hydrolytic stability: the leaching rate of REEs after 365 days of contact with water is approximately 7.4 × 10–7 g/(cm2 day). It was established that the quality indicators of the compound containing up to 6.4 wt % REEs meet the regulatory requirements for solidified radioactive waste.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 7","pages":"1054 - 1061"},"PeriodicalIF":1.5,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148859800","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}

It was found that, at a H2O2 concentration of 6 mol/L in the reaction system, a solid phase with a tetragonal crystal lattice typical of SnO2 is formed. According to X-ray diffraction data, the size of the coherent scattering region increases with increasing temperature from 2.3 ± 0.2 (50°C) to 3.3 ± 0.3 (300°C) and 7.9 ± 0.3 nm (500°C). According to transmission electron microscopy, individual oxide nanoparticles are mainly single crystals, the average particle size after drying at 50°C is 1.9 ± 0.5 nm, and heat treatment at 500°C leads to its increase to 9.0 ± 1.8 nm. Scanning electron microscopy indicates the formation of agglomerates ranging in size from 28 ± 7 nm (50°C) to 32 ± 5 nm (500°C), which is caused by sintering of particles during high-temperature heat treatment. Using Kelvin probe force microscopy, the work function of electrons from the surface of the materials was estimated and it was determined that heat treatment leads to a decrease in this value from 4.9 eV (for the sample dried at 50°C) to 4.5 eV (500°C), which correlates with an increase in the electrical conductivity of the materials. The powder annealed at 500°C was used to form a film using microextrusion printing to study the chemosensory properties of the coating.

The structural, morphological, and electrochemical characteristics of the composites, as well as the features of their degradation under different lithiation regimes were examined using X‑ray diffraction, scanning electron microscopy, liquid porosimetry, cyclic voltammetry, electrochemical impedance spectroscopy, and galvanostatic cycling. Increasing the silicon content leads to an increase in the porosity of the electrode active layer and the anode capacity, which is due to the high electrochemical capacity of silicon. Coulometric capacity limitation (1000 mA h/g) does not prevent degradation of the composites because of the progressive deepening of silicon lithiation and the formation of a crystalline Li3.75Si phase, causing a sharp capacity drop. In contrast, applying a potentiostatic lithiation cut‑off (170–190 mV) limits lithiation to the amorphous silicon layer, preserving the crystalline core and significantly improving cycling stability. The best cycling stability was achieved for the composite containing 20 wt % silicon (capacity loss of 6% over 100 cycles).

Particular attention is paid to the influence of the component ratio on the rheological behavior of the initial mixtures, the features of gradient structure formation during printing, as well as on the microstructure and phase composition after heat treatment. The Ti3SiC2/bronze composite is formed by extrusion additive printing followed by sintering at a temperature of 1070°C without significant reactionary phase transformation. With different bronze content in the composite, the structure is represented by Ti3SiC2, TiC, α-Cu, κ-phase (Fe3Al) and β-phase (Cu3Al) phases, with an observed tendency for the α-Cu phase to increase as the bronze content increases. It is shown that variation in the content of the metallic component has a complex effect on the material flow process, extrusion stability, and the formation of interfacial boundaries. Limitations on the bronze content are established, due to the characteristics of flow and structure formation: no more than 10 vol %.

This study is devoted to obtaining closo-decaborate derivatives capable of self-assembling into stable nanoassemblies in aqueous media, with the aim of further investigating them as new delivery systems for boron-containing substances promising for boron neutron capture therapy of cancer. To obtain closo-decaborate derivatives, an approach to squalenoylation of closo-decaborate clusters by alkylation of monoalkylthio derivatives of closo-decaborate with squalene bromohydrin was considered. Nanoassemblies of the synthesized conjugates of squalene with butyl- and nitrilopropylthio derivatives of closo-decaborate were obtained in aqueous media by nanoprecipitation. The obtained systems were studied by dynamic and electrophoretic light scattering.
