The adsorption behaviors of anthracyclines in both water and acetone molecules were investigated, providing insight into the interaction mechanisms at the molecular level. Through the application of various adsorption models, the study evaluates the impact of solvent polarity on the efficiency and specificity of anthracycline adsorption. Furthermore, molecular docking simulations were employed to elucidate the binding affinities and potential mechanisms of interaction between anthracyclines and human lung cancer protein (ID: 2P85).

These materials are flammable. To reduce their flammability and combustibility, fire retardants with different mechanisms of action are used. The paper presents a comparative study of the influence of various fire retardants (melamine phosphate, melamine polyphosphate, melamine borate, and melamine cyanurate) on the process of thermal-oxidative decomposition of ethylene vinyl acetate. The effect of these fire retardants on the heat resistance of the polymer material and the processes of destruction of ethylene vinyl acetate at different stages is described. It has been demonstrated that melamine-based fire retardants, as a rule, increase the heat resistance of the polymer material, shift the polymer degradation range toward higher temperatures, and reduce the weight loss. Among the fire retardants used, the best results in increasing the heat resistance of ethylene vinyl acetate have been achieved in the case of melamine polyphosphate. Melamine derivatives, when decomposed, form, together with the products of ethylene vinyl acetate destruction, refractory and highly condensed phases, which affect the process of gas evolution during the decomposition of polymeric materials, and are also responsible for the formation of foam coke with fragments of the polymer matrix, which has a barrier effect.</p>","PeriodicalId":530,"journal":{"name":"Doklady Chemistry","volume":"520 1","pages":"1 - 11"},"PeriodicalIF":1.0,"publicationDate":"2025-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145479653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper studied the application of multifractal analysis to describe and evaluate the characteristics of disperse polymetallic systems (Fe–Al–Co, Fe–Al–Cr, Fe–Al–Mo) obtained by galvanic substitution. The study resulted in the identification of important aspects, such as the distribution of fractal dimensions, which allows for a deeper understanding of the mechanisms of formation and development of structures in polymetallic systems. The presented results can be useful for the development of new materials and technologies, as well as for improving existing methods of analysis and quality control of polymetallic systems.
