Polyaniline (PAN) and microcrystalline cellulose/polyaniline composite (MCC/PAN) were synthesized by the chemical oxidative in situ polymerization of aniline using ammonium peroxodisulphate as an oxidizing agent in aqueous hydrochloric acid solution. The obtained samples were characterized by infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and X-ray diffraction (XRD). The adsorption properties of the synthesized sorbents for the food dye tartrazine (TZ) were investigated under static model conditions. These materials were evaluated according to various parameters (contact time between the adsorbent and the adsorbate, dye concentration, and adsorbent mass). The obtained kinetic data of adsorption were described by pseudo-second order kinetic equations. The MCC/PAN composite proved to be a better adsorbent material compared to PAN due to its higher adsorption capacity (q = 99.0 mg g−1), which can be explained by the combination of the adsorption properties of the two materials and the morphology of the composite.

Today’s modern society is developing quite dynamically due to the use of the latest technologies and their implementation in quotidian life. The same trends are characteristic for the development of higher education and all participants involved in this process. The purpose of the article is to analyze the mutual influence of the professional training of future scientific and pedagogical workers and the trends of education digitization. Particularly, the importance of acquiring digital competence was established – the importance of this process was confirmed by the use of content analysis of the literature: search engines found 60 most concerning articles for the years 2015–2023. In the results, materials of empirical and theoretical content were elaborated. It should be noted that students in Ukraine are not enough competent in the use of igital technologies, but some of them have not completely realized the essence of the responsibility and academic integrity regarding the use of various sources. The results also show that there are a number of difficulties (for example, lack of motivation and knowledge about digital competencies) in the professional training of future scientific and pedagogical workers using digital technologies. The conclusions summarize that digital skills will become especially relevant in the future, so the training of teachers and scientists should pay great attention not only to the use of digital technologies and resources in teaching, but also theoretical counseling, the formation of students' ability to critically perceive the digital content. Therefore, the system of professional training of future scientific and pedagogical workers should focus on the formation of digital literacy, critical thinking, and information competence of students. At the same time, the mutual influence on the digitalization of education is possible. Thanks to the cooperation with employers, teachers will change the content of training in accordance with the current requirements of the labor market, so digital training mechanisms will also need an improvement.

Open Russian aggression against Ukraine, which began on February 24, 2022, quite predictably had a negative impact on the whole Ukrainian society. At the same time, employees of pedagogical and scientific industries experienced significant pressure, as they were among the vulnerable categories of the population subjected to special repressions in the occupied territories, and in subordinate Ukraine experienced restrictions due to the general fall of the standard of living. With this in mind, the purpose of the article is to analyze the psychological health of the personnel of educational and scientific institutions during martial law in Ukraine. Methods of comparison, content analysis, systematic approach, abstraction, predictive method, and modeling were used to write the floor. As a result, based on theoretical knowledge and certain empirical generalizations the formation of psychological problems of teachers and mechanisms of their overcoming are demonstrated. Particularly, the constituent parts of professional burnout of pedagogical workers are demonstrated, but also the mechanisms of protection against stressful situations which are available for use even during the continuation of military operations are suggested. The article also draws attention to the problem of the psychological health of scientific workers - it says about the gradual decline of labor prestige and funding of the scientific industry, especially intensified during the war. The average age of scientists in Ukraine is quite high, so it entailed a decrease in the level of self-control and increased dependence on the opinion of others. The conclusions summarize ways to improve the psychological state, noting that the continuation of war and destruction will have a further negative impact.

The purpose of the article is to analyze the state of Ukrainian education and science in the conditions of global challenges and military aggression. General scientific and special scientific research methods were used. In the results, the current state of education and science in Ukraine was investigated, the main post-truth challenges in the conditions of globalization and Russian military aggression were described, the problems and mechanisms for overcoming were determined in the analyzed fields. The conclusions note that the main way to overcome the crisis is the integration of the Ukrainian model of education and science into the European space.

The relevance of the study is due to the rapid digitalization and computerization of both the educational process and research activities. New challenges are prompting the creation of a new digital educational environment. Relying on the latest digital technologies, scientific paradigms are changing towards creating interdisciplinary areas of research. The article aims to analyze the main trends of digital transformation of the educational and scientific sphere. The article is based on the use of theoretical pedagogical research methods: analysis, synthesis, induction, and deduction. Content analysis of scientific literature showed that researchers do not pay enough attention to the analysis of tools for implementing the elements of digitalization in the educational and research processes. The results of the study were actualization of the understanding of the content and essence of the digitalization of the educational process, coverage of the competence approach to the implementation of digitalization, analysis of the formation of new interdisciplinary areas of research work. Practical significance: the creation of recommendations on the implementation of digital competence acquisition tools for effective adaptation to the new digital educational environment in Ukraine and the disclosure of its additional benefits. In conclusion, it is noted that this study opens a broad discussion on the prospects for changing both educational and scientific paradigms in Ukraine and the world.

The viability of obtaining aluminium coagulant from the solid vinyl chloride production waste (spent catalyst) was studied. The new coagulant Al6(OH)13Cl5 was established to be effective for clarifying water with high levels of suspended substances. The consumption of the new coagulant is...
