This work presents the development of a method for the synthesis of calcium silicate nanoparticles stabilized with essential amino acids. CaSiO3 nanoparticles were obtained through chemical precipitation. In the first stage, the optimal calcium-containing precursor was determined. The samples were examined using scanning electron microscopy. It was found that Ca(CH3COO)2 was the optimal calcium-containing precursor. Then, the phase composition of calcium silicate was studied using X-ray phase analysis. The results showed the presence of high-intensity bands in the diffractogram, which characterized the phase of the nanosized CaSiO3—wollastonite. In the next stage, the influence of the type of amino acid on the microstructure of calcium silicate was studied. The amnio acids studied were valine, L-leucine, L-isoleucine, L-methionine, L-threonine, L-lysine, L-phenylalanine, and L-tryptophan. The analysis of the SEM micrographs showed that the addition of amino acids did not significantly affect the morphology of the CaSiO3 samples. The surface of the CaSiO3 samples, both without a stabilizer and with amino acids, was represented by irregularly shaped aggregates consisting of nanoparticles with a diameter of 50–400 nm. Further, in order to determine the optimal amino acid to use to stabilize nanoparticles, computerized quantum chemical modeling was carried out. Analysis of the data obtained showed that the most energetically favorable interaction was the CaSiO3–L-methionine configuration, where the interaction occurs through the amino group of the amino acid; the energy value of which was −2058.497 kcal/mol. To confirm the simulation results, the samples were examined using IR spectroscopy. An analysis of the results showed that the interaction of calcium silicate with L-methionine occurs via the formation of a bond through the NH3+ group of the amino acid.
The relevance of the research topic is related to the most important religious and philosophical concepts of the late 19th early 20th centuries, in which the mission of technology was defined as a special way of returning to the integrity of being.
The purpose of the article is to consider the ideas of N.F. Fedorov, P.A. Florensky, F. Dessauer on the role of technology in the embodiment of the divine purpose and the transformation of the world.
Comparative approach was used in the study as the main methodological approach. It contributed not only to the disclosure of the features of the authors ideas, but also made it possible to draw a conclusion about the general trends in determining the ontological status of technology in the religious and philosophical works of the period under consideration.
In the conclusion of the article, it is noted that the purpose of technology in the concepts of N.F. Fedorov, P.A. Florensky, F. Dessauer is associated with its ability to overcome decay and restore unity: man with God, divine with natural, natural with social, etc. through culture, understood as human activity, sanctified by the Creators purpose.
The relevance of the research presented in the article is associated with the need to determine the socioanthropological factors of the formation of modern urban space. The aim of the study is to determine the possibilities of using the social activity of people as a manifestation of their freedom and responsibility for the formation of the city's space. The spatial characteristics of the city include the structure of the city, the types of spaces included in it, the hierarchy of urban spaces and subspaces and their connections. Methods of urban space development are primarily determined by production methods and social relations, a complex system of social ties and the influence of different social groups, the role of government and business. As a result of the study, it can be concluded that the development of social activity of city residents, aimed at the formation of urban space, allows one to effectively implement the ideas of citizens, satisfy their needs and, to a certain extent, produce new meanings of the cultural space of the city. It is important to define social activity within the dialectic of freedom and responsibility, which allows residents to become real participants in the development of urban space. The possibility of free participation in the creation of urban spaces, the development and implementation of modern social technologies for such participation (public hearings, polls, city Internet portals, etc.) contribute to the formation of a sense of belonging and responsibility for the city.
