The article examines the principles of developing micro-districts and settlements for individual housing construction. It emphasizes the integration of environmental, innovative, and social aspects into the design and planning processes of such areas. These measures not only enhance the comfort and safety of living but also significantly reduce operational costs, thereby making projects more economically viable. The focus is on the necessity of a comprehensive and interdisciplinary approach to the planning and development of infrastructure in areas designated for individual housing construction. The article also addresses issues related to the infrastructure of micro-districts designed for individual residential development. By analyzing existing practices, it has been found that contemporary urban planning approaches are increasingly oriented toward creating sustainable and comfortable urban environments. A comprehensive analysis of the problem has enabled the identification of the essential components of infrastructure for areas intended for individual housing development. The article underscores that achieving sustainable development in such territories can only be attained through clear regulation of various indicators characterizing these areas.

The construction industry is undergoing regular changes these days, influenced by many different factors. Large and structurally complex construction projects reveal more and more imperfections in traditional construction methods, e.g. increased time or production costs, downtime, delays, etc. Lean construction and its principles have emerged in search of solutions to problems in construction. In the search for solutions to problems in construction, the term - lean construction and its principles appeared, which replaced traditional methods and aimed at finding new approaches in the implementation of construction activities. In this scientific article the definition of Lean Construction is given, and also the history of Lean Construction and its chronology are considered. The comparison of the traditional construction model and Lean model is given, and also the connection of Building Information Modeling (BIM) with Lean Construction principles is analysed and an example of this connection is given.

Physical education at the present stage of world development of society takes the form of a social phenomenon, is to strengthen the role of sport in the lives of everyone. Variety of sports meets a wide range of specially adapted facilities. The problem of technical modernization, stadium reconstruction and development as a multi-functional sports facilities (IVS). Profitability maintained and advanced facilities can be improved by putting into practice the principles of design of architectural form and structural theoretical model of the spatial organization of the IVS.

The composite cathode material of the core@shell type with the LiMn2O4@LiCoO2 formula of has been successfully synthesized using the solid-state reactions in several stages. Its structure has been studied by means of X-ray diffraction, scanning and transmission electron microscopy and vibrational infrared spectroscopy. Electrochemical investigation in two-electrode cell has been showed improvement of characteristics of the synthesized cathode material than the constituent components. The specific power of LiMn2O4@LiCoO2 is 650 mWh/g, against 450 and 500 mWh/g for LiCoO2 and LiMn2O4, respectively.

To date, the main method of mass production of advanced functional materials for various purposes is the ceramic technology. In the manufacture of multi-component oxide compounds using of ceramic technology is difficult to achieve high uniformity of chemical composition. For activation of the raw ingredients and make it more uniform use of chemical-tions (co-precipitation of salts or hydroxides, spray drying, Cryochemistry) and physical-tions (mechano-chemical, microwave, ultrasonic) methods. The paper presents the results of work on obtaining Ni-Zn-ferrite 2000NN radiation-thermal sintering. The influence of base composition and alloying additions on the electromagnetic properties of the ferrites. Confirmed the effectiveness of the use of surface-active additives To increase the density of the raw pieces and level parameters. We propose a model that explain schaya efficiency of dopants in the radiation-thermal sintering.

Laboratory technology was developed to fabricate flexible piezocomposites with ferroelectric phase - polymers having signal reception factorv • gv 5000 • 10-15 m2 / N. The values of the given coefficient were achieved by switching from a probabilistic (spontaneous) percolation to a correlated one in the process of forming material. This made the production of 0-1–3 piezocomposites, in which a part of piezophase has 0 connectivity, and the other part – 1 connectivity possible. To improve the efficiency of piezocomposite polarization before their manufacturing the surface of piezophase particles, which were obtained by the partial destruction of the porous frameworks, was treated with coupling agent, which did not only improve the polymer adhesion to piezophase, but also allowed the removal of water from the particle surface. The latter effect reduced the value of interfacial conductivity, i.e. prevented the voltage drop of the polarizing field. Matching of polymer conductivity and piezoceramic particles by determining the optimal polarization temperature was carried out as well.
