The theoretical assessment of energy losses of plasma flow ions moving in a gas environment with a strong difference in the velocity and mass of colliding particles is given. A titanium plasma and a nitrogen environment were taken as example. It is shown that at energies and velocities of ions corresponding to vacuum plasma deposition method the not elastic processes do not play ...

The article provides the definition of "phase change material". Noted that as materials with change phase, with thermoregulation properties, are preferably used paraffin’s. The use of microencapsulation technology allows you to effectively use the phase change materials in various fields. The most commonly used PCM in building, in the manufacture of upholstered furniture and ...

The design of an electric heating element on aluminum with a carbon fiber as a resistive element is described. Nanoporous aluminum oxide in the heater design is used as a dielectric layer serving to electrically isolate the carbon fiber from the heater base made of aluminum. This approach makes it possible to combine the advantages of using a carbon fiber as a heating element ...

This work presents the results of studies aimed at obtaining ceramic materials for thermal units operating in a nonstationary thermal field based on cordierite and wollastonite ceramics using domestic raw materials. The research results can be used for the production of ceramic fuels based on wollastonite and cordierite using natural and man-made raw materials.

This article considers the possible influence of modern blockchain technologies and the concept of “smart” cities. The analysis of efficiency and demand of these technologies in various sectors of economy is conducted. The article considers main steps to implementation of decentralized networks in the life of modern society.

One of the basic elements of resource-saving technologies in agriculture is the concept of "current (spot, coordinate) farming," or as it is sometimes referred to as "precision agriculture" - precision agriculture. fair statement is the basis of this concept that the field is never completely homogeneous. It is always a "patchwork", where the neighboring plot of a few tens of ...

Despite the rising popularity of robotic finishing processes and various success stories from the industry, there are still some challenges to overcome to increase acceptance. This study lists questions that require further research to improve.

The article provides an overview of the modern technologies used for constructing subway tunnel sections, as well as an analysis of the methods employed at various stages of design and implementation.

The technological methods and regimes of interposers formation based on single-layer and double-layer membrane alumina plates with a system of aluminum passive elements, conductive interconnections and through transition elements built inside the dielectric body, obtained by local one-sided and two-sided through thickness anodizing using additional bipolar anodizing, were studied ...

The article establishes that in conditions of increasing competition for natural resources, the effective development of the mining industry is possible only through rational environmental management, which can be implemented through regional cooperation. It is indicated that BRICS today is an example of a successful association for the purposes of cooperation.
