Abstract
This paper presents an analysis of the application of new technologies in the design of thermoelectric cooling systems, presented the results of the comparative analysis of classical thermoelectric system and the thermoelectric system with the spatial orientation of the heat transfer sides. New thermoelectric systems are beginning to compete with traditional ways of energy transformation up to several hundred watts. To extend the range of applications of thermoelectric systems, it is necessary to use new design methods and new design solutions that will more effectively convert heat losses into useful energy for future use. This paper presents the results of a comparative analysis of conventional thermoelectric module and the thermoelectric module with the spatial orientation of the parties. It is shown that the efficiency of the thermoelectric module with the spatial orientation of the parties in the current in 4A 36% higher compared to the classic thermoelectric module and 43% higher when the current is 8A. The results of the research have shown that the efficiency of the thermoelectric modules to a greater extent influence not electrophysical characteristics of thermoelectric junctions, and the technical decisions when designing and designing. Studies have shown that further work to increase the efficiency of thermoelectric systems should be conducted in the field of improvement of structure of the thermoelectric modules. Using the known topology emitted or absorbed heat from the thermoelectric module can be moved to side to distribute it over a larger area or concentrate on a smaller area. With the increase of its efficiency, thermoelectric modules can compete with traditional heat pumps in the field of higher capacity and will be able to expand your range of applications.

Published: November 2019

Abstract
Traditional experimental methods always cost a lot but produce little when designing and developing new kinds of materials, especially for coating materials. However, with the assistance of machine learning, it is possible to predict the performance of a specific coating without preparation or simulation, which makes the design of material more efficient. In this study, machine learning was introduced to assist the design of resin matrix composites coating with ablation resistance. A structured method for engineering data in the material field was approved. Based on this method, the data from laboratory records and Lange’s Chemistry Handbook were collated into one operational database. All the 190 sets of data were used to train the artificial neural network (ANN) regression model to predict the back-surface temperature of the substrate for specific coating under given ablation condition. The mean absolutely percentage error (MAPE) of the model is 7%. Concerning the characteristics of the material database, a feature engineering method, which combines the Pearson correlation coefficient and random forest (RF) algorithm was performed to identify the main controlling factors of the service performance of the coatings.

Published: November 2019

Abstract
CrSiN coatings have been successfully deposited on the surface of GH169 alloy by closed filed unbalanced magnetron sputtering (CFUBMS). The microstructure, chemical and phase composition of the coatings were characterized by SEM, EDS and XRD, respectively. The mechanical properties of the coatings such as microhardness and adhesion strength were measured by indentation method and scratch method, respectively. The isothermal oxidation behavior of CrSiN coating at 700°C was investigated using thermogravimetric analysis. Results show that Cr, Cr2N and CrN coexisted in the dense as-deposited CrSiN coating without Si-containing phases; the coating surface was rough and a small amount of oxide (Cr2O3 and SiO2) was formed on the surface after oxidation at 700°C for 24 hours. The isothermal oxidation result suggested that CrSiN coating possesses excellent oxidation resistance at 700°C. It is considered that the good oxidation resistance of CrSiN coating itself and the formation of dense protectiveCr2O3 and SiO2 films are primarily responsible for the good service performance during the oxidation process at 700°C.

Published: November 2019

Abstract
Silicon carbide (SiC) films were synthesized on graphite substrates using silicon nitride (Si3N4) as silicon source at 1850°C, 1950°C, 2050°C and 2150°C, respectively. The characteristics of the synthesized films were analyzed by X-ray diffraction and scanning electron microscopy. The results show that the synthesis reaction can take place above 1850°C, and the SiC films were β-SiC. With the increase of temperature, the size of SiC particles increases, and when the soaking time is too short, the SiC particles are connected in a large area. Through the analysis of the films synthesis process, it is inferred that the growth of the SiC films belongs to the gas-solid growth mechanism.

Abstract
An effective accelerated synthesis procedure of a carbon material based on chitosan via infrared pyrolysis was developed. Infrared radiation heating allows to shorten preparation time significantly. It takes only 2 min of the residence time at 800 °C for complete carbonization of the polymer. The chemical transformations in chitosan during infrared pyrolysis depended on temperature were studied. The formation of C=C–C=N and C=C–C=C conjugated bonds at a low-temperature stage of the carbonization process was demonstrated. It was revealed that the main product of the chitosan pyrolysis at 600-800 °C represents a graphite-like carbon material in the form of carbocyclic structures.

Authors: Sldozian R J , Mikhaleva Z , Tkachev A 
Published: November 2019

Abstract
The paper presents the results of studies on assessing the effectiveness of the modification of lightweight concrete with nanostructures. The results of these experimental studies show that the introduction of additives based on nanostructures, such as dispersions of carbon nanotubes and silica nanoparticles, improves the physical-mechanical characteristics of lightweight foam concrete (LWFC), even at low additive concentrations. As a result of chemical and physical interactions, nanosilica (NS) accelerates the pozzolanic reaction between cement and nanosilicate in the concrete mixture, filling the gaps. CNTs affect the hydration process and effectively increase the grain growth of calcium silicate hydrate (C-S-H). The presented experimental studies not only demonstrate the possibility of modifying construction materials with nanostructures in order to improve the physical and mechanical properties of the LWFC but also provide potential modification mechanisms that help in designing and manufacturing high-tech lightweight concrete of various compositions.

Published: November 2019

Abstract
The present paper considers the efficiency of using carbon nanotubes (CNTs) functionalized by titanium stearate groups for modifying of polyethylene and polypropylene. For this purpose, the strength characteristics, Shore hardness, thermal diffusivity and conductivity of the obtained nanocomposites were determined. The weak effect of the CNTs (0.01-1.5 wt.%) on the values of thermal conductivity coefficients and thermal diffusivity was revealed. It was found that compared to the unmodified matrix, nanocomposites containing 0.01-0.1 wt.% of the titanium stearatefunctionalized CNTs demonstrate, an increase in the Shore hardness by 12.5-14.5%, a decrease in the weight wear by 54.2%, and the daily water absorption - to the values below the threshold of sensitivity of the standardized method of determination. The functionalization by the titanium stearate groups made it possible to reduce the CNTs mass fraction in the composition of polyethylene and polypropylene composites by more than 10 times compared with the pristine nanotubes.

Published: November 2019

Abstract
The present paper study electrochromic films of nanocrystalline tungsten oxide (VI) by electrochemical impedance spectroscopy. Electrochromic films were obtained using the simplified technique of deposition of tungsten (VI) oxide from an aqueous dispersion on surface of transparent electrode In2O3. To obtain a uniform composition, the aqueous dispersion was treated with ultrasonic radiation, while the average particle size of tungsten oxide in the dispersion volume was from 30 to 70 nm. The prepared films had an amorphous structure and a crystalline structure was obtained by pyrolysis at a temperature of 250, 300, and 400 °C corresponding to different samples. The obtained nanocrystalline films were studied by electrochemical impedance spectroscopy in the frequency range from 1 to 106 Hz with an amplitude of an alternating voltage of 10 mV to determine the effect of temperature on the impedance of the films. The analysis data allowed us to determine the dependence of electrical conductivity on the volume of grains and the boundaries between crystals on the influence of temperatures on the structure properties of electrochromic films of nanocrystalline tungsten (VI) oxide.
