Abstract
This article describes in detail the technology of production of low-temperature mixes (warm asphalt-concrete mixes) of type A, B and C using viscous bitumen and the method of its foaming, as well as the construction of road coatings from them in the first road-climatic zone and the results of laboratory studies of mixtures. A schematic diagram of the operation of the foaming equipment for the production of warm asphalt concrete mixes and the principle of its operation are given. The expediency of foaming viscous oil road bitumen was substantiated and confirmed by spraying an asphalt mixing plant in a mixer with a specified amount of water through the nozzles of the dispenser-dispenser of DRV-001 water. This technology is especially relevant for regions with a short duration of the construction season.
Cyclical fluctuations of the Russian economy
Authors: Tyapkina Maria , Mongush Yulia , Ilina Elena 
Published: November 2019

Abstract
The economy is subject to changes. It is characterized by the uneven nature of expanded reproduction: periods of increased production and consumption are combined with recessions and crises; new development trajectories emerge. The cyclical nature of economic development means that the main indicators and parameters of this process are wave-like. Interest in cyclical fluctuations is increasing, especially during crises. Each cycle has its own development and technological structure. New technologies and innovations spread during the upward wave of the subsequent cycle. During the downward wave, the development of the technological structure is slowing down, facing economic and social constraints caused by market limits and insufficient production efficiency. Previously dominant technologies and institutions become exhausted. It creates conditions for the development of new leading technologies, a new technological order and new social institutions. Thus, crises stimulate technological development. The article discusses Kitchin, Juglar, Kuznets, Kondratyev cycles and their regularities. The indicators used for tracking economic cycles, their turning points whose dynamics coincides with cyclical fluctuations of the economy are as follows: GDP growth rate; unemployment rate; consumer price index; investment growth rate; industrial production growth rate; gross saving growth rate; refinancing rate.

Authors: Yvarova Olga 
Published: November 2019

Abstract
The article discusses the experience of Eastern Siberia’s heavy industry evolvement starting from the Soviet times. Based on the analysis of a large number of archival documents, the process of almost all industries’ evolvement in the controlled economy is shown. That allowed the region to develop dynamically. Reconstruction and technical upload, production modernization, encouraging the initiative of workers, moral and financial incentives, improving working and living conditions were the means of enterprises’ growth and development. The idea of integrated development of territories in the form of territorial-industrial complexes (TIC) started to be implemented. Under the conditions of the changed economic paradigm, such new trends as private-public partnership in the development of deposits, increased attention to eastern neighbors, large cross-border and interstate initiatives, and increased attention to ecology began to emerge. In the context of globalization, the One Belt One Road initiative and the development of the Arctic increases the steadiness of the development of Russia and China. Much attention is paid to transport infrastructure. In general, the experience of previous generations is very useful and can serve as a source of dynamic modern development of Siberia.

Abstract
Boron-doped diamond (BDD) has important applications in the catalytic degradation of wastewater. In this paper, the TiO2 was electro-phoretically deposited onto the silicon-based BDD film by anelectrophoretic deposition method using a butyl titanate (TBOT) as the titanium source. The effect of the deposition time on the electrochemical properties of the TiO2/BDD composites was investigated. The phase and morphology were characterized by X-ray diffraction, laser Raman spectroscopy, and scanning electron microscopy. The electrical and electrochemical properties were characterized by Hall measurement system and electrochemical analyzer. The results showed that the performance of TiO2/BDD composites was significantly higher than that of single BDD electrode materials. The morphology of TiO2 films obtained by TiO2 deposition three times was better.The Hall mobility of most samples has been improved, and the Hall mobility of sample 4 increased to 213 cm2/V·s, which is 3.5 times of the single BDD materials. The electrochemical potential window of sample 4 in alkaline, acidic and neutral electrolyte are 4.6 V, 4.3 V, 4.6 V.

Published: November 2019

AbstractAn electrochemical method for multilayer graphene oxide production by anodic oxidation of graphite dispersed in sulfuric acid is proposed. The possibility of sequential dispersion of graphite during the electrochemical oxidation and hydrolysis is shown. It was established that the carbon nanostructured materials obtained are prone to agglomeration in aqueous dispersions. After sonication, the particle size of the oxidized graphite was found to significantly decrease with the formation of the multilayer graphene oxide. It was elucidated that the structure of the obtained material consists of multigraphene planes with a thickness of 0.01-0.10 µm, and the pore size is 1-10 µm. The possibility of using the graphene oxide to produce polymer composite materials and composite electrochemical coatings is considered. Regarding the kinetics of the epoxy composition curing, it was observed that the graphene oxide affects the structure formation, which was indicated by an increase in the gel formation duration from 45 to 64 min and curing from 53 to 78 min, with an increase in the maximum curing temperature from 105 to 116 °C. Through the method of thermogravimetric analysis, it was established that the introduction of the graphene oxide reduces the thermal stability of the epoxy composites, but provides increased Vica heat resistance from 100 to 125-158 °C. The width of the passive state area for the nickel-graphene oxide composite electrochemical coating was found to be 1.32-1.40 times higher than that for the pristine nickel coating.

Published: November 2019

Abstract
When combining special mechanochemical processing of graphite in high-speed and planetary ball mills and heat treatment, it was revealed that condensed graphene oxide is formed, and a nitrogen-containing carbon phase is synthesized. Melamine was used as the material for introducing nitrogen into the system; during the heat treatment it releases ammonia. Besides, it improves the process of compaction of graphite powders into workpieces in the production of refractive X-ray optics. The mechanochemical synthesis of graphite with melamine (not more than 1 wt.%) and two-stage annealing at 360 and 450 °C leads to the formation of some forms of they lead to the formation of graphene oxide and a nitrogen-containing carbon phase. X-ray studies revealed the appearance of peaks that can be attributed to peaks of graphene oxide and carbon nitride. The formed condensed carbon compounds with nitrogen and oxygen are characterized by natural aging.

Abstract
A comparative study of two processes was carried out: frontal polymerization of 1, 4-diethynylbenzene, proceeding as a result of high-temperature initiation under increased nitrogen pressure (P = 2–6 MPa), and ammonium perchlorate burning in the same conditions. It was shown that the linear rate of thermal transformations of 1, 4-diethynylbenzene is close to the linear burning rate of the energetically saturated compound. The structure of the carbon material obtained as a result of thermal transformations of 1, 4-diethynylbenzene was investigated using elemental analysis, Raman spectroscopy and scanning electron microscopy.

Authors: Zakharova O , Kolesnikova E , Kolesnikov E , Baranchikov P , Strekalova N , Gusev A 
Published: November 2019

Abstract
This paper focuses on the effects produced by GO-Ag and GO-CuO composite materials on microclones of hybrid white poplar and aspen (Populus alba x Populus tremula), hairy birch (Betula pubescens), crack willow (Salix fragilis), red oak (Quercus rubra) and scots pine (Pinus sylvestris) during their adaptation to greenhouse environment. The study revealed a positive effect of microclones treatment with GO-CuO and GO-Ag solutions at a concentration of 3 μg/l. The number of surviving and adapted microclones increased considerably, as did such parameters as the height of the plantlets, the number of leaves and the plantlets condition on a 1 to 5 scale. Photosynthetic activity was high in the white poplar and aspen hybrid, in birch, willow and pine. At the same time, in oak, the maximal stimulation of biomorphological parameters was accompanied by the decrease in photosynthetic activity. GO-Ag solution at a concentration of 4.5 μg/l produced an inhibitory effect on all the studied species except red oak.

Published: November 2019

Abstract
Metal nanoclusters (NCs) with atomic precision are receiving significant attention because of their widespread applications in the field of energy-related materials, sensing and biomedicine. In this work, luminescent Au nanoclusters (NCs) are synthesized from Au nanoparticles (NPs) by core-etching process in presence of excess glutathione (GSH) ligand. Electrospray ionization (ESI) mass spectrometric study suggests the formation of polydisperse Au6 and Au8 NCs at elevated temperature (70 °C). The HOMO-LUMO band gap of Au6 and Au8 clusters are calculated from optimized structure. The photoluminescence maximum of as-prepared Au NCs is observed at 421 nm after excitation at 340 nm with 4.20% quantum yield (QY). Lifetime of the NCs is found to be 0.57 ns in excited state, which arises because of electronic transitions from low-lying d-bands to excited state sp bands of core-state only. Moreover the luminescence intensity of as-prepared Au NCs is found to be very stable both in acidic and basic medium. The synthesis of luminescent Au NCs from non-luminescent plasmonic Au NPs is beneficial for various applications such as sensing, biomedicine, and light emitting devices.
Microstructure and properties of Fe–Cr–Ni alloy coatings on T10 steel by laser cladding
Authors: Zhou Lei , Liu Yanhui , Li Zhiwei , Zhu Lingjie , Li Yongjiu , Xiong Anhui 
Published: November 2019

Abstract
In the present study, Fe–Cr–Ni alloy coatings were produced by laser cladding using the blending powder of Cr and Ni on the surface of T10 steel. The composition of phase and microstructure were analyzed by scanning electron microscope (SEM) and x-ray diffraction (XRD). The microhardness and corrosion resistance were investigated. The Fe–Cr–Ni cladding coatings composed of austenites and a few eutectic ferrites. And the content of eutectic ferrite in the grain boundary decreased with the decreasing Cr/Ni ratio of the blending powder. The Creq/Nieq ratio and the ferrite number (FN) of the coatings confirm that the solidification process was the AF mode for the Fe–Cr–Ni cladding coatings. The average microhardness value of Fe–Cr–Ni coatings was about 380HV0.2 and the Cr/Ni ratio of the blending powder was not an obvious effect. The corrosion resistance of Fe–Cr–Ni alloy coatings which was significantly superior to T10 steel decreased with the decreasing Cr/Ni ratio of the blending powder. This research exhibits that the Fe–Cr–Ni coatings and laser cladding processing have a potential engineering application value on hypereutectoid carbon steel.

Abstract
Zinc sulphide doped with nickel (Ni:ZnS) has many applications in different fields like materials science, electronics, optics, and other industrial applications. Experimentally, a large variety of methods have been developed for Ni:ZnS synthesizing, where the chemical synthesis with capping agent is most successful, but has disadvantages like purity and the low performance. In addition, since there is not also much theoretical information about its features, the electronic and optical response of Ni:ZnS were studied, both experimentally by x-ray diffractometry (XRD), transmission electron microscopy (HR-TEM), and x-ray photoelectron spectroscopy (XPS) and theoretically by means of the density functional theory (DFT) calculations, giving an unified understanding of the electrooptical performance of this compound. In the same way, the importance of the inclusion of Ni impurities in the structure was studied and analyzed by the inclusion of a Hubbard potential in the calculations. We found that the optimal U value for Ni atoms is 4 eV in agreement with experimental results obtained by XPS. The dielectric function (ε
2) for pure and doped systems showed that the influence of the Ni atom is mainly given in the range of low energy regions (E < 6 eV), where the new peaks are associated to transitions that include the impurity band states.
Efficient flexible perovskite solar cells based on a polymer additive
Authors: Lan Yangjie , Wang Yang , Song Yanlin 
Published: November 2019

Abstract
The rapid development of flexible perovskite solar cells (FPSCs) has attracted more and more attention. The application of FPSCs is largely in thrall to the fragility of perovskite crystals and quality of perovskite films caused by the inherent nature and uncertain grain size of perovskite. A polymer additive as an efficient strategy is utilized to restrict the fragility and improve the durability of FPSCs. In this work, we use polycaprolactone (PCL) as a polymer additive to achieve the grain boundary regulation (improving the grain size) and the desirable mechanical strength of FPSCs. A champion device based on glass/indium tin oxide (ITO) achieves high photoelectric conversion efficiency (PCE) (14.49%), which is ∼37.7% higher than that of the pristine film (10.52%). While the efficiency of FPSCs also retains 9.11%, which is 90% of the initial PCE (10.12%) after 300 bending cycles. Importantly, the PCL as a polymer additive shows great potential for future applications in wearable electronics.

Published: November 2019

Abstract
Here we describe and experimentally confirm the localization of charged microparticles outside the area of a radio-frequency Paul trap. We consider the nonlinear effective potential formed by the trap, treating the field independently for different electrodes of the trap. To approach the proposed model to reality, we also consider the nonlinear effects originating from the viscousity of surrounding medium. Proposed approach allows to conduct an analytical description of the effective potential and define quasi-equilibrium points both inside and outside the trap. Predictions of the proposed model are in full compliance with obtained experimental results.
