Environmental safety assessment: a regional dimension
Authors: Hryhoruk P , Khrushch N , Grygoruk S 
Published: January 2021

Abstract
The peculiarities of the current stage of the functioning of the economic system of Ukraine are due to the intensification of industrial and agricultural production and, as a consequence, the operation of environmentally “dirty” technologies, their high energy and resource consumption. On the other hand, the low rate of development of the national economy, caused by internal and external destabilizing factors, leads to the use of limited investment resources in the environmental sphere, which poses a threat of environmental crisis. In this regard, the issue of assessing the state of environmental safety at both national and regional levels is becoming especially relevant. The use of modern analytical tools, in particular, methods of multidimensional statistical analysis, will help create a scientifically sound basis for the prevention and reduction of the negative consequences of the implementation of environmental threats to regional security. We proposed the use of cluster analysis technology to group regions by the level of environmental safety. The typology of regions was carried out in five clusters. The content characteristics of each cluster are presented. The absence of structural changes in the clustering of regions during the last two years was shown. The application of factor analysis methods for the same set of initial data generally confirmed the results of clustering.
Criteria for sustainable development of the system through risk assessment
Authors: Lukianova V , Golovach T 
Published: January 2021

Abstract
Based on modern developments in risk theory, it is proposed to identify two objectives of system risk management: the first (strategic) goal is focused on ensuring (maintaining) sustainable development of the system; the second (current) goal involves keeping the amount of risk within acceptable limits for the functioning of the system. Regarding the diagnosis of the activity of a particular object of study, the concept of stability can be used to characterize the stability of its position in an unstable environment. There are two areas of stability assessment: the stability of the environment and the stability of the system. Based on the considered properties of the beta coefficient, it is proposed to use the modified formulas of this indicator for diagnostics of stability and diagnostics of development within the mechanism of risk diagnostics of different levels of management. These formulas can be used for estimation of separate indicators, groups of risk factors, or risks of the object at whole. Evaluation of indicators in accordance with a certain diagnostic criterion takes into account the dynamics of values, therefore, the authors considers the calculation of the chain growth rate of indicators in index form for the relevant (identical) periods of time as the best option for standardization.

Published: January 2021

Abstract
The article is devoted to substantiating the impact of innovative activity of business entities on the indicators of sustainable development of Ukraine on the basis of the econometric modeling. It is proposed to consider this impact from the point of view of increasing the country’s gross domestic product (GDP) and the resulting factor of innovation implementations – the volume of innovative products sold. Analytical data from statistical reporting forms of Ukrainian enterprises were used by summarizing the data taken in the forms of statistical observation of the State Statistics Service of Ukraine. The models are developed based on two methodological approaches: a generalizing indicator of efficiency and effectiveness. According to the results of a study conducted by the authors, the most significant impact on the volume of GDP is exerted, in particular: among the performance indicators – the cost of innovation and the number of business entities that have implemented innovations; efficiency – the share of the volume of scientific and scientific and technical works performed in GDP. In contrast to the current models, the proposed ones provide a high level of accuracy in assessing indicators of the macroeconomic state of Ukraine, as a basis for forming an effective state policy of sustainable development. Based on the developed models, the current directions of improving and reforming the innovation ecosystem to increase the scientific potential of Ukraine are identified.

Abstract
As the main method to solve the current problem about energy shortage and environment pollution, hydrogen production via overall water splitting exhibits great prospects. The Pt-based metals were acknowledged as the optimal electrocatalysts for hydrogen evolution reaction (HER) but cannot be used commercially due to the exorbitant price. In this work, nano-porous Ni was successfully obtained through one-pot de-alloying with different atomic ratio of Ni-Al precursor (Ni25Al75, Ni15Al85, Ni10Al90). The electrochemistry testing results show that the Ni10Al90 provide a lowest onset overpotential with -1.44 V for HER. Besides, the potential decrease non-significantly after 1000 cycles of cyclic voltammetry demonstrates a considerable durability.
In situ fabrication of mesoporous NiO@ Graphite paper electrode with multilayered nanosheet wall structures for high-performance supercapacitors
Authors: Chen Yunjian , Wang Ni , Hu Wencheng 
Published: January 2021

Abstract
A mesoporous NiO@graphite paper with multilayered nanosheet wall structures (M- NiO@GP) was synthesized through a facile and low-cost hydrothermal reaction and thermal annealing process. The as-prepared M-NiO@GP electrode presents high specific capacitance (2.57 F cm−2), exhibits superior cyclic stability (92.3% capacitance retention after 10000 chargedischarge cycles) and brilliant rate capability (about 56.0% capacitance retention when the current density increased 20 times). Such high-performance capacitive behavior is attributed to the wall structure of NiO with the multilayer nanosheets, which could shorten the ion transfer distance. Meanwhile, the high specific surface area and mesoporous structure of the electrode could serve as an efficient path for OH− transfer and diffusion. The improved electrical conductivity of the electrode enabled stable and efficient electron transports and consequently improved the overall electrochemical performance of supercapacitors. Therefore, the demonstrated high conductive M-NiO@GP electrode is a promising candidate for practical supercapacitor applications.

Published: January 2021

Abstract
The limited effort in this paper is focused on studying the infrared radiation performance of Ammonium Perchlorate/ hydroxy-terminated polybutadiene(AP/HTPB) and Magnesium/ Teflon(MTV) agents, in order to compare the differences in the spectral distribution of the two agents at different doses and tube shell sizes. A FTIR remote-sensing spectrometer was used to characterize combustion flame radiation products and a Spectraline SC7000 imaging spectrometer was used to test the radiation performance of each band. The test results show that the radiation energy of AP/HTPB agents is 5-8 times smaller than that of MTV agents under the same conditions. In addition, as the mass is small (5g), the spectral distribution of AP/HTPB agent θα/β/λ. is 0.6:1:0.15, which is better than MTV agent whose θα/β/λ. is 2.3:1:0.15. But as the mass increased to 40g and the diameter of the tube shell increased to 40mm, the mass burning rate of the MTV agent increased from 0.287g/s to 4.167g/s, and the mass burning rate of AP/HTPB agent increased from 0.258g/s to 2.920g/s. At this time, the MTV spectral distribution did not change much, but the radiation energy of AP/HTPB agents is changed more concentrated in the near-infrared band, and the spectral distribution θα/β/λ. becomes 1.4:1:0.3.

Authors: Zhou Xuan , Jiang Dayong , Zhao Man , Wang Wei 
Published: January 2021

Abstract
In this work, visible-blind dual-band UV photodetectors with different interdigital electrode width were fabricated on MgZnO/ZnO bilayer film by the radio frequency (RF) magnetron sputtering technique. The devices exhibit excellent photo-response at 320 nm and 360 nm, respectively. Meanwhile, the PD with larger electrode width possesses higher photo- response and lower dark current (Id), which proved that the wider electrode is more favourable to enhance the performance of PDs. The result is originate from the stronger electric filed on the depletion region related to the electrode width. This demonstrates a facile way to fabricate dual-band UV PDs with high properties for practice application.

Authors: Du Chengbin , Zeng Fanang , Liu Bing 
Published: January 2021

Abstract
A multifunctional shear thickening fluid (MSTF) that exhibits both shear thickening (ST) effect and magnetorheological (MR) performance was prepared. The MR effect of MSTF was compared with magnetorheological fluid (MRF) when the CIP mass fraction varies from 10% to 70%. The results show that the MR effect of MSTF is higher than that of MRF obviously. Besides, the compression force and rebound force of the damper containing MSTF and MRF were tested and compared when the current was set as 0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3A. When the CIP mass fraction is less than 30%, the forces of these two kinds of materials are almost the same at any current value. And as the CIP mass fraction is more than 30%, the rebound force of MSTF is obviously higher than that of MRF.

Published: January 2021

Abstract
The smooth surface and the lack of active groups make para-aramid fiber reinforced composites have poor interfacial adhesion property, which limits their applications in various fields. In this study, aramid fiber was coated with nano-coating solution and functional groups such as epoxy and amino groups were introduced to the surface of aramid fiber to enhance the surface activity of the fiber, thereby improving the adhesion between fiber and resin. The surface composition and roughness of the modified fibers were characterized by Fouier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscope (SEM), respectively. The effect of functional groups on the interfacial adhesion properties of aramid/epoxy composites was studied by the interfacial shear strength (IFSS) and the flexural strength. aramid fiberter modification, the roughness and the polarity of the fiber were considerably improved. The IFSS reached 45.9 MPa with a significant enhancement by 27.5%; while the flexural strength increased from 240.7 MPa to 302.2 MPa, with a reinforcement of 25.6%, indicating that the study provides an effective method to achieve highiy active aramid fiber.

Published: January 2021

Abstract
The rapid development of 5G technique needs higher requirements for laminate under high-frequency condition. In this work, silicon dioxide (SiO2) surface modified by y- aminopropyl triethoxysilane (KH-550) was used as fillers to improve the dielectric and mechanical properties of polyolefin-based laminates. A relative low dielectric constant of 3.61 and dielectric loss of 3.69 × 10−3 at 10 GHz is observed for the laminate with 55 wt% K-SiO2. Moreover, the as-obtained laminate exhibits optimum mechanical properties. These results indicated that the K-SiO2 (surface modified by KH-550)/polyolefin laminate is an ideal candidate for high-frequency substrate.

Abstract
A nuclear-use ferritic-martensitic steel was irradiated by 196 MeV Kr ions. Both the low damage level area and the high damage level area were investigated by a transmission electron microscope (TEM), to reveal the irradiated microstructural features. In low damage level area ranging from surface to 6 μm depth, there were a few dislocation loops and black dots induced by Kr irradiation. The type of dislocation loops could be primarily ao<100> or ao/2<100> type. In addition, it was found that the sink effect of grain boundaries and stability of small precipitates were evident.
Ball-milling treatment of cotton fiber for optimizing its derived carbon quantum dots
Authors: Huang Ping , Xu Shunjian , Luo Yongping , Zhong Wei , Fu Haiyan , Ou Hui , Zhang Meng 
Published: January 2021

Abstract
Due to the physical force of agate balls, many cracks on the surface of cotton fiber are caused by ball-milling treatment. Moreover, ball-milling changes the structure of cotton cellulose from crystalline to amorphous. These factors help increase the contact area of cotton fiber with active water and become more reactive in the hydrothermal process. Finally, ball- milling treatment improves the yield of carbon quantum dots (CQDs), which leads to a 10% increase in the power conversion efficiency of CQDs based quantum dot-sensitized solar cells. Besides, the fluorescence intensity of CQDs is doubled without changing its other characteristics because of the ball-milling treatment. Therefore, ball-milling could be adopted as an effective green method to optimize cotton derived CQDs.
