Published: December 2019

Abstract
The results of the research of the conditions of the purification of the natural graphite with the usage of the processes of the hydrodifluoride technology are given. The interaction of the major impurity elements of the concentrate with NH4HF2 resulting in the formation of the complex fluorine ammonium salts and simple fluorides is established to occur during processing of the graphite concentrate with ammonium hydrodifluoride. Conducting the fluoridization with usage of 20% of surplus of NH4HF2 has been found to allow reaching the complete fluoridization of the impurity components which are present in the graphite. The complex fluorine ammonium salts and the fluorides of alkaline metals have appeared to be removed from fluoridated concentrate by means of the water leaching.

Published: December 2019

Abstract
A method for forming thin films of the Cu2SnS3 compound homogeneous in phase composition for use in solar cell devices is proposed. The Cu-Sn alloy layers deposited by thermal spraying in vacuum were annealed in sulfur vapor in a graphite chamber of the quasi-closed volume type. Using X-ray phase analysis, the optimal conditions for the formation of Cu2SnS3 films homogeneous in phase composition were found: annealing temperature 450 °C, sulfur vapor pressure ∼ 0.2 torr. The sulfide layers obtained in this way in their elemental composition correspond to the Cu2SnS3 compound stoichiometry. Cu2SnS3 films have an optical band gap of 1 eV, and the absorption coefficient in the visible region of the spectrum is 2·105 cm –1.

Published: December 2019

Abstract
Solid electrolytes are widely used in electrochemical devices. Among these materials, electrolytes with the lithium-ion conductivity can be used in high-energy lithium and lithium-ion power sources. The perspective Li6.75La3Zr1.75Nb0.25O12 solid electrolyte was synthesized by modified sol-gel synthesis method using the sparingly soluble Nb2O5 as one of the initial compounds. The influence of pressure and final sintering temperature on phase composition, density and lithium-ion conductivity was studied. Solid electrolyte obtained at 1150°C was single phase and had a cubic structure with the space group Ia-3d. Thus in the presented work, the cubic modification of Li6.75La3Zr1.75Nb0.25O12 was obtained by thermal treatment for 1 h at 1150°C (versus 36 h at 1200°C in the literature). Moreover at this temperature the samples had the highest density and total lithium-ion conductivity (3.9·10–5 Scm–1 at 25°C). According to the SEM study ceramic samples have a dense structure with a particle size ∼1-3 μm. Solid electrolyte was also obtained by isostatic pressing at a pressure of 500 MPa but the values of density and total lithium-ion conductivity were comparable with that of the samples compressed statically.

Published: December 2019

Abstract
Dense oxygen transport membranes (OTMs) made from mixed oxygen ionic and electronic conductors (MIEC) have attracted intense research interest owing to their unmatched advantages on pure oxygen production, oxygen-fuel combustion and oxygen-related catalytic processes over traditional techniques. As one kind of the most-studied membranes, cobalt-containing membranes have unsatisfied thermal stability, though the oxygen permeability of these membranes is generally excellent due to the existence of cobalt. However, in situ forming CoO phase which were observed in the cobalt-containing membranes prepared by low pressure plasma spraying-thin film technology (LPPS-TF), were found to exhibit a remarkable stabilizing effect in the preliminary work. As one of the main premises to reveal the stabilization mechanism of these island CoO phase, their formation mechanism were studied in the first place in the paper.

Abstract
The microstructure, composition, mechanical and thermoelectric properties of samples cut from different sections of a rod with a diameter of 20 mm, a length of 300 mm, extruded from a briquette pressed from granules obtained by crystallization of Bi0.4Sb1.6Te3 solid solution in water were investigated. It was established that the composition of the samples does not change along the length of the rod, while there is a small amount of the second phase (tellurium-based eutectic) is observed both at the beginning and at the end of the rod. A compression test at room temperature showed that the ultimate strength of specimens cut from the end of a rod is ∼10% higher than that of specimens cut from the middle Thermoelectric parameters (electrical conductivity, thermal conductivity, Seebeck coefficient and thermoelectric figure of merit) at room temperature of samples cut from different areas of the rod were σ = 814 ± 55 S/cm, k = 13.2 ± 0.3 W/cm K, α = 234 ± 5 µ V/K, ZT = 0.93-1.12. Measurements of the thermoelectric properties of these samples in the temperature range of 100-600 K showed that the intrinsic conductivity occurs at temperatures above 450 K. The maximum thermoelectric figure of merit ZT
max = 1.2 ± 0.1 was obtained at a temperature of 340 K.

Abstract
Investigation concerns the method of preparation of low-alloyed molybdenum single crystals directly from molybdenum rods and wire, rod or foil containing the appropriate alloying metal, excluding the stage of pre-fusion of the components in an arc furnace, which is more economical than traditional method. In this way Mo-W, Mo-Ta (1,5 wt.% alloying elements of each) and Mo-Re (2 and 3 wt.%) single crystals were prepared by electron-beam zone melting. Authors discuss in more detail the structure and structural parameters of prepared single crystals. Some structural features of Mo-2 wt.% Re and Mo-3 wt.% Re single crystals are explained. Moreover the coefficient thermal linear expansion (CTLE) was measured for Mo-Re single crystals. As shown the proposed method ensures the preparation of single crystal even in single stage melt. The structural imperfections may be removed by following re-melting.

A multiwavelength study of the Sunspot of active region which leads to X 17 solar flare
Authors: Mohd Norsham Nur Amira , Sharizat Hamidi Zety 
Published: December 2019

Abstract
This paper focuses on the study of active region (AR) 486 from the 171 Å wavelength in conjunction with solar radio burst data from the e-CALLISTO. This active region produced quite a strong solar flare with the X 17 class on 28th October 2003. The intense solar flare was detected by the CALLISTO system as the type III solar burst. Another data for this study were collected from the online database of Solar Monitor and Space Weather Live website where they provided the data from NOAA and SDO/AIA publicly. The study of the solar flare event was done by observing the sunspot for the past six days to see the changes in the magnetic field of the active region 486 and compared it to the solar radio data for the nature of the solar flares. The active region 486 alone had a sunspot number of 74 which is quite high, hence it produced a flare with the solar wind speed of 800 km/s and a solar radio burst type III with the storm type. The frequency drift rate for the solar burst was 2.15 MHz/s which proved that this type III is a fast drift burst. It was also recorded that the coronal mass ejection followed this solar flare event with the speed of nearly 2000 km/s and directed toward the Earth which then produced intense geomagnetic storm on the Earth the next day.

Automatic code parallelization for data-intensive computing in multicore systems
Authors: Subramanian Ranjini , Zhang Hui 
Published: December 2019

Abstract
A major driving force behind the increasing popularity of data science is the increasing need for data-driven analytics fuelled by massive amounts of complex data. Increasingly, parallel processing has become a cost-effective method for computationally large and data-intensive problems. Many existing applications are sequential in nature and if such applications are ported to multi-processor systems for execution, they would make use of only one core and the optimal usage of all cores is not guaranteed. Knowledge of parallel programming is necessary to ensure the use of processing power offered by multi-processor systems in order to achieve better performance. However, many users do not possess the skills and knowledge required to convert existing sequential code to parallel code to achieve speedups and scalability. In this paper, we introduce a framework that automatically transforms existing sequential code to parallel code while ensuring functional correctness using divide-and-conquer paradigm, so that the benefits offered by multi-core systems can be maximized. The paper will outline the implementation of the framework and demonstrate its usage with practical use cases.

Abstract
In recent years, the amalgamation of renewable energies into combined cooling, heating and power system (CCHP) become a popular research in energy field. In order to improve the energy utilization of renewable energies integrated the CCHP (RECCHP) system, it is necessary to optimize the operation and component capacity in the RECCHP system. A multi-objective optimization model characterizing the system daily operation cost, daily carbon dioxide emission, and primary energy saving rate is established. Considering each objective function, Simplified Swarm Optimization (SSO) is applied as a single objective optimization problem to find the best capacity of components and operation of the system. Further, normalize three objective respectively and use Analytic Hierarchy Process to get weight for each objective. Transform the multi-objective optimization problem into a single objective optimization problem. Finally, taking a historical weather data in winter of Kinmen Island, Taiwan, as a case study, solve the problem with SSO, and the experiment results are compared with traditional energy systems. The results show that the RECCHP system is better than traditional energy systems among economic, environmental and energy aspect.
