Pore Water Characterization of the Tight Rocks of Bazhenov Formation Using the Water and Salt Extracts
Authors: Kazak E S , Sorokoumova Ya V 
Published: April 2020

Abstract
The paper presents the results of the pore water composition investigation of tight shales of the Bazhenov Formation rocks of Western Siberia, obtained by integrated interpretation of the experimental data of the water and salt extracts. The two methods of cation exchange capacity (CEC) measurement were applied – Pfeffer and Hexaamminecobalt trichloride method. Both of them showed similar results. CEC varies from 3.45 to 4.53 meq/100 g by Pfeffer method and from 3.51 to 4.35 meq/100 g by Hexaamminecobalt trichloride method. Ca, Na, Mg, K form exchange complex of all studied core samples. According to interrelation (rNa+rK)>rCa the exchange complex type is marine and was inherited from the composition of the paleobasin seawater. It was found that water extract composition depends on the core mineral content, except chlorine, which originates from the pore water. Using the thermodynamic modelling in PHREEQC program, next ratio of exchange cations was found - Na (up to 91%), Mg (up to 5.6%), Ca (up to 2 .6 %) and K (up to 0.8%). According to the calculation using the water extracts results, the pore water salinity changes from 1.23 to 21.96 g/L.

Authors: Mamedova L , Gogolukhina M 
Published: April 2020

Abstract
The world gas consumption, as well as the needs in its transportation are growing constantly nowadays. Gas transportation in a liquid form has become a strong competitor for traditional pipelines. LNG can be transported by different transport means by sea, rivers, roads, railway. Tank-containers allow to transport LNG without its reloading into other tanks due to universal container construction. Traditional tank-containers are heavy, have limited lifespan and not sufficient durability. The innovational membrane tank-containers made of aluminum alloy with low scandium content solve the majority of the aforementioned technical problems. They provide the highest level of safety for dangerous cargo transportation, longer operation period and lower weight of the construction. The last two parameters influence positively the economic efficiency of using innovational tank-containers in multimodal LNG-transportation. The research compared the traditional steel and innovational aluminum-scandium tank-containers used in automobile and railway LNG-transportation. The innovational ones are more perspective for investment due to lower operational costs and lower depreciation rates. As an option the manufacturing could be also organized at shipbuilding yards, which are familiar with the technology of LNG-tankers construction. It allows to start new production without significant initial investments, to broaden the market and to increase the level of capacity usage.
An Integrated Solution to Urban and Sea Waste Management Systems: Using Axiomatic Design to Discuss Urban Development Risks
Authors: Dunichkin I V , De Souza C Bleil 
Published: April 2020

Abstract
The problems of preserving the natural environment of the Arctic Ocean and cleaning the Great Pacific Garbage Patch can be used to enrich business activities in the Primorsky Territory of the Russian Federation and the Eastern Sector of the Arctic. In this regard, the infrastructure of the ports of the Northern Sea Route could be seen as a new vector of development, not only taking into account the requirements for eliminating accidents and emergencies from shipwreck and oil spills, but also providing adequate infra-structure for waste treatment. This would connect the underused existing waste management infrastructure with the cleaning of parts of the Great Pacific Garbage Patch. The unstable composition of garbage from the Pacific Ocean and the waters of the Northern Sea Route require a consistent multi-level system of water and waste treatment centers using not only ships and ports, but also offshore structure. The article discusses a framework for design solutions for the urban development of the Vladivostok Commercial Sea Port and approaches to maximize the use of waste management facilities in Russky Island, using Axiomatic Design.

Authors: Ibragimov A M , Vachnina T N , Susoeva I V 
Published: April 2020

Abstract
Thermal insulation boards from unused spinning waste of linen and cotton fibers and soft wood waste have increased combustibility, like all composites with plant filler without mineral binders. To increase the fire protection of composites with plant filler, the use of flame retardants is necessary. The introduction of the composition of mineral combustion inhibitors - sodium carbonate or aluminum trihydrate allowed to reduce the combustibility of the material. The degree of damage by weight during combustion in the “ceramic box” of material samples from unused waste from the production of cotton and linen fibers and wood chips decreased by 1.3 … 3.2 times depending on the type and proportion of flame retardant additives and the type of plant filler.

Abstract
This paper presents the unique spreading process of droplet on dielectric barrier discharge (DBD) actuator periodic plasma surface. High-speed camera is used to capture the droplet spreading process. We use image processing to handle the massive droplets image data. Results show that droplets have more spreading time and much less oscillation cycles on periodic plasma surface, and the spreading diameter is larger while the apex height is lower. Furthermore, the effect of periodic plasma density is studied. And it is revealed that when plasma density increases in certain density range, the maximum and final spreading diameters increase, while the apex height of droplet in stabilization phase decreases.

Abstract
In order to discuss the effect of negative bias on the structure and properties of MoS2-Ti composite films on titanium alloy surface. In this paper, MoS2-Ti solid lubrication films were deposited on titanium alloy surface by unbalanced magnetron sputter. The effects of negative bias on the structure and properties of MoS2-Ti solid lubrication films were discussed. The morphology, phase, hardness, friction and wear resistance and wear mark morphology of solid lubricating film were analyzed and tested by scanning electron microscope, XRD, microhardness tester, friction and wear tester and surface profilometer. The results shows that wwhen the negative bias voltage was -150V and -200V, the structure of MoS2-Ti films is compact and the bonding with the substrate is compact. With the increase of negative bias voltage, the hardness of the film increases gradually. The wear rate of the films prepared at -150V bias voltage is the lowest, which is 2.2×10−17mm3/(N×m). The MoS2-Ti composite films deposited on the surface of titanium alloy exhibit excellent tribological properties with low friction and wear resistance, which effectively improves the surface friction and wear properties of titanium alloy.

Authors: Liu Yang 
Published: April 2020

Abstract
Bi2Te3 thin film samples are prepared by magnetron co sputtering. The samples are annealed in a nitrogen atmosphere and were treated at different temperature for 2 h. Effects of annealing temperature on the structure and thermoelectric properties of Bi2Te3 are studied in detail. As the annealing temperature increases, the Te element on the surface begins to volatilize, and some Te elements precipitate and crystallize on the surface, resulting in a decrease in the Te element in the Bi2Te3 thin film. When the annealing temperature is 350 ° C, the power factor of Bi2Te3 film reaches a maximum of 0.21×10−3 Wm−1K−2.

The results indicate that the thermal degradation of CZS-2 involves three steps, the thermal degradation of CZS-1 involve four steps. The thermal decomposing temperature <430°C, thermal stability of CZS-2 was worse; while the thermal decomposing temperature >430°C, the relationship was just opposite. With the heating rate increasing, thermal decomposing temperature of CZS-1 and CZS-2 were increased gradually. The thermal degradation kinetics of CZS-1 and CZS-2 were studied by Kissinger’s method. It was found that thermal degradation activation energy of CZS-1 and CZS-2 were 43.6 kJ/mol and 30.7 kJ/mol at the first and second steps, respectively.
