Authors: Dmitrieva N G 
Published: November 2021

Abstract
At present, there is a huge amount of industrial waste accumulated in Russia, polluting the environment and covering large areas. The greatest impact on the environment comes from open-pit or quarry mining. Mining activities result in huge quantities of rock being brought to the surface and hence produce significant amounts of waste is generated, which has a negative impact on the natural environment. This is also typical for the Republic of Buryatia, where one of the main environmental problems is the formation of waste from both operating and shutdown mining enterprises. In this article we have analysed consequences of mining on natural environment using examples of operating and shut-down mining enterprises in Buryatia. We also gave typical examples of mining enterprises that have the strongest impact on the ecological condition of the territory.

AbstractIn this article we consider the main problems associated with the anthropogenic load and underdeveloped tourist infrastructure on Olkhon Island. Large numbers of tourists arrive on the island uncontrollably, complicating the operation of transport infrastructure and putting pressure on the landscape. In this regard, there is a need to develop a way to control the tourist flow. Olkhon Island is a protected area, the natural resources of which are protected by many laws and restrictions. At the same time, restricting tourist entry is not possible due to the fact that tourism is the main way for many residents to earn money. In this article, a comprehensive analysis of the current state of the tourist infrastructure on Olkhon Island is made, the main problems are identified, and promising approaches and possible solutions are outlined. We considered the main methods for registering tourists, which are used both in the Russian Federation and in tourist centres in many countries. It was proposed to create an electronic resource that will not only provide up-to-date information about Baikal, Olkhon Island and tourist services, but also allow electronic registration of tourists in this area.

Abstract
High-density crystalline silicon modules have recently invoked large interest in PV industry due to its higher efficiency. However, high-density stacking of cells in this kind of module may have additional reliability problem, which might cause higher power loss during outdoor operation. Modules based on half-cut cells have been widely studied due to their higher power output compared with modules based on full cells. When a cell is half cut, its current level is half reduced. When it is 1/3 cut, its current level is decreased by 2/3. However, high-density modules based on 1/3-cut cells have rarely been studied. Therefore, in this work, damp heat (DH), thermal cycle (TC), UV irradiation and humidity freezing (HF) test were utilized to study the power degradation performance of these high-density modules fabricated with 1/3 cut cells. The obtained results show that these novel high-density modules with negative space between 1/3 cut cells have good reliability in various environmental conditions.

Abstract
In order to avoid the resonance of the bench and the laboratory floor, it is necessary to carry out vibration analysis and dynamic design on the motor test bench. Firstly, the lightweight target and the constraint conditions related to the rigid body modal frequency and elastic modal frequency of the platform are set, and the structure of the platform is optimized. Then, the three-dimensional model of the whole bench is built and the finite element is meshed to carry out modal analysis. The optimized modal analysis results show that the natural frequencies of the designed bench will not be excited by various vibration excitation forces at the set speed of motor test, the vibration isolation rate of the lower bracket reaches more than 52% (except that the vibration isolation rate of the lower bracket is 36.30% at 1000 rpm), which effectively eliminates the resonance problem between the bench and foundation during motor NVH test, and the normal performance of motor and NVH test can be effectively ensured.

Reduction of tar from biomass gasification using a dielectric barrier discharge reactor
Authors: Lim M , Alimuddin Z 
Published: November 2021

Abstract
A non-thermal plasma reactor was used to investigate its effectiveness in reducing the by-products from biomass gasification. Biomass is used for generating heat and power through gasification, which is a process of converting solid fuel to gaseous fuel at temperatures of 700 to 900 °C by operating a reactor in sub-stoichiometric conditions. This gas mixture can be utilized for liquid fuel synthesis or for fuel cells. However, the by-product of gasification consists of tar, which consists of oxygenates, ringed-aromatics, phenolic compounds, and polyaromatic hydrocarbons (PAH). Depending on the composition, the condensation temperature can be as high as 450 °C, fouling downstream equipment. In this study, a dielectric barrier discharge (DBD) reactor with a coil as the inner electrode was used to reduce toluene, a model tar compound. Toluene was injected into a mixing chamber that was heated to 900 °C, evaporating the toluene, and is entrained by nitrogen into the DBD reactor. High voltage is injected into the DBD reactor to initiate ionization, decomposing the toluene into lighter hydrocarbons. A sampling bottle submerged in an ice bath collects the residual toluene, and the resulting decomposition rate is as high as 70%.

Abstract
The concept of sustainable and green solvent has always highlighted in the field of energy and environmental science. The synthesis and application of natural-based Low Transition Temperature Mixture (LTTM) as a novel and green solvent for the lignocellulose biomass pre-treatment such as delignification of Oil-Palm Empty Fruit Bunch (EFB) have been greatly emphasized. In this present work, the investigation of LTTM efficiency as green solvent in delignification process was conducted using both theoretical and experimental studies. Initially, screening of solvation properties of different types of hydrogen bond acceptor (HBA) and predicted hydrogen bond donor (HBD) for synthesis of LTTMs was conducted using conductor-like screening model (COSMO-RS) software and formation of hydrogen bonding was evidenced using NMR spectroscopy analysis. Three types of HBA namely sucrose, choline chloride and monosodium glutamate were mixed with malic acids as HBD and their charge density distribution on the surface was determined through sigma profile (σ). The COSMO-RS results determined the σ profile of pure component malic acid to be 11.42, sucrose to be 25.37 and the total value of σ profile for mixtures is 14.19 as the best combination of LTTM composition compared to LTTM from choline chloride and monosodium glutamate (MSG). The reliability of the COSMO-RS predictions data was correlated with Nuclear Magnetic Resonance (NMR) analysis through determination of peaks with chemical shifts hydrogen bonding that suggested existence of potential interaction between malic acids and sucrose has occurred.

Published: November 2021

Abstract
The deficiency of natural resources and serious climate change have driven the global community to optimize energy planning using various process integration approaches. The inter-entities energy planning that allows internal sharing of resources poses a great potential to enhance energy planning. It is believed that the effective management of such relationships is crucial to gaining collaborative synergies, which provide economic benefits and minimize environmental impact. The developed inter-collaborated energy sharing model gives a handy lens to evaluate the effectiveness of the suggested inter-entities collaboration and how it provides economic benefits for the involved “players”. To demonstrate the economic viability of the inter-entities’ energy planning, an energy sharing model is developed and applied to an illustrative case study that involved two entities. The results show that, when energy sharing is enabled, the involved entities can reduce their monthly electricity bill by 16.72 % (MYR 14940.73) for entity 1 and 14.29 % (MYR 14218.50) for entity 2, with a 20 % carbon emission constraint limit.

Published: November 2021

Abstract
A green composite made up of renewable and recyclable materials has become one of the advanced material’s attractive topics. The smooth fly ash surface used in the green composite for flame retardancy enhancement are hard to bind with hydrophobic polymer. Thus, the surface modification of this filler is needed to increase its surface roughness and pore size to be more compatible with its polymer matrix. In this research study, the alkaline pre-treatment of fly ash has been performed by using sodium hydroxide solution (NaOH) with various concentrations (5 w/w%, 10 w/w%, 15 w/w%, 20 w/w%). For pore size and morphological of the filler’s evaluation, few analyses such as Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX), Barret-Joyner-Halenda (BJH) and Brunauer-Emmett-Teller (BET) pore size and volume analysis were conducted. Treated fly ash with 20 w/w% sodium hydroxide concentration gives the better morphological structure in terms of pore diameter, volume, area and high composition of aluminium, silicon with lower calcium and sulphur contents compared to others. Hence, the potential of the physiochemical properties of the green composite produced by using this modified filler will be improved as the adhesiveness of the filler with its matrix increased.

Published: November 2021

Abstract
Hexavalent chromium is a highly toxic environmental inorganic pollutant. To eliminate toxic Cr (VI) ions in natural waters, polymer inclusion membranes (PIMs) have been developed for highly selective metal ion transport applications. The investigation of the effectiveness of Cr (VI) recovery in aqueous solutions using PIMs with varying amounts of plasticizer was studied. The pseudo-first order (PFO) kinetic model was modified to describe the amount of Cr (VI) ions that have accumulated onto the PIMs at a specific time and to evaluate the performance of the PIMs. A quantitative analysis of the modified PFO a model based on their non-linear representation and using the coefficient of determination indicates that the adsorptive properties of the PIMs are best described by the modified non-linear pseudo-first-order kinetic model (R2 > 0.9748), suggesting that the sorption process is physisorption. To show the applicability of the modified model to other transport studies, modified PFO was fitted into the experimental data that studies the transport of Zn (II) ions onto PIM (R2 > 0.95).
