Published: December 2021

Abstract
As the most important and dangerous front-end production link, coal mining operations will inevitably face geological disasters such as water inrush, rock burst, collapse, and fire, posing a great threat to the life and safety of miners. Among the five major geological disasters (gas, dust, water, fire, roof) in coal mines, the threat of flooding is very serious and it is one of the main disasters in coal mines. The research and development of dual-frequency excitation technology and its application in coal mine exploration have realized the elimination of potential safety hazards, improved the work efficiency and safety factor of prospectors, and realized the automated operation of the exploration process. This article explores the electric field of the intelligent algorithm’s focused dual-frequency induced polarization method in coal mine electrical exploration, and summarizes some of the advantages of the intelligent algorithm’s focused dual-frequency induced polarization method in coal mine surveying on related materials, and then conducts related experiment, through the experiment of focusing on the dual-frequency IP method in the coal mine survey, obtained the result, in the abnormal point detection experiment, the change trend of the two curves is the same, the increase is more obvious at 1.3-1.5m, and at 1.5m When reaching the limit value, when it exceeds 1.5m, it starts to fall. It shows that when there is a water-bearing anomalous body directly in front of the tunneling section, the measurement results of the two survey lines are roughly the same. Compared with the no anomaly body, the apparent resistivity and the apparent amplitude frequency both change significantly, and reach the extreme in a certain direction. However, the actual anomalous body is located 1.0m directly in front of the tunneling section, which means that the actual position of the anomaly cannot be determined based on the apparent resistivity and the extreme point position of the apparent amplitude frequency.

Authors: Panin P V , Bogachev I A , Lukina E A 
Published: December 2021

Abstract
Chemical composition, structure, and technological properties have been investigated for metal powder compositions (MPCs) of a new six-component TiAl-based alloy with Gd microadditions: Ti-31.0Al-2.5V-2.5Nb-2.5Cr-0.4Gd, wt.% (Ti-44.5Al-2V-1Nb-2Cr-0.1Gd, at.%). Three MPCs fractions (10–63, 40–100, 80–120 μm) were produced by electrode induction melting and inert gas atomization technique and targeted for the additive synthesis of parts. It is shown that the chemical composition of the MPCs for the main elements corresponds to that of the electrode. In contrast, a 1.5-fold increase of the oxygen content in the MPCs was observed, which is being the result of natural oxidation of powder particles upon air environment due to developed specific surface. It has been determined that the phase composition of the MPCs (γ+α(α2)+β) differs from the equilibrium phase composition of the electrode (γ+α2)+β0/B2) and corresponds to a rapidly quenched metastable state, which indicates high solidification rates in the atomization process, exceeding critical cooling rates of the alloy. The technological properties, specifically the powder flowability, were found to be improved for 40–100 and 80–120 μm fractions, making them applicable for additive synthesis of parts from the studied alloy by selective electron-beam melting method

Abstract
The effect of heat treatment on the mechanical properties (hardness, plasticity, yield and tensile strength) and corrosion resistance of several cast magnesium alloys with additions of rare earth metals (Y, Nd and Gd), and their surface modification by plasma electrolytic oxidation (PEO) were investigated. It was found that the heat treatment of the alloys results information of Mg12YZn, Mg3Zn3Y2 and Mg24Y5 based LPSO-phases and causes an increase in hardness and tensile strength by 5-7 and 20-25%, respectively, but at the same time, corrosion resistance of the alloysdrops by 10-20 times. PEO of the alloys after heat treatment reduced the corrosion currents by 1-3 orders of magnitude without changing the corrosion potential.

Authors: Egorov E V , Egorov V K 
Published: December 2021

Abstract
The article is concerned with peculiarities study of the quasimonochromatic optical fluxes propagation through thin planar transparent layer of multilayer coating. There is shown that these fluxes can be transported by the layer in process of its multiple consequtive total internal reflection or by the waveguide-resonance propagation manner depending on correlation between the layer width and the radiation coherence length half of transported fluxes. Efficiency comparison of these radiation transportation mechanisms showed that the waveguide-resonance propagation approach is more adequate for results description of the optical waveguides functioning. It allowed to conclude that optical waveguides (fibers) function in frame of the waveguide-resonance paradigm and the waveguide-resonance mechanism is responsible for the light fluxes transportation on great distances.

Published: December 2021

Abstract
The micro-arc oxidation method was applied to modify the surface of 3D printed titanium implants with a complex internal structure. Two different electrolyte solutions were used for thesurface modification, for which the respective working parameters of the micro-arc oxidation process were developed. Surface coatings formed with these parameters on the 3D implants have the same chemical composition and have the same surface morphology as surface coatings on 2D substrates. The measurement of the coating thickness using the X-ray microtomography demonstrates that this method is a useful tool for the thickness control of porous surface coatings at the inside and outside of the 3D titanium implants.

Abstract
Nanostructured and nanocomposite layers NiCoCrAlY+ ZrO2-7%Y2O3, ZrO2-7% Y2O3+HfO2-9%Y2O3, HfO2-9%Y2O3 with thickness of ∽ 20 μm were formed by low pressure plasma spraying. The structure and composition of the layers have been studied using a scanning electron microscopy, X-ray microanalysis, and XRD analysis. Thermal stability of the coatings has been analyzed using synchronous thermal analysis at temperatures up to 1600 °C. The results of structure and composition analysis of ZrO2-7%Y2O3+HfO2-9%Y2O3 layer suggest the formation ofnanocomposite co-doped regions of the ZrO2-HfO2-Y2O3 solid solution. The layer has greater thermal stability at temperatures up to 1600 ° C and a smaller subgrain size (∽ 33 nm) than for the ZrO2-7% Y2O3 and HfO2-9%Y2O3 layers.

The most optimal treatment mode for improving wear resistance is irradiation with a dose of 5.1017 ion/cm2.
Redesigning the Jefferson Lab Hall A beam line for high precision parity experiments
Authors: Benesch J. , Roblin Y. 
Published: December 2021

Abstract
The Continuous Electron Beam Accelerator Facility (CEBAF)
was built with a thermionic electron source and the three original
experimental hall lines reflected this. A few years after beam
delivery began a parity violation experiment was approved and two
polarimeters were installed in the Hall A beam line. The beam raster
system was placed after the new Compton polarimeter, before one
accelerator quadrupole and four quadrupoles in the new Moller
polarimeter. It was very difficult to meet experimental requirements
on envelope functions and raster shape with this arrangement so a
sixth quadrupole was installed downstream of the Moller polarimeter
to provide an additional degree of freedome. All of the parity
experiments in Hall A have been run with this still-unsatisfactory
configuration. The MOLLER experiment is predicated on achieving a
2% error on a 32 ppb asymmetry. Beam line changes are required to
meet the systematic error budget. This paper documents the existing
beam line, an interim change which can be accomplished during a
annual maintenance down, and the final configuration for MOLLER and
subsequent experiments.

Published: December 2021

AbstractLithium battery cathodes contain lithium, cobalt, nickel, and manganese. Recycling of spent lithium batteries aims to recover these elements for re-use. Liberation of cathode materials from other metals in the battery such as aluminium, copper, and iron, is essential to obtain a good leaching efficiency in the recovery of valuable metals from end-of-life lithium batteries. This study investigates the behaviour of cathode materials and other metals in spent 18650 lithium batteries during leaching in H2SO4solution with and without NaOH pre-treatment. Dissolution of aluminium using NaOH is a selective method to separate the metal from other elements. The influence of a 2-hour NaOH pre-treatment on subsequent acid leaching of cathode materials was investigated at both room temperature and 80°C. The extraction of aluminium increased to 75% at a higher temperature. Lithium concentration in the pregnant leach solution from acid leaching also increases with NaOH pre-treatment. The pre-treatment had a negligible effect on nickel, manganese, iron, and copper extraction. However, the cobalt extraction with NaOH pre-treatment was significantly lower. The result was likely due to indirect impact of less hydrogen gas was generated from a lower Al amount. The lattice structure of the leach residue for the sample with NaOH pre-treatment was monoclinic rather than rhombohedral due to stronger delithiation.

Abstract
Methylene blue dyes are widely used in textile, batik, plastic, paper, and many other industries. The remain of methylene blue dyes in the textile waste is hazardous for health and the environment. Therefore, it takes effort to deal with it. One of the efforts is the process of adsorption using adsorbents. In this study, the adsorbent ZrSiO4/Fe2O3 was synthesized using the coprecipitation method using NaOH as precipitant. Either ZrSiO4 or Fe2O3 was synthesized from Indonesia mineral local zircon sand and jarosites, respectively. The composites of ZrSiO4/Fe2O3 were prepared in %mole variation, which is 75:25; 50:50; and 25:75. All obtained composites were then characterized using X-Ray Diffraction (XRD). The XRD analysis showed that the crystal structure formed was tetragonal for ZrSiO4 and hexagonal for Fe2O3 (also known as α-Fe2O3). Evaluation toward isotherm adsorption and kinetic adsorption showed that the adsorption of MB using ZrSiO4/Fe2O3 follows the Langmuir isotherm model and pseudo-second-order model, respectively.

Composites of Na2SO4 is promising for solid electrolyte application. In this initial study, composites of Al2O3/Na2SO4 were successfully synthesized from local kaolin through an alkaline destruction method combined with sulphatization. The composites were characterized including thermal behaviour, mineral phases, chemical composition, FT-IR spectra, and microstructures. The composites consist of a-Al2O3 and Na2SO4 phases after calcination at 1300 °C. This phenomenon is confirmed by the XRF and FT-IR result. The composite consists of Al2O3 and Na2SO4 as major components, accounting 41.98% and 47.09% of the total, respectively. Meanwhile, SiO2 is found as the impurity, accounting 2.86% of the total. The vibration modes of Al-O bonds are detected at 995.27 and 524.46 cm1, whereas the SO4 bands appear at 1111.00 and 617.22 cm1. Na2SO4 exhibits a rod-like particle that cover the alumina surface in the morphology.
