Authors: Du Shasha , Shi Huahua , Zhao Yan 
Published: October 2019

Abstract
After ingestion, ethanol is mainly metabolized in the liver, eventually producing ATP and end products such as carbon dioxide and water. Because it is both water- and fat-soluble, it is easy to pass through the blood-brain barrier and affect the function of the nervous system. Overconsumption of alcohol or alcohol abuse is associated with various diseases including neurocognitive disorders. This article reviews the neurotoxicity of ethanol and discusses its possible molecular mechanisms.
The role of friction in cylindrical projectile impact on fabric structure
Authors: Guo Dafeng 
Published: October 2019

Abstract
A three-dimensional finite element analysis model for plain weave fabric was created. Impact of a rigid cylindrical projectile on a square fabric clamped along its four edges were simulated using commercially available software LS-DYNA. To reveal the role of friction in ballistic impact, comparative study was conducted in which projectile velocity, boundary condition, and material property are kept the same but friction between projectile and fabric and between yarns themselves are varied systematically. Results from the study show that the friction between projectile and fabric has little effect on fabric energy absorption but the friction between yarns themselves has apparent effect. Fabric has larger impact energy absorption capacity when friction coefficient between yarns are smaller. Smaller friction between yarns delays initiation of yarn failure, increases the duration of interaction between projectile and fabric and thus increases impact energy absorption capacity of fabric structure.

Abstract
Rutting of asphalt pavement is one of major patters premature damage modes experienced during the service period of pavement. Aggregate characteristics, especially aggregate gradation can affect the rutting performance of asphalt pavement. In order to investigate the influence of spatial structure on rutting performance, the volumetric indices such as VV, VMA and VCA were employed to characterize the spatial structure of asphalt mixture, and five different gradations of asphalt mixtures with three types of aggregate skeleton structure were prepared to conduct rutting measurement by wheel tracking test. It is demonstrated that aggregate particle size of 4.75-9.5mm can affect forming aggregate skeleton structure and rutting performance. Rutting depth at a certain period of time are concerned with VV and types of aggregate skeleton structure, and the VCAratio equal to one can be used as critical value to evaluate the types of aggregate skeleton structure. It is also indicated that fine aggregate can decrease the value of VMA and excellent stability in high-temperature of asphalt mixture should match suitable VMA. This study provides a significant reference for asphalt design and choice of aggregate gradation.
Influence of parasitic phases on the magnetic properties of BiFeO3 powders
Authors: Zhao Sen , Wang Guping , Zheng Rui , Liu Yanping 
Published: October 2019

Abstract
Single phase BiFeO3 nanoparticles were successfully prepared by sol-gel method. The influence of annealing temperature and precursor drying process on phase purity, microstructures and magnetic properties of BiFeO3 powders were explored. The precursor was pre-dried at 70 °C for 6 hours and then heated at 100 °C for 12 hours. The single-phase BiFeO3 powders were successfully obtained by annealing the dried samples at 500°C for 1 hour. However, powder X-ray diffraction reveals the presence of parasitic phase Bi2Fe4O9 or iron oxide under other preparation conditions. With the increase of annealing temperature, the content of parasitic phase Bi2Fe4O9 increases while the grain size, particle size, morphology and distribution uniformity of BiFeO3 also change. When the precursor solution was dried directly at 100°C and then annealed at 500 °C for 1 hour, the parasitic phase of Fe1.966O2.963 appeared. The particles exhibit sphere-like morphology covered with small BiFeO3 grains. With the increase of drying time, the surface grains changed and the content of parasitic phase Fe1.966O2.963 increased. FTIR and EDS confirm the existence of BiFeO3. UV-VIS measurements show that the optical band gap of BiFeO3 nano-powders decrease with the increase of the content of these two parasitic phases. In this paper, effects of these parasitic phases on the magnetic properties of BiFeO3 have been studied in detail. Results show that the ferromagnetic behavior of the powders could be attributed to the Fe1.966O2.963 parasitic phases. The parasitic phase of Bi2Fe4O9 in the powders does not change the room temperature magnetic properties of BiFeO3. Both the single phase BiFeO3 and the Bi2Fe4O9 incorporated powders exhibit bulk antiferromagnetic behavior.

Published: October 2019

Abstract
Aging treatment of ZCuZn25Al6Fe3Mn3 was conducted by muffle furnace. We studied the variation of the microstructure and properties of ZCuZn25Al6Fe3Mn3 with the increase of aging temperature. We discovered that the microstructure consists of an equiaxed β phase + a star-like Fe phase + a finely distributed phase of the dispersed phase. No distributed phase was observed when the aging temperature was low. As the aging temperature rises, the punctate phase appears, and the number of punctate phases is the highest at 500 °C . Above 500 °C, continue to raise the temperature, point-like phase aggregation grows into granular phase. As the aging temperature rises, the hardness of the alloy rises first and then decreases, the weight loss of the alloy decreases first and then rises. At 500°C, the hardness of the alloy is the highest, reaching 263 HV, and the weight loss is the smallest, about 0.3990 g.Observing the wear morphology, the wear mechanism under dry friction conditions is known as abrasive wear and adhesive wear. The optimum aging treatment process for ZCuZn25Al6Fe3Mn3 is 500 °C × 2 h air cooling.

Interface Decoration Of N-Doped Carbon Nanotube with Fe For Enhancing Oxygen Catalytic Activity
Authors: Yang Jian , Guo Heng , Xiang Fei 
Published: October 2019

Abstract
Oxygen electrocatalytic reactions, including oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are extremely important in energy storage and conversion technology. The ORR is happened in cathode electrode in fuel cells or metal air batteries when discharging, the OER is occurred in anode electrode in water splitting or rechargeable metal air batteries when charging. Currently, the high-performance catalyst developed for ORR still relies on platinum (Pt) and its alloys. On the other hand, ruthenium (Ru) oxides were demonstrated to be high performance electrocatalysts for OER. However, their scarcity, limited stability, and aggregation limited the development of electrochemistry energy storage and conversion. Herein, we synthesize a series of transition metal nanoparticles embedded in nitrogen doped carbon nanotubes (M-CNT) and further decorating the interface of N-CNT with Fe element for enhancing oxygen catalytic activities. The results show that the type of transition metal determine the morphologies of N-CNT and the catalytic performance in ORR and OER. After further modification by introducing Fe element, the Fe-CNT based catalyst displays a superior ORR activity, even surpasses that of Pt/C, the Ni-CNT based catalyst with Fe decoration also showes a significant enhancement in OER. This work provides a feasible strategy to develop highly efficient oxygen catalysts with low-cost, earth-abundant transition metal elements via further decoration.

Published: October 2019

Abstract
Corrosion of steel bars in reinforced concrete structure will reduce the bearing capacity of the structure, which will cause damage to the structure and cause great casualties and economic losses. In this paper, the same specimen was monitored by using the ultrasonic guided wave (UGW) and acoustic emission (AE). The variation trend of the cumulative number of acoustic emission impacts and the amplitude variation trend of ultrasonic guided waves were obtained in the process of monitoring steel corrosion. By analysing the curve of cumulative number of impacts and the curve of the amplitude of ultrasonic guided wave changing with time, it can be accurately obtained that the corrosion of steel reinforcement can be divided into three stages, so that the feasibility of monitoring the corrosion process of steel reinforcement can be verified by ultrasonic guided wave and acoustic emission.

Authors: Han Liang 
Published: October 2019

Abstract
The APDL language of ANSYS software is used to write program to realize the moving load of weld heat source. The thermal-elastic-plastic finite element method for multi-layer and multi-pass welding process was used to simulate the temperature and stress fields of the V-groove Q235 steel plate butt joint with a thickness of 12 mm. It is concluded that in the welding process, the maximum temperature field does not appear at the center of the heat source, but around the heat source. The farther the free end is from the weld zone after welding, the larger the deformation is. After welding, the overall stress on the upper surface of the weld is larger than that on the middle and lower surface of the weld. Post-weld stress mainly concentrates at the bottom of the weld, i.e. the bottom of the V-shaped opening, and tends to increase from small to large in the direction of thickness.

Published: October 2019

Abstract
In this work, we report that Pt nanoparticles are self-assembled by annealing Pt thin films grown on Si (100) substrates at a high temperature. After growth of Pt thin films, annealing treatment is carried out at 700 and 850 °C respectively, under high purity nitrogen environment. It is found that Pt nanoparticles are formed at annealing temperature of 700 °C, while larger sized and high-quality crystalline Pt nanoparticles are generated at an elevated temperature of 850 °C. It is also found that Pt nanoparticles present plasmon enhanced effect on the optical properties of the polymercrystalline ZnO thin films, and Pt nanoparticles prepared by 20s sputtering time leads to about 5 fold excitation enhancement compared to that without Pt nanoparticles.

Published: October 2019

Abstract
A 600 MW subcritical boiler high temperature reheater tube of 12Cr1MoV steel leaks after running for 11×104 h. Failure Analysis of the high temperature reheater is studied by optical microscope (OM), scanning electron microscopy(SEM) and energy dispersive spectroscopy(EDS), etc. The results show that under long-term service at high temperature, the alloy elements have been depleted in the matrix. The oxidation layer of the inner wall is too thick, and the micro-structure is degraded obviously. Many creep cavities and micro-cracks appear in the fire-facing side of the elbow. The micro-cracks extending along the grain boundaries are filled with oxide. In conclusion, the degradation of the microstructure caused by long term overheat is the main reason for the failure of 12Cr1MoV reheater tube, and the creep cracking causes the leak.

Authors: Wu Hao , Wu Xueyi , Zhu Zhaohui 
Published: October 2019

Abstract
Taking the water pressure test of Hohhot Pumped Storage Power Station as the research object, the steel stress was analyzed by monitoring data of 3# spiral case. It could be found that the change of steel case stress was closely related to the change of water pressure, multi-correlation coefficients were between 0.993 and 1.000. The largest steel stress (194.65MPa) was less than steel yield strength (610MPa) when the spiral case was faced to the largest inner water pressure. When the inner water pressure was up to holding pressure (3.24MPa), stress of spiral case was 20.73MPa. Under same water pressure, the stresses of up and down socket ring were 1. 1∼1.8 times as much as others in same section. When the largest inner water pressure was transmitted to the spiral case, 3.24MPa internal water pressure was endured by spiral case and 3.36MPa pressure was shared by spiral case and unit concrete. The results show that stress change of 3# spiral case is normal and steel is worked in the elastic range.
