Published: March 2021

Abstract
Vanadium pentoxide (V2O5) as the cathode material has caused great concern in metal-ion batteries due to the diverse valence states of vanadium. However, structural instability and poor electrical and ionic conductivity significantly limit its application as high-efficiency electrodes. Herein, V2O5 nanosheet is directly grown on electrospun carbon nanofibers (V2O5@CNFs) by a hydrothermal method as a cathode for sodium-ion batteries. The carbon fiber skeleton can improve not only the conductivity but also buffer the volume variations of the electrodes. As the cathode of NIBs, the as-prepared V2O5@CNFs exhibits an excellent capacity of 178 mAh g−1 at 25 mA g−1 and 60 mAh g−1 at 1000 mA g−1.

Abstract
In this paper, a beam-forming acoustic imaging technology is applied to identify the spatial position and frequency characteristics of the main noise source on the key position of a ±800kV DC converter station. The test results show that the main noise sources of the AC filter field are the reactor group and the capacitor group, the noise of the reactor group has obvious peak value at 600Hz, and the noise of the capacitor group has obvious peak value at 100Hz. The main noise of DC filter field is from the reactor. The main noise source in the converter transformer area is the cooling fan array arranged outside the transformer. The maximum noise of the water cooling system is generated by the spray water on the bottom water pan of the cooling tower.

Authors: Li Kunpeng , Feng Chao , Jin Shoujie , Yao Yongming , Zhou Ning 
Published: March 2021

Abstract
This paper investigates the effect of the ambient temperature change on the overhead catenary system (OCS). Thermal expansion/contraction of the components of the overhead catenary system (OCS) are considered. Simulation results show that the temperature stress has a much greater influence on the longitudinal positioning of the contact wire than on the horizontal and vertical positioning. When ambient temperature reduces to -60°C or rises to 60°C from design temperature of 20°C, the maximum longitudinal displacement of the positioner can reach as high as 304 mm, while the maximum horizontal and vertical displacement of the positioner is within 4 mm. The decrease of temperature leads to the increase of cable tension, and the increase of temperature leads to the decrease of cable tension. When the temperature decreases from 20°C to -60°C or rises to 60°C, the tension change rate of contact wire is less than 1%, while that of messenger wire is not more than 0.01%.

Indoor formaldehyde is widely existed which poses a threat to residents’ physical health. In order to eliminate the risk of formaldehyde pollutant, individuals usually adopt formaldehyde air purifiers. In this empirical study, we aim to investigate individuals’ adoption intention of formaldehyde air purifier from the perspective of consumption values. Grounded in the Protective Action Decision Model, our research framework underlines the mechanism through which one’s personal knowledge and risk perception affect the perceived functional and non-functional values of formaldehyde air purifiers and subsequently impact the adoption intention. A survey is conducted to validate our model. This research contributes to the literature by enriching current understanding of individuals’ protective behavioral intention in the context of indoor formaldehyde.

Authors: Chen Ling , Zhu Li , Fu Feie 
Published: March 2021

Abstract
Alumina hydrophobic film is widely used, but there are few studies on its friction performance. Traditional hydrophobic films are self-assembled with a layer of low surface energy compound on the alumina film surface. The surface is in contact with other substances during use, causing the loss of low surface energy substances and reducing the hydrophobic properties of the film. We use organics and alumina alternate coatings to form an organic-inorganic composite layer, and then tested its hydrophobicity and friction performance.

Published: March 2021

Abstract
The nitrogen and phosphorus pollution of sediments has increasingly become the main cause of eutrophication in reservoir. The temporal-spatial distribution features and pollution level of nitrogen and phosphorus of sediments were revealed in Zhangze Reservoir. The nitrogen and phosphorus content of 16 sediment samples were detected, as well as sediment oxygen demand. The temporal-spatial changing rules of nitrogen and phosphorus of sediments were analyzed. The pollution level of sediments was evaluated. The results showed that the total nitrogen content of sediments varied from 506 mg/kg to 4411 mg/kg, the total phosphorus content of sediments varied from 160 mg/kg to 961 mg/kg, and the sediment oxygen demand varied from 1295.7 mg/(m2•d) to 2957.6 mg/(m2•d). The nitrogen and phosphorus content of sediments in north and south section was larger than that in middle section. The temporal variation rule of nitrogen and phosphorus content was that it increased obviously in flood season and decreased obviously in freezing stage. The nitrogen pollution level of most of the sediments was severe pollution, with the most serious pollution near the dam and at the end of the reservoir. The phosphorus pollution level of most of the sediments was mild pollution, with moderate and severe pollution near the dam and at the end of the reservoir.
