| 2 | Defect and Doping Co‑Engineered Non‑Metal Nanocarbon ORR Electrocatalyst显示文摘Exploring low-cost and earth-abundant oxygen reduction reaction(ORR)electrocatalyst is essential for fuel cells and metal–air batteries.Among them,non-metal nanocarbon with multiple advantages of low cost,abundance,high conductivity,good durability,and competitive activity has attracted intense interest in recent years.The enhanced ORR activities of the nanocarbons are normally thought to originate from heteroatom(e.g.,N,B,P,or S)doping or various induced defects.However,in practice,carbon-based materials usually contain both dopants and defects.In this regard,in terms of the co-engineering of heteroatom doping and defect inducing,we present an overview of recent advances in developing non-metal carbon-based electrocatalysts for the ORR.The characteristics,ORR performance,and the related mechanism of these functionalized nanocarbons by heteroatom doping,defect inducing,and in particular their synergistic promotion effect are emphatically analyzed and discussed.Finally,the current issues and perspectives in developing carbon-based electrocatalysts from both of heteroatom doping and defect engineering are proposed.This review will be beneficial for the rational design and manufacturing of highly efficient carbon-based materials for electrocatalysis. | Jian Zhang Jingjing Zhang Feng He Yijun Chen Jiawei Zhu Deli Wang Shichun Mu Hui Ying Yang | 2021 | Nano-Micro Letters2021，13，4： | 8 |

| 5 | Effects of fibrous fillers on friction and wear properties of polytetrafluoroethylene composites under dry or wet conditions显示文摘The friction and wear behavior and mechanism as well as the mechanical properties of polytetrafluoroethylene (PTFE) composites filled with potassium titanate whiskers (PTW) and short carbon fibers (CF) under dry, wet and alkaline conditions were investigated. Experiments indicated that owing to appropriate cooling and boundary lubricating effects, the filled PTFE composites showed much lower frictional coefficient and better wear resistance under alkaline than dry and wet sliding conditions. The wear resistance of carbon-fiber-filled PTFE was much better than that of potassium titanate-whisker-filled PTFE composites in water. Results also showed that the transfer film on counterpart rings was significantly hindered by water and alkali. Hydrophilic-filler-reinforced PTFE composites yield higher wear rate when sliding under water. | Huaiyuan Wang Xin Feng Yijun Shi Xiaohua Lu | 2007 | China Particuology2007，5，6： | 4 |
| 6 | Physicochemical and tribological properties of gemini-type halogen-free dicationic ionic liquids显示文摘A series of new halogen-free dicationic ionic liquids(ILs)with different alkyl chain lengths were prepared,and the relationship between the alkyl chain length,physicochemical and tribological properties of ILs,and their role as neat lubricant for steel–steel friction pairs,was investigated.Evaluation of stability during hydrolysis and copper strip corrosion test results show that synthetic ILs are stable and not corrosive to metal contacts,due to the halogen-free anions.The friction and wear test results indicate that ILs with long alkyl chains have excellent friction-reducing and anti-wear properties,especially at high temperatures.Based on the surface three-dimensional(3D)profiles,electrical contact resistance,scanning electron microscopy(SEM),energy dispersive X-ray spectroscopy(EDS),and the X-ray photoelectron spectrometry(XPS)analysis of the worn surfaces of steel discs,we can conclude that the efficiency of ILs is due to the formation of high quality tribofilms that consist of both tribochemical reaction and ordered absorption films. | Qiangliang YU Chaoyang ZHANG Rui DONG Yijun SHI Yurong WANG Yanyan BAI Jiaying ZHANG Meirong CAI Feng ZHOU Weimin LIU | 2021 | Friction2021，9，2： | 3 |
| 7 | Effect of loss and coupling on the resonance of metamaterial:An equivalent circuit approach显示文摘In this work we establish an equivalent circuit model to analyze the resonace of the metamaterial considering the loss of the unit cell and coupling effect between them.From this model,we find that metamaterial can be divided into three categories:weak,critical and strong couplings,depending on the values of the loss and coupling strength,where the different resonant properties are presented.The physical reason of the division is whether the loss in each unit cell can be offset by energy coupling from the adjunct unit cells.Full-wave electromagnetic simulations have also been carried out to verify the equivalent circuit analysis.Our circuit analysis provides a simple and effective way to understand the coupling of the metamaterial and gives guidance for the analysis and design of the metamaterial. | ZHANG YongGang WU JingBo LIANG LanJu ZHOU GaoChao JIN BiaoBing FENG YiJun | 2014 | Science China(Information Sciences)2014，57，12： | 3 |
| 8 | Dynamic Response of Phragmites australis and Suaeda salsa to Climate Change in the Liaohe Delta Wetland显示文摘Because of its unique geographical location and ecological function, the Liaohe Delta Wetland is important in maintaining regional ecological balance and security. Monitoring and evaluating changes in the wetland are therefore of great importance. We used medium-and high-resolution satellite data, meteorological station data, and site measurement data to analyze changes in the area and spatial distribution of Phragmites australis and Suaeda salsa in the Liaohe Delta Wetland from 1998 to 2017, as well as their growth response to the climate change. The results showed that during 1998–2017, the areas of both P. australis and S. salsa wetlands alternated through periods of decreasing,increasing, and then decreasing trends. The annual change in the area and spatial distribution range of S. salsa fluctuated more than that of P. australis. The annual variation of normalized difference vegetation index(NDVI) in P. australis wetland showed an upward trend from 1998 to 2017. The area of P. australis cover that was improved, unchanged, and decreased accounted for 81.8%, 12.3%, and 5.9%, respectively, of the total area;evaporation and wind speed were the main meteorological factors affecting the NDVI;and contribution rates of the climate change and human activities to the NDVI were 73.2% and 26.8%, respectively. The area with vegetation cover being mainly S.salsa that was improved, unchanged, and decreased accounted for 63.3%, 18.3%, and 18.4%, respectively, of the total area;and no meteorological factors significantly affected the NDVI of S. salsa in the region. The interaction between vegetation growth and meteorological factors may help to explain the increasing trend in vegetation cover.The improvement in wetland vegetation also led to carbon sequestration and an increase in sequestration capacity. | Yushu ZHANG Wenying YU Ruipeng JI Yijun ZHAO Rui FENG Qingyu JIA Jinwen WU | 2021 | Journal of Meteorological Research2021，35，1： | 3 |
| 9 | Correlation of Gluten Molecular Conformation with Dough Viscoelastic Properties during Storage显示文摘Significant correlations exist for the total sample between the dough viscoelastic properties and quality, but little information about these links is available. This study investigates the relationship between the gluten molecular conformation and the dough viscoelastic properties of the Zhengmai 379 wheat variety with different relative humidity(RH) values during storage.The results showed that protein extractability, free sulfhydryl(SH) groups, and wet gluten contents decreased to a certain degree during storage, while the glutenin quantity significantly varied. Significant negative correlation coefficients were found between the dough viscosity at 50% RH and the β-turn contents at 40% RH(-0.918) or 60% RH(-0.949)(P < 0.01), the dough viscosity at50% RH and the β-turn contents at 50% RH(-0.912)(P < 0.05), and the dough viscosity at 50% RH and the α-helix/β-sheet ratio at 40% RH(-0.875), 50% RH(-0.869), or 60% RH(-0.843)(P < 0.05). Significant correlation coefficients were further observed between the dough viscosity at 50% RH and the β-sheet contents at 60% RH(0.927)(P < 0.01) and between the dough viscosity at50% RH and the β-sheet contents at 40% RH(0.910) or 50% RH(0.908)(P < 0.05). A decrease in the free SH groups of gluten and an increase in the low-molecular weight contents suggested that gliadin was incorporated via SS crosslinking to the glutenin-like protein, which did not dissolve in ethanol. | JIA Feng ZHANG Shuaibing ZHANG Yijun WANG Jinshui | 2018 | Grain & Oil Science and Technology2018，1，1： | 2 |

| 12 | Analog study of near-field focusing and subwavelength imaging with nonlinear transmission-line metamaterial显示文摘In this paper,we report an analog study of realizing near-field focusing and near-perfect imaging at harmonic frequencies using a two-dimensional(2D)left-handed nonlinear transmission line(LH NLTL)metamaterial.Firstly,we give a detailed procedure of designing LH NLTL and right-handed(RH)transmission line media that match with each other at harmonics.Then,through microwave circuit simulations,we observe strong surface waves at the boundaries between RH and LH NLTL metamaterials,which are consistent with the theoretical analysis of an LH linear superlens.Finally,we show that the LH NLTL metamaterial can act as a flat nonlinear lens that can create,with a subwavelength resolution,an image of harmonic fields of the source which is opaque at the fundamental frequency. | WANG ZhengBin FENG YiJun ZHAO JunMing JIANG Tian | 2013 | Science China(Information Sciences)2013，56，12： | 2 |
