| 1 | γ-MnO2 nanorods/graphene composite as efficient cathode for advanced rechargeable aqueous zinc-ion battery显示文摘Aqueous Zn//MnO2 batteries are emerging as promising large-scale energy storage devices owing to their cost-effectiveness,high safety,high output voltage,and energy density.However,the MnO2 cathode suffers from intrinsically poor rate performance and rapid capacity deterioration.Here,we remove the roadblock by compositing MnO2 nanorods with highly conductive graphene,which remarkably enhances the electrochemical properties of the MnO2 cathode.Benefiting from the boosted electric conductivity and ion diffusion rate as well as the structural protection of graphene,the Zn//MnO2-graphene battery presents an admirable capacity of 301 mAh g^-1 at 0.5 A g^-1,corresponding to a high energy density of 411.6 Wh kg^-1.Even at a high current density of 10 A g^-1,a decent capacity of 95.8 mAh g^-1 is still obtained,manifesting its excellent rate property.Furthermore,an impressive power density of 15 kW kg^-1 is achieved by the Zn//MnO2-graphene battery. | Chao Wang Yinxiang Zeng Xiang Xiao Shijia Wu Guobin Zhong Kaiqi Xu Zengfu Wei Wei Su Xihong Lu | 2020 | Journal of Energy Chemistry2020，29，4： | 13 |
| 2 | Fractal features of soil profiles under different land use patterns on the Loess Plateau, China显示文摘Fractal theory is becoming an increasingly useful tool to describe soil structure dynamics for a better understanding of the performance of soil systems. Changes in land use patterns significantly affect soil physical, chemical and biological properties. However, limited information is available on the fractal characteristics of deep soil layers under different land use patterns. In this study, the fractal dimensions of particle size distribution(PSD) and micro-aggregates in the 0–500 cm soil profile and soil anti-erodibility in the 0–10 cm soil profile for 10 typical land use patterns were investigated in the Zhifanggou Watershed on the Loess Plateau, China. The 10 typical land use patterns were: slope cropland, two terraced croplands, check-dam cropland, woodland, two shrublands, orchard, artificial and natural grasslands. The results showed that the fractal dimensions of PSD and micro-aggregates were all significantly influenced by soil depths, land use patterns and their interaction. The plantations of shrubland, woodland and natural grassland increased the amount of larger micro-aggregates, and decreased the fractal dimensions of micro-aggregates in the 0–40 cm soil profile. And they also improved the aggregate state and aggregate degree and decreased dispersion rate in the 0–10 cm soil profile. The results indicated that fractal theory can be used to characterize soil structure under different land use patterns and fractal dimensions of micro-aggregates were more effective in this regard. The natural grassland may be the best choice for improving soil structure in the study area. | Lie XIAO Sha XUE GuoBin LIU Chao ZHANG | 2014 | Journal of Arid Land2014，6，5： | 9 |
| 3 | Comparison of attitude determination approaches using multiple Global Positioning System (GPS) antennas显示文摘GPS-based attitude system is an important research field, since it is a valuable technique for the attitude determination of platforms. There exist two classes approaches for attitude determination using the GPS. The one determines attitude via baseline estimates in two frames, the other one solves for attitude by incorporating the attitude parameters directly into the GPS measurements. However, comparisons between these two classes approaches have been unexplored. First of all, two algorithms are introduced in detail which on behalf of these two kinds of approaches. Then we present numerical simulations demonstrating the performance of our algorithms and provide a comparison evaluating. | Wang Bing Sui Lifen Xiao Guorui Duan Yu Qi Guobin | 2013 | Geodesy and Geodynamics2013，4，1： | 2 |
| 4 | Numerical Study on Heat Transfer and Flow Characteristics for Laminar Flow in a Circular Tube with Swirl Generators显示文摘This study investigated the heat transfer and flow characteristics of one kind of swirlgenerator in a circular heat exchanger tube through a numericalsimulation. The swirlflow induced by this type of swirlgenerator can obtain a high heat transfer rate with minimalpressure drop penalty. The simulations were carried out to understand the physicalbehavior of this kind of mesoscale heat enhancement component. By visualizing the heat transfer and flow characteristics, it is found that the swirlflow is induced by swirlgenerator in the circular tube couples with the impinging jet effect. After passing through the swirlgenerator, the localfriction factor of liquid can quickly return to lower levelmore quickly, while the localNusselt number maintains higher values for a distance; thus, the evaluation criterion of localperformance is improved. Single-factor optimization is used for three geometric parameters, i.e., the angle of swirlgenerator(25o, 45o, and 60o), the length of swirlgenerator(0.005, 0.01, and 0.02 m), and the center rod radius(1, 2, and 3 mm). The optimum parameters of the swirlgenerator for laminar flow of air in a circular tube are obtained, which should be 60o, 0.005 m, and 3 mm, respectively. | Yongli Sun Guobin Wen Xiaoming Xiao Bohua Ren Na Yang Luhong Zhang | 2018 | Transactions of Tianjin University2018，24，3： | 1 |

| 8 | Facile cyclic ammonium salt with the smallest size for high performance electric double layer capacitors显示文摘The smallest cyclic ammonium salt reported to date, N,N-dimethylpyrrolidinium tetrafluoroborate (P11-BF4), was successively synthesized using a synthesis route without metal ions and halogen ions, then investigated as the electrolyte with Propylene carbonate in EDLCs. The electrochemical characteristics of EDLCs assembled by 1 mol/L P11-BF4/PC paired with activated carbon electrodes were compared to traditional electrolytes. P11-BF4 has proven to have superior voltage resistance by using cyclic voltammetry and constant current charge-discharge testing. Moreover, P11-BF4 exhibits a more brilliant rate performance due to its high conductivity. These results demonstrate that P11-BF4 is an ideal electrolyte to improve the energy density and power density of supercapacitors. | Chao Wang Jing Wang Xiang Xiao Guobin Zhong Shijia Wu Kaiqi Xu Wei Zhao Wei Su Jie Zeng Baojun Wu Weili Zhang Changcheng Wu Zhiqiang Shi | 2019 | Chinese Chemical Letters2019，30，6： | 0 |
| 9 | Plug Seedling Production of Short Vine Type Sweet Potato Variety‘Ganshu No.2’显示文摘This study was conducted to investigate the effects of different vine cuttings and provide a fast method for production of high-quality sweet potato seedlings.With short vine type‘Ganshu No.2'as an experiment material,biological characteristics of sweet potato seedlings were investigated by setting three vine sections( the ingle-node section,dual-node section and three-node top bud section) using three kinds of substrates( red soil,leaf mould and pond sludge).The results showed that the dual-node vine section plus leaf mould treatment sprouted earliest( 3 d) with the highest survival rate( 86.6%),root number( 9.2 roots) and the longest root length( 5.9 cm),compared with other treatments.Therefore,dual-node vine section plus leaf mould plug seedling raising has the characteristics of short sprouting time,high survival rate and low cost.The method could provide seedlings in a short period( 20 d),improves sweet potato propagation coefficient and is worth extending and applying. | Xiaosan LIU Guobin XIAO Yazhen LI Fuliang XIAO Han LI Xiaojun XIAO Tianbao HUANG | 2018 | Agricultural Biotechnology2018，7，6： | 0 |
