| 1 | Breaking 12% efficiency in flexible organic solar cells by using a composite electrode显示文摘The performance of flexible organic solar cells(OSCs)significantly relies on the quality of transparent flexible electrode.Here,we used silver nanowires(AgNWs)with various weight ratios to dope high-conductive poly(3,4-ethylenedioxythiophene):polystyrene sulfonate(PH1000)to optimize the optical and electronic properties of PH1000 film.A high-quality flexible composite electrode PET/Ag-mesh/PH1000:AgNWs-20 with smooth surface,a low sheet resistance of 6Ω/sq and a high transmittance of 86%at 550-nm wavelength was obtained by doping 20 wt%AgNWs to PH1000(PH1000:AgNWs-20).The flexible OSCs based on the PET/Ag-mesh/PH1000:AgNWs-20 electrode delivered a power conversion efficiency(PCE)of12.07%with an open circuit voltage(Voc)of 0.826 V,a short-circuit current density(Jsc)of 20.90 m A/cm2and a fill factor(FF)of69.87%,which is the highest reported PCE for the flexible indium-tin oxide(ITO)-free OSCs.This work demonstrated that the flexible composite electrodes of PET/Ag-mesh/PH1000:AgNWs are promising alternatives for the conventional PET/ITO electrode,and open a new avenue for developing high-performance flexible transparent electrode for optoelectronic devices. | Guang Zeng Jingwen Zhang Xiaobin Chen Hongwei Gu Yaowen Li Yongfang Li | 2019 | Science China Chemistry2019，62，7： | 9 |
| 2 | Evaluation system for CO_2 emission of hot asphalt mixture显示文摘The highway construction industry plays an important role in economic and development,but is also a primary source of carbon emission. Accordingly, with the global climate change, energy conservation and reduction of carbon emissions have become critical issues in the highway construction industry. However, to date, a model for the highway construction industry has not been established. Hence, to implement a low-carbon construction model for highways, this study divided asphalt pavement construction into aggregate stacking, aggregate supply, and other stages, and compiled a list of energy consumption investigation. An appropriate calculation model of CO_2 emission was then built. Based on the carbon emission calculation model, the proportion of carbon emissions in each stage was analyzed. The analytic hierarchy process was used to establish the system of asphalt pavement construction with a judgment matrix, thereby enabling calculation of the weight coefficient of each link. In addition, the stages of aggregate heating, asphalt heating, and asphalt mixture mixing were defined as key stages of asphalt pavement construction. Carbon emissions at these stages accounted for approximately 90% of the total carbon emissions. Carbon emissions at each stage and their impact on the environment were quantified and compared. The energy saving construction schemes as well as the environmental and socioeconomic benefits were then proposed. Through these schemes, significant reductions in carbon emissions and costs can be achieved. The results indicate that carbon emissions reduce by 32.30% and 35.93%, whereas costs reduce by 18.58% and 6.03%. The proposed energy-saving and emission reduction scheme can provide a theoretical basis and technical support for the development of low-carbon highway construction. | Bo Peng Chunli Cai Guangkai Yin Wenying Li Yaowen Zhan | 2015 | Journal of Traffic and Transportation Engineering(English Edition)2015，2，2： | 8 |
| 3 | Adhesion forces for water/oil droplet and bubble on coking coal surfaces with different roughness显示文摘Surface roughness plays a significant role in floatability of coal.In the present paper,coking coal surface was polished by three different sandpapers and the surface properties were characterized by contact angle and roughness measurements.The effect of surface roughness on floatability was investigated by adhesion force measurement system for measuring interaction forces between droplets/bubbles and coking coal surfaces with different roughness.The results showed that the contact angle decreased with increasing roughness yet the adhesion force between the water droplet and coal surface increased owing to the increased contact line and the appearance of line pinning.Maximum adhesion forces between water and surfaces were 111.70,125.48,and 136.42μN when the roughness was 0.23,0.98,and 2.79 μm,respectively.In contrast,under a liquid environment,the adhesion forces between air bubble/oil droplet and coal surfaces were decreased with increasing roughness because of the restriction by water.Maximum adhesion forces of increasing roughness were 97.14,42.76,and 17.86 μN measured at interfaces between air bubble and coal surfaces and 169.48,145.84,and 121.02 lN between oil droplet and surfaces,respectively.Decreasing roughness could be beneficial to the spreading of oil droplets and the adhesion of bubbles which is conducive to flotation separation. | Chunyun Zhu Guosheng Li Yaowen Xing Xiahui Gui | 2021 | International Journal of Mining Science and Technology2021，31，4： | 8 |

| 5 | Machining deformation of single-sided component based on finishing allowance optimization显示文摘Owing to reliability and high strength-to-weight ratio,large thin-walled components are widely used in the aviation and aerospace industry.Due to the complex features and sequence involved in the machining process of large thin-walled components,machining deformation of component is easy to exceed the specification.In order to address the problem,it is important to retain the appropriate finishing allowance.To find the overall machining deformation,finishing allowance-induced deformation(web finishing allowance,sidewall finishing allowance)and initial residual stress-induced deformation were considered as major factors.Meanwhile,machined surface residual stress-induced deformation,clamping stress-induced deformation,thermal deformation,gravity-induced deformation and inertial force-induced deformation were neglected in the optimization model.Six-peak Gaussian function was introduced to fit the initial residual stress.Based upon the obtained function of initial residual stress,a deformation prediction model between initial residual stress and finishing allowance was established to attain the finishing allowanceinduced deformation.In addition,linear programming optimization model based on the simplex algorithm was developed to optimize the overall machining deformation.Results have concluded that the overall machining deformation reached the minimum value when sidewall finishing allowance and web finishing allowance varied between 1 and 2 mm.Additionally,web finishing allowance-induced deformation and sidewall finishing allowance-induced deformation were1.05 mm and 0.7 mm.Furthermore,the machining deformation decreased to 0.3–0.38 mm with the application of optimized finishing allowance allocation strategy,which made 39–56%reduction of the overall machining deformation compared to that in conventional method. | Xiaoyue LI Liang LI Yinfei YANG Guolong ZHAO Ning HE Xiaocen DING Yaowen SHI Longxin FAN Hui LAN Muhammad JAMIL | 2020 | Chinese Journal of Aeronautics2020，33，9： | 6 |
| 6 | Effects of climate change and human activity on lake shrinkage in Gonghe Basin of northeastern Tibetan Plateau during the past 60 years显示文摘Changes in the status of freshwater resources are a topic of major global,regional and local concern.This is especially so in the arid and semi-arid regions of China,where shortage of water resources plays a crucial role in limiting sustainable socioeconomic development,as well as in sustaining natural ecosystems.Recent climate change,as well as the effects of localized human activity,such as the use of water for irrigation agriculture,may have significant effects on the status of the water resources in the region.Here,we report the results of a study of changes in the areas of lakes in Gonghe Basin,northeastern Tibetan Plateau of China,over the last 60 years.The data were acquired from optical satellite images and demonstrate that the total water area of lakes in Gonghe Basin decreased significantly from the 1950 s to 1980 s.The cause is ascribed mainly to human activity including exploitation of farmland,against a background of increasing population;in addition,climatic data for the region demonstrate a minor drying trend during this period as the temperature increased slightly.After the construction of several reservoirs,significant amounts of water were redistributed to promote irrigation agriculture and we conclude that this caused a significant shrinkage of the natural lakes.However,both the area of farmland and the population size remained approximately constant after 1990.We conclude that the variation of the total area of lakes during the second period was mainly controlled by climatic factors(precipitation and temperature).As the regional temperature reached a new high,the area of some of the lakes decreased sharply before finally maintaining a relatively steady state.We emphasize that anthropogenic climate change and human activity have both significantly influenced the status of water resources in the arid and semi-arid regions of China. | WU Duo CHEN Fahu LI Kai XIE Yaowen ZHANG Jiawu ZHOU Aifeng | 2016 | Journal of Arid Land2016，8，4： | 6 |

| 8 | Root imaging from ground penetrating radar data by CPSO-OMP compressed sensing显示文摘As the amount of data produced by ground penetrating radar(GPR) for roots is large, the transmission and the storage of data consumes great resources. To alleviate this problem, we propose here a root imaging algorithm using chaotic particle swarm optimal(CPSO)compressed sensing based on GPR data according to the sparsity of root space. Radar data are decomposed,observed, measured and represented in sparse manner, so roots image can be reconstructed with limited data. Firstly,radar signal measurement and sparse representation are implemented, and the solution space is established by wavelet basis and Gauss random matrix; secondly, the matching function is considered as the fitness function, and the best fitness value is found by a PSO algorithm; then, a chaotic search was used to obtain the global optimal operator; finally, the root image is reconstructed by the optimal operators. A-scan data, B-scan data, and complex data from American GSSI GPR is used, respectively, in the experimental test. For B-scan data, the computation time was reduced 60 % and PSNR was improved 5.539 dB; foractual root data imaging, the reconstruction PSNR was26.300 dB, and total computation time was only 67.210 s.The CPSO-OMP algorithm overcomes the problem of local optimum trapping and comprehensively enhances the precision during reconstruction. | Chao Li Yaowen Su Yizhuo Zhang Huimin Yang | 2017 | Journal of Forestry Research2017，28，1： | 4 |
| 9 | Dopant-free hole transporting materials with supramolecular interactions and reverse diffusion for efficient and modular p-i-n perovskite solar cells显示文摘The rational design of dopant-free organic hole-transporting layer(HTL) materials is still a challenge for realizing high-efficient and stable p-i-n planar perovskite solar cells(pero-SCs). Here, we synthesized two π-conjugated small-molecule HTL materials through tailoring the backbone and conjugated side chain to carefully control molecular conformation. The resultant BDT-TPAs Th containing a planar fused benzo[1,2-b:4,5-b′]dithiophene(BDT) core and a conjugated thiophene side chain showed the planar conformation. X-ray crystallography showed a favorable stacking model in solid states under the parallel-displaced π-πand additional S-π weak-bond supramolecular interactions, thus achieving an obviously increased hole mobility without dopants.As an HTL material in p-i-n planar pero-SCs, the marginal solubility of BDT-TPA-s Th enabled inverse diffusion into the perovskite precursor solution for assisting the subsequent perovskite film growth and passivating the uncoordinated Pb2+ ion defects. As a result, the planar p-i-n pero-SCs exhibited a champion power conversion efficiency(PCE) of 20.5% and enhanced moisture stability. Importantly, the BDT-TPA-s Th HTL material also showed weak thickness-photovoltaic dependence, and the pero-SCs with blade-coated BDT-TPA-s Th as a HTL achieved a 15.30% PCE for the 1-cm2 modularized device. This HTL material design strategy is expected to pave the way toward high-performance, dopant-free and printing large-area planar p-i-n pero-SCs. | Rongming Xue Moyao Zhang Deying Luo Weijie Chen Rui Zhu Yang(Michael)Yang Yaowen Li Yongfang Li | 2020 | Science China Chemistry2020，63，7： | 4 |

| 15 | Is 1.28 parts per million biomarker specific for neural progenitor cells?显示文摘Nuclear magnetic resonance-visible mobile lipid,at 1.28 parts per million(ppm),is thought to be due to mobile lipid droplets formed in cells and has been considered unique for neural progenitor cells.However,this idea remains controversial.The present study examined the 1.28 ppm biomarker in other stem cells and non-stem cells,and explored the relationship between 1.28 ppm biomarker and mobile lipid droplets.1H nuclear magnetic resonance spectroscopy of EC109 cells,mesenchymal stem cells(MSCs) and adipogenic cells differentiated from MSCs was performed.Results show that 1.28 ppm biomarker was observed in human MSCs,but was absent from EC109 cells.Following adipogenic differentiation induced for 2 weeks,the 1.28 ppm biomarker climbed remarkably,with mobile lipid droplet generation,suggesting that the 1.28 ppm biomarker is not specific for neural progenitor cells because it is also observed in MSCs and adipogenic-induced differentiated cells.Moreover,it is possible to monitor MSCs differentiation following cell transplantation,using 1.28 ppm biomarker changes. | Zhifeng Xu Chongyang Shen Haiqiang Zhu Yaowen Chen Linping Wu Peng Huang YeyuXiao Zhiwei Shen Li Pang Xiuqin Guo Lian Ma Renhua Wu | 2010 | Neural Regeneration Research2010，5，15： | 2 |

| 18 | Effects of Mn on Microstructures and Properties of Hot Rolled Low Carbon Bainitic Steels显示文摘Two kinds of Mn-Si-Mo low carbon steels were designed to study the effects of Mn on the microstructures and properties of hot rolled low carbon bainitic steels.To reduce the production cost,a very low Mo content of 0.13%was added in both steels.After hot rolling,the mechanical properties of samples were tested.Microstructure was observed and analyzed by optical microscope and transmission electron microscope.The results show that the strength of tested steels increases with the increase in Mn content,while the elongation decreases.When Mn content increases,the bainite microstructure increases.The results can provide a theoretical basis for composition design and industrial production of low cost low carbon bainitic steels. | 王敏 徐光 WANG Li XU Yaowen XUE Zhengliang | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，1： | 1 |
