| 1 | Mechanical Properties of C_f/Mg Composites Fabricated by Pressure Infiltration Method显示文摘The carbon fibers and the woven reinforced magnesium matrix composites were fabricated by pressure infiltration method.Effects of fiber species,fiber arrangement,hybrid particles and environment temperature on microstructures and properties of the composite were studied.Results showed that the mechanical properties at ambient temperature were affected by interfacial reaction.The magnesium matrix composites reinforced with graphite fibers showed higher strength and elastic modulus due to less interfacial reaction.During loading,the fibers were pulled out and the load was transferred through the interfaces,then the fiber bundles were fractured,finally the whole specimen failed.The introduction of hybrid SiC particles during fabrication can improve the mechanical properties of the magnesium matrix composites.Moreover,taking orthogonal carbon fiber woven as reinforcement can modify the anisotropy and reliability of materials. | Meihui Songt Gaohui Wu Wenshu Yang Wei Jia Ziyang Xiu Guoqin Chen | 2010 | Journal of Materials Science & Technology2010，26，10： | 6 |
| 2 | High-throughput droplet microfluidic synthesis of hierarchical metal-organic framework nanosheet microcapsules显示文摘Using two-dimensional(2D)metal-organic framework(MOF)nanosheets as new building blocks to create more complex architectures at the mesoscopic/macroscopic scale has attracted extensive interest in recent years.Nevertheless,it remains a great challenge to assemble MOF nanosheets into hierarchical hollow structures so far.In this paper,we describe a successful example of hierarchical MOF nanosheet microcapsules,with precisely controlled sizes,produced on large scale within minutes with a continuous droplet microfluidic strategy.Following a reaction/diffusion growth mechanism,the microcapsule shells feature a continuous smooth inner layer and a porous outer layer.Such hierarchical structure enables the encapsulation of magnetite nanoparticles inside and loading of dense gold nanoparticles outside the microcapsules,which exhibit highly efficient heterogeneous catalytic activity and easy recyclability.The present microfluidic assembly method offers a new pathway for preparing hierarchical MOF nanosheet structures,with the potential for extension to the formation of other 2D nanosheets in general. | Songting Wu Zhong Xin Shicheng Zhao Shengtong Sun | 2019 | Nano Research2019，12，11： | 6 |

| 4 | Molecular design of organic dyes based on vinylene hexylthiophene bridge for dye-sensitized solar cells显示文摘Three donor-(π-spacer)-acceptor(D-π-A) organic dyes,containing different groups(triphenylamine,di(p-tolyl)phenylamine,and 9-octylcarbazole moieties) as electron donors,were designed and synthesized.Nanocrystalline TiO2 dye-sensitized solar cells were fabricated by using these dyes.It was found that the variation of electron donors in the D-π-A dyes played an important role in modifying and tuning photophysical properties of organic dyes.Under standard global AM 1.5 solar condition,the DSSC based on the dye D2 showed the best photovoltaic performance:a short-circuit photocurrent density(Jsc) of 13.93 mA/cm2,an open-circuit photovoltage(Voc) of 0.71 V,and a fill factor(FF) of 0.679,corresponding to solar-to-electric power conversion efficiency(η) of 6.72%. | LIU DaXi ZHAO Bin SHEN Ping HUANG Hui LIU LiMing TAN SongTing | 2009 | Science China Chemistry2009，52，8： | 2 |
| 5 | Worst-case tolerance analysis on array antenna based on chaos-genetic algorithm显示文摘This paper studies the effect of amplitude-phase errors on the antenna performance. Via builting on a worst-case error tolerance model, a simple and practical worst error tolerance analysis based on the chaos-genetic algorithm (CGA) is proposed. The proposed method utilizes chaos to optimize initial population for the genetic algorithm (GA) and introduces chaotic disturbance into the genetic mutation, thereby improving the ability of the GA to search for the global optimum. Numerical simulations demonstrate that the accuracy and stability of the worst-case analysis of the proposed approach are superior to the GA. And the proposed algorithm can be used easily for the error tolerant design of antenna arrays. | Hao Yuan Dan Songt Qiangfeng Zhou Huaping Xu | 2012 | Journal of Systems Engineering and Electronics2012，23，6： | 2 |

| 9 | Inverted polymer solar cells with TiO_2 electron extraction layers prepared by magnetron sputtering显示文摘TiO2 thin films deposited by magnetron sputtering possess excellent optical transmittance,high refractive index,good adhesion and chemical stability.In this manuscript,TiO2 thin films deposited by magnetron sputtering was used for the first time as an electron extraction layer in inverted polymer solar cells(IPSCs),and the effect of the TiO2 thickness on the photovoltaic performance of P3HT:PC61BM IPSCs was investigated.The highest PCE value of 3.75%was obtained when the thickness of TiO2thin films was in the range between 42 nm and 73 nm.The absorption properties,morphology and structure of the TiO2 films were characterized by UV-Vis spectroscopy,SEM and Raman spectroscopy,and were related to the device performance of P3HT:PC61BM IPSCs.The results indicate that TiO2 films deposited by magnetron sputtering are an excellent electron extraction layer for IPSCs. | JIANG ZhiLiang YANG Dong WANG Nan ZHANG FuJun ZHAO Bin TAN SongTing ZHANG Jian | 2013 | Science China Chemistry2013，56，11： | 1 |
| 10 | Non-conjugated polymers as thickness-insensitive electron transport materials in high-performance inverted organic solar cells显示文摘Two non-conjugated polymers PEIE-DBO and PEIE-DCO, prepared by quaternization of polyethyleneimine ethoxylate by 1,8-dibromooctane and 1,8-dichlorooctane respectively, are developed as electron transport layer(ETL) in high-performance inverted organic solar cells(OSCs), and the effects of halide ions on polymeric photoelectric performance are fully investigated. PEIE-DBO possesses higher electron mobility(3.68×10-4 cm2 V-1s-1), higher conductivity and more efficient exciton dissociation and electron extraction, attributed to its lower work function(3.94 eV) than that of PEIE-DCO, which results in better photovoltaic performance in OSCs. The inverted OSCs with PTB7-Th: PC71BM as photoactive layer and PEIE-DBO as ETL exhibit higher PCE of 10.52%, 9.45% and 9.09% at the thickness of 9, 35 and 50 nm,respectively. To our knowledge, PEIE-DBO possesses the best thickness-insensitive performance in polymeric ETLs of inverted fullerene-based OSCs. Furthermore, PEIE-DBO was used to fabricate the inverted non-fullerene OSCs(PM6:Y6) and obtained a high PCE of 15.74%, which indicates that PEIE-DBO is effective both in fullerene-based OSCs and fullerene-free OSCs. | Zhiquan Zhang Zheling Zhang Yufu Yu Bin Zhao Sheng Li Jian Zhang Songting Tan | 2020 | Journal of Energy Chemistry2020，29，8： | 1 |

| 12 | Restructured single parabolic band model for quick analysis in thermoelectricity显示文摘The single parabolic band(SPB)model has been widely used to preliminarily elucidate inherent transport behaviors of thermoelectric(TE)materials,such as their band structure and electronic thermal conductivity,etc.However,in the SPB calculation,it is necessary to determine some intermediate variables,such as Fermi level or the complex Fermi-Dirac integrals.In this work,we establish a direct carrier-concentration-dependent restructured SPB model,which eliminates Fermi-Dirac integrals and Fermi level calculation and emerges stronger visibility and usability in experiments.We have verified the reliability of such restructured model with 490 groups of experimental data from state-of-the-art TE materials and the relative error is less than 2%.Moreover,carrier effective mass,intrinsic carrier mobility and optimal carrier concentration of these materials are systematically investigated.We believe that our work can provide more convenience and accuracy for thermoelectric data analysis as well as instructive understanding on future optimization design. | Jianbo Zhu Xuemei Zhang Muchun Guo Jingyu Li Jinsuo Hu Songting Cai Wei Cai Yongsheng Zhang Jiehe Sui | 2021 | npj Computational Materials2021，，1： | 1 |

| 16 | On the first eigenvalue of Finsler manifolds with nonnegative weighted Ricci curvature显示文摘We prove that for a compact Finsler manifold M with nonnegative weighted Ricci curvature,if its first closed(resp.Neumann)eigenvalue of Finsler-Laplacian attains the sharp lower bound,then M is isometric to a circle(resp.a segment).Moreover,a lower bound of the first eigenvalue of Finsler-Laplacian with Dirichlet boundary condition is also estimated.These generalize the corresponding results in recent literature. | YIN SongTing HE Qun SHEN YiBing | 2014 | Science China Mathematics2014，57，5： | 1 |

| 20 | Effects of spin-coating speed on the morphology and photovoltaic performance of the diketopyrrolopyrrole-based terpolymer显示文摘Polymer solar cells(PSCs) were fabricated by combining a diketopyrrolopyrrole-based terpolymer(PTBT-HTID-DPP) as the electron donor, and [6,6]-phenyl C_(61) butyric acid methyl ester(PC_(61)BM) as the electron acceptor, and the power conversion efficiency(PCE) of 4.31% has been achieved under AM 1.5 G(100 m W cm^(-2)) illumination condition via optimizing the polymer/PC_(61)BM ratio, the variety of solvent and the spin-coating speed. The impact of the spin-coating speed on the photovoltaic performance of the PSCs has been investigated by revealing the effects of the spin-coating speed on the morphology and the absorption spectra of the polymer/PC_(61)BM blend films. When the thickness of the blend films are adjusted by spin-coating a fixed concentration with different spin-coating speeds, the blend film prepared at a lower spin-coating speed shows a stronger absorption per unit thickness, and the correspond device shows higher IPCE value in the longer-wavelength region. Under the conditions of similar thickness, the blend film prepared at a lower spin-coating speed forms a more uniform microphase separation and smaller domain size which leads to a higher absorption intensity per unit thickness of the blend film in long wavenumber band, a larger short-circuit current density(J_(sc)) and a higher power conversion efficiency(PCE) of the PSC device. Noteworthily, it was found that spin-coating speed is not only a way to control the thickness of active layer but also an influencing factor on morphology and photovoltaic performance for the diketopyrrolopyrrole-based terpolymer. | Fen Wu Rongyan Hou Liang Yang Bin Zhao Songting Tan | 2016 | Science China Chemistry2016，59，4： | 1 |
