| 1 | Facile metagrating holograms with broadband and extreme angle tolerance显示文摘The emerging meta-holograms rely on arrays of intractable meta-atoms with various geometries and sizes for customized phase profiles that can precisely modulate the phase of a wavefront at an optimal incident angle for given wavelengths.The stringent and band-limited angle tolerance remains a fundamental obstacle for their practical application,in addition to high fabrication precision demands.Utilizing a different design principle,we determined that facile metagrating holograms based on extraordinary optical diffraction can allow the molding of arbitrary wavefronts with extreme angle tolerances(near-grazing incidence)in the visible–near-infrared regime.By modulating the displacements between uniformly sized meta-atoms rather than the geometrical parameters,the metagratings produce a robust detour phase profile that is irrespective of the wavelength or incident angle.The demonstration of high-fidelity meta-holograms and in-site polarization multiplexing significantly simplifies the metasurface design and lowers the fabrication demand,thereby opening new routes for flat optics with high performances and improved practicality. | Zi-Lan Deng Junhong Deng Xin Zhuang Shuai Wang Tan Shi Guo Ping Wang Yao Wang Jian Xu Yaoyu Cao Xiaolei Wang Xing Cheng Guixin Li Xiangping Li | 2018 | Light(Science & Applications)2018，7，1： | 17 |
| 2 | Nerve transfer helps repair brachial plexus injury by increasing cerebral cortical plasticity显示文摘In the treatment of brachial plexus injury, nerves that are functionally less important are transferred onto the distal ends of damaged crucial nerves to help recover neuromuscular function in the target region. For example, intercostal nerves are transferred onto axillary nerves, and accessory nerves are transferred onto suprascapular nerves, the phrenic nerve is transferred onto the musculocutaneous nerves, and the contralateral C7 nerve is transferred onto the median or radial nerves. Nerve transfer has become a major method for reconstructing the brachial plexus after avulsion injury. Many experiments have shown that nerve transfers for treatment of brachial plexus injury can help reconstruct cerebral cortical function and increase cortical plasticity. In this review article, we summarize the recent progress in the use of diverse nerve transfer methods for the repair of brachial plexus injury, and we discuss the impact of nerve transfer on cerebral cortical plasticity after brachial plexus injury. | Guixin Sun Zuopei Wu Xinhong Wang Xiaoxiao Tan Yudong Gu | 2014 | Neural Regeneration Research2014，9，23： | 4 |
| 3 | Influence of Cr^(3+) concentration on the electrochemical behavior of the anolyte for vanadium redox flow batteries显示文摘The composition of electrolyte affects to a great extent the electrochemical performance of vanadium redox flow batteries(VRB).The effects of Cr3+ concentration in the anolyte on the electrode process of V(V)/V(IV) couple have been investigated by cyclic voltammetry(CV) and electrochemical impedance spectroscopy(EIS).It was found that Cr3+ causes no side reactions,but affects the electrochemical performance of V(V)/V(IV) redox reaction,including the reaction activity,the reversibility of electrode reaction,the diffusivity of vanadium ions,the interface film impedance,and the electrode reaction impedance.The experimental results show that Cr3+ within a certain concentration range can improve the reversibility of electrode reaction and the diffusion of vanadium ions.With the Cr3+ concentration increasing from 0 to 0.30 g L-1,the reversibility of V(V)/V(IV) reaction increases,while the diffusion resistance decreases.Correspondingly,the diffusion coefficient of vanadium ions increases from(5.48-6.77) × 10-7 to(6.82-8.44) × 10-7 cm2 s-1,an increase of ~24%.However,the diffusion resistance increases and the diffusion coefficient decreases when Cr3+ concentration is over 0.30 g L-1,while the impedances of the interface,the film as well as the charge transfer increase continuously.As a result,Cr3+ with a certain concentration improves the diffusion and mass transfer process,but the resistances of the film,the interface,and the charge transfer rise.Furthermore,Cr3+ concentration of no more than 0.10 g L-1 has few effect on the electrode reaction process,and that of no more than 0.30 g L-1 is favorable to the diffusion of vanadium ions. | HUANG Fei ZHAO Qiang LUO ChunHui WANG GuiXin YAN KangPing LUO DongMei | 2012 | Chinese Science Bulletin2012，57，32： | 4 |
| 4 | 在自从 1980s: ,伪造在人口之间的连接学习的中国的人口地理和人的地理显示文摘自从 1980 年代,这篇论文在中国考察人口地理的进步。评论结果建议与它这个领域里的看不见和排斥地位的普通感觉相反,自从 1980 年代,巨大的进步在中国在人口地理被取得了。人口地理学者用地理观点做了重要贡献到大量人口问题的理解,包括移植,都市化,人口分发,在人口之间的关系,环境和资源,变老,婚姻模式,和候鸟罪,尽管如此的贡献经常没出现在地理圆。而且,人口地理学者在使新生起了一个不可缺少的作用在中国的人口研究并且伪造它的连接到人的地理,在这个多学科的领域里占据一个重要位置。对移植和都市化研究的区域的人口地理学者贡献是特别地重要的,在这些区域研究在他们的主角思考了。论文证明作为在超过 20 年隔离以后的领域里的迟到者,在中国的人口地理学者通过了自从 1980 年代,在与社会科学家一起的社会科学和增加的相互作用追上来和与开发的增加的约会的一个过程,并且极大地得益于它;然而,为逐渐地从主要溪流人地理要离间的人口地理有一个趋势,类似于然而并非象在 1990 年代末和 2000 年代初的祖籍英国的美国人地理一模一样的现象。论文主张人口地理仅仅是在菜的半路伪造在人口研究和人的地理之间的连接,并且它需要回到地理科学寻求在人口研究和人的地理的领域之间的健康平衡,并且在一个多学科的领域里支持它的进一步的开发。 | ZHU Yu DING Jinhong WANG Guixin SHEN Jianfa LIN Liyue KE Wenqian | 2016 | Journal of Geographical Sciences2016，26，8： | 2 |
| 5 | Mass production of Li Fe PO_4/C energy materials using Fe–P waste slag显示文摘To effectively solve the agglomeration problems in the solid state reaction process,pre-adding glucose is adopted to the synthesis of Li Fe PO4/C energy materials using Fe–P waste slag. The average particle & grain size of Li FeP O4/C decreases,and the impurities in Li Fe PO4/C composites reduce to a great extent. It makes great sense to the mass industrial production. The optimum synthesis conditions determined in this work are based on the orthogonal experiments. The samples synthesized in a scale of 500 g exhibit high purity,excellent electrochemical performance,high reaction activity,good reversibility,and low polarization level.The discharge capacities are 145,134,117,and 102 m Ah/g at the current densities of 0.1 C,0.2 C,0.5 C and1 C,respectively. This work puts forward a practical suggestion for mass producing environmental benign and low cost Li FeP O4/C as cathode materials of lithium ion batteries. | Gen Li Pengcheng Wu Chunhui Luo Qian Cui Guixin Wang Kangping Yan | 2015 | Journal of Energy Chemistry2015，24，4： | 2 |

| 16 | Charge accumulation characteristic on polymer insulator surface under AC voltage in air and C_(4)F_(7)N/CO_(2)mixtures显示文摘Charge accumulation has always been a problem for the safe operation of gas insulated switchgear(GIS)/gas insulated transmission line(GIL)both under AC and DC.It is of great significance to investigate the behaviour of surface charge under high voltage.In this study,the charge distribution characteristics and accumulation mechanism on insulator surface in air and heptafluorobutyronitrile/carbon dioxide(C_(4)F_(7)N/CO_(2))mixtures under AC voltage are studied via the means of surface potential measurement and inversion algorithm,combined with the improved method of controlling the truncated phase of AC voltage.The results show that under the needle–plate electrode structure,charge distribution on the insulator surface presents a three-tier concentric circle structure both in air and C_(4)F_(7)N/CO_(2) gas mixtures,and the charge composition of the innermost circle is closely related to the truncated phase of AC voltage.Under the same amplitude of voltage,the range of charge distribution on insulator surface in C_(4)F_(7)N/CO_(2) mixtures is smaller than that in air,with the negative charges domination.It is suggested that the characteristic of charge distribution in C_(4)F_(7)N/CO_(2) mixtures is related to the larger electron attachment crosssection of C4F7N gas in a wide range of electron energy distribution. | Dayu Li Guixin Zhang Tianyu Wang Yicen Hou | 2020 | High Voltage2020，5，2： | 1 |
