| 1 | Hundred-Joule-level,nanosecond-pulse Nd:glass laser system with high spatiotemporal beam quality显示文摘A 100-J-level Nd:glass laser system in nanosecond-scale pulse width has been constructed to perform as a standard source of high-fluence-laser science experiments. The laser system, operating with typical pulse durations of 3–5 ns and beam diameter 60 mm, employs a sequence of successive rod amplifiers to achieve 100-J-level energy at 1053 nm at3 ns. The frequency conversion can provide energy of 50-J level at 351 nm. In addition to the high stability of the energy output, the most valuable of the laser system is the high spatiotemporal beam quality of the output, which contains the uniform square pulse waveform, the uniform flat-top spatial fluence distribution and the uniform flat-top wavefront. | Sensen Li Yulei Wang Zhiwei Lu Lei Ding Yi Chen Pengyuan Du Dexin Ba Zhenxing Zheng Xin Wang Hang Yuan Chengyu Zhu Weiming He Dianyang Lin Yongkang Dong Dengwang Zhou Zhenxu Bai Zhaohong Liu Can Cui | 2016 | High Power Laser Science and Engineering2016，4，1： | 3 |
| 2 | The influence of YS-I on the Dll4-Notchl signaling pathway显示文摘在这研究,我们在表明小径的 Dll4-Notch1 调查了角色和 p43 和 YS-1 (recombinant 人 p43 蛋白质) 的分子的机制。p43 蛋白质指向的活跃、小介入的 RNA 和 recombinant plasmid 被用来感染人的脐的静脉 endothelial 房间(HUVEC ) 。三维的发芽模型, endothelial 房间移植试金,并且发芽并且试管形成试金被用来在 angiogenesis 推出 p43 和 YS-1 的函数。半量的反向的抄写聚合酶链反应和西方的污点分析被执行在在 HUVEC 发信号的 Dll4-Notch1 检测 p43 的效率。它被发现 p43 的那 silencing 和 overexpression 能 upregulate Dll4 槽口并且刺激 angiogenesis。p43 在 angiogenesis 起一个复杂作用。当集中在 100 nM 下面时,它支持 angiogenesis;相反,当集中是超过 100 nM 时,它禁止 angiogenesis。在这研究,我们发现 p43 的表示水平在 60 nM 下面。然而, recombinant 人 p43 蛋白质, YS-1,发芽的禁止的 endothelial 房间,和 YS-1 的 500 g/ml 稀释了 Dll4-Notch1 发信号的激活。这些结果建议 YS-1 能直接通过 Dll4-Notch1 信号 transduction 小径禁止 angiogenesis,当 p43 在这条发信号的小径起一个 modulating 作用时。 | Li Sun Qingqing Yang Ping Wang Datao Liu Wenlu Liang Sensen Lin Shengtao Yuan | 2014 | Acta Biochimica et Biophysica Sinica2014，46，1： | 1 |

| 4 | Rice OsUBR7 modulates plant height by regulating histone H2B monoubiquitination and cell proliferation显示文摘Plant height is an important agronomic trait for lodging resistance and yield.Here,we report a new plantheight-related gene,OsUBR7 in rice(Oryza sativa L.);knockout of OsUBR7 caused fewer cells in internodes,resulting in a semi-dwarf phenotype.OsUBR7 encodes a putative E3 ligase containing a plant homeodomain finger and a ubiquitin protein ligase E3 component N-recognin 7(UBR7)domain.OsUBR7 interacts with histones and monoubiquitinates H2B(H2Bub1)at lysine148 in coordination with the E2 conjugase OsUBC18.OsUBR7 mediates H2Bub1 at a number of chromatin loci for the normal expression of target genes,including cell-cycle-related and pleiotropic genes,consistent with the observation that cell-cycle progression was suppressed in the osubr7 mutant owing to reductions in H2Bub1 and expression levels at these loci.The genetic divergence of OsUBR7 alleles among japonica and indica cultivars affects their transcriptional activity,and these alleles may have undergone selection during rice domestication.Overall,our results reveal a novel mechanism that mediates H2Bub1 in plants,and UBR7 orthologs could be utilized as an untapped epigenetic resource for crop improvement. | Yangyi Zheng Sensen Zhang Yanqiu Luo Fuquan Li Jiantao Tan Bin Wang Zhe Zhao Huifang Lin Tingting Zhang Jianhong Liu Xupeng Liu Jingxin Guo Xianrong Xie Letian Chen Yao-Guang Liu Zhizhan Chu | 2022 | Plant Communications2022，3，6： | 0 |
| 5 | Fundamental understanding of high-capacity lithium-excess cathodes with disordered rock salt structure显示文摘As a new class of lithium rich cathodes,disordered rock-salt cathodes have been of primary interest,because of their ability to deliver a promisingly high capacity up to 300 mAh/g.Nevertheless,some fundamental issues are yet to be fully understood and a comprehensive mastering of their solid-state chemistry,kinetics and thermal stability is required.Here,we select a high capacity cation-disordered positive electrode-Li_(1.2)Ni_(0.4)Nb_(0.4)O_(2)as a model compound to study intrinsic reaction mechanism,including charge compensation mechanism,kinetics,thermal stability,and structural evolution.By combining soft and hard X-ray absorption spectroscopy(XAS),X-ray photoelectron spectroscopy(XPS)with operando and exsitu differential scanning calorimetry(DSC),galvanostatic intermittent titration technique(GITT),cyclic voltammetry(CV),and X-ray diffraction(XRD),we present holistic information on disordered rock-salt cathode.This work provides beneficial insights into designing and tailoring new positive electrodes with disordered rock-salt structure. | Hao Lin Beatriz Moreno Kamil Kucuk Sensen Zhang Shankar Aryal Zheng Li Carlo U.Segre Jassiel Rodriguez Dhanya Puthusseri Lirong Cai Xuechen Jiao Vilas G.Pol | 2021 | Journal of Materials Science & Technology2021，，15： | 0 |
| 6 | Double-Doped Carbon-Based Electrodes with Nitrogen and Oxygen to Boost the Areal Capacity of Zinc-Bromine Flow Batteries显示文摘Ensuring a stable power output from renewable energy sources,such as wind and solar energy,depends on the development of large-scale and long-duration energy storage devices.Zinc–bromine fl ow batteries(ZBFBs)have emerged as cost-eff ective and high-energy-density solutions,replacing expensive all-vanadium fl ow batteries.However,uneven Zn deposition during charging results in the formation of problematic Zn dendrites,leading to mass transport polarization and self-discharge.Stable Zn plating and stripping are essential for the successful operation of high-areal-capacity ZBFBs.In this study,we successfully synthesized nitrogen and oxygen co-doped functional carbon felt(NOCF4)electrode through the oxidative polymerization of dopamine,followed by calcination under ambient conditions.The NOCF4 electrode eff ectively facilitates effi cient“shuttle deposition”of Zn during charging,signifi cantly enhancing the areal capacity of the electrode.Remarkably,ZBFBs utilizing NOCF4 as the anode material exhibited stable cycling performance for 40 cycles(approximately 240 h)at an areal capacity of 60 mA h/cm^(2).Even at a high areal capacity of 130 mA h/cm^(2),an impressive energy effi ciency of 76.98%was achieved.These fi ndings provide a promising pathway for the development of high-areal-capacity ZBFBs for advanced energy storage systems. | Xiaoyun Sun Deren Wang Haochen Hu Xin Wei Lin Meng Zhongshan Ren Sensen Li | 2024 | Transactions of Tianjin University2024，30，1： | 0 |
