2Laser performance upgrade for precise ICF experiment in SG-Ⅲ laser facility显示文摘The SG-Ⅲlaser facility(SG-Ⅲ)is the largest laser driver for inertial confinement fusion(ICF)researches in China,which has 48 beamlines and can deliver 180 kJ ultraviolet laser energy in 3 ns.In order to meet the requirements of precise physics experiments,some new functionalities need to be added to SG-Ⅲand some intrinsic laser performances need upgrade.So at the end of SG-Ⅲ's engineering construction,the 2-year laser performance upgrade project started.This paper will introduce the newly added functionalities and the latest laser performance of SG-Ⅲ.With these function extensions and performance upgrade,SG-Ⅲis now fully prepared for precise ICF experiments and solidly paves the way towards fusion ignition.Wanguo Zheng Xiaofeng Wei Qihua Zhu Feng Jing Dongxia Hu Xiaodong Yuan Wanjun Dai Wei Zhou Fang Wang Dangpeng Xu Xudong Xie Bin Feng Zhitao Peng Liangfu Guo Yuanbin Chen Xiongjun Zhang Lanqin Liu Donghui Lin Zhao Dang Yong Xiang Rui Zhang Fang Wang Huaiting Jia Xuewei Deng 2017Matter and Radiation at Extremes2017,2,5:13
3The Tibetan Plateau Surface–Atmosphere Coupling System and Its Weather and Climate Effects: The Third Tibetan Plateau Atmospheric Science Experiment显示文摘The Tibetan Plateau(TP) is a key area affecting forecasts of weather and climate in China and occurrences of extreme weather and climate events over the world. The China Meteorological Administration, the National Natural Science Foundation of China, and the Chinese Academy of Sciences jointly initiated the Third Tibetan Plateau Atmospheric Science Experiment(TIPEX-Ⅲ) in 2013, with an 8–10-yr implementation plan. Since its preliminary field measurements conducted in 2013, routine automatic sounding systems have been deployed at Shiquanhe, Gaize, and Shenzha stations in western TP, where no routine sounding observations were available previously. The observational networks for soil temperature and soil moisture in the central and western TP have also been established. Meanwhile, the plateau-scale and regional-scale boundary layer observations, cloud–precipitation microphysical observations with multiple radars and aircraft campaigns, and tropospheric–stratospheric air composition observations at multiple sites, were performed. The results so far show that the turbulent heat exchange coefficient and sensible heat flux are remarkably lower than the earlier estimations at grassland, meadow, and bare soil surfaces of the central and western TP. Climatologically, cumulus clouds over the main body of the TP might develop locally instead of originating from the cumulus clouds that propagate northward from South Asia. The TIPEX-Ⅲ observations up to now also reveal diurnal variations, macro-and microphysical characteristics, and water-phase transition mechanisms, of cumulus clouds at Naqu station. Moreover, TIPEX-Ⅲ related studies have proposed a maintenance mechanism responsible for the Asian 'atmospheric water tower' and demonstrated the effects of the TP heating anomalies on African, Asian, and North American climates. Additionally, numerical modeling studies show that the Γ distribution of raindrop size is more suitable for depicting the TP raindrop characteristics compared to the M–P distribution, the overestimation of sensible heat flux can be reduced via modifying the heat transfer parameterization over the TP, and considering climatic signals in some key areas of the TP can improve the skill for rainfall forecast in the central and eastern parts of China. Furthermore, the TIPEX-Ⅲ has been promoting the technology in processing surface observations, soundings, and radar observations, improving the quality of satellite retrieved soil moisture and atmospheric water vapor content products as well as high-resolution gauge–radar–satellite merged rainfall products, and facilitating the meteorological monitoring, forecasting, and data sharing operations.Ping ZHAO Yueqing LI Xueliang GUO Xiangde XU Yimin LIU Shihao TANG Wenming XIAO Chunxiang SHI Yaoming MA Xing YU Huizhi LIU La JIA Yun CHEN Yanju LIU Jian LI Dabiao LUO Yunchang CAO Xiangdong ZHENG Junming CHEN An XIAO Fang YUAN Donghui CHEN Yang PANG Zhiqun HU Shengjun ZHANG Lixin DONG Juyang HU Shuai HAN Xiuji ZHOU 2019Journal of Meteorological Research2019,33,3:4

7Reducing the mode-mismatch noises in atom–light interactions via optimization of the temporal waveform显示文摘Atom–light interface is at the core of quantum metrology and quantum information science.Associated noises during interaction processes are always inevitable and adverse.In this paper,we perform the stimulated Raman scattering(SRS)in a hot Rb 87 vapor cell and demonstrate the reduction of related noises originated from mode mismatch via optimizing the temporal waveform of the input seed.By using the seed with the optimized mode,the intensity fluctuation of the signal field generated in atom–light interaction is decreased by 4.3 dB.Furthermore,the fluctuation of the intensity difference between the signal and atomic spin wave is reduced by 3.1 dB.Such a temporal mode-cleaning method can be applied to improve the precision of atom interferometry using SRS and should be helpful for quantum information processing based on an atom–light correlated system.Xiaotian Feng Zhifei Yu Bing Chen Shuying Chen Yuan Wu Donghui Fan Chun-Hua Yuan L.Q.Chen Z.Y.Ou Weiping Zhang 2020Photonics Research2020,8,11:1

10Enhancement of Soil Discharge Channels on Potential Surrounding Buried Cables Under Impulsive Currents显示文摘Substations have a large number of signal transmission cables beneath the ground.Both the insulation safety and signal reliability of the cables are affected severely by the electromagnetic field.Under high-amplitude impulsive currents,the dispersion of currents can cause soil discharge and thus cause unexpected distortions in an electromagnetic field.This paper focuses on the distortions of the electric field.In general,soil discharge channels occur in the vicinity of the independent rod.Closer development of the channel might enhance the electric field distribution and the potential surrounding the outer insulation of the cables(i.e.the surface potential on the cable).Therefore,this paper establishes a platform for observing the soil discharge channel and measuring the surface potential.Direction characteristic of the channel is extracted from the captured image of soil discharge channels and the surface potential is obtained by the measured coupling capacitive current on the shield experimentally.This paper also presents an improved model considering a dynamic growing discharge channel for the transient analysis of the grounding electrode.Study results show the surface potential increases as the discharge channel approaches the cable.To quantify this enhancement effect,the ratio of the highest to the lowest value of surface potential in different directions is taken as the multiple of the surface potential increase.The calculated multiples of the surface potential increase are in the range of 1 to 1.64 times under different conditions by the improved model.Therefore,taking the soil discharge channel into account is helpful to accurately analyze the impulsive interference of buried cables.Wenxia Sima Xiaochuan Li Tao Yuan Ming Yang Donghui Luo Jialun Li 2022CSEE Journal of Power and Energy Systems2022,8,6:1

12Pepper variome reveals the history and key loci associated with fruit domestication and diversification显示文摘Pepper(Capsicum spp.)is an important vegetable crop that provides a unique pungent sensation when eaten.Through construction of a pepper variome map,we examined the main groups that emerged during domestication and breeding of C.annuum,their relationships and temporal succession,and the molecular events underlying the main transitions.The results showed that the initial differentiation in fruit shape and pungency,increase in fruit weight,and transition from erect to pendent fruits,as well as the recent appearance of large,blocky,sweet fruits(bell peppers),were accompanied by strong selection/fixation of key alleles and introgressions in two large genomic regions.Furthermore,we identified Up,which encodes a BIG GRAIN protein involved in auxin transport,as a key domestication gene that controls erect vs pendent fruit orientation.The up mutation gained increased expression especially in the fruit pedicel through a 579-bp sequence deletion in its 5′upstream region,resulting in the phenotype of pendent fruit.The function of Up was confirmed by virus-induced gene silencing.Taken together,these findings constitute a cornerstone for understanding the domestication and differentiation of a key horticultural crop.Yacong Cao Kang Zhang Hailong Yu Shumin Chen Donghui Xu Hong Zhao Zhenghai Zhang Yinqing Yang Xiaozhen Gu Xinyan Liu Haiping Wang Yaxin Jing Yajie Mei Xiang Wang Véronique Lefebvre Weili Zhang Yuan Jin Dongliang An Risheng Wang Paul Bosland Xixiang Li IIan Paran Baoxi Zhang Giovanni Giuliano Lihao Wang Feng Cheng 2022Molecular Plant2022,15,11:0
13Non-fullerene acceptor fibrils enable efficient ternary organic solar cells with 16.6% efficiency显示文摘Optimizing the components and morphology within the photoactive layer of organic solar cells(OSCs)can significantly enhance their power conversion efficiency(PCE).A new A-D-A type non-fullerene acceptor IDMIC-4F is designed and synthesized in this work,and is employed as the third component to prepare high performance ternary solar cells.IDMIC-4F can form fibrils after solution casting,and the presence of this fibrillar structure in the PBDB-T-2F:BTP-4F host confines the growth of donors and acceptors into fine domains,as well as acting as transport channels to enhance electron mobility.Single junction ternary devices incorporating 10 wt%IDMIC-4F exhibit enhanced light absorption and balanced carrier mobility,and achieve a maximum PCE of 16.6%compared to 15.7%for the binary device,which is a remarkable efficiency for OSCs reported in literature.This non-fullerene acceptor fibril network strategy is a promising method to improve the photovoltaic performance of ternary OSCs.Donghui Li Xiaolong Chen Jinglong Cai Wei Li Mengxue Chen Yuchao Mao Baocai Du Joel A.Smith Rachel C.Kilbride Mary E.O'Kane Xue Zhang Yuan Zhuang Pang Wang Hui Wang Dan Liu Richard A.L.Jones David G.Lidzey Tao Wang 2020Science China Chemistry2020,63,10:0
14HIGH-TEMPERATURE TEM IN SITU STUDY OF GROWTH KINETICS OF BAINITE IN β BRASS显示文摘In situ observation of the growth process of bainitic plate in βbrass by means of high-temper-ature TEM is conducted.The lengthening and thickening kinetics of bainitic plate is analysedwith Trivedi’s model and Zener-Hillert’s model,respectively.It is found that the stackingfault substructure exists just in the growth tip of fresh bainitie plate and so does the shearstress in the matrix around the tip.The measured lengthening rate of bainitic plate is not con-sistent with Trivedi’s model.The thiekening process is only macroscopieally controlled by vol-ume diffusion but its nature is a shear process.YANG Yanqing LIU Donghui KANG Mokuang Northwestern Polytechnical University,Xi’an,ChinaSUN Yuan Beijing Centre of Physical and Chemical Analysis,Beijing,China 1992Acta Metallurgica Sinica(English Letters)1992,5,5:0
15Modulating the alloying mode in the doping-induced synthesis of Au-Pd nanowires显示文摘Heterogeneous doping is one effective strategy for synthesizing metal alloy nanowires.Herein,the heterogeneous doping processes of Pd on the ultrathin Au nanowires were systematically modulated and investigated.Au-Pd alloy nanowires with various morphologies and lattice structures can be obtained by adjusting the morphology of the precursor Au nanowires and the kinetics of the heterogeneous doping processes.The effects of the rate of Pd reduction and the concentration of the ligand oleylamine(OAm)on the Pd deposition and alloying mode were articulated.Generally,as the Pd deposition rate decreases,the Pd deposition and alloying mode switches from the island-forming Stransky–Krastanov(SK)mode to the epitaxial Frank-van der Merwe(FM)mode,and eventually to an unconventional twisting alloying mode,where the interdiffusion of Pd and Au causes drastic rearrangement of the lattice structure and formation of helical structures.The kinetics-related variation of alloying mode could also be observed in the Au-Ag nanowires,demonstrating a general design principle for the synthesis of alloy nanostructures.In addition,the electrocatalytic performance of various Au-Pd nanowires was evaluated,and the alloy nanowire formed via the SK mode was found to be an excellent electrocatalyst for oxygen reduction and ethanol oxidation.Hui Jin Xiaoliang Wei Lecheng Zhao Jialong Yu Qiao Pan Shumin Li Qian Wang Zhaotong Yuan Dan Yang Donghui Zhao Hongyu Chen Yawen Wang 2024Nano Research2024,17,4:0
