1The Lyman-alpha Solar Telescope(LST) for the ASO-S mission——Ⅱ. design of LST显示文摘As one of the three payloads for the Advanced Space-based Solar Observatory(ASO-S)mission,the Lyman-alpha(Lyα)Solar Telescope(LST)is composed of three instruments:a Solar Corona Imager(SCI),a LyαSolar Disk Imager(SDI)and a full-disk White-light Solar Telescope(WST).When working in-orbit,LST will simultaneously perform high-resolution imaging observations of all regions from the solar disk to the inner corona up to 2.5 R⊙(R⊙stands for the mean solar radius)with a spatial resolution of 4.8′′and 1.2′′for coronal and disk observations,respectively,and a temporal resolution of 30–120 s and 1–120 s for coronal and disk observations,respectively.The maximum exposure time can be up to20 s due to precise pointing and image stabilization function.Among the three telescopes of LST,SCI is a dual-waveband coronagraph simultaneously and independently observing the inner corona in the HI Lyα(121.6±10 nm)line and white light(WL)(700±40 nm)wavebands by using a narrowband Lyαbeam splitter and has a field of view(FOV)from 1.1 to 2.5 R⊙.The stray-light suppression level can attain<10^-6 B⊙(B⊙is the mean brightness of the solar disk)at 1.1 R⊙and≤5×10^-8 B⊙at 2.5 R⊙.SDI and WST are solar disk imagers working in the Lyαline and 360.0 nm wavebands,respectively,which adopt an off-axis two-mirror reflective structure with an FOV up to 1.2 R⊙,covering the inner coronal edge area and relating to coronal imaging.We present the up-to-date design for the LST payload.Bo Chen Hui Li Ke-Fei Song Quan-Feng Guo Pei-Jie Zhang Ling-Ping He Shuang Dai Xiao-Dong Wang Hai-Feng Wang Chun-Long Liu Hong-Ji Zhang Guang Zhang Yunqi Wang Shi-Jie Liu Hong-Xin Zhang Lei Liu Shi-Lei Mao Yang Liu Jia-Hao Peng Peng Wang Liang Sun Yang Liu Zhen-Wei Han Yan-Long Wang Kun Wu Guang-Xing Ding Peng Zhou Xin Zheng Ming-Yi Xia Qing-Wen Wu Jin-Jiang Xie Ya Chen Shu-Mei Song Hong Wang Bo Zhu Chang-Bo Chu Wen-Gang Yang Li Feng Yu Huang Wei-Qun Gan Ying Li Jing-Wei Li Lei Lu Jian-Chao Xue Bei-Li Ying Ming-Zhe Sun Cheng Zhu Wei-Min Bao Lei Deng Zeng-Shan Yin 2019Research in Astronomy and Astrophysics2019,19,11:6
2Room temperature preparation of highly stable cesium lead halide perovskite nanocrystals by ligand modification for white lightemitting diodes显示文摘The poor stability of halide perovskite nanocrystals(NCs)has severely hindered future practical application.Herein,we proposed a facile and effective ligand modification route to synthesize stable CsPbBr_(3) nanocrystals by introducing a double-terminal ligand,namely 4,4'-Azobis(4-cyanovalericacid)(CA),to replace the conventional oleic acid(OA)ligand at room temperature.The as-synthesized CsPbBr_(3)-CA not only possesses high photoluminescence quantum yield(72%)related to the reduced trap defects,but also shows significantly improved stability exposure to water,ethanol,light,and/or heat benefiting from the CA ligand anchored to NC surfaces tightly.The photoluminescence intensity of CsPbBr_(3)-CA maintains about 80%and 75%of its initial emission intensity after immersed in water or ethanol for 360 min,respectively,whereas that of the CsPbBr_(3)-OA was quenched completely within a few minutes.Moreover,an all-inorganic white light-emitting diode(LED)covered 126%National Television System Committee(NTSC)standard and 92%Rec.2020 standard was fabricated by combining the green CsPbBr_(3)-CA and commercial red-emitting K2SiF6:Mn4+(KSF)phosphors onto a blue LED chip.Thus,the presented work initiates the development of the room temperature preparation of high quality CsPbBr_(3) and shows prospect for next-generation displays.Yu Zhang Guishun Li Changkun She Shaohua Liu Fangyu Yue Chengbin Jing Ya Cheng Junhao Chu 2021Nano Research2021,14,8:3

4A systematic investigation of high harmonic generation using mid-infrared driving laser pulses显示文摘We report on a systematic investigation of the influences of gas pressure,focal position and focusing geometry on high harmonic generation by use of mid-infrared femtosecond laser pulses. We also discuss the spatial characteristics of harmonics under different focusing conditions. By optimizing the parameters,we experimentally observed the generation of 1 kHz,low divergence coherent X-ray beams in the water-window region.YAO JinPing 1,2 ,XIONG Hui 1 ,XU Han 1 ,FU YuXi 1,2 ,ZENG Bin 1,2 ,CHU Wei 1,2 ,CHENG Ya 1 ,XU ZhiZhan 1 ,LIU XiaoJun 3 & CHEN Jing 4,5 1 State Key Laboratory of High Field Laser Physics,Shanghai Institute of Optics and Fine Mechanics,Chinese Academy of Sciences,Shanghai 201800,China 2 Graduate University of Chinese Academy of Sciences,Beijing 100049,China 3 State Key Laboratory of Magnetic Resonance and Atomic and Molecular Physics,Wuhan Institute of Physics and Mathematics,Chinese Academy of Sciences,Wuhan 430071,China 4 Institute of Applied Physics and Computational Mathematics,Beijing 100088,China 5 Center for Applied Physics and Technology,Peking University,Beijing 100084,China 2010Science China(Physics,Mechanics & Astronomy)2010,53,6:3
5Suppression of bend loss in writing of three-dimensional optical waveguides with femtosecond laser pulses显示文摘Optical waveguides are one of the fundamental building blocks for integrated photonic applications[1-6].Recently,femtosecond laser has been used for inscribing optical waveguides in various transparent materials such as glass,crystals and polymers thanks to the unique capability of the locally modifying refractive index in the vicinity of the focal spot[7-11].This has allowed producing three-dimensional photonic circuits for a broad spectrum of applications ranging from quantum information processing andZhengMing Liu Yang Liao Zhi Wei Fang Wei Chu Ya Cheng 2018Science China(Physics,Mechanics & Astronomy)2018,61,7:3

17The Expression of Estrogen Receptor Subtypes in Prolactinomas and Their Relationship to Tumor Biological Behavior显示文摘Dopamine agonists(DA) are a first-line therapy for prolactinomas(PA). However, nearly 10% of prolactinomas do not respond to DA therapy. A considerable number of studies have shown that estrogen plays an important role in the development of prolactinomas. However, the expression of estrogen receptors(ER) in prolactinomas has not been fully explored. Accordingly, we examined the levels of ESR1 and its subtypes Δ5-Del-ESR1 and ESR2 m RNA in prolactinomas. In the present study, we found that ESR1 m RNA levels were significantly lower in women of childbearing age group compared to men(P<0.01) and post-menopausal women(P<0.05). In addition, ESR1 m RNA levels showed a significant positive correlation with the levels of prolactin(PRL). Moreover, ESR1 m RNA levels were significantly lower in noninvasive prolactinomas compared to invasive prolactinomas.LI Chu Zhong GUI Song Bai ZONG Xu Yi ZHANG Ya Zhuo 2015Biomedical and Environmental Sciences2015,28,11:1
18Beam charge integration in external beam PIXE–PIGE analysis utilizing proton backscattering with an extraction window显示文摘In this study,we present a new method for the indirect integration of beam charges in external beam proton-induced X-ray emission and proton-induced c-ray emission(PIXE–PIGE) analysis.We recorded proton spectra backscattered by a Kapton film extraction window in different sample situations and under different beam currents.We also simulated backscattering spectra using the simulation of backscattering spectra program(SIMNRA).We determined that in a specific geometrical arrangement,different sample situations did not significantly affect factor C_Q(the ratio between integral backscattering proton counts and integral beam charges).We also studied the reproducibility and beam current dependence of factor C_Q.The statistic factor of C_Q was28.95 ± 0.6 kilo counts/l C,with a relative standard deviation of 2.0 %.Significantly,in external beam PIXE–PIGE analysis,we were able to calculate beam charge integration from the integral backscattering proton counts in an energy region.Ya Xu Mi Xu Guang-Fu Wang Chen-Long Zheng Meng-Lin Qiu Ying-Jie Chu 2016Nuclear Science and Techniques2016,27,6:1
