1Calibration procedures for the CHASE/HIS science data显示文摘The Hα line is an important optical line in solar observations containing the information from the photosphere to the chromosphere. To study the mechanisms of solar eruptions and the plasma dynamics in the lower atmosphere, the Chinese Hα Solar Explorer(CHASE) was launched into a Sun-synchronous orbit on October 14, 2021. The scientific payload of the CHASE satellite is the Hα Imaging Spectrograph(HIS). The CHASE/HIS acquires, for the first time, seeing-free Hα spectroscopic observations with high spectral and temporal resolutions. It consists of two observational modes. The raster scanning mode provides full-Sun or region-of-interest spectra at Hα(6559.7-6565.9 ?) and Fe I(6567.8-6570.6 ?) wavebands. The continuum imaging mode obtains full-Sun photospheric images at around 6689 ?. In this paper, we present detailed calibration procedures for the CHASE/HIS science data, including the dark-field and flat-field correction, slit image curvature correction, wavelength and intensity calibration, and coordinate transformation. The higher-level data products can be directly used for scientific research.Ye Qiu ShiHao Rao Chuan Li Cheng Fang MingDe Ding Zhen Li YiWei Ni WenBo Wang Jie Hong Qi Hao Yu Dai PengFei Chen XiaoSheng Wan Zhi Xu Wei You Yuan Yuan HongJiang Tao XianSheng Li YuKun He Qiang Liu 2022Science China(Physics,Mechanics & Astronomy)2022,65,8:3
2Carbon-coated Li_4Ti_5O_(12) Anode Materials Synthesized Using H_2TiO_3 as Ti Source显示文摘Two low-cost synthesis routes have been developed to fabricate carbon-coated Li4Ti5O12 by using H2 Ti O3instead of anatase Ti O2 as Ti source through solid-state reaction process. One route is a direct solid mixture of H2 Ti O3, Li2CO3 and pitch followed by high-temperature solid-state reaction. The other includes mixture of H2 Ti O3and Li2CO3 with pitch dissolved in furanidine under vacuum and the same solid-state reaction procedure is followed after the mixture is totally dried. Microstructural investigations indicate that H2 Ti O3exhibits secondary aggregates morphology with primary particle sizes of 10e20 nm. Carbon-coating layers with thickness of 2e3 nm have been observed on Li4Ti5O12 synthesized by the two routes. Cyclic performance, rate capability and electrochemical impedance spectrum of the two Li4Ti5O12/C composites have been performed, which indicate that Li4Ti5O12/C obtained by furanidine-assisted mixture exhibits better electrochemical performance than Li4Ti5O12/C synthesized by direct solid mixture. The possible reasons have been discussed. The low-cost synthesis routes of Li4Ti5O12/C using H2 Ti O3as Ti source are expected to be more competitive than the traditional one for practical applications.Lijun Gong Yuxi Chen Hongjiang Yu Hongbo Liu Caifu Li Zhi-Quan Liu 2014Journal of Materials Science & Technology2014,30,11:3

14敲入亨廷顿基因的猪模型再现了亨廷顿病的选择性神经退化症状显示文摘文章简介亨廷顿舞蹈病(Huntington’s disease, HD)是一种遗传性神经退行性疾病,是由一种编码导致脑细胞死亡的毒性蛋白的基因引起的。尽管转基因小鼠已被广泛用于构建神经退行性疾病模型,但是它们缺乏在人类大脑中观察到的典型神经变性或明显的神经元缺失。Sen Yan Zhuchi Tu Zhaoming Liu Nana Fan Huiming Yang Su Yang Weili Yang Yu Zhao Zhen Ouyang Chengdan Lai Huaqiang Yang Li Li Qishuai Liu Hui Shi Guangqing Xu Heng Zhao Hongjiang Wei Zhong Pei 李世华 赖良学 李晓江 2019科学新闻2019,0,2:0
