| 1 | The Chinese Hα Solar Explorer(CHASE) mission: An overview显示文摘The Chinese Hα Solar Explorer(CHASE), dubbed “Xihe”—Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration(CNSA). The CHASE mission is designed to test a newly developed satellite platform and to acquire the spectroscopic observations in the Hα waveband. The Hα Imaging Spectrograph(HIS)is the scientific payload of the CHASE satellite. It consists of two observational modes: raster scanning mode and continuum imaging mode. The raster scanning mode obtains full-Sun or region-of-interest spectral images from 6559.7 to 6565.9 ? and from 6567.8 to 6570.6 ? with 0.024 ? pixel spectral resolution and 1 min temporal resolution. The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations. | Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 7 |
| 2 | SLC1A1-mediated cellular and mitochondrial influx of R-2-hydroxyglutarate in vascular endothelial cells promotes tumor angiogenesis in IDH1-mutant solid tumors显示文摘Muta nt isocitrate dehydrog en ase 1(mlDH1)drives tumorigenesis via produci ng on cometabolite R-2-hydroxyglutarate(R-2-HG)across various tumor types.However,mlDHl in hibitors appear only effective in hematological tumors.The therapeutic ben efit in solid tumors remains elusive,likely due to the complex tumor microenvironment.In this study,we discover that R-2-HG produced by IDH1-mutant tumor cells is preferentially imported into vascular endothelial cells and remodels mitochondrial respiration to promote tumor angiogenesis,conferring a therapeutic vulnerability in IDH1-mutant solid tumors.Mechanistically,SLC1 Alz a Na'-depe ndent glutamate tran sporter that is prefere ntially expressed in en dothelial cells,facilitates the in flux of R-2-HG from the tumor microenvironment into the endothelial cells as well as the intracellular trafficking of R-2-HG from cytoplasm to mitochondria.R-2-HG hijacks SLC1A1 to promote mitochondrial Na^(+)/Ca^(2+)exchange,which activates the mitochondrial respiratory chain and fuels vascular en dothelial cell migratio n in tumor an giogenesis.SLC1A1 deficiency in mice abolishes mlDHl-promoted tumor an giogenesis as well as the therapeutic benefit of mlDHl in hibitor in solid tumors.Moreover,we report that HH2301,a newly discovered mlDHl inhibitor,shows promising efficacy in treating IDH1-mutant cholangiocarcinoma in preclinical models.Together,we identify a new role of SLC1A1 as a gatekeeper of R-2-HG-mediated crosstalk between IDH1-mutant tumor cells and vascular en dothelial cells,and dem on strate the therapeutic potential of mlDHl in hibitors in treating IDH1-muta nt solid tumors via disrupting R-2-HG-promoted tumor angiogenesis. | Xiaomin Wang Ziqi Chen Jun Xu Shuai Tang Nan An Lei Jiang Yixiang Zhang Shaoying Zhang Qingli Zhang Yanyan Shen Shijie Chen Xiaojing Lan Ting Wang Linhui Zhai Siyuwei Cao Siqi Guo Yingluo Liu Aiwei Bi Yuehong Chen Xiameng Gai Yichen Duan Ying Zheng Yixian Fu Yize Li Liang Yuan Linjiang Tong Kun Mo Mingcheng Wang Shu-Hai Lin Minjia Tan Cheng Luo Yi Chen Jia Liu Qiansen Zhang Leping Li Min Huang | 2022 | Cell Research2022，32，7： | 2 |
| 3 | Ultrasound-driven BaTiO_(3) nanorobots patching immunologic barrier to cure chronic rheumatoid arthritis显示文摘The disruption and reconstruction of the TREM2^(+) tissue resident macrophage(TRM)barrier on the surface of synovial lining play a key role in the activation and'remission'of rheumatoid arthritis(RA),which engender the prediction of this immunologic barrier as a potential driver for the achievement of'cure'in RA.However,strategies to promote the reconstruction of this barrier have not been reported,and the effect of patching this barrier remains unidentified.On the other hand,appropriate piezoelectric stimulation can reprogram macrophages,which has never been exerted on this barrier TRM yet.Herein,we design piezoelectric tetragonal BaTiO_(3)(BTO)ultrasound-driven nanorobots(USNRs)by the solvothermal synthesis method,which demonstrates satisfactory electro-mechanical conversion effects,paving the way to generate controllable electrical stimulation under ultrasound to reprogram the barrier TRM by minimally invasive injection into joint cavity.It is demonstrated that the immunologic barrier could be patched by this USNR effectively,thereby eliminating the hyperplasia of vessels and nerves(HVN)and synovitis.Additionally,TREM2 deficiency serum-transfected arthritis(STA)mice models are applied and proved the indispensable role of TREM2 in RA curing mediated by USNR.In all,our work is an interesting and important exploration to expand the classical tetragonal BTO nanoparticles in the treatment of autoimmune diseases,providing a new idea and direction for the biomedical application of piezoelectric ceramics. | Le Jiang Yifan Wang Chunlin Liu Nan Xu Wenshuo Li Lei Wang Yixian Wu Jingyun Wang Zhijun He Fengbo Sun Lingyun Zhao Qiong Wu Xiumei Wang Huihui Yuan Xiaohui Wang Xiaodan Sun | 2023 | Journal of Advanced Ceramics2023，12，5： | 0 |
| 4 | Concentrated ternary ether electrolyte allows for stable cycling of a lithium metal battery with commercial mass loading high-nickel NMC and thin anodes显示文摘A new concentrated ternary salt ether-based electrolyte enables stable cycling of lithium metal battery(LMB)cells with high-mass-loading(13.8 mg cm^(−2),2.5 mAh cm^(−2))NMC622(LiNi_(0.6)Co_(0.2)Mn_(0.2)O_(2))cathodes and 50μm Li anodes.Termed“CETHER-3,”this electrolyte is based on LiTFSI,LiDFOB,and LiBF4 with 5 vol%fluorinated ethylene carbonate in 1,2-dimethoxyethane.Commer-cial carbonate and state-of-the-art binary salt ether electrolytes were also tested as baselines.With CETHER-3,the electrochemical performance of the full-cell battery is among the most favorably reported in terms of high-voltage cycling stability.For example,LiNi_(x)Mn_(y)Co_(1-x-y)O_(2)(NMC)-Li metal cells retain 80%capacity at 430 cycles with a 4.4 V cut-off and 83%capacity at 100 cycles with a 4.5 V cut-off(charge at C/5,discharge at C/2).According to simulation by density functional theory and molecular dynamics,this favorable performance is an outcome of enhanced coordination between Li^(+)and the solvent/salt molecules.Combining advanced microscopy(high-resolution transmission electron microscopy,scanning electron microscopy)and surface science(X-ray photoelectron spectroscopy,time-of-fight secondary ion mass spectroscopy,Fourier-transform infrared spectroscopy,Raman spectroscopy),it is demonstrated that a thinner and more stable cathode electrolyte interphase(CEI)and solid electrolyte interphase(SEI)are formed.The CEI is rich in lithium sulfide(Li_(2)SO_(3)),while the SEI is rich in Li_(3)N and LiF.During cycling,the CEI/SEI suppresses both the deleterious transformation of the cathode R-3m layered near-surface structure into disordered rock salt and the growth of lithium metal dendrites. | Jun Yang Xing Li Ke Qu Yixian Wang Kangqi Shen Changhuan Jiang Bo Yu Pan Luo Zhuangzhi Li Mingyang Chen Bingshu Guo Mingshan Wang Junchen Chen Zhiyuan Ma Yun Huang Zhenzhong Yang Pengcheng Liu Rong Huang Xiaodi Ren David Mitlin | 2023 | Carbon Energy2023，5，3： | 0 |
