| 1 | Cross-calibration on the electromagnetic field detection payloads of the China Seismo-Electromagnetic Satellite显示文摘The China Seismo-Electromagnetic Satellite(CSES)deploys three payloads to detect the electromagnetic environment in the ionosphere.The tri-axial fluxgate magnetometers(FGM),as part of the high precision magnetometer(HPM),measures the Earth magnetic vector field in a frequency range from direct current(DC)to 15 Hz.The tri-axial search coil magnetometer(SCM)detects the alternating current(AC)related magnetic field in a frequency range from several Hz to 20 k Hz,and the electric field detector(EFD)measures the spatial electric field in a broad frequency band from DC to 3.5 MHz.This work mainly crosscalibrates the consistency of these three payloads in their overlapped detection frequency range and firstly evaluates CSES’s timing system and the sampling time differences between EFD and SCM.A sampling time synchronization method for EFD and SCM waveform data is put forward.The consistency between FGM and SCM in the ultra-low-frequency(ULF)range is validated by using the magnetic torque(MT)signal as a reference.A natural quasiperiodic electromagnetic wave event verifies SCM and EFD’s consistency in extremely low-frequency and very low-frequency(ELF/VLF)bands.This cross-calibration work is helpful to upgrade the data quality of CSES and brings valuable insights to similar electromagnetic detection solutions by low earth orbit satellites. | ZHIMA Zeren ZHOU Bin ZHAO ShuFan WANG Qiao HUANG JianPing ZENG Li LEI JunGang CHEN Yu LI Cheng YANG DeHe SUN XiaoYing MIAO YuanQing ZHU XingHong SHEN XuHui | 2022 | Science China(Technological Sciences)2022，65，6： | 3 |

| 4 | Facet-Controlled LiMn_(2)O_(4)/C as Deionization Electrode with Enhanced Stability and High Desalination Performance显示文摘Battery materials as emerging capacitive deionization electrodes for desalination have better salt removal capacities than traditional carbon-based materials.LiMn_(2)O_(4),a widely used cathode mate-rial,is difficult to utilize as a deionization electrode due to its structural instability upon cycling and Mn dissolution in aqueous-based electrolytes.Herein,a facile and low-cost ball-milling routine was proposed to prepare a LiMn_(2)O_(4)material with highly exposed(111)facets.The prepared electrode exhibited relatively low dissolution of Mn during cycling,which shows its long cycle stability.In the hybrid capacitive deionization system,the LiMn_(2)O_(4)/C electrode delivered a high desalination capacity of 117.3 mg g^(−1) without obvious capacity decay at a voltage of 1.0 V with a 20 mM initial salt concentration.In addition,the exposed(111)facets significantly alleviated Mn ion dissolution,which also enhanced the structural steadiness. | Yuxin Jiang Liyuan Chai Dehe Zhang Fangping Ouyang Xiangyuan Zhou Sikpaam IAlhassan Sailin Liu Yingjie He Lvji Yan Haiying Wang Wenchao Zhang | 2022 | Nano-Micro Letters2022，14，11： | 1 |
| 5 | Stability validation on the VLF waveform data of the China-Seismo-Electromagnetic Satellite显示文摘The China-Seismo-Electromagnetic Satellite(CSES),which was launched in February 2018,carries the search coil magnetometer(SCM)and the electric field detector(EFD)to realize the high-resolution electromagnetic field and wave detection in the upper ionosphere.Due to the complexity and variability of the ionospheric environment,the stability of such a high sampling rate and high-precision electromagnetic field detection systems is always an essential link in data processing and the scientific application of CSES.This work evaluates the stability of the very-low-frequency(VLF)band detection by validating the systemic sampling-time differences between SCM and EFD in the VLF burst-mode observations.The optimal waveform data preprocessing method is put forward according to the noise levels of the VLF burst-mode observation and the inherent design characteristics of EFD.The VLF waveform data of EFD is rebuilt by filling the data gaps among the sampling sub-periods,making it with a similar sample length to SCM.Then by precisely intercepting the maximum and minimum values of the burst-mode waveforms,the variation of the sampling-time difference between EFD and SCM is statistically evaluated.Results show that during the three years'operation,the sampling-time difference between EFD and SCM predominately keeps below 0.5 s,indicating good stability of EFD and SCM on orbit.Then we developed an automatic synchronization tool based on the similarity function and STA/LTA(short time average over long time average)characteristic function.This tool can effectively realize the precise synchronization between SCM and EFD in the VLF burst-mode observation.This work is helpful to upgrade the data quality of CSES and provides technical support for electromagnetic wave propagation studies. | YANG DeHe ZHIMA ZeRen WANG Qiao HUANG JianPing WANG XiuYing ZHANG ZhenXia ZHAO ShuFan GUO Feng CHENG WanLi LU HengXin SHEN XuHui | 2022 | Science China(Technological Sciences)2022，65，12： | 1 |
| 6 | Current Status and Main Scientific Outcomes of the CSES Mission显示文摘This report briefly introduces the current status of the CSES(China Seismo-Electromagnetic Satellite)mission which includes the first satellite CSES 01 in-orbit(launched in February 2018),and the second satellite CSES 02(will be launched in 2023)under development.The CSES 01 has been steadily operating in orbit for over four years,providing abundant global geophysical field data,including the background geomagnetic field,the electromagnetic field and wave,the plasma(in-situ and profile data),and the energetic particles in the ionosphere.The CSES 01 platform and the scientific instruments generally perform well.The data validation and calibration are vital for CSES 01,for it aims to monitor earthquakes by extracting the very weak seismic precursors from a relatively disturbing space electromagnetic environment.For this purpose,we are paying specific efforts to validate data quality comprehensively.From the CSES 01 observations,we have obtained many scientific results on the ionosphere electromagnetic environment,the seismo-ionospheric disturbance phenomena,the space weather process,and the Lithosphere-Atmosphere-Ionosphere coupling mechanism. | ZEREN Zhima HUANG Jianping LIU Dapeng YANG Yanyan YAN Rui ZHAO Shufan ZHANG Zhenxia LIN Jian CUI Jing CHU Wei WANG Qiao LU Hengxin XU Song GUO Feng YANG Dehe ZHOU Na LIU Qinqin HUANG He WANG Jie TAN Qiao LI Wenjing LÜFangxian ZHU Keying SHEN Xuhui | 2022 | 空间科学学报2022，42，4： | 0 |
