| 1 | Advanced Space-based Solar Observatory(ASO-S):an overview显示文摘The Advanced Space-based Solar Observatory(ASO-S)is a mission proposed for the 25 th solar maximum by the Chinese solar community.The scientific objectives are to study the relationships between the solar magnetic field,solar flares and coronal mass ejections(CMEs).Three payloads are deployed:the Full-disk vector Magneto Graph(FMG),the Lyman-αSolar Telescope(LST)and the Hard X-ray Imager(HXI).ASO-S will perform the first simultaneous observations of the photospheric vector magnetic field,non-thermal imaging of solar flares,and the initiation and early propagation of CMEs on a single platform.ASO-S is scheduled to be launched into a 720 km Sun-synchronous orbit in 2022.This paper presents an overview of the mission till the end of Phase-B and the beginning of Phase-C. | Wei-Qun Gan Cheng Zhu Yuan-Yong Deng Hui Li Yang Su Hai-Ying Zhang Bo Chen Zhe Zhang Jian Wu Lei Deng Yu Huang Jian-Feng Yang Ji-Jun Cui Jin Chang Chi Wang Ji Wu Zeng-Shan Yin Wen Chen Cheng Fang Yi-Hua Yan Jun Lin Wei-Ming Xiong Bin Chen Hai-Chao Bao Cai-Xia Cao Yan-Ping Bai Tao Wang Bing-Long Chen Xin-Yu Li Ye Zhang Li Feng Jiang-Tao Su Ying Li Wei Chen You-Ping Li Ying-Na Su Hai-Yan Wu Mei Gu Lei Huang Xue-Jun Tang | 2019 | Research in Astronomy and Astrophysics2019，19，11： | 17 |
| 2 | Highly Efficient Adsorption of Copper Ions by a PVP-Reduced Graphene Oxide Based On a New Adsorptions Mechanism显示文摘Polyvinylpyrrolidone-reduced graphene oxide was prepared by modified hummers method and was used as adsorbent for removing Cu ions from wastewater. The effects of contact time and ions concentration on adsorption capacity were examined. The maximum adsorption capacity of 1689 mg/g was observed at an initial p H value of 3.5 after agitating for 10 min. It was demonstrated that polyvinylpyrrolidone-reduced graphene oxide had a huge adsorption capacity for Cu ions, which was 10 times higher than maximal value reported in previous works. The adsorption mechanism was also discussed by density functional theory. It demonstrates that Cu ions are attracted to surface of reduced graphene oxide by C atoms in reduced graphene oxide modified by polyvinylpyrrolidone through physisorption processes, which may be responsible for the higher adsorption capacity. Our results suggest that polyvinylpyrrolidone-reduced graphene oxide is an effective adsorbent for removing Cu ions in wastewater. It also provides a new way to improve the adsorption capacity of reduced graphene oxide for dealing with the heavy metal ion in wastewater. | Yongji Zhang HuiJuan Chi WenHui Zhang Youyi Sun Qing Liang Yu Gu Riya Jing | 2014 | Nano-Micro Letters2014，6，1： | 9 |

| 4 | Coal analysis using the pulsed neutron generator显示文摘A prototype of elemental analyzer for coal has been developed by using a PFTNA (pulse fast thermalneutron analysis) system. The PFTNA technology is based on the reactions such as (n, γ), (n, n'γ), (n, Pγ), etc. byexamining the characteristic gamma rays emitted. In our prototype a pulsed neutron generator provides 14 MeV pulseneutrons, which contribute to the separation of spectrum Ⅱ (the sum of capture and activation spectrum) fiom spec-trum Ⅰ (the sum of inelastic, capture and activation spectrum), and thus to the measurement of C and O contents incoal. Data management is completed by computer program using the least-square regression method. The experimentin Changshan Power Plant for 3 months showed that the precision of calorific value, whole water, volatile content andash content is 0.5 k J/kg, 1.0 wt%, 2.0 wt% and 1.5 wt%, respectively. | JING Shi-Wei, LIU Lin-Mao, GU De-Shan, QIAO Shuang, SANG Hai-Feng, ZHANG Yong-Xiang, ZHANG Zhong-Hua,CAO Xi-Zheng, TIAN Yu-Bing, CHI Yan-Tao, ZHAO Xin-Hui (The Radiation Technology Institute of the Northeast Normal University, Changchun 130024) | 2003 | Nuclear Science and Techniques2003，14，4： | 6 |
| 5 | A space power system of free piston Stirling generator based on potassium heat pipe显示文摘The power system of a free piston Stirling generator(FPSG)based on potassium heat pipes has been developed in this paper.Thanks to the advantages of long life,high reliability,and high overall thermal efficiency,the FPSG is a promising candidate for nuclear energy,especially in space exploration.In this paper,the recent progress of FPSG based on nuclear reactor for space use was briefly reviewed.A novel FPSG weighted only 4.2 kg was designed,and one dimensional thermodynamic modeling of the FPSG using Sage software was performed to estimate its performance.The experiment results indicated that this FPSG could provide 142.4 W at a thermal-to-electric efficiency of nearly 17.4%.Besides,the power system integrated with four FPSGs and potassium heat pipes was performed and the single machine failure test was conducted.The results show that this system could provide an electrical power of 300 W at an overall thermal efficiency of 7.3%.Thus,it is concluded that this power system is feasible and will have a great prospect for future applications. | Mingqiang LIN Jian MOU Chunyun CHI Guotong HONG Panhe GE Gu HU | 2020 | Frontiers in Energy2020，14，1： | 5 |
| 6 | Nanostructured ZnO for biosensing applications显示文摘Based on the unique properties, nanostructured ZnO could provide a stable immobilization for biomolecules retaining their biological activity. It has been recently developed as a nice candidate for the construction of biosensors with enhanced analytical performance. In this paper, we reviewed the progress in adapting nanostructured ZnO for several predominantly in biosensing applications based on enzymic reaction, immunoreaction, and molecular compitation. We also described several important considerations when working with nanostructured ZnO mainly centered on the fabrications of ZnO and appropriate strategies for biosensor construction (e.g. modified electrodes and multilayered immobilization). | XU ChunXiang YANG Chi GU BaoXiang FANG ShengJiang | 2013 | Chinese Science Bulletin2013，58，21： | 4 |
| 7 | Effect of Morphology for Novel Bainite/Martensite Dual-Phase High Strength Steel on Its Hydrogen Embrittlement Susceptibility显示文摘The susceptibility to hydrogen embrittlement ofbainite/martensite dual-phase high strength steel with different morphologies obtained by the conventional and thermo-mechanical heat treatments has been investigated by means of electrolytic hydrogen charging. The results showed that the finer the microstructure, the lower the sensitivity of steel to hydrogen embrittlement. The fractographic analysis suggested that the fracture mode of the hydrogen-charged specimens is of a mixture of quasicleavage and dimple for both treating processes. The quasicleavage facet of the thermomechanical treated specimen is smaller than that of the conventional heated one, which is probably the reason for reducing the susceptibility to hydrogen embrittlement. Fracture metallographic observations showed that the crack propagates preferentially along bainite/martensite laths boundary, and suggested that the fracture mode is of predominantly lath boundary separation. | CHANG Kai-di GU Jia-lin FANG Hong-sheng BAI Bing-zhe ZHANG Wen-zheng YANG Zhi-gang LIU Dong-yu ZHANG Chi | 2001 | Journal of Iron and Steel Research(International)2001，8，1： | 3 |
| 8 | Side-Channel Analysis for the Authentication Protocols of CDMA Cellular Networks显示文摘Time-division multiple access (TDMA) and code-division multiple access (CDMA) are two technologies used in digital cellular networks. The authentication protocols of TDMA networks have been proven to be vulnerable to side-channel analysis (SCA), giving rise to a series of powerful SCA-based attacks against unprotected subscriber identity module (SIM) cards. CDMA networks have two authentication protocols, cellular authentication and voice encryption (CAVE) based authentication protocol and authentication and key agreement (AKA) based authentication protocol, which are used in different phases of the networks. However, there has been no SCA attack for these two protocols so far. In this paper, in order to figure out if the authentication protocols of CDMA networks are sufficiently secure against SCA, we investigate the two existing protocols and their cryptographic algorithms. We find the side-channel weaknesses of the two protocols when they are implemented on embedded systems. Based on these weaknesses, we propose specific attack strategies to recover their authentication keys for the two protocols, respectively. We verify our strategies on an 8-bit microcontroller and a real-world SIM card, showing that the authentication keys can be fully recovered within a few minutes with a limited number of power measurements. The successful experiments demonstrate the correctness and the effectiveness of our proposed strategies and prove that the unprotected implementations of the authentication protocols of CDMA networks cannot resist SCA. | Chi Zhang Jun-Rong Liu Da-Wu Gu Wei-Jia Wang Xiang-Jun Lu Zheng Guo Hai-Ning Lu | 2019 | Journal of Computer Science & Technology2019，34，5： | 1 |
| 9 | Cold Water in the Lee of the Batanes Islands in the Luzon Strait显示文摘Using satellite remote sensing data and hydrological observation data,this study investigated the cold water in the lee of the Batanes Islands in the Luzon Strait.The formation of cold water in climate is mainly due to the geostrophic heat advection on the east and west sides of the Batanes Islands:the Kuroshio separates into two branches on the east and west sides of the Batanes Islands.These two branches cause two warm tongues by transferring heat from low latitudes to mid-latitudes,and then the two warm tongues lead to the formation of the relatively cold water in the lee of the Batanes Islands.Further study shows that the cold water range has obvious seasonal and inter-annual variations.Except for August,the seasonal variation of the cold water range is caused by the interaction of geostrophic heat advection and net surface heat flux,whereas the low temperature in August in the lee of the Batanes Islands is caused by the island wake effect.The inter-annual of the cold water range is related to the difference in the meridional velocity between the east and west sides of the Batanes Islands,and the correlation coefficient can reach−0.68 at the 95%confidence level. | SUN Ruili ZHAI Fangguo ZHANG Guosheng GU Yanzhen CHI Nianping | 2020 | Journal of Ocean University of China2020，19，6： | 1 |

| 12 | Meticulous Regionalization of Climate Suitability about Spring Potato Planting in Western Guizhou Based on GIS显示文摘[Objective] The study aimed to carry out the regionalization of climate suitability about spring potato planting in Western Guizhou on the basis of GIS technology. [Method] Based on the climatic data of 15 meteorological stations in Western Guizhou during the growing period of spring potato from March to August in 1978-2010, the regionalization indicators of climate suitability about spring potato planting were determined according to the correlation between climatic factors and meteorological yield of spring potato. Afterwards, on the basis of climitic data and corresponding basic geographical information like longitude, latitude, altitude, slope and aspect, the spatial analysis models of division indicators about spring potato planting in Western Guizhou were established by using GIS spatial overlay analysis and used to carry out the township-level regionalization of climate suitability about spring potato planting in Western Guizhou with 100 m×100 m grids. [Result] Based on the relationship between meteorological yield of spring potato and climatic factors in Western Guizhou from 1978 to 2010, eight climatic division indicators, including altitude, average temperature,>10 ℃ active accumulated temperature, precipitation and sunshine hours in the growth stage, average temperature in July, average temperature difference between day and night from July to August, and precipitation from May to July, were chosen for spring potato planting, and each indicator had three levels, namely the most suitable, suitable and sub-suitable. Meanwhile, Western Guizhou was grouped into three areas according to these indicators, including the most suitable area, suitable area and sub-suitable area, and their area accounted for 52%, 45% and 3% of total area of the whole province respectively. [Conclusion] The research could provide scientific references for the production layout and species selection of spring potato in Western Guizhou. | CHI Zai-xiang MO Jian-guo KANG Xue-liang GU Xiao-ping XIAO Jun | 2012 | Meteorological and Environmental Research2012，3，11： | 1 |

| 18 | Direct bandgap engineering with local biaxial strain in few-layer MoS2 bubbles显示文摘Nano Research volume 13,pages2072–2078(2020)Cite this article 211 Accesses Metrics details Abstract Strain engineering provides an important strategy to modulate the optical and electrical properties of semiconductors for improving devices performance with mechanical force or thermal expansion difference.Here,we present the investigation of the local strain distribution over few-layer MoS2 bubbles,by using scanning photoluminescence and Raman spectroscopies.We observe the obvious direct bandgap emissions with strain in the few-layer MoS2 bubble and the strain-induced continuous energy shifts of both resonant excitons and vibrational modes from the edge of the MoS2 bubble to the center(10μm scale),associated with the oscillations resulted from the optical interference-induced temperature distribution.To understand these results,we perform ab initio simulations to calculate the electronic and vibrational properties of few-layer MoS2 with biaxial tensile strain,based on density functional theory,finding good agreement with the experimental results.Our study suggests that local strain offers a convenient way to continuously tune the physical properties of a few-layer transition metal dichalcogenides(TMDs)semiconductor,and opens up new possibilities for band engineering within the 2D plane. | Yang Guo Bin Li Yuan Huang Shuo Du Chi Sun Hailan Luo Baoli Liu Xingjiang Zhou Jinlong Yang Junjie Li Changzhi Gu | 2020 | Nano Research2020，13，8： | 1 |
| 19 | A silk-based self-adaptive flexible opto-electro neural probe显示文摘The combination of optogenetics and electrophysiological recording enables high-precision bidirectional interactions between neural interfaces and neural circuits,which provides a promising approach for the study of progressive neurophysiological phenomena.Opto-electrophysiological neural probes with sufficient flexibility and biocompatibility are desirable to match the low mechanical stiffness of brain tissue for chronic reliable performance.However,lack of rigidity poses challenges for the accurate implantation of flexible neural probes with less invasiveness.Herein,we report a hybrid probe(Silk-Optrode)consisting of a silk protein optical fiber and multiple flexible microelectrode arrays.The Silk-Optrode can be accurately inserted into the brain and perform synchronized optogenetic stimulation and multichannel recording in freely behaving animals.Silk plays an important role due to its high transparency,excellent biocompatibility,and mechanical controllability.Through the hydration of the silk optical fiber,the Silk-Optrode probe enables itself to actively adapt to the environment after implantation and reduce its own mechanical stiffness to implant into the brain with high fidelity while maintaining mechanical compliance with the surrounding tissue.The probes with 128 recording channels can detect high-yield well-isolated single units while performing intracranial light stimulation with low optical losses,surpassing previous work of a similar type.Two months of post-surgery results suggested that as-reported Silk-Optrode probes exhibit better implant-neural interfaces with less immunoreactive glial responses and tissue lesions. | Yu Zhou Chi Gu Jizhi Liang Bohan Zhang Huiran Yang Zhitao Zhou Meng Li Liuyang Sun Tiger H.Tao Xiaoling Wei | 2022 | Microsystems & Nanoengineering2022，8，6： | 1 |
