| 1 | Preliminary Scientific Results of Chang'E-1 Lunar Orbiter:Based on Payloads Detection Data in the First Phase显示文摘Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT(Beijing Time) Oct.24,2007.It is the first step of its ambitious three-stage moon program,a new milestone in the Chinese space exploration history.The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension(3D) stereo images of the lunar surface,to analyze the distribution and abundance of elements on the surface,to investigate the thickness of lunar soil,evaluate helium-3 resources and other characteristics,and to detect the space environment around the moon.To achieve the above four mission objectives,eight sets of scientific instruments are chosen as the payloads of the lunar orbiter,including a CCD stereo camera(CCD),a Sagnac-based interferometer spectrometer(ⅡM),a Laser Altimeter(LAM),a Microwave Radiometer(MRM),a Gamma-Ray Spectrometer(GRS),an X-ray spectrometer(XRS),a High-Energy Particle Detector(HPD),and two Solar Wind Ion Detectors(SWID).The detected data of the payloads show that all payloads work well.This paper introduces the status of payloads in the first phase and preliminary scientific results. | OUYANG Ziyuan JIANG Jingshan LI Chunlai SUN Huixian ZOU Yongliao LIU Jianzhong LIU Jianjun ZHAO Baochang REN Xin YANG Jianfeng ZHANG Wenxi WANG Jianyu MOU Lingli CHANG Jin ZHANG Liyan WANG Huanyu LI Yongquan ZHANG Xiaohui ZHENG Yongchun WANG Shijin BIAN Wei | 2008 | 空间科学学报2008，28，5： | 24 |
| 2 | A Review on Metal-Organic Framework-Derived Porous Carbon-Based Novel Microwave Absorption Materials显示文摘The development of microwave absorption materials(MAMs) is a considerable important topic because our living space is crowed with electromagnetic wave which threatens human’s health.And MAMs are also used in radar stealth for protecting the weapons from being detected.Many nanomaterials were studied as MAMs,but not all of them have the satisfactory performance.Recently,metal-organic frameworks(MOFs) have attracted tremendous attention owing to their tunable chemical structures,diverse properties,large specific surface area and uniform pore distribution.MOF can transform to porous carbon(PC) which is decorated with metal species at appropriate pyrolysis temperature.However,the loss mechanism of pure MOF-derived PC is often relatively simple.In order to further improve the MA performance,the MOFs coupled with other loss materials are a widely studied method.In this review,we summarize the theories of MA,the progress of different MOF-derived PC-based MAMs,tunable chemical structures incorporated with dielectric loss or magnetic loss materials.The different MA performance and mechanisms are discussed in detail.Finally,the shortcomings,challenges and perspectives of MOF-derived PC-based MAMs are also presented.We hope this review could provide a new insight to design and fabricate MOF-derived PC-based MAMs with better fundamental understanding and practical application. | Zhiwei Zhang Zhihao Cai Ziyuan Wang Yaling Peng Lun Xia Suping Ma Zhanzhao Yin Yi Huang | 2021 | Nano-Micro Letters2021，13，4： | 17 |
| 3 | Characteristics of the lunar samples returned by the Chang'E-5 mission显示文摘Forty-five years after the Apollo and Luna missions returned lunar samples,China's Chang’E-5(CE-5)mission collected new samples from the mid-latitude region in the northeastern Oceanus Procellarum of the Moon.Our study shows that 95%of CE-5 lunar soil sizes are found to be within the range of 1.40-9.35μm,while 95%of the soils by mass are within the size range of 4.84-432.27μm.The bulk density,true density and specific surface area of CE-5 soils are 1.2387 g/cm^(3),3.1952 g/cm^(3) and 0.56 m^(2)/g,respectively.Fragments from the CE-5 regolith are classified into igneous clasts(mostly basalt),agglutinate and glass.A few breccias were also found.The minerals and compositions of CE-5 soils are consistent with mare basalts and can be classified as low-Ti/low-Al/low-K type with lower rare-earth-element contents than materials rich in potassium,rare earth element and phosphorus.CE-5 soils have high FeO and low Mg index,which could represent a new class of basalt. | Chunlai Li Hao Hu Meng-Fei Yang Zhao-Yu Pei Qin Zhou Xin Ren Bin Liu Dawei Liu Xingguo Zeng Guangliang Zhang Hongbo Zhang Jianjun Liu Qiong Wang Xiangjin Deng Caijin Xiao Yonggang Yao Dingshuai Xue Wei Zuo Yan Su Weibin Wen Ziyuan Ouyang | 2022 | National Science Review2022，9，2： | 12 |
| 4 | Chang'E-1 Lunar Mission:An Overview and Primary Science Results显示文摘Chang'E-1 is the first lunar mission in China,which was successfully launched on Oct.24th,2007.It was guided to crash on the Moon on March 1,2009,at 52.36°E,1.50°S,in the north of Mare Fecunditatis.The total mission lasted 495 days,exceeding the designed life-span about four months.1.37Terabytes raw data was received from Chang'E-1.It was then processed into 4Terabytes science data at different levels.A series of science results have been achieved by analyzing and applicating these data,especially 'global image of the Moon of China's first lunar exploration mission'.Four scientific goals of Chang'E-1 have been achieved.It provides abundant materials for the research of lunar sciences and cosmochemistry.Meanwhile these results will serve for China's future lunar missions. | Ouyang Ziyuan Li Chunlai Lu Chang Liu Jianzhong Zou Yongliao Zhang Hongbo Jianjun Zuo Wei Su Yah Wen Weibin Bian Wei Zhao Baochang Wang Jianyu Yang Jianfeng Chang Jin Wang Huanyu Zhang Xiaohui Wang Shijin Wang Min Ren Xin Mu Lingli Kong Deqing Wang Xiaoqian Wang Fang Geng Liang Zhang Zhoubin Zheng Lei Zhu Xinying Zheng Yongchun Li Junduo Zou Xiaoduan Xu Chun Shi Shuobiao Gao Yifei Gao Guannan | 2010 | 空间科学学报2010，30，5： | 11 |
| 5 | Serpentinization, abiogenic organic compounds, and deep life显示文摘The hydrocarbons and other organic compounds generated through abiogenic or inorganic processes are closely related to two science subjects,i.e.,energy resources and life’s origin and evolution.'The earth’s primordial abiogenic hydrocarbon theory'and'the serpentinization of abiogenic hydrocarbon theory'are the two mainstream theories in the field of related studies.Serpentinization generally occurs in slow expanding mid-ocean ridges and continental ophiolites tectonic environment,etc.The abiogenic hydrocarbons and other organic compounds formed through the serpentinization of ultramafic rocks provide energy and raw materials to support chemosynthetic microbial communities,which probably was the most important hydration reaction for the origin and early evolution of life.The superposition of biological and abiological processes creates big challenge to the identification of the abiogenic organic materials in serpentinite-hosted ecosystem.Whether abiotic(inorganic)process can form oil and gas resource is a difficult question that has been explored continuously by scientific community for more than a century but has not yet been solved.However,some important progress has been made.The prospecting practice of abiogenic hydrocarbons in commercial gases from the Songliao Basin,China,provides an important example for exploring abiogenic natural gas resources. | WANG XianBin OUYANG ZiYuan ZHUO ShengGuang ZHANG MingFeng ZHENG GuoDong WANG YongLi | 2014 | Science China Earth Sciences2014，57，5： | 11 |
| 6 | Methods for Shale Gas Play Assessment: A Comparison between Silurian Longmaxi Shale and Mississippian Barnett Shale显示文摘Based on field work, organic geochemical analyses and experimental testing, a six-property assessment method for shale gas is proposed. These six properties include organic matter properies, lithofacies, petrophysical properties, gas content, brittleness and local stress field. Due to the features of continuous distribution over a large area and low resource abundance in shale plays, a sweet spot should have these following properties:(a) TOC>2%;(b) brittle minerals content(>40%) and clay minerals(<30%);(c) Ro(>1.1%);(d) porosity(>2%) and permeability(>0.000 1 m D), and(e) effective thickness(30–50 m). Applying these criteria in the Sichuan Basin, the Silurian Longmaxi shale consists of four prospecting sweet spots, including blocks of Changning, Weiyuan, Zhaotong and Fushun-Yongchuan. Although these four blocks have some similarities, different features were usually observed. After comprehensive analyses using the six-property assessment method, the Fushun-Yongan Block ranks the most favorable sweet spot, followed by the Weiyuan Block. For the other two blocks, the Changning Block is better than the Zhaotong Block. By comparing with the Mississippian Barnett shale, characteristics that are crucial for a high-yielding in the Sichuan Basin include a high content of organic matter(TOC>2.5%), a moderate thermal maturity(Ro=0.4%–2%), a high content of brittle minerals(quartz: 30%–45%), a high gas content(>2.5 m3?t-1), and types I and II1 kerogen. | Songqi Pan Caineng Zou Zhi Yang Dazhong Dong Yuman Wang Shufang Wang Songtao Wu Jinliang Huang Qun Liu Dule Wang Ziyuan Wang | 2015 | Journal of Earth Science2015，26，2： | 10 |
| 7 | Study of Sr–Ca–Si-based scaffolds for bone regeneration in osteoporotic models显示文摘Bone tissue engineering has emerged as a promising alternative therapy for patients who suffer bone fractures or defects caused by trauma,congenital diseases or tumours.However,the reconstruction of bone defects combined with osteoporosis remains a great challenge for clinicians and researchers.Based on our previous study,Ca–Si-based bioceramics(MSCs)showed enhanced bone formation capabilities under normal conditions,and strontium was demonstrated to be therapeutic in promoting bone quality in osteoporosis patients.Therefore,in the present study,we attempted to enlarge the application range of MSCs with Sr incorporation in an osteoporotic bone regeneration model to evaluate whether Sr could assist in regeneration outcomes.In vitro readout suggested that Sr-incorporated MSC scaffolds could enhance the expression level of osteogenic and angiogenic markers of osteoporotic bone mesenchymal stem cells(OVX BMSCs).Animal experiments showed a larger new bone area;in particular,there was a tendency for blood vessel formation to be enhanced in the Sr-MSC scaffold group,showing its positive osteogenic capacity in bone regeneration.This study systematically illustrated the effective delivery of a low-cost therapeutic Sr agent in an osteoporotic model and provided new insight into the treatment of bone defects in osteoporosis patients. | Qianju Wu Xiao Wang Fei Jiang Ziyuan Zhu Jin Wen Xinquan Jiang | 2020 | International Journal of Oral Science2020，12，3： | 9 |
| 8 | Petrology and mineral chemistry of new ureilites found in Grove Mountains,Antarctica显示文摘Petrography and mineral chemistry of two new ureilites, GRV 021512 and 022931, from the Grove Mountains, Antarctica, are reported in this paper. GRV 021512 exhibits a typical ureilite texture, and consists of 48.3% olivine, 9.4% pigeonite and 38.1% carbo- naceous interstitial material and/or reduction product. GRV 022931 has a cataclastic porphyritic texture, and consists of 19.1% olivine and 14.1% pigeonite embedded in 66.3% carbonaceous interstitial material and/or reduction product. The coarse-grained olivine and pigeonite in both meteorites have homogeneous cores, and they are FeO-rich within the range of the ferroan subgroup (subgroup I) of olivine-pigeonite ureilites. All olivine grains of the meteorites show reduction zones along boundaries and cracks. Abundant diamond coexists with graphite as graphite-rich patches and veins in the carbonaceous interstitial material. Petrogenesis of both meteorites and the origin of diamond are discussed. | Bingkui Miao Yangting Lin Guiqin Wang Daode Wang Ziyuan Ouyang | 2008 | Progress in Natural Science:Materials International2008，18，4： | 8 |
| 9 | Lignocellulosic biomass as sustainable feedstock and materials for power generation and energy storage显示文摘Lignocellulosic biomass has attracted great interest in recent years for energy production due to its renewability and carbon-neutral nature.There are various ways to convert lignocellulose to gaseous,liquid and solid fuels via thermochemical,chemical or biological approaches.Typical biomass derived fuels include syngas,bio-gas,bio-oil,bioethanol and biochar,all of which could be used as fuels for furnace,engine,turbine or fuel cells.Direct biomass fuel cells mediated by various electron carriers provide a new direction of lignocellulose conversion.Various metal and non-metal based carriers have been screened for mediating the electron transfer from biomass to oxygen thus generating electricity.The power density of direct biomass fuel cells can be over 100 mW cm^(-2),which shows promise for practical applications.Lignocellulose and its isolated components,primarily cellulose and lignin,have also been paid considerable attention as sustainable carbonaceous materials for preparation of electrodes for supercapacitors,lithium-ion batteries and lithium-sulfur batteries.In this paper,we have provided a state-of-the-art review on the research progress of lignocellulosic biomass as feedstock and materials for power generation and energy storage focusing on the chemistry aspects of the processes.It was recommended that process integration should be performed to reduce the cost for thermochemical and biological conversion of lignocellulose to biofuels,while efforts should be made to increase efficiency and improve the properties for biomass fuelled fuel cells and biomass derived electrodes for energy storage. | Fangqian Wang Denghao Ouyang Ziyuan Zhou Samuel JPage Dehua Liu Xuebing Zhao | 2021 | Journal of Energy Chemistry2021，30，6： | 8 |

| 11 | Rapid growth of a long-seed KDP crystal显示文摘To reduce the seed length while maintaining the advantages of the cuboid KDP-type crystal,a long-seed KDP crystal with size 471 mm×480 mm×400 mm is rapidly grown.With almost the same high cutting efficiency to obtain third harmonic generation oriented samples,this long-seed KDP-type crystal can be grown with a shorter seed than that of the cuboid KDP-type crystal.The full width at half maximum of the high-resolution X-ray diffraction of the(200)crystalline face is 28.8 arc seconds,indicating that the long-seed KDP crystal has good crystalline quality.In the wavelength range of 377–1022 nm,the transmittance of the long-seed KDP crystal is higher than 90%.The fluence for the 50%probability of laser-induced damage(LID)is 18.5 J/cm^2(3 ns,355 nm).Several test points survive when the laser fluence exceeds 30 J/cm^2(3 ns,355 nm),indicating the good LID performance of the long-seed KDP crystal.At present,the growth of a long-seed DKDP crystal is under way. | Duanyang Chen Bin Wang Hu Wang Xiangyu Zhu Ziyuan Xu Yuanan Zhao Shenghao Wang Kaizao Ni Lili Zheng Hui Zhang Hongji Qi Jianda Shao | 2020 | High Power Laser Science and Engineering2020，8，1： | 5 |
| 12 | Evidence of Nd isotope for unhomogeneity and origin of upper mantle of North China platform显示文摘Based on isptopic age of Sm-Nd and its initial composition and its evolution obtained during the recent years of archean metamorphic magnesio-ferro the vocanics of upper mantle of the North China platform, it is concluded that the isotopic composition of Archean upper mantle of the North China platform is not homogeneous, and values of /Nd don not change regularly through the whole Archean; in contrast, they present obvious differences in different regions. All this demands that the unhomogeneity of Archean upper mantle of the North China platform inherits initial unhomogeneity of origin, and the origin of the North China platform should contribute to uneven accumulation of planetesimals. | Jianzhong Liu Ziyuan Ouyang Fuqin Zhang Shijie Wang | 1999 | Chinese Science Bulletin1999，44，6： | 5 |
| 13 | Introduction to the Payloads and the Initial Observation Results of Chang'E-1显示文摘Chang'E-1,the orbiter circling the moon 200km above the moon surface,is the first Chinese Lunar exploration satellite.The satellite was successfully launched on 24th October 2007.There are 8 kinds of scientific payloads onboard,including the stereo camera,the laser altimeter,the Sagnac-based interferometer image spectrometer,the Gamma ray spectrometer,the X-ray spectrom-eter,the microwave radiometer,the high energy particle detector,the solar wind plasma detector and a supporting payload data management system.Chang'E-1 opened her eyes to look at the moon and took the first batch of lunar pictures after her stereo camera was switched on in 20th November 2007.Henceforth all the instruments are successfully switched on one by one.After a period of parameter adjustment and initial check out,all scientific instruments are now in their normal operating phase.In this paper,the payloads and the initial observation results are introduced. | SUN Huixian WU Ji DAI Shuwu ZHAO Baochang SHU Rong CHANG Jin WANG Huanyu ZHANG Xiaohui REN Qiongying CHEN Xiaomin OUYANG Ziyuan ZOU Yongliao | 2008 | 空间科学学报2008，28，5： | 4 |
| 14 | Modified accumulation of selected heavy metals in Bt transgenic rice显示文摘Safety assessment of genetically modified crops generally does not take into account the potential hazard of altered patterns of heavy metal accumulation in plants. A pot experiment was conducted under greenhouse conditions to evaluate the impact of heavy metal amendments on the accumulation of Cd, Cu, Pb and Zn in a Bt transgenic rice Ke-Ming-Dao (KMD) and its wild-type Xiushui 11 (Xs11). In control soils, significant difference was only found in contents of Cu (p < 0.01) and Pb (p < 0.05) in straw between KMD and Xs11. At three levels of Cd amendments (5, 10, and 20 mg/kg), the Cd contents in grain and straw of KMD were significantly higher than those of Xs11, and all grain Cd contents were significantly higher than the International Criteria (0.2-0.4 mg/kg) as specified by the Codex Alimentarius Commission (CAC). These results implied that it may be unsafe for growing Bt transgenic rice in heavily Cd-polluted areas. No significant difference in Zn was found between the two varieties with the exception of roots at Zn amendment level of 600 mg/kg, while Pb contents in KMD were much higher in the straw at the lead amendment level of 1000 mg/kg and in the root at 250 mg Pb/kg. Data on the heavy metal accumulation patterns for the genetically modified rice may be used for the selection of growing areas as well as for plant residue management for Bt rice. | WANG Haiyan, HUANG Jianzhong, YE Qingfu, WU Dianxing, CHEN Ziyuan Institute of Nuclear Agricultural Sciences, Key Laboratory of Nuclear Agricultural Sciences of Ministry of Agriculture and Zhejiang Province, Zhejiang University, Hangzhou 310029, China | 2009 | Journal of Environmental Sciences2009，21，11： | 3 |
| 15 | Empirical analysis of network measures for predicting high severity software faults显示文摘Network measures are useful for predicting fault-prone modules. However, existing work has not distinguished faults according to their severity. In practice, high severity faults cause serious problems and require further attention. In this study, we explored the utility of network measures in high severity faultproneness prediction. We constructed software source code networks for four open-source projects by extracting the dependencies between modules. We then used univariate logistic regression to investigate the associations between each network measure and fault-proneness at a high severity level. We built multivariate prediction models to examine their explanatory ability for fault-proneness, as well as evaluated their predictive effectiveness compared to code metrics under forward-release and cross-project predictions. The results revealed the following:(1) most network measures are significantly related to high severity fault-proneness;(2) network measures generally have comparable explanatory abilities and predictive powers to those of code metrics; and(3) network measures are very unstable for cross-project predictions. These results indicate that network measures are of practical value in high severity fault-proneness prediction. | Lin CHEN Wanwangying MA Yuming ZHOU Lei XU Ziyuan WANG Zhifei CHEN Baowen XU | 2016 | Science China Earth Sciences2016，59，12： | 3 |

| 20 | Interstitial copper-doped edge contact for n-type carrier transport in black phosphorus显示文摘Black phosphorus(BP)has been shown as a promising two-dimensional(2D)material for electronic devices owing to its high carrier mobility.To realize complementary electronic circuits with 2D materials,it is important to fabricate both n-type and p-type transistors with the same channel material.By engineering the contact region with copper(Cu)-doped BP,here we demonstrate an n-type carrier transport in BP field-effect transistors(FETs),which usually exhibit strongly p-type characteristics.Cu metal atoms are found to severely penetrate into the BP flakes,which forms interstitial Cu(Cuint)-doped edge contact and facilitates the electron transport in BP.Our BP FETs in backgated configuration exhibit n-type dominant characteristics with a high electron mobility of^138 cm^2 V^−1 s^−1 at room temperature.The Schottky barrier height for electrons is relatively low because of the edge contact between Cuint-doped BP and pristine BP channel.The contact doping of BP by highly mobile Cu atoms gives rise to n-type transport property of BP FETs.Furthermore,we demonstrate a p-n junction on the same BP flake with asymmetric contact.This strategy on contact engineering can be further extended to other 2D materials. | Ziyuan Lin Jingli Wang Xuyun Guo Jiewei Chen Chao Xu Mingqiang Liu Bilu Liu Ye Zhu Yang Chai | 2019 | InfoMat2019，1，2： | 2 |
