| 1 | Antimony speciation in the environment:Recent advances in understanding the biogeochemical processes and ecological effects显示文摘Antimony(Sb) is a toxic metalloid, and its pollution has become a global environmental problem as a result of its extensive use and corresponding Sb-mining activities. The toxicity and mobility of Sb strongly depend on its chemical speciation. In this review, we summarize the current knowledge on the biogeochemical processes(including emission, distribution,speciation, redox, metabolism and toxicity) that trigger the mobilization and transformation of Sb from pollution sources to the surrounding environment. Natural phenomena such as weathering, biological activity and volcanic activity, together with anthropogenic inputs, are responsible for the emission of Sb into the environment. Sb emitted in the environment can adsorb and undergo redox reactions on organic or inorganic environmental media, thus changing its existing form and exerting toxic effects on the ecosystem. This review is based on a careful and systematic collection of the latest papers during 2010–2017 and our research results, and it illustrates the fate and ecological effects of Sb in the environment. | Mengchang He Ningning Wang Xiaojing Long Chengjun Zhang Congli Ma Qianyun Zhong Aihua Wang Ying Wang Aneesa Pervaiz Jun Shan | 2019 | Journal of Environmental Sciences2019，31，1： | 40 |
| 2 | Status quo of soil petroleum contamination and evolution of bioremediation显示文摘Along with the rapid development of oil industries internationally,petroleum prospecting and exploitation activities are growing intensively.Especially in China,with the fastest economic growth in the world and shortage of petroleum resources,we are leading the practices of petroleum deep exploitation.Obviously,the risk of damage to the natural environment from these activities is high.Oil contamination in soils and groundwater is becoming a big issue along with pesticide pollution,which makes organic pollution prevention and control (OPPC) much more complex.In this paper,based on recent research on oil-contaminated soil at home and abroad,we make comments on the remediation technologies for polluted soil,emphasizing bioremediation techniques and degradation mechanisms in order to push forward research into bound organic pollution prevention and control (OPPC),especially in China. | Du Weidong Wan Yunyang Zhong Ningning Fei Jiajia ZhangZhihuan Chen Lijun Hao Jiming | 2011 | Petroleum Science2011，8，4： | 19 |
| 3 | Correlation of burial organic carbon and paleoproductivity in the Mesoproterozoic Hongshuizhuang Formation, northern North China显示文摘In general, total organic carbon (TOC) is directly used as a proxy for paleoproductivity, however, it is not only affected by paleoproductivity, but also controlled by redox conditions and terrigenous detrital matter influx. Major and trace elements were analysed with the purpose of investigating the redox potential and paleoproductivity during deposition of the Hongshuizhuang Formation. In the present study, C-S relationship, V/Cr ratio and Mo concentration indicate that the dolomites were deposited in oxic environments, however, most of the black shales were accumulated in euxinic environments. P/Ti values in the Hongshuizhuang samples can be compared with those in the Japanese Ubara Permian-Triassic section which were regarded to be deposited under a moderate to high paleoproductivity. Ba/Al values are slightly lower than that of the laminated sediments from the continental margins of Central California (CCAL) which were thought to be accumulated under a high paleoproductivity. These results indicate that the paleoproductivity was moderate to high during deposition of the Hongshuizhuang Formation. Burial organic carbon shows positive correlations with V/Cr and Mo, but shows only weakly or no correlation with P/Ti and Ba/Al, respectively, suggesting that although the paleoproductivity was moderate to high during deposition of the Hongshuizhuang Formation, its organic-rich sediments were predominantly controlled by redox conditions and had no direct relationship with paleoproductivity. | LUO QingYong ZHONG NingNing ZHU Lei WANG YanNian QIN Jing QI Lin ZHANG Yi MA Yong | 2013 | Chinese Science Bulletin2013，58，11： | 17 |
| 4 | New progress and future prospects of CBM exploration and development in China显示文摘Efforts to speed up China's coal bed methane (CBM) exploration developments related to production safety, optimization of energy structures, prevention of energy waste and reduction of greenhouse gas emissions are all of great significance. In order to strengthen CBM exploration and development in China and to encourage increased growth in the CBM industry, we firstly give a general overview of the recent technological innovations and other developments in CBM exploration in the U.S., Canada and other countries. Using this background information as the starting point, we further present observations and analyses of CBM exploration and development, preferential policies, technical support and implications of R&D for CBM development in China. The results show that the problems related to CBM exploration technology development and lack of a complete set of management policies are still the major issues slowing down the growth of domestic CBM industry. Development of resource exploration and technology, R&D and establishment of favorable government policy to support the industry and the creation of a relevant information platform, etc. are finally recommended. | Vun Jian Xu Fengyin Liu Lin Zhong Ningning Wu Xiaobin | 2012 | International Journal of Mining Science and Technology2012，22，3： | 11 |
| 5 | Study of simulation experiments on the TSR system and its effect on the natural gas destruction显示文摘The TSR process may be one of the reasons to result in the natural gas destruction in deep carbonate reservoirs. The work on this field has been the subject of much research in recent years. In this paper, thermal simulation experiments on the reaction of CH4-CaSO4 were carried out using autoclave at high temperature and high pressure. The products were charac-terized by some advanced analytical methods. The thermodynamics and kinetics were discussed and the reaction mechanism was investigated tentatively. It is found that the reaction can pro-ceed spontaneously to produce H2S, H2O and CaCO3 as the main products at the temperature range of 550―700℃ . The activation energy and geological reaction rate calculated from the ki-netic model can be compared with those from previous work. The results obtained in this paper can provide important information on the explanation of geochemical depth limit for natural gas and on the exploration of gas reservoirs. | YUE Changtao LI Shuyuan DING Kangle ZHONG Ningning | 2005 | Science China Earth Sciences2005，48，8： | 8 |
| 6 | Chemical kinetics study of hydrocarbon regeneration from organic matter in carbonate source rocks and its significance显示文摘In the comparison research of hydrocarbon regeneration, a low maturity carbonate source rock is heated to different temperatures in a gold tube to obtain a series of samples with different maturities. Then, the heated samples, before and after extraction, are subjected to Rock-Eval pyrolysis through a thermal simulation of hydrocarbon regeneration in order to inspect pyrolysis characteristics and probe into the characteristics of the chemical kinetics of each sample. The results indicate that, whether hy- drocarbon regeneration peak is delayed or advanced, the potential of hydrocarbon regeneration is closely related to the expulsion amount and breakdown maturity of primary hydrocarbon generation. After extraction, the average activation energy of artificially maturated samples increases with the in- creasing maturity, but the chemical kinetic properties of un-extracted samples decrease. The calibrated chemical kinetic models that describe extracted and un-extracted samples are applied to the Bohai Bay and the Songliao Basin, and the results indicate that the combination of the two models can explain some contradictory conclusions previously reported. These results also facilitate the quantitative evaluation of the amount of hydrocarbon regeneration by the chemical kinetic method. | LU ShuangFang ZHONG NingNing XUE HaiTao PAN ChangChun LI JiJun LI HongTao | 2007 | Science China Earth Sciences2007，50，4： | 8 |
| 7 | Definition and sturcture characteristics of pores in mylonitized organic-rich shales显示文摘Gas shales with a high gas content were drilled in the Lower Cambrian Lujiaping Formation in the northeastern Sichuan Basin,close to the Chengkou Fault in the Dabashan arc-like thrust fold belt.The equivalent vitrinite reflectance values of organic matters are over 4.0%Ro.The pore structures of the shales were investigated based on microscopy,field emission scanning electron microscopy(FESEM)observations,and low temperature N2 adsorption analysis.The study suggests that cleavages,comprising clay minerals mixed up with organic matter and other insoluble residues,were developed in the rock layers.The clay minerals are directionally arranged,displaying a mylonitized texture.Abundant nanometer-size organic matter and clay mineral particles are well mixed in the cleavage domains,which developed the mylonitized pore system that consists of nanometer-size intergranular pore spaces,aggregate pore spaces in clay mineral flakes and pore network.This mylonitized pore system has high specific surface area,high methane adsorption capacity,and high capillary pressure,which collectively contributes to the preservation of shale gas in such a complex tectonic area.The discovery of the mylonitized pore structure in organic-rich shales may reveal a new mechanism of shale gas enrichment in complex tectonic areas with over-mature organic matter in the northeastern part of Sichuan Basin. | MA Yong ZHONG NingNing HAN Hui LI DaHua ZHANG Yi CHENG LiJun | 2014 | Science China Earth Sciences2014，57，12： | 5 |
| 8 | Simulation experiments on the reaction system of CH_4-MgSO_4-H_2O显示文摘H2S-rich gas in carbonate reservoirs is usually attributed to thermochemical sulfate reduction (TSR). In this paper, thermal simulation experiments on the reaction system of CH4-MgSO4-H2O were carried out using autoclave at 425℃―525℃. The threshold temperature for initiating TSR is much lower than our previous studies (550 ℃ ). Properties of the reaction products were analyzed by microcoulometry, gas-chromatography (GC), Fourier transform-infrared spectrometry (FT-IR) and X-ray diffraction (XRD) methods. Thermodynamics and reaction kinetics of TSR processes were investigated on the basis of the experimental data. The results show that thermochemical reduction of magnesium sulfate with methane can proceed spontaneously to produce magnesium oxide, hydrogen sulfur, and carbon diox-ide as the main products, and high temperature is thermodynamically favorable to the reaction. Ac-cording to the reaction model, the calculated activation energy of TSR is 101.894 kJ/mol, which is lower than that by most previous studies. Mg2+ may have played a role of catalytic action in the process of TSR. The elementary steps of TSR and reaction mechanism were discussed tentatively. The study can provide important information on the explanation of geochemical depth limit for natural gas and on the generation of high H2S gas in deep carbonates reservoirs. | DING KangLe LI ShuYuan YUE ChangTao ZHONG NingNing | 2008 | Chinese Science Bulletin2008，53，7： | 3 |
| 9 | A GC×GC-ToFMS Investigation of the Unresolved Complex Mixture and Associated Biomarkers in Biodegraded Petroleum显示文摘Heavy biodegraded crude oils have larger numbers of coeluting compounds than nonbiodegraded oils, and they are typically not resolved with conventional gas chromatography(GC). This unresolved complex mixture(UCM) has been investigated using comprehensive two-dimensional gas chromatography–time-of-flight mass spectrometry(GC×GC-To FMS) within a set of biodegraded petroleums derived from distinct sedimentary basins, including northwestern Sichuan(Neoproterozoic, marine), Tarim(Early Paleozoic, marine), Bohai Bay(Eocene, saline/brackish) and Pearl River Mouth(Eocene, freshwater). In general, the hydrocarbons that constitute the UCM in petroleum saturate fractions can be classified into three catalogues based on the distributions of resolved compounds on two dimensional chromatograms. Group 1 is composed mainly of normal and branched alkanes, isoprenoid alkanes and monocyclic alkanes; Group 2 comprises primarily terpanes ranging from two to five rings, and Group 3 is dominated by monoaromatic hydrocarbons such as tetralins and monoaromatic steranes. In addition, the UCM is source dependent and varies between oil populations. i.e., the UCM of petroleum derived from Precambrian and Early Paleozoic marine, Eocene saline/brackish and freshwater source rocks is specifically rich in higher homologues of A-norsteranes, series of 1,1,3-trimethyl-2-alkylcyclohexanes(carotenoid-derived alkanes), and tetralin and indane compounds, respectively. | WANG Guangli Bernd Rolf Tatsuo SIMONEIT SHI Shengbao WANG Tieguan ZHONG Ningning WANG Peirong | 2018 | Acta Geologica Sinica(English Edition)2018，92，5： | 3 |
| 10 | Pore Characteristics and Factors Controlling Lacustrine Shales from the Upper Cretaceous Qingshankou Formation of the Songliao Basin,Northeast China:A Study Combining SEM,Low-temperature Gas Adsorption and MICP Experiments显示文摘To investigate pore characteristics and the factors controlling lacustrine shales,geochemical,mineralogical and petrophysical experiments were performed on 23 shale samples from the Qingshankou Formation of the Songliao Basin,China.A comparison of mercury injection capillary pressure(MICP)and low-temperature N2 adsorption pore-size distribution showed that MICP has a higher pore-size distribution(PSD)line in its overlapping pore diameter range,which may be elevated by the higher pressure of MICP.Therefore,in the overlapping range,low-temperature N2 adsorption data were preferred in pore characterization.Negative correlations were observed between pore volumes and TOC content,indicating organic matter pores are not well-developed in the studied samples.This may be related to their low grade of maturity and type I kerogens.There existed negative relationships between pore volumes and S1,which illustrated that liquid hydrocarbons occupied some pore space.Micropore volume had a better correlation with S1 than mesopore and macropore volumes,which suggests that liquid hydrocarbons preferentially occur in micropores.No obvious relationships between pore volumes and quartz or feldspar were observed,while pore volumes increased with the increasing clay mineral content.These relationships indicate that intraparticle pores in clay minerals represent the principal pore type. | HAN Hui DAI Jie GUO Chen ZHONG Ningning PANG Peng DING Zhengang CHEN Jianping HUANG Zhenkai GAO Yuan LUO Jinyu LI Qirui ZHANG Zhaokun | 2021 | Acta Geologica Sinica(English Edition)2021，95，2： | 2 |
| 11 | Discovery of cutinitic liptobiolith in northwestern China and a comparative study with Luquan Devonian coal显示文摘Devonian cutinitic liptobiolith is a special cuticle-rich coal formed during the early stage of land plant evolution. In China, this special coal has previously only been reported in the Yangtze area, with the Luquan Devonian cutinitic liptobiolith of Yunnan Province being the most well-known. Recently, this type of coal was first discovered in the Bulonggoer Sag, to the northwest of the Junggar Basin, NW Xinjiang. Its geological age is regarded as the Givetian period of the late Middle Devonian,which is equivalent to the age of the Luquan Devonian coal. The cutinitic liptobiolith from NW Xinjiang has a distinct sheet-like texture resembling a stack of paper or leaf sheets in appearance, and so it is commonly called 'paper coal' or 'leaf coal'. Ribbonlike cutinite(thick-walled type) is the most abundant maceral in the coal(>60% and up to 80%, on a mineral-free basis), followed by ribbon-like collotelinite. The NW Xinjiang and Luquan cutinitic liptobioliths share similar maceral compositions;while their coal-forming plants and depositional conditions are distinct. The NW Xinjiang cutinitic liptobiolith was deposited in a regional fluvial or flood plain condition, with lycopsids as the dominant coal-forming plants. In contrast, the Luquan cutinitic liptobiolith formed in a coastal-lagoon environment, with primitive ferns as the predominant coal-forming plants, followed by lycopsids. The saturated fractions of the NW Xinjiang and Luquan liptobioliths are mainly composed of tetracyclic diterpanes. However, the tetracyclic diterpane compositions in the NW Xinjiang cutinitic liptobiolith are distinct from those in the Luquan Devonian coal:The former is dominated by atisanes and the latter is mainly composed of phyllocladanes. Different coal-forming plants may have contributed to the distinct tetracyclic diterpane compositions. | Daofu SONG Tieguan WANG Ningning ZHONG Yuan CHEN Dengfa HE Di LI | 2021 | Science China Earth Sciences2021，64，4： | 2 |
| 12 | Combination and superimposition of source kitchens and their effects on hydrocarbon accumulation in the hinterland of the Junggar Basin,west China显示文摘In the hinterland of the Junggar Basin,there are multiple depressions with multiple sets of source rocks. Therefore,the conditions of hydrocarbon sources are complex,and the geochemical characteristics and sources of hydrocarbon vary in different structural belts. The evolution of the Che-Mo palaeohigh affected the formation of hydrocarbon source kitchens and hydrocarbon migration. We studied the combination and superimposition of hydrocarbon source kitchens,using as an example the hinterland of the Junggar Basin(including the Yongjin,Zhengshacun,Moxizhuang and Luliang uplift areas) . The study was based on geochemical analyses of crude oil and fluid inclusions,and the histories of tectonic evolution and hydrocarbon generation. The results indicated that before the Paleogene there were two hydrocarbon-generating depressions:the Western Well Pen1 depression and the Changji depression on the south and north sides of the Che-Mo palaeohigh,respectively. The Permian source kitchen had been generating hydrocarbon continuously since Triassic and reached high maturity stage in the Cretaceous period. After Paleogene,the adjustment of the Che-Mo palaeohigh led to the subsidence of the Changji depression and the Jurassic source rocks reached mature stage and became the main source kitchens. However,the Jurassic source rocks in the Western Well Pen1 depression were still in a low maturity stage and did not generate oil because of the adjustment of tectonic movements. As a result,in the central and southern parts of the Junggar Basin,Jurassic source rocks generated oil,but in the Luliang uplift,the crude oil was from the Permian source rocks in the Western Well Pen1 depression and the Jurassic source rocks did not contribute. The crude oil in the central Zhengshacun-Moxizhuang belt was from the Permian source rocks in two depressions,and partially from the Jurassic source rocks. The crude oil in the Luliang uplift was from the source rocks of the lower Permian Fengcheng Formation and middle Permian Wuerhe Formation,which is characterized by superimposition of two sets of source kitchens and three accumulation stages. The crude oil in the Yongjin tectonic belt was from the lower Permian,middle Permian and Jurassic source rocks,which is characterized by superimposition of three sets of source kitchens and two accumulation stages. The crude oil in the Zhengshacun tectonic belt was from a combination of source kitchens of lower Permian and middle Permian in the Western Well Pen1 depression in the early stage and from the superimposition of Jurassic source rocks in the Changji depression in the late stage. | Zhang Zhihuan Qin Liming Qiu Nansheng Zhong Ningning Zhang Zhenying Li Wei | 2010 | Petroleum Science2010，7，1： | 2 |

| 18 | A precipitate-free AlCoFeNi eutectic high-entropy alloy with strong strain hardening显示文摘Over recent years,eutectic high-entropy alloys(EHEAs)have intrigued substantial research enthusiasms due to their good castability as well as balanced strength-ductility synergy.In this study,a bulk cast Al_(19.25)Co_(18.86)Fe_(18.36)Ni_(43.53)EHEA is developed with fine in-situ lamellar eutectics.The eutectics comprise alternating ordered face-centered-cubic(L1_(2))and ordered body-centered-cubic(B2)phases with semicoherent interfaces.The resulting microstructure resembles that of most reported as-cast EHEAs,but the B2 lamellae are devoid of nano-precipitates because of the Cr-element removal in current tailored eutectic composition.Surprisingly,the B2 lamellae still feature much higher deformation resistance than the L1_(2) lamellae,so that less lattice defects are detected in the B2 lamellae until the fracture.More interestingly,in the L1_(2) lamellae we identify a dynamic microstructure refinement that correlates to extraordinary strain hardening in tension.The precipitate-free EHEA consequently shows excellent tensile ductility of~10%and high ultimate strength up to~956 MPa. | Peijian Shi Yi Li Yuebo Wen Yiqi Li Yan Wang Weili Ren Tianxiang Zheng Yifeng Guo Long Hou Zhe Shen Ying Jiang Jianchao Peng Pengfei Hu Ningning Liang Qingdong Liu Peter K.Liaw Yunbo Zhong | 2021 | Journal of Materials Science & Technology2021，，30： | 1 |
| 19 | Replication,pathogenicity,and transmission of SARS-CoV-2 in minks显示文摘Minks are raised in many countries and have transmitted severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)to humans.However,the biologic properties of SARS-CoV-2 in minks are largely unknown.Here,we investigated and found that SARS-CoV-2 replicates efficiently in both the upper and lower respiratory tracts,and transmits efficiently in minks via respiratory droplets;pulmonary lesions caused by SARS-CoV-2 in minks are similar to those seen in humans with COVID-19.We further found that a spike protein-based subunit vaccine largely prevented SARS-CoV-2 replication and lung damage caused by SARS-CoV-2 infection in minks.Our study indicates that minks are a useful animal model for evaluating the efficacy of drugs or vaccines against COVID-19 and that vaccination is a potential strategy to prevent minks from transmitting SARS-CoV-2. | Lei Shuai Gongxun Zhong Quan Yuan Zhiyuan Wen Chong Wang Xijun He Renqiang Liu Jinliang Wang Qinjian Zhao Yuxiu Liu Ningning Huo Junhua Deng Jingjing Bai Hongchao Wu Yuntao Guan Jianzhong Shi Kegong Tian Ningshao Xia Hualan Chen Zhigao Bu | 2021 | National Science Review2021，8，3： | 1 |
