| 1 | The abnormal distribution of the molecular fossils in the pre-Cambrian and Cambrian:its biological significance显示文摘Dinosteranes and 4-methyl-24-ethylcholestanes are usually to be thought of as biomarkers for dinoflagellates, and 24-norcholestanes and C28 steranes for diatom. Therefore, the highest concentrations of these compounds are typically found in strata deposited since the beginning of the Mesozoic. However these compounds appeared widely and abundantly in extracts from organic-rich sediments in the Sinian and Cambrian of the Tarim Basin. This suggests that some of the planktonic algae such as dinoflagellates and diatoms have an earlier origin than the Mesozoic. Some of the remarkable algal fossils observed in the Cambrian, in both well He 4 and the outcrop section of Xiao-Er-Bulak, Tarim Basin, provide possible biological evidence for this kind of inference. | 张水昌 J.Michael Moldowan Maowen Li 边立曾 张保民 王飞宇 何忠华 王大锐 | 2002 | Science China Earth Sciences2002，45，3： | 35 |
| 2 | 分子化石在寒武—前寒武纪地层中的异常分布及其生物学意义显示文摘甲藻甾烷、4-甲基甾烷、24-降胆甾烷及C28甾烷等常被作为沟鞭藻和硅藻的生 物标志,所以它们在中生代以来的地层中常常具有很高的浓度.然而,这些公认具有特 殊结构和局限生源的化合物却在塔里木盆地寒武系和震旦系含较高有机质丰度的岩石 抽提物中普遍存在,且具有异常高的浓度.这种结果意味着某些浮游藻如沟鞭藻和硅 藻可能具有更古老的前驱种属,在塔里木盆地和4井及肖尔布拉克剖面寒武系地层中 观察到的一些异常的藻化石,为这种推测提供了可能的生物学证据. | 张水昌 J.M.Moldowan Maowen Li 边立曾 张宝民 王飞宇 何忠华 王大锐 | 2001 | 中国科学(D辑)2001，31，4： | 39 |
| 3 | Molecular fossils and oil-source rock correlations in Tarim Basin, NW China显示文摘The distribution of 'molecular fossils' (bio-markers) of steroid compounds in extracts from some spe-cific geologic age in the Tarim Basin have been analyzed andare used as the fingerprints for the oil-source rock correla-tion. Having been affected by maturation, migration, phasefractionation and biodegradation, not any molecular fossilsrelated to source and environment can be used as the finger-prints for oil-source rock correlation. Some special bio-markers widely existed in the extracts from Cambrian andOrdovician rocks in the Tarim Basin and showed obviousdifference in each stratum, including dinosteranes (C30),4-methyl-24-ethyl-cholestanes (C30) and their aromatizedsteroids, C24-norcholestanes and C28 steranes originated fromdinoflagellates and diatom. Few oils such as the heavy oildrilled in the Cambrian reservoir from Tadong 2 well (TD2)correlated well with the extracts from the Cambrian. Theamazing similarity of the relative contents of these com-pounds between the marine oils produced in Tazhong andTabei uplifts and the extracts from the Upper Ordoviciansuggests that the Middle-Upper Ordovician is the very likelymain source for the marine oils. | ZHANG Shuichang LIANG Digang LI Maowen XIAO Zhongyao HE Zhonghua | 2002 | Chinese Science Bulletin2002，47，S1： | 25 |
| 4 | 川东北高含硫化氢气藏中储层沥青的特征显示文摘川东北普光气田和毛坝气田高含硫化氢气藏中储层沥青显微镜下光学特征、沥青反射率值及S/C原子比均具有明显的非均质性,这说明在由古油藏原油高温热裂解形成现今气藏的过程中硫酸盐热化学还原(TSR)反应不充分。同时,飞仙关组和长兴组气藏中硫化氢相对含量与烃类气体组分及碳同位素之间没有明显的相关性,进一步说明TSR反应还没有明显波及到烃类气体。这一研究结果表明这些气藏中烃类气体组分及碳同位素没有受到TSR反应的明显影响,因而能够基本反映母源性质和演化程度,在天然气成因分析及气源对比研究时可能不需要经过人们以往所建议的大幅度校正,这对于该地区天然气藏的成因与成藏机制解剖具有重要的指导意义。 | 胡安平 LI Maowen 杨春 戴金星 马永生 郭彤楼 | 2010 | 石油学报2010，31，2： | 16 |
| 5 | Buoyance-driven hydrocarbon accumulation depth and its implication for unconventional resource prediction显示文摘The discovery of unconventional hydrocarbon resources since the late 20th century changed geologists’understanding of hydrocarbon migration and accumulations and provides a solution to energy shortage.In 2016,unconventional oil production in the USA accounted for 41%of the total oil production;and unconventional natural gas production in China accounted for 35%of total gas production,showing strong growth momentum of unconventional hydrocarbons explorations.Unconventional hydrocarbons generally coexist with conventional petroleum resources;they sometimes distribute in a separate system,not coexisting with a conventional system.Identification and prediction of unconventional resources and their potentials are prominent challenges for geologists.This study analyzed the results of 12,237 drilling wells in six representative petroliferous basins in China and studied the correlations and differences between conventional and unconventional hydrocarbons by comparing their geological features.Migration and accumulation of conventional hydrocarbon are caused dominantly by buoyance.Wepropose a concept of buoyance-driven hydrocarbon accumulation depth to describe the deepest hydrocarbon accumulation depth driven dominantly by buoyance;beyond this depth the buoyance becomes unimportant for hydrocarbon accumulation.We found that the buoyance-driven hydrocarbon accumulation depth in petroliferous basins controls the different oil/gas reservoirs distribution and resource potentials.Hydrocarbon migration and accumulations above this depth is dominated by buoyancy,forming conventional reservoirs in traps with high porosity and permeability,while hydrocarbon migration and accumulation below this depth is dominated by non-buoyancy forces(mainly refers to capillary force,hydrocarbon volumeexpansion force,etc.),forming unconventional reservoirs in tight layers.The buoyance-driven hydrocarbon accumulation depths in six basins in China range from 1200mto 4200 m,which become shallowerwith increasing geothermal gradient,decreasing particle size of sandstone reservoir layers,or an uplift in the whole petroliferous basin.The predicted unconventional resource potential belowthe buoyance-driven hydrocarbon accumulation depth in six basins in China is more than 15.71×10^(9) t oil equivalent,among them 4.71×10^(9) t reserves have been proved.Worldwide,94%of 52,926 oil and gas reservoirs in 1186 basins are conventional reservoirs and only 6%of them are unconventional reservoirs.These 94%conventional reservoirs show promising exploration prospects in the deep area below buoyance-driven hydrocarbon accumulation depth. | Xiongqi Pang Chengzao Jia Wenyang Wang Zhangxin Chen Maowen Li Fujie Jiang Tao Hu Ke Wang Yingxun Wang | 2021 | Geoscience Frontiers2021，12，4： | 9 |
| 6 | A unified model for the formation and distribution of both conventional and unconventional hydrocarbon reservoirs显示文摘The discovery and large-scale exploration of unconventional oil/gas resources since 1980s have been considered as the most important advancement in the history of petroleum geology;that has not only changed the balance of supply and demand in the global energy market,but also improved our understanding of the formation mechanisms and distribution characteristics of oil/gas reservoirs.However,what is the difference of conventional and unconventional resources and why they always related to each other in petroliferous basins is not clear.As the differences and correlations between unconventional and conventional resources are complex challenging issues and very critical for resources assessment and hydrocarbon exploration,this paper focused on studying the relationship of formations and distributions among different oil/gas reservoirs.Drilling results of 12,237 exploratory wells in 6 representative petroliferous basins of China and distribution characteristics for 52,926 oil/gas accumulations over the world were applied to clarify the formation conditions and genetic relations of different oil/gas reservoirs in a petroliferous basin,and then to establish a unified model to address the differences and correlations of conventional and unconventional reservoirs.In this model,conventional reservoirs formed in free hydrocarbon dynamic field with high porosity and permeability located above the boundary of hydrocarbon buoyancy-driven accumulation depth limit.Unconventional tight reservoirs formed in confined hydrocarbon dynamic field with low porosity and permeability located between hydrocarbon buoyancy-driven accumulation depth limit and hydrocarbon accumulation depth limit.Shale oil/gas reservoirs formed in the bound hydrocarbon dynamic field with low porosity and ultra-low permeability within the source rock layers.More than 75%of proved reserves around the world are discovered in the free hydrocarbon dynamic field,which is estimated to contain only 10%of originally generated hydrocarbons.Most of undiscovered resources distributed in the confined hydrocarbon dynamic field and the bound hydrocarbon dynamic field,which contains 90%of original generated hydrocarbons,implying a reasonable and promising area for future hydrocarbon explorations.The buried depths of hydrocarbon dynamic fields become shallow with the increase of heat flow,and the remaining oil/gas resources mainly exist in the deep area of“cold basin”with low geothermal gradient.Lithology changing in the hydrocarbon dynamic field causes local anomalies in the oil/gas dynamic mechanism,leading to the local formation of unconventional hydrocarbon reservoirs in the free hydrocarbon dynamic field or the occurrence of oil/gas enrichment sweet points with high porosity and permeability in the confined hydrocarbon dynamic field.The tectonic movements destroy the medium conditions and oil/gas components,which leads to the transformation of conventional oil/gas reservoirs formed in free hydrocarbon dynamic field to unconventional ones or unconventional ones formed in confined and bound hydrocarbon dynamic fields to conventional ones. | Xiongqi Pang Chengzao Jia Junqing Chen Maowen Li Wenyang Wang Qinhong Hu Yingchun Guo Zhangxin Chen Junwen Peng Keyu Liu Keliu Wu | 2021 | Geoscience Frontiers2021，12，2： | 8 |
| 7 | Interfacial engineering of Ni/V2O3 for hydrogen evolution reaction显示文摘Electrocatalytic water splitting offers a sustainable route for hydrogen production,enabling the clean and renewable alternative energy system of hydrogen economy.The scarcity and high-cost of platinum-group-metal(PGM)materials urge the exploration of high-performance non-PGM electrocatalysts.Herein,a unique hierarchical structure of NiA/2O3 with extraordinary electrocatalytic performance(e.g.t overpotentials as low as 22 mV at 20 mA·cm^-2 and 94 mV at 100 mA·cm^-2)toward hydrogen evolution reaction in alkaline electrolyte(1 M KOH)is reported.The investigation on the hierarchical NiA/2O3 with a bimodal size-distribution also offers insight of interfacial engineering that only proper NiA/2O3 interface can effectively improve H20 adsorption,H20 dissociation as well as H adsorption,for an efficient hydrogen production. | Yang Chen Yuan Rao Rongzhi Wang Yanan Yu Qiulin Li Shujuan Bao Maowen Xu Qin Yue Yanning Zhang Yijin Kang | 2020 | Nano Research2020，13，9： | 3 |
| 8 | Serial Interval and Reproductive Number of COVID-19 Among 116 Infector-infectee Pairs—Jingzhou City,Hubei Province,China,2020显示文摘What is already known about this topic?The key epidemiological parameters including serial interval,basic reproductive number(R0),and effective reproductive number(Rt)are crucial for coronavirus disease 2019(COVID-19)control and prevention.Previous studies provided different estimations but were often flawed by some limitations such as insufficient sample size and selection bias.What is added by this report?In this study,a total of 116 infector-infectee pairs meeting strict inclusion criteria were selected for analysis.The mean serial interval of COVID-19 was 5.81 days(standard deviation:3.24).The estimated mean with 95%confidence interval of R0 was 3.39(3.07–3.75)and 2.98(2.62–3.38)using exponential growth(EG)and maximum likelihood(ML)methods,respectively.The Rt in the early phase of the epidemic was above 1 with the peak of 4.43 occurring on January 8,and then showing subsequent declines and approaching 1 on January 24.What are the implications for public health practices?This study supports previous findings that COVID-19 has high transmissibility and that implementing comprehensive measures is effective in controlling the COVID-19 outbreak. | Tian Liu Li Qi Menglei Yao Keqing Tian Maowen Lin Hong Jiang Minmin Zeng Jigui Huang | 2020 | China CDC weekly2020，2，27： | 2 |

| 10 | Curtailing Carbon Usage with Addition of Functionalized NiFe2O4 Quantum Dots:Toward More Practical S Cathodes for Li-S Cells显示文摘Smartcombination of manifold carbonaceous materials with admirable functionalities(like full of pores/functional groups,high specific surface area) is still a mainstream/preferential way to address knotty issues of polysulfides dissolution/shuttling and poor electrical conductivity for S-based cathodes.However,extensive use of conductive carbon fillers in cell designs/technology would induce electrolytic overconsumption and thereby shelve high-energy-density promise of Li-S cells.To cut down carbon usage,we propose the incorporation of multi-functionalized NiFe2O4 quantum dots(QDs) as affordable additive substitutes.The total carbon content can be greatly curtailed from 26%(in traditional S/C cathodes) to a low/commercial mass ratio(~5%).Particularly,note that NiFe2O4 QDs additives own superb chemisorption interactions with soluble Li2Sn molecules and proper catalytic features facilitating polysulfide phase conversions and can also strengthen charge-transfer capability/redox kinetics of overall cathode systems.Benefiting from these intrinsic properties,such hybrid cathodes demonstrate prominent rate behaviors(decent capacity retention with ~526 mAh g^-1 even at 5 A g^-1) and stable cyclic performance in LiNO3-free electrolytes(only ~0.08% capacity decay per cycle in 500 cycles at 0.2 A g^-1).This work may arouse tremendous research interest in seeking other alternative QDs and offer an economical/more applicable methodology to construct low-carbon-content electrodes for practical usage. | Ning Li Ting Meng Lai Ma Han Zhang JiaJia Yao Maowen Xu Chang Ming Li Jian Jiang | 2020 | Nano-Micro Letters2020，12，11： | 2 |
| 11 | Diagnosis of coronary artery disease using targeted post-mortem computed tomography coronary angiography:a case report显示文摘Targeted post-mortem computed tomography(PMCT)combined with coronary angiography has the potential to play a significant role in the investigation of sudden cardiac death.The authors utilized a targeted PMCT coronary angiography in a case involving a 53-year-old man who died from acute myocardial ischemia and cardiac decompensation which may result from coronary artery disease(CAD).The victim collapsed suddenly at work and died soon after arrival to hospital.The body was examined using PMCT and targeted PMCT coronary angiography.The left anterior descending coronary artery exhibited 75%-100%stenosis in the middle segment;however,the distal segment could not be clearly visualized.In addition,the left circumflex and right coronary artery exhibited calcification,atherosclerosis and an area of 50% stenosis.Signs of cardiogenic pulmonary oedema were also identified.The imaging results suggested that this individual had coronary atherosclerosis and probably died from CAD.The autopsy and histological examination revealed acute myocardial ischemia and myocardial scarring,confirming the cause of death while excluding other probabilities.In summary,targeted post-mortem computed tomography angiography(PMCTA)can visualize the arteries and estimate the degree of principal pathological changes.This method is a simple,reliable and sensitive technique for identifying the presence of coronary atherosclerosis.It is a valuable post-mortem forensic imaging method and should be recommended in the investigation of suspicious cardiac deaths. | Lei Wan Yu Shao Donghua Zou Ping Huang Zhengdong Li Maowen Wang Yijiu Chen | 2017 | Forensic Sciences Research2017，2，2： | 2 |
| 12 | Enzymatically-degradable hydrogel coatings on titanium for bacterial infection inhibition and enhanced soft tissue compatibility via a self-adaptive strategy显示文摘Ideal percutaneous titanium implants request both antibacterial ability and soft tissue compatibility.ZnO structure constructed on titanium has been widely proved to be helpful to combat pathogen contamination,but the biosafety of ZnO is always questioned.How to maintain the remarkable antibacterial ability of ZnO and efficiently reduce the corresponding toxicity is still challenging.Herein,a hybrid hydrogel coating was constructed on the fabricated ZnO structure of titanium,and the coating was proved to be enzymatically-degradable when bacteria exist.Then the antibacterial activity of ZnO was presented.When under the normal condition(no bacteria),the hydrogel coating was stable and tightly adhered to titanium.The toxicity of ZnO was reduced,and the viability of fibroblasts was largely improved.More importantly,the hydrogel coating provided a good buffer zone for cell ingrowth and soft tissue integration.The curbed Zn ion release was also proved to be useful to regulate fibroblast responses such as the expression of CTGF and COL-I.These results were also validated by in vivo studies.Therefore,this study proposed a valid self-adaptive strategy for ZnO improvement.Under different conditions,the sample could present different functions,and both the antibacterial ability and soft tissue compatibility were finely preserved. | Jin Leng Ye He Zhang Yuan Bailong Tao Ke Li Chuanchuan Lin Kun Xu Maowen Chen Liangliang Dai Xuemin Li Tony Jun Huang Kaiyong Cai | 2021 | Bioactive Materials2021，6，12： | 2 |
