| 1 | Facile Synthesis and Application of Ag-Chemically Converted Graphene Nanocomposite显示文摘An in situ chemical synthesis approach has been employed to prepare an Ag-chemically converted graphene (CCG) nanocomposite. The reduction of graphene oxide sheets was accompanied by generation of Ag nanoparticles. The structure and composition of the nanocomposites were confirmed by means of transmission electron microscopy (TEM), atomic force microscopy (AFM) and X-ray diffraction. TEM and AFM results suggest a homogeneous distribution of Ag nanoparticles (5-10 nm in size) on CCG sheets. The intensities of the Raman signals of CCG in such nanocomposites are greatly increased by the attached silver nanoparticles, i.e., there is surface-enhanced Raman scattering activity. In addition, it was found that the antibacterial activity of free Ag nanoparticles is retained in the nanocomposites, which suggests they can be used as graphene-based biomaterials. | Jianfeng Shen Min Shi Na Li Bo Yan Hongwei Ma Yizhe Hu Mingxin Ye | 2010 | Nano Research2010，3，5： | 29 |

| 4 | New Approaches and Markers for Identifying Secondary Biogenic Coalbed Gas显示文摘According to the adsorption-desorption characteristics of coalbed gas and analysis of various experimental data,this paper proposes that the generation of secondary biogenic gas(SBG) and its mixing of with the residual thermogenic gas at an early stage inevitably lead to secondary changes of the thermogenic gas and various geochemical additive effects.Experimental results also show that the fractionation of the carbon isotope of methane of coal core desorption gas changes very little;the δ13C1 value of the mixed gas of biogenic and thermogenic gases is between the δ13C1 values of the two 'original' gases,and the value is determined by the carbon isotopic compositions and mixing proportions of the two 'original' methanes.Therefore this paper proposes that the study on the secondary changes of the thermogenic gas and various additive effects is a new effective way to study and identify SBG.Herein,a systematic example of research on the coalbed gas(Huainan coalbed gas) is further conducted,revealing a series of secondary changes and additive effects,the main characteristics and markers of which are:(1) the contents of CO2 and heavy-hydrocarbons decrease significantly;(2) the content of CH4 increases and the gas becomes drier;(3) the δ13C and δD values of methane decrease significantly and tend to have biogenetic characteristics;and(4) the values of δ13C2 and δ13CCO2 grow higher.These isotopic values also change with the degradation degrees by microbes and mixing proportions of the two kinds of gases in different locations.There exists a negative correlation between the δ13C1 vs δ13CCO2 values.The △δ13CC2-C1 values obviously become higher.The distributions of the △δ13CCO2-C1 values are within certain limits and show regularity.There exist a positive correlation between the N2 versus Ar contents,and a negative correlation between the N2 versus CH4 contents,indicating the down forward infiltration of the surface water containing air.These are important markers of the generation and existence of SBG. | TAO Mingxin LI Jing LI Xiaobin MA Yuzhen LI Zhongping WANG Zuodong GAO Zhongliang ZHANG Xiaojun WANG Yanlong | 2012 | Acta Geologica Sinica(English Edition)2012，86，1： | 4 |

| 6 | Effect of calcinations temperature on the luminescence intensity and fluorescent lifetime of Tb^(3+)-doped hydroxyapatite(Tb-HA)nanocrystallines显示文摘Hydroxyapatite luminescent nanocrystallines doped with 6 mol.%Tb^(3+)(Tb-HA)were prepared via chemical deposition method and calcined at different temperature,and the effects of calcinations temperature on the luminescence intensity and fluorescent lifetime were studied.TEM image of Tb-HA revealed that the shape of nanocrystallines changed from needle-like to short rod-like and sphere-like with the increase of calcinations temperature;while the particles sizes decreased from 190 nm to 110 nm.the crystallinity degree increased.the typical emission peaks attributed to Tb^(3+) ions were observed in emission spectra of 6 mol.%Tb-HA under 378 nm excitation.the luminescent intensity of Tb-HA,which showed the fluorescence quenching,firstly enhanced and then decreased at 700℃;while the fluorescent lifetime increased firstly and then decreased after 600℃.Furthermore,the ratio of intensity between 545 nm and 490 nm corresponding to electric-dipole and magnetic-dipole transition(I_(R):I_(O))increases firstly and then decreases,which revealed that the proportion of substitute type and site of Ca^(2+) ions by Tb^(3+) ions were helpful to realize the substitute process and functional structure design. | Hairong Yin Yanxiao Li Jianguang Bai Mingxin Ma Jing Liu | 2017 | Journal of Materiomics2017，3，2： | 2 |

| 8 | Comprehensive study on genetic pathways and parent materials of secondary biogenic gas in coalbeds显示文摘The types of substances in coal rock used by microbes,the specific ways in which microbes produce secondary biogenic gas(SBG)and whether substances exist in the coal seam for the formation of a large amount of SBG are important basic scientific issues.This paper conducts a systematic and comprehensive research study on the above issues using methods such as the isotopic tracing of gas,the analysis of coal organic geochemistry,and gas-producing simulation experiments of coal.Results show that the formation of SBG is by the microbial reduction of CO2and the SBG-producing coal seam undergoes microbial degradation.The thermogenic heavy gaseous hydrocarbons have also been degraded by microorganisms and possibly transformed into microbialoriginated CO2.A large amount of CO2,a relatively large amount of H2and a certain amount of heavy gaseous hydrocarbons may form in the thermal evolution of coal.These substances and the microbial-originated CO2and coal seam water can finally become parent materials of SBG.These components are rich in coal seams of medium–low thermal evolution,which should be the main coal seams for SBG formation and exploration. | Mingxin Tao Wanchun Wang Zhongping Li Yuzhen Ma Jing Li Xiaobin Li | 2014 | Chinese Science Bulletin2014，59，10： | 2 |

| 11 | CeO_(2)C_(2)Nanoparticles with Oxygen-Enriched Vacancies In-site Self-embedded in Fe,N Co-doped Carbon Nanofibers as Efficient Oxygen Reduction Catalyst for Zn-Air Battery显示文摘Rational design of robust non-noble electrocatalysts with numerous oxygen vacancies and highly reactive activity for oxygen reduction reaction(ORR)towards Zn-air batteries is extremely paramount yet challenging.Herein,a novel CeO_(2)C_(2)nanoparticles self-embedded in Fe,N co-doped carbon nanofibers(CeO_(2)C_(2)@Fe-N-C)heterostructure catalyst has been prepared by the in-site dual template assisted electrospinning technique and subsequent high temperature pyrolysis strategy.Thanks to the CeO_(2)C_(2)with oxygen-enriched vacancies and versatile Fe-N-C with rich reactive species and high conductivity,CeO_(2)C_(2)@Fe-N-C catalyst exhibits outstanding catalytic performance in the ORR process,and shows excellent methanol tolerance and cycle stability.In addition,CeO_(2)C_(2)@Fe-N-C delivers a nearly four-electron transfer process in the process of oxygen reduction catalysis,providing a fast-electrochemical kinetic rate,which makes it an efficient air cathode for the Zn-air battery.Importantly,the Zn-air battery fabricated with CeO_(2)C_(2)@Fe-N-C cathode achieves superior performance including large open-circuit voltage(1.5 V)and high specific capacity(780 mAh·g–1 at 10 mA·cm–2)together with superior reversibility and cycling stability,outperforming commercial Pt/C catalyst.The present work introduces a new strategy to design and develop highly active non-noble catalysts and highlights the synergy from heterostructure in oxygen electrocatalysis for advanced Zn-air batteries. | Mingxin Zhang Hui Peng Kanjun Sun Xuan Xie Xiaofei Lei Sitong Liu Guofu Ma Ziqiang Lei | 2022 | Chinese Journal of Chemistry2022，40，23： | 1 |

| 14 | Regional characteristics of the lithospheric structure in the southeast of North China revealed by explosion seismology显示文摘Based on the blasting seismic detection data obtained in the southeast of North China in recent years,this paper comprehensively analyzes and studies the crust-mantle lithospheric structure and seismological characteristics of different tectonic regions,such as offshore basins,west Shandong uplift,Tanlu fault zone and Jiangsu-Shandong orogenic belt.The low-velocity Pg waves in Dongying depression and Northern Jiangsu basin reveal the unstable basement structure with extremely thick sediments.The travel time of Pg wave is characterized by relatively low propagation velocity and small crustal thickness of offshore continental margin;the first break time and high apparent velocity of Pg wave in west Shandong uplift indicate that the sedimentary basement is relatively thin.The Pm wave shows the characteristic of dominant wave in the first-order velocity discontinuity of the crust-mantle interface,which reflects the high crustal velocity and stable structure in west Shandong uplift.The Pm and Pl wave are obviously complicated,which can reflect the crust-mantle lithospheric structure of the transitional zone between Tanlu fault zone and Jiangsu-Shandong orogenic belt.The small time difference between Pn and PL waves can be regarded as the highly destructive seismological manifestation of Tanlu fault zone on the crust-lithosphere scale.Based on many geophysical phenomena such as electrical structure,density structure and terrestrial heat flow,it is believed that the lithospheric destruction degree of Tanlu fault zone and Jiangsu-Shandong orogenic belt was high during the destruction of the North China Craton. | Zhenyu Fan Jinren Zhao Cejun Ma Mingxin Qu Xiaoguo Deng Baofeng Liu Yan Hai | 2021 | Geodesy and Geodynamics2021，12，2： | 0 |
| 15 | Study on the basement structure in the southeastern North China by blasting seismic显示文摘Since the Mesozoic, southeastern North China Craton has experienced intense crustal thinning and lithosphere destruction. Some of the responses of the deep activity in the upper crust crystalline basement have been retained in a series of tectonic evolution. The study of the upper crust velocity structure,especially the properties of the basement interface, is of great significance for studying the tectonic evolution and seismic hazard in the southeastern part of North China. In this study, we selected Pg waves of the blasting seismic data in the southeastern part of North China in recent years, which reflect the west Shandong uplift, offshore sedimentary basins and the Tanlu Fault zone and the Sulu orogenic transition zone, to study the structural and seismological characteristics of basement in North China Craton. The results of this study showed as follows: First, the obvious lag of Pg wave arrival time in Dongying depression and North Jiangsu basin reveals the thick sedimentary, low velocity and unstable basement structure. Second, the advance Pg wave arrival time with high apparent velocity, which reflects the basement structure of the west Shandong uplift, indicates the thin sediments and the shallow basement. Third, combined with many geophysical phenomena, such as electrical structure, density structure and terrestrial heat flow, we hold that the Tanlu tectonic belt and the Sulu orogenic belt have experienced great lithosphere destruction and there is shallow crust and the thinnest lithosphere in the vicinity of the Tanlu fault zone. | Zhenyu Fan Jinren Zhao Suzhen Pan Cejun Ma Mingxin Qu Yan Hai Xiaoguo Deng | 2018 | Geodesy and Geodynamics2018，9，4： | 0 |
