| 1 | Organic photovoltaic cell with 17% efficiency and superior processability显示文摘The development of organic photoactive materials,especially the newly emerging non-fullerene electron acceptors(NFAs),has enabled rapid progress in organic photovoltaic(OPV)cells in recent years.Although the power conversion efficiencies(PCEs)of the top-performance OPV cells have surpassed 16%,the devices are usually fabricated via a spin-coating method and are not suitable for large-area production.Here,we demonstrate that the fine-modification of the flexible side chains of NFAs can yield 17%PCE for OPV cells.More crucially,as the optimal NFA has a suitable solubility and thus a desirable morphology,the high efficiencies of spin-coated devices can be maintained when using scalable blade-coating processing technology.Our results suggest that optimization of the chemical structures of the OPV materials can improve device performance.This has great significance in larger-area production technologies that provide important scientific insights for the commercialization of OPV cells. | Yong Cui Huifeng Yao Ling Hong Tao Zhang Yabing Tang Baojun Lin Kaihu Xian Bowei Gao Cunbin An Pengqing Bi Wei Ma Jianhui Hou | 2020 | National Science Review2020，7，7： | 7 |
| 2 | Analysis of the ore-controlling structure of the Shihu gold deposit, Hebei Province and deep-seated ore-prospecting prediction显示文摘Under the guidance of the theory of mantle-branch structure-associated metallogenesis and on the basis of the geological characteristics, analysis of the ore-forming and ore-controlling structures, the geochemical characteristics of metallogenesis, the source of ore-forming materials, changes in the physical and chemical conditions of metallogenesis, changes in the vertical width of ore veins, and changes in gold grade of the Shihu gold deposit, the mechanism of its metallogenesis was discussed and the rules of vertical variation of ore veins were summarized in this study. It is pointed out that the orebodies under exploitation at present time should be in the middle and upper portions of gold veins in the Shihu gold mining district. Particularly on the basis of the characteristics of mantle-branch structure-associated metallogenesis, it is indicated that metallogenesis is controlled mainly by such ore-forming conditions as temperature and pressure. Deep-seated ore-forming fluids are characterized mainly by injection and precipitation. So the vein bodies in the adjacent metallogenic structures are of obvious comparability, and there would be great prospects for ore search both at depth and in the periphery of the Shihu gold deposit. Therefore, ore prospecting should be strengthened both at depth and in the peripheries. | NIU Shuyin WANG Baode SUN Aiqun CHEN Chao WANG Zili MA Baojun WANG Wenxue JIANG Xiaoping ZHAO Yongli GAO Yincang LIU Huabin QIU Jianping | 2009 | Chinese Journal Of Geochemistry2009，28，4： | 6 |
| 3 | Suppression of strong random noise in seismic data by using time-frequency peak filtering显示文摘Time-frequency peak filtering (TFPF) is highly efficient in suppressing random noise in seismic data. Although the hypothesis of stationary Gaussian white noise cannot be fulfilled in practical seismic data, TFPF can effectively suppress white and colored random noise with different intensities, as can be theoretically demonstrated by detecting such noise in synthetic seismic data. However, a 'zero-drift' effect is observed in the filtered signal and is independent of the average power and variance of the random noise, but related to its mean value. Furthermore, we consider the situation where the local linearization of the seismic data cannot be satisfied absolutely and study the 'distortion' characteristics of the filtered signal using TFPF on a triangular wave. We found that over-compensation is possible in the frequency band for the triangular wave. In addition, it is nonsymmetrical and has a relationship to the time-varying curvature of the seismic wavelet. The results also present an improved approach for TFPF. | LI Yue YANG BaoJun LIN HongBo MA HaiTao NIE PengFei | 2013 | Science China Earth Sciences2013，56，7： | 5 |
| 4 | Study on the Metallogenetism of Sub-mantle Plume and Mantle Branches in the Gold Mineralization Concentration Area of Northwest Jiaodong Peninsula显示文摘The northwest of Jiaodong peninsula is characterized by its greatest gold concentration area, enormous gold reserves and limited time interval(115±5Ma) of gold mineralization in China. Studies show that the east area of north China began its mantle plume evolution since the Yanshanian movement, and the Laiyang sub-mantle plume and its surrounding mantle branches such as those in Guojiadian, Aishan and Panshidian were formed in the mineralization concentration area of northwestern Jiaodong peninsula. With the development of mantle plume → sub-mantle plume → mantle branch → favorable expending structures, the deep-derived hydrothermal fluid moved up to the favorable places, such as brittle-ductile or ductile-brittle shearing zones, the internal and external contact zones of intrusions, dense fracturing zones and the contact zones between dikes and countryrocks, and concentrated into deposits. Then the gold mineralization concentration zones that are centralized on mantle branches were formed. This study takes Guojiadian mantle branch as an example to discuss their metallogenetism and conclude the metallogenetic mode. | NIU Shuyin CHENG Guangsuo ZHANG Jianzhen SUN Aiqun MA Baojun ZHANG Fuxiang WANG Baode XU Meng WU Jichun ZHAO Rongxin WANG Shanfei | 2014 | Acta Geologica Sinica(English Edition)2014，88，5： | 4 |
| 5 | Factors Controlling Hydrocarbon Accumulation in Jurassic Reservoirs in the Southwest Ordos Basin, NW China显示文摘The sedimentary, paleogeomorphological and reservoir characteristics of the Jurassic Yan’an Formation in the southwestern Ordos Basin, northwestern China, were studied by means of casting thin sections, scanning electron microscopy, inclusion analysis and identification of low-amplitude structures. A model for reservoir formation is established, and the controlling effects of sedimentary facies, paleotopography, low-amplitude structures and formation water on oil reservoirs are revealed. There are significant differences in the sedimentary characteristics, structural morphology and paleowater characteristics between the reservoirs above the Yan 10 Member and those in the Yan 9 to Yan 7 Members. The Yan 10 Member contains fluvial sediments, whereas the Yan 9 to Yan 7 members contain delta-plain anastomosing-river deposits. The distribution of high-permeability reservoir is controlled by pre-Jurassic paleogeomorphology and sedimentary facies. Some of these facies exhibit high porosity and high permeability in a lowpermeability background. The main hydrocarbon accumulation period was the late Early Cretaceous, filling was continuous, and the charging strength altered from weak to strong and then from strong to weak. The Yan 10 reservoir is mainly controlled by the paleogeomorphology: hydrocarbons migrated upward at a high speed through the unconformity surface, and accumulated in the favorable traps formed by paleogeomorphic structural units, such as gentle slopes or channel island. Furthermore, groundwater alternation in these areas was relatively stagnant, providing good reservoir preservation conditions. The reservoirs in the Yan 9 and higher members are controlled by the sedimentary facies, lowamplitude structure and paleowater characteristics. Hydrocarbons migrated through the three-dimensional delivery system, influenced by favorable sedimentary facies and high-salinity groundwater, then accumulated in the favorable low-amplitude structural traps that formed during the hydrocarbon production period. | LIU Xin WANG Feng LIU Baojun TIAN Jingchun SHANG Ting MA Jiong ZHANG Zhongyi ZHANG Xiaolei | 2020 | Acta Geologica Sinica(English Edition)2020，94，2： | 4 |

| 7 | Multiphase microstructure formation and its effect on fracture behavior of medium carbon high silicon high strength steel显示文摘This work investigated the evolution of multiphase microstructure and impact fracture behavior of medium carbon high silicon high strength steel subjected to the austempering treatment at 240,360,and400℃.The results show that martensite,bainite,and retained austenite(RA)are the main microstructural phases.The austempering treatments at 360 and 400℃ caused the formation of carbon-poor ferrite in the matrix,and the transformation of ultrafine bainite into coarse lath bainite and granular bainite,respectively.Thick filmy RA was distributed between bainite laths.The polygonal martensiteaustenite islands and blocky RA formed along the grain boundaries.The average carbon concentration in the matrix decreased with the temperature increase,while the impact toughness initially increased and then dropped with temperature.The quasi-cleavage brittle fracture dominated the impact fracture mechanism of the sample austempered at 240℃ by forming tearing surfaces and tearing steps.The microcracks disappeared in the RA on the prior austenite grain boundaries.On the other side,the fracture surface of the sample austempered at 360℃ exhibited ductile fracture with deep dimples and brittle fracture with cleavage river patterns.The polygonal martensite-austenite islands or blocky RA constrained the microcracks.After austempered at 400℃,the brittle fracture was dominant,showing river patterns,and the microcracks propagated through the granular bainite without any resistance. | Kui Chen Huabing Li Zhouhua Jiang Fubin Liu Congpeng Kang Xiaodong Ma Baojun Zhao | 2021 | Journal of Materials Science & Technology2021，，13： | 3 |
| 8 | Timing of mineralization at the Shihu gold deposit in the middle segment of the Taihang Mountain, China显示文摘The Shihu gold deposit, located in the middlesouth section of the core of the Fuping mantle branch structure, is hosted in the Archean Fuping Group and adjacent to the quartz diorite porphyrite. The gold deposit is the only large gold deposit with reserves of more than 30 tons gold discovered in western Hebei Province so far. In order to constrain the timing of mineralization of this ore deposit, this paper focuses on the isotopic dating of zircon and pyrite. Zircons in gold-bearing quartz veins are magmatic in origin and no hydrothermal zircon has been found in such quartz veins, indicating that zircons were derived from the wall rocks. U–Pb ages of zircons fall mainly in the two domains: 2492 ± 82 and 136 ± 4 Ma, respectively,indicative of the contribution of the Fuping-Group TTG gneiss and Yanshanian igneous rocks, respectively. The Re–Os isotopic compositions of pyrites in the gold-bearing quartz veins yield an isochron age of 127 ± 31 Ma. Combined with other dating results, we suggest that the main metallogenic age of the Shihu gold deposit is 120–127 Ma. | Chao Chen Shuyin Niu Fang Wang Fuxiang Zhang Qinglian Zhang Baojun Ma Aiqun Sun Jianzhen Zhang Yaqi Cao Xiaoqing Zhang | 2018 | Acta Geochimica2018，37，1： | 3 |
| 9 | Study on the ore-forming and ore-controlling structure of the Mujicun Cu (Mo) ore deposit, Hebei Province, China显示文摘The Mujicun Cu (Mo) ore deposit at Laiyuan, Hebei Province, is a currently proven large-sized Cu (Mo) polymetallic ore deposit and it is located in the second-ordered fault depression basin of the ditachment belt on the hanging-wall on the western side at the juncture of the Laiyuan dumbell-shaped complex in the northern part of the Fuping mantle-branch structure. Metallogenesis is controlled by diorite porphyrite in intrusive relation with the fault depression basin and other relevant fault structure systems and intenstive wall-rock alteration zones. This study, in conjunction with the most recent exploration data, analyzed the geological background of metallogenesis of this deposit, summaried the geological characteristics of typical ore deposits, determined the alteration zonation of the deposit, investigated regional metallogenesis and the genesis of typical ore deposits, discussed the regional ore-forming and ore-controlling structures, and generalized the regional ore-controlling model and metallogenic model of the deposit. It is considered that the Mujicun porphry Cu (Mo) deposit, the Tieling, Futuyu, Xiaoligou and other skarn-type Fe-Cu deposits and the He'ergou hydrothermal-type Pb-Zn-Ag deposit jointly constitute a three-in-one polymetallic orefield, with the characteristics of typical metallogenic series. | NIU Shuyin MA Guoxi CHEN Zhikuan WANG Baode CHEN Lijing SUN Aiqun MA Xiaofeng ZHANG Jianzhen MA Baojun CHEN Chao LU Hongpeng | 2012 | Chinese Journal Of Geochemistry2012，31，1： | 2 |
| 10 | Analysis of the ore-controlling role of Guojiadian mantle branch structure,Northwest Shandong Peninsula,China显示文摘Metallogenesis in the gold ore-concentrated zone of Northwest Shandong Peninsula is closely related to deep processes.The region in the eastern part of North China entered into the stage of mantle plume evolution during the Yanshanian movement,following the long-time stage of stable platform evolution during Paleozoic time.At that time,the ore-concentrated zone of Northwest Shandong Peninsula just entered into the development-evolution stage of the Laiyang sub-mantle plume and the Guojiadian mantle branch structure in its periphery.The core-mantle-source gold was present in the gas-liquid form,and it migrated through mantle plume→sub-mantle plume→mantle branch structure→favorable tectonic expansion zone to the favorable loci of the mantle branch structure,where gold was deposited as ores,thereafter constituting a series of large-to medium-sized gold deposits distributed around the Guojiadian mantle branch structure.This study also dealt with the Jiaojia fault as the main detachment(fault altered rock) belt on the northwestern margin of the mantle branch structure and also presented a basic cognition about the fact that the Sanshandao fault as the listric fault on the hanging wall of the detachment belt.Furthermore,on this basis,this study also pointed out the orientation for further ore prospecting in this region. | NIU Shuyin Sun Aiqun ZHANG Jianzhen MA Baojun WANG Baode CHEN Chao ZHANG Fuxiang LIU Cheng ZHANG Xiaofei | 2012 | Chinese Journal Of Geochemistry2012，31，4： | 2 |

| 18 | Metallogenic characteristics of the region of Northwest Hebei and analysis of ore prospecting potential in its peripheries显示文摘The region of Northwest Hebei is an area where Au-Ag polymetallic ore depsits are concentrated in Hebei Province. There were divided the Au ore-concentrated region with the magmatic-metamorphic diamictite zone as the center and the perpheral cover-strata zone and Ag-polymetallic metallogenic zone along the line of Xuanhua-Songli-Chicheng. Research on mantle branch structure indicates that Au-Ag polymetallic ore-forming materials come mainly from the deep interior of the Earth. The ore-forming materials tend to migrate upwards through the multi-stage evolution of mantle plume, and are concentrated as ores in the favourable tectonic expansion zone of a mantle branch structure. As viewed in plane, from the center to the periphery and as viewed in space, from the lower part to the upper part there exists Au-Ag-Pb-Zn zonation, as evidenced by drilling data from a number of mines. So, there is still great potential for ore prospecting in the region of Northwest Hebei. | SUN Aiqun NIU Shuyin WANG Baode HAN Yuchou WEI Minhui MA Baojun ZHAO Zhiyuan XIA Dong | 2011 | Chinese Journal Of Geochemistry2011，30，1： | 1 |
