| 1 | Timing and geochemical characters of the Sanchazi magmatic arc in Mianlüe tectonic zone,South Qinling显示文摘The Sanchazi mafic-ultramafic complex in Mianlüe tectonic zone,South Qinling can be subdivided into two blocks,I.e.Sanchazi paleo-magmatic arc and Zhuangkegou paleo-oceanic crust fragment (ophiolite).The Sanchazi paleo-magmatic arc is mainly composed of ande-site,basaltic and basalt-andesitic gabbro(or diorite),andesitic dyke,plagiogranite and minor ul-tramafric rocks,which have typical geochemical features of island arc volcanic rocks,such as high field strength element(e.g.Nb,Ti)depletions and lower Cr,Ni contents.The Light rare earth element (LREE) and K enrichments of these rocks and zircon xenocrystals of 900 Ma from plagiogranite suggest that this magmatic arc was developed on the South active continental margin of the South Qinling micro-continent.The U-Pb age of (300±61) Ma for zircons from plagiogranite in-dicates that the Mianlüe paleo-oceanic crust was probably subducted underneath the South Qinling micro-continent in Carboniferous.This is consistent with the formation time (309Ma) of the Huwan eclogite originating form oceanic subduction in Dabie Mountains,suggesting that the Mianlüe paleo-ocean probably extended eastward to the Dabie Mountains in Carboniferous.The high-Mg adakitic rocks in Sanchazi paleo-magmatic arc suggest thet the subducted oceanic crust was relatively young (<25Ma) and hot. | LI Shuguang1, HOU Zhenhui1, YANG Yongcheng2, SUN Weidong1,1), ZHANG Guowei3, & LI Qiuli1 1.

| 2 | Genesis of the high gamma sandstone of the Yanchang Formation in the Ordos Basin,China显示文摘Recently, more attention has been paid on the high gamma sandstone reservoirs of the Yanchang Formation in the Ordos Basin, China. These high gamma sandstones have logging characteristics different from conventional sandstones, which influences the identification of sandstone reservoirs. Zhang et al (2010) proposed that the high gamma sandstones of the Yanchang Formation might be the result of re-deposition of homochronous sedimentary tuffs or previous tuffs as a part of the sandstone. However, we present a different viewpoint: 1) few tuffs or tuff debris have been found in the high gamma sandstones of the Yanchang Formation; 2) high gamma (or high Th content) sandstones of Yanchang Formation are not related to either clay minerals or feldspar; 3) the heavy minerals in the sandstone reservoirs of the Yanchang Formation are dominated by zircon, which is characterized by abnormally high Th and U contents, up to 2,163 ppm and 1,362 ppm, respectively. This is sufficient to explain the high gamma anomaly. The conclusion is that the high gamma value of the Yanchang Formation sandstones might be caused by zircon with high Th and U contents in sandstones rather than from the tuff components. | Liu Huaqing Li Xiangbo Liao Jianbo Liu Xianyang | 2013 | Petroleum Science2013，10，1： | 11 |
| 3 | IN SITU PROCESSING OF Al_(2)O_(3) WHISKERS REINFORCED Ti-Al INTERMETALLIC COMPOSITES显示文摘In situ Al2O3 whiskers reinforced Ti-Al intermetallic composites were fabricated at ~1200℃ by reaction sintering of cold-consolidated fllets consisting mainly of Ti, Al, and different additives. The phases and microstructures of the sintered composites were characterized using X-ray diffraction(XRD) and scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy(EDS). The process of synthesis was investigated using differential thermal analysis (DTA). The effects of processing parameters and additives on the microstructures of the composites and the development of whisker were examined. It is found that the morphology of the whisker is strongly influenced by the additives, the exothermal reaction process, and the processing parameters. | F. Wang1,2)*, Z.K. Fan1), and J.F.

| 4 | Simultaneous removal of Cu(Ⅱ) and Cr(Ⅵ) by Mg–Al–Cl layered double hydroxide and mechanism insight显示文摘Mg–Al–Cl layered double hydroxide(Cl-LDH) was prepared to simultaneously remove Cu(Ⅱ)and Cr(VI) from aqueous solution. The coexisting Cu(Ⅱ)(20 mg/L) and Cr(VI)(40 mg/L) were completely removed within 30 min by Cl-LDH in a dosage of 2.0 g/L; the removal rate of Cu(Ⅱ) was accelerated in the presence of Cr(VI). Moreover, compared with the adsorption of single Cu(Ⅱ) or Cr(VI), the adsorption capacities of Cl-LDH for Cu(Ⅱ) and Cr(VI) can be improved by 81.05% and 49.56%, respectively, in the case of coexisting Cu(Ⅱ)(200 mg/L) and Cr(VI)(400 mg/L). The affecting factors(such as solution initial p H, adsorbent dosage, and contact time) have been systematically investigated. Besides, the changes of p H values and the concentrations of Mg^(2+) and Al^(2+)in relevant solutions were monitored. To get the underlying mechanism, the Cl-LDH samples before and after adsorption were thoroughly characterized by X-ray powder diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. On the basis of these analyses, a possible mechanism was proposed. The coadsorption process involves anion exchange of Cr(VI) with Cl-in Cl-LDH interlayer, isomorphic substitution of Mg^(2+) with Cu^(2+), formation of Cu_2Cl(OH)_3precipitation, and the adsorption of Cr(VI) by Cu_2Cl(OH)_3. This work provides a new insight into simultaneous removal of heavy metal cations and anions from wastewater by Cl-LDH. | Xianyang Yue Weizhen Liu Zuliang Chen Zhang Lin | 2017 | Journal of Environmental Sciences2017，29，3： | 6 |
| 5 | Stability control of gob-side entry retained under the gob with close distance coal seams显示文摘In multi-seam mining,the interlayer rock strata between the upper coal seam(UCS)and the lower coal seam(LCS)appear damage and strength weakening after mining the UCS.Ground stability control of the gob-side entry retaining(GER)under the gob with close distance coal seams(CDCS)is faced with difficulties due to little attention to GER under this condition.This paper focuses on surrounding rock stability control and technical parameters design for GER under the gob with CDCS.The floor rock strata damage characteristics after mining the UCS is first evaluated and the damage factor of the interlayer rock strata below the UCS is also determined.Then,a structural mechanics model of GER surrounding rock is set up to obtain the main design parameters of the side-roadway backfill body(SBB)including the maximum and minimum SBB width calculation formula.The optimal SBB width and the water-to-cement ratio of high water quick-setting material(HWQM)to construct the SBB are determined as 1.2 m and 1.5:1.0,respectively.Finally,engineering trial tests of GER are successfully carried out at#5210 track transportation roadway of Xingwu Colliery.Research results can guide GER design under similar mining and geological conditions. | Zizheng Zhang Min Deng Jianbiao Bai Shuai Yan Xianyang Yu | 2021 | International Journal of Mining Science and Technology2021，31，2： | 5 |
| 6 | Development of flexible zinc–air battery with nanocomposite electrodes and a novel separator显示文摘In this paper, we present the development of flexible zinc–air battery. Multiwalled carbon nanotubes(MWCNTs) were added into electrodes to improve their performance. It was found that MWCNTs were effective conductive additive in anode as they bridged the zinc particles. Poly(3,4-ethylenedioxythiophene)polystyrene sulfonate(PEDOT:PSS) was applied as a co-binder to enhance both the conductivity and flexibility. A poly(acrylic acid)(PAA) and polyvinyl alcohol(PVA) coated paper separator was used to enhance the battery performance where the PVP–PAA layer facilitated electrolyte storage. The batteries remained functional under bending conditions and after bending. Multiple design optimizations were also carried out for storage and performance purposes. | Zhiqian Wang Xianyang Meng Zheqiong Wu Somenath Mitra | 2017 | Journal of Energy Chemistry2017，26，1： | 4 |

| 9 | Coupled fluid-thermal investigation on non-ablative thermal protection system with spiked body and opposing jet combined configuration显示文摘In this paper, a Non-Ablative Thermal Protection System(NATPS) with the spiked body and the opposing jet combined configuration is proposed to reduce the aerodynamic heating of the hypersonic vehicle, and the coupled fluid-thermal numerical analysis is performed to study the thermal control performance of the NATPS. The results show that the spiked body pushes the bow shock away from the protected structure and thus reduces the shock intensity and the wall heat flux. In addition, the low temperature gas of the opposing jet separates the high temperature gas behind the shock from the nose cone of the spiked body, ensuring the non-ablative property of the spiked body. Therefore, the NATPS reduces the aerodynamic heating by the reconfiguration of the flow field, and the thermal control efficiency of the system is better than the Thermal Protection System(TPS) with the single spiked body and the single opposing jet. The influencing factors of the NATPS are analyzed. Both increasing the length of the spiked body and reducing the total temperature of the opposing jet can improve the thermal control performance of the NATPS and the nonablative property of the spiked body. However, increasing the heat conductivity coefficient of the spiked body can enhance benefit the non-ablative property of the spiked body, but has little influence on the thermal control performance of the NATPS. | Jie HUANG Weixing YAO Xianyang SHAN | 2019 | Chinese Journal of Aeronautics2019，32，6： | 3 |
| 10 | High-resolution structure-from-motion models covering 160 km-long surface ruptures of the 2021 M_(W)7.4 Madoi earthquake in northern Qinghai-Tibetan Plateau显示文摘The May 222021 M_(W)7.4 Madoi,Qinghai,China earthquake presented a rare opportunity to apply the modern unmanned aerial vehicle(UAV)photography method in extreme altitude and weather conditions to image surface ruptures and near-field effects of earthquake-related surface deformations in the remote Tibet.High-resolution aerial photographs were acquired in the days immediately following the mainshock.The complex surface rupture patterns associated with this event were covered comprehensively at 3-6 cm resolution.This effort represents the first time that an earthquake rupture in the interior of the Qinghai-Tibetan Plateau has been fully and systematically captured by such high-resolution imagery,with an unprecedented level of detail,over its entire length.The dataset has proven valuable in documenting subtle and transient rupture features,such as the significant mole-tracks and opening fissures,which were ubiquitous coseismically but degraded during the subsequent summer storm season.Such high-quality imagery also helps to document with high fidelity the fractures of the surface rupture zone(supplements of this paper),the pattern related to how the faults ruptured to the ground surface,and the distribution of off-fault damage.In combination with other ground-based mapping efforts,the data will be analyzed in the following months to better understand the mechanics of earthquake rupture related to the fault zone rheology,rupture dynamics,and frictional properties along with the fault interface. | Jing Liu-Zeng Wenqian Yao Xiaoli Liu Yanxiu Shao Wenxin Wang Longfei Han Yan Wang Xianyang Zeng Jinyang Li Zijun Wang Zhijun Liu Hongwei Tu | 2022 | Earthquake Research Advances2022，2，2： | 3 |
| 11 | High H_(2) selective performance of Ni-Fe-Ca/H-Al catalysts for steam reforming of biomass and plastic显示文摘The development of a selective catalyst for the conversion of biomass and plastics into H2by steam reforming can combat the energy crisis and global warming.In this work,support Ni-Fe-Ca/H-Al bifunctional catalysts were prepared by loading Ni and Fe into pretreatment CaO/Al_(2)O_(3)(Ca/H-Al)carriers and showed high catalytic activity for the steam reforming of biomass and plastic.Moreover,the idea of bidirectional degradation was exploited to strengthen the pyrolysis of plastic with a high H/C and biomass with a high O/C.Interestingly,the products presented high H2selective(1302.10 m L/g)and low CO_(2)yield(120.23 m L/g)in 7Ni-5Fe-Ca/H-Al(2:4)catalyst compared with current reports.Here,the abundant oxygen vacancies(Ov)in the H-Al carrier exhibited an electron-deficient nature,providing active sites for anchoring Ni O.Meanwhile,Ni O interacted with Ca_(2)Fe_(2)O_(5)to produce more defective Ovsites,which stabilized the NiO particles in the 7Ni-5Fe-Ca/H-Al(2:4)catalyst,and the interaction between the catalyst and the carrier was enhanced,leading to the reduction of weakly basic sites,this property promoted the strong adsorption of CO_(2)and H2O by the catalyst,contributing to the enhancement of efficient steam conversion and the promotion of conversion of by-products to H2.Notably,7Ni-5Fe-Ca/H-Al(2:4)catalysts maintained structural integrity after regeneration and exhibited excellent regenerability in H2selection and CO_(2)adsorption.The work provides a new idea for the study of efficient H2production from steam reforming of biomass and plastics. | Jin Deng Lingshuai Meng Duo Ma Yujie Zhou Xianyang Wang Xiaodong Luo Shenfu Yuan | 2023 | Journal of Energy Chemistry2023，，5： | 2 |
| 12 | Micro-plate magnetic chemiluminescence immunoassay and its applications in carcinoembryonic antigen analysis显示文摘A micro-plate magnetic chemiluminescence immunoassay was developed for rapid and high throughput detection of carcinoembryonic antigens (CEA) in human sera. This method was based on a sandwich immunoreaction of fluorescein isothiocyanate (FITC)-labeled anti-CEA antibodies, CEA antigens, and horseradish peroxidase (HRP)-conjugated anti-CEA antibodies in mi- cro-plate. The immunomagnetic particles coated with anti-FITC antibodies were used as the solid phase for the immunoassay. The separation procedure was carried out by a magnetic plate adaptor and the luminol-hydrogen peroxide (H2O2)-HRP system was employed for the chemiluminescence detection. The proposed method combined the advantages of the micro-plate reactor and magnetic particle separation technology with the linear range of 5-250 ng mL·1. The detection limit of CEA was 0.61 ng mL·1. The coefficient of the variation was less than 7% and 13% for intra-assay and inter-assay precision, respectively. Compared with the commercial micro-plate chemiluminescent kit, the proposed method showed a good correlation. | LI ZhiYong1, ZHANG QianYun2, ZHAO LiXia1, LI ZhenJia3, HU GuoMao3, LIN Jin-Ming2 & WANG Shan4 1State Key Laboratory of Environmental Chemistry and Ecotoxicology, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing 100085, China 2Department of Chemistry, Tsinghua University, Beijing 100084, China 3Beijing Chemclin Biotech Co., Ltd., Beijing Academy of Science and Technology, Beijing 100094, China 4School of Chemistry and Chemical Engineering, Xianyang Normal College, Xianyang 712000, China | 2010 | Science China Chemistry2010，53，4： | 2 |

| 14 | Characteristics and resource prospects of tight oil in Ordos Basin, China显示文摘Efficient large-scale development of ultra-low-permeability reservoirs(0.3-1 mD)has been achieved in the Changqing Oilfield,Ordos Basin of China.According to unique features of petroleum exploration and development in this basin,tight oil herein refers to petroleum that occurs in oil-bearing shales and interbedded tight sandstone reservoirs adjacent to source rocks with ambient air permeability<0.3 mD.Tight oil in tight sandstone and shale have generally not yet experienced large-scale long-distance migration.In the Yanchang Formation,tight oil has mainly accumulated in the semi-deep to deep lacustrine facies,typically in oil-bearing shales and tight sandstones of the 7th member oil-bearing formation and tight sandstones of the 6th member oil-bearing formation in the center of the basin.Tight oil resource in the Ordos Basin is characterized by wide spatial distribution,excellent source rocks,extremely tight sandstone reservoirs,complex pore throat structures,poor physical properties,high oil saturation,good crude-oil properties,and low reservoir pressure.A fundamental feature of the continuous oil and gas accumulation in tight oil reservoirs is the widespread development of nano-scale pore-throat systems.In the Yanchang Formation,most of connected pore throats in tight sandstone reservoirs have diameters greater than critical pore throat diameter,allowing oil and gas migration in the tight reservoirs.According to contact relationship between tight reservoirs and source rocks,three types of tight oil reservoirs are identified in the Yanchang Formation,i.e.,tight massive sandstone reservoir,sand-shale interbed reservoir,and oil-bearing shale reservoir.In the Ordos Basin,tight oil is widely distributed in the 6th and 7th members of the Yanchang Formation,with total resources estimated to be 3×10^(9) t.These include>1×10^(9) t of oil resources in shale in the 7th member of the Yanchang Formation and approximately 0.9×10^(9) t and 1.1×10^(9) t of tight sandstone oil resource in the 6th and 7th members of the Yanchang Formation,respectively.These tight oil resources are the realistic resources addition for the oilfield,which can ensure an annual production of 50×10^(6) t of oil and gas equivalent and maintain long-term stable oil production in the Changqing Oilfield,Ordos Basin,China. | Hua Yang Shixiang Li Xianyang Liu | 2016 | Petroleum Research2016，1，1： | 2 |
