| 1 | Geology and hydrocarbon accumulations in the deepwater of the northwestern South China Sea——with focus on natural gas显示文摘The deepwater of the northwestern South China Sea is located in the central to southern parts of the Qiongdongnan Basin(QDN Basin),which is a key site for hydrocarbon exploration in recent years.In this study,the authors did a comprehensive analysis of gravity-magnetic data,extensive 3D seismic survey,cores and cuttings,paleontology and geochemical indexes,proposed the mechanism of natural gas origin,identified different oil and gas systems,and established the model of hydrocarbon accumulations in the deep-water region.Our basin tectonic simulation indicates that the evolution of QDN Basin was controlled by multiple-phased tectonic movements,such as Indochina-Eurasian Plate collision,Tibetan Uplift,Red River faulting and the expansion of the South China Sea which is characterized by Paleogene rifting,Neogene depression,and Eocene intensive faulting and lacustrine deposits.The drilling results show that this region is dominated by marineterrestrial transitional and neritic-bathyal facies from the early Oligocene.The Yacheng Formation of the early Oligocene is rich in organic matter and a main gas-source rock.According to the geological-geochemical data from the latest drilling wells,Lingshui,Baodao,Changchang Sags have good hydrocarbon-generating potentials,where two plays from the Paleogene and Neogene reservoirs were developed.Those reservoirs occur in central canyon structural-lithologic trap zone,Changchang marginal trap zone and southern fault terrace of Baodao Sag.Among them,the central canyon trap zone has a great potential for exploration because the various reservoirforming elements are well developed,i.e.,good coal-measure source rocks,sufficient reservoirs from the Neogene turbidity sandstone and submarine fan,faults connecting source rock and reservoirs,effective vertical migration,late stage aggregation and favorable structural–lithological composite trapping.These study results provide an important scientific basis for hydrocarbon exploration in this region,evidenced by the recent discovery of the significant commercial LS-A gas field in the central canyon of the Lingshui Sag. | WANG Zhenfeng SUN Zhipeng ZHANG Daojun ZHU Jitian LI Xushen HUANG Baojia GUO Minggang JIANG Rufeng | 2015 | Acta Oceanologica Sinica2015，34，10： | 9 |
| 2 | The effects of Haversian fluid pressure and harmonic axial loading on the poroelastic behaviors of a single osteon显示文摘In order to well understand the mechanism of the mechanotransduction in bone,we propose a new model of transverse isotropic and poroelastic osteon cylinder considering Haversian fluid pressure.The analytical pore pressure and velocity solutions are obtained to examine the fluid transport behavior and pressure distribution in a loaded osteon on two different exterior surface cases.Case I is stress free and fully permeable and case II is impermeable.The following are the results obtained.(i) The Haversian fluid may not be ignored because it can enlarge the whole osteonal fluid pressure field,and it bears the external loads together with the solid skeleton.(ii) The increase of both axial strain amplitude and frequency can result in the increase of fluid pressure and velocity amplitudes,while in case II,the frequency has little effect on the fluid pressure amplitude.(iii) Under the same loading conditions,the pressure amplitude in case II is larger than that in case I,while the velocity amplitude is smaller than that in case I.This model permits the linking of the external loads to the osteonal fluid pressure and velocity,which may be a stimulus to the mechanotransduction of bone remodeling signals. | WU XiaoGang CHEN WeiYi GAO ZhiPeng GUO HongMei WANG LiLi | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，9： | 7 |
| 3 | Determination of Interfacial Heat Transfer Behavior at the Metal/Shot Sleeve of High Pressure Die Casting Process of AZ91D Alloy显示文摘The interfacial heat transfer behavior at the metal/shot sleeve interface in the high pressure die casting(HPDC) process of AZ91 D alloy is carefully investigated.Based on the temperature measurements along the shot sleeve,inverse method has been developed to determine the interfacial heat transfer coefficient in the shot sleeve.Under static condition,Interfacial heat transfer coefficient(IHTC) peak values are 11.9,7.3,8.33 k W m^(-2)K^(-1)at pouring zone(S2),middle zone(S5),and end zone(S10),respectively.During the casting process,the IHTC curve displays a second peak of 6.1 k W m^(-2)K^(-1)at middle zone during the casting process at a slow speed of 0.3 m s^(-1).Subsequently,when the high speed started,the IHTC curve reached a second peak of 12.9 k W m^(-2)K^(-1)at end zone.Furthermore,under different slow casting speeds,both the calculated initial temperature(TIDS) and the maximum temperature(Tsimax) of shot sleeve surface first decrease from 0.1 m s^(-1)to 0.3 m s^(-1),but increase again from 0.3 m s^(-1)to 0.6 m s^(-1).This result agrees with the experimental results obtained in a series of 'plate-shape' casting experiments under different slow speeds,which reveals that the amount of ESCs decreases to the minimum values at 0.3 m s^(-1)and increase again with the increasing casting slow speed. | Wenbo Yu Yongyou Cao Xiaobo Li Zhipeng Guo Shoumei Xiong | 2017 | Journal of Materials Science & Technology2017，33，1： | 7 |
| 4 | Determination of interfacial heat transfer coefficient and its application in high pressure die casting process显示文摘In this paper,the research progress of the interfacial heat transfer in high pressure die casting(HPDC)is reviewed.Results including determination of the interfacial heat transfer coefficient(IHTC),influence of casting thickness,process parameters and casting alloys on the IHTC are summarized and discussed.A thermal boundary condition model was developed based on the two correlations:(a)IHTC and casting solid fraction and(b)IHTC peak value and initial die surface temperature.The boundary model was then applied during the determination of the temperature field in HPDC and excellent agreement was found. | Cao Yongyou Guo Zhipeng Xiong Shoumei | 2014 | China Foundry2014，11，4： | 6 |
| 5 | Topological domain states and magnetoelectric properties in multiferroic nanostructures显示文摘Multiferroic nanostructures have been attracting tremendous attention over the past decade, due to their rich cross-coupling effects and prospective electronic applications. In particular, the emergence of some exotic phenomena in size-confined multiferroic systems, including topological domain states such as vortices, center domains, and skyrmion bubble domains, has opened a new avenue to a number of intriguing physical properties and functionalities, and thus underpins a wide range of applications in future nanoelectronic devices. It is also highly appreciated that nano-domain engineering provides a pathway to control the magnetoelectric properties, which is promising for future energy-efficient spintronic devices. In recent years, this field, still in its infancy, has witnessed a rapid development and a number of challenges too.In this article, we shall review the recent advances in the emergent domain-related exotic phenomena in multiferroic nanostructures. Specific attention is paid to the topological domain structures and related novel physical behaviors as well as the electric-field-driven magnetic switching via domain engineering. This review will end with a discussion of future challenges and potential directions. | Guo Tian Wenda Yang Deyang Chen Zhen Fan Zhipeng Hou Marin Alexe Xingsen Gao | 2019 | National Science Review2019，6，4： | 4 |
| 6 | Effects of regulated deficit irrigation on soil salinity,physiological processes and fruit quality of gray jujube under desert conditions显示文摘Regulated deficit irrigation(RDI)was applied to gray jujube trees in an oasis region,to determine the effects of this irrigation system on soil salinity,gray jujube physiological processes,fruit yield,and fruit quality.Treatments consisted of severe,moderate and low deficit irrigation(irrigated with 85%,70%and 55%of CK,respectively)at the flowering stage to fruit set stage.During the other growth stages,all treatments were irrigated with 80%of pan evaporation,which was the same as that in control.The results indicated that soil salinity was enhanced during the periods of water stress,but the high value of soil salinity declined by 3.48%-37.27%,at each depth,after irrigation was resumed.RDI caused a decline in the photosynthetic rate,transpiration rate,and stomatal conductance,but enhanced the water use efficiency of the leaves.However,the leaf photosynthetic rate was effectively enhanced after the recovery of irrigation,especially in the moderate deficit irrigation treatment,which exceeded the control.This led to an improved fruit yield,which was 9.57%higher than that of the control.The deficit treatments caused a significant increase in the soluble solid content,soluble sugar content,single fruit weight and sugar/acid ratio.Enhanced vitamin C content,resulting from deficit treatments,has also been observed in the gray jujube.Therefore,this research shows that RDI provides some benefits in the production of gray jujube trees in desert conditions. | Zhipeng Liu Chengli Zhu Shuyu Wu Weihua Guo Yitikaer Abudushalamu Xiyun Jiao Shipei Gao Jie Wang | 2019 | International Journal of Agricultural and Biological Engineering2019，12，3： | 3 |
| 7 | Immobilization and transformation of co-existing arsenic and antimony in highly contaminated sediment by nano zero-valent iron显示文摘Arsenic(As)and antimony(Sb)are usually coexistent in mine wastes and pose a great threat to human health.The As immobilization by nano zero-valent iron(n ZVI)is promising,however,the stabilization for co-occurring As and Sb is not known.Herein,the immobilization and transformation of As and Sb in n ZVI-treated sediments were evaluated using complementary leaching experiments and characterization techniques.Raw sediment samples from a gold-antimony deposit revealed the co-existence of ultrahigh As and Sb at 50.3 and 14.9 g/kg,respectively.Leaching results show that As was more efficiently stabilized by n ZVI than Sb,which was primarily due to the soluble fraction that was readily absorbed by n ZVI of As was higher.As the n ZVI treatment proceeds,the oxidation and reduction of As and Sb occur simultaneously as evidenced by XPS analysis.The primary oxidant,hydroxyl radicals,was detected by EPR studies,proving the occurrence of n ZVI induced Fenton reaction.This study sheds light on differences in the interaction and immobilization of n ZVI with Sb and As in co-contaminated sediments. | Jianlong Guo Zhipeng Yin Wen Zhong Chuanyong Jing | 2022 | Journal of Environmental Sciences2022，34，2： | 3 |
| 8 | Myocardin-related transcription factor A is up-regulated by 17β-estradiol and promotes migration of MCF-7 breast cancer cells via transactivation of MYL9 and CYR61显示文摘证据的许多线建议了雌激素不仅在乳癌的开始和增长,而且在癌症转移起重要作用。然而,后者事件的机械学的基础糟糕被理解。另外,最近的研究建议了那 myocardin 相关的抄写因素 A (MRTF -- 一) 可能与癌症有关转移。然而报告是矛盾的它的角色肯定尚待糊涂。在现在的学习,我们证明过多的 17-estradiol 能支持 MCF-7 乳癌房间和起来调整的迁居 MRTF 的表示 -- 一,肌浆球蛋白规章的轻链 9 (MYL9 ) ,并且充满半胱氨酸的 angiogenic inducer 61 (CYR61 ) 。MRTF 的 Overexpression -- A 显著地在 MYL9 和 CYR61 基因上通过它的 transactivation 效果支持了 MCF-7 房间的移植,当时 RNA 调停干扰 MRTF 击倒 -- A 强烈禁止了目标基因的抄写和表示并且减少了 MCF-7 房间的移植能力。这些结果提供了支持 MRTF 的支持转移的功能的新奇证据 -- 一,并且暗示了那 MRTF -- A 可能是一个开关让雌激素小径在乳癌把它的支持增长的角色变成刺激迁居的角色。 | Chunling Zhang | 2013 | Acta Biochimica et Biophysica Sinica2013，45，11： | 3 |
| 9 | Reservoir forming conditions and key exploration technologies of Lingshui 17-2 giant gas field in deepwater area of Qiongdongnan Basin显示文摘On September 15,2014,China National Offshore Oil Co.,Ltd announced that a high production of oil and gas flow of 1.6106 m3/d was obtained in Well LS17-2-1 in deepwater area in northern South China Sea,which is the first great oil and gas discovery for self-run deepwater exploration in China sea areas,and a strategic breakthrough was made in natural gas exploration in deepwater area of Lingshui sag in Qiongdongnan Basin.Under the combined action of climax of international deepwater exploration,high oil prices,national demands of China,practical needs of exploration,breakthroughs in seismic exploration and testing technologies,innovations in geological cognition and breakthroughs in deepwater operation equipment,Lingshui 17-2 gas field is discovered.Among these factors,the innovation in reservoir forming geological cognition directly promotes the discovery.The quality of seismic data in the early time is poor,so key reservoir forming conditions such as effective source rocks,high quality reservoirs and oil-gas migration pathways are unable to be ascertained;with support of new seismic acquisition and processing technology,some researches show that Lingshui sag is a successive large and deep sag with an area of 5000 km2 and the maximum thickness of Cenozoic stratum of 13 km.In the Early Oligocene,the Lingshui sag was a semi-closed delta-estuarine environment,where the coalmeasure and marine mudstones in Lower Oligocene Yacheng Formation were developed.The Lingshui sag is a sag with high temperature,and the bottom temperature of source rocks in Yacheng Formation can exceed 250C,but the simulation experiment of hydrocarbon generation at high temperature indicates that the main part of this set of source rock is still in the gas-generation window,with resources of nearly 1 trillion cubic meters,so the Lingshui sag is a hydrocarbon-rich generation sag.In the Neogene,the axial canyon channel from the Thu Bon River in Vietnam passed through the Lingshui sag,and five stages of secondary channels were developed in the axial canyon channel,where four types of reservoirs with excellent physical properties including the axial sand,lateral accretion sand,natural levee sand as well as erosion residual sand were developed,and lithologic traps or structural-lithologic traps were formed.The diapiric zone in the southern Lingshui sag connects deep source rocks in Yacheng Formation and shallow sandstones in the channels,and the migration pattern of natural gas is a T-type migration pattern,in other words,the natural gas generated from Yacheng Formation migrates vertically to the interior of the channel sandbody,and then migrates laterally in the channel reservoirs and forms the reservoirs.Innovations of geophysical exploration technologies for complicated geological conditions of deepwater areas are made,such as the detuning comprehensive quantitative amplitude hydrocarbon detection technology,which greatly improves the success rate of deepwater exploration;key technologies of deepwater safety exploratory well testing represented by the platform-dragged riser displacement technology are developed,which greatly reduces the drilling test cost.The above key exploration technologies provide a strong guarantee for the efficient exploration and development of Lingshui gas field. | Yuhong Xie Gongcheng Zhang Zhipeng Sun Qingbo Zeng Zhao Zhao Shuai Guo | 2019 | Petroleum Research2019，4，1： | 3 |
| 10 | Study on Drag and Noise Reduction of Bionic Blade of Centrifugal Pump and Mechanism显示文摘In order to study the relationship between the important parameters of internal flow and the effect of drag and noise reduction,the internal flow field and sound field characteristics of bionic centrifugal pump are studied in this paper.Based on the methods of theoretical analysis,numerical simulation and test,the relationship between wall average shear stress,drag reduction rate,increasing efficiency and noise reduction rate of internal sound field is studied.Internal flow parameters to judge and predict the effect of drag and noise reduction are revealed.The results show that the bionic pit can effectively increase the thickness of the boundary layer and reduce the Reynolds stress on the wall.The resistance on the wall is reduced and the hydraulic efficiency of the centrifugal pump is increased.The noise reduction rate is basically consistent with the changing trend of the drag reduction rate,increasing efficiency and wall average shear stress in the flow field.Wall average shear stress can reveal the effect of drag and noise reduction,so the effect of drag and noise reduction can be predicted and judged by the change of wall average shear stress. | Cui Dai Chao Guo Zhipeng Ge Houlin Liu Liang Dong | 2021 | Journal of Bionic Engineering2021，18，2： | 3 |
| 11 | Seasonal variation analysis of atmospheric CH_4,N_2O and CO_2 in Tianjin offshore area显示文摘The concentrations of CH4, N2O and CO2 at the sea level were observed from November 2007 to August 2008 in order to study the greenhouse gases in the Tianjin offshore area of Bohai Sea. CH4 concentrations varied from 1.87 to 2.61 ppm with the highest value appearing in summer and the lowest in winter. The concentration range of N2O was 319.3 to 347.7 ppb, with the maximal value appearing in winter. CO2 was higher in the heating season than in non-heating season in this area. Concentrations of the three greenhouse gases in the study area exceeded the 2005 global background values. Backward trajectory model was used to analyze the sources. All three gases were influenced evidently by continental sources in the inshore area during the sampling periods. Every gas was compared with each other by correlation analysis, showing that the correlation of CO2 and N2O was more significant than to CH4 and their relationship with meteorological factors was consistent. It can be concluded these three greenhouse gases may be influenced by some similar sources, especially for CO2 and N2O. | KONG ShaoFei, LU Bing, HAN Bin, BAI ZhiPeng, XU Zhun, YOU Yan, JIN LiangMao, GUO XiaoYang & WANG Rui State Environmental Protection Key Laboratory of Urban Ambient Air Particulate Matter Pollution Prevention and Control, College of Environmental Science and Engineering, Nankai University, Tianjin 300071, China | 2010 | Science China Earth Sciences2010，53，8： | 2 |
| 12 | Short body length phenotype is compensated by the upregulation of nidogen family members in a deleterious nid1a mutation of zebrafish显示文摘To decode biological processes,interfering with gene functions is a widely used strategy.There are a number of ways to interfere with gene functions.For instance,small interfering RNAs(siRNAs)are used to induce mRNA degradation;morpholinos are used to block protein translation(Nasevicius and Ekker,2000);CRISPR interference/inactive CRISPR-associated 9 nuclease(CRISPR-i/dCas9)is used to block mRNA transcription(Qi et al.,2013); | Peipei Zhu Zhipeng Ma Liwei Guo Wei Zhang Qinghe Zhang Ting Zhao Kunpeng Jiang Jinrong Peng Jun Chen | 2017 | Journal of Genetics and Genomics2017，44，11： | 2 |
| 13 | Superflexible and Lead-Free Piezoelectric Nanogenerator as a Highly Sensitive Self-Powered Sensor for Human Motion Monitoring显示文摘For traditional piezoelectric sensors based on poled ceramics,a low curie tem-perature(T_(c))is a fatal flaw due to the depolarization phenomenon.However,in this study,we find the low T_(c) would be a benefit for flex-ible piezoelectric sensors because small alterations of force trig-ger large changes in polarization.BaTi_(0.88)Sn_(0.12)O_(3)(BTS)with high piezoelectric coefficient and low T_(c) close to human body temperature is taken as an example for materials of this kind.Continuous piezo-electric BTS films were deposited on the flexible glass fiber fabrics(GFF),self-powered sensors based on the ultra-thin,superflexible,and polarization-free BTS-GFF/PVDF composite piezoelectric films are used for human motion sensing.In the low force region(1-9 N),the sensors have the outstanding performance with voltage sensitivity of 1.23 V N^(−1) and current sensitivity of 41.0 nA N^(−1).The BTS-GFF/PVDF sensors can be used to detect the tiny forces of falling water drops,finger joint motion,tiny surface deformation,and fatigue driving with high sensitivity.This work provides a new paradigm for the preparation of superflexible,highly sensitive and wearable self-powered piezoelectric sensors,and this kind of sensors will have a broad application prospect in the fields of medical rehabilitation,human motion monitoring,and intelligent robot. | Di Yu Zhipeng Zheng Jiadong Liu Hongyuan Xiao Geng Huangfu Yiping Guo | 2021 | Nano-Micro Letters2021，13，8： | 2 |
| 14 | Reductive Amination of Carbonyl Compounds with Ammonia and Hydrogenation of Nitriles to Primary Amines with Heterogeneous Cobalt Catalysts显示文摘Reductive amination of aldehydes/ketones with aqueous NH3 and hydrogenation of nitriles to primary amines with Co catalysts were reported. Co@NC-700 exhibited remarkable activity and high selectivity for the reductive amination of aldehydes/ketones with aqueous NH3 and the hydrogenation of nitriles to primary amines. Several primary amines can be obtained with good to excellent yields via the reductive amination of aldehydes/ketones and the hydrogenation of nitriles. The nitrogen-doped carbon(C)-supported Co@NC-700 metal catalyst was prepared via the pyrolysis of bioMOF Co/adenine in activated C. Co@NC-700 can be reused five times without evident loss of activity. | LIU Junmei GUO Wanwan SUN Hao LI Ruyue FENG Zhipeng ZHOU Xuyang HUANG Jun | 2019 | Chemical Research in Chinese Universities2019，35，3： | 2 |
| 15 | Meiotic Chromosome Behavior in a Human Male t(8;15)Carrier显示文摘Reciprocal translocation is one of the most common structural chromosomal rearrangements in human beings;it is widely recognized to be associated with male infertility.This association is mainly based on the abnormal chromosome behavior of the translocated chromosomes and sex chromosomes during meiosis prophase I in reciprocal translocation carriers.However,the underlying mechanisms are not completely known.Here we report a reciprocal translocation carrier of t(8;15),who is oligozoospermic due to apoptosis of primary spermatocytes and to premature germ cell desquamation from seminiferous tubules.Further analysis showed abnormal synapsis and recombination frequency in this patient,indicating a connection between chromosome behavior and apoptosis of primary spermatocytes.We also compared these observations with recently reported findings on spermatogenesis defects in reciprocal translocation carriers,and discuss the possible mechanisms underlying bom common and unique phenotypes of reciprocal translocations involving different chromosomes with the aim of further understanding the regulation of human spermatogenesis. | Hanwei Jiang Liu Wang Yingxia Cui Zhipeng Xu Tonghang Guo Dongkai Cheng Peng Xu Wen Yu Qinghua Shi | 2014 | Journal of Genetics and Genomics2014，41，3： | 2 |
| 16 | Bayesian method for system reliability assessment of overlapping pass/fail data显示文摘For high reliability and long life systems, system pass/fail data are often rare. Integrating lower-level data, such as data drawn from the subsystem or component pass/fail testing,the Bayesian analysis can improve the precision of the system reliability assessment. If the multi-level pass/fail data are overlapping,one challenging problem for the Bayesian analysis is to develop a likelihood function. Since the computation burden of the existing methods makes them infeasible for multi-component systems, this paper proposes an improved Bayesian approach for the system reliability assessment in light of overlapping data. This approach includes three steps: fristly searching for feasible paths based on the binary decision diagram, then screening feasible points based on space partition and constraint decomposition, and finally simplifying the likelihood function. An example of a satellite rolling control system demonstrates the feasibility and the efficiency of the proposed approach. | Zhipeng Hao Shengkui Zeng Jianbin Guo | 2015 | Journal of Systems Engineering and Electronics2015，26，1： | 2 |
