| 1 | Controlling factors for large gas field formation in thrust belt of Kuqa coal derived hydrocarbon foreland basin显示文摘Kuqa depression is a foreland basin developedwith Mesozoic-Triassic-Jurassic coal-bearing formation. Theresearch results of the coal-derived hydrocarbon forelandbasins in Kuqa depression indicated that the coal-bearingformation can be the rich sources for generating gas becauseof their thickness and rich source rocks with gas-generatingpredominant kerogen. Although the foreland thrust beltmainly acting in compression is very complicated, integrallarge structural traps can be formed. Moreover, the thrustbelt can act as the passage for communication with deepsource rocks. The high quality gypsolish and gypseous mud-stone cap rock developed in the upper formation is the keyfor the formation of the large gas field. The late formation ofreservoirs in the large gas fields depended on the hydrocar-bon-generating history controlled by the foreland basin andthe developing process of foreland thrust belt. | SONG Yan JIA Chengzao ZHAO Mengjun TIAN Zuoji | 2002 | Chinese Science Bulletin2002，47，S1： | 20 |
| 2 | Control of neotectonic movement on hydrocarbon accumulation in the Kuqa Foreland Basin,west China显示文摘Neotectonic movement refers to the tectonic movement that has happened since the Cenozoic,which is the latest movement. It has the most important influence on the basins in west China,especially on the hydrocarbon accumulation in the western foreland basins. We determined the time of neotectonic movement in the Kuqa Foreland Basin,which began from the Neogene,and analyzed the patterns of movement,which were continuous and fast subsidence in the vertical direction and intense lateral compression. The structure styles are that the faulting is weakened and the folding is strengthened gradually from north to south. We studied the control of neotectonic movement on the hydrocarbon accumulation process and model in the Kuqa Foreland Basin with basin simulation technique. The largest subsidence rate of the Kuqa Foreland Basin reached 1,200 m/Ma during the neotectonic movement,leading to rapid maturing of source rock within 5 Ma and a large quantity of hydrocarbon being generated and expelled. The thick neotectonic strata can form high quality reservoirs with the proved gas and oil reserves accounting for 5% and 27% of the total reserves,respectively. 86% of the structural traps were formed in the neotectonic movement period. The faults formed during the neotectonic movement serve as important migration pathways and they exist in the region where the hydrocarbon reservoirs are distributed. Abnormally high pressure caused by the intense lateral compression,thick neotectonic strata deposition and rapid hydrocarbon generation provide driving force for hydrocarbon migration. The accumulation elements match each other well over a short period,leading to many large gas fi elds formed later in the Kuqa Foreland Basin. | Jiang Zhenxue Li Lianxia Song Yan Tian Fenghua Zhao Mengjun Wang Haijiang Zhao Zhenxing | 2010 | Petroleum Science2010，7，1： | 6 |
| 3 | Heat Transfer Enhancement with Mixing Vane Spacers Using the Field Synergy Principle显示文摘The single-phase heat transfer characteristics in a PWR fuel assembly are important. Many investigations attempt to obtain the heat transfer characteristics by studying the flow features in a 5×5 rod bundle with a spacer grid. The field synergy principle is used to discuss the mechanism of heat transfer enhancement using mixing vanes according to computational fluid dynamics results, including a spacer grid without mixing vanes, one with a split mixing vane, and one with a separate mixing vane. The results show that the field synergy principle is feasible to explain the mechanism of heat transfer enhancement in a fuel assembly. The enhancement in subchannels is more effective than on the rod's surface. If the pressure loss is ignored, the performance of the split mixing vane is superior to the separate mixing vane based on the enhanced heat transfer. Increasing the blending angle of the split mixing vane improves heat transfer enhancement, the maximum of which is 7.1%. Increasing the blending angle of the separate mixing vane did not significantly enhance heat transfer in the rod bundle, and even prevented heat transfer at a blending angle of 50°. This finding testifies to the feasibility of predicting heat transfer in a rod bundle with a spacer grid by field synergy, and upon comparison with analyzed flow features only, the field synergy method may provide more accurate guidance for optimizing the use of mixing vanes. | YANG Lixin ZHOU Mengjun TIAN Zihao | 2017 | Chinese Journal of Mechanical Engineering2017，30，1： | 3 |
| 4 | Applying generalized hydrophobicity scale of amino acids to quantitative prediction of human leukocyte antigen-A~*0201-restricted cytotoxic T lymphocyte epitope显示文摘Derived from 149 hydrophobic factors of 20 natural amino acids, a novel amino acid descriptor termed as generalized hydrophobicity scale (GH-scale) was proposed by principal component analysis (PCA). Via genetic algorithm-partial least square (GPLS) method, quantitative structure-activity relationship (QSAR) model was constructed by GH-scale for 152 human leukocyte antigen (HLA)-A*0201-restricted cytotoxic T lymphocyte (CTL) epitopes with the model estimated and cross-validated correlative coefficients of R2 = 0.813 and Q2 = 0.725, respectively. It was in- dicated that hydrophobic interaction played an im- portant role in HLA-A*0201-CTL interaction, promi- nently at anchor residues. | ZHOU Peng TIAN Feifei ZHANG Mengjun LI Zhiliang | 2006 | Chinese Science Bulletin2006，51，12： | 2 |
| 5 | The Phytophthora effector Avh241 interacts with host NDR1-like proteins to manipulate plant immunity显示文摘Plant pathogens rely on effector proteins to suppress host innate immune responses and facilitate colonization.Although the Phytophthora sojae RxLR effector Avh241 promotes Phytophthora infection,the molecular basis of Avh241 virulence remains poorly understood.Here we identified non-race specific disease resistance 1(NDR1)-like proteins,the critical components in plant effector-triggered immunity(ETI)responses,as host targets of Avh241.Avh241 interacts with NDR1 in the plasma membrane and suppresses NDR1-participated ETI responses.Silencing of GmNDR1s increases the susceptibility of soybean to P.sojae infection,and overexpression of GmNDR1s reduces infection,which supports its positive role in plant immunity against P.sojae.Furthermore,we demonstrate that GmNDR1 interacts with itself,and Avh241 probably disrupts the self-association of GmNDR1.These data highlight an effective counter-defense mechanism by which a Phytophthora effector suppresses plant immune responses,likely by disturbing the function of NDR1 during infection. | Bo Yang Sen Yang Baodian Guo Yuyin Wang Wenyue Zheng Mengjun Tian Kaixin Dai Zehan Liu Haonan Wang Zhenchuan Ma Yan Wang Wenwu Ye Suomeng Dong Yuanchao Wang | 2021 | Journal of Integrative Plant Biology2021，63，7： | 1 |
| 6 | Fg12 ribonuclease secretion contributes to Fusarium graminearum virulence and induces plant cell death显示文摘Filamentous fungal pathogens secrete effectors that modulate host immunity and facilitate infection. Fusarium graminearum is an important plant pathogen responsible for various devastating diseases. However, little is known about the function of effector proteins secreted by F. graminearum. Herein, we identified several effector candidates in the F. graminearum secretome. Among them, the secreted ribonuclease Fg12 was highly upregulated during the early stages of F. graminearum infection in soybean;its deletion compromised the virulence of F. graminearum. Transient expression of Fg12 in Nicotiana benthamiana induced cell death in a light-dependent manner. Fg12 possessed ribonuclease(RNase) activity, degrading total RNA. The enzymatic activity of Fg12 was required for its cell death-promoting effects. Importantly, the ability of Fg12 to induce cell death was independent of BAK1/SOBIR1, and treatment of soybean with recombinant Fg12 protein induced resistance to various pathogens, including F. graminearum and Phytophthora sojae. Overall, our results provide evidence that RNase effectors not only contribute to pathogen virulence but also induce plant cell death. | Bo Yang Yuyin Wang Mengjun Tian Kaixin Dai Wenyue Zheng Zehan Liu Sen Yang Xinyu Liu Dongya Shi Haifeng Zhang Yan Wang Wenwu Ye Yuanchao Wang | 2021 | Journal of Integrative Plant Biology2021，63，2： | 0 |
| 7 | Application of Activated Carbon in the Removal of COD in Zero-emission Reverse Osmosis Concentrate显示文摘For further reducing the load of subsequent processing,the activated carbon adsorption method was used to remove organic compounds from reverse osmosis water concentrate,and the influence of variety of activated carbon,residence time,dosage of activated carbon and p H on the removal rate of COD was studied.The results show that the removal rate of COD was up to 61.8%under the conditions of influent p H=6,400 ml water,30 min of residence time and 1.5 g of 2#activated carbon as the adsorbent.In the dynamic adsorption experiment and field application,the adsorption tower was loaded with 40 tons of 2#activated carbon,and the inflow of influent water was 100 m^3/h;average COD was 142 mg/L,and p H was 8.04;the residence time was 36 min.Under the above conditions,when effluent COD was less than 60 mg/L,the adsorption capacity of activated carbon was up to 1330 m^3/t. | Li Jun Liu Xiaojing Tian Lei Zhu Haichen Li Mengjun | 2019 | Meteorological and Environmental Research2019，10，6： | 0 |
| 8 | Study on dynamic changes of land desertification in the circum-lake zone of the Qinghai Lake in the past 30 years supported by Remote Sensing and Geographical Information System显示文摘The circum-lake zone of the Qinghai Lake is one of the most serious regions of desertification on the Qinghai-Tibetan Plateau. Based on Remote Sensing(RS) and Geographical Information System(GIS) techniques, the four sets of remote sensing images acquired in 1976, 1987, 1995, and 2006 were selected to conduct thematic information extraction in 14,300 km2 of land in the circum-lake zone using the Earth Resource Data Analysis System(ERDAS) image and information processing function. In the meantime the off-site interpretation and filed check-correction methods were used to reconstruct the temporal-spatial dynamic changes and differentiation patterns of land desertification in the circum-lake zone in the past 30 years, and based on this, the developmental trend of land desertification in the next 20 years was predicted. The results of the study show that in the past 30 years land desertification in the region experienced a continuous fluctuation between rapid- and slow-development processes in time, while in space it exhibited a few small patchy distributions or sporadic distributions in many places while at the same time, four large sand-dominated distributions stood out and evolved into a circum-lake belt differentiation pattern with a lakeside dike as the connecting line. Due to the integrated effects of climate changes, human activities and artificial rehabilitation, land desertification area in the region in the next 20 years will exhibit an increasing trend in the first 15 years and then increase at a slower rate, and afterward occur in a reverse, decreasing trend. | MengJun Hu WenLi Zhang AiLi Yang LiHui Tian DengShan Zhang | 2014 | Research in Cold and Arid Regions2014，6，6： | 0 |
| 9 | Recognition for avian influenza virus proteins based on support vector machine and linear discriminant analysis显示文摘Total 200 properties related to structural characteristics were employed to represent structures of 400 HA coded proteins of influenza virus as training samples. Some recognition models for HA proteins of avian influenza virus (AIV) were developed using support vector machine (SVM) and linear discriminant analysis (LDA). The results obtained from LDA are as follows: the identification accuracy (Ria) for training samples is 99.8% and Ria by leave one out cross validation is 99.5%. Both Ria of 99.8% for training samples and Ria of 99.3% by leave one out cross validation are obtained using SVM model, respectively. External 200 HA proteins of influenza virus were used to validate the external predictive power of the resulting model. The external Ria for them is 95.5% by LDA and 96.5% by SVM, respectively, which shows that HA proteins of AIVs are preferably recognized by SVM and LDA, and the performances by SVM are superior to those by LDA. | LIANG GuiZhao CHEN ZeCong YANG ShanBin MEI Hu ZHOU Yuan YANG Li ZHOU Peng YANG ShengXi SHU Mao LIAO ChunYang WU ShiRong LI GenRong HE Liu GAO JianKun Gan MengYu LI DeJing CHEN GuoPing WANG GuiXue LONG Sha JING JuHua ZHENG XiaoLin ZENG Hui ZHANG QiaoXia ZHANG MengJun YANG Qi TIAN FeiFei TONG JianBo WANG JiaoNa LIU YongHong LI Bo QIU LiangJia CAI ShaoXi ZHAO Na YANG Yan SU XiaLi SONG Jian CHEN MeiXia ZHANG XueJiao SUN JiaYing LI JingWei CHEN GuoHua CHEN Gang DENG Jie PENG ChuanYou ZHU WanPing XU LuoNan WU YuQuan LIAO LiMin LI Zhi LI Jun LU DaJun SU QinLiang HUANG ZhengHu ZHOU Ping LI ZhiLiang | 2008 | Science China Chemistry2008，51，2： | 0 |
| 10 | Design and synthesis of self-included pillar[5]arene-based bis-[1]rotaxanes显示文摘Two strategies for the design of new pillar[5]arene-based mechanically self-interlocked molecules (MSMs) are reported here. The first strategy is based on the construction of an intermediate pseudo[1]rotaxane followed by the desired bis-[l]rotaxane. The other one is based on the construction of the desired bis-[1]rotaxane directly via a condensation reaction through host-guest interactions between a mono-functionalized pillar[5]arene and the axle. The newly synthesized bis-[1]rotaxane BR was characterized by ~1H NMR, ^(13)C NMR, 2D NMRs (~1H-^(13)C HSQC,~1H-~1H COSY and NOESY) and LC-ESI-MS,which indicated compound BR displayed an self-interlocked structure in CDCl_3. Surprisingly, the results of SEM, TEM and DLS showed that the compound BR could assemble into spherical nanoparticles in MeOH. | Mengjun Wang Xusheng Du Huasheng Tian Qiong Jia Rong Deng Yahan Cui Chunyu Wang Kamel Meguellati | 2019 | Chinese Chemical Letters2019，30，2： | 0 |
| 11 | Ultra‐low single‐atom Pt on g‐C_(3)N_(4)for electrochemical hydrogen peroxide production显示文摘Platinum-based materials show excellent electrocatalytic performance and have good potential for use in fuel cells.However,the high cost and scarce reserves have restricted their wide application.Therefore,it is a challenging task to reduce the amount of Pt as well as ensure good catalytic performance.Herein,anchoring of Pt single atoms(0.21 wt‰)with ultra-low content on g-C_(3)N_(4)nanosheets(Pt_(0.21)/CN)has been successfully achieved.The obtained Pt_(0.21)/CN catalyst shows excellent two-electron oxygen reduction(2e-ORR)capability for hydrogen peroxide(H_(2)O_(2)).Compared with CN,its H_(2)O_(2)selectivity increased from 80%to 98%in 0.1M KOH,surpassing those in most of the reported studies.Besides,the H_(2)O_(2)production rate of Pt_(0.21)/CN is 767 mmol gcat^(-1)h-1,which is 11.1 times that of CN.This work may pave the way toward the development of an effective method for the design of noblemetal electrocatalysts with low metal loading and high catalytic activity. | Hongcen Yang Niandi Lu Juntao Zhang Rui Wang Shuhao Tian Mengjun Wang Zhixia Wang Kun Tao Fei Ma Shanglong Peng | 2023 | Carbon Energy2023，5，9： | 0 |
