| 1 | Ni/Al_2O_3 catalysts for syngas methanation: Effect of Mn promoter显示文摘Ni/Al2O3 catalysts with different amounts of manganese ranging from 1 to 3 wt% as promoter were prepared by co-impregnation method. The catalysts were characterized by N2 physisorption, XRD, TPR, SEM and TEM. Their catalytic activity towards syngas methanation reaction was also investigated using a fixed-bed integral reactor. It was demonstrated that the addition of manganese to Ni/Al2O3 catalysts can increase the catalyst surface area and average pore volume, but decrease NiO crystallite size, leading to higher activity and stability. The effects of reaction temperature, pressure and weight hourly space velocity (WHSV) on carbon oxides conversion and CH4 formation rate were also studied. High carbon oxides conversion, CH4 selectivity and formation rate were achieved at the reaction temperature range of 280 300℃. | Anmin Zhao Weiyong Ying Haitao Zhang Hongfang Ma Dingye Fang | 2012 | Journal of Natural Gas Chemistry2012，21，2： | 15 |
| 2 | Interannual Variability of Late-spring Circulation and Diabatic Heating over the Tibetan Plateau Associated with Indian Ocean Forcing显示文摘The thermal forcing of the Tibetan Plateau(TP) during boreal spring,which involves surface sensible heating,latent heating released by convection and radiation flux heat,is critical for the seasonal and subseasonal variation of the East Asian summer monsoon.Distinct from the situation in March and April when the TP thermal forcing is modulated by the sea surface temperature anomaly(SSTA) in the North Atlantic,the present study shows that it is altered mainly by the SSTA in the Indian Ocean Basin Mode(IOBM) in May,according to in-situ observations over the TP and MERRA reanalysis data.In the positive phase of the IOBM,a local Hadley circulation is enhanced,with its ascending branch over the southwestern Indian Ocean and a descending one over the southeastern TP,leading to suppressed precipitation and weaker latent heat over the eastern TP.Meanwhile,stronger westerly flow and surface sensible heating emerges over much of the TP,along with slight variations in local net radiation flux due to cancellation between its components.The opposite trends occur in the negative phase of the IOBM.Moreover,the main associated physical processes can be validated by a series of sensitivity experiments based on an atmospheric general circulation model,FAMIL.Therefore,rather than influenced by the remote SSTAs of the northern Atlantic in the early spring,the thermal forcing of the TP is altered by the Indian Ocean SSTA in the late spring on an interannual timescale. | Yu ZHAO Anmin DUAN Guoxiong WU | 2018 | Advances in Atmospheric Sciences2018，35，8： | 8 |
| 3 | Characterising the nature, evolution and origin of detachment fault in central depression belt, Qiongdongnan Basin of South China Sea: evidence from seismic reflection data显示文摘Using regional geological, newly acquired 2D and 3D seismic, drilling and well log data, especially 2D long cable seismic profiles, the structure and stratigraphy in the deep-water area of Qiongdongnan Basin are interpreted. The geometry of No.2 fault system is also re-defined, which is an important fault in the central depression belt of the deep-water area in the Qiongdongnan Basin by employing the quantitative analysis techniques of fault activity and backstripping. Furthermore, the dynamical evolution of the No.2 fault system and its controls on the central depression belt are analyzed. This study indicates that the Qiongdongnan Basin was strongly influenced by the NW-trending tensile stress field during the Late Eocene. At this time, No.2 fault system initiated and was characterized by several discontinuous fault segments, which controlled a series small NE-trending fault basins. During the Oligocene, the regional extensional stress field changed from NW-SE to SN with the oceanic spreading of South China Sea, the early small faults started to grow along their strikes, eventually connected and merged as the listric shape of the No.2 fault system as observed today. No.2 fault detaches along the crustal Moho surface in the deep domain of the seismic profiles as a large-scale detachment fault. A large-scale rollover anticline formed in hanging wall of the detachment fault. There are a series of small fault basins in both limbs of the rollover anticline, showing that the early small basins were involved into fold deformation of the rollover anticline. Structurally, from west to east, the central depression belt is characterized by alternatively arranged graben and half-graben. The central depression belt of the Qiongdongnan Basin lies at the extension zone of the tip of the V-shaped northwestern ocean sub-basin of the South China Sea, its activity period is the same as the development period of the northwestern ocean sub-basin, furthermore the emplacement and eruption of magma that originated from the mantle below the Moho surface occurred at the region between Songnan-Baodao and Changchang sags, from east to west with the early-stage spreading of the South China Sea. Therefore, this study not only helps in depicting the structural features and evolution of the deep-water basin in the Qiongdongnan Basin, but also provides the geological and structural evidence for establishing a unified model of continental margin extension and oceanic spreading. | REN Jianye ZHANG Daojun TONG Dianjun HUANG Anmin WANG Yahui LEI Chao ZUO Qianmei ZHAO Yanghui HE Weijun YANG Linlong | 2014 | Acta Oceanologica Sinica2014，33，12： | 8 |
| 4 | Atmospheric heat source/sink dataset over the Tibetan Plateau based on satellite and routine meteorological observations显示文摘The Tibetan Plateau(TP),acting as a large elevated land surface and atmospheric heat source during spring and summer,has a substantial impact on regional and global weather and climate.To explore the multi-scale temporal variation in the thermal forcing effect of the TP,here we calculated the surface sensible heat and latent heat release based on 6-h routine observations at 80(32)meteorological stations during the period 1979–2016(1960–2016).Meanwhile,in situ air-column net radiation cooling during the period 1984–2015 was derived from satellite data.This new data-set provides continuous,robust,and the longest observational atmospheric heat source/sink data over the third pole,which will be helpful to better understand the spatial-temporal structure and multi-scale variation in TP diabatic heating and its influence on the earth’s climatic system. | Anmin Duan Senfeng Liu Yu Zhao Kailun Gao Wenting Hu | 2018 | Big Earth Data2018，2，2： | 7 |

Our results imply that the entanglement evolution depends not only on the coupling strength and thetunneling elements of the environment but also on the number of the freedom degrees and the initial state of the environment. | MA XiaoSan REN MingFan ZHAO GuangXing WANG AnMin | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，10： | 4 |
| 6 | Broadband photodetector of high quality SbS nanowire grown by chemical vapor deposition显示文摘Low dimensional semiconductors can be used for various electronic and optoelectronic devices because of their unique structure and property.In this work,one-dimensional Sb2 S3 nanowires(NWs)with high crystallinity were grown via chemical vapor deposition(CVD)technique on SiO2/Si substrates.The Sb2 S3 NWs exhibited needle-like structures with inclined cross-sections.The lengths of Sb2S3 nanowires changed from 7 to 13μm.The photodetection properties of Sb2 S3 nanowires were comprehensively and systematically characterized.The Sb2S3 photodetectors show a broadband photoresponse ranging from ultraviolet(360 nm)to near-infrared(785 nm).An excellent specific detectivity of 2.1×10^(14)Jones,high external quantum efficiency of 1.5×10^(4)%,sensitivity of 2.2×10^(4)cm^(2)W^(-1)and short response time of less than 100 ms was achieved for the Sb2 S3 NW photodetectors.Moreover,the Sb2S3 NWs showed outstanding switch cycling stability that was beneficial to the practical applications.The high-quality Sb2S3 nanowires fabricated by CVD have great application potential in semiconductor and optoelectronic fields. | Kun Ye Bochong Wang Anmin Nie Kun Zhai Fusheng Wen Congpu Mu Zhisheng Zhao Jianyong Xiang Yongjun Tian Zhongyuan Liu | 2021 | Journal of Materials Science & Technology2021，，16： | 3 |
| 7 | Discovery of carbon-based strongest and hardest amorphous material显示文摘Carbon is one of the most fascinating elements due to its structurally diverse allo tropic forms stemming from its bonding varieties(sp,sp^(2)and sp^(3)).Exploring new forms of carbon has been the eternal theme of scientific research.Herein,we report on amorphous(AM) carbon materials with a high fraction of sp^(3)bonding recovered from compression of fullerene C_(60) under high pressure and high temperature,previously unexplored.Analysis of photoluminescence and absorption spectra demonstrates that they are semiconducting with a bandgap range of 1.5-2.2 eV,comparable to that of widely used AM silicon.Comprehensive mechanical tests demonstrate that synthesized AM-Ⅲ carbon is the hardest and strongest AM material known to date,and can scratch diamond crystal and approach its strength.The produced AM carbon materials combine outstanding mechanical and electronic properties,and may potentially be used in photovoltaic applications that require ultrahigh strength and wear resistance. | Shuangshuang Zhang Zihe Li Kun Luo Julong He Yufei Gao Alexander V.Soldatov Vicente Benavides Kaiyuan Shi Anmin Nie Bin Zhang Wentao Hu Mengdong Ma Yong Liu Bin Wen Guoying Gao Bing Liu Yang Zhang Yu Shu Dongli Yu Xiang-Feng Zhou Zhisheng Zhao Bo Xu Lei Su Guoqiang Yang Olga P.Chernogorova Yongjun Tian | 2022 | National Science Review2022，9，1： | 2 |
| 8 | Quantum discord of thermal states of a spin chain with Calogero-Moser type interaction显示文摘In this paper,we have investigated the effect of Calogero-Moser type interaction on the quantum discord of thermal states of a spin chain.Our results imply that the quantum discord depends on the relative distance between the spins,the external magnetic field,and the temperature.By a comparison between the quantum discord and the entanglement of formation,the quantum discord is more robust than the entanglement of formation in the sense that the latter takes a zero value in a large range of the parameters,while the former takes a nonzero value. | MA XiaoSan QIAO Ying ZHAO GuangXing WANG AnMin | 2013 | Science China Chemistry2013，56，3： | 2 |
| 9 | TLR7/8 signalling affects X-sperm motility via the GSK3α/β-hexokinase pathway for the efficient production of sexed dairy goat embryos显示文摘Background:Goat milk is very similar to human milk in terms of its abundant nutrients and ease of digestion.To derive greater economic benefit,farmers require more female offspring(does);however,the buck-to-doe offspring sex ratio is approximately 50%.At present,artificial insemination after the separation of X/Y sperm using flow cytometry is the primary means of controlling the sex of livestock offspring.However,flow cytometry has not been successfully utilised for the separation of X/Y sperm aimed at sexing control in dairy goats.Results:In this study,a novel,simple goat sperm sexing technology that activates the toll-like receptor 7/8(TLR7/8),thereby inhibiting X-sperm motility,was investigated.Our results showed that the TLR7/8 coding goat Xchromosome was expressed in approximately 50%of round spermatids in the testis and sperm,as measured from cross-sections of the epididymis and ejaculate,respectively.Importantly,TLR7/8 was located at the tail of the Xsperm.Upon TLR7/8 activation,phosphorylated forms of glycogen synthase kinaseα/β(GSK3α/β)and nuclear factor kappa-B(NF-κB)were detected in the X-sperm,causing reduced mitochondrial activity,ATP levels,and sperm motility.High-motility Y-sperm segregated to the upper layer and the low-motility X-sperm,to the lower layer.Following in vitro fertilisation using the TLR7/8-activated sperm from the lower layer,80.52±6.75%of the embryos were XX females.The TLR7/8-activated sperm were subsequently used for in vivo embryo production via the superovulatory response;nine embryos were collected from the uterus of two does that conceived.Eight of these were XX embryos,and one was an XY embryo.Conclusions:Our study reveals a novel TLR7/8 signalling mechanism that affects X-sperm motility via the GSK3α/β-hexokinase pathway;this technique could be used to facilitate the efficient production of sexed dairy goat embryos. | Fa Ren Huaming Xi Yijie Ren Yu Li Fei Wen Ming Xian Mengjie Zhao Dawei Zhu Liqiang Wang Anmin Lei Jianhong Hu | 2022 | Journal of Animal Science and Biotechnology2022，13，2： | 2 |

| 13 | Covalent organic framework shows high isobutene adsorption selectivity from C_(4) hydrocarbons:Mechanism of interpenetration isomerism and pedal motion显示文摘Adsorption and separation of C_(4) hydrocarbons are crucial steps in petrochemical processes.Employment of porous materials for enhancing the separation efficiency have paid much attention.Covalent-organic frameworks of diamond-topology,dia-COFs,often exhibit unique structural properties such as interpenetration isomerism and pedal motion.Herein,in order to get a deep insight into the structure-performance correlation of such dia-COFs,a series of dia-COF materials have been proposed and theoretically investigated on the C_(4) separation.It is found that these dia-COFs display an excellent adsorption and separation property towards isobutene with respect to other C_(4) hydrocarbons(i.e.,1,3-butadiene,1-butene,2-cis-butene,2-trans-butene,isobutane and n-butane).What’s more,the correlation between the topology parameters and experimental synthesis feasibility has been established for COF-300(dia-cN),and the unreported COF-300(dia-c3) is predicted to be experimentally feasible synthesized.Our findings not only provide a deep insight into the mechanism of topology characteristics of dia-COFs on C_(4) adsorption and separation properties but also guide the design and synthesis of novel highly-effective porous materials. | Wei Chen Mian Li Wen-Li Peng Ling Huang Chao Zhao Dinesh Acharya Wentao Liu Anmin Zheng | 2022 | Green Energy & Environment2022，7，2： | 1 |

| 15 | Ruan's conjecture on singular symplectic flops of mixed type显示文摘In this paper,we study the global singular symplectic flops related to the following affine hypersurface with cyclic quotient singularities,Vr,b={(x,y,z,t)∈C4|xy-z2r+t2=0}/μr(a,-a,b,0),r 2,where b=1 appears in Mori’s minimal model program and b=1 is a new class of singularities in symplectic birational geometry.We prove that two symplectic 3-orbifolds which are singular flops to each other have isomorphic Ruan cohomology rings.The proof is based on the symplectic cutting argument and virtual localization technique. | CHEN BoHui LI AnMin LI XiaoBin ZHAO GuoSong | 2014 | Science China Mathematics2014，57，6： | 0 |
