| 1 | The Sequence of Magmatic-Tectonic Events and Orogenic Processes of the Yanshan Belt, North China显示文摘This paper emphasizes that the interactive constraints of geology and isotopic dating is the best approach to construct the geological event sequence, and has compiled 106 data of reasonable isotopic ages for the igneous rocks of the Yanshan belt. We propose a sequence of mgmatic-tectonic events in the Jurassic-Cretaceous Yanshan orogen of North China. Five orogenic episodes are divided, (1) pre-and initial orogenic episode (Early Jurassic); (2) early orogenic episode (Middle Jurassic); (3) peak orogenic episode (Late Jurassic); (4) late orogenic episode (early Early Cretaceous),and (5) post-orogenic episode. Each episode is a short cycle, all of the orogenic processes construct a longer cycle, and they, in general, followed a counter-clockwise (ccw) PTt path. Finally, it is suggested that the Yanshanian movement was so intensive that the magmatism and tectonic deformation had involved all the lithosphere thickness and the lateAchaean-formed cratonic lithosphere had been significantly reworked. | DENG Jinfu, SU Shangguo, MO Xuanxue, ZHAO Guochun, XIAO Qinghiu, JI Guangyi,QIU Ruizhao, ZHAO Hailing, LUO Zhaohua, WANG Yang and LIU Cui China University of Geosciences, Beijing 100083 and Key Laboratory of Lithospheric Tectonics and Lithoprobe Techniques, Ministry of Education of China | 2004 | Acta Geologica Sinica(English Edition)2004，78，1： | 35 |
| 2 | The coupling of dynamics and permeability in the hydrocarbon accumulation period controls the oil-bearing potential of low permeability reservoirs:a case study of the low permeability turbidite reservoirs in the middle part of the third member of Shahejie显示文摘The relationships between permeability and dynamics in hydrocarbon accumulation determine oilbearing potential(the potential oil charge) of low permeability reservoirs.The evolution of porosity and permeability of low permeability turbidite reservoirs of the middle part of the third member of the Shahejie Formation in the Dongying Sag has been investigated by detailed core descriptions,thin section analyses,fluid inclusion analyses,carbon and oxygen isotope analyses,mercury injection,porosity and permeability testing,and basin modeling.The cutoff values for the permeability of the reservoirs in the accumulation period were calculated after detailing the accumulation dynamics and reservoir pore structures,then the distribution pattern of the oil-bearing potential of reservoirs controlled by the matching relationship between dynamics and permeability during the accumulation period were summarized.On the basis of the observed diagenetic features and with regard to the paragenetic sequences,the reservoirs can be subdivided into four types of diagenetic fades.The reservoirs experienced two periods of hydrocarbon accumulation.In the early accumulation period,the reservoirs except for diagenetic fades A had middle to high permeability ranging from 10 × 10^(-3) μm^2 to4207 × 10^(-3) μm^2.In the later accumulation period,the reservoirs except for diagenetic fades C had low permeability ranging from 0.015 × 10^(-3)~ μm^2 to 62 × 10^(-3) μm^2.In the early accumulation period,the fluid pressure increased by the hydrocarbon generation was 1.4-11.3 MPa with an average value of 5.1 MPa.and a surplus pressure of1.8-12.6 MPa with an average value of 6.3 MPa.In the later accumulation period,the fluid pressure increased by the hydrocarbon generation process was 0.7-12.7 MPa with an average value of 5.36 MPa and a surplus pressure of1.3-16.2 MPa with an average value of 6.5 MPa.Even though different types of reservoirs exist,all can form hydrocarbon accumulations in the early accumulation period.Such types of reservoirs can form hydrocarbon accumulation with high accumulation dynamics:however,reservoirs with diagenetic facies A and diagenetic fades B do not develop accumulation conditions with low accumulation dynamics in the late accumulation period for very low permeability.At more than 3000 m burial depth,a larger proportion of turbidite reservoirs are oil charged due to the proximity to the source rock.Also at these depths,lenticular sand bodies can accumulate hydrocarbons.At shallower depths,only the reservoirs with oil-source fault development can accumulate hydrocarbons.For flat surfaces,hydrocarbons have always been accumulated in the reservoirs around the oil-source faults and areas near the center of subsags with high accumulation dynamics. | Tian Yang Ying-Chang Cao Yan-Zhong Wang Henrik Friis Beyene Girma Haile Ke-Lai Xi Hui-Na Zhang | 2016 | Petroleum Science2016，13，2： | 10 |
| 3 | On the Kinematic Characteristics and Dynamic Process of Boundary faults of the Nansha Ultra-crust Layer-Block显示文摘The Nansha ultra-crust layer-block is confined by ultra-crustal boundary faults of distinctive features, bordering the Kangtai-Shuangzi-Xiongnan extensional faulted zone on the north, the Baxian-Baram-Yoca-Cuyo nappe faulted zone on the south, the Wan’an-Natuna strike-slip tensional faulted zone on the west and the Mondoro-Panay strike-slip compressive faulted zone on the east. These faults take the top of the Nansha asthenosphere as their common detachmental surface. The Cenozoic dynamic process of the ultra-crust layer-block can be divided into four stages: K2-E21, during which the northern boundary faults extended, this ultra-crust layer-block was separated from the South China-Indosinian continental margin, the Palaeo-South China Sea subducted southwards and the Sibu accretion wedge was formed; E22-E31, during which the Southwest sub-sea basin extended and orogeny was active due to the collision of the Sibu accretion wedge; E32-N11, during which the central sub-sea basin extended, the Miri | LIU Hailing SUN Yan GUO Lingzhi SHU Liangshu YANG Shukang ZHOU Di ZHANG Yixiang | 1999 | Acta Geologica Sinica(English Edition)1999，73，4： | 9 |
| 4 | MiR156 regulates anthocyanin biosynthesis through SPL targets and other microRNAs in poplar显示文摘Anthocyanins biosynthesized from the flavonoid pathway are types of pigments that are involved in the protection of poplar from biotic and abiotic stresses.Previous researchers studying anthocyanin-related transcription factors and structural genes in poplar have made significant discoveries.However,little is known about the regulatory role of microRNAs in anthocyanin biosynthesis in poplar.Here,we overexpressed miR156 in poplar to study the comprehensive effects of the miR156-SPL module on the biosynthesis of anthocyanins.Small RNA sequencing analysis revealed 228 microRNAs differentially expressed in transgenic poplar plants with dramatically increased miR156 levels.Furthermore,integrated microRNAomic and transcriptomic analysis suggested that two microRNAs,miR160h,and miR858,have the potential to affect anthocyanin accumulation in poplar by regulating auxin response factors and MYB transcription factors,respectively.Additionally,the accumulation of miR160h and miR858 displayed a positive correlation with miR156 levels,suggesting a possible interaction between the miR156-SPL module and these microRNAs in poplar.Last,metabolomics analysis revealed that the levels of anthocyanins,flavones,and flavonols were substantially elevated in transgenic poplar plants overexpressing miR156 compared with the wild type,whereas the total lignin content was reduced in the transgenic plants.Taken together,our results indicate that miR156 can fine tune the anthocyanin biosynthetic pathway via multiple factors,including microRNAs,transcription factors,and the levels of structural genes,in poplar.This provides additional clues for understanding the complex regulatory network of anthocyanin biosynthesis in woody plants. | Yamei Wang Wenwen Liu Xinwei Wang Ruijuan Yang Zhenying Wu HanWang LeiWang Zhubing Hu Siyi Guo Hailing Zhang Jinxing Lin Chunxiang Fu | 2020 | Horticulture Research2020，7，1： | 9 |
| 5 | Study on the Behavior of Solar Array Deployment with Root Hinge Drive Assembly显示文摘In this paper, a method of using a root hinge drive assembly (RHDA) to control the solar array deployment is provided and a multi-DOF mechanism dynamic model of the system is established. In this way, the root hinge torque can be calculated iteratively. Then taking the predicted torque as a reference, a RHDA is designed for a large multiple-stage packaging and deployable solar array system. The control effect of the drive assembly is validated by ground tests. The test results indicate that the solar arrays can be deployed smoothly, and the deployment velocities are restricted by the drive assembly as expected. During the tests, the RHDA output speed and output torque are obtained. In order to examine the impact force when the yoke is lock-up with a hard stop, dynamics simulations are performed according to the actual behavior. The simulation result indicates that the designed RHDA reduces the impact force significantly and improves the lock-up reliability effectively. | DING Xilun LI Xin XU Kun YANG Qiaolong PU Hailing | 2012 | Chinese Journal of Aeronautics2012，25，2： | 6 |
| 6 | Effect of defect complex on magnetic properties of (Fe, Mn)-doped ZnO thin films显示文摘We have observed room temperature ferromagnetism in Mn-doped and (Fe, Mn)-codoped ZnO thin films grown under different oxygen partial pressures by pulsed laser deposition. The X-ray diffraction and optical transmission spectra studies demonstrate the natural incorporation of Fe and Mn cations into wurtzite ZnO lattices. The effects of transition metal doping and defects on the magnetic properties was investigated. It is found that room temperature ferromagnetism is sensitive to oxygen vacancy and Zn vacancy. The absence of ferromagnetism in pure ZnO films grown under different oxygen partial pressures reveals that the transition metal ions should also play an important role in inducing the ferromagnetism. | Yang, Hailing Xu, Xiaoguang Zhang, Guoqing Miao, Jun Zhang, Xin Wu, Shizhe Jiang, Yong | 2012 | Rare Metals2012，31，2： | 5 |
| 7 | Effects of Annealing on Microstructure, Mechanical and Electrical Properties of AlCrCuFeMnTi High Entropy Alloy显示文摘The multi-component AlCrCuFeMnTi high entropy alloy was prepared using a vacuum arc melting process. Serial annealing processes were subsequently performed at 590 ℃, 750 ℃, 955 ℃ and 1 100 ℃ respectively with a holding time of 4 h at each temperature. The effects of annealing on microstructure, mechanical and electrical properties of as-cast alloy were investigated by using differential thermal analysis(DTA), X-ray diffraction(XRD), scanning electron microscopy(SEM) and transmission electron microscopy(TEM). The experimental results show that two C14 hexagonal structures remain unchanged after annealing the as-cast AlCrCuFeMnTi alloy specimens being heated to 1 100 ℃. Both annealed and as-cast microstructures show typical cast-dendrite morphology and similar elemental segregation. The hardness of alloys declines as the annealing temperature increases while the strength of as-cast alloy improves obviously by the annealing treatment. The electrical conductivities of annealed and as-cast alloys are influenced by the distribution of interdendrite regions which is rich in Cu element. | NONG Zldsheng NONG Zldsheng ZHU Jingchuan YANG Xiawei YU Hailing LAI Zhonghong | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，6： | 5 |
| 8 | Enhancement of transfection efficiency for HeLa cells via incorporating arginine moiety into chitosan显示文摘Arginine-rich peptides have attracted considerable attention due to their distinct internalization mechanism. It was reported that arginine and guanidino moieties were able to translocate through cell membranes and played a critical role in the process of membrane permeation. In this work, arginine was conjugated to the backbone of chitosan to form a novel chitosan derivative, arginine modified chitosan (Arg-CS). Arg-CS/DNA complexes were prepared according to the method of coacervation process. The physicochemical properties of Arg-CS and Arg-CS/DNA complexes were characterized and the transfection activity and efficiency mediated by Arg-CS/DNA complexes were investigated taking HeLa cells as target cells. Arg-CS was characterized by FTIR and 13C NMR. Arg-CS/DNA polye- lectrolyte complexes were investigated by agarose gel retardation, dynamic light scattering (DLS) and atomic force microscopy (AFM). The results revealed that the Arg-CS/DNA complexes started to form at N/P ratio of 2:1, and the size of particles varied from 100 to 180 nm. The cytotoxicity of Arg-CS and their complexes with plasmid DNA were determined by MTT assay for HeLa cells, and the results suggested that Arg-CS/DNA complexes were slightly less toxic than Arg-CS. Moreover, the derivative alone and their complexes showed significantly lower toxicity than PEI and PEI/DNA complexes, respectively. Taking HeLa cells as target cells and using pGL3-control as reporter gene, the luciferase expression mediated by Arg-CS was greatly enhanced to about 100 folds compared with the luciferase expression mediated by chitosan at different pH media. These results suggest that Arg-CS is a promising candi- date as a safe and efficient vector for gene delivery and transfection. | ZHU DunWan ZHANG HaiLing BAI JinGen LIU WenGuang LENG XiGang SONG CunXian YANG Jian LI XiaoWei JIN Xu SONG LiPing LIU LanXia LI XiuLan ZHANG Yang YAO KangDe | 2007 | Chinese Science Bulletin2007，52，23： | 4 |
| 9 | Effect of annealing atmosphere on magnetic properties of pure ZnO and Na:ZnO films显示文摘Pure ZnO and Zn0.96Na0.04O films were grown on quartz substrates by sol-gel technology.The XRD analysis revealed that all thin films had hexagonal wurtzite structure and obvious c-axis preferred orientation.Ferromagnetism was precisely measured by an alternating gradient magnetometer (AGM).To explore the nature original ferromagnetism,the effect of annealing atmosphere on magnetic properties of the films was studied.Compared with pure ZnO,magnetic hysteresis loops showed that doping Na atoms enhanced saturation magnetism.The mag-netism of the films annealed in the air atmosphere was significantly better than that in the O2 atmosphere.The photoluminescence (PL) spec-trum analysis suggested that the ferromagnetism was due to the defects in the films. | Wu, Kai Xu, Xiaoguang Yang, Hailing Zhang, Jianli Miao, Jun Jiang, Yong | 2012 | Rare Metals2012，31，1： | 3 |
| 10 | Study on Connotations and Development Strategies of Creative Agriculture显示文摘Creative agriculture is a new agricultural type with originality as a key element, integrating agricultural production activities into creative activities such as culture and art, broadening functions of agriculture and improving added value of agricultural products. Creative agriculture is characterized by external economy, technology integration, art appreciation, high efficiency and value, and it is significant for promoting inheritance of traditional culture, optimal allocation and regeneration of resources, optimal distribution of elements, expansion of agricultural functions, construction of beautiful countryside, cultural construction of rural areas, transformation of agricultural and rural economic growth mode. With agricultural resources as the foundation, sightseeing and leisure agriculture as the breakthrough point, by means of science and technology, many regions in China have explored products of creative agriculture and presented several typical cases of creative agriculture. However, these projects are mostly restricted by problems such as poor development concept, lack of supportive policies, and ineffective industrial integration. Taking Zhejiang Province as an example, we proposed path choice, supportive system and relevant policy suggestions for the development of creative agriculture. | Liangshan YANG Hailing HE | 2013 | Asian Agricultural Research2013，5，4： | 2 |
| 11 | Enhanced catalysis of ultrasmall Au-MoS_2 clusters against reactive oxygen species for radiation protection显示文摘Ionizing radiation produces excessive reactive oxygen species(ROS) which impose detrimental effects on biological systems. Thus, it is important to explore clinically safe and efficacious radioprotection agents to scavenge ROS and reduce the risks of radiotherapy. Recently, emerging catalytic nanomaterials such as sulfide nanomaterials have shown capability of clearing ROS in vivo by unique electron transfers between atoms, but their catalytic activities are yet suboptimal. As such, there is an unmet need to improve catalytic properties for stronger antioxidant activities and radiation protection. Herein, we prepared ultrasmall Au-MoS_2 clusters(~2.5 nm) and they showed enhanced catalytic properties via gold intercalation facilitating increased active sites and synergistic effects. Electrocatalysis results revealed that the catalytic activity of Au-MoS_2 towards H2O_2 was superior to ultrasmall MoS_2 without Au. As a result, we found that improving the electrocatalytic property of Au-MoS_2 can effectively enhance corresponding antioxidant activities and radioprotection effects in vivo. In addition, Au-MoS_2 also showed significant radioprotection in vitro and dramatically reduced the excess of radiation-induced adverse ROS. It also rescued radiation-induced DNA damages and protected the bone marrow hematopoietic system from ionizing radiation. | Peixian Bian Jinxuan Zhang Junying Wang Jiang Yang Jingya Wang Haile Liu Yuanming Sun Meixian Li Xiao-Dong Zhang | 2018 | Science Bulletin2018，63，14： | 2 |
| 12 | UMSCs Attenuate LPS/D-GalN-induced Acute Liver Failure in Mice by Down-regulating the MyD88/NF-κB Pathway显示文摘Background and Aims:Acute liver failure(ALF)is an inflammatory process of acute liver cell injury.Mesenchymal stem cells(MSCs)are undifferentiated,primitive cells with antiinflammatory,anti-apoptotic,and multi-directional differentiation abilities.This study aimed to explore the therapeutic mechanism of umbilical cord(U)MSCs in ALF.Methods:Dgalactosamine(D-GalN)combined with lipopolysaccharide(LPS)was used to establish an ALF model.After model establishment,UMSCs were injected via the tail vein.After UMSC transplantation,the number of mouse deaths was monitored every 12 h.A fully automatic biochemical analyzer was used to detect changes in biochemical analysis.Pathological changes was observed by stained with hematoxylin and eosin.The expression of My D88 was detected by immunohistochemical analysis,quantitative reverse transcription,and western blotting.The expression of NF-κB was detected by quantitative reverse transcription,western blotting.The expression of Bcl-2,Bax were detected by quantitative reverse transcription,western blotting.The expression of TNF-α,IL-1β,IL-6 were detected by enzyme-linked immunosorbent assay.Results:The 48-h survival rate of the UMSC-treated group was significantly higher than that of the LPS/D-GalNexposed group.After 24 h of LPS/D-GalN exposure,UMSCs reduced serum alanine aminotransferase and aspartate aminotransferase levels and improved the liver structure.Western blot and real-time fluorescence quantitative nucleic acid amplification analyses showed that UMSCs decreased MyD88 expression,thereby inhibiting LPS/GalN-induced phosphorylation and degradation of inhibitor of nuclear factor(NF)-κB(IκB).Additionally,NF-κB p65 underwent nuclear translocation,inhibiting the production of the inflammatory factors interleukin(IL)-1β,IL-6 and tumor necrosis factor(TNF)-αand played a protective role in ALF by down-regulating the pro-apoptotic gene Bax and up-regulating the anti-apoptotic gene Bcl-2.In summary,these findings indicate that UMSCs play a protective role in LPS/GalN-induced acute liver injury via inhibition of the MyD88 pathway and subsequent inhibition of NF-κB-mediated cytokine production.Conclusions:Through the above mechanisms,UMSCs can effectively reduce LPS/D-GalN-induced ALF,reduce mouse mortality,and restore damaged liver function and damaged liver tissue. | Hailing Liao Siying Du Ting Jiang Mengyao Zheng Zhao Xiang Jinhui Yang | 2021 | Journal of Clinical and Translational Hepatology2021，9，5： | 2 |

| 15 | Ethacrynic acid targets GSTM1 to ameliorate obesity by promoting browning of white adipocytes显示文摘Dear Editor,Obesity is caused by an imbalance between energy intake and expenditure,and has become a global epidemic with over 650 million adults affected.Adipose tissues in mammals are composed of white adipose tissue(WAT)and classical brown adipose tissue(BAT),and their balance is highly related to the occurrence of obesity.The browning of white adipocytes results in“beige”or“brite”adipocytes,which appear functionally similar to classical brown adipocytes,and can be detected in WAT deposits of animals that have been exposed to cold or other inducers(Fu et al.,2015). | Zhaomeng Cui Yang Liu Wei Wan Yuyan Xu Yehui Hu Meng Ding Xin Dou Ruina Wang Hailing Li Yongmei Meng Wei Li Wei Jiang Zengxia Li Yiming Li Minjia Tan Dengke KMa Yu Ding Jun OLiu Cheng Luo Biao Yu Qiqun Tang Yongjun Dang | 2021 | Protein & Cell2021，12，6： | 1 |
| 16 | U-Pb Isotope Geochronology of Syntectonic Granites from Hainan Island,South China:Constraints on Tectonic Evolution of the Eastern Paleo-Tethys Ocean显示文摘Since the recognition of the Indosinian orogeny in northern Vietnam,Triassic orogens have been widely identified around the western and southwestern boundaries of the South China block.The paleo-Tethys sutures stretch from west to southeast,from Jinshajiang-Ailaoshan via NE Vietnam to Hainan Island;these sutures exhibit and develop voluminous Permian-early Triassic magmatism and numerous high-strain shear zones.As ophiolites related to the paleo-Tethys are lacking on Hainan Island,the eastward extension of the Indosinian orogeny and subduction and closure time of the paleo-Tethys Ocean on Hainan Island remain controversial.Here,an integrated kinematic and geochronological study has been conducted on two shear zones,called the Xiaomei and Mangsan shear zones.U-Pb zircon dating yields an age of early Triassic(252-251 Myr)for Xiaomei syntectonic granites which formed in the same tectonic setting and presented the similar nanoparticles to the Indosinian granites from Ailaoshan ductile shear zone,including the strawberry-like and flower-like nanoparticles.The NE-trending Mangsan shear zone represented by the gneissic granites with middle Permian ages(264-262 Myr)formed in the same tectonic setting as the Wuzhi-shan granites that were proposed as I-type granites.These middle Permian gneissic granites with arc affinity may represent an arc setting related to the NW subduction of the paleo-Tethys.The analyses reveal that granites with late Triassic ages(235-232 Myr)in the Xiaomei shear zone have the characteristics of A-type granites.The late Triassic extensional events on Hainan Island may be related to the subduction of the paleo-Pacific Plate beneath the East Asian continent. | ZHOU Yang YAN Yi LIU Hailing CAI Jianxin ZHOU Mengfei ZHANG Xinchang WANG Yin SHEN Baoyun | 2020 | Journal of Ocean University of China2020，19，6： | 1 |

| 18 | Risk Prevention and Control for Agricultural Non-Point Source Pollution Based on the Process of Pressure-Transformation-Absorption in Chongqing, China显示文摘According to China’s second national survey of pollution sources, the contribution of agricultural non-point sources(ANS) to water pollution is still high. Risk prevention and control are the main means to control costs and improve the efficiency of ANS, but most studies directly take pollution load as the risk standard, leading to a considerable misjudgment of the actual pollution risk. To objectively reflect the risk of agricultural non-point source pollution(ANSP) in Chongqing, China, we investigated the influences of initial source input, intermediate transformation, and terminal absorption of pollutants via literature research and the Delphi method and built a PTA(pressure kinetic energy, transformation kinetic energy, and absorption kinetic energy) model that covers 12 factors, with the support of geographical information system(GIS) technology. The terrain factor calculation results and the calculation results of other factors were optimized by Python tools to reduce human error and workload. Via centroid migration analysis and Kernel density analysis, the risk level, spatial aggregation degree, and key prevention and control regions could be accurately determined. There was a positive correlation between the water quality of the rivers in Chongqing and the risk assessment results of different periods, indirectly reflecting the reliability of the assessment results by the proposed model. There was an obvious tendency for the low-risk regions transforming into high-risk regions. The proportion of high-risk regions and extremely high-risk regions increased from 17.82% and 16.63%in 2000 to 18.10% and 16.76% in 2015, respectively. And the risk level in the main urban areas was significantly higher than that in the southeastern and northeastern areas of Chongqing. The centroids of all grades of risky areas presented a successive distribution from west to east, and the centroids of high-risk and extremely high-risk regions shifted eastward. From 2000 to 2015, the centroids of highrisk and extremely high-risk regions moved 4.63 km(1.68°) and 4.48 km(12.08°) east by north, respectively. The kernel density analysis results showed that the high-risk regions were mainly concentrated in the main urban areas and that the distribution of agglomeration areas overall displayed a transition trend from contiguous distribution to decentralized concentration. The risk levels of the regions with a high proportion of cultivated land and artificial surface were significantly increased, and the occupation of cultivated land in the process of urbanization promoted the movement of the centroids of high-risk and extremely high-risk regions. The identification of key areas for risk prevention and control provides data scientific basis for the development of prevention and control strategies. | ZHU Kangwen CHEN Yucheng ZHANG Sheng YANG Zhimin HUANG Lei LEI Bo XIONG Hailing WU Sheng LI Xixi | 2021 | Chinese Geographical Science2021，31，4： | 1 |

| 20 | Electronic structures of Heusler alloy Co_2FeAl_(1-x)Si_x surface显示文摘We have calculated the electronic structures of Co2FeAl1-xSix(101) surface using first-principles method based on the density functional theory. Because of the surface effect, the minority spin band gap at the Fermi level disappears at the surface of bulk Co2FeAl1-xSix. However, beneath the surface, the minority spin gap opens at the Fermi level, which indicates that the electronic structures of Co2FeAl1-xSix(101) become close to that of bulk phase. Accordingly, the Co2FeAl1-xSix(101) surface is a composite tri-layer structure that corresponds to the weakening of half-metallic property in Co2FeAl1-xSix films. Even though, the spin polarization of Co2FeAl1-xSix(101) surface is still larger than that of Co2FeAl or Co2FeSi materials, making Co2FeAl1-xSix a promising spintronics material. | Xu, Xiaoguang Zhang, Delin Wu, Yong Zhang, Xin Li, Xiaoqi Yang, Hailing Jiang, Yong | 2012 | Rare Metals2012，31，2： | 1 |
