| 1 | Short-range ordering and its effects on mechanical properties of high-entropy alloys显示文摘In this letter,we briefly summarize experimental and theoretical findings of fo rmation and characterization of short-range orderings(SROs)as well as their effects on the defo rmation behavior of high-entropy alloys(HEAs).We show that existence of SROs is a common yet key structural feature of HEAs,and tuning the degree of SROs is an effective way for optimizing mechanical properties of HEAs.In additional,the challenges concerning about formation mechanism and characterization of SROs in HEAs are discussed,and future research activities in this regard are also proposed. | Yuan Wu Fei Zhang Xiaoyuan Yuan Hailong Huang Xiaocan Wen Yihan Wang Mengyuan Zhang Honghui Wu Xiongjun Liu Hui Wang Suihe Jiang Zhaoping Lu | 2021 | Journal of Materials Science & Technology2021，，3： | 8 |

| 3 | Nightside field-aligned current during the April 6,2000 superstorm显示文摘Using the east-west geomagnetic disturbance fields observed from stations at mid-latitudes,we investigate the characteristics of field-aligned currents on the nightside during the April 6,2000 superstorm.The results indicate that there is an eastward disturbance on the nightside of Northern Hemisphere during the main phase of magnetic storm,while the interplanetary magnetic field(IMF)is continued southward.The positive disturbances in the postmidnight are larger than that in the premidnight.This suggests that upward field-aligned currents develop on the nightside,when the IMF is directed southward.The peak of upward fieldaligned currents is located in postmidnight,and it will be more obvious at substorm expansion.We get the conclusion that both partial ring current and region-2 field-aligned current shift to dusk sector.The upward region-2 current is decreased at substorm onset,and intensified after it.We also investigate the relationship between the upward field-aligned currents on the nightside and the auroral electrojets at high latitudes.It shows a good correspondence between region-2 current and the westward electrojet in the postmidnight.We suppose that they are both associated with the convection electric field. | WANG Yuan HONG MingHua CHEN GengXiong XU WenYao DU AiMin ZHAO XuDong LIU XiaoCan LUO Hao | 2010 | Chinese Science Bulletin2010，55，20： | 3 |
| 4 | Ground magnetic characteristics of the storm-time ring current Asymmetry显示文摘Using the minute data of the H component of geomagnetic field from the 20°E magnetic meridian chain and the 30°N magnetic latitudinal chain, the temporal evolution characteristics of the equatorial ring current during the storm on November 7-10, 2004 are studied. It is indicated that the UT-MLT and UT-MLAT graphics extremely exhibit the local time distribution, latitudinal variation and temporal evo- lution of the H component. The results show: (1) The UT-MLT contour clearly shows the increasing of the H component mostly around noon during the initial phase, representing the geomagnetic effect from the magnetopause current system. During the main phase, most negative values of the H com- ponent appear around the dusk-side, indicating the dawn-dusk asymmetric distribution of the ring cur- rent. (2) The contour of UT-MLAT suggests the latitudinal variation of the H component decreasing with the enhancement of the latitudes during geomagnetic storm, which is in good agreement with the Dst index. The latitudinal variations provide a new sight for describing the temporal characteristics of the intensity of the storm-time ring current. (3) Both the contours of UT-MLT and UT-MLAT are useful to monitor the space-time distribution of the equatorial ring current. | WU YingYan XU WenYao CHEN GengXiong CHEN Bo LIU XiaoCan | 2008 | Science China Earth Sciences2008，51，5： | 3 |
| 5 | Comparing the diurnal variations in the SuperMAG auroral electrojet indices SML and SMU显示文摘Diurnal variations of the SuperMAG auroral electrojet indices(SML and SMU)were examined for the period of 1980–2010,and the differences between SML and SMU were especially analyzed.The diurnal variation of SML with a maximum at around 1100 UT has a prenoonpostnoon asymmetry.At solstices,the diurnal variation of SML is much stronger than that at equinoxes.For the SMU,two maxima are recorded in the diurnal variation with the bigger one at 1700 UT and the smaller one at 0400 UT.The seasonal variations are not obvious in the UT variation characteristics of SMU although the intensity of SMU is changed remarkably season by season.For both SML and SMU,the contributing stations are located at higher geomagnetic latitude around 1600 UT and at lower geomagnetic latitude around 0400 UT.These results indicate that:(1)the SML is mostly controlled by the convection electric field.Its diurnal variation is mainly correlated with the equinoctial and R-M hypothesis;(2)the SMU is largely controlled by the ionospheric conductance.Its diurnal variation is tightly correlated with the solar radiation. | Yuan Wang Aimin Du Gengxiong Chen Xin Cao Ying Zhang Min Li Xiaocan Liu Jianpeng Guo | 2014 | Chinese Science Bulletin2014，59，29： | 2 |
| 6 | Latitudinal shift and tilt of the ring current during magnetic storms显示文摘The equatorial ring current (ERC) theory suggested that the distribution of global disturbed horizontal geomagnetic field only depends on the cosine of station’s latitude. However,we always observe a lar-ger ΔH at higher latitude stations than lower ones,implying that the ERC could tilt or/and shift with respect to the equatorial plane during intense storms. In this paper,we analyze 11 intense magnetic storms from 2000 to 2004,and introduce two configurational factors to characterize the topology of storm time ring current. The results show that ERC has occasionally deviated off equatorial plane with both tilt angle δt≈13°―25° and latitude shift δs≈0°―21.8°. The ground disturbed field distribution should be improved as ΔHk = ΔHmaxcos(k-δ ),which agree well with the geomagnetic observations. | CHEN BO XU WenYao CHEN GengXiong DU AiMin WU YingYan LIU XiaoCan | 2009 | Chinese Science Bulletin2009，54，1： | 1 |

| 9 | Alternative Splicing of OsCYL4 Controls Drought Resistance via Regulating Water Loss and Reactive Oxygen Species-Scavenging in Rice显示文摘A rice cyclase gene,OsCYL4b,identified as an alternative splice variant of the cyclase gene OsCYL4a,is involved in the regulation of drought stress and oxidative response.Compared with OsCYL4a,OsCYL4b lacks the second exon,which is located in the conserved motif 3,and may be a functionally important site.Our results suggested that OsCYL4b was responsive to multiple abiotic stresses,and was localized to both the cytoplasm and plasma membrane.The overexpression of OsCYL4b resulted in significantly enhanced drought and osmotic stress tolerance,reduced water loss,and increased abscisic acid(ABA)content compared with the wild type(WT). | SHA Gan SHEN Xin WU Zini XU Xiaocan XU Xin TAN Yanping LIU Xinqiong TANG Xianyin WANG Chuntai QIN Yonghua | 2024 | Rice science2024，31，1： | 0 |
| 10 | Influence of doping nitrogen on the catalytic performance of carbon nanotubes encapsulating cobalt for selective oxidation of arylalkanes显示文摘Efficient selective oxidation of hydrocarbons to corresponding ketones has been a significant but challenging work in the past decades.Here,a nitrogen-doped bamboo-like carbon nanotubes encapsulating cobalt catalyst(NCNTs-X)using citric acid,melamine and CoCl_(2)·6H_(2)O as precursors was synthesized by a simple pyrolysis method.A series of characterization techniques were employed to investigate the physicochemical properties of samples.And the results show that the as-prepared catalysts achieve a high catalytic performance for selective ethylbenzene oxidation(78.3% ethylbenzene conversion)using molecular oxygen as oxidant,especially giving a high selectivity(93.8% selectivity to acetophenone).According to the investigation of the structure-activity relationship of the catalysts,it can be deduced that the Co-N_(x) sites have an obvious positive effect on catalytic performance thanks to the synergistic effect between metallic cobalt and pyridinic N. | Ganghua Xiang Xiaocan Wang Lushuang Zhang Zhigang Liu | 2021 | Particuology2021，19，5： | 0 |

| 12 | Geochronology,Geochemistry,Fluid Inclusion and C,O Isotope Compositions of Calcite Veins in the Paleogene of the Jiangling Basin,South China:Implications for Fluid Evolution and Brine Potash Mineralization显示文摘Deep-seated potassium-rich brines were identified in the Jiangling Basin,South China.Although magmatichydrothermal sources have been proposed,the relationship between brine-type potash mineralization and volcanism remains unclear.In this study,U-Pb geochronology,geochemistry,fluid inclusion and C-O isotopic compositions of hydrothermal vein minerals in the Jiangling Basin are examined.Laser ablation U-Pb dating of calcite veins indicates that the ages are slightly younger than the formation age of the Balingshan basalt.Fluid inclusions in hydrothermal minerals show medium–low homogenization temperatures(160–220℃)and low salinities(0.14 to 4.9 wt%NaCl eqv.)and densities(0.882–0.944 g/cm^(3)).The liquid compositions of fluid inclusions in calcite veins from sedimentary strata have higher contents of potassium,compared with those from basalt.The coupled negativeδ^(13)CPDB(-10.3‰to-8.0‰)and positiveδ^(18)OSMOW(17.4‰to 20.7‰)values imply that calcite precipitation resulted from CO_(2)degassing of the basaltic magmatic fluids,as indicated by the gas composition of these inclusions in hydrothermal minerals.Rare earth element patterns indicate that water-rock interaction between hydrothermal fluids and sedimentary wall rocks contributed to the calcite precipitation in sedimentary strata.It is proposed that high-temperature water-rock interaction between magmatic fluids and sedimentary strata resulted in the potassium enrichment in fluids,interpreted as one of the sources of potassium-rich brines in the Jiangling Basin. | YU Xiaocan WANG Chunlian LIU Chenglin WANG Jiuyi SHEN Lijian | 2023 | Acta Geologica Sinica(English Edition)2023，97，2： | 0 |
| 13 | Enhanced plastic deformation capacity in hexagonal-close-packed medium entropy alloys via facilitating cross slip显示文摘Alloys with a hexagonal close-packed(HCP)lattice often suffer from intrinsic brittleness due to their in-sufficient number of slip systems,which limits their practical uses.In this paper,nevertheless,we show that remarkably tensile ductility in HCP Hf-Zr-Ti medium entropy alloys(MEAs)was achieved,particu-larly in the MEAs with a higher content of Hf.Both first-principles calculation and experimental analyses reveal that addition of Hf increases basal I2 stacking fault energy and decreases prismatic stacking fault energy in these HCP MEAs,which promotes the source of pyramidal dislocations due to the facilitated cross slips of basal dislocations and eventually give rise to the observed large tensile ductility.Our current findings not only shed new insights into understanding deformation of HCP alloys,but also provide a basis for controlling alloying effects for developing novel HCP complex alloys with optimized properties. | Xiaocan Wen Hailong Huang Honghui Wu Meisa Zhou Yeqiang Bu Xiaoyuan Yuan Suihe Jiang Hui Wang Xiongjun Liu Hongtao Wang Jiabin Liu Yuan Wu Zhaoping Lu | 2023 | Journal of Materials Science & Technology2023，，3： | 0 |
| 14 | Computer-designed orthogonal RNA aptamers programmed to recognize Ebola virus glycoproteins显示文摘Ebola virus (EBOV), a member of the filovirus family, is an enveloped negative-sense RNA virus that causes lethal infections in humans and primates. Thousands of people have died from the Ebola virus disease (EVD) in West Africa, and no specific antiviral medication and treatment have been approved for EVD. Although the development of an EBOV vaccine is promising, immunity to any vaccine is not immediate. Here, we computationally analysed the structure of EBOV glycoprotein GP2 (GP2EBOV) and designed RNA aptamers that recognize and inhibit it. The aptamers specifically bind to conserved arginine residues (Arg587 and Arg596) located in the C-terminal coiled-coil region of GP2EBOV. Molecular docking of the synthetic RNA aptamers with the ectodomain of GP2EBOV revealed that the optimized orthogonal RNA aptamers have strong binding affinities with the coiled-coil region of GP2EBOV. The characterized RNA aptamers may facilitate strategies to block replication of EBOV and related Filoviruses, and thus may serve as important antivirals to reduce mortality associated with these infections. | Teng Yue Liu Shuxia Yang Shan Guo Xiaocan Zhang Yanwen Song Yajun Cui Yujun | 2019 | Biosafety and Health2019，1，2： | 0 |
