| 1 | A New Titanosaurian Sauropod from Late Cretaceous of Nei Mongol, China显示文摘A specimen collected from the Upper Cretaceous Erlian Formation of Nei Mongol (Inner Mongolia), China, represents a new genus and species of titanosaurian sauropod. The new taxon is named and described on the basis of the holotype and the only known specimen, which comprises several dorsal, sacral, and caudal vertebrae, several dorsal ribs, one anterior chevron, and much of the pelvis. Diagnostic features of the new species include a thick ridge extending down from the postzygapophysis on the lateral surface of the neural arch of the posterior dorsal vertebrae, a transversely oriented accessory lamina present between the anterior centroparapophyseal limina and the lateral centraprezygapophyseal lamina of the posterior dorsal vertebrae, long, anteroventrally directed caudal rib that bears two distinctive fossae on its posterior margin on the anterior caudal vertebrae and a prominent vertical ridge above the pubic peduncle on the medial surface of the ilium, among others. The ilium is pneumatic, a feature not common among non-avian dinosaurs. The new taxon has an unusual combination of primitive and derived character states. Preliminary character analysis shows a complex character distribution within the Titanosauriformes. Recent titanosauriform discoveries suggest that a significant radiation occurred in Asia early in the titanosauriform evolution. | XU Xing ZHANG Xiaohong TAN Qingwei ZHAO Xijin TAN Lin | 2006 | Acta Geologica Sinica(English Edition)2006，80，1： | 7 |

| 4 | The mechanisms of grain growth of Mg alloys:A review显示文摘Grain growth directly influences the plasticity and strength of Mg alloys.As the grain size decreases from the microscale to the nanoscale,the plasticity of Mg alloys continually increases,whereas the strength first increases and later decreases.These trends are observed because the plastic deformation mechanism changes from dislocation–twinning dominance to grain boundary dominance.In this study,the factors influencing grain growth,such as the temperature of plastic deformation/annealing,second-phase particles and solute atoms,are examined to aid effective control of the grain size.Additionally,the mechanisms of grain growth,typically induced by strain and thermal activation,are clarified.Strain-induced grain boundary migration is attributable to the difference in the strain energy stored in adjacent grains with high-density dislocations.Heat-induced grain boundary migration is driven by the difference in the energy of the grain boundary/subgrain boundary and boundary curvature.Abnormal grain growth can be induced by anisotropy of the strain energy,anisotropy of the grain boundary mobility,depinning of the second phase and high misorientation gradient. | Qinghua Chen Ruinan Chen Jian Su Qingsong He Bin Tan Chao Xu Xu Huang Qingwei Dai Jian Lu | 2022 | Journal of Magnesium and Alloys2022，10，9： | 1 |
| 5 | A Spiral Graphene Framework Containing Highly Ordered Graphene Microtubes for Polymer Composites with Superior Through-Plane Thermal Conductivity显示文摘As the power density of electronic devices increases,there has been an urgent demand to develop highly conductive polymer composites to address the accompanying thermal management issues.Due to the ultra-high intrinsic thermal conductivity,graphene is considered a very promising filler to improve the thermal conductivity of polymers.However,graphene-based polymer composites prepared by the conventional mixing method generally have limited thermal conductivity,even under high graphene loading,due to the failure to construct efficient heat transfer pathways in the polymer matrix.Here,a spiral graphene framework(SGF)containing continuous and highly ordered graphene microtubes was developed based on a modified CVD method.After embedding into the epoxy(EP)matrix,the graphene microtubes can act as efficient heat pathways,endowing the SGF/EP composites with a high through-plane thermal conductivity of 1.35 W·m^(-1)·K^(-1) at an ultralow graphene loading of 0.86 wt%.This result gives a thermal conductivity enhancement per 1 wt%filler loading of 710%,significantly outperforming various graphene structures as fillers.In addition,we demonstrated the practical application of the SGF/EP composite as a thermal interface material for efficient thermal man-agement of the light-emitting diode(LED). | Jinrui Gong Xue Tan Qilong Yuan Zhiduo Liu Junfeng Ying Le Lv Qingwei Yan Wubo Chu Chen Xue Jinhong Yu Kazuhito Nishimura Nan Jiang Cheng-Te Lin Wen Dai | 2022 | Chinese Journal of Chemistry2022，40，3： | 0 |
| 6 | A large-sized basal ankylopollexian from East Asia, shedding light on early biogeographic history of Iguanodontia显示文摘A presumably mostly quadrupedal ankylopollexian iguanodontian, Bayannurosaurus perfectus gen. et sp.nov., is reported here, and is represented by an excellently well-preserved skeleton from the Lower Cretaceous Bayingebi Formation of Inner Mongolia, China. The diagnosis of the taxon includes several autapomorphies, notably a dorsally directed, strap-like posterodorsal process of the jugal and a horizontally oriented preacetabular process of the ilium. The nearly complete caudal series retains eight posterior-most caudals with procoelous, trapezoidal centra in dorsal view, and the last three caudals are fully fused. The discovery of B. perfectus opens a critical new window on the early evolution and intercontinental dispersal of Iguanodontia. The skeleton displays a transitional morphology between nonhadrosauriform ankylopollexians and Hadrosauriformes. A phylogenetic analysis indicates that Bayannurosaurus is positioned higher on the tree than Hypselospinus, but below Ouranosaurus just outside of Hadrosauriformes. The tree topology of Iguanodontia with temporal and spatial constraints reveals a possible biogeographic scenario supported by the statistical dispersal-vicariance analysis: around the J/K boundary, non-hadrosauriform ankylopollexians experienced multiple dispersal events from Europe to Asia, accompanying the coeval fall of the global sea level. | Xing Xu Qingwei Tan Yilong Gao Zhiqiang Bao Zhigang Yin Bin Guo Junyou Wang Lin Tan Yuguang Zhang Hai Xing | 2018 | Science Bulletin2018，63，9： | 0 |

| 8 | Preparation and Characterization of Glass-Ceramic Basalt Fiber显示文摘Basalt fiber(BF)is widely applied in the construction industry to improve the mechanical properties of construction materials.Recent studies show that BF has the potential to further enhance its performance via a crystallization approach.In this work,the glass-ceramic basalt fibers(GCBFs)were prepared through nucleation and crystallization treatments according to the crystallization kinetics calculations.Results from XRD and SEM show that GCBFs have main crystalline phases of Diopside and Augite reach crystallinity of around 46%±10%.In particular,the GCBFs sample with the largest mean crystal size maintains the lowest tensile strength of~197 MPa(compared with the pristine BFs of~737 MPa).Moreover,the weight loss and ion dissolution of GCBFs were explored in seawater environments and it was investigated that,GCBFs have better anti-seawater corrosion than the pristine BFs and have the potential to apply in the marine industry. | Lida Luo Tan Yan Jin Liu Linfeng Ding Qingwei Wang Wan Jiang | 2022 | Journal of Harbin Institute of Technology(New Series)2022，29，6： | 0 |

| 11 | 6-6 Nb/Cu SRF Cavity R&D Activity at IMP显示文摘SRF cavities are operated at Meissner state,which al-lows the electro-magnetic wave only interacts with the very surface of the cavity.The penetration depth of Nb at 4.2 is^100 nm,which means more than 99%of the expensive SRF grade Nb used on the SRF cavity is not involved in the interaction with the E-M wave.Fig.1 shows the schematics diagram of the interac-tion between magnetic field and a Nb coated Cu cavity.With a Nb film thicker than 3λ,the copper hide behind wouldn't be able to see the E-M wave nor generate RF dissipation. | Tan Teng Pan Feng Huang Shichun Zhang Cong Chu Qingwei He Yuan Zhao Hongwei | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
