| 1 | Petrogenesis of Paleoproterozoic Luyashan charnockitic rocks in Shanxi Province: Constraints from Geochemistry and Nd isotope显示文摘Luyashan charnockite pluton 主要由二长岩, adamellite , charnockite 和 syenogranite 组成,它被 TiO 2, P 2 O 5, K 2 O , Zr , Nb , Y , Pb , La , Ce , Ba 和更高的 K 2 O/Na 2 MgO , CaO , Mg #, Th , U 和更低的 Sr 的 O 和弄空 Ba 和 Rb Ba 。在 Zr, Nb, Ce 和 SiO 2 之间的否定关联从我类型花岗石是不同的。同位素地 Luyashan charnockite plutons 在 Nd 同位素是相对一致的,显示起始的 εNd(t)( 到 -6.97) 和 Nd 的 -5.93 弄空披风模型年龄(到 2.78 Ga 的 2.67 Ga ) 。这些特征显示那 Luyashan charnockitic 岩浆从先存在导出晚太古代的外壳的来源并且与公司 2-rich 液体的在特别高的温度下面的可能的 mafic granulites 的部分融化。石榴石在部分融化期间是一个主要剩余阶段。原来的干燥 charnockitic 岩浆在早结晶化期间经历了辉石,斜长石,磷灰石,和钛铁矿的水晶分别。geochemical 证据建议 Luyashan charnockitic 岩浆可能在碰撞以后的热松驰被产生并且高举在主要碰撞以后的构造背景(∼

| 2 | Effects of thermal and electrical histories on structure and dielectric behaviors of(Li_(0.5)Nd_(0.5))^(2+)-modified(Bi_(0.5)Na_(0.5))TiO_(3)-BaTiO_(3) ceramics显示文摘The effect of thermal and electrical histories on structure and dielectric behaviors is studied using 0.95(Bi_(0.5)Na_(0.5))_(0.97)(Li_(0.5)Nd_(0.5))_(0.03)TiO_(3)-0.05BaTiO_(3)(abbreviated as BNTLN0.03-BT5)ceramic as a selected system.Subtle structure change caused by annealing treatment,and pronounced phase transition and domain switching by electrical poling,are observed to occur,respectively.The dielectric constant and its strong frequency dispersion in unpoled samples decrease evidently by electrical poling due to electric field-induced ordered domain.The high temperature Maxwell-Wagner relaxor behavior vanishes by annealing treatment due to the loss of electrical inhomogeneity with interface charging effects.Piezoelectric properties are improved evidently by annealing treatment at 900℃,implying a new appropriate method to improve piezoelectric properties. | Jiwen Xu Qingning Li Ling Yang Weidong Zeng Changrong Zhou Changlai Yuan Guohua Chen Guanghui Rao | 2017 | Journal of Materiomics2017,3,2: | 2 |
| 3 | Synthesis and High Electrocatalytic Performance of Hexagram Shaped Gold Particles Having an Open Surface Structure with Kinks显示文摘塑造的金粒子和他们的类似物与性变态由高索引方面围住的六芒星形被与维生素酸(AA ) 减少 HAuCl4 面对成功地综合了 poly (diallyldimethylammonium 氯化物) 在房间温度。由使用电子显微镜学,塑造的 Au 粒子被发现是的六芒星形的表面 { 541 } 飞机,它包含高密度的步和性变态。另外,它被发现那六角形像盾并且在产品在场的其它种粒子是塑造的 Au 粒子组织的六芒星形的类似物,在那,他们有一样的表面结构。以便证实所有准备粒子的表面结构,表面结构 Pb 的敏感 underpotential 免职被执行,并且周期的 voltammetric 侧面根据求婚 { 541 } 表面。最后, Au 六芒星形的结构性质关系被作为探查反应采用 AA 的 electrocatalytic 氧化试验性地分析。金立方体与的 electrocatalytic 反应低索引 { 100 } 方面和金 trioctahedra 与 { 221 } 方面作为参考书被学习。试验性的结果证明六芒星形塑造了 Au 粒子和他们的类似物与暴露 { 541 } 方面在三种金粒子之中举办最高催化的活动,由于纽结原子的高密度。这研究应该激发我们进一步为高索引表面围住的另外的明确的多面的金属 nanocrystals 的准备探索方法。 | Qingning Jiang Zhiyuan Jiang Lei Zhang Haixin Lin Ning Yang Huan Li Deyu Liu Zhaoxiong Xie Zhongqun Tian | 2011 | Nano Research2011,4,6: | 2 |
| 4 | Topological Shape Changes Weaken the Innate Defensive Response to Visual Threat in Mice显示文摘Understanding the primitives of visual perception is a fundamental question in the study of vision.T o address this question,a theory of topology-based functional hierarchy in visual perception has been proposed[1,2].This theory suggests that the extraction of topological properties(TPs)serves as the starting point of object perception.The T P of a figure is the holistic identity which remains constant across various smooth shape-changing transformations of an image[2]. | Yan Huang Lei Li Kun Dong Hongsi Tang Qingning Yang Xianglian Jia Yundan Liao Wenbo Wang Zhen Ren Lin Chen Liping Wang | 2020 | Neuroscience Bulletin2020,36,4: | 2 |

| 6 | Structural basis of signaling regulation of the human melanocortin-2 receptor by MRAP1显示文摘G protein-coupled receptors(GPCRs)are regulated by various downstream proteins,of which the melanocortin receptor accessory protein 1(MRAP1)is closely involved in the regulation of melanocortin receptor 2(MC2R).Assisted by MRAP1,MC2R responds to adrenocorticotropic hormone(ACTH)and stimulates glucocorticoid biogenesis and cortisol secretion.MC2R activation plays an essential role in the hypothalamic-pituitary-adrenal(HPA)axis that regulates stress response,while its dysfunction causes glucocorticoid insufficiency-or cortisol excess-associated disorders.Here,we present a cryo-electron microscopy(cryo-EM)structure of the ACTH-bound MC2R–G_(s)–MRAP1 complex.Our structure,together with mutagenesis analysis,reveals a unique sharp kink at the extracellular region of MRAP1 and the‘seat-belt’effect of MRAP1 on stabilizing ACTH binding and MC2R activation.Mechanisms of ACTH recognition by MC2R and receptor activation are also demonstrated.These findings deepen our understanding of GPCR regulation by accessory proteins and provide valuable insights into the ab initio design of therapeutic agents targeting MC2R. | Ping Luo Wenbo Feng Shanshan Ma Antao Dai Kai Wu Xianyue Chen Qingning Yuan Xiaoqing Cai Dehua Yang Ming-Wei Wang H.Eric Xu Yi Jiang | 2023 | Cell Research2023,33,1: | 0 |
