| 2 | A first-principles study of helium diffusion in quartz and coesite under high pressure up to 12GPa显示文摘Helium diffusion in mantle minerals is crucial for understanding mantle structure and the dynamic processes of Earth's degassing.In this paper,we report helium incorporation and the mechanism of its diffusion in perfect crystals of quartz and coesite.The diffusion pathways,activation energies(Ea),and frequency factors of helium under ambient and high pressure conditions were calculated using Density Functional Theory(DFT)and the climbing image nudged elastic band(CI-NEB)method.The calculated diffusive coefficients of He in the quartz in different orientations are:D[100]=1.24×10^(−6)exp.(−26.83 kJ/mol/RT)m^(2)/s D[010]=1.11×10^(−6)exp.(−31.60 kJ/mol/RT)m^(2)/s.and in the coesite:D[100]=3.00×10^(−7)exp.(−33.79 kJ/mol/RT)m^(2)/s D[001]=2.21×10^(−6)exp.(−18.33 kJ/mol/RT)m^(2)/s.The calculated results indicate that diffusivity of helium is anisotropic in both quartz and coesite and that the degree of anisotropy is much more pronounced in coesite.Helium diffusion behavior in coesite under high pressures was investigated.The activation energies increased with pressure:Ea[100]increased from 33.79 kJ/mol to 58.36 kJ/mol,and Ea[001]increased from 18.33 kJ/mol to 48.87 kJ/mol as pressure increased from0 GPa to 12 GPa.Our calculations showed that helium is not be quantitatively retained in silica at typical surface temperatures on Earth,which is consistent with the findings from previous studies.These results have implications for discussion of the Earth's mantle evolution and for recognition thermal histories of ultra-high pressure(UHP)metamorphic terranes. | Hong Liu Lingling Wang Shuchen Li Yaochun Yang Hua Tian Fengxia Sun Chaowen Xu Lei Liu Yi Li Yueju Cui Ying Li Jijun Zhao | 2021 | Geoscience Frontiers2021，12，2： | 1 |
| 3 | Enhanced thermoelectric performance and atomic-resolution interfacial structures in BiSbTe thermo-electro-magnetic nanocomposites incorporating magnetocaloric LaFeSi nanoparticles显示文摘Incorporating magnetic nanoparticles in thermoelectric(TE)materials introduce magnetic interfaces with additional electron and phonon scattering mechanism for high TE performance.However,the influence of heterogeneous interfaces between magnetic nanoparticles and TE matrix on electronic and thermal transport remains elusive in the thermo-electric-magnetic nanocomposites.Here,using p-type TE material Bi_(0.3)Sb_(1.7)Te_(3)(BST)as matrix and magnetocaloric(MC)material La(Fe_(0.92)Co_(0.08))_(11.9)Si_(1.1)(LFS)nanoparticles as a second phase,TE/MC nanocomposites xLFS/BST(x=0.1%,0.2%,0.3% and 0.4%)were synthesized using spark plasma sintering method.The atomic-resolution interfacial structures demonstrate that Te vacancies originating from LFS-BST interfacial reaction decreases the hole concentration of the LFS/BST nanocomposites and enhances the Seebeck coefficient.The LFS/BST nanocomposites exhibit lower thermal conductivity due to enhanced phonon scattering by interfaces and defects.All the nanocomposites have higher ZT than BST matrix,with 0.2% LFS/BST nanocomposite achieving highest ZT=1.11 at 380 K.At working current 1.4 A,the device fabricated using 0.2% LFS/BST nanocomposite achieves maximal cooling temperature 4.9 K,which is 58% higher than the matrix.Moreover,the MC properties are retained in all the nanocomposites,which make them a promising candidate to achieve high TE performance and dual TE/MC properties for future applications. | Lin Xing Wenjun Cui Xiahan Sang Fengxia Hu Ping Wei Wanting Zhu Xiaolei Nie Qingjie Zhang Wenyu Zhao | 2021 | Journal of Materiomics2021，7，5： | 1 |

| 5 | Severity stratification of aplastic anemia显示文摘To the editor:A scoring system for stratifying the severity of aplastic anemia (AA) is proposed and provides physicians with a useful tool to initiate immunosuppressive therapy timely and to improve response rate in patients with non-severe AA (NSAA).A total of 260 patients with newly diagnosed AA were enrolled into the study at Weifang People's Hospital between 2003 and 2012.1,2A correlation analysis was made between absolute neutrophil count (ANC),blood platelet count (BPC),reticulocyte count (Ret),hemoglobin,serum ferritin (SF),CD34+ cell and marrow cellularity. | Ren Cuiai Li Yanxiang Cui Jingying Liu Fengxia Sheng Zhixin Xu Wenjun Zhang Maohong | 2014 | Chinese Medical Journal2014，，16： | 0 |
| 6 | Two-dimensional Electrophoresis Analysis of Proteins Extracted from Alexandrium sp. LC3显示文摘Two-dimensional electrophoresis(2-DE) of protein extracted and purified from Alexandrium sp. LC3 was conducted. In the SDS-PAGE study, the relative molecular weights of the proteins were mainly in the range of 14 kDa?31 kDa and 43 kDa?66 kDa, and more proteins were detected between 14 kDa and 31 kDa. With the improved protein preparation, the two-dimensional electrophoresis patterns indicated that the relative molecular weights of the proteins were between 14 kDa and 100 kDa, and most of them ranged from 14 kDa to 31 kDa. This was consistent with the result of the SDS-PAGE analysis. The isoelectric points were found to lie between 3.0 and 8.0, and most of them were in the range of 3.0?6.0. Better separation effect was acquired with pre-prepared immobilized gradient (IPG) strip (pH 3?5.6), and about 320 protein spots could be visualized on the 2-DE map by staining. Within pH 3?10 and pH 3?5.6 strips, the protein samples of Alexandrium sp. LC3 could be separated well. | LI Hao MIAO Jinlai CUI Fengxia LI Guangyou | 2007 | Journal of Ocean University of China2007，6，4： | 0 |
