| 1 | Large-scale synthesis of hierarchical MnO_2 for benzene catalytic oxidation显示文摘Hierarchical sea-urchin-shaped manganese oxide microspheres were synthesized via a tacile metnoa based on the reaction between KMnO_4 and MnSO_4 in HNO_3 solution at 50 C.The average diameter of the microspheres is ~850 nm.The microspheres consist of a core of diameter of ~800 nm and nanorods of width ~50 nm.The nanorods exist at the edge of the core.The Brunauer-Emmett-Teller surface area of the sea-urchin-shaped microspheres is 259.4 m^2/g.A possible formation mechanism of the hierarchical sea-urchin-shaped microspheres is proposed.The temperature for 90%conversion of benzene(T_(90)%) on the hierarchical urchin-shaped MnO_2 microspheres is about 218℃. | Dongyan Li Genli Shen Wenxiang Tang Haidi Liu Yunfa Chen | 2014 | Particuology2014，12，3： | 4 |
| 2 | Experimental Study on the Electrical Conductivity of Orthopyroxene at High Temperature and High Pressure under Different Oxygen Fugacities显示文摘At presure 1.0–4.0 GPa and temperature 1073–1423 K and under oxygen partial pressure conditions, a YJ-3000t multi-anvil solid high-pressure apparatus and Sarltron-1260 Impedance/Gain-Phase analyzer were employed toconduct an in-situ measurement of the electrical conductivity of orthopyroxene. The buffering reagents consist of Ni+NiO,Fe+Fe3O4, Fe+FeO and Mo+MoO2 in order to control the environmental oxygen fugacity. Experimental results made clearthat: (1) within the measuring frequency range from 10? to 106 Hz, the complex impedance (R) is of intensive dependence 1on the frequency; (2) The electrical conductivity (σ) tends to increase along to the rise of temperature (T), and Log σ vs. 1/T fit the Arrenhius linear relations; (3) Under the control of oxygen buffer Fe+Fe3O4, with the rise of pressure, theactivation enthalpy tends to increase whereas the electrical conductivity tends to decrease. The activation energy andactivation volume of the main current carriers of orthopyroxene have been obtained, which are (1.715±0.035) eV and (0.03±0.01) cm3/mol, respectively; (4) Under given pressure and temperature, the electrical conductivity tends to increase withincreasing oxygen fugacity, while under given pressure the activation enthalpy tends to decrease with increasing oxygenfugacity; and (5) The sample’s small polarons mechanism has provided a reasonable explanations to the conductionbehavior at high temperature and high pressure. | DAI Lidong LI Heping LIU Congqiang SHAN Shuangming CUI Tongdi SU Genli | 2005 | Acta Geologica Sinica(English Edition)2005，79，6： | 4 |
| 3 | Impedance spectra of hot, dry gabbro at high temperature and pressure显示文摘Impedance spectra of hot, dry gabbro have been studied at 1.0~2.0 Gpa and 593~1173 K.The experimental results indicate that complex impedance depends on frequency of altering current. Impedance arcs representing grain interiors and grain boundaries conduction mechanism are displayed in the complex impedance plane. The impedance arc corresponding to grain interiors occurs over the range of 102~105 Hz, and the impedance arc corresponding to grain boundaries occurs over the range of 12~102 Hz. Each element of equivalent circuit corresponding to grain interiors is fit for complex nonlinear least square program. When garnet occurs in gabbro, the electrical conductivity of gabbro abruptly changes. | WANG Duojun, LIU Congqiang, LI Heping, YI Li, SU Genli and DING Dongye( Laboratory for Study of the Earth’s Interior and Geofluids, Institute of Geochemistry, Chinese Academy of Sciences, Guiyang 550002, China Institute of Geochemistry, Chinese Academy of Sciences, Guiyang 550002, China) | 2002 | Progress in Natural Science:Materials International2002，12，5： | 3 |

| 9 | Formation and evolution of gas flow channels in the abutment pressure area显示文摘The permeability of coal ahead of the working face obviously changes dues to changes in abutment pressure.The formation and evolution of gas flow channels within the abutment pressure area was studied by analyzing the fracture extension mechanism and fracture development in different zones of the abutment pressure area.Fracture and damage mechanics theory is used to understand the observations.The following two techniques were used to understand the evolution of gas flow channels:field observation of the characteristic fractures at different positions relative to the working face and fluorescence micrographs of prepared coal samples.Bending tensile fractures develop along an approximately vertical direction that forms a microscopic network of channels in areas of stress concentration.The abutment pressure affects the local stress and,hence,the local gas conduction.The fractures induced by large deformation and plastic flow form macroscopically networked channels in the reduced stress area.Closer to the working face the gas flow channels evolve from microscopic to macroscopic and from isolated to network.Gas permeability continuously increases during this time.This is corroborated by field observations of the displacement of top coal and the gas flow from gas extraction drillings. | Zhang Yong Zhang Xibin Xu Lifeng Zhang Jiangli Zhou Genli | 2012 | International Journal of Mining Science and Technology2012，22，6： | 1 |

| 11 | SiO_2 glasses synthesized at 355—445℃ and 2.0—5.5 GPa显示文摘A series of SiO2 glasses were synthesized by using spectroscopically pure silica on the YJ-3000 multi-anvil apparatus at 355—445℃ and 2.0—5.5GPa. Their spectroscopic characteristics resemble that of the high-density quartz glass. In the meantime, the IR spectra of SiO2 glasses show that a small amount of water exists in SiO2 glasses in the form of OH-. It may be due simply to the small amount of water that contributes significantly to the amorphism of SiO2.The determination of refraction indices of SiO2 glasses shows that the refraction indices of SiO2 glasses and the high-density quartz glass are in good logarithmic relation with synthetic pressures. | DING Dongye, XIE Hongsen, SU Genli, GUO Jie, JIANG Dayong, XU Zuming and ZHANG YuemingInstitute of Geochemistry , Chinese Academy of Sciences , Guiyang 550002 , China | 1999 | Chinese Science Bulletin1999，44，13： | 0 |
