1The electrical conductivity of H_2O at 0.21-4.18 GPa and 20 -350℃显示文摘The electrical conductivity of H2O in solid and liquid phases has been measured at 0.21-4.18 GPa and 20-350℃. The results indicate: ( i ) different phases of H2O in solid have different relations between electrical conductivity and temperature and pressure. The conductivity changes continuously with temperature, but discontinuously with the pressure between 2.11 and 2.58 GPa, which corresponds to the transforming pressure between ice (Ⅵ) and ice ( Ⅶ ) ; ( ii ) the con-ductivity of H2O in liquid all increases with temperature and pressure, but there are discontinuities at pressures between 0.57 and 0.9 GPa, and between 2.11 and 2.58 GPa, which are also consistent with the polymorph of ice (ice ( Ⅴ), ice (Ⅵ) and ice ( Ⅶ ) ) . This reflects that H2O in liquid at different pressures has quite different properties of electron chemistry. It is prob-ably the important reason that causes the layers with high electrical conductivity and low velocity in the earth’s crust and upper mantle.ZHENG Haifei, XIE Hongsen, XU Yousheng, SONG Maoshuang, GUO Jie and ZHANG YuemingInstitute of Geochemistry, Chinese Academy of Sciences, Guiyang 550002, China Department of Geology, Peking University, Beijing 100871, China 1997Chinese Science Bulletin1997,42,12:5
2Experimental study on the P wave velocity in rocks from lower crust and crust-mantle transitional zone beneath the Hannuoha显示文摘Cenozoic basalt-borne mafic granulite-facies plagioclase pyroxenite and eclogite-facies garnet pyroxenite xenoliths from the Hannuoba, as well as nearby Archean terrain granulites, are selected for the experimental study on the P wave velocity at high temperature and high pressure in order to reveal the present-day compositional features for the lower crust and crust-mantle transitional zone. Results show that mafic xenoliths have high Vp (7.0~8.0 km/s), in contrast, the Archean terrain granulites have low Vp (<7.0 km/s). High Vp mafic xenoliths can represent the present-day compositional features for the lower crust and crust-mantle transitional zone beneath the Hannuoba. This provides new evidence for the crust vertical growth and the formation of the crust-mantle transitional zone resulting from the magma underplating. Low Vp Archean granulite still remains the characteristics of the early lower crust.FAN Qicheng SUI Jianli ZHANG Hongfu ZHAI Mingguo and XIE Hongsen(1.

5Dendrite-structured FeF_(2) consisting of closely linked nanoparticles as cathode for high-performance lithium-ion capacitors显示文摘Lithium-ion capacitors(LICs)are regarded as a good choice for next-generation energy storage devices,which are expected to exhibit high energy densities,high power densities,and ultra-long cycling stability.Nevertheless,only a few battery-type cathode materials with limited kinetic properties can be employed in LICs,and their electrochemical properties need to be optimized urgently.Here,we exploit a new dendrite-structured FeF_(2) consisting of closely linked primary nanoparticles using a facile solvothermal method combined with the subsequent annealing treatment.This particular architecture has favorable transport pathways for both lithium ions and electrons and exhibits an ultrafast chargedischarge capability with high reversible capacities.Furthermore,a well-designed LIC employing the prepared dendrite-structured FeF_(2) as the battery-type cathode and commercialized activated carbon(AC)as supercapacitor-type anode was constructed in an organic electrolyte containing Li ions.The LIC operates at an optimal voltage range of 1.1-3.8 V and shows a maximum high energy density of 152 W h kg^(-1) and a high power density of 4900 W kg^(-1) based on the total mass of cathode and anode.Long-term cycling stability(85%capacity retention after 2000 cycles)was achieved at 1 A g^(-1).This work suggests that the dendrite-structured FeF_(2) is a prime candidate for high-performance LICs and accelerates the development of hybrid ion capacitor devices.Huanyu Liang Zhengqiang Hu Zhongchen Zhao Dong Chen Hao Zhang Huaizhi Wang Xia Wang Qiang Li Xiangxin Guo Hongsen Li 2021Journal of Energy Chemistry2021,30,4:3

10P-Wave Velocity in Rocks of Dabieshan, China at High Pressure and High Temperature: Constraints for Composition of Lower Crust and Crust-Mantle Recycling显示文摘P-wave velocities in the rocks of Dabieshan, central China were measured at pressures up to 5.0 GPa and temperatures up to 1 300℃. The ultrahigh pressure eclogites have the highest density and P-wave velocity (Vp) and lower anisotropy. Pressure derivatives of the eclogites range from 0. 22 to 0. 33 km. s-1 GPa-1. Average temperature derivative of the eclogites is - 3. 41×10-4 km. s-1. °C -1. The density and VP of the eclogites imply that there will be two united possibilities related to crust-mantle recycling after the eclogite formed in the deep lithosphere. One is that some eclogites in the deep lithosphere were detached and sunk into deeper mantle due to their denser density. Another is that some eclogites returned to the crust and exposed to the surface.Small amounts (<12%) of eclogites may be still exist in the deep crust beneath Dabieshan based on our calculation.Zhao Zhidan Zhou Wenge Xie Hongsen Guo Jie Xu Zuming(Institute of Geochemistry, Chinese Academy of Sciences, Guiyang 550002)Zhang Zeming(Institute of Geology, Chinese Academy of Geological Sciences, Beijing 100037) 1999Journal of Earth Science1999,18,4:1

13In-situ growth of CNTs encapsulating P-doped NiSe_(2) nanoparticles on carbon framework as efficient bifunctional electrocatalyst for overall water splitting显示文摘Nickel diselenide(NiSe_(2)) is a promising low-cost catalyst for both hydrogen evolution reaction(HER) and oxygen evolution reaction(OER),due to its suitable d-electron configuration and high electrical conductivity.Several representative elements,e.g.,Co,Fe and P,have been utilized as cation or anion to promote the electrocatalytic activity of NiSe_(2) by modulating the interaction with Se element,whilst the catalyst stability is less concerned.In this work,the catalytic Ni nanoparticles were in-situ encapsulated in carbon nanotubes grown on three-dimensional conducting carbon framework.Subsequent phosphorization and selenization yield dispersed P-doped NiSe_(2) nanoparticles protected by carbon shell with highly exposed yet stable active sides,resulting in significantly promoted HER and OER activities as well as accelerated kinetics.In detail,the P-NiSe_(2)@N-CNTs/NC hybrid catalyst deliver low overpotentials of 95 and 306 mV at10 mA cm^(-2) for HER and OER in alkaline media,respectively.DFT calculations reveal that P doping reduces the electron density surrounding Ni atoms while accumulates the charges to Se, respectively,which in turn reduces the energy barriers for both water dissociation and intermediates adsorption for both HER and OER.As a concept of proof,a cell assembled by P-NiSe_(2)@N-CNTs/NC hybrid catalystbased anode and cathode performs a low applied voltage of 1.609 V to reach 10 mA cm^(-2),and outstanding long-term stability.Jing Yu Wei-Jian Li Guibo Kao Cheng-Yan Xu Rongrong Chen Qi Liu Jingyuan Liu Hongsen Zhang Jun Wang 2021Journal of Energy Chemistry2021,30,9:1

19Experimental Study of the Influence of Hydrous Minerals on the Melting Behaviour of Rocks at High Temperatures and Pressures显示文摘The experimental study on the melting of potassic basalt and eclogite with about 2% waterat 800-1300℃ and 1.0-3.5 GPa shows that the solidi of both rocks are significantly lower thanthose obtained from the previous experiments of the same type of rocks under dry conditions,and the former which is enriched in potassium has a lower melting point than the latter. It is con-sistent with the previous study. The melting temperature of eclogite increases with pressure,whereas potassic basalt has similar properties only at 1.5—2.5 GPa and>3.0 GPa, and at 2.5—3.0 GPa the melting temperature decreases with pressure. This can be explained as follows: (1)eclogite only has one hydrous mineral amphibole and the dehydous temperature is lower than thewet solidus of the rock. (2) Amphibole exists in potassic basalt at the pressures lower than 2.5GPa and phlogopite exists at pressures higher than 2.5 GPa, and the special compositions of bothminerals determine that amphibole has a dehydration temperature higher than or close to that ofthe wet solidus of the rocks, while phlogopite has a dehydration temperature lower than that ofthe wet solidus. On the other hand the features of the continuous solidus in the experiment ofhydrous eclogite were produced by the fact that the dehydration temperature of its amphibolelower than or close to the melting temperature of the hydrous conditions. So the melting tempera-ture lowers at higher pressures. Therefore, the composition of the rocks in the lithosphere and thetypes of hydrous minerals and their stable P-T conditions are the important factors controllingthe solidi of rocks. It can quite well explain the partial melting of rocks and the origin of the lowvelocity zone in the deep lithosphere.Zheng Haifei Xie Hongsen Xu Yousheng Song Maoshuang Zhang Yueming Wang Mingzai and Xu Huigang Department of Geology, Peking University, Beijing Institute of Geochemistry, Chinese Academy of Sciences, Guiyang,Guizhou 1996Acta Geologica Sinica(English Edition)1996,70,2:1
20Study on the Electrical Conductivity of 0.025 mol NaCl Solution at 0.25-3.75 GPa and 20-370℃显示文摘The electrical conductance of 0.025 mol NaCl solution was measured at0.25-3.75 GPa and 20-370℃. As shown by the results, the conductance increases with temper-ature, and there is a liner relation between the reciprocal of temperature and the logarithm ofthe conductance but their slopes are different at different pressures. The relations between theconductance and pressure is rather complex and there are some discontinuities: in the range of2.25-3.75 GPa, the conductance increases with the pressure; in the range of 1.25-2.0 GPa, theconductance is not related to the pressure; and at a pressure of 0.75 GPa, the conductance ishigher than that at the pressures nearby. This reflects that the NaCl solution has rather differentproperties of electronic chemistry at various pressures, and probably is an important cause forthe existence of the layers with high electrical conductance and low velocity in the Earth’s crustand mantle.Zheng Haifei Xie Hongsen Xu Yousheng Song Maoshuang Guo Jie and Zhang Yueming Earth’s Interior Material Laboratory,Institute of Geochemistry,Chinese Academy of Sciences,Guiyang,Guizhou 1997Acta Geologica Sinica(English Edition)1997,71,3:1
