| 1 | The 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 | 1997 | Chinese Science Bulletin1997，42，12： | 5 |
| 2 | The effect of phase transition on the compressional wave velocity for a trachybasalt at high temperature and high pressure显示文摘Compressional wave velocities in a trachybasalt, from Yichuan County, Henan Province, have been measured at 2.0 GPa and up to 1 350℃ in a YJ-3000 t cubic-anvil highpressure apparatus. The run products have been gained at the same pressure but different temperatures. The observation of the thin sections of the run products indicates that, corresponding to the variation of the compressional wave velocity in the trachybasalt, the phase transition has taken place. The relationship between the change of the compressional wave velocity and the hydrous mineral dehydration, solid-solid phase transformation and partial melting has been discussed. The experimental data presented here are of great importance to elucidating the geological process in the earth’s interior. | Wenge Zhou Hongsen Xie Zhidan Zhao Weiguo Zhu Jie Guo Ji’an Xu | 1999 | Chinese Science Bulletin1999，44，15： | 5 |

| 4 | Dendrite-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 | 2021 | Journal of Energy Chemistry2021，30，4： | 3 |

| 7 | P-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) | 1999 | Journal of Earth Science1999，18，4： | 1 |
| 8 | Lysine acetylation regulates the activity of Escherichia coil S-adenosylmethionine synthase显示文摘离氨酸 acetylation 是最丰富的 translational 以后修正之一。然而,在细菌的这修正的生理的角色大部分是未知的。以前的蛋白质 acetylome 分析证明 Escherichia coli adenosylmethionine synthase (地席) 在 vivo,而是这修正的生物功能经历 acetylation 仍然需要被揭开。在这研究, E 的地席。coli 过去表示、净化。随后的集体 spectrometry 分析证明蛋白质的 12 离氨酸残余是 acetylated。指导地点的 mutagenesis 分析被执行,结果证明 acetylated 离氨酸残余在地席的酶的活动起重要作用。下次, deacetylation 试金被把 CobB 用作 deacetylase 执行,并且结果显示出那 CobB 能在 vitro 的 deacetylate 地席。另外, acetylated 的酶的活动和 deacetylated 地席在 vitro 被比较,并且结果证明 acetylation 在它的酶的活动导致了减少,它能被 CobB deacetylation 颠倒。总的来说,我们的数据建议 CobB 调制 E 的酶的活动。在 vitro 的 coli 地席。 | Manluan Sun Hongsen Guo Guoliang Lu Jing Gu Xude Wang Xian-En Zhang Jiaoyu Deng | 2016 | Acta Biochimica et Biophysica Sinica2016，48，8： | 1 |
| 9 | Study 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 | 1997 | Acta Geologica Sinica(English Edition)1997，71，3： | 1 |
| 10 | High-pressure sound velocity of perovskite-enstatite and the possible composition of the Earth's lower mantle显示文摘The compressional sound velocity VP for enstatite of polycrystalline specimens were measured at pressures from 40 to 140 GPa using the optical analytical techniques under shock loading. The dependence of VP (in km/s) on Hugoniot pressure (P, in GPa) can be described by lnVP= 3.079-0.691 ln(P) + 0.094(lnP)2. VP satisfies Birch’s law: VP= 4.068 + 1.677p, where p is corresponding density, which indicated that enstatite is stable throughout the conditions of the lower mantle. The wave velocity P is 0.5% lower and the wave velocity S is 2% higher than that of PREM respectively. We concluded that the lower mantle is mainly composed of perovskite-(Mg1-x, Fex) SiO3 and only a small amount of (Mg1-x, Fex) O is allowed in it. | Zizheng Gong Hongsen Xie Hui Huo Fuqian Jing Jie Guo Ji’an Xu | 2000 | Chinese Science Bulletin2000，45，10： | 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 |

| 13 | New technique to control in situ oxygen fugacity in water-free high-pressure system──Using Cu-O as an example显示文摘Through inserting a solid oxygen-specific electrolyte (YSZ) inside and exerting an electrical power of direct current outside between the sample and oxygen reservoir (an solid oxygen buffer), oxygen was driven by the power from the cathodic electrode area into the positive electrode area at high temperature and high pressure. In this way, the oxygen fugacity in the sample was in situ controlled independently of temperature and pressure. By using Cu-O system as an example, this technique was proved to be successful. | LI Heping 1, XIE Hongsen 1, GUO Jie 1, ZHANG Yueming 1,XU Zuming 1 and XU Ji’an 2 1.
