| 1 | When water meets iron at Earth's core-mantle boundary显示文摘Hydrous minerals in subducted crust can transport large amounts of water into Earth's deep mantle. Our laboratory experiments revealed the surprising pressure-induced chemistry that, when water meets iron at the core-mantle boundary, they react to form an interlayer with an extremely oxygen-rich form of iron, iron dioxide, together with iron hydride. Hydrogen in the layer will escape upon further heating and rise to the crust, sustaining the water cycle. With water supplied by the subducting slabs meeting the nearly inexhaustible iron source in the core, an oxygen-rich layer would cumulate and thicken, leading to major global consequences in our planet. The seismic signature of the D″ layer may echo the chemical complexity of this layer. Over the course of geological time, the enormous oxygen reservoir accumulating between the mantle and core may have eventually reached a critical eruption point. Very large-scale oxygen eruptions could possibly cause major activities in the mantle convection and leave evidence such as the rifting of supercontinents and the Great Oxidation Event. | Ho-Kwang Mao Qingyang Hu Liuxiang Yang Jin Liu Duck Young Kim Yue Meng Li Zhang Vitali B.Prakapenka Wenge Yang Wendy L.Mao | 2017 | National Science Review2017，4，6： | 14 |
| 2 | Influence of nonionic surfactant on the solubilization and biodegradation of phenanthrene显示文摘Phenanthrene was solubilized in two different nonionic surfactants, Tween80 and Triton X-100. The bioavailability of phenanthrene to the bacteria isolated from the petroleum contaminated soils was studied based on the rotary flasks experiments. The results showed that the concentration of nonionic surfactants above the critical micelle concentration(CMC) can increase the solubility of phenanthrene in water and were innoxious to the phenanthrene-degrading bacteria; phenanthrene solubilized in the micelles of Tween80 was bioavailable and biodegradable. The research demonstrated the potential of surfactant-enhanced bioremediation of soils contaminated by hydrophobic organic compounds(HOCs). | YANGJian-gang LIUXiang LONGTao YUGang PENGShe ZHENGLiu | 2003 | Journal of Environmental Sciences2003，15，6： | 8 |
| 3 | ANALYTICAL SOLUTION FOR THE VELOCITY FIELD INDUCED BY A UNIFORMLY MOVING HELICAL VORTEX FILAMENT IN CYLINDRICAL TUBE显示文摘A derivation of an analytical expression for the inviscid velocity field induced by a single right handed helical vortex filament is presented. The vortex filament moves uniformly and rigidly without change of form in a cylindrical tube, where the vortex filament rotates around its axis with a constant angular velocity and translates along its axis with a constant translational velocity. The key to solve the problem is to set up a moving cylindrical coordinate system fixed on the vortex filament. The result shows that the velocity field is a time periodic function, and may degenerate into Okulovs’s formula when the helical vortex filament slips along the filament itself or stays immobile. | LiuXiang HuangQi-bai LiaoDao-xun WenGuo-zhen | 2003 | Journal of Hydrodynamics2003，15，1： | 5 |

| 13 | Hydrogen-bonded 1D and 2D Assemblies of Tetraiso-butyl-resorcin[4]arene in the Crystalline State显示文摘X-ray crystal structures of co-crystals involving tetra-iso-butyl-resorcin[4]arene 1 with both acetone and acetonitrile solvents were reported. The component 1?2(CH3)2CO 2 assembles such that the resorcin[4]arene adopts a C2v conformation and the acetone serves as hydrogen bond acceptors, forming a 1D hydrogen-bonded polymer. 2 (C50H68O10) crystallizes in the triclinic, space group P1 with a = 10.0440(7), b = 13.7498(9), c = 17.6374(12) ?, α = 77.726(2), β = 86.733(2), γ = 88.634(2)o, V = 2376.1(3) ?3, Dc = 1.159 g/cm3, and Z = 2. The assembly process of component 1?2CH3CN?H2O 3 yields a 2D hydrogen-bonded polymer formed by intermolecular hydrogen bonds between resorcin[4]arene and water molecules. In the case of component 3, the acetonitrile molecule serves as guest inside the bowl of resorcin[4]arene host. 3 (C48H64N2O9) crystallizes in the monoclinic, space group P2/n with a = 13.7570(18), b = 9.0961(12), c = 19.453(3) ?, β = 103.017(3)o, V = 2371.7(5) ?3, Dc = 1.138 g/cm3, and Z = 2. | LIUXiang LIUYu-Jie ZHANGQian-Feng | 2005 | Chinese Journal of Structural Chemistry2005，24，7： | 0 |
| 14 | Cellular proteomic profiling of esophageal epithelial cells cultured under physioxia or normoxia reveals high correlation of radiation response显示文摘Objective To investigate the radiation response and proteomic profiling of esophageal epithelial cells cultured under physioxia and normoxia.Methods The human immortalized normal esophageal epithelial cell line SHEE cells were cultured under normoxia(21%)and physioxia(4%),respectively.A clonogenic assay was performed to evaluate the radiation response of SHEE cells.Cellular proteomic profiling of SHEE cells maintained under physioxia and normoxia was conducted to determine the differentially expressed proteins.Then,the identified differentially expressed proteins were validated by Western blot.Results SHEE cells exposed to normoxia showed an increased radiation response compared to physioxia(irradiation dose≥10Gy,P<0.05).Over 1200 non-redundant proteins were identified in the collected samples.Protein expression was compared between physioxia and normoxia,42 proteins were downregulated and 45 proteins upregulated,in which oxidative phosphorylation was the most significantly enriched pathway.When cells were cultured under normoxia conditions,the induction of antioxidant genes appeared to contribute to form a phenotype adapted to the environment with high oxygen-content.Further analysis validated NRF2,BIP,VCP,SOD1,and YAP1 were the key regulators of this phenotype.Conclusions Compared with physioxia,normoxic cell culture condition can enhance the radiation response.This study could stimulate in vivo microenvironment,and provide a basis for radiation-induced normal tissue damage. | Hui Luo Yanan Sun Liuxiang Wang Ran Zhao Beggs James | 2023 | Radiation Medicine and Protection2023，4，2： | 0 |
| 15 | No evidence of superconductivity in a compressed sample prepared from lutetium foil and H_(2)/N_(2) gas mixture显示文摘A material described as lutetium–hydrogen–nitrogen(Lu-H-N in short)was recently claimed to have“near-ambient superconductivity”[Dasenbrock-Gammon et al.,Nature 615,244–250(2023)].If this result could be reproduced by other teams,it would be a major scientific breakthrough.Here,we report our results of transport and structure measurements on a material prepared using the same method as reported by Dasenbrock-Gammon et al.Our x-ray diffraction measurements indicate that the obtained sample contains three substances:the facecentered-cubic(FCC)-1 phase(Fm-3m)with lattice parameter a=5.03Å,the FCC-2 phase(Fm-3m)with a lattice parameter a=4.755Å,and Lu metal.The two FCC phases are identical to the those reported in the so-called near-ambient superconductor.However,we find from our resistance measurements in the temperature range from 300 K down to 4 K and the pressure range 0.9–3.4 GPa and our magnetic susceptibility measurements in the pressure range 0.8–3.3 GPa and the temperature range down to 100 K that the samples show no evidence of superconductivity.We also use a laser heating technique to heat a sample to 1800 XC and find no superconductivity in the produced dark blue material below 6.5 GPa.In addition,both samples remain dark blue in color in the pressure range investigated. | Shu Cai Jing Guo Haiyun Shu Liuxiang Yang Pengyu Wang Yazhou Zhou Jinyu Zhao Jinyu Han Qi Wu Wenge Yang Tao Xiang Ho-kwang Mao Liling Sun | 2023 | Matter and Radiation at Extremes2023，8，4： | 0 |

| 17 | The Brittle Fracture Mechanism of Vanadium Alloy with High Level of Oxygen and Hydrogen显示文摘Hydrogen embrittlement is one of the key issues for the vanadium alloys for fusion application. Previous study has shown that V4Ti alloy had better properties against the embrittlement than V4Cr4Ti and V4Ti3A1 alloys. It was thought that the better property was benefited from the small ratio of itsyield strength over its ultimate tensilestrength. | CHENJiming XUZengyu YANGLin LIUXiang | 2001 | Southwestern Institute of Physics Annual Report2001，，1： | 0 |
