| 1 | Palaeodietary study of Sanxingcun Site,Jintan,Jiangsu显示文摘C and N stable isotope ratios of 19 human bones in Sanxingcun Site, Jintan, Jiangsu Province, were measured to explore the lifestyle and social economic structure. Although the bone collagen degraded to different extents, the atomic ratio of C/N was located in the range of 2.9-3.6, indicating that they were preserved very well. Average δ13C value (20.05±0.21‰), average δ 15N value (9.69 ±0.33‰) and poor positive correlation between each other suggested that rice agriculture was dominant with hunt-ing-fishing supplemented in human lifestyle. Poor negative correlation between δ 15N values and C3 percentages of foods implied relative independence of rice agriculture and hunting-fishing. Compared to Hemudu Site and Qingpu Site, rice agriculture was developed further, but hunting-fishing decreased. The mode for people in Sanxingcun Site to get the meat was still in the initial exploitation. | HU YaoWu WANG GenFu CUI YaPing DONG Yu GUAN Li WANG ChangSui | 2007 | Chinese Science Bulletin2007，52，5： | 4 |
| 2 | Temperature-induced Lifshitz transition in topological insulator candidate HfTe_5显示文摘The ongoing discoveries and studies of novel topological quantum materials have become an emergent and important field of condensed matter physics.Recently,HfTe_5 ignited renewed interest as a candidate of a novel topological material.The single-layer HfTe_5 is predicted to be a two-dimensional large band gap topological insulator and can be stacked into a bulk that may host a temperature-driven topological phase transition.Historically,HfTe_5 attracted considerable interest for its anomalous transport properties characterized by a peculiar resistivity peak accompanied by a sign reversal carrier type.The origin of the transport anomaly remains under a hot debate.Here we report the first high-resolution laser-based angle-resolved photoemission measurements on the temperature-dependent electronic structure in HfTe_5.Our results indicated that a temperature-induced Lifshitz transition occurs in HfTe_5,which provides a natural understanding on the origin of the transport anomaly in HfTe_5.In addition,our observations suggest that HfTe_5 is a weak topological insulator that is located at the phase boundary between weak and strong topological insulators at very low temperature. | Yan Zhang Chenlu Wang Guodong Liu Aiji Liang Lingxiao Zhao Jianwei Huang Qiang Gao Bing Shen Jing Liu Cheng Hu Wenjuan Zhao Genfu Chen Xiaowen Jia Li Yu Lin Zhao Shaolong He Fengfeng Zhang Shenjin Zhang Feng Yang Zhimin Wang Qinjun Peng Zuyan Xu Chuangtian Chen Xingjiang Zhou | 2017 | Science Bulletin2017，62，13： | 4 |
| 3 | Very high upper critical fields of F-doped Fe-based layered superconductors NdO_(0.88)F_(0.12)FeAs and CeO_(0.88)F_(0.12)FeAs显示文摘Using the solid state reaction method, we have synthesized the polycrystalline F-doped NdO0.88F0.12FeAs and CeO0.88F0.12FeAs with the superconducting transition temperatures at about 48 and 40 K, respectively. To obtain the upper critical field Hc2 of Nd(Ce)O0.88F0.12FeAs samples, we measured the electrical resistivity under magnetic field up to 14 T. Based on the Werthamer-Helfand-Hohenberg (WHH) rela-tion together with the Hc2(T) curves in a relatively high field, we estimated that these superconductors have a rather high upper critical field of about 115 T for Nd-based and 107 T for Ce-based samples, indicating the similarities between these ReO1-xFxFeAs (Re = rare earth element) superconductors and high Tc cuprate su-perconductors. | WU Dan, LI Zheng, SU ShaoKui, DONG Jing, LI Gang, HU WanZheng, ZHENG Ping, CHEN GenFu, LUO JianLin & WANG NanLin Institute of Physics, Chinese Academy of Sciences, Beijing 100190, China | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，6： | 2 |
| 4 | Understanding Dual-Polar Group Functionalized COFs for Accelerating Li-Ion Transport and Dendrite-Free Deposition in Lithium Metal Anodes显示文摘Lithium metal batteries(LMBs)have attracted wide attentions because of their high theoretical specific capacity and low electrochemical potential.However,the growth of lithium dendrites seriously affects the practical application of LMBs.Thus,the lithium-philic carbonyl and carboxy dualgroup-modified covalent organic framework(COF-COOH)is designed to coat the polypropylene(PP)separator(COF-COOH@PP separator),realizing the regulation of ion transport and uniform lithium deposition.The plentiful and negative charge sites in the COF-COOH can suppress the diffusion of the freely movable lithium salt anion by the electrostatic interaction.Density functional theory(DFT)calculations demonstrate that the COF-COOH possesses the function of anchoring anion and desolvation.Consequently,the Li^(+)transference number(0.7),ion conductivity(0.64 mS cm^(-1)),and desolvating of Li^(+)are obviously improved by using the COF-COOH@PP separator.The modified Li-Li symmetric battery delivers stable cycle for more than 1000 h and lower voltage hysteresis(0.02 V).This dendrite-free deposition strategy holds great promise for practical application of Li metal anodes. | Qi An Hong-en Wang Genfu Zhao Shimin Wang Lufu Xu Han Wang Yao Fu Hong Guo | 2023 | Energy & Environmental Materials2023，6，2： | 1 |

| 8 | Oxygen vacancies with localized electrons direct a functionalized separator toward dendrite-free and high loading LiFePO_(4)for lithium metal batteries显示文摘The pursuit of high energy density has promoted the development of high-performance lithium metal batteries(LMBs).However,the underestimated but non-negligible dendrites of Li anode have been observed to shorten battery lifespan.Herein,a composite separator(TiO_(2-x)@PP),in which TiO_(2)with electron-localized oxygen vacancies(TiO_(2-x))is coated on a commercial PP separator,is fabricated to homogenize lithium ion transport and stabilize the lithium anode interface.With the utilization of TiO_(2-x)@PP separators,the symmetric lithium metal battery displays enhanced cycle stability over 800 h under a high current density of 8 m A cm^(-2).Moreover,the LMBs assembled with high-loading LiFePO_(4)(9.24 mg cm^(-2))deliver a stable cycling performance over 900 cycles at a rate of 0.5 C.Comprehensive theoretical studies based on density functional theory(DFT)further unveil the mechanism.The favorable TiO_(2-x)is beneficial for facilitating fast Li+migration and impeding anions transfer.In addressing the Li dendrite issues,the use of TiO_(2-x)@PP separator potentially provides a facile and attractive strategy for designing well-performing LMBs,which are expected to meet the application requirements of rechargeable batteries. | Qi An Qing Liu Shimin Wang Lixiang Liu Han Wang Yongjiang Sun Lingyan Duan Genfu Zhao Hong Guo | 2022 | Journal of Energy Chemistry2022，，12： | 0 |
