2Dendrite-free all-solid-state lithium batteries with lithium phosphorous oxynitride-modified lithium metal anode and composite solid electrolytes显示文摘Dendrite formation on lithium (Li) metal anode is a key issue which hinders the development of rechargeable Li battery seriously. A novel method for suppress!ng Li dendrites via using Li phosphorous oxynitride (UPON) modified Li anode and Li1.5Al0.5Ge1.5(PO4)3-poly(ethylene oxide)(Li bistrifluoromethane-sulfonimide)(LAGP-PEO(LiTFSI)) composite solid electrolyte in all-solid-state Li battery is proposed, and the effect of the thickness of UPON on Li anode performarice is also studied. LiPON film with a thickness of 500 nm exhibits satisfactory interface property between Li metal anode and the LAGP-PEO(LiTFSI) solid electrolyte. The LiPON film provides a uniform Li^+ flux across the interface and effectively inhibits the formation of Li dendrites in all-solid-state Li batteries. The assembled all-solid-state Li cell Li(LiPON)/LAGP-PEO(LiTFSI)/LiFePO4 delivers an initial discharge capacity of 152.4 mAh·g^-1 and exhibits good cycling stability and rate performanee at 50 ℃.Chunhua Wang Guoliang Bai Yifu Yang Xingjiang Liu Huixia Shao 2019Nano Research2019,12,1:8
3A novel monoclinic manganite/multi-walled carbon nanotubes composite as a cathode material of lithium-air batteries显示文摘A novel composite of monoclinic manganite/multi-walled carbon nanotubes(c-MnOOH/MWCNTs)composite as a cathode material of lithium-air batteries was successfully synthesized by a simple one-step hydrothermal method.Owing to the unique three-dimensional network of c-MnOOH embedded in the porous structure of MWCNTs,the c-MnOOH/MWCNTs composite could have an advantage of high electrocatalytic activities over those of two other kinds of cathode materials(MWCNTs and c-MnOOH/MWCNTs mixture).The results of chargedischarge tests showed that the c-MnOOH/MWCNTs composite as a cathode material of lithium-air batteries could effectively enhance the catalytic activity for the oxygen evolution reduction(OER)process.The lithium-air battery based on c-MnOOH/MWCNTs composite exhibits low charge potential and high discharge capacity.Ming Zhang Qiang Xu Lin Sang Fei Ding Xingjiang Liu 2014Chinese Science Bulletin2014,59,24:6
4Casting structure of pure aluminum by electric pulse modification at different superheated temperatures显示文摘Electric pulse modification (EPM) is a novel technique that reduces grain size by altering the structure of a melt. It was investigated that the response of the casting structure of high pure aluminum to EPM in different superheated melts. The results indi- cate that the grain refining effect of a given pulse electric field holds an optimal temperature range, moreover, a lower or higher su- perheated temperature will both disadvantage the improvements of casting structure. It essentially lies in the cooperative action be- tween the distorted absorption of clusters and the activated capability of atoms in the aluminum melt.Jingang Qi Jianzhong Wang Xingjiang Liu Bing Wang Daqiang Cang 2005Journal of University of Science and Technology Beijing2005,12,6:6

7Temperature-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 2017Science Bulletin2017,62,13:4

10Electronic structure of exfoliated millimeter-sized monolayer WSe2 on silicon wafer显示文摘The mono layer WSe2 is in teresting and important for future application in nanoelectronics,spintronics and valleytronics devices,because it has the largest spin splitting and Ion gest valley coherence time among all the known monolayer transition-metal dichalcogenides(TMDs).Toobtain the large-area monolayer TMDs'crystal is the first step to manu facture scalable and high-performance electronic devices.In this letter,we have successfully fabricated millimeter-sized mono layer WSe2 single crystals with very high quality,based on our improved mecha nicalexfoliation method.With such superior samples,using standard high resolution angle-resolved photoemission spectroscopy,we didcomprehe nsive electronic band structure measurements on our mono layer WSe2.The overall band features point it to be a 1.2 eV direct bandgap semico nductor.Its spin splitting of the valence band at K point is found as 460 meV,which is 30 meV less than the corresponding band splitting in its bulk counterpart.The effective hole masses of valence bands are determined as 2.344 me atГ,and 0.529 me as well as 0.532 meat K for the upper and lower branch of splitting ban ds,respectively.And screening effect from substrate is shown to substa ntially impact onthe electronic properties.Our results provide importa nt insights into band structure engineering in mono layer TMDs.Our mono layer WSe2 crystals may constitute a valuable device platform.Wenjuan Zhao Yuan Huang Cheng Shen Cong Li Yongqing Cai Yu Xu Hongtao Rong Qiang Gao Yang Wang Lin Zhao Lihong Bao Qingyan Wang Guangyu Zhang Hongjun Gao Zuyan Xu Xingjiang Zhou Guodong Liu 2019Nano Research2019,12,12:2

13Effectiveness and safety of Suxiao Jiuxin pill in treating acute coronary syndrome:a systematic review and Meta-analysis显示文摘OBJECTIVE:To evaluate the effectiveness and safety of Suxiao Jiuxin pill(SX)in acute coronary syndrome(ACS)treatment.METHODS:An extensive search of four English databases(Medline/PubMed,Cochrane Library,Embase,and World Health Organization International Clinical Trials Registration Platform)and four Chinese databases(Chinese National Knowledge Infrastructure,Wanfang,China Science and Technology Journal,and Chinese Biomedical Literature Service System)was performed.Randomized,controlled trials(RCTs)involving SX combined with conventional therapy versus conventional therapy were included.The extracted data included populations,interventions,outcomes,and risk of bias.The cardiovascular events served as the primary outcome.Review Manager 5.3 software was used for data analysis.Relative risks(RRs)with 95%confidence intervals(CIs)were the effect measure.RESULTS:A total of eight RCTs with 979 patients were included.There were 559 patients with unstable angina(UA)in six RCTs and 420 patients with acute myocardial infarction(AMI)in two RCTs.Our review showed that SX plus conventional therapy might reduce the incidence of the total endpoint(RR:0.34,95%CI:0.17,0.68,P=0.002),with no obvious adverse events(RR:1.29,95%CI:0.60,2.77,P=0.52)compared with conventional therapy for patients with UA.Additionally,SX plus conventional therapy also reduced the incidence of the total endpoint(RR:0.35,95%CI:0.18,0.68,P=0.002)compared with conventional therapy in patients with AMI.SX plus conventional therapy also reduced the incidence of ventricular fibrillation(RR:0.23,95%CI:0.10,0.57,P=0.001)compared with conventional therapy in patients with AMI.CONCLUSION:Our results suggest that SX is beneficial for treating patients with UA or AMI.However,our findings should be treated with caution because of the poor methodological quality of the included trials.Therefore,more multicenter,large-sample,high-quality RCTs are required to provide high-quality evidence.Liu Chao Duan Lian Huang Mingyan Li Jun Xiong Xingjiang Chen Guang He Haoqiang Zhang Zhenpeng Wang Jie 2020Journal of Traditional Chinese Medicine2020,40,4:1
14Emergence of superconductivity from fully incoherent normal state in an iron-based superconductor (Ba_(0.6)K_(0.4))Fe_2As_2显示文摘In unconventional superconductors, it is generally believed that understanding the physical properties of the normal state is a pre-requisite for understanding the superconductivity mechanism. In conventional superconductors like niobium or lead, the normal state is a Fermi liquid with a well-defined Fermi surface and well-defined quasipartcles along the Fermi surface. Superconductivity is realized in this case by the Fermi surface instability in the superconducting state and the formation and condensation of the electron pairs(Cooper pairing). The high temperature cuprate superconductors, on the other hand, represent another extreme case that superconductivity can be realized in the underdoped region where there is neither well-defined Fermi surface due to the pseudogap formation nor quasiparticles near the antinodal regions in the normal state. Here we report a novel scenario that superconductivity is realized in a system with well-defined Fermi surface but without quasiparticles along the Fermi surface in the normal state.High resolution laser-based angle-resolved photoemission measurements have been performed on an optimally-doped iron-based superconductor(Ba_(0.6)K_(0.4))Fe_2As_2. We find that, while sharp superconducting coherence peaks emerge in the superconducting state on the hole-like Fermi surface sheets, no quasiparticle peak is present in the normal state. Its electronic behaviours deviate strongly from a Fermi liquid system. The superconducting gap of such a system exhibits an unusual temperature dependence that it is nearly a constant in the superconducting state and abruptly closes at Tc. These observations have provided a new platform to study unconventional superconductivity in a non-Fermi liquid system.Jianwei Huang Lin Zhao Cong Li Qiang Gao Jing Liu Yong Hu Yu Xu Yongqing Cai Dingsong Wu Ying Ding Cheng Hu Huaxue Zhou Xiaoli Dong Guodong Liu Qingyan Wang Shenjin Zhang Zhimin Wang Fengfeng Zhang Feng Yang Qinjun Peng Zuyan Xu Chuangtian Chen Xingjiang Zhou 2019Science Bulletin2019,64,1:1
15Direct bandgap engineering with local biaxial strain in few-layer MoS2 bubbles显示文摘Nano Research volume 13,pages2072–2078(2020)Cite this article 211 Accesses Metrics details Abstract Strain engineering provides an important strategy to modulate the optical and electrical properties of semiconductors for improving devices performance with mechanical force or thermal expansion difference.Here,we present the investigation of the local strain distribution over few-layer MoS2 bubbles,by using scanning photoluminescence and Raman spectroscopies.We observe the obvious direct bandgap emissions with strain in the few-layer MoS2 bubble and the strain-induced continuous energy shifts of both resonant excitons and vibrational modes from the edge of the MoS2 bubble to the center(10μm scale),associated with the oscillations resulted from the optical interference-induced temperature distribution.To understand these results,we perform ab initio simulations to calculate the electronic and vibrational properties of few-layer MoS2 with biaxial tensile strain,based on density functional theory,finding good agreement with the experimental results.Our study suggests that local strain offers a convenient way to continuously tune the physical properties of a few-layer transition metal dichalcogenides(TMDs)semiconductor,and opens up new possibilities for band engineering within the 2D plane.Yang Guo Bin Li Yuan Huang Shuo Du Chi Sun Hailan Luo Baoli Liu Xingjiang Zhou Jinlong Yang Junjie Li Changzhi Gu 2020Nano Research2020,13,8:1

17Electrochemical reversibility of magnesium deposition-dissolution on aluminum substrates in Grignard reagent/THF solutions显示文摘The electrochemical behavior of magnesium deposition-dissolution on scratched aluminum foils in Grignard reagent/tetrahydrofuran (THF) solutions (1 mol L-1 EtMgBr/THF), which is regarded as a potential electrolyte of rechargeable magnesium batteries, was studied by using various methods such as cyclic voltammetry (CV), scanning electron microscopy (SEM), X-ray diffraction (XRD) and charge-discharge (deposition-dissolution) tests. The results present that the obtained magnesium deposits do not exhibit the morphology of dendrite and the Mg-Al alloy is not found on the surface of aluminum foils. The magnesium deposited on the aluminum substrates have excellent electrochemical cyclic performance in 1 mol L-1 EtMgBr/THF solution. The aluminum can be used as a candidate material of the negative current collector for rechargeable magnesium batteries.CHENG Gang XU Qiang ZHANG Ming DING Fei LIU XingJiang JIAO LiFang 2013Chinese Science Bulletin2013,58,27:1

20In situ carrier tuning in high temperature superconductor Bi2Sr2CaCu2O(8+δ)by potassium deposition显示文摘We report a successful tuning of the hole doping level over a wide range in high temperature superconductor Bi_2Sr_2CaCu_2O_(8+δ)(Bi2212) through successive in situ potassium(K) deposition. By taking high resolution angleresolved photoemission measurements on the Fermi surface and band structure of an overdoped Bi2212(T_c= 76 K) at different stages of K deposition, we found that the area of the hole-like Fermi surface around the Brillouin zone corner(p,p) shrinks with increasing K deposition. This indicates a continuous hole concentration change from initial 0.26 to eventual 0.09 after extensive K deposition, a net doping level change of 0.17 that makes it possible to bring Bi2212 from being originally overdoped, to optimally-doped, and eventually becoming heavily underdoped. The electronic behaviors with K deposition are consistent with those of Bi2212 samples with different hole doping levels. These results demonstrate that K deposition is an effective way of in situ controlling the hole concentration in Bi2212. This work opens a good way of studying the doping evolution of electronic structure and establishing the electronic phase diagram in Bi2212 that can be extended to other cuprate superconductors.Yuxiao Zhang Cheng Hu Yong Hu Lin Zhao Ying Ding Xuan Sun Aiji Liang Yan Zhang Shaolong He Defa Liu Li Yu Guodong Liu Xiaoli Dong Genda Gu Chuangtian Chen Zuyan Xu Xingjiang Zhou 2016Science Bulletin2016,61,13:1
