| 1 | Mechanism of Functional Responses to Loading of Carbon Fiber Reinforced Cement-based Composites显示文摘Single fiber pull-out testing was conducted to study the origin of the functional responses to loading of carbon fiber reinforced cement-based composites.The variation of electrical resistance with the bonding force on the fiber-matrix interface was measured.Single fiber electromechanical testing was also conducted by measuring the electrical resistance under static tension.Comparison of the results shows that the resistance increasing during single fiber pull-out is mainly due to the changes at the interface.The conduction mechanism of the composite can be explained by the tunneling model.The interfacial stress causes the deformation of interfacial structure and the interfacial debonding,which have influences on the tunneling effect and result in the change of resistance. | JIANG Cuixiang LI Zhuoqiu SONG Xianhui LU Yong | 2008 | Journal of Wuhan University of Technology(Materials Science)2008，23，4： | 6 |
| 2 | Nodeless superconductivity in the kagome metal CsV_(3)Sb_(5)显示文摘The recently discovered kagome metal series AV3Sb5(A=K, Rb, Cs) exhibits topologically nontrivial band structures, chiral charge order and superconductivity, presenting a unique platform for realizing exotic electronic states. The nature of the superconducting state and the corresponding pairing symmetry are key questions that demand experimental clarification. Here, using a technique based on the tunneling diode oscillator, the magnetic penetration depth ?λ(T) of CsV3Sb5 was measured down to 0.07 K. A clear exponential behavior in ?λ(T) with marked deviations from a T or T2 temperature dependence was observed at low temperatures, indicating an absence of nodal quasiparticles. Temperature dependence of the superfiuid density and electronic specific heat can be described by two-gap s-wave superconductivity, consistent with the presence of multiple Fermi surfaces in CsV3Sb5. These results evidence nodeless superconductivity in CsV3Sb5 under ambient pressure, and constrain the allowed pairing symmetry. | Weiyin Duan Zhiyong Nie Shuaishuai Luo Fanghang Yu Brenden R.Ortiz Lichang Yin Hang Su Feng Du An Wang Ye Chen Xin Lu Jianjun Ying Stephen DWilson Xianhui Chen Yu Song Huiqiu Yuan | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，10： | 3 |
| 3 | Orbital ordering and fluctuations in a kagome superconductor CsV_(3)Sb_(5)显示文摘Recently,competing electronic instabilities,including superconductivity and density-wave-like order,have been discovered in vanadium-based kagome metals AV_(3)Sb_(5)(A=K,Rb,Cs)with a nontrivial band topology.This finding stimulates considerable interest to study the interplay of these competing electronic orders and possible exotic excitations in the superconducting state.Here,we performed51V and133Cs nuclear magnetic resonance(NMR)measurements on a CsV_(3)Sb_(5)single crystal to clarify the nature of density-wave-like transition in these kagome superconductors.A first-order structural transition is unambiguously revealed below T_(s)~94 K by observing the sudden splitting of Knight shift in^(51)V NMR spectrum.Moreover,combined with^(133)Cs NMR spectrum,the present result confirms a three-dimensional structural modulation.By further analyzing the anisotropy of Knight shift and 1/T_(1)T at^(51)V nuclei,we proposed that the orbital order is the primary electronic order induced by the firstorder structural transition,which is supported by further analysis on electric field gradient at^(51)V nuclei.In addition,the evidence for possible orbital fluctuations is also revealed above T_(s).The present work sheds light on a rich orbital physics in kagome superconductors AV_(3)Sb_(5). | DianWu Song LiXuan Zheng FangHang Yu Jian Li LinPeng Nie Min Shan Dan Zhao ShunJiao Li BaoLei Kang ZhiMian Wu YanBing Zhou KuangLv Sun Kai Liu XiGang Luo ZhenYu Wang JianJun Ying XianGang Wan Tao Wu XianHui Chen | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，4： | 2 |
| 4 | ELECTRO-THERMAL EFFECTS AND DEFORMATION RESPONSE OF CARBON FIBER MAT CEMENT BEAMS显示文摘A carbon fiber mat is a sheet composed of intercrossing short carbon fibers, which has more stable and lower electrical resistivity compared with dispersed short carbon fiber mixed in cement. Thereby carbon fiber mat cement could exhibit obvious electro-thermal effect. When electrified, the temperature of composite structures made up of cement mortar and carbon fiber mat will rise rapidly. If the temperature field is not uniform, temperature difference will cause structures to deform, which can be used to adjust the deformation of structures. The temperature field and deformation response driven by the electro-thermal effects of a type of carbon fiber mat cement beams are studied. Firstly, the temperature and deformation responses are studied using theories of thermal conduction and elasticity. Secondly, experimental results are given to verify the theoretical solution. These two parts lay the foundation for temperature and deformation adjustment. | Zhu Sirong Li Zhuoqiu Song Xianhui (Department of Engineering Structures and Mechanics,Wuhan University of Technology,Wuhan 430070,China) | 2003 | Acta Mechanica Solida Sinica2003，16，4： | 2 |

| 6 | Coaxing Polysaccharide Granules into Supramolecular Biocolloidal Additives for Papermaking显示文摘In light of developments in polysaccharide-based sustainable processes involving supramolecular interactions,we herein present our findings pertaining to coaxing polysaccharide granules into functional supramolecular biocolloids.Translucent biocolloidal dispersions containing various forms of starch are facilely designable,essentially built upon complexation between disassembled native cornstarch granules and amphiphilic ligands.Oily moieties of guest molecules are dynamically attractable into cavities of helical structures,with cationic groups pointing toward the bulk phase.This noncovalent attraction can generate core-shell biocolloidal particles.The significantly higher gelatinizability of freeze-dried biocolloids in contrast to native cornstarch granules is attributable to complex formation,and a homogenous dispersion is readily formable at room temperature.Our results also show biocolloids'ligand-related antibacterial activity.The use of biocolloids as wet-end additives for biofiber assemblies(cellulosic paper)can enhance mechanical strength,fines retention,and filler bondability.Supramolecular biocolloids with positively charged,translucent,easily gelatinizable,antibacterial,and polysaccharide-bondable functionalities would find tailorable use in the paper industry. | Yongsheng Wang Wenyuan Zhu Xueren Qian Meiyun Zhang Shunxi Song Chuyan Jing Zhengren Meng Shiyu Xu Xianhui An Xiujie Huang Jing Shen | 2020 | Paper And Biomaterials2020，5，2： | 1 |
| 7 | Chemical looping oxidative propane dehydrogenation controlled by oxygen bulk diffusion over FeVO_(4)oxygen carrier pellets显示文摘The oxygen distribution and evolution within the oxygen carrier exert significant influence on chemical looping processes.This paper describes the influence of oxygen bulk diffusion within FeVO4 oxygen carrier pellets on the chemical looping oxidative propane dehydrogenation(CL-ODH).During CL-ODH,the oxygen concentration at the pellet surface initially decreased and then maintained stable before the final decrease.At the stage with the stable surface oxygen concentration,the reaction showed a stable C3H6 formation rate and high C3H6 selectivity.Therefore,based on Fick’s second law,the oxygen distribution and evolution in the oxygen carrier at this stage were further analyzed.It was found that main reactions of selective oxidation and over-oxidation were controlled by the oxygen bulk diffusion.C3H8 conversion rate kept decreasing during this stage due to the decrease of the oxygen flux caused by the decline of oxygen gradient within the oxygen carrier,while C3H6 selectivity increased due to the decrease of overoxidation.In addition,reaction rates could increase with the propane partial pressure due to the increase of the oxygen gradient within the oxygen carrier until the bulk transfer reached its limit at higher propane partial pressure.This study provides fundamental insights for the diffusion-controlled chemical looping reactions. | Hongbo Song Wei Wang Jiachen Sun Xianhui Wang Xianhua Zhang Sai Chen Chunlei Pei Zhi-Jian Zhao | 2023 | Chinese Journal of Chemical Engineering2023，53，1： | 1 |

| 11 | Magnetic-field-induced electronic instability of Weyl-like fermions in compressed black phosphorus显示文摘Revealing the role of Coulomb interaction in topological semimetals with Dirac/Weyl-like band dispersion shapes a new frontier in condensed matter physics.Topological node-line semimetals(TNLSMs),anticipated as a fertile ground for exploring electronic correlation effects due to the anisotropy associated with their node-line structure,have recently attracted considerable attention.In this study,we report an experimental observation for correlation effects in TNLSMs realized by black phosphorus(BP)under hydrostatic pressure.By performing a combination of nuclear magnetic resonance measurements and band calculations on compressed BP,a magnetic-field-induced electronic instability of Weyl-like fermions is identified under an external magnetic field parallel to the so-called nodal ring in the reciprocal space.Anomalous spin fluctuations serving as the fingerprint of electronic instability are observed at low temperatures,and they are observed to maximize at approximately 1.0 GPa.This study presents compressed BP as a realistic material platform for exploring the rich physics in strongly coupled Weyl-like fermions. | Lixuan Zheng Kaifa Luo Zeliang Sun Dan Zhao Jian Li Dianwu Song Shunjiao Li Baolei Kang Linpeng Nie Min Shan Zhimian Wu Yanbing Zhou Xi Dai Hongming Weng Rui Yu Tao Wu Xianhui Chen | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，11： | 0 |
| 12 | Unveiling the charge density wave inhomogeneity and pseudogap state in 1T-TiSe_2显示文摘By using scanning tunneling microscopy(STM)/spectroscopy(STS), we systematically characterize the electronic structure of lightly doped 1 T-TiSe_2, and demonstrate the existence of the electronic inhomogeneity and the pseudogap state. It is found that the intercalation induced lattice distortion impacts the local band structure and reduce the size of the charge density wave(CDW) gap with the persisted 2 × 2 spatial modulation. On the other hand, the delocalized doping electrons promote the formation of pseudogap. Domination by either of the two effects results in the separation of two characteristic regions in real space, exhibiting rather different electronic structures. Further doping electrons to the surface confirms that the pseudogap may be the precursor for the superconducting gap. This study suggests that the competition of local lattice distortion and the delocalized doping effect contribute to the complicated relationship between charge density wave and superconductivity for intercalated 1 T-TiSe_2. | Kai-Wen Zhang Chao-Long Yang Bin Lei Pengchao Lu Xiang-Bing Li Zhen-Yu Jia Ye-Heng Song Jian Sun Xianhui Chen Jian-Xin Li Shao-Chun Li | 2018 | Science Bulletin2018，63，7： | 0 |
| 13 | Multivalent Display of Lipophilic DNA Binders for Dual-Selective Anti-Mycobacterium Peptidomimetics with Binary Mechanism of Action显示文摘We made oligoamidine-based peptidomimetics highly specific for mycobacteria eradication by introducing and arraying lipophilic DNA binding motifs on macromolecular backbones.The short poly(amidino-phenylindole)(PAPI)structures feature an alternating amphiphilic structure with cationic,lipophilic DNA-binding moieties,enabling fast and selective eradication of mycobacteria through binary,membrane-and DNA-selective mechanisms of action.More importantly,PAPIs address the primary treatment challenge by combating mycobacteria in eukaryotic cells and working as a sensitizer for conventional antibiotics,in bothways promoting more thorough removal of pathogens and reducing the mycobacteria’s resistance generation rate during treatment.Structural optimizationwas achieved to counter specific pathogens,including Mycobacterium tuberculosis,in the Mycobacterium genus.One of the hit peptidomimetics was evaluated in a zebrafish-based aquatic infection model using Mycobacterium fortuitum and a mice tail infection model using Mycobacterium marinum,both revealing excellent in vivo performance. | Jianxue Wang Junfeng Song Xianhui Chen Rey-Ting Guo Yingjie Wang Guopu Huang Nan Zheng Peilei Hu Xinxin Feng Yugang Bai | 2022 | CCS Chemistry2022，4，11： | 0 |
