3Room temperature ferromagnetism in ultra-thin van der Waals crystals of 1T-CrTe2显示文摘Although many emerging new phenomena have been unraveled in two dimensional(2D)materials with long-range spin orderings,the usually low critical temperature in van der Waals(vdW)magnetic material has thus far hindered the related practical applications.Here,we show that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the ultra-thin limit.It thus makes CrTe2 so far the only known exfoliated ultra-thin vdW magnets with intrinsic long-range magnetic ordering above room temperature.An in-plane room-temperature negative anisotropic magnetoresistance(AMR)was obtained in ultra-thin CrTe2 devices,with a sign change in the AMR at lower temperature,with−0.6%and+5%at 300 and 10 K,respectively.Our findings provide insights into magnetism in ultra-thin CrTe2,expanding the vdW crystals toolbox for future room-temperature spintronic applications.Xingdan Sun Wanying Li Xiao Wang Qi Sui Tongyao Zhang Zhi Wang Long Liu Da Li Shun Feng Siyu Zhong Hanwen Wang Vincent Bouchiat Manuel Nunez Regueiro Nicolas Rougemaille Johann Coraux Anike Purbawati Abdellali Hadj-Azzem Zhenhua Wang Baojuan Dong Xing Wu Teng Yang Guoqiang Yu Bingwu Wang Zheng Han Xiufeng Han Zhidong Zhang 2020Nano Research2020,13,12:6
4Luminescent single-molecule magnet of metallofullerene DyErScN@Ih-C80显示文摘Magneto-luminescent molecules have significant applications in data storage and quantum computing.However,design of these bi-functional molecules coupled with magnetic behavior and photoluminescence is still challenging.In this work,we report a metallofullerene DyErScN @In-C80 exhibiting single-molecule magnet (SMM) behavior and near-infrared emission.For DyErScN @Ih-C80,two functional lanthanide metal ions of Dy^3+(SMM function) and Er^3+(luminescent function) are integrated inside a fullerene cage using a trimetallic nitride template,and its structure has been unambiguously characterized by single-crystal X-ray diffraction.Magnetic measurements revealed that DyErScN @Ih-C80 behaves as a SMM with a blocking temperature up to 9 K resulting from the intramolecular magnetic interaction between Dy^3+ and Er^3+ ions.Moreover,DyErScN @In-C80 exhibits temperature-dependent near-infrared emission around 1.5 pm with multiple splitting peaks from Er^3+,which arises from the influence of Dy^3+ ion.This study provides a new strategy to synthesize new magneto-luminescent molecule materials.Mingzhe Nie Jin Xiong Chong Zhao Haibing Meng Kun Zhang Yibo Han Jie Li Bingwu Wang Lai Feng Chunru Wang Taishan Wang 2019Nano Research2019,12,7:2
5Static field induced magnetic relaxations in dinuclear lanthanide compounds of [phen_2Ln_2(HCOO)_4(HCOO)_(2-2x)(NO_3)_(2x)](1,Ln=Gd and x=0.52; 2, Ln=Er and x=0.90; phen=1,10-phenanthroline)显示文摘Two dinuclear lanthanide (Ln) complexes, formulated as [phen2Ln2(HCOO)4(HCOO)2-2x(NO3)2x](1, Ln=Gd and x=0.52; 2, Ln = Er and x = 0.90; phen = 1,10-phenanthroline), were synthesized and characterized. They are isostructural. The dinuclear molecule consists of two Ln 3+ bridged by four formate groups and chelated by phen and formate/nitrate ligands, and the Ln 3+ possesses a coordination environment of distorted tri-capped trigonal prism of LnO 7 N 2 . Both compounds behave as paramagnets between 2 and 300 K, but display two static field induced magnetic relaxation processes. One is slow and of spin-lattice type, and it results from the lifting of Kramer's degeneracy of the ground-states of both Gd 3+ and Er 3+ , and the other is fast, and it might be spin-spin type.LIU Bin WANG BingWu WANG ZheMing GAO Song 2012Science China Chemistry2012,55,6:2
6Lightweight fault localization combined with fault context to improve fault absolute rank显示文摘Lightweight fault localization(LFL), which outputs a list of suspicious program entities in descending order based on their likelihood to be a root fault, is a popular method used by programmers to assist them in debugging. However, owing to the nature of program structures, it is impossible for LFL to always rank the root faulty program entity at the top of a ranking list. Recently, Xia et al. noted in their study that programmers inspect the first top-K-ranked program entities outputted by an LFL tool in sequence. Therefore,it is of practical significance to further improve the absolute rank of those buggy programs by using LFL if the root fault is ranked higher. To solve this issue, we propose a new LFL combined with a fault context to improve the fault absolute rank. We conduct experiments in which we apply our proposed approach to seven Siemens benchmark programs. The results show that by combining the suspiciousness scores of program entities with their fault-context suspiciousness scores that are based on an LFL called Dstar, our approach can improve the fault absolute rank with an effectiveness rate of 35.7% for 129 faulty versions from the seven benchmark programs. It should be noted that our approach can obtain an average improvement of 65.18% for those improved programs to which LFL can be effectively applied, and that there were improvements to seven top-ranked root faults of buggy programs.Yong WANG Zhiqiu HUANG Yong LI Bingwu FANG 2017Science China(Information Sciences)2017,60,9:1

8Theoretical study on potential energy curves and spectroscopy properties of ground and low-lying excited electronic states of BrCl^+显示文摘The calculations on the potential energy curves and spectroscopic constants of the ground and low-lying excited states of BrCl+,one of the important molecular ions in environment science,have been performed by using the multireference configuration interaction method at high level of theory in quantum chemistry.Through analyses of the effects of the spin-orbit coupling interaction on the elec-tronic structures and spectroscopic properties,the multiconfiguration characteristic of the X2Π ground state and low-lying excited states was established.The spin-orbit coupling splitting energy of the X2 Π ground state was calculated to be 1814 cm-1,close to the experimental value 2070 cm-1.The spin-orbit coupling splitting energy of the 2Π(Ⅱ) exited state was predicted to be 766 cm-1.The transition dipole moments and Frank-Condon factors of the 3/2(Ⅲ)-X3/2 and 1/2(Ⅲ)-1/2(I) transitions were estimated,and the radiative lifetimes of the two transitions were briefly discussed.WANG MingWei WANG BingWu CHEN ZhiDa 2008Science China Chemistry2008,51,6:1

13Study on the covalence of Cu and chemical bonding in an inorganic fullerene-like molecule,[CuCl]_(20)[Cp^(*)FeP_(5)]_(12)[Cu-(CH_(3)CN)_(2)^(+)Cl^(-)]_(5),by a density functional approach显示文摘The electronic structure and chemical bonding in a recently synthesized inorganic fullerene-like molecule, {[CuCl]20[Cp*FeP5]12 [Cu(CH3CN)2+ Cl-]5}, has been studied by a density functional approach. Geometrical optimization of the three basic structural units of the molecule is performed with Amsterdam Density Functional Program. The results are in agreement with the experiment. Localized MO抯 obtained by Boys-Foster method give a clear picture of the chemical bonding in this molecule. The reason why CuCl can react with Cp*FeP5 in solvent CH3CN to form the fullerene-like molecule is explained in terms of the soft-hard Lewis acid base theory and a new concept of covalence.WANG Bingwu XU Guangxian CHEN Zhida 2004Science China Chemistry2004,47,2:0
14Bonding in [CuNRR′]4 type clusters显示文摘Many polynuclear Cu(I) compounds have been synthesized, but the problem whether there is direct or no direct Cu-Cu bonding in these compounds is not clear. The electronic structure of [CuNRR′]4 type clusters was investigated by using density functional methods. The results of geometrical optimization are in good agreement with experiment, and the localization of MO’s shows that there are four Cu-Cu s bonds to form the square Cu4 ring in addition to the four bridging Cu-N-Cu bonds. A concept of the covalence of molecular fragments is proposed to describe the bonding in these clusters.WANG Bingwu XU Guangxian CHEN Zhida 2004Science China Chemistry2004,47,3:0

16Ferromagnetic interactions in EO-azido-bridged binuclear transition metal(Ⅱ) systems: Syntheses, crystal structures and magnetostructural correlations显示文摘Three new isostructural binuclear transition metal complexes with azido ion and 1,2-bis(3-(pyridin-2-yl)-1H-pyrazol-1-yl)ethane (bppe), formulated as [M2(N3)2(bppe)2](ClO4)2 (M = Co, 1; Ni, 2; Cu, 3), were successfully synthesized. They were structurally and magnetically characterized. In 1-3, the double azido ions link two adjacent octahedral metal centers together in the end-to-on mode (EO), with the M-NEO-M angles of 99.41°, 100.24° and 99.80°, respectively. The co-ligand bppe acts as terminal ligand to saturate the remaining coordination sites. The magnetic properties of 1-3 have been investigated in the temperature range of 2-300 K. Fitting of the magnetic susceptibility data revealed the occurrence of the strong ferromagnetic interactions [J = 26.32 cm-1 (1), J = 38.23 cm-1 (2) and J = 139.83 cm-1 (3)]. Density functional theory calculations have been performed on 1-3 to provide a magneto-structural correlation of the ferromagnetic behavior.ZHANG ShiYuan WANG BingWu XU Na SHI Wei GAO Song CHENG Peng 2012中国科学:化学2012,42,6:0
17A Unique Layered Cu-formate Hydrate of Cu(HCOO)_(2)·1/3H_(2)O:Structures,Dehydration,and Thermal and Magnetic Properties显示文摘Anew layered Cu-formate hydrate of Cu(HCOO)2·1/3H2O is unique in its water content and the strongly waved (4,4) Cu-formate layers held by interlayer weak axial Cu-Oformate bonds and O-Hwater···Oformate hydrogen bonds. The crystal is in orthorhombic space group Pbcn, with cell parameters at 80 K:a=7.9777(2) Å, b=7.3656(2) Å, c=21.0317(5) Å(1 Å=10−1 nm), and V=1235.83(5) Å3. The Cu2+ ions are in the environments of a square pyramid and elongated octahedron, in a ratio of 1/2 within the structure. In the layer, Cu2+ ions are connected by anti-anti formates via short basal Cu-O bonds. The structure remains unchanged until the dehydration that produces the layered anhydrous β-Cu(HCOO)2, and the possible transformation mechanism, supported by diffraction evidence, is the reorganization of the Cu-Oformate bonds across the parent layers after dehydration. The two phases exhibit anisotropic thermal expansion behaviors closely relevant to the transverse thermal vibrations of the constituents. Cu(HCOO)2·1/3H2O is a 2-dimensional Heisenberg antiferromagnet, and exhibits a global spin-canted antiferromagnetism with the Néel temperature of 32.1 K. This is not only higher than that of the magnetically denser β-Cu(HCOO)2, but also the highest among the copper formate frameworks.FAN Huimin WANG Bingwu WANG Zheming GAO Song 2022Chemical Research in Chinese Universities2022,38,1:0

19Reprogramming plant specialized metabolism by manipulating protein kinases显示文摘Being sessile,plants have evolved sophisticated mechanisms to balance between growth and defense to survive in the harsh environment.The transition from growth to defense is commonly achieved by factors,such as protein kinases(PKs)and transcription factors,that initiate signal transduction and regulate specialized metabolism.Plants produce an array of lineage-specific specialized metabolites for chemical defense and stress tolerance.Some of these molecules are also used by humans as drugs.However,many of these defense-responsive metabolites are toxic to plant cells and inhibitory to growth and development.Plants have,thus,evolved complex regulatory networks to balance the accumulation of the toxic metabolites.Perception of external stimuli is a vital part of the regulatory network.Protein kinase-mediated signaling activates a series of defense responses by phosphorylating the target pro-teins and translating the stimulus into downstream cellular signaling.As biosynthesis of specialized metabolites is triggered when plants perceive stimuli,a possible connection between PKs and spe-cial ized meta bolism is well recognized.However,the roles of PKs in plant specialized metabolism have not received much attention until recently.Here,we summarize the recent advances in understanding PKs in plant specialized metabolism.We aim to highlight how the stimulatory signals are transduced,leading to the biosynthesis of corresponding metabolites.We discuss the post-translational regulation of specialized metabolism and provide insights into the mechanisms by which plants respond to the external signals.In addition,we propose possible strategies to increase the production of plant spe-cial ized metabolites in biotechnological applications using PKs.Ruiqing Lyu Sanjay K.Singh Yongliang Liu Barunava Patra Yan Zhou Bingwu Wang Sitakanta Pattanaik Ling Yuan 2021aBIOTECH2021,2,3:0
