4Taxonomic status of Chinese blue sheep(Pseudois nayaur):new evidence of a distinct subspecies显示文摘The blue sheep is an endemic species to the Qinghai-Tibet Plateau and surrounding regions.It has been regard­ed as having 2 subspecies:Pseudois nayaur nayaur and P.n.szechuanensis.However,such a classification re­mains controversial.Herein,we analyze 10 microsatellite loci and part of the mitochondrial control region for clarification in such taxonomic debates.We use samples from 168 individuals from 6 geographic populations covering almost all the distribution areas of the species in China to carry out comparisons.Phylogenetic trees derived from both the microsatellite and mitochondrial markers combined with the discriminant analysis of principal components(DAPC)and the STRUCTURE analysis reveal that the individuals in the Helan Moun­tains are well grouped with a distinct evolutionary lineage and are significantly different from the other popula­tions of P.n.szechuanensis according to Fst values,implying that this isolated population should be categorized as a valid subspecies;namely,Pseudois nayaur alashanicus.The isolation-by-distance(IBD)analysis shows a significant positive relationship between genetic and geographical distances among the populations.Hui GAO Nannan LI Yongjie HUANG Fujie QIAO Junle LI Zongzhi LI Yanxiang LI Zhenghuan WANG Liwei TENG Zhensheng LIU 2020Integrative Zoology2020,15,3:0
5Intriguing one-dimensional electronic behavior in emerging two-dimensional materials显示文摘Tomonaga-Luttinger liquid(TLL),a peculiar one-dimensional(1D)electronic behavior due to strong correlation,was first studied in 1D nanostructures and has attracted significant attention over the last several decades.With the rise of new two-dimensional(2D)quantum materials,1D nanostructures in 2D materials have provided a new platform with a well-defined configuration at the atomic scale for studying TLL electronic behavior.In this paper,we review the recent progress of TLL electronic features in emerging 2D materials embedded with various 1D nanostructures,including island edges,domain walls,and 1D moirépatterns.Specifically,novel physical phenomena,such as 1D edge states in 2D transition metal dichalcogenides(TMDs),helical TLL in 2D topological insulators(2DTI),and chiral TLL in 2D quantum Hall systems,are described and discussed at the nanoscale.We also analyze challenges and opportunities at the frontier of this research area.Xuan Song Teng Zhang Huixia Yang Hongyan Ji Jiatao Sun Liwei Liu Yeliang Wang Hongjun Gao 2021Nano Research2021,14,11:0
6Atomic tracking of thermally-driven structural evolution in 2D crystals:Case of NbSe_(2)显示文摘Advanced atomic tracking techniques play a critical role in characterizing structural evolution,elucidating fundamental mechanisms of exotic phenomena and tailoring delicate properties.Thermally driven structural modulation in 2D crystals,such as the charge density wave(CDW),often leads to intriguing quantum properties,making them a valuable platform for exploring fundamental physics and potential device applications.However,despite their significance,experimental studies addressing atomic tracking of thermally-driven structural evolution in 2D crystals have been limited.Herein,we utilize high-accuracy variable-temperature atomic tracking measurements with scanning tunneling microscopy(STM)to directly observe a series of structural transitions in a model 2D crystal,namely NbSe_(2).With the atomic tracking technique,we confirm the existence of the universal thermally-driven CDW transition hysteresis between the heating and cooling cycles.This transition hysteresis,characterized by a constant temperature offset,represents a new phenomenon of structural evolution.Our findings provide a feasible method to track CDW transitions at the atomic scale in 2D crystals,significantly contributing to a better understanding and the potential modulation of these materials'functions in nanodevices.Baofei Hou Teng Zhang Tingting Wang Hongyan Ji Huixia Yang Liangguang Jia Xu Han Jingsi Qiao Yu Zhang Liwei Liu Hong-Jun Gao Yeliang Wang 2024InfoMat2024,6,2:0

8Recent progress in 2D group-V elemental monolayers:fabrications and properties显示文摘A large number of two-dimensional(2D)monoelemental materials with huge application potentials have been developed,since graphene was reported as a monoelemental material with unique properties.As cousins of graphene,2D group-V elemental monolayers have gained tremendous interest due to their electronic properties with significant fundamental bandgap.In this review,we extensively summarize the latest theoretical and experimental progress in group-V monoelemental materials,including the latest fabrication methods,the properties and potential applications of these 2D monoelementals.We also give a perspective of the challenges and opportunities of 2D monoelemental group-V monolayer materials and related functional nanodevices.Peiwen Yuan Teng Zhang Jiatao Sun Liwei Liu Yugui Yao Yeliang Wang 2020Journal of Semiconductors2020,41,8:0
9Investigating molecular orbitals with submolecular precision on pristine sites and single atomic vacancies of monolayer h-BN显示文摘Understanding the influence of adsorption sites to the electronic properties of adsorbed molecules on two-dimensional(2D)ultrathin insulator is of essential importance for future organic-inorganic hybrid nanodevices.Here,the adsorption and electronic states of manganese phthalocyanine(MnPc)on a single layer of hexagonal boron nitride(h-BN)have been comprehensively studied by low-temperature scanning tunneling microscopy/spectroscopy and tight binding calculations.The frontier orbitals of the MnPc can change drastically by reversible manipulation of individual MnPc molecules onto and away from the single atomic vacancies at the h-BN surface.Particularly,the change of the molecular electronic configuration can be controlled depending on whether the atomic vacancy is below the metal center or the ligand of the MnPc.These findings give new insight into defect-engineering of the organic-inorganic hybrid nanodevices down to submolecular level.Liwei Liu Thomas Dienel Gino Günzburger Teng Zhang Zeping Huang Cong Wang Roland Widmer Wei Ji Yeliang Wang Oliver Gröning 2020Nano Research2020,13,8:0
10Morphological and phylogenetical analysis reveals that a new tapeworm species (Cestoda: Hymenolepididae) from whooper swan belongs to Cloacotaenia not Hymenolepis显示文摘During a helminthological study of waterfowl in China,a new species(Cloacotaenia cygnimorbus sp.nov.)of hymenolepidid cestodes(tapeworm)was found in the small intestine of whooper swan(Cygnus cygnus,Linnaeus,1758).The rudimentary rostellum and four unarmed muscular suckers,proglottids with distinct craspedote and three spherical testes were coincident with the characters of Cloacotaenia or Hymenolepis,but phylogenetic analysis of 28S rRNA and cox1 gene revealed that the new species is Cloacotaenia rather than Hymenolepis.Its morphology was also clearly diff erentiated from C.megalops in the arrangement of its testes in a triangle instead of in line and the cirrus unarmed rather than spined.Compared with C.megalops,the new species has more elongated neck,much larger mature proglottids and much smaller testes,cirrus sac,ovary,vitellarium and uterine proglottid.In addition,it infected the host intestine not the cloacae.Phylogenetic analysis of cox1 gene of the new species shows that it had a level of sequence variation(10.52–23.06%)with the sequences of C.megalops.The considerable morphological and molecular diff erences between those two parasites support C.cygnimorbus sp.nov.as a new species.Zhijun Hou Lei Han Ying Sun Dongdong Shen Zhiwei Peng Lixin Wang Qian Zhai Yanqiang Zhou Yaxian Lu Liwei Teng Hongliang Chai 2020Journal of Forestry Research2020,31,6:0
11Advances in probing single biomolecules: From DNA bases to glycans显示文摘Imaging biomolecules in real space is crucial for gaining a comprehensive understanding of the properties and functions of biological systems at the most fundamental level.Among the various imaging techniques available for biomolecules and their assembled nanostructures,scanning probe microscopy(SPM)provides a powerful and nondestructive imaging option.SPM is unique in visualizing intrinsically disordered biomolecules at the nanometer scale(e.g.,glycans).This review highlights recent achievements in studying biomolecules using SPM technique,focusing on DNA bases,amino acids,proteins,and glycans.The atomic-level analysis of biomolecules made possible by SPM allows for a more accurate definition of the local structure–property relationship.High-resolution SPM imaging of single biomolecules offers a new way to study basic processes of life at the molecular level.Baofei Hou Teng Zhang Huixia Yang Xu Han Liwei Liu Linfei Li Cesare Grazioli Xu Wu Nan Jiang Yeliang Wang 2023Interdisciplinary Materials2023,2,4:0
12Vanadium Defects Formation Mechanism in Undoped GaN Grown on Silicon显示文摘V defects in GaN layer grown on Si (111) using metalorganic chemical vapor deposition (MOCVD) were investigated by atomic force microscopy (AFM), plan-view transmission electron microscopy (TEM) and energy-dispersive X-ray spectrometer (EDS). Dislocations are the origination of V defects. Stress field around dislocations induce the concentration of C atoms, furthermore, slow growth rate on those {10-11} planes are suggested as being responsible for the initiation of V defects. The formation mechanism of V defects was discussed.Zhao Liwei Liu Caichi Teng Xiaoyun Hao Qiuyan Sun Shilong Zhang Wei 2006Journal of Rare Earths2006,24,z1:0
13Effect of Rapid Thermal Process on Oxygen Precipitates in Heavily Sb-Doped Silicon Wafer显示文摘Oxygen precipitates in heavily Sb-doped silicon after rapid thermal process (RTP) in Ar ambient were investigated by RTP at high temperature following annealing at 800 ℃ for 4 h and 1000 ℃ for 16 h. RTP temperature and cooling rates were changed from 1200 to 1260 ℃ and from 10 to 100 ℃·s-1, respectively. The experiment results show that high density of oxygen precipitates is observed in heavily Sb-doped wafer. It is found that the oxygen precipitates in heavily Sb-doped silicon are enhanced at high cooling rate.Sun Shilong Hao Qiuyan Zhao Liwei Teng Xiaoyun Liu Caichi Xu Yuesheng 2006Journal of Rare Earths2006,24,z1:0
