| 1 | Microstructure and Properties of W-Cu Alloys Prepared with Mechanically Activated Powder显示文摘W-15% Cu (mass fraction) alloys were sintered with mechanically activated powder in order to develop new preparing processes and improve properties of alloys. The microstructures of the activated powder and the sintered alloy were observed. Properties such as density were measured. The results show that through mechanical activation, the particle size of the powder becomes finer to sub-micron or nanometer level, some copper was soluble in tungsten, and high density W-Cu alloys can be obtained by mechanically activated powder for its action to the activation sintering. | Chengchang Jia, Xiuhu Guan, Xuekuan Su, Changheng Hou, Shimin Fan, Jun Zhao, Zizhang Xie (Material Science and Engineering School, University of Science and Technology Beijing, Beijing 100083, China) (Beijing Research Institute of Powder Metallurgy, Beiji | 2001 | Journal of University of Science and Technology Beijing2001，8，2： | 5 |

| 4 | Sierpiński triangles formed by molecules with linear backbones on Au(111)显示文摘Fractals play an important role in mathematics, aesthetic, science, and engineering. The representative Sierpinski-triangle fractals have been successfully constructed by V-shape molecules in experiments. The molecular Sierpinski triangles formed by molecules with linear backbones have been theoretically predicted but not experimentally discovered. To achieve this goal in the experiment, we used[1,1';4',1'';4'',1''']-quaterphenyl-3,40 0-dicarbonitrile molecules as building blocks and employed cobalt atoms as cements, then successfully obtained metal-organic Sierpinski triangles with an order up to 2 on the Au(111) surface. There are twenty-four types of three-fold coordination nodes formed between the metal atom and organic ligands via coordinate interactions. The coexistence of various nodes is responsible for that the highest order of Sierpinski triangles is limited to 2. | Xue Zhang Ruoning Li Na Li Gaochen Gu Yajie Zhang Shimin Hou Yongfeng Wang | 2018 | Chinese Chemical Letters2018，29，6： | 0 |
| 5 | Self-assembly of L-tryptophan on Cu(111) studied by low-temperature scanning tunneling microscopy显示文摘The self-assembly of L-tryptophan on Cu(111) is investigated by an ultrahigh vacuum scanning tunneling microscope(STM) at 4.4 K.When deposited onto the substrate at around 120 K with a coverage of 0.1 monolayer,molecular trimers,tetramers,hexamers,and chains coexist on Cu(111).Then almost all molecules self-assemble into chiral hexamers after being annealed at room temperature.When increasing molecular coverage to the full layer,a new type of chain is observed on the surface.Based on the high-resolution STM images at sub-molecular level,we suggest that the L-tryptophan molecules are present in neutral,zwitterionic or anionic states in these structures. | Qiang Xue Yajie Zhang Ruoning Li Chao Li Na Li Chenyang Yuan Shimin Hou Yongfeng Wang | 2019 | Chinese Chemical Letters2019，30，12： | 0 |
| 6 | Structure transformation from Sierpiński triangles to chains assisted by gas molecules显示文摘Reversible transformations between fractals and perio dic structures are of fundamental importance for understanding the formation mechanism of fractals.Currently,it is still a challenge to controllably achieve such a transformation.We investigate the effect of CO and CO_(2)molecules on Sierpiński triangles(STs)assembled from Fe atoms and 4,4″-dicyano-1,1′:3′,1″-terphenyl(C3PC)molecules on Au surfaces.Using scanning tunneling microscopy,we discover that the gas molecules induce a transition from STs into 1D chains.Based on density functional theory modeling,we propose that the atomistic mechanism involves the transformation of a stable 3-fold coordination Fe(C3PC)_(3)motif to Fe(C3PC)_(4)with an axially bonded CO molecule.CO_(2)causes the structural transformation through a molecular catassembly process. | Chao Li Zhen Xu Yajie Zhang Jie Li Na Xue Ruoning Li Mingjun Zhong Tianhao Wu Yifan Wang Na Li Ziyong Shen Shimin Hou Richard Berndt Yongfeng Wang Song Gao | 2023 | National Science Review2023，10，7： | 0 |
| 7 | Conductance of a single molecule C_(60)-SnPc heterojunction显示文摘Geometries of molecule-molecule interfaces strongly influence the current passing from one molecule to another. The contact conductance of molecule-molecule junctions which consist of fullerene and tin phthalocyanine molecules is investigated with a low-temperature scanning tunneling microscope. Two types of molecules are deposited onto Cu(111). Fullerene molecules are transferred to tips through controlled contact of STM tips on molecules. The molecule-molecule junctions are formed by approaching fullereneterminated tips to tin phthalocyanine molecules on Cu(111). Our experimental method can be extended to study the intermolecular charge transport of a range of molecular junctions. | Yifan Wang Mingjun Zhong Jie Li Hao Tang Richard Berndt Yajie Zhang Shimin Hou Yongfeng Wang | 2022 | Chinese Chemical Letters2022，33，2： | 0 |
