| 1 | Synthesis of trans-bis(glycin- ato) copper(II) complex nanorods by room tempera- ture solid-state reaction显示文摘Trans-[Cu(glyo)2(H2O)] nanoparticles with average diameters about 20—30 nm were prepared by one- step room temperature solid-state reaction. Trans-[Cu(glyo)2] nanorods with diameters ranging from 100 to 150 nm and lengths up to several ìm were also prepared by one-step room temperature solid-state reaction in the presence of a suitable nonionic surfactant PEG400. The chemical composi- tion and structural features of the products were investigated by elemental analyses, XRD, TG, SEM and TEM, respec- tively. The mechanisms of formation were also discussed. | WANGLi LIULang JIADianzeng CAOYali XINXinquan | 2005 | Chinese Science Bulletin2005，50，8： | 5 |
| 2 | Formation, structure and properties of GeC_(n)^(±) and Ge_(2)C_(n)^(±) binary clusters显示文摘The binary cluster ions Ge2Cn+/Ge2Cn? and GeCn+ have been produced by laser ablation. The parity ef- fect is present in the negative ions Ge2Cn?, though it is not very prominent. While the experiments tell that the parity effect is totally not shown in the positive ions Ge2Cn+. An extensive theoretical investigation on GeCn/GeCn+/GeCn?(n = 1?10) and Ge2Cn/Ge2Cn+/Ge2Cn?(n = 1?9) has been carried out by density functional theory at B3LPY level. The calcula- tion shows that the low-lying states of GeCn/GeCn+/GeCn?(n = 1?10) and Ge2Cn/Ge2Cn+/Ge2Cn? (n = 1?9) are linear structure with germanium atoms locating at terminals respectively. The electronic distributions, ionization potential (IPad), elec- tron affinity (EA) and increasing bonding energy reveal that the parity effect of neutral species is much stronger than that of ions, which is attributed to the valence π-electrons. It is explained that the differences between experiments and cal- culations are due to the kinetic factor in the formation of Ge2Cn±. | CAOYali LIGuoliang TANGZichao | 2005 | Chinese Science Bulletin2005，50，9： | 0 |
