Article ID: 1003-6326(2005)02-0306-04 Synthesis and characterization of single-crystalline alumina nanowires ZHAO Qing(赵 清), XU Xiang-yu(徐向宇), ZHANG Hong-zhou(张洪洲), CHEN Yao-feng(陈耀锋), XU Jun(徐 军), YU Da-peng(俞大鹏) (School of Physics, State Key Laboratory for Mesoscopic Physics, Peking University, Beijing 100871, China) Abstract: Alumina nanowires were synthesized on large-area......
Wenhua Road, Shenyang 110016, China摘 要:GaPO4-GaN coaxial nanowires were synthesized by two-step chemical vapor deposition method using H2 and NH3 as reactant gas in turn at 950℃. The morphology and microstructures of the GaPO4-GaN coaxial nanowires were studied by scanning elctron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy......
and ferromagnetic in Mn-doped anatase TiO2 nanowires LI Hong-mei(李红梅)1, 2, LIU Min(刘敏)1, 2, ZENG Yang-su(曾阳素)1, 2, HUANG Tong-cheng(黄同成)1, 2 1. Department of Information Engineering, Shaoyang University... of Mn-doped TiO2 nanowires (NWs) were prepared by hydrothermal method at the mole fraction of Mn changing from 0 to 12.0%. X-ray powder diffraction (XRD) analysis shows that all the samples have pure......
modification was characterized by nickel nanowires prepared in AAM. Scanning electron microscopy was used to characterize the topography and structure properties of the AAM and nickel nanowires... of the root structure. At the end of the modification, the barrier layer is thin enough to be passed by electrons. Hence, the direct electrodeposition of one-dimensional nanowires can be carried out......

Synthesis of single crystalline CdS nanowires with polyethylene glycol 400 as inducing template XU Guo-yue(徐国跃), WANG Han(王 函), CHENG Chuan-wei(程传伟), ZHANG Hai-qian(张海黔), CAO Jie-ming(曹洁明), JI... employed to synthesize single crystalline CdS nanowires in ethylenediamine medium at lower temperature (170 ℃) for 1－8 d. In this route, polyethylene glycol 400 (PEG400) was used as surfactant, which played......
to volume. the surface effects on the large deflection of nanowires were considered. Both geometric nonlinearity in finite deformation and surface effects at nanoscale were taken into account to analyze the bending of nanowires subjected to a concentrated force. For simply supported beams and clamped-clamped beams, the influence of surface effects and geometric nonlinearity were discussed in detail......
