Formation of Metallic Nanomaterials by Controlled Atomic Accumulation and Their Characterizations

已经建立了控制原子扩散和扩散原子积累的机制的科学基础，并在理想的位置成功地形成了各种具有所需几何形状的金属纳米材料，如纳米线、纳米线圈、纳米管和纳米球等。对制备的纳米材料的力学、电学和电磁性能进行了研究。并针对其应用前景，开发了焊接、切割、弯曲等改性技术，为其规模化生产奠定了技术基础。

The scientific bases of the mechanisms for controlling the atomic diffusion as well as the accumulation of diffused atoms have been established, and various kinds of metallic nanomaterials such as nanowire, nanocoil, nanotube and nanoball with desired geometries, i. e., diameter, length and shape, etc., have been successfully formed at a desired location of interest. The mechanical, electrical and electromagnetic properties of the fabricated nanomaterials were investigated. Moreover for their future applications, modification technologies, such as welding, cutting and bending, and the basis of their mass production technique were developed.
