What happens to a metal alloy when it is mechanically stretched to form a nanowire that contains just a few atoms? Can a chain of atoms still be an alloy?
[quote]Research into nanostructured materials frequently relates to pure substances. This contrasts with industrial applications, where chemical doping or alloying is often used to enhance the electrical or mechanical properties of materials1. However, the controlled preparation of doped nanomaterials has been much more difficult than expected because the increased surface-area-to-volume ratio can, for instance, lead to the expulsion of impurities (self-purification)2. For nanostructured alloys, the influence of growth methods and the atomic structure on self-purification is still open to investigation2, 3. Here, we explore, experimentally and with molecular dynamics simulations, to what extent alloying persists in the limit that a binary metal is mechanically stretched to a linear chain of atoms. Our results reveal a gradual evolution of the arrangement of the different atomic elements in the narrowest region of the chain, where impurities may be expelled to the surface or enclosed during elongation.[/quote]

High-resolution measurements with atomic force microscopes have revealed that DNA molecules are a lot more flexible on length scales of 5–10 nm than was previously thought.

Cerium oxide nanoparticles could be used to treat eye disorders and other diseases by neutralizing the effects of reactive oxygen intermediates.

[b]4. Nanotube growth[/b] [img]http://www.nature.com/nnano/images/homepage/nnano.2006.95.jpg[/img]
Article by [i]Yamada[/i] et al.
Engineered iron catalysts can be used to grow double-walled nanotubes, which self-organize into vertically aligned ‘forests’ that can reach more than 2 mm in height.

国内可以下载吗?

国内好像还没有买这个数据库哭吧?中科院内好像不能下载啊!:(

我想看全文

不错。
我想看nanotube growth文章的全文,不知道那儿可以看到。
