Self-Cleaning Building Materials a Possible Weapon in Fight Against Smog自清洁建筑材料的一种可能的武器，打击烟雾

This technology sounds like a real boon to keeping cities clean:这项技术听起来像一个真正的福音，以保持城市的清洁： Self-Cleaning Building Materials a Possible Weapon in Fight Against Smog自清洁建筑材料的一种可能的武器，打击烟雾 , but I have to take issue with the writer’s exploitation of the term nanotechnology. ，但我必须考虑的问题，与作家的剥削一词的纳米技术。 He claims that “Research in the field has been made possible by the revolution in nanotechnology - science dedicated to building materials from the molecular level” but then goes on to say that, “The catalytic properties of titanium dioxide become active when it is applied in a very thin layer, or in microscopic particles.”他声称“领域的研究已经取得了可能是由革命的纳米技术-科学，致力于建设材料，从分子水平上” ，但接着就指出， “催化性能的钛白粉成为活跃的时候，这是适用于一个很薄层，或在微观粒子“ 。

So, is it nanotechnology or not?因此，这纳米技术是或不是？ Sounds like microtechnology to me!听起来像微给我！

Nanotechnology isn’t just a random term meaning really small stuff, it specifies particles in a specific size range.纳米技术不仅是一个随机长远的意义实在小的东西，它指定粒子在一个特定尺寸范围。 It’s sloppy use of prefixes like micro and nano that gets non-specialist journalists and readers into trouble and renders the newsprint they’re published in as so much grey goo.它的马虎使用的前缀一样，微型和纳米说，获得非专业新闻记者和读者麻烦，并使新闻纸，他们正在出版的，因为这么多灰色具。
