Note: Indian newspapers* are pretty careless about phrases like "world's thinnest" or "world's strongest", so take that part with a grain of salt. They often just mean mind-bogglingly thin, and don't mean it as an absolute factual statement. For eg., there seems to be older news[1][2] from 2007 where European researchers created graphene sheets of single atom thickness, at 0.35 nm.<p>(*of course this probably also applies to other countries' media to varying degrees, I'm just most familiar with this tendency here in India.)<p>Edit: The actual journal paper[3] doesn't mention the exact thickness of the nanosheets, but it also mentions nanoflakes and nanograins and other forms of the material, and those seem to be measured at "~6-7 nm". And from what I can tell, the actual nanosheets vary in thickness and are not this utterly uniform sheets I had conjured up in mind.<p>Pretty fascinating stuff, there's apparently a 'NanoArtography' competition too [4], and this group won the People's Choice award with "The flower and the bud":<p>> The image[5] represents magnesium and boron based nanostructures synthesized by a bottom-up approach being developed by our research group. [...] One of the clusters resembles a full grown flower and another cluster nearby it resembles a bud in the process of growing. The clusters seem connected by a stalk like structure. This nanoflower and nanobud was imaged using a Scanning electron microscope. Image width is 0.009 mm.<p>[1] <a href="http://www.foxnews.com/story/2007/03/01/scientists-develop-thinnest-material-ever-one-atom-thick.html" rel="nofollow">http://www.foxnews.com/story/2007/03/01/scientists-develop-t...</a>
