Microcups Made of Nanopaper

Roland Piquepaille writes "Researchers at the University of Arkansas have created long nanowires with titanium dioxide and assembled them into pieces of 'nanopaper.' This flexible paper can fold into 3D nanostructures such as tubes, bowls or cups. This kind of nanopaper could soon be used for applications such as bacteria filters, decomposition of pollutants and chemical warfare agents. But first the University needs to find industrial partners. Read more for additional details and some pictures of these microcups."

      If you really want the low down on that pledge of allegance crap, I'll let you in on it. It's a hold over when Eastern Europe was sending alot of people over here to be our brand new citizens. Ever wonder why the US is so hung up on English? Its sort of a related issue. Back then there wasn't any equal opp. laws or anything. Basically we made those new to the country feel like crap until they were good little US Citizens. Well what the hell is a US Citizen? First off you need to speak a US brand of English and get indoctrinated with our holidays and the pledge of allegance. Half the people that I've had an intellegent conversation on the topic admit that it is very Nazish, but it is the primary way we get those 2nd and 3rd generation new citizens to become "just like" everyone else. Who do you think pushes for that crap the most now a days? The families that remember coming here and think that the US is the best country on the planet. Remember there are reasons why alot of people don't like "public" education and the pledge of allegance is one of them.

    Titanium itself in pure, metallic form is very expensive, and is toxic to manufacture, agreed.

    But this paper is made of nanowires of titanium dioxide. Titanium is found in nature in the form of rutile. The rutile mineral mainly consists of titanium dioxide, and it's the third most abundant mineral in earth, after iron and aluminium in their natural form.

    I believe we can safely consider titanium dioxide (as opposed to pure titanium), as an almost unlimited resource, more abundant than forests and any form of living matter.

That, and taking note of the recent enviro-news on the persistence of Teflon related chemicals in the general environment and also around where it is made.

    I just hope they have the part figured out about how to control and contain this stuff before some folks end up with lungs full of titanium dioxide nano particles (I wonder what the disease will be called -- white lung?).
