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."
since when is something that's bigger than a penny considered micro? i understand calling the paper nanopaper, because it's made out of nanofibers, but what's with the term 'microcup'?
if i'm not immortal, what's the point of living?
...te?
I'm still holding out for paper that can compute (probably by using rod logic) and then display the results on its surface. A little external memory interface and I can reduce my bookshelf to a harddrive and an 8 1/2 x 11 sheet of paper.
Philosophy.
I'll probably get modded -1, hippy for this but I've noticed that every time a great invention is made in the US, it is considered important that it can *also* be used for war. Whereas if something is invented in Europe, it's more in the lines of "it will help the environment and/or developing countries". What's up with the war fixation people?

... is *not a war use*. Its an environment improving use which happens to have some security implications, mostly for terrorism. It incidentally helps out developing countries more than it does the US, since we see have a strong national defense, no ongoing wars with nation-states, and a fairly good defense against terrorists, and developing nations are frequently 0 for 3.
Help poke pirates in the eyepatch, arr.
1. List the number of times chemical warfare agents have been employed. Classify as to whether the agents have been used by a government or by a terrorist organisation. In each case list the number of humans killed, injured, and the total amount of environmental damage done.
2. Using the results in 1. calculate the probability that conditional on a chemical agent being used, it was used by terrorists.
Bonus points: list usage by country, and calculate conditional probability as in 2, for different countries. Which country do you think is most likely to use a chemical agent in general, or in particular against humans.

At first I thought having the word 'Nano' in my nick sounded cool and high tech
Wow, you are really cool. You can have a job at my company, CompuGlobalHyperMegaNet. We can synergise together.
I hadn't thought much of the fear of various nano-dusts, etc. getting loose in the environment until my son broke one of those squishy pillows full of little beads open in his room. I encountered a pile of tiny little beads and others clinging to the wall and on every surface and finding their way into other rooms, etc. Even after a good vacuuming I threw my hands up and decided that these things would be around for awhile. 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?).
I'm mainly thinking about the pre-manufactured product's raw materials and the areas in and around where they might create this stuff.
