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."
Titanium dioxide, nanowires, nanopapers... just the stolen ingredients from my racoon sex doll.
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?
Finaly there will be a drink at Starbucks that I can afford. One grande ..uh,uh, Nano Latte please.
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.
Now all they need is a nano-dispenser because those teeny-tiny dixie cups at the watercooler just arent small enough.
I thought a microcup is what your girlfriend has...

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?

Finally, with titanium of this thickness, a condom that can handle my workload is possible.
I can't wait to wipe my ass with titanium nano-fibers!
This is a real concern actually, the western world is wiping their asses with the rainforrests.
Perhaps this softof "paper" will prove to be a plausable alternative? I really hope so...
I think we can keep recursing like this until someone returns 1
... 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.

It's not offtopic, dumbass. It's orthogonal.
Does that mean I can get a reusable condom? That would lower my daily costs dramatically..
It takes a thousand sheets of nanopaper to make only one microcup.
What a waste of paper.
If you have something the size of a hard drive, why does the computing have to be done in the paper. You have that huge box to do the computing in. Of course what you really want is the paper to have a tranciever, and a sensor so that you can tell it when to change the display, even if the computing is done over on the bookshelf.
At first I thought having the word 'Nano' in my nick sounded cool and high tech, but now that they're attaching it to words like 'cups' I'm having second thoughts.
"Derp de derp."
...another peice to the grand goal of widespread nanomachine usage. As a supporter in the continued advancement of all reasonably sane technology I find this to be a good thing.
With added padding for those who feel inadequate with a microcup...
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.
As a reference, you can use the following material: http://en.wikipedia.org/wiki/Chemical_Warfare
From TFA: University of Arkansas researchers have created assemblies of nanowires that show potential in applications such as armor, flame-retardant fabric, bacteria filters, oil cracking, controlled drug release, decomposition of pollutants and chemical warfare agents.
The usefulness of the material extends to the decomposition of chemical agents, not their creation. The sentence could be a little clearer.
So, wait, nanowires join together to make nanopaper which in turn is made into microcups. What the heck's going on? How do you make nanocups?? From femtowires????
Oh, *I* get it. They probably made nanocups, and then they were like, hey, what's even more cool than nanotechnology? HUGE nanotechnology, that's what! So they tried to build the biggest nanotechnology they could -- the microcup!
Only now it's NOT NANO ANY MORE, is it? You scientists think you're so smart, but you're just mean to rabbits.
Whence? Hence. Whither? Thither.
hmmm, i dunno about yous lot but the fact that it can be heated to 700 degrees celsius and 'remain stable' is a useful property for something that resembles paper, no?

Clean cup, clean cup. Move down!
It must be terribly hard to take one's tea at the nano scale. I mean, those tiny espresso cups are classy, but this is ridiculous!
So where is my promised paperless society????
I've had a hanckerin' for a monosword for years.
I'm missing the really, really small picture.
I never spellcheck and I freely admit it. Save your karma for more worthwhile "lol erorrs" replies
Now, this may come as a shock to you, but the iPod Nano is not actually NOT 1e10^-9 times the size of a regular iPod...and nobody gives a damn.
This flexible paper can fold into 3D nanostructures..."
Sure sure sure... but can it be folded more than seven times??

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.
These microcups may mean the end of teetotalling as we know it.

Hey pal, this isn't a pleasantforest, so don't waste my time with pleasantries!
The term "nanotechnology" is supposed to refer to the construction of machines so small, their component sizes are measured in nanometers. Similarly, "microtechnology" refers to tiny machines whose component sizes are measured in micrometers.
However, in the referenced article, the so-called "3D nanostructures" are described as: "These three-dimensional hollow objects can be manipulated by hand and trimmed with scissors". The photos show simple hollow objects that are all larger than a U.S. penny. The component sizes would be measured in millimeters. So they at best are millicups, not microcups.
Nanotechnology refers to the construction of machines a million times smaller than this. You can't manipulate a nano-machine component by hand and trim it with a pair of scissors.
This is another example of researchers misusing the prefix "nano-" to describe work that is not even remotely close to nano-technology. Why is this important? This article would never have made the Slashdot front page if the prefix "nano" had not been used.

I have written a truly remarkable program which this sig is too small to contain.
From TFA: University of Arkansas researchers have created assemblies of nanowires that show potential in applications such as armor, flame-retardant fabric, bacteria filters, oil cracking, controlled drug release, decomposition of pollutants and chemical warfare agents.
Unfortunately, according to the AP style rules (which any public release that someone is getting paid to produce should be following), "the decomposition of pollutants and chemical warfare agents" would be two seperate items. Even if you ignored the style rules, it's basic grammar that the last item in a list of items is preceeded by the word 'and'. If they were indeed both one item, it would read more like:
University of Arkansas researchers have created assemblies of nanowires that show potential in applications such as armor, flame-retardant fabric, bacteria filters, oil cracking, controlled drug release and the decomposition of pollutants and chemical warfare agents.
Regardless it is a poor word choice and could use some official clarification.
Well I can make a nanohat, or a nanobroach, or a nanopterodactyl...
Or the awaited ingredients for the world's tiniest cellphone, ringing in a movie theater just for you, by the quadrillion - and impossible to grab and turn off.

Starbucks has just started using these nanocups. The smaller size coffee costs $6.

IIRC the little cars were just over a penny in size.

Not saying it's valid, just that is since when

Like America discovering something that protects us from the effects of WMDs isn't the scariest fucking concept to ever hit the planet.
Further, the material can be cast into different three-dimensional shapes, with different functions. The researchers have created tubes, bowls and cups using this process. These three-dimensional hollow objects can be manipulated by hand and trimmed with scissors, the researchers report.
In other words, just like regular paper, you can fold it and trim it with scissors, making interesting origami. It's a pet peeve of mine that researchers feel they have to talk about ordinary things in such obscure ways.
Having gotten my master's degree, I've come to the conclusion that much of the work in academia consists of the following steps repeated over and over again by different people:
1) Spend several months studing an agonizingly complicated research paper, only to realize that 99% of the paper is intentional obfuscation of obvious things, with the remaining 1% being the actual novel idea that improves some technique.
2) Spend a week or two finding another novel idea that leads to some overall improvement of the technique. This improvement could also be stated in a sentence or two, but isn't.
3) Spend several months writing filler material stating obvious things in highly complicated language. Combine with the miniscule morsel of scientific knowledge created in step 2, in a ratio of 100 to 1, then publish as a paper or thesis.
Don't get me wrong. This research is very cool, and I'm sure coming up with carbon-nanotube paper took more than a few weeks of research, but the part about "three-dimensional hollow objects" really bugs me.
