Nano Light-Emitting Fibers In the Lab
moscowde writes "Researchers at Cornell University have created a so-called Nano-Lamp — a microscopic collection of light-emitting fibers with dimensions of only a few hundred nanometers. The fibers are made of a polymer spiked with ruthenium molecules in a process dubbed 'electrospinning.' The bright spots on the fibers are smaller than the wavelength of the light they emit. The nanofiber glows bright orange when exposed to an electric field and can be seen in the dark with the naked eye. A professor at Princeton University called this 'a breakthrough in the way nanosize light sources are made.' Since the nanofibers are flexible, they could potentially be used in clothing or bendable computer displays."

That's interesting...
Anyway, next-gen computer displays, anyone?
Four questions about bendable screens (which I love the idea of. I would have to update my laptop if they come out with those.) I am not a scientist, so I have no clue what the answers could be.
Your ad here. Ask me how!
Mark me on this. These fibers will be included in hair weaves and seen frequently in clubs.

i want to see curved displays - like a giant earth globe/sphere that is a display, or a mounted movable sphere you can be inside of, with your head at the center that displays inward to the viewer. you run around inside and the globe spins, moving you in a virtual environment - 3D WOW fun!
And then again, I'm not.
Can you imagine the uses for bendable computer displays? Some would be amazing. You could have a roll-up monitor in your pocket like you see in science fiction movies.
Or there could be people wearing clothing made out of them covered in advertisements... That's what I'm afraid of. Imagine walking down the street and you see something bright coming towards you. You squint your eyes. As it gets close, you can make out the words emblazoned all over the body like a battle flag.

I was telling an engineer friend of mine that if she could make clothes that had dynamic writing on them, she would make a fortune. Imagine, a t-shirt that says: GOT ROOT? at one point, and GOT ROOT! at another ;-) Or a tshirt with a short animation playing across it. Instead of riding' spinnaz', rappers could make songs about wearin' scrollaz'!

Put these right on the CPU and watch the ping drop and bandwidth increase.

Seems like it uses a lot of power...100v through a 250 nm fiber...no wonder it glows!
Nano led-arrays sound way cooler, to me
Somehow I don't think this will ever be a fashion statement.
It must have been something you assimilated. . . .

I'm still amazed this guy was stupid enough to do a side view in the leotard.....he's a leotard reotard...
I guess... if you want clothing that glows faintly orange in the dark...

What is new about this? Electrons emit light too; they're 1.0 × 10^-6 nm in diameter, over a million times smaller?
Anyone have a link to something a little more in depth than the blog post that is TFA that explains this a little better?
Right, because the one thing we've all been craving is 394 million dpi displays. :-P
1) take any fluorescent or electro luminescent material
2) put down a drop of it smaller than a wavelength
3) excite it with UV light or electrons
4) viola and arbitrarily small light source much smaller than a wavelength
Coat the tip of any nano fiber this way and it's still true.
Wha's the big deal? Atoms emit light from source smaller than a wavelength all the time.
What's tricky is that short of negative index materials you can't propagate light or confine light beyond the near field in areas less than the wavelength squared (or thereabouts). This is not to say that light guides can't be smaller than the wavelength because some guides don't actually confine the light inside.
TFA does not give me enough info to see if they are beating this last effect.
Some drink at the fountain of knowledge. Others just gargle.
The fibers will be woven into ribbons and tied in the manes of ponies. Lots and lots of ponies. OMG, PONIES, you insensitive clods!!!

They actually used ruthenium(II) tris(bipyridine)/polyethylene oxide mixtures.
Yeah, like Altavista was doing until they were forced to copy the Google clean visual because people have already become saturated with advertisements.
New larger road-side displays of the Mooninites giving the finger will be distributed very, very soon.
Even more advertisements every where i walk. Great going guys.
