Nano “Light Bulb” Created- Smaller Than Bacteria

NanotechnologysoftechU.S. scientists have produced light-emitting nanofibers that are even smaller than most bacteria, or about the size of a virus.

I’ll explain how it’s done, just in case you have some old ruthenium tris-bipyridine lying around, and want to try out your new electrospinning machine. (Yeah, the one in your garage that your wife yelled at you for buying on Ebay last summer. You’ll show her!) Cornell University researchers researchers spun the fibers from a mixture of the metal complex ruthenium tris-bipyridine and polymer polyethylene oxide using a technique called electrospinning.

They found the fibers emitted orange light when excited by low voltage through micro-patterned electrodes- just like a tiny light bulb. Which means that this collaboration of experts in organic materials and nanofabrication, have developed the smallest organic light-emitting device ever created.

The scientists hope such a localized light source will be useful in sensing, microscopy, flat-panel displays and that other applications will eventually be discovered as well.

This research can be found in the journal Nano Letters. Posted by Rebecca Sato.


NanoArt -The World's Smallest Painting

Id1743Nanotechnology could soon create an art gallery full of art that nobody can see not even the artists who created it. Paintings, drawings, and sculptures so small that it is impossible to view with the naked eye. It s called Nanoart and it is proof that beauty is in the eye of the beholder (if you've got a good microscope!). 

Fish is the first of several works and commissions to be created in 2007.  Artist J Sha teamed with ARmark Authentication Technologies, LLC in Pennsylvania, to unveil what is believed to be the world s smallest piece of flat artwork, at a mere 40 microns tall with features as small as 250 nanometers, Fish is smaller than a spec of dust and 1/8th the width of a strand of hair.

George Clooney & Company to bring "Diamond Age" to SciFi Channel

Thediamondage_1 The Sci Fi Channel announced that George Clooney will be part of the creative team bringing the retro cyberpunk novel, The Diamond Age to the channel. Neal Stephenson will adapt the miniseries from his novel, which breaks new ground in a series that forecasts the coming nanotechnological revolution. Stephenson creates a future in which molecular machines can create any object or structure. National governments have broken down, leaving society divided into "tribes" along ethnic, cultural, and ideological lines, the most dynamic of which are the new-Victorian Atlanteans near the ancient city of Shanghai.

Stephenson's command of character and stylistic nuance has grown captivatingly stronger, and he now offers startling new ideas in virtually every paragraph. With breathtaking vision and insight, Stephenson establishes himself as not only a major voice in contemporary science fiction, but also a prophet of technology's future. Decades into the future, John Percival Hackworth, cultured nanotech engineer risks the censure of his neo-Victorian social class, or tribe, when he forges an illicit copy of a state-of-the-art interactive book called A Young Lady's Illustrated Primer for his daughter Fiona.

The primer is actually a super computer built with nanotechnology that was designed to educate Lord Finkle-McGraw's daughter. With the unprecedented power to single-handedly educate its reader, the primer is designed to shape the values and maintain the superiority of the dominant tribe by teaching young girls how to think for themselves in that stifling neo-Victorian society.
