Nine Inch Nanotubes Almost
plasticpixel writes "EE Times is reporting that researchers have demonstrated the world's longest nanotubes at 8 inches. The feat was accomplished by adding hydrogen and sulfer compounds during the process to create these super long and non-tangled tubes. Super long nanotubes have been one of the holy grails in this area of science."
really goes great with those mind control electrodes.
2 for 2!
Researchers at Rensselaer Polytechnic Institute have demonstrated the world's longest carbon nanotubes. Using chemical vapor deposition (CVD), the standard process for semiconductor fabrication, researchers discovered that adding hydrogen and sulfur compounds produced high yields of wires as long as eight inches.
According to Rensselaer associate professor Pulickel Ajayan, this marked the first time a process has been shown to grow nanotubes long enough to serve as bus interconnects across or even between chips. Ajayan was assisted by his graduate student, Bingqing Wei from Tsinghua University in Beijing.
Since their discovery in 1991, carbon nanotubes have held the promise of supporting near-superconducting speeds at room temperature. Carbon nanotubes also exhibit quantum effects when doped with impurities. Their first application will probably be as the channel in tiny field-effect transistors.
Unfortunately, other attempts to use CVD to grow long nanotubes have resulted in a tangled mess, since the tiny structures tend to clump together in a manner similar to the way protein strands fold.
Ajayan's innovation was to add a sulfur compound in the presence of hydrogen, resulting in untangled nanowires as long as eight inches. According to Wei, the process could be adopted universally as an easier alternative to create nanotube material in general.

8 inches!
9 inches!
10 inches!
They're good men, but they still measure in inches.
The living have better things to do than to continue hating the dead.
...to have a 9 inch nanotube! ;-)

Nine Inch Nails
heh must have been intentional. i supose somone running slashdot has a sense of humor.

it's diameter that counts, not size !
Google passes Turing test : see my journal
If we would use them as Nails? Nine Inch Nails are very popular.

Does anyone know how much equipement you need to create these carbon nanotubes. I talde with one of my teacher, who was trying to find a new utility to my school's old white room. But couldn't because of budgetary problems. Now if most of the equipement is already there and there is only a few things to add to create nanotubes, that could be a great idea. Maybe we could be among the first to build a carbon nanotube based transistor and then chip and then who knows ..
Damn! That's sounds really fast!
You'd think the EE Times would hire reporters with some tech skills.
Coated with phosphors for extremely high resolution displays? High enough to create holographic display systems?
Take one nanometer thick sheet of electrically conductive cloth. Place near hard electrically conductive surface. Impress modulated voltage. Ultrasonic imagining might get a real boost.
Take a mm thick bundle of fibers and connect both ends to actuators. Impress high voltage.
And that's just mundane stuff.
Think of the electro-optical properties of spacing nanotubes fixed distances apart. Linear non-refractive optics. Interesting antenna, pulse shaping properties from microwave to ultraviolet. Might even be able to make ultraviolet lazers with these things.
Sure hope nobody forgets and takes a picture with a flash.
Ok nine inches is a start, but it's still a long way from orbit.

Condoms.
The nanotubes will be tightly weaved into the required shape and covered with latex. They will never break although some will claim that the latex burned off. It'll be much easier to create the stubs and ribbed versions as well.
The only problem will come from the p0rn industry...actors will have thier d^$#s burned off due to the camera flash when taking promotional stills.
