neh..!! NASA is Multinational association... and many Myanmars are also there.. if u dont believe , ask that person.. LOL
out from ur sh-i-t hole..!! and Myanmars are running around the world..!! Got it..? Bangladeshi pig sh-i-t..!!
here some professors of Famous US universities.. enjoy it..

Scientists Build World's Smallest Superconductor

Scientists have created the world's smallest superconductor, made out of just four molecule-pairs and less than a nanometer wide. That's far smaller than the head of a pin - which stretches across a million nanometers - and more on the order of a DNA molecule, which is about
2 nanometers wide.
The invention, described in the journal
Nature Nanotechnology, provides the first evidence that nanoscale molecular superconducting wires can be fabricated, which could be used for nanoscale electronic devices and
energy applications.
Superconductive materials allow electrical currents to pass through with zero resistance, making them potentially useful to a wide variety of industries.
Lead author Saw-Wai Hla, a physics professor at Ohio University's Nanoscale and Quantum Phenomena Institute, explains that earlier it was almost impossible to make nanoscale interconnects using metallic conductors because the resistance increased as the size of wire becomes smaller. The nanowires become so hot that they can melt and destruct. That issue, Joule heating, has been a major barrier for
making nanoscale devices a reality, Hla says.
To get around that problem, Hla and his colleagues created molecules of an organic salt called (BETS)2-GaCl4 and placed it on a surface of silver. Then they had to bring the temperature of the molecules down to about 10 Kelvin (-442 degrees Fahrenheit). Using scanning tunneling spectroscopy, the scientists observed superconductivity in molecular chains of different lengths, raising the possibility that nanoscale electronic circuits could be produced at a larger scale. While consumer electronics obviously don't function at such extreme cold temperatures, the news that tiny superconductor wires can be fabricated is still expected to give a boost to the development of nanoscale electronics.
And there's yet more excitement in the world of nanotechnology, as two prototypes of motion-powered nanogenerators made of nano-sized parts were also revealed in
NatureNanotechnlogy(PDF).
