14 DAY TRIAL // The molecules of the nanoworld have amazing properties like huge strength and electrical conductivity, but they can't do much on their own.
But they finally came together in Dallas, as a research team of the University of Texas has managed to link nanotubes, creating sheets about 2 inches wide and just 50 nanometers thick (that's 2,000 times thinner than the width of a human hair).250 acres of a solar sail made of nanosheet material would weigh less than 70 pounds, at this thickness. The researchers used multi-walled carbon nanotubes.
Starting with a "culture" of nanotubes chemically grown in a drum, the team devised the method to spin carbon nanotubes sheets with the rate of 20 yards a minute.
The sheets obviously enhanced the properties of individual nanotubes. They are transparent and function as light-emitting diodes, the same technology that has been used on Times Square's billboards.
They're very flexible, completing the range of displays that can easily be rolled or wrapped around a pole. On this basis, soon we'll might wear luminous clothing! The sheets also absorb microwaves, allowing them to become transparent heating elements and antennas for car windows.
Researchers say there are millions of other applications and they should come out in about three-to-five years. Most of the research was funded by the Department of Defense, which intends to use the results in improving aircraft industry and soldier's protective gear.
