Nanotech Breakthrough

In today's edition of the journal Science, however, scientists from the University of Texas and Australia's Commonwealth Scientific and Industrial Research Organization report the creation of industry-ready sheets of materials made from nanotubes. Nanotubes are tiny carbon tubes with remarkable strength that are only a few times wider than atoms. They can also act as the semiconductors found in modern electronics.
"This is fundamentally a new material," says team leader Ray Baughman of the University of Texas at Dallas in Richardson.The team has developed an automated process that produced 2-3/4-inch-wide strips of nanotubes at a rate of about 47 feet per minute. Other methods take much longer to create nanotube sheets.
- Self-supporting, transparent and stronger than steel or high-strength plastics, the sheets are flexible and can be heated to emit light.
- A square mile of the thinnest sheets, about 2-millionths-of-an-inch thick, would weigh only about 170 pounds.
- In lab tests, the sheets demonstrated solar cell capabilities, using sunlight to produce electricity.
