Carbon nanotubes consist of tiny cylinders of carbon atoms one nanometer in diameter. "They are the strongest and stiffest materials yet discovered - hundreGeorgia Southern iPhone 4s Casesds oNHL Panthers iPhone 4 Casesf times stronger than steel but six times lighter - and their unique mechanical, electrical, thermal and transport properties present exciting oppRutgers iPhone 4s Casesortunities for research and development."

Thus far the production of carbon nanotubes have been measured iCollege Sports iPhone 4s Casesn grams per day using complex and expensive processes. The Australian researchers may well have found a way to up that production volume to a level that may, at last, make the material common enough to be usedCFL Redblacks iPhone 4s Cases on an industrial scale.

Non-biodegradable plastic shCincinnati iPhone 4s Casesopping bags have been a worry of environmentalists for a number of years. They tend to clog sewage systems and waterways and pose a hazard to wild life. While the bags are recyclable, with many super markets deploying bins for old plastic bags,MLB Angels Samsung Galaxy S4 i9500 Cases, a number of communities have banned them, forcing people to carry reusable cloth shopping bags.

The University of Adelaide's School of Chemical Engineering has developed a way to deal with two seemingly separate vexing problems,Pittsburgh Samsung Galaxy S4 i9500 Cases, what to do with plastic shopping bags and how to cheaply make carbon nanotubes, according to Phys.org.

Australian Scientists Turn Plastic Bags into Carbon Nanotubes

According to Discovery Magazine, carbon nanotubes can be used in a variety of applications, including biosensors,Utah iPhone 4 Cases computer chips, fuel cells, and drug delivery devices. If carbon nanotubes can be produced en masse they could be the killer app to buOregon iPhone 4 Casesild spaCFA Cats iPhone 4 Casesce elevators, immensely tall structures upon which people could travel as if by a vertical train from the Earth's surface to geo stationary orbit, cutting the cost of space travel by orders of magnitudeMLB Redsox iPhone 4 Cases.

"They used pieces of grocery plastic bags which were vaporised in a furnace to produce carbon layers that line the pores in the membrane to make the tiny cylinders (the carbon nanotubes)." Apparently, though,Pennsylvania Samsung Galaxy Note II N7100 Cases, any source of carbon would do for the process.
