Savvy Sieve: Carbon nanotubes filter petroleum, polluted water

By Alexandra Goho, 15:51 PM April 15, 2008

Bridging the gap between the nanoworld and the macroworld, researchers have created a membrane out of carbon nanotubes and demonstrated its potential for filtering petroleum and treating contaminated drinking water.

Scientists have long valued carbon nanotubes for their high strength and thermal properties (SN: 6/5/04, p. 363: Available to subscribers at, yet it's been a challenge to assemble nanotubes into useful materials large enough for ...
