Nanotechnology: answer to air pollution?

Abstract:
The emerging field of nanotechnology could provide a solution to the soaring air pollution caused by automobile emissions worldwide, scientists say.

Research shows that nano-treatment of engines can cut down toxic gas emissions by up to 90 per cent, Prof J Narayan of North Carolina State University told PTI here.

"Use of nanotechnology based systems increases the rate of pre-emission carbon trapping considerably, which is the main constituent of carbon dioxide," explains Narayan. "Thus, it causes cleaner emissions," he added.

Nanotechnology, a very important branch of applied science that deals with matters on atomic and molecular scale, "has a considerable role to play in improvement of energy efficiency," Director of Ansal Institute of Technology M P Singh said.
