ABSTRACT
This article reports that according to U.S. researchers nanoparticles could be pumped into a burning building to clear poisonous smoke. Ronaldo Maghirang, project leader on smoke reduction research at Kansas State University, said the nanoparticles cling to the smoke particles, causing them to plummet to the ground. The team compared a range of commercially available particles, including sodium bicarbonate used in fire extinguishers and calcium hydroxide, which was effective but proved toxic. Another group is working in parallel to determine whether the nanoparticles could pose a later health risk if dispersed into the environment.
