Iron nanoparticles snatch uranium | Science News
Using wee balls of iron, scientists can catch radioactive fuel — hook, line and sinker.
In liquid, iron nanoparticles quickly lure and encase uranium, which researchers can then reel in with a simple magnet. The method, reported online February 17 in the Journal of the American Chemical Society, could be used to sop up radioactive spills or to fish for fuel for nuclear power plants.
