Material traps radioactive waste, could help nuclear cleanup http://apocadocs.com/s.pl?1270680249
It may be oversimplifying to suggest that the microscopic mechanism that Mercouri Kanatzidis and Nan Ding have developed resembles a roach motel of nuclear waste, where the ghastly undesirable checks in but doesn't check out. Kanatzidis prefers to call it a Venus flytrap.
Either way, the results are the same. The pinkish, powdery material the two researchers created traps cesium-137, a prevalent, stubborn radioactive contaminant. And trapping it could make clearing it from toxic sites immensely easier...Essentially, the sulfide framework acts as a "very tiny, tiny building with rooms," Kanatzidis said. The cesium enters the building, then bonds to the sulfide "walls" of the interior. At that point, the building begins "making all the doors and windows smaller so the cesium cannot get out," he added.
