Breakthrough made in nuclear-waste sequestration
Researchers at Northwestern University are developing a new method for removing radioactive materials from liquid nuclear waste.
The group of scientists led by Mercouri G. Kanatzidis, a Charles E. and Emma H. Morrison professor of Chemistry at Northwestern University, announced their breakthrough on Tuesday. The group's paper described the process metaphorically to how a Venus flytrap closes after absorbing a fly in its grip, while letting other objects pass by.
At the molecular level the radioactive ion cesium found in liquid nuclear waste passes through "holes" in a porous metal-sulfide material via an ion-exchange process. Meanwhile, harmless … Read more
