Molecular Cage for the Capture of Large Cations
THE CHALLENGE
Cesium-137 is a radioactive isotope which is a common fission product of nuclear reactors around the world. After nuclear accidents, Cs is easily spread throughout the environment via the air and is extremely difficult to remove from the environment due to water-solubility. High levels of exposure to Cs-137 can lead to death, while lower...
