Modifying the molecules Molecules called triazines are capable of removing (or extracting) these harmful elements from spent nuclear fuel in a highly selective way. The researchers changed the size of the aliphatic rings in the established benchmark molecules from 6-membered rings to 5-membered rings.
"The findings are significant as they could allow better molecules to be designed in a more rational way, rather than simply by trial and error.”
