Carbon nanotubes (CNTs) have been shown to exhibit myriad chemical abilities. CNT materials are similar to activated carbon, but their regularized molecular structure has the potential for greater engineered control. An intriguing application is the removal and possible sequestration of radionuclides from nuclear plant waste streams. In this issue’s Viewpoint, researchers from three European research institutes overview the chemistry to date involving CNT materials interacting with radionuclides. In so doing, they sound a call to the environmental and materials research communities to further investigate the potential of functionalized CNTs and/or composites made from this novel substance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
