Graphene oxide soaks up radioactive waste: U.S., Russian researchers collaborate on solution to toxic groundwater woes - Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers in the United States and Russia have found. The discovery could be a boon in the cleanup of contaminated sites like the Fukushima nuclear plants damaged by the 2011 earthquake and tsunami. It could also cut the cost of hydraulic fracturing ("fracking") for oil and gas recovery and help reboot American mining of rare earth metals.(10.1039/C2CP44593J)
