Interesting. From the title I thought this was describing an electrochemical process to reduce uranium oxides into uranium metal, but the paper is actually talking about an electrochemically switched mechanism to easily capture UO2 particles in a solution and then easily release them on demand later. This ability is very useful for nuclear waste processing, environmental cleanup, and maybe mineral extraction, rather than metal production as I originally thought.
