A nano-sized sponge made of electrons

During chemical reactions, ceria nanoparticles behave in a completely different way than previously thought: the electrons absorbed and released during the reaction are not bound to individual atoms but, like a cloud, distribute themselves over the whole nanoparticle. Scientists have found far-reaching consequences for optimizing the current and future use of these nanoparticles and for assessing the limits of their safe use.
