title: Octahedrality versus tetrahedrality in stoichiometric ceria nanoparticles.
abstract: We predict that tetrahedral Ce(n)O(2n) nanoparticles <2 nm in size become more stable than those experimentally observed at larger sizes with truncated octahedral morphologies, based on global optimisation and density functional calculations.
