  text: "Branched nanocrystals (NCs) enable high atomic surface exposure within a
    crystalline network that provides avenues for charge transport. This combination
    of properties makes branched NCs particularly suitable for a range of applications
    where both interaction with the media and charge transport are involved. Herein
    we report on the colloidal synthesis of branched ceria NCs by means of a ligand-mediated
    overgrowth mechanism. In particular, the differential coverage of oleic acid as
    an X-type ligand at ceria facets with different atomic density, atomic coordination
    deficiency, and oxygen vacancy density resulted in a preferential growth in the
    [111] direction and thus in the formation of ceria octapods. Alcohols, through
    an esterification alcoholysis reaction, promoted faster growth rates that translated
    into nanostructures with higher geometrical complexity, increasing the branch
    aspect ratio and triggering the formation of side branches. On the other hand,
    the presence of water resulted in a significant reduction of the growth rate,
    decreasing the reaction yield and eliminating side branching, which we associate
    to a blocking of the surface reaction sites or a displacement of the alcoholysis
    reaction. Overall, adjusting the amounts of each chemical, well-defined branched
    ceria NCs with tuned number, thickness, and length of branches and with overall
    size ranging from 5 to 45 nm could be produced. We further demonstrate that such
    branched ceria NCs are able to provide higher surface areas and related oxygen
    storage capacities (OSC) than quasi-spherical NCs.\r\n\r\n"
