(1) ¡°The cubic morphology of fig. A shows an evident [100] orientation parallel to the electron beam (under the assumption that we are in presence of a single-crystal-like features, as the authors wrote), while, instead, the corresponding ED pattern is related by the authors to the zone axis [111].

¡°the lattice imaging  of figure clearly evidence the presence of polycrystalline features; the authors wrote that the ¡°hollow nanocrystals are not perfect single crystals but with highly oriented, single-crystal-like features¡±,  a significant part of the imaged area appears amorphous-like, but the quality of XRD patters evidence a scarce presence of amorphous materials and, as a consequence, this can be attributed to the presence of nanocrystallites with an orientation out of zone-axis
