The Cover shows a TEM
image of PtRhOx-SnO2 core-shell part
icles the authors were lucky to collect dur
ing TEM measurements, rather than the usual near-spher
ical shape. In the
ir Commun
icat
ion, G. Yang et al. not only show that the
image of a perfectly heart-shaped catalyst part
icle
is eye-catch
ing, but also an
ideal showcase for the comb
