Platinum nanoparticles on SrTiO3 nanocuboids exhibit cube-on-cube epitaxy with the predicted Winterbottom shape. This thermodynamically stable configuration exposes different platinum surfaces than are exposed on polycrystalline supports.  The support surface controls the metal shape, thus by controlling the support surface stable, customized, high surface area, face-selective catalysts can be envisioned.
