Morphology is a key property of materials. Owing to their precise structure and morphology, crystals and nanocrystals provide excellent model systems for joint experimental and theoretical investigations into surface-related properties. Faceted polyhedral crystals and nanocrystals expose well-defined crystallographic planes depending on the synthesis method, which allow for thoughtful investigations into structure-reactivity relationships under practical conditions. This feature article introduces recent work, based on the combined use of experimental findings and first-principles calculations, to provide deeper knowledge of the electronic, structural, and energetic properties controlling the morphology and the transformation mechanisms of different metals and metal oxides: Ag, anatase TiO 2 , BaZrO 3 , and α-Ag 2 WO 4 . According to the Wulff theorem, the equilibrium shapes of these systems are obtained from the values of their respective surface energies. These investigations are useful to gain further understanding of how to achieve morphological control of complex three-dimensional crystals by tuning the ratio of the surface energy values of the different facets. This strategy allows the prediction of possible morphologies for a crystal and/or nanocrystal by controlling the relative values of surface energies.

“…2 In recent years, this material has attracted renewed interest because it was reported to be virtually inert to the attack from the BaO-CuO melt used for the growth of YBCO single-crystals. [3][4][5][6][7] Consequently, crucibles and other parts made of sintered BaZrO 3 can be utilized for the processing of high-purity single-crystals of high T c superconductor oxides. 5,6 New applications of BaZrO 3 are currently being investigated.…”

“…These are attractive for applications in the electro-ceramic industry and as special refractory materials [3][4][5][6]. Zirconium oxide has been used widely as an interferometry filter and high power laser mirror [7] while barium-zirconate finds its applications as deposition substrate and crucibles for the superconductor YBa 2 CuO 7 synthesis [8,9].…”
