48_01/2009Cover Picture: Shape-Controlled Synthesis of Metal Nanocrystals: Simple Chemistry Meets Complex Physics? (Angew. Chem. Int. Ed. 1/2009)

Crystals as you like them: The last decade has witnessed the successful synthesis of metal nanocrystals in a rich variety of shapes. As a zero-order approach, a typical synthesis can be divided into three distinct stages: nucleation, evolution of nuclei into seeds, and growth of seeds into nanocrystals. As illustrated in the cover picture and discussed by Y. Xia et al. in their Review on page 60 ff., the final shape of a nanocrystal is determined primarily by the internal structure of the seed and the binding of the capping agent.
