The synthesis of precise nanomaterials is crucial to both advance fundamental knowledge and to fully exploit their peculiar properties. Basic studies on the synthesis of colloidal materials are needed in order to improve current methods for making these precise building blocks. In this talk, recent results on the use of in-situ scattering techniques to study these processes will be presented. Novel insights into the role of surfactants and reaction conditions for the growth of precise metallic nanocrystals will be provided. Furthermore, the discovery of crystallization processes occurring during the synthesis process will be discussed, with the opportunity to engineer not only the structure of individual nanocrystals, but also to extend this control to self-assembled materials such as superlattices. This increased knowledge, corroborated by thermodynamic models, is utilized to tune and control the size and composition of colloidal nanocrystals, which are important parameters in their applications in many areas, for example in catalysis.
