■ AbstractThe rapid development of nanoscience for the last two decades has been largely sustained by knowledge coming from traditional research areas including inorganic chemistry and materials science. Nowadays, as nanoscience becomes a mature field, nonclassical phenomena which are unique to nanoscale materials are attracting an increasing amount of interest. In this seminar, formation mechanisms of nanomaterials that are not consistent with the classical theories are discussed with selected examples: 

i) Unlike the traditional crystallization theory, there are increasing evidence of nonclassical multistep nucleation of nanoparticles through metastable structures bridging molecules and crystalline solid. They make the reaction system far deviated from the one predicted by classical nucleation theory, which assumes a single-step transition from solute to solid. 

ii) The formation of heterostructured nanoparticles is a combination of two well-known phenomena, heteroepitaxy and heterogeneous nucleation. However, on the surface of nanometer-sized seed nanoparticles, they show unexpected interactions with each other affecting lattice strain, nucleation kinetics, and morphology of the nanoparticles. 

iii) Mechanism study on the formation of doped nanoparticles reveals that doping in nanometer scale can be substantially different from the bulk counterpart. In conclusion, study of nanochemistry will not only contribute to extend our knowledge to cover the forbidden area in between molecular chemistry and solid state science, but also form the basis of design principles for the systematic synthesis of complex nanostructures with improved performance.
