Abstract: Controlled assembly of nanoscale objects into complex and functional nanostructures or superstructures is of tremendous interest. However, effective fabrication of inorganic-nanoparticle superstructures (such as nanoparticles linked by metal/alloy phases) remains a difficult challenge. This talk will discuss scientific and technological issues related to scalable nanoparticle dispersion and self-assembly in metallic liquid systems to assemble metals and nanoparticles rationally into nanocomposite superstructures for novel functionalities. Metallic nanostructures with various novel architectures were successfully fabricated. A novel methodology for rapid control of material phase growth by nanoparticles is also discovered. The rapid control of phase growth stems from a remarkable diffusion blocking on the growing phase and the resistance against coagulation imposed by nanoparticles. Considering the growing availability of numerous types and sizes of nanoparticles, our approach provides a simple, general way for a rational design and scalable nanomanufacturing of functional nanostructures with desired architectures for exciting applications
