Nanoparticles as Models for Atoms and Molecules

Nanoparticles have played a critical role in science history for the establishment of atoms and molecules as the building blocks of materials. This talk will discuss their role as Soft Matters, and as models for atoms and molecules. Spherical nanoparticles have been used to study the dynamics of crystallization. Non-spherical particles have been used to study liquid crystals. Despite their natural abundance and wide industrial applications,such as red blood cells and clay, disks and plates are the least studied nanoparticles compared to spheres and rods. We have established methods to fabricate and control the size, aspect ratio, and polydispersity of disks and systematically investigate their effects on discotic liquid crystal phase transitions.
