The physical and chemical properties of nanoparticles are often very different from those of the bulk materials, displaying some unique properties that depend on their size, shape, and surface functional groups. The unique and tunable properties of nanoparticles make them suitable for applications such as quantum dot displays, transistors, organic thin films, chemical and pressure sensors, adhesion and friction modifiers, and protective layers. Most of these applications require well-ordered large scale structures or films from smaller nanoparticles constructed using the socalled bottom-up approach. The research seminar will describe how the inter-nanoparticle interactions govern the assembly of hybrid-nanoparticles into nanostructures, and how the inter-nanoparticle interactions depend upon the nanoparticle shape, size, and concentration. Understanding and controlling the effects of nanoparticle shape, size, and concentration on particle-particle and particle-surface interactions are important for the processing of nanoparticles into ordered superstructured materials.
