Summary, Etc.  

요약In this work, we look closely the feedback between a nanoscale object and its environment and how it determines how the object behaves. In Part 2, I will focus on ions in confined spaces, particularly accounting for cases when the confining interfaces are polarizable due to dielectric mismatch. In this case, the induced polarization charge changes how ions move and distribute themselves in very narrow slits and near undulating interfaces. In Part 3, I will shift focus to nanoparticle self-assembly. In this case, we examine the competition between energy and entropy in determining the symmetry of an assembled nanoparticle crystal. I will present projects that examined the conditions under which binary systems of functionalized nanoparticles self-assemble into various crystal types, some of which allow the smaller of the two nanoparticle types to delocalize, even while the large particle lattice stays intact. In both Parts, we learn that in situations where ions are close to a wall or nanoparticles are very close to each other, the balance between different components of each interaction can play a large role in determining overall structure.
