Description:Literature Seminar Abstract\n\nSelf-assembly has occurred in na
 ture since the beginning of time\, but only in the past 30 years has the t
 erm found its way into chemical literature to describe autonomous organiza
 tion in various systems\, from monolayers to nanoparticle superstructures.
  Nanoparticle self-assembly can be used as a high throughput method for th
 e fabrication of thin-films as well as the formation of 3D architectures. 
 While a wide variety of interactions are known to contribute to nanopartic
 le self-assembly\, surface chemistry is complex\, and a major challenge of
  the field is to elucidate the interactions driving self-assembly. A recen
 t report from Tan et al. uses in situ transmission electron microscopy (TE
 M) to investigate self-assembly of Au nanoparticles capped with hydrophobi
 c ligands in water. They determine that nanocube self-assembly is orientat
 ional and driven by hydrophobic interactions between the ligands and water
 \, and that nanoparticle morphology affects the strength of these interact
 ions. Molecular dynamics simulations provide further insight into the forc
 es governing interparticle interactions. Their work serves as a model for 
 the systematic study of the driving forces in self-assembly.\n\nTan\, S. F
