About this collection

This web theme aims to collect state of the art work on the surface chemistry of nanocrystalline materials with an emphasis on chemical reactivity, structural characterization, and physical or chemical structure/property relationship. We seek articles that explore nanocrystal structure, the binding of ligands, the influence of ligands on nanocrystal growth, the passivation of defect states by surface ligands, changes in electronic structure by surface ligands, the influence of nanocrystal surface structure on catalytic activity, and interfacial charge transport phenomena.
