\subsection{Mechanistic Studies of Shape Control}  %  Background: Xia 2015 Kinetics Thermodynamics. Xia 2013 Surface diffusion. Nanocrystals synthesis can be viewed as a set of sequential and parallel chemical reactions.  Each route of chemical reactions yields nanocrystals of different dimensions and morphology. 

Consequently, $V_{diffusion}$ is mainly determined by the reaction temperature and the height of the potential energy barrier.  The height of the potential energy barrier can be affected by factors such as the strength of bond between the surface atom and the adatom, the crystallographic plane of the surface, and capping agents surface passivation.  %  Experiments: %  Cubes %  Wires %  PVP facet selectivity %  PVP interactions %  Bridge Tang 2008 Strain-induced %  Simulations: %  Fichthorn DFT %  Fichthorn Force field %  Solvent effects in experiments %  Fichthorn solvent
