\section{Introduction}  \subsection{Scope}  Nanostructure is an assembly of atoms or molecules with a microstructure at the nanoscale. Well-defined shapes of metal nanostructures such as cube \cite{Im_2005}, octahedron \cite{Xia_2012}, icosahedron \cite{Xiong_2007}, triangular plate \cite{Lofton_2005} and five-fold twinned pentagonal wire \cite{Tsuji_2008} can be synthesized in the colloidal system. A comprehensive review of shape-controlled solution-phase synthesis of metal nanostructures is given in the reference \cite{Xia_2008}. Although there numerous efforts to solidify the nucleation and growth mechanisms of these syntheses \cite{Lofton_2005,Mariscal_2012,Park_2013,Viswanath_2009,Liao_2014,Chang_2011,Murph_2015}, these mechanisms are yet elusive due to the lack of atomic resolution and quantitative data. This proposal describes how atomistic-scale simulation can be used to probe the nucleation and growth mechanisms.
