- Abstract
This article discusses the analysis of the three-dimensional (3D) and four-dimensional (4D) structures of colloidal nanoparticles using graphene liquid cell transmission electron microscopy (TEM). Colloidal nanocrystals have various applications, but their unique structural characteristics at the nanoscale require new analysis methods. The "one-particle Brownian 3D reconstruction method" allows for the precise determination of the positions of constituent atoms in single nanocrystals directly from the solution phase. The method has been extended to determine the 3D atomic structures of multi-element nanoparticle systems. Additionally, tracking the structural changes of nanocrystals with 3D atomic resolution can help understand the underlying mechanisms of chemical reactions. The study suggests that it is possible to investigate the 3D atomic structures of synthesized multi-element nanoparticles in a liquid phase.
