3D Structure of Inorganic Nanocrystals in Solution by Transmission Electron Microscopy


Scientific Achievement

Measured the locations of all of the atoms in colloidal nanocrystals for the first time, with resolution of 2.15 Å.

Significance and Impact

Nanocrystals are a fundamental building block of nanoscience, yet until now we have only known the average positions of atom within them. This will enable scientists to control nanocrystals which are used in solar cells, batteries, displays, catalysts, and more.
