Better Imaging of 3D Nanocrystals

Electron diffraction of 3D nanocrystalline molecular assemblies is an increasingly popular alternative to conventional crystallographic approaches. My group is focused on the investigation of tools and methods that facilitate the rapid and accurate determination of atomic molecular structures from 3D nanocrystals.

Our recent work involves the use of 4D STEM to map nanoscale changes in crystalline lattice features within nanocrystals, and analyses of the effects of radiation damage on nanoscale molecular assemblies interrogated by high-energy electrons.

Our collective knowledge of these problems informs on the trustworthiness of molecular structures obtained by electron diffraction and portends a growing utility for the method.
