DESCRIPTION:Speakers: Hongyi Xu (Department of Materials and Environmental
  Chemistry\, SU)\n\nX-ray crystallography is a powerful method for solving
  inorganic\, micro-molecular and macromolecular structures from 3D crystal
 s. However\, a historical challenge is to obtain crystals of suitable size
  and suitable solidity (in the protein case) to allow X-ray data collectio
 n. More specifically\, the growth optimization of protein crystals from mi
 crocrystals is often intricate/troublesome and not always successful. In t
 he past decades\, Zou and Hovmöller’s group has developed electron crys
 tallographic methods for structure determination of inorganic micron- and 
 nano-sized crystals. In 2010\, the Rotation Electron Diffractions (RED) te
 chnique was developed\, which combines mechanical goniometer tilt with fin
 e electron beam tilt (0.01 - 0.20°) to sample 3D reciprocal lattice of mi
 cron- and nano-sized single crystals. Zou’s group has applied the RED da
 ta for ab initio solution of more than 80 complex inorganic structures. In
  2015\, we implemented the continuous RED (cRED) technique based on RED an
 d literatures by Nannenga et al.(2014) and Gemmi et al.(2015)\, which exte
 nded our ability to determine structures of small organic molecules and pr
 oteins from micron- and nano-sized 3D crystals. \n\nHongyi Xu(1)\, Hugo Le
