MicroED Structure of Hexagonal Ice Ih Michael W. Martynowycz Tamir Gonen 10.26434/chemrxiv.8298641.v1 https://chemrxiv.org/articles/MicroED_Structure_of_Hexagonal_Ice_Ih/8298641 The structure of ice Ih is solved from a single nanocrystal to a resolution of 0.53Å using the cryoEM method microcrystal electron diffraction (MicroED). Data were collected at just above liquid nitrogen temperatures (~80K) in ultra-high vacuum (~8 x 10-7 Pa) using a total exposure of less than 1e- Å-2. <br> 2019-06-20 15:08:46 MicroED cryoEM nanocrystals ice
