Analysis of deposited magnesium. (a) Dark-field TEM reveals a very porous microstructure of deposited magnesium compounds. (b) Selected area electron diffraction reveals a ringlike pattern that fits well with the expected pattern for nanocrystalline cubic MgO (space group Fm3̅m). (c) Presence of a nanocrystalline material further supported by high-resolution TEM.
