We describe here the use of high-temperature oxidation and reduction to produce highly crystalline nano-
particles of Ni and NiO. Starting with an amorphous Ni powder, we demonstrate that oxidation at 900 C
produces faceted NiO nanocrystals with sizes ranging from 20 to 60 nm. High-resolution transmission electron
