... crystals of the metal halide THF adduct, except for the vanadium, whose crystals were instead ferrocene. This suggests that somewhere along the way, either the ligand was displaced from the metal, or that THF binds to the metal better than dafc. Additionally, because ferrocene was found in the vana ...

This effect is associated with reduced activation energy of the grain boundary diffusion [14] and a large volume fraction of grain boundaries in the UFG samples. In this case, the smaller particle size (5 nm) in the ECAP samples compared to the size of the ...
