Evolution of zinc morphology during continuous electrodepositionAiling Fan, Wenhuai Tian, and M.KurosakiDepartment of Materials Physics and Chemistry, University of Science and Technology Beijing... evolution of zinc continuous electrodeposits with nano-sized crystals on the ferrite substrate has been studied by in-situ scanning tunnel spectroscopy (STM). It is found that the morphology of zinc......
produce three NiFe2O4, the diffusion of two Fe3+ ions results in only one NiFe2O4. The results of the evolution of microstructure show that the domain structure which makes up of the agglomerative..., polyhedral structure and high surface area is synthesized by high temperature solid state reaction. The evolution of microstructure from raw materials NiO and Fe2O3 to the reaction resultant NiFe2O4-10NiO......
