Nanocrystalline BaFeO 4 was prepared and purified by special measures. Magnetic susceptibility measurements confirmed the existence of Fe(VI). X-ray diffraction studies indicated that they have an orthorhombic unit cell with space group Pnma and lattice parameters a=0.8880nm, b=0.5512nm, c=0.7214nm. High-resolution transmission electron microscopy (HRTEM) and selected area diffraction (SAED)...
Nickel nanorods with a diameter of 8-10nm and a length of 100-200nm have been prepared by reduction of nickel chloride with hydrazine hydrate in water/butanol/potassium oleate/kerosene microemulsion. Transmission electron microscope (TEM) and X-ray diffraction characterizations indicated that these nickel nanocrystallites were rod-shaped with a face-center-cubic phase. The possible growth process...
