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)...
The deposition of nitrogen-containing carbon films on silicon substrates at atmospheric pressure and low temperature has been carried out by electrolysis of methanol and ammonia solutions. Amorphous carbon films containing about 8% nitrogen were obtained. The observed C–N vibration bonds by Raman and FTIR spectroscopy and the chemical states by XPS of C and N atoms indicate that the carbon and nitrogen...
