Writers: L. F. Goncalves; L. S. R. Rocha; C. C. Silva; J. A. Cortés; M. A. Ramirez; A. Z. Simões Keywords: films; Dielectric properties Abstract: Bi3NbO7 (BNO) thin films were deposited on Pt/TiO2/SiO2/Si (100) and LaNiO3 bottom electrode substrates at room temperature from the polymeric precursor method. X-ray powder diffraction was used to […]
Writers: Paulo A. Raymundo-Pereira; Ana C. V. Mascarenhas; Marcos F. S. Teixeira Keywords: Biosensor; Electrochemical Abstract: The mediation of electron-transfer by oxo-bridged dinuclear ruthenium ammine [(bpy)2(NH3)RuIII(µ-O)RuIII(NH3)(bpy)2]4+ for the oxidation of glucose was investigated by cyclic voltammetry. These ruthenium (III) […]
