    Surface structures in doped perovskite ceramics

    The investigation of nanostructured transition-metal-perovskite materiais (TMPs) is attracting rapidly growing international attention owing to their unique dielectric properties and catalytic activity and consequent value in a variety of valuable applications including sensors, actuators, hydrogen production and environmental remediation. These materiais are of the general form AB03 wh...

  • Synthesis of SrTi1-xFexO3, Zn1-xCoxO and CuAlO2 thin film oxide compostions for application as gas sensors, AP.R

    Synthesis of SrTi1-xFexO3, Zn1-xCoxO and CuAlO2...

    Resistive gas sensors based on metal oxides in the form of thin or thick films are the devices most used and studied for the control of toxic and flammable gases in technological processes and open environment. Although a significant amount of work is being devoted to this field of research, efforts are being made in order to find materials that exhibit best surface and bulk properties ...
