Electrical conductivity and defect chemistry of BaxSr1 - xCoyFe1 - yO3 - dBaxSr1?xCoyFe1?yO3? perovskites

Yáng, Z. (author), Harvey, A.S. (author), Infortuna, A. (author), Schoonman, J. (author), Gauckler, L.J. (author)

Bulk BaxSr1 - xCoyFe1 - yO3 - dBaxSr1?xCoyFe1?yO3? compositions (BSCF) were synthesized by the solid-state reaction method. The electrical conductivity of ceramic bars was measured using a dc four-probe method as a function of temperature in air up to 970 °C. All compositions showed thermally activated p-type semi-conductivity up to ~450 °C and...

Electrosprayed Metal Oxide Semiconductor Films for Sensitive and Selective Detection of Hydrogen Sulfide

Ghimbeu, C.M. (author), Lumbreras, M. (author), Schoonman, J. (author), Siadat, M. (author)

Semiconductor metal oxide films of copper-doped tin oxide (Cu-SnO2), tungsten oxide (WO3) and indium oxide (In2O3) were deposited on a platinum coated alumina substrate employing the electrostatic spray deposition technique (ESD). The morphology studied with scanning electron microscopy (SEM) and atomic force microscopy (AFM) shows porous...

Diffusion Impedance on Nickel/Gadolinia-Doped Ceria Anodes for Solid Oxide Fuel Cells

Aravind, P.V. (author), Ouweltjes, J.P. (author), Schoonman, J. (author)

Electrochemical impedance measurements were carried out on symmetrical nickel/gadolinia-doped ceria test cells. For H2, N2, and H2O mixtures, the diffusion length obtained based on the impedance measurements is on the order of centimeters. This high value of the diffusion length is attributed to the flow field in the reactor. It is suggested...

Electrochemical Oxidation and Determination of Oxalic Acid at an Exfoliated Graphite-Polystyrene Composite Electrode

Schoonman, J. (author), Manea, F. (author), Radovan, C. (author), Corb, I. (author), Pop, A. (author), Burtica, G. (author), Malchev, P.G. (author), Picken, S.J. (author)

An exfoliated graphite-polystyrene composite electrode was evaluated as analternative electrode in the oxidation and the determination of oxalic acid in 0.1 M Na2SO4supporting electrolyte. Using CV, LSV, CA procedures, linear dependences I vs. C wereobtained in the concentrations range of oxalic acid between 0.5 to 3 mM, with LOD =0.05mM, and...
