Approaches for the Quantitative Analysis of Oxidation State in Cerium Oxide Nanomaterials

September 21, 2018

Author(s)

Christopher M. Sims, Russell A. Maier, Aaron C. Johnston-Peck, Justin M. Gorham, Vincent A. Hackley, Bryant C. Nelson

Cerium oxide nanomaterials (nanoceria, CNMs) are receiving increased attention from the research community due to their unique chemical properties, most prominent of which is their ability to alternate between the Ce3+ and Ce4+ oxidation states. While many

Christopher Sims, Russell Maier, Aaron Johnston-Peck, Justin Gorham, Vincent A. Hackley, Bryant C. Nelson

Cerium oxide nanoparticles (nanoceria) are receiving increased attention from the research community due to the large number and wide range of their current and potential applications. The attractiveness of nanoceria for these various applications is

(Magic Dopant) Amphoteric Behavior of a Redox-Active Transition Metal Ion in a Perovskite Lattice: New Insights on the Lattice Site Occupation of Manganese in SrTiO3

October 5, 2016

Author(s)

Russell A. Maier, Matthew P. Donohue

It is definitively shown for the first time that a transition metal, redox-active ion can exhibit amphoteric substitution in the SrTiO3 perovskite lattice. The manganese dopant is preferably accommodated as Mn2+ on the strontium site and as Mn4+ on the

Low Temperature Ionic Conductivity of an Acceptor Doped Perovskite Part I: Impedance Spectroscopy of Single Crystalline SrTiO3

June 18, 2016

Author(s)

Russell A. Maier

Low temperature conductivity mechanisms are identified in acceptor doped SrTiO3 single crystals quenched from high temperatures under reducing conditions. Impedance spectroscopy measurements on samples of the prototypical perovskite structure doped with

Low Temperature Ionic Conductivity of an Acceptor Doped Perovskite Part II: Impedance Spectroscopy of Single Crystalline BaTiO3

June 16, 2016

Author(s)

Russell A. Maier

Low temperature conductivity mechanisms are identified in acceptor doped BaTiO3 single crystals equilibrated and quenched from high temperature under different oxygen partial pressures. A range of acceptor ionization states are quenched into samples doped
