Electrochemomechanics in Mixed Ionic Electronic Conductors and solid oxide cells
… a model for coupled electrochemomechanics in Mixed Ionic Electronic Conductors (MIEC). A continuum model is formulated to simulate the transport of ionic defects and the stress distribution in the conductor arising from the chemical expansion associated with the defects. First, a finite …

Light and Charge Management in Optoelectronic Systems
… of photogenerated charge in the context of mixed ionic electronic conductors. We introduce a new interpretation of surface photovoltage measurements for these materials and demonstrate control over transport of charge throughout the material. Thereafter, we explore the physical implications …

Understanding and Controlling the Surface Chemistry of Oxides to Enhance Catalytic Activity at Elevated Temperatures
… way to perform the OCM reaction using mixed ionic-electronic conductors (MIEC) as a backbone electrode and OCM-active secondary particles deposited onto the surface of the MIEC electrode. Optimizing the dispersion of the OCM-active secondary particles has been proposed as a promising …

$^{17}$O Solid-State NMR Spectroscopy of Functional Oxides for Energy Conversion
… a class of perovskite-derived structures used as mixed ionic-electronic conductors (MIECs) for SOFC cathodes, and (2) further uses of multinuclear variable-temperature NMR spectroscopy, with emphasis on $^{17}$O NMR results, to elucidate mechanistic details of oxide-ion motion and sublattice …

Characterization and control of non-stoichiometry in Pr₀.₁Ce₀.₉O₂-[d̳e̳l̳t̳a̳] thin films : correlation with SOFC electrode performance
… solution system as a model system given its mixed ionicelectronic conductivity, well described defect equilibria and transport properties, and stability over with limits of temperature and oxygen partial pressure. PrCel-02-6 (PCO) thin films with x=0.01, 0.10 and 0.20 were prepared as thin …

Monitoring Tissue Function Dynamics in vitro with Bioelectronics: Towards Understanding Barrett’s Oesophagus Pathogenesis
… function is to measure the flux of solvated, ionic species across the epithelium, in response to an applied electrical potential difference. Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), a conjugated polymer blended with a poly-electrolyte, is identified as a suitable …
