Presentation Transcript

  1. Our team has discovered an unusual multi-species defect-transport coupling process occurring in these materials when employed in gas permeation applications. Simultaneous mixed conduction of protons (OHO•), oxygen vacancies (V••), and electronic defects (electrons or holes) enables the separation of oxygen, hydrogen or steam and, remarkably, can even force any one of these species to be transported against its concentration gradient (uphill diffusion). We believe that these materials can be used to great advantage in applications such as membrane reactors for chemical processing. Novel Transport Mechanisms in Conducting CeramicsCraig P.
