  • Analyzing the Kinetics and Thermodynamics of Surface Reactions using Density Functional Theory

    Creator:
    Sprowl, Lynza H.
    Abstract:
    The interactions of chemical species with a solid surface play a role in many everyday applications such as heterogeneous catalysis, corrosion, and degradation reactions. Understanding the reaction kinetics and thermodynamics via rate constants and equilibrium constants, which require knowledge of the adsorbed species’ entropy, is essential for tuning these surface...

  • Understanding of Ferroelectric to Relaxor Phenomenon in Bismuth-based Perovskite

    Creator:
    Gupta, Sanu K.
    Abstract:
    It has been well established that ferroelectric to relaxor crossover in piezoelectric ceramics exhibit promising electromechanical and dielectric properties over a wide temperature range, applying sensors and actuators transducers and such. A plethora of research has reported giant strain in various lead-free piezoelectric ceramics and attributed the reasoning to the...

  • The Local Structure of Functional Electroceramics

    Creator:
    Culbertson, Charles M.
    Abstract:
    This work investigates the relationship between the local structure and physical properties of a set of classical (MgTiO3, CaTiO3, SrTiO3, and BaTiO3) and complex ((1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3[BZT-BCT], Na0.5Bi0.5TiO3 [NBT]) perovskite electroceramics. The materials in this work were synthesized via standard solid state ceramic synthesis, the structure was investigated through a number of...
