  • Novel nanocomposite synthesis for high-performance thermoelectrics

    Creator:
    Eilertsen, James S.
    Abstract:
    Thermoelectric materials are playing a larger role in the global effort to develop diverse, efficient, and sustainable energy technologies: primarily through power-generating thermoelectric modules. The principal components of thermoelectric modules are solid-state thermoelectric materials – typically heavily doped semiconductors – that convert heat directly into electricity. However, this conversion efficiency...

  • Fracture toughness of void-site-filled skutterudites

    Creator:
    Eilertsen, James S.
    Abstract:
    Thermoelectric materials are playing an increasingly significant role in the global effort to develop sustainable energy technologies. Consequently, the demand for materials with greater thermoelectric efficiency has stimulated the development of state-of-the-art interstitially doped skutterudite-based materials. However, since intermetallics are often embrittled by interstitial substitution, optimal skutterudite-based device design, manufacture,...

  • Fracture Toughness of Co4Sb12 and In0.1Co4Sb12 Thermoelectric Skutterudites Evaluated by Three Methods

    Creator:
    Eilertsen, James, Subramanian, M. A., and Kruzic, J. J.
    Abstract:
    Interstitially filled skutterudites are a promising class of state-of-the-art thermoelectric materials. Although thermoelectrics are exposed to significant thermal stresses, little information is known about the fracture toughness of interstitially doped skutterudites. This work explores the fracture toughness of undoped Co₄Sb₁₂ and indium doped In₀.₁Co₄Sb₁₂ skutterudites using three methods: 1) Vickers...

  • Rapid Microwave Synthesis of Indium Filled Skutterudites: An energy efficient route to high performance thermoelectric materials

    Creator:
    Biswas, Krishnendu, Muir, Sean, and Subramanian, Mas A.
    Abstract:
    Filled skutterudites are promising thermoelectric materials due to reduced thermal conductivity upon inserting a guest atom or 'rattler' into the CoSb₃ structure. By using an indium rattler dimensionless Figure of Merit (ZT) values > 1 at 650 K have been reported. The conventional synthesis of these compounds typically takes several...

  • Synthesis and investigation of layered oxides with honeycomb ordering

    Creator:
    Schmidt, Whitney L.
    Abstract:
    Synthesis and discovery lies at the core of every field in chemistry. The investigation of the structure-property relationships in compounds known or new is the fundamental purpose of solid state chemistry. Mixing related solid state compounds to form solid solutions can lead to exciting new and/or unexpected properties. Layered compounds...

  • Structure-property relationships in oxides containing select platinum group metals

    Creator:
    Gatimu, Alvin J.
    Abstract:
    Oxide materials exhibit a wide variety of structures and properties. In particular, transition metal oxides tend to be highly stable while exhibiting a wide range of properties that can be used for numerous applications. This work focuses on investigating how the structures’ of 4d and 5d transition metal oxides influences...

  • Investigation of the structural influence on the properties of functional inorganic oxides

    Creator:
    Laurita-Plankis, Geneva
    Abstract:
    While properties are extremely important from an application point of view, it is crucial to have a detailed understanding of the underlying structural influence. Once a concrete correlation between the structure and the observed property is established, rational design of novel materials with optimized properties can be realized. These optimized...

    Creator:
    Tang, Joseph N.
    Abstract:
    Structure-property relationships have always underpinned the field of solid state chemistry; dependable structural descriptions are integral to understanding and controlling the physical properties of inorganic compounds old and new. While a handful of crystal structures are celebrated for their versatility, flexibility, and functionality, the existence of more exotic structures is...

  • Structure-property relationships of YbFe₂O₄-type layered transition metal oxides

    Creator:
    Grajczyk, Rosa
    Abstract:
    The structure–property relationships of solid solutions within the YbFe₂O₄ family of compounds have been studied in relation to their optical, dielectric and magnetic properties. This family of compounds is of recent interest because of the trigonal bipyramid coordination that is rarely observed in transition metal oxides. The systematic study of...
