  • Evaluation of Stress Corrosion Cracking of 316L Stainless Steel in FLiNaK Using the Slow Strain Rate Technique

    Creator:
    Quintana, Xavier A.
    Abstract:
    Molten salts have been targeted as a promising coolant for next generation reactors due to their high boiling point, heat capacity, and thermal conductivity. Despite these benefits, molten salt systems present unique materials compatibility issues, highlighted by the aggressive corrosion attack and dealloying typically seen on materials in these environments....

  • Fabrication and geometrical characterization of metal and metal-dielectric composite periodic nanostructures

    Creator:
    Bhowmik, Siddhartha
    Abstract:
    Periodic metal and metal-dielectric composite nanostructures have been of interest from the field of plasmonics and metamaterial fabrication. In order to exploit the behavior of these unique materials in the visible region of the optical spectrum, these structures need to be significantly shorter than the wavelength of response, and hence...

  • Functional Materials and Techniques for Additive Manufacturing in Soft Robotics

    Creator:
    Walker, Stephanie
    Abstract:
    This thesis outlines the development of new elastomeric materials and manufacturing processes for soft robotics. Specifically, this work describes the development of custom material formulations for use in additive manufacturing, additive manufacturing processing techniques for silicone elastomers, and multi-component additive manufacturing techniques. Material synthesis and processing is a gap in...

  • Influence of processing parameters on diffusion of divalent nickel in wet silica sol-gel monoliths

    Creator:
    Dickson, David J.
    Abstract:
    The diffusion of divalent nickel (Ni²⁺) from wet silica gels was investigated. Silica gel is gaining interest as an encapsulation matrix for biological components. The transport of biologically relevant species within the gel is determined by the structural characteristics of the gel, which are in turn governed by synthesis parameters....

  • Development of Cu-based Thin Films for Optoelectronic Applications

    Creator:
    Angelos, Gregory S.
    Abstract:
    CIGS and CdTe based commercial thin-film solar cells (TFSCs) require an absorber thickness greater than 2 µm and 4 µm, respectively, to adequately absorb the solar spectrum. To efficiently extract photoexcited electrons, these TFSCs require relatively defect-free absorbers with high-minority carrier mobility (> 100 cm2V−1s−1) and long lifetime (> 10...
