  • Development of a Novel Device to Measure the Viscosity of High Temperature Molten Salts

    Creator:
    Blyther, Joshua D.
    Abstract:
    This thesis presents a novel design for a rheometer style viscometer by implementing high temperature and inert atmospheric requirements on the device. The goals of this device are to measure the viscosity of high temperature molten salts, which are corrosive and extremely hydroscopic. It also aims to be able to...

  • Effect of ambient environment on the fracture and fatigue properties of Zr-based bulk metallic glasses

    Creator:
    Philo, Sarah L.
    Abstract:
    The effect of ambient environment on the fatigue behavior of two Zr-Ti-Cu-Ni-Be bulk metallic glasses (BMGs) is examined in the present study. The first metallic glass, Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅, was tested to establish the presence of an environmental effect in the fatigue growth curve measured in ambient air. Fatigue growth curves produced...

  • Dissipation and wavepacket collision in carbon nanotube waveguides

    Creator:
    Saranam, Venkata Rajesh
    Abstract:
    Carbon nanotubes (CNTs) superior mechanical, electrical and thermal properties make them attractive components in nanomechanical devices. Their large aspect ratio and low density makes them ideal candidates for high frequency resonators in numerous applications including wireless communication, and mass and chemical sensors. One reason why CNTs have been slow to...

  • Analysis and modeling of monolithic on-chip transformers on silicon substrates

    Creator:
    Mayevskiy, Yevgeniy
    Abstract:
    Passive components, including spiral inductors and transformers, fabricated on silicon-based substrates are placing an increasing demand on radio-frequency integrated circuit (RFIC) design. Performance of the RFIC suffers from several non-ideal effects that must be taken into account in order to create a successful design. In particular, monolithic transformers can be...

  • Comparison of time-domain and frequency-domain phase noise analyses

    Creator:
    Vytyaz, Igor
    Abstract:
    This thesis presents a comparison of time-domain and frequency-domain algorithms for phase noise calculation in oscillators. Floquet theory provides the mathematical foundation for these calculations and the numerical methods employ perturbation projection vectors (PPVs). The PPVs are an estimate of an oscillator's sensitivity to noise. The in-house circuit simulator SPICE3...

  • Developing Design Model for Cellulose Nanocomposites

    Creator:
    Shir Mohammadi, Meisam
    Abstract:
    Today nano scale materials are being used for wide range of applications. One promising topic in nano scale materials is using them for reinforcement of different polymeric materials to reach desirable stiffness properties. The stiffness of these materials is mostly found experimentally because the nanocomposite community lacks a decent analytical...

  • Rapid bidirectional power flow of supercapacitor bank energy storage through grid-tied inverters for improved renewables integration

    Creator:
    Bostrom, Arne
    Abstract:
    The variable output of renewables such as wind and solar causes fluctuations of power flow that can adversely affect power system operation, especially at high levels of penetration. The coordination of multiple energy storage solutions can mitigate integration challenges by providing a buffer from variable renewables. This thesis presents the...

  • Bioactive glass filled resin composites : mechanical properties and resistance to secondary tooth decay

    Creator:
    Khvostenko, Dmytro
    Abstract:
    Dental resin composites are widely used in modern dentistry due to their aesthetic appearance. However, resin based restorations have inferior mechanical properties (fracture is the second reason for restorations replacement) in comparison to alloy based composites and their antimicrobial properties still remain poor, leading to secondary tooth decay development on...

  • Characterization of load transfer in wood-based composites

    Creator:
    Schwarzkopf, Matthew John
    Abstract:
    The mechanical performance of composite materials is determined by the mechanical properties of their individual components and the effective load transfer between these components. Binders are commonly used to bond composite components together and to provide effective load transfer between them. In wood-based composites the binder-component load transfer occurs at...

  • Corrosion and fatigue of oil well drilling steels

    Creator:
    Rozman, Kyle A.
    Abstract:
    Oil drilling requires that miles of steel drill pipe, called the drill string, be exposed to fatigue loading and corrosive environments. Furthermore, it has been reported that pitting corrosion is responsible for initiating catastrophic drillstring failure. Pitting corrosion is responsible for initiating fatigue cracks, with pits acting as local stress...
