  • Degradation of N-Nitrosodimethylamine Using Photo-Catalysis and Microreactor Technology : Experimentation and Modeling

    Creator:
    Omar, Mohamed
    Abstract:
    The cleanliness of water is a major issue with regards to humanity's continued survival. The chlorination and chloro-amination of water is essential to the creation of microbiologically clean water. However these processes also give rise to oxidative byproducts such as nitrosamines. In particular, due to its high toxicity, N-Nitrosodimethylamine (NDMA)...

  • Development of Temperature-Stable Relaxor Dielectrics for High Energy Density Capacitor Applications

    Creator:
    McCue, Connor
    Abstract:
    High performance dielectric materials are needed for high power SiC- or GaN-based electronics which combine the best features of high energy density, low dielectric loss and high reliability and for advanced high-speed and high-voltage energy storage where temperature stability plays an important role in material properties. An ideal capacitor for...

  • Material development for thin-film transistors

    Creator:
    Archila, Kevin Alexander
    Abstract:
    The focus of this thesis is developing materials for thin-film transistors (TFTs). Cu₃SbS₄ is explored as p-channel layer. Cu₃SbS₄ TFTs show p-type, depletion-mode behavior with a small amount of gate-controlled modulation of the channel conductance. This behavior is consistent with Hall measurements indicating a mobility of 17 cm²V⁻¹s⁻¹ and hole...

  • Dynamic biasing for ring amplification

    Creator:
    Farahbakhshian, Farshad
    Abstract:
    New amplifier architectures are presented using non-traditional methods of biasing. Time-based dynamic biasing and signal-based dynamic biasing are discussed in the context of new architectures. This includes a new form of ring amplification with a dynamic deadzone, allowing for a structure whose coarse path does not consume static power.

  • A shared-autonomy heavy-lift assistive robot for manufacturing

    Creator:
    Finley, Taylor M.
    Abstract:
    Automating pick-and-place operations for large steel castings in a foundry is challenging, particularly from a perception point of view. Accurately estimating the identity and orientation of a given part is an open and complex problem, especially if that part sits in a bin of very similar parts. The problem is...

  • Designing Dielectric Materials through Complex Metal Oxides

    Creator:
    Nikkel, Jason W.
    Abstract:
    This dissertation demonstrated that the electrical properties of complex oxide-based perovskite materials could be controlled through the careful modification of both material composition and structure. This was first shown through the modification of lead zirconate titanate (Pb(Zr0.52Ti0.48)O3, PZT) solid solutions with bismuth indate (BiInO3, BI) where the relative stability of...

  • Power-Efficient Design Techniques and Architectures for Scalable Submicron Analog Circuits

    Creator:
    Xu, Yang
    Abstract:
    As the CMOS process scales down to submicron, digital circuit performance improves, while reduced supply voltage and lower transistor intrinsic gain make it difficult to implement analog circuits in a power efficient manner. Therefore, it has become advantageous to shift more analog signal processing functions conventionally realized in voltage (analog)...

  • Exploring the Distinct Solution Behavior of Isostructural Polycoltanates

    Creator:
    Fullmer, Lauren
    Abstract:
    Polyoxometalates are a rapidly growing class of discrete metal oxide clusters with a wide range of applications including functional materials. These anionic clusters of the group V and VI transition metals are inexpensive and non-toxic. Within group V polyoxometalates, niobium and tantalum chemistry has been underdeveloped owing to their unique...

  • Probing Aqueous Ion-Pairing and Speciation of Group V Polyoxometalates

    Creator:
    Sures, Dylan J.
    Abstract:
    Polyoxometalates are discrete anionic oxo clusters of the Group V and VI transition metals that can be conceptualized as molecular metal oxides. Because they are pairable with any alkali cation, a great deal of fundamental chemistry can be gleaned from their study, including solubility trends and insight into cation binding...

  • Nutrient Addition Strategies for the Marine Diatom Cyclotella sp to Control Cell, Lipid, and Chitin Formation.

    Creator:
    Chiriboga Novillo, Omar Guillermo
    Abstract:
    Marine diatoms are unicellular photosynthetic organisms that produce unique nanomaterials, energy dense lipid-molecules, and specialty carbohydrate molecules that can be all extracted from a single microorganism. The centric marine diatom Cyclotella sp. was used as a model organism for cultivation in a biorefinery system, where multiple co-products can be harvested...
