  • The Impact of Crystal Morphology on the Opto-Electronic Properties of Amorphous and Organic Crystalline Materials

    Creator:
    Brandt, Gregory Mirek
    Abstract:
    Organic aggregates and transparent amorphous metals are transforming opto-electronic devices such as highly efficiency solar cells and flexible displays. We present a fundamental optical study of how local morphology critically impacts the device performance of both stacked, conjugated organics and In-Ga-Zn-O (IGZO) transparent metallic materials. Derivatives of anthradithiophene (ADT): ADTTES-F,...

  • Polarization Dependent Spectral Analysis Reveals Dipole Alignment and Intermolecular Coupling in Anthradithiophene Organic Semiconducting Crystals

    Creator:
    Lam, Andrew
    Abstract:
    Organic photovoltaics are being explored as the next generation material for semiconducting and optoelectronic devices but are limited by their stability and efficiency. One new candidate is crystallized Anthradithiophene (ADT), which is a promising photo-voltaic material due to its high quantum yield and adjustable side groups. The side derivatives TES-F,...

  • Red Raspberry Production Cost Comparison in Oregon and Chile

    Creator:
    McGuire, Madilynne J.
    Abstract:
    Red raspberry markets in both Chile and Oregon are affected by factors in each other‟s production processes. As seen in the late 1990‟s changes in pricing and supply can hinder the competitive edge of markets, pushing producers into economic hardship. Thus, the need to know the competition‟s methods is presented....

  • Photoluminescence Detection of 2,4,6-Trinitrotoulene (TNT) Binding on Single Cell Diatom Biosilica

    Creator:
    Harms, Nathan D.
    Abstract:
    T. pseudonana biosilica and live cells was explored as a biosensor for detection of the explosive compound 2,4,6-trinitrotoluene (TNT) in aqueous solution. The diatom frustule is an intricately nanostructured, highly porous biogenic silica material derived from the shells of microscopic algae called diatoms. This material emits strong visible blue photoluminescence...

  • Design and Implementation of a Modular Ocean Drifter Kit

    Creator:
    Green, Austin
    Abstract:
    Ocean Drifters are a low-cost and easy-to-use platform that are commonly used for studying ocean currents. With added interest in studying the ocean, emphasis has been taken to make it more accessible. A pilot course focused on introducing the topic of ocean sensing was announced. The HC 407 course will...

  • Prototyping of Thermoelectric Energy Harvesting Circuitry for IoT Devices

    Creator:
    Webb, Derek
    Abstract:
    Due to the advancement of incredibly low power microcontrollers and small form factor integrated circuits, energy harvesting can be considered as an alternative, low power source for remote ocean sensing and measurements. To demonstrate the effectiveness of harvesting thermoelectric energy contained in the temperature differential between ocean surface water and...

  • Crystal Morphology and Dimensionality Determine the Electronic Response in Novel Semiconducting Materials

    Creator:
    Grimm, Sam
    Abstract:
    Crystal morphology and dimensionality of single-crystal semiconducting materials can have dramatic effects on the optical and electrical properties. Organic photovoltaic (OPV) materials and fluorinated graphene folds are two materials that show these dependencies. Anthradithiophene (ADT), is an OPV that can be functionalized with different side groups to form different crystal...

  • Characterization of Mitochondrial Metabolism in L6 Rat Myoblasts

    Creator:
    Burney, Emily R.
    Abstract:
    The prevalence of obesity is increasing worldwide, causing a subsequent increase in insulin resistance (IR), metabolic disorders, and cardiovascular diseases. Although these conditions significantly impact both the individual and society, their etiologies have not been discovered, inhibiting potential prevention and treatment. Alterations to mitochondrial metabolism are implicated in the development...

  • Evaluating TEG Energy Harvesting Capabilities Across Naturally Occurring Temperature Gradients

    Creator:
    Estenson, Alyssa H.
    Abstract:
    Thermoelectric generators (TEGs) have gained much popularity in the search for alternatives to clean sources to harvest energy. Given their capability to harness an electric potential given a temperature differential across their opposing faces, and the foreseeable prevalence of naturally and/or commonly occurring temperature gradients in multiple applications, TEGs are...

  • Survival by Suicide: Motivation of Suicide Operations in the Middle East

    Creator:
    Schoen, Christopher M.
    Abstract:
    Suicide attacks are a prevalent topic in modern international media. The devastation in the United States caused by suicide tactics on September 11, 2001 encouraged the development of counter-terrorism policies that could provide effective security and reduce the worldwide sense of vulnerability. The necessity for international collaboration on research regarding...
