  • Environmental Transformations in Hydrophobicity of TiO2 P-25 Nanoparticles in Alsea River Waters

    Creator:
    Boenisch, Kylie
    Abstract:
    Hydrophobic titanium dioxide (TiO2) nanoparticles (NPs) are prevalent in industry and manufacturing. They are known for their white pigmentation, are found in sunscreens, paints, cosmetics, and are frequently used in wastewater treatment. Understanding the physicochemical properties of TiO2 P-25 NPs, such as hydrophobicity, are essential when determining their fate, transport,...

  • Examination of Dielectric Properties of BaTiO3-SrTiO3 Based Systems

    Creator:
    Trobough, Nathaniel D.
    Abstract:
    This thesis examines the dielectric properties of two systems based on the perovskite materials barium titanate and strontium titanate. A solid solution was created starting with these base materials and then adding varying amounts of bismuth-zinc titanate and sodium niobate. These compositions were calcined and sintered at temperatures determined to...

  • A Study of Learning Effectiveness between Augmented and Traditional Methods in Crafting Origami

    Creator:
    Ramos, Symon P.
    Abstract:
    Traditionally, people learn to perform object assembly tasks by following the steps in a paper-based instruction manual. Using augmented reality (AR) technology, the instructions could instead be computer generated and appear directly within the user’s workspace as they perform the task. Literature suggests AR’s feasibility in improving performance and learning...

  • CO₂ capture from wet flue gas using a water-stable and cost-effective metal-organic framework

    Creator:
    Loughran, Ryan P.
    Abstract:
    We report the use of MIL-120 as a water-stable and cost-effective metal-organic framework (MOF) for selectively capturing CO₂ from wet flue gas. Synthesized using inexpensive and environmentally benign reagents in water, MIL-120 possesses one-dimensional pores decorated with hydroxyl-bridged Al(III) ions and benzene rings with an interstitial spacing of 4.78 Å....

  • Investigation of MoS2 with Ambient Pressure X-ray Photoelectron Spectroscopy

    Creator:
    Dardzinski, Derek P.
    Abstract:
    Molybdenum disulfide (MoS2) has potential applications as a low-cost catalyst for the hydrogen evolution reaction (HER). Defects on MoS2, such as edge sites and sulfur vacancies, are known to be the major active sites for HER. Controlling the formation of these defects allows for the enhancement in reactivity of MoS2...

  • Atmospheric nitrous oxide in the pre-800 ka atmosphere from ice cores from the Allan Hills, Antarctica

    Creator:
    Stock, Marika P.
    Abstract:
    Nitrous oxide is an important greenhouse gas that has both natural and anthropogenic sources in the modern atmosphere (Ciais et al., 2013). This project expanded the knowledge of the history of atmospheric N2O in the geologic past by measuring N2O concentrations in air trapped in very old polar ice. A...

  • Cutting performance comparison of low-kickback saw chain

    Creator:
    Otto, Andrew and Parmigiani, John P.
    Abstract:
    Kickback is the leading cause of the most severe and traumatic chainsaw-related injuries. As a result, safety standards require chainsaw manufacturers to produce low-kickback saw chain. In order to understand the tradeoffs in current state-of-the-art saw chain, a comparison study was conducted on a custom test apparatus using four different...

  • A Systematic Review of Diversity and Inclusion Scholarly Sources in Natural Resources (1919 – 2018)

    Creator:
    Brown, Jasmine K. and Rempel, Hannah G.
    Abstract:
    This dataset was created for the purpose of collecting and cataloguing sources that mentioned aspects of cultural diversity or workforce diversity within natural resource professions. The exploratory questions that prompted the collection of sources in this dataset were: - Is diversity discussed in scholarly sources within natural resources? - If...

  • Hacking RFID Tags to Produce Economical Soil Moisture Sensors

    Creator:
    Stoddard, Brett S.
    Abstract:
    Currently available soil moisture sensors have intrinsic limitations that limit their adoption by industry. Depending on the technology, these limitations may include high costs, battery requirements, precice manual installation, high cost, and/or constrictive legislation that regulates their use. A passive soil moisture sensing system based around RFID technology would allay...

  • Adaptive Learning Module for Introduction to Materials Science

    Creator:
    Nigon, Nutnicha
    Abstract:
    There is a growing need for individualized instructional designs in 4-year institutions due to: 1) growing undergraduate enrollment trends across the U.S., 2) broader diversity in students backgrounds, and 3) the growing prevalence of asynchronous remote learning. With the growth in computer technology in education, tools such as adaptive intelligent...
