  • Fabrication and optical measurement of flip-chips for noninvasive electrostatic gating of nanomaterials

    Creator:
    Nichols, Dublin MacCray
    Abstract:
    Electrostatic gating of nanomaterials allows researchers to control carrier density and shape potential barriers that confine carriers. Lithographic patterning followed by metal deposition is the standard technique to define electrostatic gates; however, the methods of fabricating these devices often involve harsh processing. For example, taking a material to high temperatures...

  • Student Thoughts on Derivatives of Vector Fields

    Creator:
    Walker, Mesa E.
    Abstract:
    Junior level physics students are familiar with a few types of vector field derivatives, such as divergence and curl, but are typically unfamiliar with how to take a general derivative of a vector field. Three junior-level physics students were interviewed with the open-ended prompt, “How would you think about taking...

  • Isolation of New Niobium clusters with Alkali Carbonate

    Creator:
    Feng, Ching-Lei
    Abstract:
    Polyoxoniobates (PONbs) are attracting great attention in recent years due to its novelty as well as a variety of geometrical presentations in different pH conditions. In this paper we are reporting the reaction of tetramethyl-decaniobate ([(CH3)4N]6[Nb10O28]) with alkaline carbonates to observe the periodic trend of alkaline ions interacting with the...

  • Survey of isotope ratios in the near coastal outflow of the Columbia River

    Creator:
    Dolan-Caret, Amari
    Abstract:
    This report details ocean water salinity and stable isotope measurements (deuterium (D) and 18O) in water collected from April 17 2018 to April 21 2018 in the coastal waters of Oregon, USA. Measurements were made from surface, ship flow-through, and CTD rosette bottle samples collected as part of a student-led...

  • GradPlan : Create Your Program of Study with Ease

    Creator:
    Almeida, Jonathan Gregory
    Abstract:
    New MS in CS students in the Electrical Engineering and Computer Science school at OSU are required to file their Program of Study by the end of their 2nd term. Many of them, especially international students, are in a totally new ecosystem, so they find it overwhelming to choose the...

  • Mathematical and Computational Considerations of a Model of Microbiologically Induced Calcite Precipitation

    Creator:
    Barry, Zachary T.
    Abstract:
    In this paper, we discuss two possible modifications to a numerical solution method for a model of microbiologically induced calcite precipitation (MICP). MICP provides a means to seal cracks in the surfaces of geological structures. From a mathematical and computational point of view MICP has very interesting features which make...

  • Small Scale Modeling of a Broad Area Detector Network Array

    Creator:
    Johnson, Patrick M.
    Abstract:
    Nuclear material monitoring systems have long been established at ports of entry. However, there are no standard systems for monitoring points of interest within the country. Therefore, the use of a network of radiation sensors deployed throughout an area of interest is being investigated within this thesis. Before full scale...

    Creator:
    Polasky, Sophia
    Abstract:
    International development programs are often implemented with the goal of building community resilience, but without a clear articulation of how this goal will be met, or any consideration of if or why the effort was successful after it has concluded. This thesis considers three different activities implemented by the U....

  • Examining the Effects of Artisanal, Small-scale Gold Mining on Livelihood Assets in Kedougou, Senegal

    Creator:
    Zoch, Grant L.
    Abstract:
    The frontlines of climate change adaptation will occur in rural, impoverished regions of the world where households engage in climatically dependent livelihoods, such as peasant agriculture or pastoralism. As changing climate and changing markets affect the suite of household livelihood assets (environmental, social, and economic) which enable a household to...
