  • Direct Numerical Simulation of Anisotropic Particles in Turbulent Flow

    Creator:
    Roberts, Kai
    Abstract:
    Turbulent flows with suspended, non-spherical particles are common in many natural and industrial processes. To identify the effects of anisotropic geometry on particle dynamics, a one-way coupled Lagrangian direct numerical simulation solver was written, verified, and used to collect data on particles simulated in multiple flows. This thesis explains the...

  • 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...

  • Hydrogen Interaction with Platinum and Palladium Surfaces

    Creator:
    Boechler, Amanda N.
    Abstract:
    Platinum and palladium surfaces are utilized as catalytic surfaces in the chemical industry. Understanding how hydrogen atoms interact with the metal surfaces will allow for further advancement in this area. Specifically, the interaction of hydrogen on the surface and subsurface of these metals was investigated using density functional theory calculations...

  • Fungal endophytes as source to combat bacterial infections

    Creator:
    Green, Jaimie R
    Abstract:
    Endophytes, foliage inhabiting fungi, are an unexplored source of fungal biodiversity and a potential resource for the production of bioactive natural products. In this research, leaf tissues from the species Arbutus menziesii, Rhododendron macrophyllum and the genus, Ilex and Salix were collected for the isolation of endophytic fungi. Fungal extracts...

  • Examining Wildlife Interactions with Large Wood In Streams

    Creator:
    Trevarrow, Ezmie R.
    Abstract:
    It is well known that in-stream large wood affects river channel shape, sediment deposits, stream flow, and available habitat for aquatic species. However, less is known about how wildlife interact with this large wood. Previous research has shown that small mammals and birds utilize woody debris in river channels for...

  • Simulating the Dynein Motor Protein: A Monte Carlo Approach to Achieve Coordinated Stepping

    Creator:
    Kiatvongcharoen, Jin
    Abstract:
    The motor protein dynein is responsible for cellular processes such as axonal transport and cell division by delivering vital information along the microtubule track. A failed delivery can cause severe damage to the cell’s functionality and lead to neurological diseases. Despite dynein’s rich history in cellular research, the mechanism of...

  • Drunken Walking: A Novel Brownian Dynamics Simulation for the Mechanochemical Cycle of the Dynein Motor Protein

    Creator:
    Waczak, John L.
    Abstract:
    The dynein molecule is a peculiar motor protein recognized for its unique stepping behavior. Sometimes it steps forwards. Other times it steps backwards. It has even been observed to occasionally shuffle by beginning a step with the same domain many times in row. These motions make dynein an interesting object...

  • Real-time Speech Workload Estimation

    Creator:
    Fortune, Julian D.
    Abstract:
    Demanding task environments (e.g., supervising a remotely piloted aircraft) require performing tasks quickly and accurately; however, periods of low and high operator workload can decrease task performance. Intelligent modulation of the system’s demands and interaction modality in response to changes in operator workload state may increase performance by avoiding undesirable...
