  • Surface composition age analysis of photo-oxidized polystyrene thin films by X-ray photoelectron spectroscopy

    Creator:
    Silva, Nicholas A.
    Abstract:
    Polystyrene thin film surfaces are commonly used to study the interactions of macromolecules, such as proteins, with surfaces. Polystyrene films oxidized in UV light become more hydrophilic, however these surfaces have a limited shelf life because they are reduced over time. Experiments were performed to determine the effect of radiation...

  • Solar Thermal Energy System for Renewable Desalination

    Creator:
    McLaughlin, Ryan P.
    Abstract:
    Natural freshwater availability is decreasing as the global population increases. Advances in desalination technologies aim to produce fresh water in an economical way. More sustainable energy sources are desired for these desalination plants to limit the carbon footprint of water production since global carbon dioxide production is exacerbating freshwater scarcity....

  • Ultraviolet photolysis of acetaminophen in a 3D printed continuous flow reactor

    Creator:
    Goetze, John M.
    Abstract:
    Finding renewable sources of agricultural fertilizer will be necessary to ensure a stable food supply for future generations. Phosphorus is of particular concern, since mining phosphate rock is the main source and reserves are forecasted to deplete in the next 50 – 200 years. Human urine contains substantial amounts of...

  • Systematically evaluating the developmental toxicity of nanomaterials using the zebrafish model

    Creator:
    Edwards, Sabrina R.
    Abstract:
    As engineered nanomaterials (ENM) become more common in consumer products, it is crucial to rapidly assess toxicity of unique ENM. Previous studies rarely focused on standardizing nanotoxicity testing, leading to inconsistent and irreproducible results. This study characterized a variety of ENM of different size, shape, core type, and surface charge...

  • Flesh & blood

    Creator:
    Flores, Carson
    Abstract:
    Flesh & Blood is a 118-page horror-drama screenplay about a single mother struggling to control her cannibalistic urges while caring for her young daughter and evading an increasingly suspicious detective. Two primary themes of this screenplay are control and motherhood. The protagonist of the film, Christine, grapples with controlling her...

  • Understanding Drivers of Glacier Length Variability Over the Last Millennium

    Creator:
    Huston, Alan C.
    Abstract:
    Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation, but when do such changes indicate forced climate change, and when do they indicate natural variability? In this study, we simulate the past ~1000 years of glacier length variability across the globe using the 3-stage...

  • Power Generation via a Thermoelectric Generator Driven by a Reversible Exothermic Reaction

    Creator:
    Bhatt, Renuka J.
    Abstract:
    Solar thermal energy can be stored and later converted to electrical energy using a combination of thermochemical energy storage (TCES) and a thermoelectric generator (TEG). This TEG and TCES combination illustrates a potential route for clean electricity storage from renewable energy. TCES allows for thermal energy from the sun to...

  • Particle Movement in a multi-chamber fluidized bed

    Creator:
    Tan, Chuan Hao
    Abstract:
    The goal of this project is to better characterize particle movement in a multi-channel fluidized bed. Fluidized beds are commonly used for heat transfer with the rapid fluidization and homogeneous heat distribution. By characterizing this particle flow, it would allow for an improved understanding of the heat transfer mechanisms within...

  • Constraining the origin and influence of andesite in the Purico ignimbrite, N. Chile

    Creator:
    Lapinski, Sarah L.
    Abstract:
    A feature of large continental magmatic systems is voluminous dacite ignimbrites erupted from upper crustal magma reservoirs. In the Altiplano Puna Volcanic Complex (APVC) of the Central Andes, a major ignimbrite and caldera plateau, magma systems are found to be long-lived and remarkably homogeneous requiring that they be maintained by...

  • Constraining Upper Crustal Magmas in the North Chilean Andes

    Creator:
    Lewis, Charles T.
    Abstract:
    The 4.59-4.18 Ma Caspana ignimbrite, found within the Altiplano-Puna Volcanic Complex (APVC), is the result of an ~8km3 eruption that took place during the Neogene Ignimbrite Flare-up in the N. Chilean Andes. While most of the eruptions during this flare up are large, monogenetic eruptions, the Caspana that is characterized...
