Image Theses and Dissertations Natural and Tailored Magnesium-based Materials for Adsorptive Nutrient Recovery and Catalytic Wastewater Treatment Nutrient recovery and water reuse are two important challenges for the 21st century that are closely interlinked in the food-energy-water nexus. Two significant types of water pollution originate from inorganic nutrient encroachment of water systems due to agriculture and the emerging organic contaminants from commonly used products such as pharmaceuticals. Nutrients are lost into the watershed due to the soluble nature of conventional nitrogen and phosphorous fertilizer from runoff. View Item

Image Theses and Dissertations Development of Hybrid Polymeric/ Inorganic Ion Exchanger: Preparation, Characterization, and Environmental Applications The study involves the development of two environmental applications using hybrid polymeric/ inorganic ion exchangers. First, the hybrid polymeric ion exchangers supported hydrated zirconium oxide (HZO) nanoparticles, referred to as HIX-Zr were developed for selective removal of heavy metals and anionic ligands. Second, salt-free water softening processes were presented using three different heterogeneous cation exchanger resins along with novel regeneration schemes. View Item
Image Theses and Dissertations Characterizing targeted drug delivery and endothelial cell dynamics using in vitro blood vessel models Endothelial cells form the inner lining of blood vessels and regulate key blood vessel functions including host defense reactions, vascular smooth muscle tone, angiogenesis, and tissue fluid homeostasis. The occurrence of a pathological condition can lead to inflammation, a protective and tightly regulated response involving host cells, blood vessels and proteins. This process is promoted by circulating cytokines and other chemical mediators such as tumor necrosis factor-alpha (TNF-α), interleukins, thrombin, a few examples. View Item
Image Theses and Dissertations Strong Shock Heating of a Nanoparticle Laden Gas by a Novel Cryogenic Diaphragmless Shock Tube A new experimental facility has been developed to investigate the processes of strong shock heating of the circumstellar medium (CSM) in a supernova event. The facility is a shock tube of all-aluminum construction, and has the following three features: i) a fast action valve designed for strong shock production in lieu of a diaphragm; b) a driven section that can be cryogenically cooled to liquid nitrogen temperature; and c) an integrated metallic nanoparticle source for synthesis of a CSM by suspending metallic nanoparticles in an inert gas medium.

Image Theses and Dissertations A Deeper Understanding of Material Properties Through Computational Model Development. The pace of materials development can be significantly increased by computational models that accurately capture the characteristics of experimental materials. While advances in computational architecture have enabled researchers to calculate the properties of pure materials with high fidelity, it is often disorder of the perfect crystal that gives rise to technologically relevant properties.
