Studies on effect of stabilizers, chelators and inherent periodicity on nanoparticle antioxidant activity

Creator:: Zhou, Zheng
Abstract:: The level of reactive oxygen species (ROS) is tightly regulated in biological systems as overproduction can lead to oxidative stress and result in a number of diseases. Due to its negative effects, antioxidants are studied and used against ROS in medicine, pharmaceuticals and therapeutics. Because of issues with the uptake...

Molecular and Kinetic Characterization of Anammox Bacteria Enrichments and Determination of the Suitability of Anammox for Landfill Leachate Treatment

Creator:: Sultana, Sharmin
Abstract:: Anaerobic ammonium oxidation (anammox) has recently appeared as a promising approach for removing nitrogen from landfill leachates because it requires less oxygen and no organic carbon compared to traditional nitrification-denitrification system, and it produces low sludge volumes, thereby reducing operating and biological sludge disposal costs by over 60%. Anammox bacteria...

Exploration of Simultaneous Anammox and Denitrification (SAD) Biofilm Processes for Nitrogen Removal

Creator:: Hilliard, Richard F.
Abstract:: Anammox (anaerobic ammonium oxidation) bacteria are capable of providing low-cost nitrogen removal for numerous types of wastewaters. However, low growth rates cause long startup-times and inhibition by oxygen and metabolic substrates necessitate close process control to maintain performance. Incorporation of Simultaneous Anammox and Denitrification (SAD) into constructed wetlands could provide...

Exploring the Anaerobic Co-digestion of Food Waste, Brewery Waste, and Fats, Oils, and Greases through Biomethane Potential Testing and Response Surface Methodology

Creator:: Liberman, Madalyn R.
Abstract:: Food waste (FW), brewery waste (BW), and fats, oils, and greases (FOG), are prevalent waste streams in municipalities across the country, particularly in the Pacific Northwest (PNW). Anaerobic digestion (AD), the microbial-mediated transformation of organic waste into methane-rich biogas, offers a sustainable, energy-generating, waste management solution for these wastes. Anaerobic...

Addressing Persistent Challenges in Nanotoxicology Exposures : Techniques for in situ Characterization

Creator:: Crandon, Lauren E.
Abstract:: Nanoparticles (NPs), defined by their size (1-100 nm), are increasingly incorporated into commercial and industrial products due to their high surface area and unique properties. They can be designed for specific applications by manipulating composition, size, shape, and surface functionalization. As NP production and complexity increases, there is a need...

Photochemical reduction of carbon dioxide in aqueous and ionic liquid solutions in a microreactor with TiO₂ catalyst; experiment and modeling

Creator:: Campbell, Travis J.
Abstract:: Microtechnology was used to study the chemical reduction of dissolved carbon dioxide into useful products. A novel TiO₂ photocatalyst was used to activate the reaction under ultraviolet irradiation. CO₂ was dissolved in aqueous and 50% BMIM-BF₄ (ionic liquid) solutions. The introduction of an ionic liquid increased the solubility of CO₂...

Development of traceable metal oxide nanoparticles for examining environmental fate and transport

Creator:: Rowbotham, Brian
Abstract:: The fate and transport of engineered nanoparticles (ENPs) such as titanium dioxide (TiO₂) are of concern due to their increasing use in consumer products. Although analytical methods for detection and quantification of ENPs in environmental matrices are being developed, these methods are difficult, time consuming, and not easily validated for...

Evaluation of amorphous oxide semiconductors for thin film transistors (TFTs) and resistive random access memory (RRAM) applications

Creator:: Rajachidambaram, Jaana Saranya
Abstract:: Thin-film transistors (TFTs) are primarily used as a switching element in liquid crystal displays. Currently, amorphous silicon is the dominant TFT technology for displays, but higher performance TFTs will become necessary to enable ultra-definition resolution high-frequency large-area displays. Amorphous zinc tin oxide (ZTO) TFTs were fabricated by RF magnetron sputter...
