Design Principles of Transition Metal X-ide Catalysts for Electrochemical Oxygen Reduction and Evolution Reactions: In-Situ X-ray Spectroscopy Studies

Creator:: Wang, Maoyu
Abstract:: Hydrogen is the green fuel that can be produced from water through electrolysis and used via hydrogen fuel cells to generate electricity with zero carbon dioxide emission. The commercialization of electrolyzers and fuel cells is the critical step to achieving global carbon neutrality. However, it is severely hampered by the...

Development and applications of a high-throughput activity assay, using the ammonia-oxidizing bacteria Nitrosomonas europaea

Creator:: Bartow, Shannon M.
Abstract:: The rising demand on freshwater resources emphasizes the benefit of biogeochemical processes that maintain clean water by removing pollutants such as excess nitrogen. The most sensitive step in the removal of nitrogen from waterways is the oxidation of ammonia, a part of nitrification, which is carried out by ammonia oxidizing...

Device Fabrication and Characterization for Biological and Radiation Sensing

Creator:: John, Stebby Varghese
Abstract:: Amorphous indium gallium zinc oxide (IGZO) thin film transistors (TFT) has revolutionized the display industry enabling smaller pixel sizes and higher refreshing rates than traditional amorphous Si: H TFTs. These attributes of IGZO were leveraged to make a field-effect sensing (FES) platform capable of sensing various biomarkers. The sensitivity and...

Application of Self-Assembled Monolayers to InGaZnO Thin Film Transistors

Creator:: Motley, Joshua R.
Abstract:: Investigations on the application of self-assembled monolayers (SAM) to indium gallium zinc oxide (IGZO) thin film transistors (TFT) for fabrication and channel modification are presented. The back channel of IGZO thin film transistors can be modified by the absorption of self-assembled monolayers. The electrical properties of the IGZO exposed back...

Novel Approaches to Evaluate the Environmental Impacts of Nanomaterials

Creator:: Wu, Fan
Abstract:: Numerous studies have shown that some nanomaterials are highly toxic to aquatic organisms and can potentially disrupt overall community health; however, current methods to evaluate the nanomaterials environmental impacts rarely consider the environmental realism or provide sufficient detail on the impact at the community level. Here we demonstrate three approaches...

Development of Rapid Diagnostic Tools for Personal Health Monitors in the Context of Therapy Monitoring

Creator:: Wentland, Lael T.
Abstract:: Personal health monitoring tools, a subset of point-of care-diagnostics, enable more frequent testing of chronic health conditions outside of a clinic setting and can inform personalized therapy or support telehealth diagnostic capabilities. While there is evidence that regular monitoring of chronic conditions can lead to better health outcomes and lower...

Development of an anammox HDH enzyme assay to characterize heavy metal inhibition with protection tests

Creator:: Qiao, Guancheng
Abstract:: Removing nitrogen from wastewater is critical to avoid eutrophication of receiving waters. Due to its potential economic benefits, the use of anammox bacteria to remove nitrogen from wastewater is gaining in popularity. Anammox bacteria utilize NO₂- to oxidize NH₄+ to N₂. However, anammox bacteria are sensitive to a wide variety...

Carbon Aerogel-Supported Nickel and Iron for Gasification Gas Cleaning. Part I: Ammonia Adsorption

Creator:: Gomez-Capiro, Oscar, Hinkle, Adrian, Delgado, Aaron M., Fernandez, Camila, Jimenez, Romel, and Arteaga-Perez, Luis E.
Abstract:: Biomass gasification is a promising way to obtain green energy, but the gas composition makes it unsuitable for use in traditional technologies (i.e., IC engine). Gas purification over nickel and/or iron catalysts is an attractive alternative. Cellulose-based carbon aerogels (CAGs) have shown suitable physical chemical properties for use as catalyst...

Physiological response of Nitrosomonas europaea to oxytetracycline, chromium, and silver

Creator:: Schaerer, Morgan A.
Abstract:: Nitrosomonas europaea carries out the first step in the biological nitrogen removal process in wastewater treatment by oxidizing ammonia to nitrite. It has been shown to be sensitive to a wide range of contaminants. The antibiotic oxytetracycline and the heavy metals chromium and silver have been found in wastewater influent....
