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...

Analyzing the use of the acellular DCFH assay as a means of determining oxidative stress induced in zebrafish embryos exposed to lanthanide oxide nanoparticles

Creator:: Engstrom, Arek
Abstract:: The ability of nanoparticles (NPs) to induce oxidative stress on organisms has been linked to NP cytotoxicity and genotoxicity for a variety of organisms. One proposed mechanism of this increased oxidative stress is the ability of NPs to generate reactive oxygen species (ROS). Due to the dynamic nature and small...

Environmental Transformations of Nanoparticles in Natural Water Systems using a Hydrophobic and Hydrophilic Dye Assay

Creator:: Turnquist, Macklin C.
Abstract:: Nanoparticles (NPs) are generally defined as particles <100 nanometers (nm) in size in one dimension. Despite increasing industrial usage of TiO2 NPs in sunscreens, cosmetics, and water remediation little is known of their environmental behavior. The primary goal of this research was to develop a rapid method for determining the...

Creator:: Osborn, Lauren A.
Abstract:: Collaboration is crucial when advancing in scientific research. One person cannot study all aspects of a system. That is why it is important for the scientific community to communicate with each other and stay updated on research being conducted in other labs around the world. In my research, I was...

A Multivariate Analysis of Pacific Arctic Surface Waters

Creator:: Bryant, Aleesa
Abstract:: The Pacific Arctic is undergoing rapid biogeochemical changes in response to warming air temperatures caused by climate forcing. This is manifesting as changes in seasonal sea ice thickness and sea ice extent, as well as changes in primary production within surface waters. The data and samples analyzed here were collected...

High-resolution Biological Net Community Production in the Pacific-influenced Arctic: A Multi-method Comparison

Creator:: Cynar, Haley
Abstract:: Patterns of primary productivity in the Arctic are expected to change with continued warming, yet productivity measurements are historically limited, both spatially and temporally. An established method of measuring net biological oxygen production, which can be used to estimate net community production (NCP) rates, is with an equilibrated inlet mass...

Environmental Transformations in Hydrophobicity of TiO2 P-25 Nanoparticles in Alsea River Waters

Creator:: Boenisch, Kylie
Abstract:: Hydrophobic titanium dioxide (TiO2) nanoparticles (NPs) are prevalent in industry and manufacturing. They are known for their white pigmentation, are found in sunscreens, paints, cosmetics, and are frequently used in wastewater treatment. Understanding the physicochemical properties of TiO2 P-25 NPs, such as hydrophobicity, are essential when determining their fate, transport,...

Quantification of Lithium via Redox Titration and pH Titration – A Method Comparison

Creator:: Hebert, Joseph J.
Abstract:: Lithium serves an unparalleled role for high energy-density storage applications and is vital for the continued advancement of the world economy. However, global supply is heavily reliant on lithium deposits situated in select locations, creating unpredictability in the price and concerns for the sustained production of the resource. Additionally, future...

Functional status and fall risk among older adult participants in community-based exercise programs : Do Better Bones & Balance® participants outperform their peers?

Creator:: Trevis, Lauren E.
Abstract:: Purpose: This study examines the relationship between community-based fitness class participation and risk for falls in adults aged 55 or older. Our aim was to compare scores on fall risk factors between community-based Better Bones & Balance® (BBB) participants and active peers who engage in other (non-BBB) community-based fitness classes....

Diversity and composition of mammal and bird communities in northern Pantanal, Brazil

Creator:: Coe, Lauren E.
Abstract:: The Pantanal is one of the largest wetlands in the world, covering 195,000 km2 across Brazil, Bolivia and Paraguay. It has a unique annual flooding regime with the majority of land being completely inundated during the wet season, which provides important habitat for threatened species such as jaguars (Panthera onca)...
