Investigation of f-Element Extraction and Ligand Association in the ALSEP Extraction System for Used Nuclear Fuel Reprocessing

Creator:: Holfeltz, Vanessa E.
Abstract:: Effective separation of lanthanides (Ln) from the minor actinides (MA) is a crucial technical challenge to closing the nuclear fuel cycle. This separation is a necessary prerequisite to transmute long-lived isotopes of Am and Cm, which will allow a reduction of the repository volume, thermal load, and radiological toxicity of...

Organic Phase Inter-Ligand and Metal-Ligand Speciation in TALSPEAK and ALSEP Solvent Extraction Systems

Creator:: Gullekson, Brian J.
Abstract:: Partitioning of trivalent actinides (in particular, americium and curium) from the fission produced light lanthanides is a major concern of used nuclear fuel reprocessing for the purposes of waste disposal. Several solvent extraction processes have been developed to address these chemically difficult separations. The historically employed TALSPEAK Process utilizes di-2-ethylhexyl...

Examination of Multiple Air Pollutant Exposure, the Food Environment, and Low Birth Weight in Los Angeles, County

Creator:: Coker, Eric S.
Abstract:: Exposure to urban outdoor air pollution is ubiquitous and low birth weight represents an important health disparity in the United States. While previous research suggests that exposure to outdoor air pollutants are associated with term low birth weight, few studies have evaluated the effects of multipollutant outdoor air exposures or...

Childhood cancer and spatial analyses of benzene exposure in Texas

Creator:: Roberts, Mark T.
Abstract:: Childhood cancers are rare diseases that affect 188 children in Texas for every million born. Leukemia is the most common childhood cancer and accounts for roughly one third of childhood cancer cases. However, it is estimated that only 10% of childhood cancer cases can be explained by known risk factors....

Designing surveys to investigate the impacts of wildfire smoke on human health

Creator:: Attridge, Samuel J.
Abstract:: Wildfires are increasing in frequency. One area of research interest centers on the pollutants within wildfire smoke, including but not limited to particulate matter and polycyclic aromatic hydrocarbons. These chemicals are associated with exacerbation of respiratory, cardiovascular, dermatological, reproductive, oncological, gastrointestinal, and infectious conditions. As wildfires becoming increasingly prevalent, it...

Characterizing PM2.5 with Different Source Contributions

Creator:: Perez, Allison Mae S.
Abstract:: Ubiquitous fine particulate matter (PM2.5) exposures significantly impact global public health, yet little is known about the mechanisms causing these known adverse health effects. Oxidative stress due to PM2.5 associated chemical constituents, such as polycyclic aromatic hydrocarbons (PAHs), is a proposed possible mechanism for PM2.5 mediated health effects. Variations in...

Classifying polycyclic aromatic hydrocarbon bioactivities using phenotypic screening and transcriptomics in the developmental zebrafish model

Creator:: Geier, Mitra Celestine
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental contaminants that occur in complex mixtures. These environmental mixtures can consist of both parent PAHs and their derivatives. Several parent PAHs are known or suspected mutagens and/or carcinogens, and a handful of PAH derivatives are known to be more potent mutagens and/or carcinogens...

Assessing Exposures and Simplifying Complex Mixtures of SVOCs for Hazard Characterization using Alternative Model Systems

Creator:: Rivera, Brianna N.
Abstract:: Throughout their lifetime individuals are exposed to complex mixtures of chemicals. The study of chemical mixtures is an internationally recognized research priority, but seemingly complex challenge. To reduce the intricacy of studying mixtures, researchers have identified different prioritization methods based on exposure or the toxicity of chemicals. However, understanding the...

Understanding the future of PFAS policy and management : a comparative study between two regions – the Pacific Northwest and the Great Lakes Region

Creator:: Tran, Danielle N.
Abstract:: In the past fifty years, per- and polyfluoroalkyl substances (PFASs) have become alarming global pollutants. In 2019, the United States (U.S.) Environmental Protection Agency (EPA) ultimately classified them as emerging contaminants and established an action plan to address PFAS and protect public health through developing, identifying, monitoring, and remediating current...

New Inorganic Pigments from Mineral Structures

Creator:: Schettini Mejia, Carlo A.
Abstract:: The discovery of new blue pigments is a field of great interest, as commercially available pigments present properties that make them undesirable such as poor sustainability, cost, and stability. By researching solid solutions with the melilite structure, we discovered a new solid solution Sr2Zn1-xNixGe2O7, with 0.1 ≤ x ≤ 0.6,...
