Electrochemical Separation Of Multivalent Species On A Liquid Bismuth Cathode In Licl-Kcl Eutectic For Used Nuclear Fuel Reprocessing, Michael Woods Jan 2019

Electrochemical Separation Of Multivalent Species On A Liquid Bismuth Cathode In Licl-Kcl Eutectic For Used Nuclear Fuel Reprocessing, Michael Woods

Theses and Dissertations

The presence of group I/II fission products (Cs-137, Sr-90, and Ba-137) within molten salt nuclear processes degrades operational efficiencies by contributing to increased radiation levels in the case of material handling processes or to loss of criticality in the case of a reactor. While methods such as zone freezing and ion exchange have been proven for the separation of these fission products in LiCl-KCl salts, they require extra equipment and processing steps. Addition of a liquid metal electrode to molten salt media, such as the electrorefiner of a pyroprocessing scheme or the salt cleaning stage of a molten salt fast …


Modeling Electrospun Fibrous Materials, Sina Hassanpouryousefi Jan 2019

Modeling Electrospun Fibrous Materials, Sina Hassanpouryousefi

Theses and Dissertations

Electrospinning has been the focus of countless studies for the past decades for applications, including but not limited to, filtration, tissue engineering, and catalysis. Electrospinning is a one-step process for producing nano- and/or micro-fibrous materials with diameters ranging typically from 50 to 5000 nm. The simulation algorithm presented here is based on a novel mass-spring-damper (MSD) approach devised to incorporate the mechanical properties of the fibers in predicting the formation and morphology of the electrospun fibers as they travel from the needle toward the collector, and as they deposit on the substrate. This work is the first to develop a …


Engineering Of Earth-Abundant Electrochemical Catalysts, Dylan D. Rodene Jan 2019

Engineering Of Earth-Abundant Electrochemical Catalysts, Dylan D. Rodene

Theses and Dissertations

Alternative energy research into hydrogen production via water electrolysis addresses environmental and sustainability concerns associated with fossil fuel use. Renewable-powered electrolyzers are foreseen to produce hydrogen if energy and cost requirements are achieved. Electrocatalysts reduce the energy requirements of operating electrolyzers by lowering the reaction kinetics at the electrodes. Platinum group metals (PGMs) tend to be utilized as electrocatalysts but are not readily available and are expensive. Ni1-xMox alloys, as low-cost and earth-abundant transition metal nanoparticles (NPs), are emerging as promising electrocatalyst candidates to replace expensive PGM catalysts in alkaline media. Pure-phase cubic and hexagonal Ni1-x …


Cultivating A Democratic Community In The Elementary Art Classroom, Kelly Fergus Jan 2019

Cultivating A Democratic Community In The Elementary Art Classroom, Kelly Fergus

Theses and Dissertations

Cultivating a more socially just, democratic classroom community is a best pedagogical practices qualitative case study. This study is designed to explore how three Virginia elementary art teachers define and create a democratic classroom community, inside their art rooms, through the implementation of various instructional strategies within the physical, social-cultural, and pedagogical spaces of their classrooms. Such instructional strategies may include a shift in power dynamics, student-centered art, choice-based art, and a big idea/real-world issue-orientated curriculum (ex: visual culture, social justice, democratic pedagogies). Each of the three selected participants were interviewed and asked to describe their classroom practices as well …


Molecular Pharmacology Of Non-Phyto-Cannabinoid Approaches For Treatment Of Neuropathic Pain, Nadejda A. Blajkevich Jan 2019

Molecular Pharmacology Of Non-Phyto-Cannabinoid Approaches For Treatment Of Neuropathic Pain, Nadejda A. Blajkevich

Theses and Dissertations

Approximately twenty million people in United States have some form of peripheral neuropathy. It has been shown that the CB2 cannabinoid receptor is upregulated when there is peripheral nerve injury and activating the CB2 receptor produces anti-inflammatory effects that translate to a reduction in signs of “neuropathic pain” in animal models. Elevating endogenous cannabinoids by inhibiting degradative enzymes has also been used to reduce neuropathic pain signs in laboratory animal models of pain. We hypothesize that the molecular pharmacology of these two approaches can be leveraged to optimize CB1/CB2 activation to improve non-phyto-cannabinoid treatments for …

Expansion Of The Genetic Code To Include Acylated Lysine Derivatives And Photocaged Histidine, William D. Kinney Jan 2019

Expansion Of The Genetic Code To Include Acylated Lysine Derivatives And Photocaged Histidine, William D. Kinney

Theses and Dissertations

The genetic code of all known organisms is comprised of the 20 proteinogenic amino acids that serve as building blocks on a peptide chain to form a vast array of proteins. Proteins are responsible for virtually every biological process in all organisms; however, the 20 amino acids contain a limited number of functional groups that often leaves much to be desired. The lack of diversity addresses the need to increase the genetic repertoire of living cells to include a variety of amino acids with novel structural, chemical, and physical properties not found in the common 20 amino acids. In order …


Au@Tio2 Nanocomposites Synthesized By X-Ray Radiolysis As Potential Radiosensitizers, Maria C. Molina Higgins Jan 2019

Au@Tio2 Nanocomposites Synthesized By X-Ray Radiolysis As Potential Radiosensitizers, Maria C. Molina Higgins

Theses and Dissertations

Radiosensitization is a novel targeted therapy strategy where chemical compounds are being explored to enhance the sensitivity of the tissue to the effects of ionizing radiation. Among the different radiosensitizers alternatives, nanomaterials have shown promising results by enhancing tumor injury through the production of free radicals and reactive oxygen species (ROS). In this work, Gold-supported titania (Au@TiO2) nanocomposites were synthesized through an innovative strategy using X-ray irradiation, and their potential as radiosensitizers was investigated. Radiosensitization of Au@TiO2 nanocomposites was assessed by monitoring the decomposition of Methylene Blue (MB) under X-ray irradiation in the presence of the nanomaterial. …


Down By Law: A Demographic And Geographic Analysis Of Those Killed By Police, Scott W. Murrah Jan 2019

Down By Law: A Demographic And Geographic Analysis Of Those Killed By Police, Scott W. Murrah

Theses and Dissertations

After the rebellion over the killing of Michael Brown, the US Justice Department reported that over-policing for the sake of monetary extraction was taking place in Ferguson, MO, with non-White and people in poverty being disproportionately targeted at the hands of the police. And while it has been shown to be present within the Ferguson community, this extraction and targeting by police is not a geographically isolated occurrence. Based on previous research, a racialized, economic-based system of oppression goes hand-in-hand with policing. But how do the qualities of these geographies affect the prominence and location of police violence on a …

Older Artists And Acknowledging Ageism, Liz Langdon Dec 2018

Older Artists And Acknowledging Ageism, Liz Langdon

International Journal of Lifelong Learning in Art Education

Intergenerational (IG) learning has the potential to reinforce ageist ideas, through the culturally produced binary of old and young which often describes IG learning. This research with older artists revealed implicit age bias associated with a modernist tradition in art education which minimized the value of art production viewed as feminine. Language associated with ageism shares the descriptors of the feminine and seep into our perceptions. Cooperative action research with multi-age participants facilitated personal growth and through critical reflection, implicit ageism revealed in the researcher’s prior perspective is revealed.


Intergenerational Narratives: The Personal Is Professional, Jodi Kushins, Amy B. Snider Dec 2018

Intergenerational Narratives: The Personal Is Professional, Jodi Kushins, Amy B. Snider

International Journal of Lifelong Learning in Art Education

What began as a teacher-student relationship between educators Amy Brook Snider and Jodi Kushins has developed into a friendship and working partnership. At first, they did not consider their continuing long-distance connection as intergenerational. They shared experiences and exchanged ideas oblivious to the great difference in their ages. But as online tools, research, and communication emerged as a central focus of Jodi’s life and teaching, they became aware that this development might lead to an intergenerational digital divide between them. In order to explore their different responses to what has been called screen culture, they brought back their puppet alter …


Leaf-Ing A Legacy, Susan R. Whiteland Dec 2018

Leaf-Ing A Legacy, Susan R. Whiteland

International Journal of Lifelong Learning in Art Education

Leaf-ing a Legacy is the story of a university art education class that joined with an elementary classroom and residents in a long term health/rehabilitative center through a service-learning project that utilized digital technology and art making in a problem-based learning format to explore the concept of legacy. Evidence was found that the experience promoted socio-emotional learning and fostered the building of socio-emotional capital for the participants involved.
