Micro-Macro Mathematical Modeling Analysis Of An Al-Air Battery, Christopher Charles Welch Jan 2020

Micro-Macro Mathematical Modeling Analysis Of An Al-Air Battery, Christopher Charles Welch

Graduate Research Theses & Dissertations

The aluminum-air battery is a very promising electrical energy storage system for portable electronics and electric vehicles because it is safe, inexpensive, and has a very high energy density. With the [EMIm]Cl-AlCl3 room-temperature ionic liquid (RTIL) electrolyte, by controlling the acidity, H2 evolution and dendrite formation are prevented and the Al2O3 passive film on the anode can be partially dissolved (cracked), so the battery’s lifespan is extended and even allows battery charging. Still, the Al2O3 passive film on the anode and Al2O3 deposition on the cathode remain issues which negatively affect battery performance. While these phenomena have been experimentally observed, …

The teachers each participated in four individual interviews, three stimulated recall interviews, and observations during the lesson studies when they taught research lessons and engaged in post-lesson discussions.

Data from the interviews and lesson study observations were analyzed using qualitative methods and through the lens of Schön’s theory of reflection. Ten sub-themes were …


Shyness Mindset And Sexual Harassment Responses Among Female College Students, Jessica Rose Winder Jan 2020

Shyness Mindset And Sexual Harassment Responses Among Female College Students, Jessica Rose Winder

Graduate Research Theses & Dissertations

Sexual harassment is a common problem that has negative consequences on society as a whole and on individual well-being. Confronting sexual harassers has been shown to be an effective response. Victims of sexual harassment are also encouraged to report harassment. Sexual harassment has been associated with internalizing responses, such as depression and decreased self-esteem. These responses could negatively influence confronting and reporting behaviors. This study draws from previous mindset research. Results from this prior research showed evidence that shyness mindset affects responses to peer victimization among adolescents and college students. This study hypothesized that shyness mindset among female college students …

Fundamental Study Of Supported Metal Catalysts Prepared By Metal In Lithium Solution For Energy Science, Haiping Xu

Graduate Research Theses & Dissertations

Electrochemical carbon dioxide reduction reaction (CO2RR) is a promising technique for energy conversion and storage from intermittent electricity sources (ie. wind and solar). By coupling electrochemical CO2 reduction (CO2R) to a renewable energy source atmospheric CO2 could be converted back into a fuel such as ethanol, or a commodity chemical such as ethanol or acetic acid. These products could then be consumed for energy or used to generate more valuable chemical products effectively removing CO2 from the atmosphere. To commercialize this process, it is highly desired to prepare catalysts that selectively reduce CO2 at low overpotential with long durability. Research …

Copper And Gold In Vapors And Liquids As A Function Of Hcl At 700°C And 100 Mpa, Corrie A. Lucchesi

Graduate Research Theses & Dissertations

Porphyry ore deposits are major sources of copper (Cu) and gold (Au) and form when a magmatic volatile phase (MVP) exsolves from a porphyritic intermediate to felsic melt and transports metals to surrounding country rock where they precipitate in an ore zone. There is a consensus that the chloride concentration of the MVP has a direct relationship to the concentration of Cu and Au in the MVP, but the role of dissolved HCl on Cu and Au concentrations has not been addressed. It is hypothesized that increasing HCl concentrations in the MVP will result in higher concentrations of Cu and …

Implementation Of A 2d Bond Based Peridynamic Fatigue Model In Fem, Kyle Mansfield Jan 2020

Implementation Of A 2d Bond Based Peridynamic Fatigue Model In Fem, Kyle Mansfield

Graduate Research Theses & Dissertations

A relatively new fracture theory known as peridynamics has been developed which uses a nonlocal theory to describe crack growth, resolving many of the issues associated to the classical continuum theory. Internal material interactions are described via a family of ‘bonds’, capable of exerting force over a macro-scale region of influence known as the horizon. Bond damage accumulates naturally due to repeated cyclic or critical loading and damage precipitates as a growing crack as bonds reach a critical damage and are severed. In the present work a modified compact tension specimen subjected to cyclic loading is modeled with the 2D …


Development Of An Electron-Beam Halo Diagnostics, Christopher James Marshall Jan 2020

Development Of An Electron-Beam Halo Diagnostics, Christopher James Marshall

Graduate Research Theses & Dissertations

Electron beam halos defined as the peripheral fraction of the beam that does not contribute to the front end application. Particles located in the halo can cause damage to the particle accelerator and lower the power and quality of the beam. Being able to measure the beam halo could provide insight on the halo-formation mechanism and ultimately will improve the overall performance and quality of the beam. A halo diagnostic was designed, and a prototype built and commissioned. The diagnostics relies on detecting optical radiation by the electron beam and masking its core to enhance the detection of the halo. …


Gender Differences In The Experience Of Power And The Underlying Mechanism Of Status, Jasmin Martinez Jan 2020

Gender Differences In The Experience Of Power And The Underlying Mechanism Of Status, Jasmin Martinez

Graduate Research Theses & Dissertations

This study examines the differential experiences of men and women with regard to the possession of power. Power—or the unequal control, influence, and access to resources, people, and things—is a byproduct of the hierarchical order that forms in a multitude of social contexts. As well as being unequally held, power is also unequally exercised. This study aims to understand the differences between men’s and women’s experience of power through the lens of another hierarchical variable: social status. One area with large implications for the impact of unequal power is within the workplace. Past literature has found that women and men …

Graduate Research Theses & Dissertations

As global climate continues to rapidly change over the coming decades, West Antarctica will continue to be a significant area of concern due to its susceptibility to marine ice sheet collapse. Past collapses during Pleistocene interglacials have been hypothesized but uncertainty exists with respect to the precise timing of specific collapse events. Drill core samples collected from the Amundsen Sea continental rise during IODP Expedition 379 allow for analysis of a more continuous record of Pleistocene glacial-interglacial cycles. Here we report paleotemperature estimates from the Amundsen Sea spanning the last 620 kyr with the objective of identifying likely late Pleistocene …


Respiratory Sinus Arrhythmia, Behavioral Inhibition/Activation, And Behavioral Response To A Distressed Infant Simulator In Emerging Adults, Erin R. Mckay Jan 2020

Respiratory Sinus Arrhythmia, Behavioral Inhibition/Activation, And Behavioral Response To A Distressed Infant Simulator In Emerging Adults, Erin R. Mckay

Graduate Research Theses & Dissertations

Caregiver sensitivity and intrusiveness during infancy are predictive of the development of self-regulation, joint-attention, and cognitive ability. However, few studies have examined predictors of caregiver responses to infant distress. Of particular note is vagal tone, specifically respiratory sinus arrhythmia (RSA), a physiological measure of top-down self-regulation. Previous work has identified a relationship between RSA, as well as other measures of caregiver self-regulation, with caregiver sensitivity and intrusiveness. The current study also examined additional predictors of caregiver responsiveness, behavioral inhibition and activation, which was conceptualized as a bottom-up system of self-regulation due to its influence on motivation and personality. It was …


Association Of Various Physiological And Fitness Markers To Body Fat Percentage In Physically Inactive Adults, Anthony Mckee Jan 2020

Association Of Various Physiological And Fitness Markers To Body Fat Percentage In Physically Inactive Adults, Anthony Mckee

Graduate Research Theses & Dissertations

Obesity can dramatically and negatively affect many aspects of normal physiological functioning. Obesity is defined as abnormal or excessive body fat accumulation that presents a risk to health. Body mass index (BMI) is a widely used approach to quantify body fat in large group settings; however, this method has significant shortcomings with accuracy and estimation. More direct measures such as bioelectrical impedance analysis (BIA) can provide a more reliable and accurate assessment of body fat mass and, therefore reduce the shortcomings of BMI when assessing possible associations with health- and performance-related variables. A plethora of research studies has been conducted …

“I Never Shared My Opinion Again”: Political Communication Apprehension And Conservative College Students, Megan Elise Montgomery Jan 2020

“I Never Shared My Opinion Again”: Political Communication Apprehension And Conservative College Students, Megan Elise Montgomery

Graduate Research Theses & Dissertations

Higher education faculty have long struggled with getting students to participate meaningfully in classroom and campus dialogues. Some students avoid participating due to fear or anxiety of communicating with others. Certain topics, such as politics, can cause higher degrees of apprehension. Political minority groups can experience greater apprehension when communicating with majority groups. One minority group in academia with the potential to self-censor is the conservative student.

This study used state-based communication apprehension (McCroskey, 1984) and political communication apprehension (PCA, Jones-Carmack, 2019) as theoretical backings to explore how conservative opinion expression and self-censorship in academic settings might change over time. …


Single-Domain Vhh Antibodies As Protein Stabilization Modules, Nourhan Mohamed Disouky Mostafa Jan 2020

Single-Domain Vhh Antibodies As Protein Stabilization Modules, Nourhan Mohamed Disouky Mostafa

Graduate Research Theses & Dissertations

VHH domains are the antigen-binding units found in heavy-chain-only antibodies from the Camelidae family (e.g., camels and llamas). They are considered a unique minimalist antibody scaffold due to the lack of a variable light chain domain. Despite having half the antigen-binding interface of conventional antibodies, these VHH antibodies bind their target antigens with affinities comparable to conventional antibodies. This project explored how flexible linkers connecting an anti-GFP VHH (αGFP VHH) domain to its antigen (EGFP) enhanced antigen stability and influenced oligomeric assembly. It was hypothesized that linking the anti-GFP VHH antibody to its target antigen (EGFP) will increase the local …
