An Exploration of the Black Female Cosplay Experience

Cosplay is the practice of dressing up as a fictional character whether it is from a television show, video game, or even a book series. Many people participate in cosplay to show their dedication or admiration for their favorite character and sometimes they cosplay a character that helps reflect their own character or personality. This thesis will mainly focus on the experience of being a Black female cosplayer in pop culture, social media, conventions, and other places where people can share and communicate. In this research, participants' answers about their experiences were centered around their inspiration to start cosplaying, their ways of alternating their cosplays to their liking, participation experience, memorable experiences, and what they would like others to know about being a Black female cosplayer. Overall, the participants express that they have a bond with their cosplays and enjoy it despite the issues of exclusion.

A Persecuted to Minority to Wealthy Merchants and Planters: A Study of a Huguenot Family and Shifts in Identity

This project takes a look at an interwoven system of familial, religious, social, and economic ties known as the Protestant International. By analyzing genealogies, correspondence, business records, and transactions of the Mazyck Family, it is seen that these international connections often led to the material success of these families. This project also takes a look at how the Protestant International aided in shifting the vast majority of Huguenots’ identity from being religiously persecuted refugees to being wealthy merchants and planters who formed trade relations, both domestically and internationally.

College Students’ Perceptions of the Efficacy of Different Strategies to Reduce the Rate of Abortion

This study examines college students’ perceptions of different strategies and the efficacy of those strategies to reduce the rates of abortions. Factors such as comprehensive, medically accurate sex education, widespread accessibility and affordability of contraception, and affordable and accessible pre-natal care are all factors that the literature has established lower the rates of abortions. Factors such as waiting periods of 24 hours or more to perform a surgical abortion, restricting state funding for abortions, and legal bans of abortions altogether are factors that do not reduce the rates of abortions (Medoff, 2015); they may even be counterproductive to their original purpose and cause the number of abortions to rise, not fall. This study uses a mixed methods approach of qualitative and quantitative questions including a Likert-type scale, to measure participants’ perceptions against what the peer reviewed data knows to be effective in lowering abortion rates. The data had shown that sex education, contraception and prenatal care are factors that these college students thought would lower the rates of abortion which directly links to what the literature lists as factors that will reduce the rates or abortion. However, my participants thought bans on abortion and restrictive laws would lower the rates which we know to be false according to the literature.

Blank Spaces: An Exploration of Memory and Nostalgia through Mixed Media

Blank Spaces explores the way childhood nostalgia manifests in the physical world through the creation of mixed media pieces. The experimentation with different mediums in my work, such as painting, ceramics, and animation, is emblematic of childhood creative play. These mixed media artworks showcase how memories recalled from the past can influence our interpretation of the present. The familial connection to family and culture, represented through manipulated old family photographs and imaginary renderings of stories, blends representational imagery with fantasy; my art examines the movement of those memories in the “blank spaces” of the mind. The thesis adds to the conversation of personal truth regarding the recollection of family memories and discusses mortality by symbolizing the impermanence of people and time.

Targeted Sanctions Against Human Rights Violators: A Question of Efficacy

Human rights violations occur all too frequently, with authoritarian regimes at the forefront of abuses. Countries that respect human rights engage in various initiatives, one such example being targeted sanctions to try and stem the tide of human suffering at the hands of unscrupulous dictators. Currently, Uyghurs are victims of genocide in China, dissidents in countries such as Russia and Belarus are falsely imprisoned, and individuals in Saudi Arabia are persecuted and imprisoned solely for advocating for freedom of speech and equality for women. Each of these countries have been the subject of sanctions. This paper seeks to answer the question: to what extent are targeted sanctions effective when applied to states or individuals when they are deemed guilty of human rights violations? I argue that the sanctions are rendered ineffective because the targeted state does not manifest any positive behavior changes regarding the treatment of its citizens. This is revealed in the authoritarian behavior of state leaders who believe that only they are qualified to run their countries. I conduct a mixed methods research approach combining a broad quantitative analysis of a country’s human rights practices with a narrow qualitative analysis of the authoritarian regime of the Russian Federation and find support for my argument.

Restricted at Home, Impeded Abroad: A Study of Domestic Human Rights Practices and Women’s Global Economic Power

To what extent does the practice of human rights as universal or culturally relative impact women’s status in the global economy? While there is already evidence to show how women have less power in countries that practice culturally relative human rights, this study aims to explore how the domestic practice of human rights influences women’s global power through an analysis of women’s financial inclusion. Using a cross-national, quantitative analysis, I show that human rights practices in the domestic arena directly impact the economic power of women in the global economy. When human rights practices at home are more universal in nature, women’s financial inclusion across the global economy is higher, yet, when domestic practices are more culturally relative, women’s financial inclusion suffers, impeding their ability to compete in the international economy. While scholars have presented many valid arguments in favor of culturally relative human rights practices, I argue that given the rise of globalization and the dire need for women to gain more economic power to be competitive in the global marketplace, domestic practices of human rights no longer remain isolated, and thus, must embrace universal practices as a whole. This study is important because it reinforces the concept and importance of universal human rights while adding to the growing body of work on the power of women around the world.

Big Tech: Antitrust Paradox or Solvable?

From sending emails, to online ordering, or simply watching Netflix at home, Big Tech has invaded almost every aspect of our modern twenty-first century lives. As technology brought innovation and convenience, it also brought upon a legal regulatory challenge for federal systems, such as the United States (US) and the European Union (EU). In this thesis, I will use comparative analysis in the cases of antitrust law in the United States and European Union competition law. Then, I investigate if regulation actually accomplishes its mission – protecting consumer welfare. The consumer welfare standard has been used in both the US and the EU since 1970’s. However, there is a lack of empirical evidence to show how lower or higher regulation affects consumer welfare and how consumers feel about their own welfare. In this thesis, I want to fill the gap in empirical evidence by looking at ways to calculate consumer welfare by listening to the personal experiences of the American public. I argue that increased regulation of Big Tech will bring an increase in consumer welfare.

Juries and the Effects of Priming

How do jurors' responses to Non-White defendants in the Criminal Courts change when they are primed to think about police discrimination? There are general disparities within the Criminal Justice System of the United States that negatively impact racial minorities. This paper discusses these general disparities within the Criminal Justice System of the United States. Black and Latinx individuals are charged and sentenced for crimes involving drugs at higher rates than Whites. They are also more likely to face the death penalty or longer sentences. I look at whether or not priming jury members to think about police discrimination will decrease the likelihood that they declare Non-White defendants guilty. I complete an experimental survey to examine the effects priming has on potential jury members' views of the level of guiltiness of Non-White defendants.

The Impact of Academic Development Structures on Self-Perception: Honors vs Non-Honors University Students

The purpose of the current study was to determine if there were variations in the self-perceptions of honors and non-honors collegiate students in areas of academic and non-academic self-concept. This research was important as it provides emphasis on an understudied population as well as gathers a deeper understanding of intricacies related to self-concept by incorporating comprehensive investigative measures. A sample of 236 students (72.6% female, 65.7% White, ages 18-51) took an online survey consisting of questions related to self-concept. By utilizing a series of two-tailed, independent samples t-tests we examined the differences between student self-perceptions of self-concept. Results indicated that honors students had statistically significantly higher academic self-concepts than non-honors students. Both groups of students scored similarly across social self-concepts, however, non-honors students had higher perceptions of their physical self-concepts. These findings will provide new insights into how honors enrollment impacts the formation of self-image.

Investigating the Effects of Culturally Responsive Physicians on Treatment Seeking Behaviors

People from marginalized communities often receive fewer healthcare opportunities than people who are not from marginalized communities (Copeland, 2016), which contributes to health disparities. Physician cultural responsiveness is the willingness to seek out knowledge and adapt to different cultural beliefs (Ring, 2009). The present study investigated how the presence of cultural responsiveness in fictional yelp reviews impacted Black and White participants’ willingness to seek treatment and evaluate physicians favorably. Nineteen Black participants and thirty-nine White participants who indicated they would use an OB/GYN participated in this study. All participants read twelve Yelp-like reviews about OB/GYN’s: six had culturally responsive characteristics to them; six did not have culturally responsive characteristics. After each review, participants indicated how much they anticipated liking the physician, the importance of the physician’s characteristics, the likelihood that they would leave a review of the doctor, the likelihood they would recommend the physician, and the likelihood of seeking treatment from this doctor. Five mixed model ANOVAs were conducted with the alpha level adjusted to .01. Compared to White participants, Black participants liked and were more likely to seek treatment from culturally responsive physicians. White participants were more likely to recommend, seek treatment from, and report higher importance of character for non-culturally responsive physicians than culturally responsive physicians. Further research should investigate the factors for why these patterns of results emerged. Additionally, it is important to note our study has a small sample size, however, we believe if replicated with a larger sample size, the results would be consistent.

Hiring Decisions: Impacts of Applicant Gender and Social Media Presence

Studies show that hiring decisions can be influenced by an applicant’s social media profile (Broughton et al., 2013) as well as their gender (Garcia-Retamero & Lopez-Zafra, 2009). Women, compared to men, are more likely to face hiring discrimination (Garcia-Retamero & Lopez-Zafra, 2009) and many hiring managers tend to look at an applicant’s social media profiles for additional information during the hiring process (Broughton et al., 2013). There is a lack of substantial research on the combination of these two factors. This study examined the effects of gender and social media type on hiring decisions.

The Mediating Role of Mental Health on Academic Performance Among College Women Who Have Experienced Sexual Assault

The current study analyzed the mediating role of mental health on academic performance among college women who have experienced sexual assault. The purpose of this research was to acknowledge the impacts that sexual assault experiences may have on the college experience. A total of 241 undergraduate students participated in the study. Participants were college aged, ranging from 18-36 (90.5% female, 59.2% White, 28.1% Black/African American). Participants completed an online survey that evaluated their sexual assault experience, depression, and academic performance. Using Baron and Kenny’s (1986) mediation model, it was found that as participants reported higher instances of sexual assault experience, they tended to report lower academic performance, and this relationship was mediated by increased depression symptoms. These findings contribute new information to the current literature and further stress the importance of preventing instances of sexual assault on college campuses and supporting victims due to psychological and academic consequences.

Math Modeling and Simulation of a Chasing Game

This study is based on a chasing game between two objects, one being a chaser and the other a moving target. For this problem, we assume that the chaser is always moving in a direction such that it is in line with the target. To put that assumption into a mathematical model, we used a system of differential equations to map the trajectory of the chaser. We used the fourth order Runge-Kutta method, a highly accurate method of solving ordinary differential equations, to solve these equations numerically. The goal of this project is to develop a mathematical model to precisely predict the trajectory of the chaser as it moves towards the target. We will use this model to find the minimum speed of the chaser at a specified target speed with three other fixed parameters: target path, initial dog position, and a vertical boundary. We hope to identify the impact of different system parameters on the outcome of the chasing game. This problem can be further worked on to predict minimum speeds in various chasing scenarios and could potentially be linked to the design of tactical guided missiles.

Synthesis of Trifluoromethyl Ketones by (Diethylamino) Sulfur Trifluoride (DAST)- Mediated Nucleophilic Trifluoromethylation of Benzoic Acids

Within the past few decades, the presence of fluorine containing organic molecules has increased significantly. Many of the current industrial production methods are not cost-effective, practical, or inherently safe. This work describes a new methodology for the synthesis of trifluoromethyl ketones. Our new method involves the use of benzoic acid and trifluoromethyl trimethylsilane (TMSCF 3 ) as starting materials along with diethylamino sulfur trifluoride (DAST) as a reagent to obtain moderate to good yields of expected products in a short reaction times.

Synthesis, Characterization and Cell Viability of Novel Tripodal Amines

Cancer, over the years, has become a much more prevalent focus for the scientific community. Organizations and laboratories all over the world have spent countless hours searching for a cure, trying to learn more about what makes cancer so powerful and what is the best way to stop its growth. Iron-chelation drugs were already on the market, and it was shown that they did have the ability to act as both iron-chelators and anticancer drugs. Most of these iron-chelating drugs are not as effective at killing cancer cells as the medical field desires. Novel iron-chelating tris-indolyl derivatives, GSO2, GSO4 and GSO6, were synthesized and tested for their potential anti-cancer properties. These compounds were characterized using both melting points and NMR. Apoptosis was the chosen method for cell death of the PC3 cells. The compounds, GSO2 and GSO4 did show promising results when tested on human prostate cancer cell lines. The success of these compounds does sanction further research into apoptosis of other human cancer cell lines.

Nanoparticle Conjugated Photosensitizer for Targeted Photodynamic Inactivation of Cancer Cells

Photodynamic therapy (PDT) is considered to be a potential replacement for traditional methods of chemotherapy. It includes the administration of photosensitizing agents (PS), which generate reactive oxygen species (ROS) upon excitation at a specific wavelength. In the present work, a rhodamine derivative was used as the PS. In general, rhodamine derivatives carry out cytotoxic reactions on photoexcitation by electron transfer reactions with folic acid within cells, making them a favorable PS. However, rhodamines often experience poor water solubility which limits their applications in biological environments. Additionally, the process of PDT also requires a high accumulation of photosensitizer. To overcome the challenge of the aqueous compatibility of rhodamine compound while retaining its specific functioning in cells, this project focused on developing a nanocarrier system to help deliver those dyes to the cancer targets. The present work studies the nature of the interactions between gold nanoparticles (GNPs) serving as a nanocarrier system and a rhodamine derivative as part of a further characterization study. The following research includes the synthesis of GNPs, with particle diameter 16-30 nm verified using Dynamic Light Scattering spectroscopy and UV-Vis, that form a nanocomposite with rhodamine derivatives and undergo immobilization over time. The dye-nanoparticle pair was incubated for different time periods (up to seven days) and characterized through UV-vis and fluorescence spectroscopies. This experimentation showed GNP conjugated rhodamine dye could show higher efficacy in killing cancer cells during PDT, but when combined have viability limited to approximately 48 hours.

How Formal Music Training Affects Executive Functions in Middle School Band Students

My thesis project explored the relationship between a formal music training experience and executive functions in a middle school band classroom. Executive functions are working memory, inhibition, and cognitive flexibility which allow us to gain and focus our attention on specific tasks. Participants in the study were two groups of middle school students: a sixth grade class with no previous musical experience and an eighth grade class with two years of band classes. I measured changes in students' overall success on cognitive tests over a two month span to observe at what point music training begins to impact executive functions. I will use these results to develop hypotheses about why that occurs.

The Psychological Effects of the Voice Change in Female Students and the Implications of Current Pedagogy

The voice change process is a treacherous time for anyone, and choral music educators are tasked with helping their singers to navigate this time. In comparison to the male voice change, the female voice change process is underrepresented in literature and often ignored in classrooms (Sweet, 2018). The purpose of this study is to explore the psychological effects of the voice change process in female students and identify current pedagogical trends in voice change education as used by current secondary choral music educators. Participants included a) choral music education students who experienced a female voice change and b) current secondary choral music educators. Choral music education students responded to a background survey which collected demographic information and voice change process self-efficacy data. Selected informants underwent individual semi-structured interviews about their voice change experience. Current secondary choral music educators responded to an attitudinal and pedagogical survey of both Likert-type and open-ended prompts. Data were analyzed using descriptive statistics for surveys and an emergent coding process to determine themes in interviews. Findings from choral music education students included a range of emotion and confidence levels associated with the voice change process. An overarching theme for these informants included the aspects of typical adolescent psychological development. Additionally, secondary choral music educators showed differences in levels of preparation and confidence in dealing with the female voice change. These findings are most likely directly related to the lack of Social Emotional Learning techniques in past and current classrooms.

Diversity of Choral Literature and the Selection Process

In music education, festival events are a chance to receive feedback from experts in the field. Often, these events have literature lists from which directors are required to choose literature for the event. With choral festivals being so prevalent in music education, the literature lists provided to choral music educators have a major impact on young singers. Literature selection can be intense for choral music educators who decide what factors to consider when selecting literature. The purpose of this study was to explore and analyze the diversity of choral literature through analysis of the Georgia Large Group Performance Evaluation (LGPE) list while also gaining a better understanding of literature selection processes through interviews. My research questions were the following: What choral literature is most prevalent in the LGPE list in Georgia? How do choral music educators approach the process of choosing literature, and what role does diversity play in that process? The sequential explanatory mixed methods approach was used. An analysis of the diversity of choral festival literature on the LGPE list was collected, followed by semi-structured interviews in which a broader perspective on the literature selection process was gained. Informants, chosen by convenience sampling, were required to be current choral music educators with at least one full year of experience. Interviews were transcribed and analyzed using a two-step inductive coding process. Data were triangulated by way of member checking the transcripts. Applications for this research include choral music educators being more aware of the diversity of their festival literature.

Examining The Role Of Instagram As A Public Relations Tool In The Real Estate Industry

Nearly all social activities are carried out on some sort of technology whether it be a cellphone or laptop, and people throughout the world are interacting with each other and forming communities based on certain factors like interests and geographic location. Companies are becoming more reliant on the incorporation of technology and the social network sites, also known as SNS, like TikTok and Instagram into their public relations strategies. Due to the nature of Instagram as image and video sharing platform, many real estate agencies have turned to Instagram to create mutually beneficial relationships with their clients and targeted public. This study evaluated the ways five real estate agencies located in Bulloch County used Instagram to create these relations while also maintaining these relationships through the content being posted and the use of features offered on Instagram.

How Nationality Influences Development in Youth Soccer

The primary purpose of the study was to identify tactics to improve youth soccer development in the United States, which will positively impact future American soccer players. The thesis analyzes how factors related to nationality influence development in youth soccer and identifies the fundamental differences in youth soccer development between male and female American and international soccer players. The proposal delineates why player development is paramount towards the success of a country`s national team, more so than the population or wealth of a nation. The research study used a structured survey-based approach for statistically testing hypotheses. The targeted group for the study was National Collegiate Athletic Association (NCAA) Division I and NCAA Division II collegiate soccer players. NCAA Division I and II are considered to be elite amateur levels in the United States. Therefore, the players mostly played for quality youth clubs and academies from around the world. Qualtrics was used to create and distribute the survey, which was distributed to numerous NCAA Division I and II men's and women's soccer players across the U.S. at various programs, homing in on how nationality influences development in youth soccer.

Myths, Misconceptions, and Misrepresentations: An Examination of Erroneous Human Trafficking Beliefs

Human trafficking is a crime that effects people all over the globe and an estimated 24.9 million people are currently being exploited through some form of human trafficking. Despite its prevalence, there are a variety of myths regarding human trafficking that are commonly believed by the public. The proliferation of these myths can have damaging effects and ultimately prevent survivors from receiving the help they need. The aim of this study is to discover factors that lead to the belief of these myths about human trafficking. To uncover these factors, a survey was administered in October 2020 and completed by 924 respondents. Results reveal fairly widespread belief in common human trafficking myths; however, these beliefs were moderated by criminal justice exposure.

Analyzing Working Memory and Inhibitory Control Deficits in College Students With and Without Attention-deficit/ Hyperactivity Disorder

Attention-Deficit Hyperactivity Disorder (ADHD) is a disorder that affects approximately 3%-6% of adults. However, that number includes college students who require working memory and inhibitory control to be successful. (Green & Rabiner, 2012) The present study investigated deficits in executive function, specifically working memory and inhibitory control, in college students who are diagnosed with Attention-Deficit/Hyperactivity Disorder relative to their classmates who are not diagnosed with ADHD. The purpose of this research is to contribute to the limited knowledge about college students with ADHD, precisely their challenges with inhibitory control and working memory, in comparison to their classmates who do not live with this mental health diagnosis. A better understanding of the certain functional deficits that accompany ADHD, and the college student population, may inform augmentation of interventions to increase academic performance and promote a positive college outcome for this population. (Woltering, 2013) Knowledge brings about awareness, awareness brings about empathy, and empathy will allow for students who struggle relative to their college classmates to be heard. In order to investigate these deficits, the ADEXI scale will be implemented. This scale has shown to be a reliable instrument in distinguishing between adults with ADHD relative to nonADHD controls while specifically investigating deficits in working memory and inhibitory control. (Holst & Thorell, 2018, Sjöwall, 2019, Thorell & Nyberg, 2008) In consideration of current research, an expected hypothesis is that college students diagnosed with ADHD will score higher on the self-reported ADEXI scale relative to the comparison group, illustrating a relationship between executive dysfunction and college students with ADHD.

Nursing Students' Perceptions of Stress and Anxiety in Relation to Academic and Clinical Demands

The negative consequences of stress can be felt across multiple systems of the body with both physical and psychological ramifications. Nursing students are typically known to have high stress levels. Stress in nursing students can arise from academic pressures, clinical experiences, and the attempt to balance self-care and personal lives with the demands of a rigorous degree program. For this project, I surveyed collegiate nursing students to determine their perceptions of factors relating to their stress and anxiety levels. Participants were presented with both quantitative and qualitative questions. Data collection was carried out using an online Qualtrics survey made available to nursing students on the Statesboro campus of Georgia Southern University. Data analysis was completed using the Qualtrics software. It was determined that this population experiences high levels of stress and anxiety and it is imperative to identify effective ways to alleviate those levels. The goal of this research is to shed light on the importance of self-care and effective stress management techniques for nursing students. In addition, it is my hope that nursing professors and instructors can use this research to gain insight into how they can best support their students as they progress through the program.

From the Other Side: Nurses’ Perception on the Use of Negative Pressure Wound Therapy in Clinical Setting

Negative Pressure Wound Therapy (NPWT) is a revolutionary technology being used increasingly frequently in clinical settings across the United States. Though there has been extensive research on the efficacy and successfulness of NPWT medically and otherwise, there has been little research regarding the healthcare providers’ perception of use of “wound-vacs,” the device used for NPWT. As new techniques and/or devices are made available for use in a clinical setting, the burden to learn and advance accordingly falls upon providers. The administration of NPWT is wholly reliant on nurses as they are the ones to apply the dressing, change it and document the progress; therefore, the burden is highest on nurses for application of NPWT. A study was conducted with the nurses at East Georgia Regional Medical Centre in Statesboro, Georgia exploring the time, skill, and educational restraints related to learning a new technique and successfully administering it. Using a mixed-methodology approach, five voluntary participating nurses completed a self-paced survey answering questions about the use of NPWT in their respective unit. The results suggest that NPWT is effective for patients as proven by previous quantitative studies but it does increase the burden on healthcare providers, though the workers do not have grievances as they are willing to be flexible for the sake of the patients’ wellbeing. Moving forward, it is important to recognise the increasing skill load in healthcare nowadays, and increase awareness of moderating workload for healthcare workers.

Simulation Models for Analysis of Solid Bodies and Structures

In this honors thesis, simulation models for analyzing a variety of mechanical and structural problems were developed utilizing the Abaqus Finite Element software. The finite element method is a powerful method for solving complex problems, especially problems for which no closed-form solutions exist. The project had two main phases. In the first phase, the behavior of mechanical parts subjected to various applied loads such as bending moments, torsional loads, and temperature loads were investigated. The specific results consist of simulation models of the studied mechanical parts, along with the corresponding deformations and stress results. During the second phase, structural components such as trusses, portal trusses, and frames were analyzed. Included in the presentation are sample developed simulation models of the studied mechanical and structural parts, along with the corresponding deformations and stress results. The computed results obtained in the study are in complete agreement with the analytical values, clearly establishing that the developed models are suitable and accurate.

Computational Symmetric Grain Boundary Energy of Thorium Dioxide

With fossil fuels being depleted at a faster rate than ever, there has been an effort to convert fossil fuel energy to different forms of green energy. One of these forms is nuclear power, and while nuclear power itself is not new, new fuel sources for different types of reactors are being developed. This study aims to do computational experiments on Thorium Dioxide (a potential new nuclear fuel source) to look for the lowest grain boundary energy. Different orientations of the materials grain boundary will be put through the molecular dynamics program (LAMMPS) in search for the lowest energy and any trends from the different orientations.

Effect of Wingtip Devices on Transonic Aeroelastic Phenomenon of Fixed-wing Aircraft

Aeroelastic phenomena encountered during flight have considerable effects on the aerodynamic characteristics of fixed-wing aircraft. Transonic aeroelastic phenomena are often characterized by unique flow features which have complex ramifications for aircraft in transonic flight. Computational study of high-speed aeroelastic phenomena requires a fully-coupled aeroelastic algorithm. Therefore, wings with and without wingtip devices will be studied with a computational finite volume method solver accompanied by a finite element method solver for the calculation of structural deformation. The computational model for the flow field is validated with experimental data. Modeled flight conditions include transonic flows with bordering subsonic and supersonic cases included for completeness. The freestream Mach number and presence of wingtip devices will influence the aerodynamic characteristics of the wing, its elastic deformation, and the incurred structural stresses. The consequences of aeroelastic effects on the near-wing flow field are studied by visualization flow field surrounding the wing. The impact of dynamic aeroelastic effects on the flow over the wing surface and shock-induced flow separation is studied by consideration of the dynamic pressure on the wing surfaces.

Synthesis and Characterization of Fischer-Tropsch Catalysts for Sustainable Aviation Fuel Production

Our planet is experiencing a global climate crisis. Immediate actions must be taken in order to slow the increase of greenhouse gasses in our atmosphere. One area that has seen increased promise in emissions reductions is the aviation industry. Using sustainable aviation fuel (SAF) can have the effect of reducing the industries carbon footprint by over 70%, and goals have been set to achieve an aviation industry running on only SAF by the year 2050. While there are several ways to produce SAF, a novel solution is to use a Fischer-Tropsch reactor with a biochar derived syngas to produce energy dense fuels. Using biochar derived syngas for this process allows the final fuel products to be sourced from any assortment of biomass sources. This makes fuels produced from this process excellent forms of renewable energy. In order to make this process cost effective, it is ideal that the largest possible fraction of products lies within the C5-C20 hydrocarbon chain length category. This is the category of liquid hydrocarbons that SAF can be produced from. The best way to ensure a high selectivity to this range of liquid hydrocarbons is to utilize catalysts within the reactor. The purpose of this research is to synthesize and characterize promising catalysts in order to ascertain whether they will return a 70% yield of ideal liquid hydrocarbons.
