Characterization Of Carbon Nanotube/Polystyrene Composites Prepared Via Microwave-Induced Polymerization, Hubert Agamasu

College of Graduate Studies: Theses & Dissertations

Carbon nanotubes (CNTs), with their excellent mechanical properties, are well suited to the production of composites with good strength-to-weight ratio. However, the use of nanotubes as reinforcement is hampered by the lack of interaction between their inert surfaces and matrices. This, coupled with the van der Waal’s interactions between individual nanotubes, leads to agglomeration of CNTs in media. Functionalization is an efficient means to disperse nanotubes as well as increase their reactivity. The irradiation of CNTs with microwaves generates instantaneous, localized heating, being used in this work to trigger the rapid, thermal, free radical polymerization of styrene. Under microwaves, olefin-functionalized …

Their Country: Black Women, Three Chords, And The Truth, Dmetri J. Smith

College of Graduate Studies: Theses & Dissertations

ABSTRACT

Country music has long overlooked and at times outright erased the contributions of people of African descent. The past and present contributions of Black women are particularly ignored. Country music— a racially contested space centered in Nashville, Tennessee— is imbued with themes referencing the “good ole days” that were dangerous times for anyone who was not White, male, cisgender, and heterosexual. The genre has only become slightly more welcoming to those who are not part of the dominant class. And yet, there are Black women who feel called to use country music as their storytelling medium. My research shows …

Investigating Division Quest: A Text-Based Adventure Narrative Game For Overcoming Difficulties Of Mitosis Learning, Amanda G. Conner

College of Graduate Studies: Theses & Dissertations

Mitosis learning is a source of struggle for many introductory biology students. Much of this difficulty stems from an overwhelming amount of terminology and moving pieces as well as the abstract nature of cellular processes. Game-based learning (GBL) has been used in other contexts to reduce cognitive load and provide relatable experiences upon which students can construct their mental models. However, commercial GBL is often expensive and difficult to align with individual instructor teaching preferences and learning objectives. In this study, we use a mixed methods approach to explore the use of a GBL tool made in Twine to overcome …

Beyond The Strong Black Woman: Navigating Resilience And Mental Health Using Social Media For Culturally Tailored Resources, Muchaneta N.M. Chikawa

College of Graduate Studies: Theses & Dissertations

Society views the strength of Black women as commendable as it shows positive qualities such as resilience and perseverance. While these traits are characterized as positive, Black women’s survival in American society has heavily depended on their strength, resulting in mental health illnesses such as anxiety and depression. The idea that Black women must exude strength and fortitude through adversity is labeled the Strong Black Woman Schema (SBWS). The SBWS is a race-gender schema that prescribes culturally-specific feminine expectations for Black women.

There are limited culturally-tailored resources for Black women to address mental health at collegiate institutions. As a result …

“Why Blackness, Black Girl?:” Discovering Multilocal Blackness In Wonderful Adventures Of Mrs. Seacole In Many Lands And Americanah, Sydney A. Ware

College of Graduate Studies: Theses & Dissertations

In “Why Blackness, Black Girl?” I argue that as a consequence of imperialism, Western Blackness has an interdependent relationship with whiteness, resulting in the domination of Western Blackness over non-Western Blackness. Tensions between both groups are usually portrayed by Western media as divisive. I pose Multilocality as a theory to reconcile this tension. I use Taiye Selasi's concept of the multilocal, and her Three Markers (3 R’s) to identify where hybridized identities are local to and how they can connect to each local space. I expand Selasi’s concept into a theory called Multilocality, and added a fourth marker that I …

Investigation Of Topologically Protected Wave Propagation Near Dirac-Like Cones In Acoustic Metamaterials, Md Arif Iqbal Khan

College of Graduate Studies: Theses & Dissertations

This study presents a novel approach to investigate an exceptionally rare acoustic phenomenon – topologically protected wave propagation (TPWP) within a solid-solid domain. While previous research has attempted to unravel the physics behind this phenomenon, most efforts have been grounded in the framework of condensed matter physics and quantum mechanics often requiring complex geometries to realize TPWP in solid-fluid interactions. In contrast, this thesis introduces a geometric tuning method that enables the achievement of TPWP with simpler geometric configurations within a solid-solid domain. Rather than explaining by the quantum trio - quantum anomalous hall effect, quantum valley hall effect, and …

Hoodies In The Halls Of Power: A Rhetorical Materialist Critique Of Professional Decorum In The United States Senate, Ryan Cheek, Samuel T. Allen

English and Technical Communication Faculty Research & Creative Works

This brief paper explores the controversy surrounding Senator John Fetterman's sartorial choices of casual attire in the hyper-professionalized space of the United States Senate. Fetterman's clothing choices transcend mere fashion; they embody a statement of class identity and challenge the established power dynamics within the Senate. His attire reflects Pittsburgh's industrial and labor-oriented history, in contrast to the conventional, affluent image most associated with politicians. Although controversial, Fetterman's white male privilege minimized the consequences of his indecorous behavior. The reactions to Fetterman's attire highlight the debate over what constitutes appropriate professional decorum, unveiling the underlying biases and demonstrating how something …

Angle-Dependent Photoinduced Changes Of Near-Infrared Transmission In Amorphous Selenium Films, Kaitlin Hellier, Emily Enlow, Seyedehnajmeh Montazeri, Mina Esmaeelpour, Shiva Abbaszadeh

Electrical and Computer Engineering Faculty Research & Creative Works

Amorphous selenium (a-Se) is a promising semiconductor for a variety of photoconductive applications, predominantly in X-ray detection. In addition, material properties introduce several other potential applications in nonlinear optics. Photodarkening (PD) presents an interesting area of study; when exposed to band-region light, metastable structural changes induce a shift in the band edge and increase tail absorption. In this work, we investigate these effects utilizing a near-infrared (NIR) probe to avoid generating any darkening during beam transmission. We observe an unexpected result; here, we present the effects of band region exposure in NIR transmission (1570 nm). We observe a shift from …

Highly Sensitive Liquid-Level Sensing Based On Microwave Frequency Domain Reflectometry And Interferometry, Chen Zhu, Osamah Alsalman, Jie Huang

Electrical and Computer Engineering Faculty Research & Creative Works

Frequency domain reflectometry (FDR) and interferometry are two widely used investigative techniques that have been instrumented using optical and microwave devices for a diverse array of sensing applications. In this paper, we present a highly sensitive liquid-level sensor using a custom hollow coaxial cable transmission line. Measurements of liquid levels with high sensitivity and resolution can be achieved by both FDR and interferometry-based measurements using the same sensor device. We show that FDR-based measurements are more straightforward for liquid-level sensing and are suitable for both small and large variations of liquid level, while interferometry-based measurements provide slightly higher measurement resolution …
