Stem And Pdf Simulation Of Crystalline And Amorphous Materials, Yang Yang, Francisco Lagunas Vargas

Mechanical Engineering and Materials Science Independent Study

The aberration corrected scanning transmission electron microscope (STEM) is a powerful tool for nanoscale characterization, as it is capable of imaging structures with sub-angstrom resolution. An optical microscope uses visible light to magnify objects, which is limited to ~1000X due to the limited resolving power of light. Here, we applied STEM simulations via PRISMATIC and PY4DSTEM, in order to compute images of crystals, 2D materials, and metallic glasses. Practically, computational simulations are important due to the operating cost of STEM and time required to be trained on the equipment. More importantly, simulations provide a direct comparison between theory and experimental …

Fabrication Process For Thin Film Solution Based Indium Galium Zinc Oxide (Igzo), Jeremy Choh

Mechanical Engineering and Materials Science Independent Study

Oxide thin film transistors (TFTs) have gained popularity as a replacement silicon based TFTs, with indium gallium zinc oxide (IGZO) being the leading candidate. A solution-based fabrication method has been studied to replace the current fabrication method using radio frequency or direct current sputtering. However, the solution based fabrication method has shown to have low reliability in producing high quality IGZO films. Thus, the fabrication parameters to produce high quality IGZO films were studied. It was found that an IGZO solution with a 0.5M concentration of 2-methoxyethanol annealed at 300°C for 30 minutes with a prebake at 70°C for 10 …

First-Principles And Deep Learning Frameworks To Predict The Electronic, Magnetic And Electrical Properties Of V-Doped Sic Nanotube, Debarati Dey Roy, Sevda Rzayeva, Sevinj Guluzade, Vusala Nabi Jafarova

Turkish Journal of Physics

Nowadays, with the miniaturization of nanoindustry, we are increasingly interested in doping effects for nanotube systems. In this study, based on density functional theory (DFT) and local spin density approximation (LDA) methods within Hubbard U corrections, the electronic, magnetic and electrical properties of single-wall silicon carbide nanotubes doped with vanadium were theoretically studied. Although the undoped SiC system is nonmagnetic, the V-doped SiC nanotube induces magnetism and the total magnetic moment of this magnetic material is equal to ~1 µB. Density of states calculations indicated that the magnetization of SiC:V single-wall nanotubes mainly comes from the 2p orbitals of carbon …

Exposures, Protections, And Barriers: Advancing Understanding Of Agricultural Worker Health, Alexandra A. Farfalla

Theses & Dissertations

Farming is a hazardous occupation. Exposures are multifactorial, variable, and shaped by overlapping tasks, environments, and social contexts. This dissertation aimed to illustrate the complexity of agricultural exposures and the barriers to protective practices through three complementary studies.

The first study examined co-exposures to solvents and noise as risk factors for hearing loss (HL) among 7,495 farmers and ranchers in a 7-state region. Results indicated nearly 60% of co-exposed participants reported hearing loss, with an adjusted odds ratio nearly six-fold (OR=6.03, [4.67-7.78]) for moderate/severe HL. This work highlights the importance of recognizing chemical exposures as a modality in HL in …

Biology Theses, Dissertations, and Student Creative Activity

The quality and availability of valuable backwater habitats have declined in many rivers, including the Upper Mississippi River (UMR), due to river modifications and land use change. Habitat Rehabilitation and Enhancement Projects (HREPs) are implemented by the Upper Mississippi River Restoration Program and often aim to mitigate accelerated sedimentation and degradation of backwater habitats. One HREP in Pool 12 of the UMR targeted overwintering fish habitat by restoring four backwaters within 14 RKM. Fish community data was collected before (2006-2012) and after (2020-2024) restoration in Pool 12 and a downstream, control reach, Pool 13. The first objective of my study …

Self-Assembling Rna Nanostructures Are Highly Sensitive To Environmental Conditions, Jordan Aposhian, Surya Pratap S. Deopa, Scott Horowitz, Joseph D. Yesselman

Chemistry and Biochemistry: Faculty Scholarship

Recent developments in RNA nanotechnology have led to an increase in the design of specific, higher-order RNA structures, which will ultimately be used in drug delivery and immunomodulation applications. As researchers create RNA nanostructures with the intention of making them a standard tool in molecular biologists' toolkits, further investigation is required into the robustness of RNA designs. Primarily, in what different molecular contexts are the designed and intended nanostructures stable? In this work, we show that RNA nanostructure self-assembly is highly sensitive to environmental conditions by using second-order right-angle light scattering. While a test RNA hexagonal grid nanostructure forms correctly …

A Fish & A Bird, Deanna Moorehead

Theses

As a curtain of trees opens and dawn breaks over the glistening waters of Lake Ontario, a fish and a bird spot each other through the surface and fall madly in love. They dance and sing together from their respective atmospheres, yet each time the bird soars past the water's edge and onto the beach, the fish cannot follow. Night after night, by the light of the moon, the fish trains herself to leap out of the water, hoping to breach high enough to join her beau above. Late one afternoon, the fish approaches the shore, where the bird stands …

Scout 07, Austin Roberts

Theses

Throughout my tenure at RIT, I have produced multiple short films, undertaken gaming co-ops, and pursued an independent study centered on gaming assets to expand my technical and creative skills. For my thesis film, I sought to merge these experiences by concentrating on environmental storytelling—a deliberate challenge, given faculty concerns that narratives lacking strong character focus may struggle to engage audiences emotionally. With these considerations in mind, I crafted a film featuring a secondary character within a rich environment, designed to immerse viewers and provoke curiosity about the story’s temporal and spatial context.

Assessment Of Polymeric Chloroquine Formulations For Targeted Therapy Of Ulcerative Colitis And Metastatic Colorectal Cancer, Neha Kumari

Theses & Dissertations

Effective targeted drug delivery is a critical unmet need in the management of both ulcerative colitis and metastatic colorectal cancer, where conventional systemic therapies may be hindered by suboptimal efficacy and significant side effects. This thesis explores the development and preclinical assessment of polymeric chloroquine (PCQ)-based nanotherapeutics, leveraging stimuli-responsive designs for disease-specific delivery and action.

For ulcerative colitis, a reactive oxygen species (ROS)-responsive nanogel system was engineered to release PCQ, a macromolecular derivative of hydroxychloroquine, specifically in the inflamed areas within the colon. Nanogels with well-defined size and positive surface charge were synthesized via reversible fragmentation chain transfer (RAFT) polymerization …

Development And Characterization Of Non-Viral Delivery Systems For Pulmonary Delivery Of Nucleic Acid Therapeutics, Kasturi Siddhanta

Theses & Dissertations

The development of non-viral delivery systems for pulmonary delivery of nucleic acid therapeutics is driven by the need for safer and more accessible approaches to treat lung diseases, while avoiding the systemic side effects and immune responses associated with viral vectors. Such systems encompass both non-invasive inhalation-based platforms, and systemically administered platforms designed to achieve localized lung delivery. These strategies aim to enable high drug concentrations at the site of action, rapid onset of therapeutic effect, and greater therapeutic efficacy than existing treatments. Designing effective pulmonary delivery systems requires precise optimization of particle properties—including size, morphology, surface characteristics, cell-specific targeting, …

Role Of Nadph Oxidase 4 In Murine Cancer-Associated Fibroblast, Faith M. Gomez

Theses & Dissertations

Breast cancer is the second leading cause of cancer deaths in women in the United States. Frontline hormone therapies for breast cancer prove ineffective in triple negative breast cancer tumors wherein the hormones estrogen, progesterone, and HER2 are downregulated or absent; therefore, patients diagnosed with triple negative breast cancer are primarily limited to chemotherapies which carry a higher failure and resistance rate. Here we target cancer associated fibroblasts as potential drivers of chemoresistance in triple negative breast cancer. We investigated the mechanism by which Nox4 regulates the YAP/TAZ pathway in modulating DTX sensitivity and sought to determine if targeting Nox4 …

Macroinvertebrate Community Dynamics In A Recovering, Hypersaline Estuary, Catherine M. Eckert, Claudia A. Tamez, Erin E. Easton, David Hicks

School of Earth, Environmental, & Marine Sciences Faculty Publications

The Bahia Grande is a 6,500—acre tidal basin located at the southernmost tip of Texas. Tidal flow into this coastal estuary was cut off in the 1930s, causing the basin to dry up for ~70 y. A pilot channel connecting the Bahia Grande to tidal waters was constructed in 2005, allowing flooding of the basin to occur. Throughout the period reported herein (2005–2019), the system remained characterized by persistent spatial and temporal episodes of extreme hypersalinity (>70)—a critical factor influencing estuarine community composition and driving key ecological processes. With additional rehabilitation actions forthcoming, characterization of the estuary is essential …

Playing By Feel: Gender, Emotion, And Social Norms In Overwatch Role Choice, Cristo Leon, Angela Arroyo, James Lipuma

STEM for Success Resources

This paper explores how emotion, gameplay context, and social norms shape role choice in both digital and institutional systems. Using Overwatch as a case study, it examines gendered experiences of physiological excitement and decision-making during play. Women often describe heightened emotional engagement where victory represents both personal achievement and resistance to cultural expectations. Such emotions influence situational choices, including whether to play as a Tank, DPS, or Support, and which hero to select based on perceived risk or visibility. Drawing on feminist game studies and transdisciplinary communication, the authors argue that role preference is determined not only by game mechanics …

Exploring The Medicinal Properties Of Indigenous Plants Within An Enabling Program: Bridging The Gap Between School, Aboriginal And Torres Strait Islander Knowledge And Science, Sharon L. Gough, Julie Sartori, Angela Jones

Research outputs 2022 to 2026

In 2021, less than half of Australian universities considered Indigenous perspectives in curriculum development, with only 15% ensuring Indigenous content in all courses. Literature acknowledges that a strengths-based approach to the inclusion of Aboriginal and Torres Strait Islander knowledge and perspectives, enhances representation and decolonises curriculum. In 2020, Noongar elder Vivienne Hansen, and John Horsfall created Noongar Bush Medicine, detailing the medicinal use of Indigenous plants. Yeshi, Turpin, Jamtsho, and Wangchuk noted that many Aboriginal and Torres Strait Islander communities use native plants for health purposes. However, there is limited data on the therapeutic efficacy of these plants. In 2024, …

Evaluation And Calibration Of Coupled Low-Cost Particulate Matter Sensors, Tyler Cargill

McKelvey School of Engineering Graduate Student Theses & Dissertations

Low-cost sensors (LCS), if used appropriately, are useful instruments to elucidate human exposure to particles suspended in the air (i.e. particulate matter, PM). Characterizing this exposure is crucial, as exposure to PM2.5 (i.e. particles with aerodynamic diameter ≤ 2.5 μm) negatively affects the respiratory, cardiovascular, and other organ systems and is the leading environmental burden for global mortality. Similarly, exposure to particles with aerodynamic diameters greater than 2.5 μm and less than or equal to 10 μm, here forth termed as PMCoarse, is known to cause health ailments for the upper respiratory system. This dissertation focuses on the MODULAIRTM-PM (MOD-PM), …

Investigating Metabolic Heterogeneity In Engineered Isogenic Microorganisms, Xinyue Mu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Engineered microorganisms play an increasingly important role in the sustainable production of fuels, bioplastics, and other valuable biomaterials. Successful industrial deployment depends on maximizing product titers and ensuring process robustness at large scale. However, one of the major obstacles is non-genetic cell-to-cell heterogeneity arising from stochastic intracellular processes. Such heterogeneity can result in subpopulations that divert substrates toward growth rather than product biosynthesis, ultimately reducing yield and contributing to batch-to-batch inconsistency. To better understand the mechanisms by which cell-to-cell variation emerges, propagates, and impacts bioproduction, this dissertation investigated how intracellular energetic dynamics and stochastic biosynthetic noise contributed to metabolic heterogeneity …

Late-Stage Capitalism And Consumerism In Higher Education: A Morphogenetic Analysis, Kallen Zhou

Publications

Facing widespread student disengagement and dissatisfaction, U.S. higher education is undergoing a paradigm shift, detaching from its civic and pedagogical origins. A key force driving this transformation is the rise of student consumerism. While existing literature documents market-driven actions adopted by higher education institutions (HEIs) and the consumer roles students play, it overlooks structural market forces. Specifically, little theorization exists on the relationship between late-stage capitalism and student consumerism. This paper addresses that gap through two steps: first, offering a historical analysis of the traditional university model, late-stage capitalism, academic capitalism, and the decline of the liberal arts; second, developing …

Creating A Radical Social Change Campaign To Restore Rational Thinking: A Theoretical Framework, John S. Long

Student Theses and Dissertations

Rational thinking is a skill and mindset that is under siege in modern society, becoming increasingly endangered as we devolve into increasingly hyper-partisan communities rife with echo chambers and confirmation biases. The most basic processes of analyzing issues and facts to develop clearly thought-out and defendable positions have been abandoned in favor of a zealous devotion to toe the party line, no matter the evidence or implications. What we are witnessing firsthand is the fast-approaching culmination of the post-truth era.

One might assume that an issue with such far-reaching implications across our entire society would generate a significant amount of …

The Bmt: Will This Time Be Different?: Red Hook Braces For A Mega-Project On The Waterfront. Can It Avoid The Mistakes Of Atlantic Yards?, Steve Kastenbaum

Capstones

"The BMT: Will this time be different?" investigates how New York City's push to rapidly build housing is reshaping communities. A $3.5 billion mega-project at the Brooklyn Marine Terminal promises transformation through 6,000 apartments, a modernized port, and waterfront improvements, but residents are split on whether it represents progress or displacement. The development uses a controversial "general project plan" process that bypasses normal community review, the same approach that enabled the still-unfinished Atlantic Yards project. Local voices in Red Hook range from excitement about investment, jobs and amenities to fears about gentrification and broken promises. This pilot episode launches a …
