Physical Modeling Of Filament Growth And Resistive Switching In Metal Oxide-Based Rram, Kena Zhang Dec 2022

Physical Modeling Of Filament Growth And Resistive Switching In Metal Oxide-Based Rram, Kena Zhang

Material Science and Engineering Dissertations - Archive

Metal oxide-based resistive random-access memories (RRAM) exhibit several excellent performances, such as nanosecond switching speed, large write-erase endurance, and long retention time, and can potentially replace the traditional circuit elements for use as the fundamental units in next-generation hardware deep-learning or neuromorphic systems. The functionality of a metal oxide-based RRAM is attributed to an oxygen vacancy (V_O^(..))-rich conductive filament (CF), which initially forms, and later dissolves or regrows inside the oxide layer during the resistive switching process. However, the complicated interplays among the coexisting chemical, electrical, mechanical, and thermal effects during the formation, growth, and rupture of the CFs make …

Effects Of Graphene In High-Density Polyethylene Microfibers, Ashish Lal Sivadas Anilal

Material Science and Engineering Theses - Archive

High-Density Polyethylene uniquely can induce banded spherulites as it is crystallized from its melt. We studied the effects of graphene in the crystallography of banded HDPE by examining parameters such as the extent of twisting, spherulitic growth, and nucleation density. The application of graphene as a multifunctional filler in polymer matrices is a great topic of interest because graphene at low concentrations can bring many improvements in mechanical, electrical, and thermal properties. We synthesized graphene oxide by chemical oxidation of graphite and further studied its effects in the twisted crystallography of HDPE. Three batches of fibers were extruded: two batches …

Sub-10k Cold-Electron Injection To Silicon At Room Temperature, Ojas Tushar Bhayde Dec 2022

Sub-10k Cold-Electron Injection To Silicon At Room Temperature, Ojas Tushar Bhayde

Material Science and Engineering Theses - Archive

The Fermi-Dirac thermal excitation of electrons results in unwanted off-state leakage currents in metal-oxide-semiconductor field-effect transistors (MOSFETs), leading to excessive power consumption in modern electronic devices. The electron thermal excitation results in a theoretical subthreshold slope limit of 60 mV/decade at room temperature, which forces the devices to use a high supply voltage leading to high power consumption. This study investigates a new architecture capable of suppressing electron thermal excitation by using a quantum well (QW) as an energy filter. The QW energy filter is composed of a tunneling barrier 1 (0.5 to 1 nm Al2O3 or 0.3-1 nm Si3N4 …

Creative Collaboration In Rural Texas Communities, Kathryn May Lattimore Norris

Public Affairs Dissertations - Archive

The body of research investigating collaboration has grown exponentially in recent years with the realization of its potential in generating innovative solutions to complex problems. Even though an abundance of literature on collaboration exists, scholars have fallen short of understanding how collaboration works towards creativity. Lack of consensus on understanding how this critical construct functions has not only made furthering theory on the matter challenging for researchers, but also made recognizing, utilizing, and realizing the full benefit of collaboration difficult for practitioners. Until the ways collaboration can result in creative outcomes are better understood, practitioners will not be able to …

Bioactivation And Detoxification Of Organophosphorus Pesticides In Freshwater Planarians Shares Similarities With Humans, Danielle Ireland, Christina Rabeler, Taixi Gong , '24, Eva-Maria S. Collins Dec 2022

Bioactivation And Detoxification Of Organophosphorus Pesticides In Freshwater Planarians Shares Similarities With Humans, Danielle Ireland, Christina Rabeler, Taixi Gong , '24, Eva-Maria S. Collins

Biology Faculty Works

Organophosphorus pesticides (OPs) are a chemically diverse class of insecticides that inhibit acetylcholinesterase (AChE). Many OPs require bioactivation to their active oxon form via cytochrome P450 to effectively inhibit AChE. OP toxicity can be mitigated by detoxification reactions performed by carboxylesterase and paraoxonase. The relative extent of bioactivation to detoxification varies among individuals and between species, leading to differential susceptibility to OP toxicity. Because of these species differences, it is imperative to characterize OP metabolism in model systems used to assess OP toxicity. We have shown that the asexual freshwater planarian Dugesia japonica is a suitable model to assess OP …

An In Vitro 3d Model To Investigate Iol: Posterior Lens Capsule Interactions On Lens Epithelial Cell Responses, Joyita Roy Dec 2022

An In Vitro 3d Model To Investigate Iol: Posterior Lens Capsule Interactions On Lens Epithelial Cell Responses, Joyita Roy

Bioengineering Dissertations - Archive

ABSTRACT: Posterior Capsule Opacification (PCO) is the most common complication associated with Intraocular Lens (IOL) implantation. The disease is caused by the infiltration and proliferation of Lens Epithelial Cells (LEC) into the interface between the IOL and Posterior Lens Capsule (PLC). The severity of these cell responses depends on a lot of factors like the IOL design, IOL material, and interaction between the IOL and the posterior lens capsule. While some studies have also shown that adsorption of certain proteins present in the PLC, like fibronectin, may affect IOL-induced PCO in the clinical setting, the mechanism governing such interactions is …

Spare The Rod: African American Students’ Experience Of Postsecondary Student Conduct Processes, Melissa Sanders Dec 2022

Spare The Rod: African American Students’ Experience Of Postsecondary Student Conduct Processes, Melissa Sanders

Educational Leadership & Policy Studies Dissertations - Archive

Although African Americans enroll at postsecondary institutions at similar rates as other ethnic groups, consistently, they lag in degree completion. This has led to lower wages, fewer employment opportunities, and higher health disparities among African Americans. Consequently, the literature is full of studies attempting to increase Black student degree attainment. This includes their perception of campus climates, academic preparedness, and sense of belonging. However, other opportunities to promote and encourage African American scholastic success, such as the disciplinary process, are understudied. To address this gap, I utilized a phenomenological qualitative study to examine the way African Americans perceived the impact …

Targeted Drug-Loaded Nanoparticle System (Tdnps) To Ameliorate And Treat Idiopathic Lung Fibrosis, Harish Ramachandramoorthy Dec 2022

Targeted Drug-Loaded Nanoparticle System (Tdnps) To Ameliorate And Treat Idiopathic Lung Fibrosis, Harish Ramachandramoorthy

Bioengineering Dissertations - Archive

Idiopathic pulmonary fibrosis (IPF) is a fatal progressive disease with a dismal prognosis and 3-5 years of survival. Up to date, there are no effective treatments, and a few current therapies that do not ameliorate the pulmonary fibrosis but rather just increase the survival time by 2-3 years. The major factor limiting the treatment is the lack of targeted therapies to deliver the drugs past the mucosa, into the disease microenvironment. To combat this disease, we proposed a localized therapy via our targeted drug-loaded nanoparticles (TDNPs) to effectively deliver drugs and treat lung fibrosis. Our objective was to design TDNPs …

Performance Evaluation Of The Modified Moisture Barrier In Stabilizing Shallow Slope Failures, Muhasina Manjur Dola Dec 2022

Performance Evaluation Of The Modified Moisture Barrier In Stabilizing Shallow Slope Failures, Muhasina Manjur Dola

Civil Engineering Dissertations - Archive

Each year significant number of highway slope failures are reported in the United States, especially in states like Texas where expansive clayey soil is prevalent. Slopes constructed over expansive clay often experience recurring shallow failures following their construction which poses maintenance problems to the Texas Department of Transportation (TxDOT). These shallow slope failures can be primarily attributed to the considerable volume change that expansive clay soil undergoes from seasonal climatic variation. Furthermore, under unsaturated conditions during dry periods, high matric suction (i.e., negative porewater pressure) exists in soil slopes. The existence of matric suction contributes to the shear strength of …

Factors Affecting Health-Seeking Behaviour Among Men Who Have Sex With Men In Starehe Sub-County, Nairobi City County, Anthony Omariba

MSc in Advanced Practice Nursing

Men who have sex with other men (MSM) exist in Africa, as they do elsewhere. The continued proscription of MSM behavior leads to exclusion and discrimination. According to a global report, MSMs are responsible for most HIV transmission. MSMs in Kenya constantly fear being hurt because of their sexual orientation, and there is scant knowledge of their health-seeking behavior. There is a need to improve the health of this group to lower disease spread to achieve global HIV reduction. This study aims to explore MSM healthcare-seeking behavior, describe barriers to healthcare-seeking, and establish perceptions of the sexual risks associated with …

Ocean acidification (OA) has resulted in global-scale changes in ocean chemistry, which can disturb marine organisms and ecosystems. Despite its extensively populated coastline, many marine-dependent communities, and valuable economies, the Gulf of Mexico (GOM) remains a relatively understudied region with respect to acidification. In general, the warm waters of the GOM are better buffered from acidification compared to higher latitude seas, yet long-term acidification has been documented in several GOM regions. OA within the GOM is recognized as spatially variable, particularly within the coastal zone where numerous physical and biogeochemical processes contribute to carbonate chemistry dynamics. The historical progression of …

Applied Studies Of Raptor Sensory Ecology Are Rare, Christopher J.W. Mcclure, Simon Potier, Jesse R. Barber

Biology Faculty Publications and Presentations

Light and noise often act as pollutants, but can also be used as tools for managing wildlife (e.g., sensory deterrents). Given that raptors are among the most threatened groups of birds, we expected there to be a moderate amount of applied research on their sensory ecology. We searched Web of Science and Google Scholar to quantify and classify the research that has been conducted on the applied sensory ecology of raptors. Of 32 studies assessing the effects of sensory pollution on raptors, we found that 10 studies examined effects of light pollution and 24 studies examined effects of noise pollution. …

Drone Imagery Protocols To Map Vegetation Are Transferable Between Dryland Sites Across An Elevational Gradient, Anna Roser, Josh Enterkine, Juan M. Requena-Mullor, Nancy F. Glenn, Alex R. Boehm, Marie-Anne De Graaff, Patrick E. Clark, Fred Pierson, T. Trevor Caughlin

Biology Faculty Publications and Presentations

The structure and composition of plant communities in drylands are highly variable across scales, from microsites to landscapes. Fine spatial resolution field surveys of dryland plants are essential to unravel the impact of climate change; however, traditional field data collection is challenging considering sampling efforts and costs. Unoccupied aerial systems (UAS) can alleviate this challenge by providing standardized measurements of plant community attributes with high resolution. However, given widespread heterogeneity in plant communities in drylands, and especially across environmental gradients, the transferability of UAS imagery protocols is unclear. Plant functional types (PFTs) are a classification scheme that aggregates the diversity …
