Study Of Selected Issues Of Solid-State Electrochemical Energy Storage, Yuchen Wang

Open Access Dissertations

The present dissertation focuses on three different topics of supercapacitor (SC) technology: 1) combination of galvanic cell components into SCs to mitigate the problem of self-discharge, 2) development of an all-solid-state SC/battery based on a superionic ceramic electrolyte and 3) mechanical-electrochemical study of a composite structural SC. A new hybrid supercapacitor SC with the galvanic cell materials is proposed to mitigate the self-discharge problem and to increase the storage-life. The galvanic cell components in the hybrid SC can provide a micro-current to compensate the self-discharge current. The hybrid SC was fabricated with active carbon electrodes, a polyvinylidene fluoride (PVDF)/lithium trifluoromethanesulfonate …

Improving The Social Behavior Of High School Students With Behavioral Challenges Through Self-Management Technology, Kathryn Dooley

Doctoral Dissertations

Students with Emotional and Behavioral Disorders (EBD) struggle with social behaviors (Bradley, Henderson, & Monfore, 2004) such as distractibility and impulsivity (Wagner et al., 2004). Self-management strategies have been used effectively to increase on-task behavior and decrease off-task or inappropriate behavior of students with EBD (Briesch & Chafouleas, 2009a). Additionally, self-management applications for the Apple iPad have led to improvements in the social behavior of students with challenging behavior (Bruhn, Vogelgesang, Fernando., & Lugo, 2016; Bruhn, Vogelgesang, Schabilion, Waller, & Fernando, 2015b; Vogelgesang, Bruhn, Coghill-Behrends, Kern, & Thoughton, 2016). However, a gap in the literature in the use of self-management …

Mechanistic Insights Into The Reaction Of Chlorination Of Tryptophan Catalyzed By Tryptophan 7-Halogenase., Tatyana Karabencheva-Christova, Juan Torras, Adrian J Mulholland, Alessio Lodola, Christo Christov

Michigan Tech Publications, Part 1

Tryptophan 7-halogenase catalyzes chlorination of free tryptophan to 7-chlorotryptophan, which is the first step in the antibiotic pyrrolnitrin biosynthesis. Many biologically and pharmaceutically active natural products contain chlorine and thus, an understanding of the mechanism of its introduction into organic molecules is important. Whilst enzyme-catalyzed chlorination is accomplished with ease, it remains a difficult task for the chemists. Therefore, utilizing enzymes in the synthesis of chlorinated organic compounds is important, and providing atomistic mechanistic insights about the reaction mechanism of tryptophan 7-halogenase is vital and timely. In this work, we examined a mechanism for the reaction of tryptophan chlorination, performed …

Unravelling The Correlation Of Electronic Structure And Carrier Dynamics In Cuins2 Nanoparticles, Wenhui Hu, John Ludwig, Brian Pattengale, Sizhuo Yang, Cunming Liu, Xiaobing Zuo, Xiaoyi Zhang, Jier Huang

Chemistry Faculty Research and Publications

In this work, we report the direct correlation of photoinduced carrier dynamics and electronic structure of CuInS₂ (CIS) nanoparticles (NPs) using the combination of multiple spectroscopic techniques including steady-state X-ray absorption spectroscopy (XAS), optical transient absorption (OTA), and X-ray transient (XTA) absorption spectroscopy. XAS results show that CIS NPs contain a large amount of surface Cu atoms with ≪four-coordination, which is more severe in CIS NPs with shorter nucleation times, indicating the presence of more Cu defect states in CIS NPs with smaller size particles. Using the combination of OTA and XTA spectroscopy, we show that electrons are trapped …

But to outline interactions between multiple particles towards equilibrium is still a challenge. Here, in our work, we look into …

Evaluation Of Cadmium Bioaccumulaiton Of Periphyton And Aquatic Invertebrates Within Tributaries Of The Buffalo National River, Jacob Rollins Mccauley

Student Theses and Dissertations

The Rush Mining District, located along the Buffalo River in Arkansas, has a significant history of metal-mining operations. The tails and spoils of these operations deposit heavy amounts of raw ore into streams, including the deposition of cadmium, a minor constituent. Periphyton and invertebrate samples from two creeks within the Rush Mining District were measured for cadmium. Additionally, two creeks with no history of mining were sampled. Periphyton samples from mining sites had significantly higher concentrations of cadmium than samples collected at control sites. Invertebrate samples were classified into trophic levels before analysis. Invertebrate samples collected at treatment sites only …

Genetic Structure And Diversity Of Southern Disjunct Populations Of Etheostoma Caeruleum And Chrosomus Erythrogaster, Kyle James Dineen

Student Theses and Dissertations

Etheostoma caeruleum and Chrosomus erythrogaster are widespread with overlapping distributions that show comparable patterns of naturally disjunct populations on their range margins. Both species have populations on Crowley’s Ridge, AR and the Bluff Hills, MS, relatively recent geological formations. Microsatellite DNA loci were examined for both fish species to evaluate genetic diversity and connectivity among populations on Crowley’s Ridge, the Bluff Hills, and larger core populations. Genetic structuring was found between all populations of both species with lower genetic diversity found in populations of both species on Crowley’s Ridge. Results from this study suggest that both target species colonized these …

Vertebrate Body Size Jumps The Wright Way, Peter J. Wagner

School of Biological Sciences: Faculty Publications

Fossil data provide copious evidence that anatomical (morphological) change within individual lineages is not constant: short bursts of great change commonly separate long durations of little change (1, 2). Despite this, most models of morphological change assume that probabilities of morphological character change are the same from one generation to the next: even if rates change over time—such as in “Cambrian explosion” or “early burst” models, where high disparity among anatomies evolves early—then it is still assumed that fast rates of continuous character change gave way to slow rates of continuous change (3). In statistical parlance, early bursts usually are …

Optimizing Fabrication And Modeling Of Quantum Dot Superlattice For Fets And Nonvolatile Memories, Pial Mirdha

Doctoral Dissertations

Quantum Dot Superlattice (QDSL) are novel structures which can be applied to transistors and memory devices to produce unique current voltage characteristics. QDSL are made of Silicon and Germanium with an inner intrinsic layer surrounded by their respective oxides and in the single digit nanometer range. When used in transistors they have shown to induce 3 to 4 states for Multi-Valued Logic (MVL). When applied to memory they have been demonstrated to retain 2 bits of charge which instantly double the memory density. For commercial application they must produce consistent and repeatable current voltage characteristics, the current QDSL structures consist …

An Experiment-Based Model Quantifying Antimicrobial Activity Of Silver Nanoparticles On Escherichia Coli, Mohammad A. Haque, Riku Imamura, George A. Brown, Venkata R. Krishnamurthi, Isabelle I. Niyonshuti, Tiffany Marcelle, Leanne E. Mathurin, Jingyi Chen, Yong Wang

Physics Faculty Publications and Presentations

Silver nanoparticles (AgNPs) are well known to exhibit antimicrobial effects through plausible interactions with proteins and/or deoxyribonucleic acid inside the bacteria. Yet a quantitative understanding on the antimicrobial activities of AgNPs remains obscure. Here we conducted in-depth kinetic growth assays and colony-forming unit (CFU) assays on Escherichia coli (E. coli) cultured in AgNPs or Ag ion-containing growth media. Compared to the Ag-absent culture medium, it was found that the growth rate of the bacteria remained unaffected but the lag time of the bacterial growth was extended due to the presence of AgNPs or Ag ions. From the CFU-based time-kill curves, …

Intestinal Exposure To Pcb 153 Induces Inflammation Via The Atm/Nemo Pathway, Matthew C. Phillips

Open Access Dissertations

Polychlorinated biphenyls (PCBs) are persistent organic pollutants that adversely affect human health. Although production of PCBs has stopped, they remain a pressing environmental problem due to their slow biodegradation and high lipophilicity. These properties enable PCBs to bio-accumulate in food chains leading to high levels of PCBs in the tissues of foodstuffs, especially fish. Despite dietary exposure being one of the main routes of exposure to PCBs, the gut has been widely ignored when studying the effects of PCBs. We set out to investigate the effects of PCB 153, the most environmentally prevalent PCB, on the gut, looking specifically for …

Synergistic Interactions Of H2 And N2 With Molten Gallium In The Presence Of Plasma, Maria L. Carreon, Daniel F. Jaramillo-Cabanzo, Indira Chaudhuri, Madhu Menon, Mahendra K. Sunkara

Physics and Astronomy Faculty Publications

The present study examines the interaction of hydrogen and nitrogen plasmas with gallium in an effort to gain insights into the mechanisms behind the synergetic effect of plasma and a catalytic metal. Absorption/desorption experiments were performed, accompanied by theoretical-computational calculations. Experiments were carried out in a plasma-enhanced, Ga-packed, batch reactor and entailed monitoring the change in pressure at different temperatures. The results indicated a rapid adsorption/dissolution of the gas into the molten metal when gallium was exposed to plasma, even at a low temperature of 100 °C. The experimental observations, when hydrogen was used, indicate that gallium acts as a …

We present our study on the spatially resolved Hα and M_* relation for 536 star-forming and 424 quiescent galaxies taken from the MaNGA survey. We show that the star formation rate surface density (Σ_SFR), derived based on the Hα emissions, is strongly correlated with the M_* surface density (Σ_*) on kiloparsec scales for star-forming galaxies and can be directly connected to the global star-forming sequence. This suggests that the global main sequence may be a consequence of a more fundamental relation on small scales. On the other hand, our result suggests that …

The Impact Of Reduced Arctic Sea Ice Extent On Cryospheric Snowfall, Alexander Carne

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Satellite observations show that sea ice extent in the Arctic has been declining from 1979 through present day, reaching record minimum extents in 2007 and 2012. Reduced sea ice extent allows for greater expanses of open water to interact with the Arctic atmosphere, potentially leading to changes in the Arctic climate. The greatest declines in Arctic sea ice extent have occurred in summer and autumn. During these seasons, it is likely that the decrease in Arctic sea ice extent led to an increase in atmospheric sensible and latent heat fluxes, possibly leading to increases in Arctic temperature and moisture. Increases …

Homogenization Techniques For Population Dynamics In Strongly Heterogeneous Landscapes, Brian P. Yurk, Christina A. Cobbold

Faculty Publications

An important problem in spatial ecology is to understand how population-scale patterns emerge from individual-level birth, death, and movement processes. These processes, which depend on local landscape characteristics, vary spatially and may exhibit sharp transitions through behavioural responses to habitat edges, leading to discontinuous population densities. Such systems can be modelled using reaction–diffusion equations with interface conditions that capture local behaviour at patch boundaries. In this work we develop a novel homogenization technique to approximate the large-scale dynamics of the system. We illustrate our approach, which also generalizes to multiple species, with an example of logistic growth within a periodic …
