The Use Of Polystyrene-Tethered Fullerenes As Stabilizers In Bulk Heterojunctions, Joshua A. Moore

Theses and Dissertations

Self-assembly of nanoparticles can potentially provide improvements for many current applications and could influence the design of future technologies. The assembly of nanoparticles, which can be controlled through external forces or through molecular interactions, can affect the properties of a material. Nanoparticles can be chemically modified by attaching molecules such as polymers to their surface. The nature and placement of these tethers affects the arrangement of the nanoparticles leading to materials with novel chemical, electrical, and physical properties. In this research, the assembly of the fullerene (C60) based nanoparticles was modified using polystyrene-tethered fullerenes (PTFs) as additives. Polystyrene (PS) was …

Solution Processed Cu(In,Ga)S2 Thin Film And Nanowire Photovoltaics, Johnthan Armstrong

Theses and Dissertations

Solar energy conversion is a highly attractive process for clean and renewable power for the future. Cu(In,Ga)(Se,S)2/CdS/ZnO has proven itself to be a worthwhile photovoltaic combination achieving record efficiencies upwards of 20%. These record efficiencies have been obtained through vacuum-based approaches. However, the high cost of vacuum-based fabrication processes become a barrier to affordable solar cells as an energy source. As a result, solution-based approaches have become the focus of many studies which have achieved record efficiencies of 15%. These solution-based approaches have not matched up with the vacuum-based approaches. In this work, we investigate methods to improve the solution-based …

Biological Processing Rhythms In Beginning Readers: A Spectrographic Examination Of Oral Reading Behavior On Texts Of Increasing Difficulty, Laura Juhl

Theses and Dissertations

A qualitative comparative research design grounded in the theory of biological processing rhythms (Holdaway, 1979, Miner, 1903) described oral reading behaviors in different levels of beginning early readers during oral reading of texts of increasing difficulty. Spectrographic analysis with waveform data triangulated with running record data, Slosson Oral Reading Tests (SORT-R3) (Slosson & Nicholson, 1990) and transcriptions allowed an in-depth analysis into the behaviors. Three research questions guided the analysis: (1) How do biological processing rhythms operate with different levels of beginning readers? (2) How do biological processing rhythms, as examined through waveforms of oral reading behavior, operate as beginning …

Electrophoretic Deposition Of Gallium With High Deposition Rate, Hanfei Zhang, Yiping Mao, Sunand Santhanagopalan, Dennis Desheng Meng

Michigan Tech Publications, Part 1

In this work, electrophoretic deposition (EPD) is reported to form gallium thin film with high deposition rate and low cost while avoiding the highly toxic chemicals typically used in electroplating. A maximum deposition rate of ~0.6 μm/min, almost one order of magnitude higher than the typical value reported for electroplating, is obtained when employing a set of proper deposition parameters. The thickness of the film is shown to increase with deposition time when sequential deposition is employed. The concentration of Mg(NO₃)₂, the charging salt, is also found to be a critical factor to control the deposition …

Myoelectric Prostheses: Novel Methodologies For Enhancing Usability And Control, Ghulam Rasool

Theses and Dissertations

Control of powered prostheses using the information from leftover muscles in amputees is a challenging problem. I investigated the problem with a view to find clinically reliable and robust schemes that can interpret human intent and control a powered prosthesis in real-time. Recently, pattern classification systems have been suggested to map muscle activation patterns to the human intent (or the movement). However, due to the underlying generic structure, system-specific information cannot be exclusively incorporated into pattern classification algorithms. I have proposed two new methodologies in my research. The first one extended the pattern classification with a new feature set comprised …

Interfacial Polymerization For Colorimetric Labeling Of Protein Expression In Cells, Jacob L. Lilly, Phillip R. Sheldon, Liv J. Hoversten, Gabriela Romero, Vivek Balasubramaniam, Brad J. Berron

Chemical and Materials Engineering Faculty Publications

Determining the location of rare proteins in cells typically requires the use of on-sample amplification. Antibody based recognition and enzymatic amplification is used to produce large amounts of visible label at the site of protein expression, but these techniques suffer from the presence of nonspecific reactivity in the biological sample and from poor spatial control over the label. Polymerization based amplification is a recently developed alternative means of creating an on-sample amplification for fluorescence applications, while not suffering from endogenous labels or loss of signal localization. This manuscript builds upon polymerization based amplification by developing a stable, archivable, and colorimetric …

Ontogenetic Scaling Patterns And Functional Anatomy Of The Pelvic Limb Musculature In Emus (Dromaius Novaehollandiae), Luis P. Lamas, Russell P. Main, John R. Hutchinson

Department of Basic Medical Sciences Faculty Publications

Emus (Dromaius novaehollandiae) are exclusively terrestrial, bipedal and cursorial ratites with some similar biomechanical characteristics to humans. Their growth rates are impressive, as their body mass increases eighty-fold from hatching to adulthood whilst maintaining the same mode of locomotion throughout life. These ontogenetic characteristics stimulate biomechanical questions about the strategies that allow emus to cope with their rapid growth and locomotion, which can be partly addressed via scaling (allometric) analysis of morphology. In this study we have collected pelvic limb anatomical data (muscle architecture, tendon length, tendon mass and bone lengths) and calculated muscle physiological cross sectional area …

Characterizing Fetal Sleep States Of Iugr And Low-Risk Fetuses Using Fetal Magnetocardiography, Bhargavi Sriram

Theses and Dissertations

Intrauterine growth restriction (IUGR) is a fetal condition characterized by growth-rate reduction. Afflicted fetuses tend to display abnormalities in heart rate. Hence, studying its heart rate variability (HRV) along with comparisons against normal fetal HRV might give some insight into the heart rate dynamics between the two groups. Heart rate variability (HRV) is one of the prominent markers that could help in identifying fetal distress. Four fetal heart rate patterns were previously defined based on HRV, which can provide clinicians with valuable information regarding fetus health during pregnancy. Past studies that differentiate the HRV with or without considering patterns, have …

Strain-Driven Growth Of Gaas(111) Quantum Dots With Low Fine Structure Splitting, Paul J. Simmonds

Physics Faculty Publications and Presentations

Symmetric quantum dots (QDs) on (111)-oriented surfaces are promising candidates for generating polarization-entangled photons due to their low excitonic fine structure splitting(FSS). However, (111) QDs are difficult to grow. The conventional use of compressive strain to drive QD self-assembly fails to form 3D nanostructures on (111) surfaces. Instead, we demonstrate that (111) QDs self-assemble under tensile strain by growing GaAs QDs on an InP(111)A substrate. Tensile GaAs self-assembly produces a low density of QDs with a symmetric triangular morphology. Coherent, tensile QDs are observed without dislocations, and the QDs luminescence at room temperature. Single QD measurements reveal low FSS with …

Enzymes From Fungal And Plant Origin Required For Chemical Diversification Of Insecticidal Loline Alkaloids In Grass-Epichloë Symbiota, Juan Pan, Minakshi Bhardwaj, Padmaja Nagabhyru, Robert B. Grossman, Christopher L. Schardl

Chemistry Faculty Publications

The lolines are a class of bioprotective alkaloids that are produced by Epichloë species, fungal endophytes of grasses. These alkaloids are saturated 1-aminopyrrolizidines with a C2 to C7 ether bridge, and are structurally differentiated by the various modifications of the 1-amino group: -NH₂ (norloline), -NHCH₃ (loline), -N(CH₃)₂ (N-methylloline), -N(CH₃)Ac (N-acetylloline), -NHAc (N-acetylnorloline), and -N(CH₃)CHO (N-formylloline). Other than the LolP cytochrome P450, which is required for conversion of N-methylloline to N-formylloline, the enzymatic steps for loline diversification have not yet been established. …
