Effects of transition metal cationization on peptide dissociation by mass spectrometry

Watson, Heather Malone (University of Alabama Libraries, 2011)

Peptide sequencing is fundamental to understanding a protein's structure and function. The field of proteomics is dedicated to how these aspects relate to human health and disease. Unfortunately, the majority of peptides ...
Electrical characterization of large-area donor-acceptor molecular junctions

Johnson, Marcus Shabazz (University of Alabama Libraries, 2016)

The electrical properties of five different donor – bridge – acceptor large-area monolayer molecular junctions show current rectification. Langmuir-Blodgett deposition onto thermally evaporated gold yielded four out of the ...
Electrochemical and spectroscopic studies of bodipy dyes and nanostructured electrodes for solar energy harvesting and conversion

Kaneza, Nelly (University of Alabama Libraries, 2018)

The use of fossil fuel-based technologies has contributed to the increase in the concentration of greenhouse gases, especially CO2, causing global climate change. To achieve the global energy demand, advanced energy ...
Electrochemically assisted self assembly of mesoporous silica on conducting substrates as templates for electroactive metal oxides

Cordes, Nikolaus Lynn (University of Alabama Libraries, 2012)

Three dimensional, conductive, macroporous nickel foams and mesoporous carbon aerogels have been utilized as skeletal supports for an electrochemically assisted deposition of mesoporous silica particles and films. ...
Electrochromic and photoelectrochromic switching devices based on aryl amine redox chemistry

Kelley, Melody (University of Alabama Libraries, 2014)

Electrochromic Materials are of interest as fundamental components in smart windows, displays, and fabrics. A new class of organic arylamine molecular electrochromes (both ionic and neutral) has been developed to afford ...
The Electrolytic Oxidation of Potassium Arsenite

Adams, Marion Vaun (University of Alabama Libraries, 1924)

Potassium arsenate is a comparatively unknown compound, that is, very little experimental work has been done with it, and since no important use has been found for it no attempt has been made to produce it in large quantities. ...
Electron paramagnetic resonance investigation of semiquinone intermediate in mitochondrial cytochrome bc1 complex

Vennam, Preethi Reddy (University of Alabama Libraries, 2012)

The Rieske/cytochrome b complexes, also known as cytochrome bc complexes, catalyze a unique oxidant-induced reduction reaction at their quinol oxidase (Qo) sites, in which substrate hydroquinone reduces two distinct electron ...
Electron paramagnetic resonance studies of drug binding in cytocrhome P450 enzymes

Lockart, Molly Marie (University of Alabama Libraries, 2019)

Cytochrome P450 enzymes (CYPs) are heme-containing monooxygenase enzymes that exist in nearly every living organism. They are responsible for oxidizing a wide variety of substrates in biosynthetic and detoxification pathways ...
Electron spin-lattice relaxation of trityl radicals

Chen, Hanjiao (University of Alabama Libraries, 2017)

Tris(2,3,5,6-tetrathiaaryl)methyl radicals (trityls) belong to a family of persistent free radicals that have been widely used in a number of magnetic resonance applications because of their relatively narrow EPR line ...
Electron transfer dissociation and collision-induced dissociation mass spectrometry of metallated oligosaccharides

Duke, Ranelle Marie (University of Alabama Libraries, 2019)

Investigations of metallated glycans through tandem mass spectrometry (MS/MS) can further the field of glycomics, the sequencing of the human glycome. The field is hindered by the lack of an analytical technique that can ...
Electron transfer dissociation mass spectromerty studies of peptides

Feng, Changgeng (University of Alabama Libraries, 2014)

Electron transfer dissociation (ETD) is an important tandem mass spectrometry technique in peptide and protein sequencing. In the past, ETD experiments have primarily involved basic peptides. A limitation of ETD is the ...
Electron-deficient conjugated materials

Cao, Hongda (University of Alabama Libraries, 2018)

The development of new conjugated materials with tailored properties is in high demand for applications in organic electronics. This has led to conjugated materials receiving a great deal of research attention over the ...
Electron-deficient heterofluorene conjugated polymers and small molecules

Cassidy, Stephen Joel (University of Alabama Libraries, 2018)

A series of heterofluorene polymers, containing electron-deficient heteroatoms, were designed for investigation. Indium was first chosen for heteroatom substitution, due to the known Lewis acidity of Group-13 elements, and ...
Electronic structure investigations of titanium oxide nanoclusters, boron-nitrogen heterocycles, and reaction products of lanthanides with oxygen difluoride and lanthanides with water

Mikulas, Tanya C. (University of Alabama Libraries, 2015)

Advanced electronic structure methods on high performance computers have been used to predict the reactions of lanthanides, properties of liquid chemical hydrogen storage systems, and Fe doped TiO2 nanoclusters. Chapter 2 ...
Enhancing energy harvesting and conversion efficiencies of heterogeneous photocatalysts for solar water splitting using surface plasmon resonance and cathodic reduction methods

Wang, Jue (University of Alabama Libraries, 2015)

This dissertation presents surface enhanced photocatalytic characteristics of heterogeneous catalysts (e.g., α-Fe2O3 and CdS) for solar water splitting. The enhancement can be obtained by either incorporating plasmonic ...
ESI-MS and EPR spin trapping study of xanthophylls: structural and environmental impacts on reactivity

Magyar, Adam S. (University of Alabama Libraries, 2015)

Carotenoids are lipophilic pigments that provide many of the colors found in nature, including the colors found in plants, flowers, and animals. The main interest in carotenoids concerns their participation in light ...
Experimental and theoretical studies on the electronic properties and dissociation reactions of gas-phase metal oxide nitrate complexes

Hester, Thomas Hinton (University of Alabama Libraries, 2016)

This dissertation discusses dissociation studies performed on various gas-phase transition and main group metal nitrate anion complexes using a tandem mass spectrometer. The dissociation of these complexes, via consecutive ...
Fluoroalkoxy-functionalized carbenes for main group and transition metal complexes

Runyon, Jason W. (University of Alabama Libraries, 2011)

This dissertation recounts the synthesis and use of imidazol-2-ylidenes for their applications as ligands for main group elements and transition metals and as sterically hindered Lewis bases for hydrogen activation. Chapter ...
Functional and regulatory mechanisms in alpha-isopropylmalate synthases

Casey, Ashley Kay (University of Alabama Libraries, 2014)

The allosteric regulation of a protein is where the binding of a molecule at a distal site affects the physical and chemical properties at the binding site. A model system for studying allosteric mechanism is isopropylmalate ...
Functional ionic liquids for use in pharmaceutical applications

Hough, Whitney Lauren (University of Alabama Libraries, 2010)

For years, the pharmaceutical industry has relied heavily on crystalline active pharmaceutical ingredients (APIs) that can be approved by the Federal Drug Administration (FDA) as neutral compounds, salts, or solvates of ...
