Many industrially important heterogeneous catalytic reactions are not well understood. This lack is mainly due to the high reactivity and transient nature of the reactive sites and chemical intermediates involved. Monolithic, sol-gel...
This dissertation studies the size- and site-dependent optical and magnetic properties of II-VI quantum dots (QDs). The first chapter provides a theoretical background used to analyze the data and the properties expected for diluted...
One of the mechanisms of cardiac arrhythmias is the self-organization of electrical waves in the heart. These waves can anchor to scar tissue, collagen fibers, and coronary vessels. The anchoring generates stationary electrical signals...
Materials synthesis far from thermodynamic equilibrium can yield hierarchical order that spans from molecular to macroscopic length scales. Here we study the formation of microscopic and macroscopic inorganic tubes during spatially...
Metal flux synthesis was used to discover new Zintl phase materials and to grow crystals of superconducting phases. Reactions of barium and the pnictide elements Pn = P or As in indium melts produced new Zintl phases Ba2In5Pn5. This...
Phosphorous is one of the most important nutrients in the natural environment. It is often the limiting nutrient in many environmental systems. Recently, it has been recognized that organic phosphorus compounds play a more important role...
This dissertation presents and evaluates the unique interplay between nanoparticle structure, environment, and electronic energy relaxation. This knowledge will provide useful information for tailoring nanoparticle properties so that...
Metal eutectic fluxes are useful for exploratory synthesis of new intermetallic phases. In this work the use of cerium/transition metal eutectics such as: Ce/Co, Ce/Ni, and Ce/Fe have yielded many new synthetically and magnetically...
Evaluation of Extraction Method and Characterization of Water Soluble Organics from Produced Water by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
With world consumption of crude oil at over 30 billion barrels per year, 2 petroleum provides the backbone for a multi-trillion dollar industry. However, this entire industry is built around the ability to convert crude oil into useful...
This dissertation studies the optical and magnetic properties of CdSe, including alloys which incorporate Mn (II) and sulfur. The first chapter explains the theory used to analyze the data and the properties expected for condensed phase...
The flux method is a very useful technique for the exploratory synthesis of rare earth intermetallics. Reactions of rare earth metals with iron and silicon (or germanium, tin, lead) in a 1:1 Mg/Al flux have yielded single crystals of a...
Magnetic materials are used in many applications such as credit cards, hard drives, electric motors, sensors, etc. Although a vast range of magnetic solids is available for these purposes, our ability to improve their efficiency and...
Few studies have examined how physical activities of family members affect the overall functioning of a family in general. This study utilized a family-systems perspective with the idea that what happens in one area of family system will...
The formation of stable bound wave packets is studied in a modified Belousov-Zhabotinsky reaction. These densely stacked structures arise from an attractive interaction between oxidation pulses that is not known from the classical...
Multiferroic materials are rare compounds featuring at least two ferroic properties with a majority of them displaying (anti)ferro – electricity or magnetism. Currently, the most famous compounds displaying such be-havior are oxide...
Various analytical techniques have been employed to probe the chemical identity and characteristics of complex Dissolved Organic Matter (DOM) mixtures. With continuing advances in readily available highly developed mass spectrometers, ...
Natural organic matter (NOM) exists as a highly functionalized, polydisperse and complex mixture of organic compounds derived from decaying plan and animal detritus. NOM has been characterized by Fourier transform ion cyclotron resonance...
Zeolite structures consist of a negatively charged, porous, aluminosilicate framework with the ability to ion exchange its charge balancing cations. However, problems associated with traditional methods of aqueous ion exchange can...
Although still in a developing age, solid-state nuclear magnetic resonance (NMR) spectroscopy has been proved to be a powerful tool to study the structure and dynamics of membrane proteins. Here this technique is applied to investigate...
Fourier Transform Ion Cyclotron Resonance Mass Spectrometry Instrumentation and Methods for Structural Characterization of Trapped Biomolecular Ions: Innovative MS/MS Techniques, Gas-Phase Hydrogen/ Deuterium Exchange, and Laser-Induced Fluorescence
Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has become a powerful tool for biomolecular structural characterization because of its superior mass resolving power and high mass accuracy. Of particular interest...
Atomic structures of biological systems can be obtained by several experimental methods, X-ray crystallography being one of the most widely used. Crystallography can provide a high resolution visualization (better than 1 A), but for...
Multiply-bonded metal-ligand systems such as akylidyne, amido, and imido groups have long been proposed as key intermediates in heterogeneous catalytic reactions such as olefin metathesis1, 2, polymerization1, and ammoxidation.1, 3, 4...
Diphtheria toxin repressor protein (DtxR) is a 226 amino acid protein that regulates the genes for iron uptake in Corynebacterium diphtheria and also regulates the Diphtheria toxin production. The known functions of this protein include...
This, the 30th year of Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR MS), 1 has marked a milestone for incredible growth in the field of high-resolution mass spectrometry. The most notable realizations of this fact...
Piperidine-2, 6-dicarboxylic acid (PDA), 2, 6-dicarboxypiperidine-N-acetic acid (DPA) and chelidamic acid (CA) were characterized using a variety of techniques. The acid dissociation constants of these ligands were determined by...
The next generation of sensors built upon nanotechnology is rapidly coming to the forefront of scientific applications, with particular application to contemporary global concerns including counterterrorism and device miniaturization....
The main emphasis of this research was to explore molten metals (flux) as a growth medium for single crystal intermetallics. The primary characterization methods included: SEM-EDS, X-ray Diffraction, and SQUID magnetometry. The main...
Cross polarization (CP) has been widely used to enhance the polarization of dilute nuclei S with low gyromagnetic ratios from abundant nuclei I with higher gyromagnetic ratios. Efficient CP transfer is generally achieved by spin locking...
