The Design, Synthesis and Application of Redox-Responsive MRI Contrast Agents 

Yu, Meng (2015-07-29)
Reactive oxygen species (ROSs), such as hydroxyl radicals, superoxide anions and hydrogen peroxide, are side products of aerobic respiration. Although ROSs regulate several physiological processes, they have been implicated ...

Development and Synthesis of Mononuclear Superoxide Dismutase Mimics and Magnetic Resonance Imaging Contrast Agents 

Hutchinson, Tessa (2021-04-26)
Over the past few years the Goldsmith group has reported mononuclear superoxide dismutase mimics and Mn(II) complexes with redox-active quinols that display rapid T1- weighted responses to H2O2. This dissertation will ...

Dioxygen reduction and Superoxide dismutase mimicry using first row transition metal complexes with redox active organic ligands. 

Obisesan, Segun (2024-04-22)  ETD File Embargoed
The efficient activation of small molecules, such as dioxygen (O2) and superoxide (O2-), is key to solving several energy- and health-related challenges. The selective reduction of O2 to water (H2O) is integral to the ...

Dual Mode Redox-Responsive MRI Contrast Agents 

Polander, Hillary (2022-08-05)
Magnetic resonance imaging (MRI) contrast agents function by shortening the relaxation times of targeted nuclei, thereby better distinguishing regions with different local concentrations of the visualized nuclei. ...

Manganese and Iron Coordination Complexes for Biological Imaging and Oxidative Catalysis 

Zhang, Qiao (2014-04-23)
The ligand N,N’-bis(2-pyridylmethyl)-bis(ethylacetate)-1,2-ethanediamine (debpn) coordinates divalent transition metal ions in either a pentadentate or hexadentate fashion. The coordination number correlates with the ionic ...

Metal Complexation and Extraction Studies of bis-dithiophosphinite Ligands 

DeVore, Michael, II (2011-12-06)
Five bis(dithiophosphonite) ligands OR1a-OR3b were synthesized using Lawesson’s Reagent and analogs of Lawesson’s Reagent. Two of the ligands OR2a and OR3a, were used in extraction studies with uranyl nitrate. UV-Vis ...

A Novel Halogenation Protocol and Non-heme Iron Hydroxylase Mimics as Catalysts for C-H Oxidation and O2 Activation 

He, Yu (2012-08-03)
Hydrocarbons react with molar concentrations of peracetic acid and halide salts to yield predominantly monohalogenated products under optimum conditions, with chlorination being more oxidatively efficient than bromination. ...

Synthesis and Electrochemical Characterization of Ternary Metal Oxides 

Bredar, Alexandria (2021-04-14)
Metal oxides are an incredibly diverse class of materials that have found significant utility in the development of emerging solar conversion technologies. Their varied electronic properties allow them to function as charge ...

Transition Metal Manganese and Main Group Gallium Complexes as Catalysts for Alkene Epoxidation 

Jiang, Wenchan (2013-04-29)
Epoxides are important organic synthesis precursors and widely used in industry. Alkene epoxidation has been under extensive investigation over decades. Synthetic models have been established for catalytic epoxidations, ...
