NMR/MRI SIGNAL ENHANCEMENT BY REVERSIBLE EXCHANGE (SABRE) AND HETEROGENEOUS SABRE (HET-SABRE)
Signal Amplification by Reversible Exchange, or SABRE, is a type of PHIP (ParaHydrogen Induced Polarization) pioneered by Duckett, Green, and co-workers where an organometallic catalyst is used to co-locate parahydrogen (pH2) and a molecular substrate to be hyperpolarized. Like traditional PHIP, …

Using SABRE in NMR and MRI
This thesis describes the use of SABRE as a hyperpolarisation technique in both NMR spectroscopy and MRI. Hyperpolarisation is a method of generating enhanced magnetic resonance signals to improve signal to noise, contrast and resolution within those techniques. The primary aim of this thesis was …

NOVEL EXPERIMENTAL APPROACHES AND THEORETICAL MODELS FOR IMPROVING SENSITIVITY AND INFORMATION CONTENT OF NMR AND MRI SPECTROSCOPY
… of signal amplification by reversible exchange (SABRE) was investigated. The reproducibility of this recent discovery has been examined and new conclusions about the mechanism of this technique are delineated. NMR signal enhancements of nearly ~400-fold are reported. Moreover, a new water soluble …

A spinoffs study applied to the airline industry
… and of American Airline's distribution system Sabre. These three cases illustrate some of the key issues that must be carefully considered when spinning off a subsidiary. The thesis concludes that spinoffs are a smart strategy when the focus of the spun off division is different from that of …

Wildflower establishment on landfills in central and southwestern Virginia
Municipal solid waste landfills are convenient means of disposing of society's waste; once closed, they become a liability to the community due to attributes which contribute to soil and water contamination. Regulations state that adequate vegetation be used to maintain the integrity of the soil …

Cobalt catalysts towards parahydrogen induced polarization
Magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) spectroscopy are two techniques that hold great importance to the fields of medicine and chemistry, respectively. Used daily by researchers and medical practitioners alike, these techniques provide critical diagnostic information …
