A unified strategy for penostatin (Bio)synthesis and forays in computational chemistry
… fields of synthetic organic and natural products chemistry. Nuclear magnetic resonance (NMR) spectroscopy is unarguably the single most powerful spectroscopic tool for this task; however, the unambiguous assignment of these structural properties via spectroscopic data alone is rarely a trivial …

Structure and Dynamics of Layered Double Hydroxides
Layered double hydroxides (LDHs) are a complex group of phases with wide ranging technological applications and increasingly recognized geochemical significance. They are unusual among oxide and hydroxide phases in having large anion exchange capacities, and enhancing their application and …

An Investigation of the Singlet Delta Oxygen and Ozone Yields From the Pulsed Radiolysis of Oxygen and Oxygen-Noble Gas Mixtures
… production efficiency of 0.14% for direct nuclear pumping in an argon-oxygen mixture. Extensive modeling of the oxygen and argon-oxygen mixtures were benchmarked against these and other experiments. However, good agreement over a broad absorbed dose range was only possible if the O(,4)('+) …

TRU-ART: A cost-effective prototypical neutron imaging technique for transuranic waste certification systems
The certification of defense radioactive waste as either transuranic or low-level waste requires very sensitive and accurate assay instrumentation to determine the specific radioactivity within an individual waste package. The assay instruments that are currently fielded at various Department of …

Elemental Characterization of Municipal Solid Waste Incinerator Ash and Its Leachates Using Neutron Activation Analysis and Inductively Coupled Plasma Atomic Emission Spectroscopy
Incineration of municipal solid waste (MSW) is an increasingly attractive option for dealing with the burgeoning quantity of solid waste generated in the West. A combination of neutron activation analysis (NAA), inductively coupled plasma (ICP), and x-ray fluorescence (XRF) are used to analyze a …

Actinide porphyrin complexes
The first bis(porphyrin)actinide complexes have been prepared by reaction of M(NEt$\sb2$)$\sb4$ (where M = Th, U) with H$\sb2$TPP or H$\sb2$OEP. The coordination geometry of (TPP)$\sb2$Th is a distorted square-prism where the thorium center is displaced 1.47 A from each of the porphyrin N$\sb4$ …

Synthesis and evaluation of fluorine-18 labeled androgens as in vivo imaging agents for prostatic cancer using PET
In order to develop androgen receptor (AR) based probes for in vivo imaging of prostatic cancer using positron emission tomography (PET), four pairs of 16$\beta$- and 16$\alpha$-fluoro androgens, as well as two 20-fluoro androgens have been synthesized. The fluorination was achieved mainly by …

Nuclear Magnetic Resonance Studies of Imidazolium-Based Ionic Liquids and Garnet-Type Li7La3Zr2O12
… towards an improved energy storage technology. Nuclear magnetic resonance (NMR), is a sensitive and selective method to probe particle dynamics (magnetic relaxation, diffusometry, etc.) and material structures (spectroscopy) down to the atomic level. In this work, several NMR techniques are …

Spin Chemistry of Guest@Host Systems: H₂@C₆₀ and Nitroxide@Octa Acid
This thesis describes the nuclear and electronic spin chemistry of incarcerated guest molecules to form a guest@host complex in conjunction with the utility of nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) spectroscopy. The first chapter describes the background and …
