Coulomb explosions dynamics
(University of Missouri--Columbia, 2022)
results in four fragments upon absorption a single photon. Here, with the initial analysis of diffraction images, and comparison with the theory, we confirmed a concerted four-body dissociation channel as the main mechanism....
Ligands for the sigma receptor and the mu-opioid receptor
(University of Missouri--Columbia, 2007)
The sigma receptor is a unique receptor family with two subtypes: sigma-1 and sigma-2. In order to conduct structure-activity relationship studies (SAR), a series of specific 1-phenylpropyl-4-benzylpiperidine and 1-phenylpropyl-4- benzylpiperazine...
Method development for the analysis of nuclear forensic signatures with ICP-MS
(University of Missouri--Columbia, 2022)
Nuclear forensic analysis is a field of analytical chemistry that focuses specifically on analyzing signatures of nuclear material for criminal investigation. Promising nuclear forensic signatures include rare earths element ...
Solid, aqueous, and gaseous: functional materials and advancements to reduce pollution in three forms
(University of Missouri--Columbia, 2022)
and materials that are creative and multifunctional. In as much as possible, I have given thought to the feasible real-world applicability of this work. Firstly, I have produced and characterized an extensive series of activated carbons using waste plastics...
Design and construction of multicomponent spheroidal assemblies on the nano-scale via the self-assembly approach
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Supramolecular chemists can be thought of as the architects of the nano-scale world. We are primary concerned with the design and construction of various nanostructures based...
Nitrosative guanosine deamination : pyrimidine ring opening implications of effects in homogeneous solution as well as anisotropic environments
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In recent years a great deal of interest has been focused on the exposure to nitrous acid (HNO2), nitric oxide (NO) and other nitrosating species because they are mutagenic...
Synthesis and reactivity of low-valent uranium and neptunium complexes
(University of Missouri--Columbia, 2019)
Chapter 1 reports the synthesis and characterization of U(IV) and Np(IV) selenium bis(phenolate) complexes. The reaction of the U(IV) complex with half an equivalent of p-benzoquinone results in the formation of a U(V)--U(V) ...
UF-CRDS: a pulsed uniform supersonic flow apparatus coupled with continuous-wave cavity ringdown spectroscopy
(University of Missouri--Columbia, 2022)
flow system which is produced by means of a high throughput piezoelectric stack valve combined with a Laval nozzle. In addition to the Laval nozzles built in collaboration with Dr. I.R. Sims from University of Renne, 3D printed Laval nozzles designed...
Technetium and rhenium schiff base complexes for nuclear medicine
(University of Missouri--Columbia, 2019)
This dissertation investigates the synthesis of rhenium and technetium Schiff base complexes for potential applications in nuclear medicine. In Chapter 2, a series of mixed ligand Re(III) complexes of the form trans-[Re(PR3)2(tmf2en)]+ were prepared...
Studies of natural products that reveal novel strategies for efficient modification of DNA
(University of Missouri--Columbia, 2006)
DNA is the central molecule in cells. The correct function of cells depends on the structure of DNA. DNA damaging natural products often show cytotoxic or mutagenic properties, which many times land them medicinal value ...
High valent uranium dioxo and imido complexes : synthesis and structure
(University of Missouri--Columbia, 2008)
Early actinide elements have attracted considerable attention in recent years due to the need for rigorous advancements in spent nuclear fuel recycling and remediation technologies, and for their emerging versatility in ...
