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) species with a bridging...
Applications of elemental analysis for archaeometric studies : analytical and statistical methods for understanding geochemical trends in ceramics, ochre and obsidian
(University of Missouri--Columbia, 2006)
, including INAA, and X-ray fluorescence spectrometry (XRF). Multivariate statistics of the data point to trends in the inter- and intra-source variability of ochre. Elemental results from Missouri, California, Oregon, Texas, Arizona, and Peru have been...
Radioactive Au for potential radiotherapeutic application
(University of Missouri--Columbia, 2010)
Radioactive gold-198/199 can be used in therapeutic radiopharmaceutical agents to combat cancer. In this thesis, two projects involving the development of radioactive gold-198/199 are described. The first project discusses ...
Copper (I) coordination networks synthesized with solid-solid reactions
(University of Missouri--Columbia, 2008)
The use of solid-solid reactions in the development of one-, two-, and three dimensional Cu(I) coordination networks are discussed. The solid-solid reactions were monitored by a variety of instrumental techniques to achieve ...
Ammonia elimination from protonated nucleobases
(University of Missouri--Columbia, 2007)
The dediazoniations of the diazonium ion 1 of 4-aminopyrimidine and of the tautomeric cytosinediazonium ions 2 and 3 are facile and result in the formations of cations 4, 5, and 6. The pyrimidine ring-opening of 4, 5 and ...
Organo nickel and platinum chemistry at the edge of corannulene
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Corannulene (C[subscript 20]H[subscript 10]), a polycyclic aromatic hydrocarbon (PAH) is a bowl shaped fullerene fragment. This work involves investigations into the chemistry...
Computational studies of three chemical systems
(University of Missouri--Columbia, 2011)
The subject of this dissertation is the use of electronic structure calculations to examine and supplement the experimental observations of three different chemical systems. Both ab initio and DFT methods have been employed. ...
Novel techniques for cold/ultracold molecular collisions

Synthesis and photochemistry of PT (IV) hydroxo complexes
(University of Missouri--Columbia, 2015)
Global energy consumption and the production of clean renewable energy have become greater challenges. Sunlight-induced splitting of water into H2 and O2 is one of the leading strategies to achieve clean and renewable ...
Intermolecular (4+3) cycloaddition reaction of oxidopyridinuim ions with silylated dienes, exploring the oxidation chemistry and photochemistry of cycloadducts
(University of Missouri--Columbia, 2022)
carbon was unsuccessful. Based on the proposed mechanism and the product formation, HFIP acted as the nucleophile. An extension of the aforementioned study investigated the efficacy of the (4+3) cycloadducts as reactants in a [2+2] photocycloaddition...
Investigation of K₀ NAA at MURR and investigation of the toenail as a biomonitor for Mg, Zn, Cu, Se and Hg
