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) species with a bridging...
Measurement of radionuclides in biological tissues from occupationally exposed individuals
(University of Missouri--Columbia, 2022)
-documented actinide exposures needs to be studied. In addition to measurement of actinide concentrations, the isotope ratios 240Pu/239Pu, 235U/238U, and 236U/238U provide information that is useful for discriminating between actinide sources and americium measurement...
Oxidative DNA damage by 1-hydroxyphenazine, virulence factor of Pseudomonas aeruginosa : towards a molecular understanding of the bacterial virulence factor 1-hydroxyphenazine
(University of Missouri--Columbia, 2008)
1-Hydroxyphenazine is a secondary metabolite and virulence factor of Pseudomonas aeruginosa. This organism colonizes the airways of the patients of cystic fibrosis and causes progressive destruction of the airways. It is ...
The synthesis and characterization of 1,1'-disubstituted ferrocene imine Schiff base ligand systems for use as potential environmental heavy metal cationic sensors
(University of Missouri--Columbia, 2008)
through three means: proton nuclear magnetic resonance (1H NMR), ultraviolet-visible spectroscopy (UV-Vis) and cyclic voltammetry (CV). While a working universal heavy metal sensor was not achieved during this research project, it advanced the progress...
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 ...
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)
