Phosphinimines as potential technetium environmental sensors
(University of Missouri--Columbia, 2007)
Phosphinimines, R₃P=NSiMe₃, undergo hydrolysis to form the phosphiniminiumcation, R₃P=NH₂+, which forms the ion pair [R₃P=NH₂+][X-] in the presence of an anion.Preliminary studies show that in the presence of TcO₄-, ...
Arsenic-72, 77 as a matched pair radiopharmaceutical for imaging and radiotherapy
(University of Missouri--Columbia, 2018)
] The parameters for a 72Se/72As generator were evaluated and nca 72Se was produced via the 70Ge([alpha], 2n)72Se nuclear reaction, separated and loaded onto a generator column. Further evaluations are underway. Radiochemistry of nca 72,77As will be discussed...
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 ...
Anisotropic shock response of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB)
(University of Missouri--Columbia, 2020)

Purification and characterization of A[beta] and probing the interactions between myricetin and A[beta] using various spectroscopic methods
(University of Missouri--Columbia, 2009)
[beta] fragments, A[beta](1-16) and A[beta](25-40), together with A[beta](1-42) were investigated. HPLC purification was conducted on crude A[beta](1-16) and A[beta](25-40) using a Beckman System Gold HPLC system, a Vydac C18 column and a combination...
Determination of total selenium and seleno-amino acids in yeast and aquatic organisms by liquid chromatography and inductively coupled plasma mass spectrometry
(University of Missouri--Columbia, 2007)
The primary goal of this dissertation research was to develop methods for routine speciation analysis of selenium in tissues. A method for total selenium using on-line stable isotope dilution analysis with conventional ...
Theranostic and matched pair radionuclides as radiopharmaceutical as for imaging and radiotherapy
(University of Missouri--Columbia, 2020)
The main focus of this dissertation is on the development of arsenic and rhenium radiopharmaceuticals as potential theranostic candidates. Chapter 2 focuses on 72,77. As radiopharmaceuticals for potential PET imaging and ...
Studies and synthetic methodology of Nampt inhibition
