Radionuclide production for radioisotope micro-power source technologies
(University of Missouri--Columbia, 2008)
Radioisotope micro-power sources (RIMS) hold great promise for the development of small power sources for use in numerous applications, including micro electromechanical (MEMS) systems, due to the five orders of magnitude ...
Structural studies of acid phosphatases from pathogenic bacteria
(University of Missouri--Columbia, 2007)
Acid phosphatases are important, ubiquitous, and diverse group of enzymes that catalyze the transfer of phosphoryl from phosphomonoester to water forming inorganic phosphate and alcohol. These enzymes play critical roles ...
Sixteen valence-electron species containing boron: structural diversity abounds
(University of Missouri--Columbia, 2005)

(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Oxidation of N-alkyl and N-aryl sulfoximines and 1,5-hydride shift of S-alkenyl sulfoximines have been studied. Oxidation of N-alkyl sulfoximines using ...
Determination of trace elements levels in plasma from larvae in the course of baculoviral and bacterial infections by inductively coupled plasma-mass spectrometry (ICP-MS)
(University of Missouri--Columbia, 2009)
While a number of studies have examined the effect of infections on the trace elements status of mammals, not any similar study in insects are found. In this study, we used inductively coupled plasma-mass spectrometry ...
Variable-temperature [superscript 1]H-NMR and AB initio study of 5-amino-imidazole-4-carboxamide (AICA) : competing paths for amide-H scrambling
(University of Missouri--Columbia, 2008)
5(4)-aminoimidazole-4(5)-carboxamide (AICA and TAICA) is an important precursor for the synthesis of purines in general and of the nucleobases adenine and guanine in particular. Biotic nucleobase synthesis has been studied ...
Core-based hyperbranched polyethyleneimine coating in capillary electrophoresis
(University of Missouri--Columbia, 2009)
In capillary electrophoresis (CE), chemical and dynamic modification of a fused silica surface can be used to control the electroosmotic flow (EOF), to minimize the interaction of analytes with the capillary surface and ...
Synthesis of silyloxyacrolein for [4+3] cycloaddition and preparation of carbonate closomer
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Followed by Funk's method, I synthesized silyloxyacroleins and used them as dienophiles to react with different dienes in [4+3] cycloaddition reaction. ...
Spectroscopic investigations of acrylodan dye interactions with poly(amidoamine) and poly(propyleneimine) dendrimers
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The novel molecular architecture of dendrimers facilitates use in many applications. Using the solvatochromic probe phenol blue, the first direct ...
pH sensitive fluorescent sensors
(University of Missouri--Columbia, 2007)
Pheochromocytoma is a cancer of the adrenal gland. Pheochromoocytomas produce a variety of catecholamines, including norepinephrine. The result is high blood pressure which is caused by the release of catecholamines into ...
Structure and synthesis of four supramolecular structures involving Cu(I) and 4,7-phenanthroline
(University of Missouri--Columbia, 2007)
The design and synthesis of supramolecular species with discrete geometric shapes has been an area of much interest and research in recent years. Three isolated species of square shaped molecules and one infinite network ...
Spectroscopic investigations of the beta-amyloid peptide
(University of Missouri--Columbia, 2008)
The focus of this project is two-fold: examining the native structures of three different fragments of the beta-amyloid (A[beta]) peptide, and attempting to overcome some of the difficulties encountered in such an examination. ...
