SYNTHESIS AND CHARACTERIZATION OF NOVEL NITROGEN-CONTAINING LIGANDS FOR METAL ION SEPARATIONS
A serious limiting factor in the continued development of nuclear power is the disposal of high-level radioactive waste from spent nuclear fuel. The PUREX process can be used for the recovery of U and Pu, but it does not separate the other byproducts of fission which are potentially useful, but currently cause most of our problems with radioactive waste. An important complicating factor is the presence of large amounts of lanthanides in dissolved spent nuclear fuel. The separation of lanthanides (Ln) from actinides (An) is therefore critical to the future of nuclear power.

SYNTHESIS, MOLECULAR BIOLOGY, AND BIOANALYTICAL STUDIES OF A FLUORESCENT SEROTONIN LIGAND WITH 5-HT3A IN BULK AND SUPPORTED LIPID BILAYERS
The first part of this dissertation is based on the synthesis, characterization and binding of a fluorescent ligand (5-HT*) that binds to a recombinant Serotonin type 3 Receptor (5-HT3A). Here a linker and a fluorescent tag was added to the indole nitrogen of 5-Hydroxytryptamine (5-HT), an agonist of 5-HT3A. Next the affinity purified receptor in solution was used and the binding of the ligand to the receptor was studied using luminescence spectroscopy, obtaining a Kd of 83 + 3 nM and a Hill Coefficient n = 3. Also described are results obtained from the binding of this fluo
Crystal Engineering: Synthesis and Structural Analysis of Coordination Polymers with Wavelike PropertiesChemistry
6/4/2012 4:10 p.m. to 5:00 p.m.
Fulmer Hall 210
Dr. Omar W. Steward
Department of Chemistry and Biochemistry
Bayer School of Natural and Environmental Sciences
Supramolecular coordination polymers with wavelike structures have been synthesized by self-assembly and their structures analyzed using the sine trigonometric function.
Discussion will also briefly touch on the importance of X-ray diffraction in the development of modern inorganic chemistry.
