Abstract Details

2011, PhD, University of Cincinnati, Arts and Sciences: Chemistry.
Part I. Heterogeneous, sulfated polysaccharides have attracted significant attention in light of their various biological activities. Of these, heparin has been used extensively as an anticoagulant for decades and is thought to have numerous additional, therapeutic activities. The work detailed in Part I of this dissertation describes several investigations designed to advance the state of heparin analysis through the use of various circular dichroism (CD) based methods. Each of the chapters in Part I, and throughout this dissertation, are meant to provide complementary information while also standing independently. Part II. Modern nuclear forensic investigations are heavily dependent on the use of a wide variety of analytical techniques. These methods are useful in determining the key features for seized nuclear materials, including elemental composition, isotopic enrichment, and age. Such information is invaluable in determining the source of a material, the route it has traveled since production, and its intended use. The ability to conduct nuclear forensic investigations proficiently represents a significant deterrent to groups seeking to carry out a nuclear attack and would be required in responding to an event, should one take place. Several issues exist, however, that will challenge the success of future nuclear forensic efforts. These challenges range from political considerations to the need for new field deployable measurement technologies. Chapter 7 provides a brief overview of several analytical approaches used in nuclear forensics. The introduction to these methods highlights several of the laboratory challenges facing nuclear forensics as well potential future directions for the field. Discussed concepts include separations, counting techniques, mass spectrometry, and alternative approaches to fully characterizing nuclear materials. Chapter 8 discusses the use of alpha spectrometry to critically evaluate a 233U standard reference material as a potential uranium/thorium double tracer system for age-dating uranium materials based on the in-growth of thorium progeny. Collected results provided the age of the reference material and revealed several deficiencies associated the proposed double tracer concept. A discussion of these considerations and the age-dating results is included in this chapter.
