Novel Charge Carriers for Aqueous Electrochemical Energy Storage

Creator:: Sandstrom, Sean K.
Abstract:: The continued long-term use of fossil fuels as a primary energy source has resulted in dramatic increases in greenhouse gas emissions and the associated concerns of climate change and environmental pollution. A key strategy to circumvent these issues is a global shift away from fossil fuels toward renewable energy sources....

A Pyrone Diels–Alder Approach to Substituted Indoles and Carbazoles and the Synthesis of New Ropinirole Analogues

Creator:: Points, Gary L., III
Abstract:: Aromatic heterocycles are core structural motifs in natural products, pharmaceuticals and biological polymers. Indoles, in particular, represent a significant subclass of aromatic heterocycles, both in terms of sheer numbers, but also in biological and pharmaceutical relevance. As such, new methodologies for the synthesis of indoles represent an important and continually...

Efficient Fabrication of Nanoporous Si and Si/Ge Enabled by a Heat Scavenger in Magnesiothermic Reactions

Creator:: Luo, Wei, Wang, Xingfeng, Meyers, Colin, Wannenmacher, Nick, Sirisaksoontorn, Weekit, Lerner, Michael M., and Ji, Xiulei
Abstract:: Magnesiothermic reduction can directly convert SiO₂ into Si nanostructures. Despite intense efforts, efficient fabrication of highly nanoporous silicon by Mg still remains a significant challenge due to the exothermic reaction nature. By employing table salt (NaCl) as a heat scavenger for the magnesiothermic reduction, we demonstrate an effective route to...

Himeradine A : synthetic efforts towards himeradine A and related natural products, a Michael reaction focused approach

Creator:: Collett, Nathan D.
Abstract:: Lycopodium alkaloids have generated enormous amounts of interest from the scientific community, both as synthetic targets and for their medicinal properties. Herein is described work towards a unifying approach to large segments of the Lycopodium family. An organocatalyzed intramolecular heteroatom Michael reaction method, for the construction of piperidine and piperizine...

Electrochemical Advancement of Solid State Ion Selective Electrodes

Creator:: Bahro, Christopher
Abstract:: The general theme of this dissertation is the development of new analytical sensors to quantitatively study biological and environmental samples in aqueous and non-aqueous environments. A platinum ultramicroelectrode (UME) and a unique carbon-based pH microprobe were used to design a new SECM-based electrochemical bioassay. The Pt UME was used to...

Intercalation, exfoliation, and nanocomposites of layered inorganic compounds

Creator:: Sukpirom, Nipaka
Abstract:: The melt intercalation of poly(ethylene oxide) (PEO) between layers of MoO₃ and MPS3 (M=Mn,Cd) is obtained by heating the ground mixture and LiₓMoO₃, KₓMn₁-ₓ/₂PS₃, or KCd₁-ₓ/₂PS₃. The products are characterized by powder X-ray diffraction (XRD). Below the melting temperature of PEO (66 °C), intercalation rates and yields are low. By...

Total Synthesis of Isotopologues of Xanthohumol and its Congeners for Biological Studies

Creator:: Plagmann, Layhna S.
Abstract:: Xanthohumol [XN, (E)-6´-methoxy-3´-(3-methylbuten-2-yl)-2´,4´,4´´-trihydroxychalcone], the principal prenylated chalcone from hops, and its 2,3-dihydro- (DXN) and O6-desmethyl-2,3-dihydro- (DDXN) congeners, are of potential utility for the amelioration of metabolic syndrome; however, their complex bioactivity profiles cannot be properly studied and understood without access to appropriately produced synthetic materials. In the first part of...

Development of novel analytical methods to detect emerging contaminants in aqueous environmental matrices using large-volume injection

Creator:: Backe, Will J.
Abstract:: It is the responsibility of humans, as environmental stewards, to monitor our impact on the environment so that efforts can be made to remediate the effects of our actions and change behaviors. To better understand our environmental footprint, sensitive and simple analytical methods are needed to quantify the contaminants that...

Isolation, purification, and structure elucidation of hop plant elicitor

Creator:: Su, Hong, 1960-
Abstract:: Hop cell wall material (CWM) extracted from hop leaves (hamulus lupulus) was purified and characterized. The total sugar content, uronic acid content and monosaccharide composition of the CWM were determined. Galacturonic acid is the major component in the CWM. A mixture of unsaturated oligogalacturonides were released from purified hop CWM...
