Polyion sensors based on induced ion extraction

Creator:: Fordyce, Katherine
Abstract:: A novel method for detecting the peptidase activity of clinically relevant peptidases was investigated using solid-contact electrochemical polyion sensors under chronopotentiometric control. Complete instrumental control over ion-extraction was accomplished by incorporating a lipophilic electrolyte into the ion-selective membrane; the sensors had no intrinsic ion-exchange capabilities. The sensors were used to...

Using Computational and Statistical Methods as an Aid to Study Environmentally Relevant Organic Molecules

Creator:: Dorn, Shelby E.
Abstract:: In this report, three studies are presented that utilize computations to predict transformations, identities, and properties of environmental organic molecules. Each study shows how computations can lead to models of chemical behavior. The importance of this research is rooted in the need for understanding how human behavior and health intersect...

Computational Rationalizations of Mechanism and Stereocontrol in Small-Molecule Lewis Base Organocatalysis

Creator:: McCauley-Walden, Daniel W.
Abstract:: My work has focused on investigating synthetic organic reactions using applied computational methods. Non-covalent interactions are critical to catalysis, mechanism, and stereoselectivity, with the most prominent interaction for isothioureas being the S···O contact between the catalyst sulfur atom and the oxygen of the acyl group. A comprehensive joint experimental and...

Computational Investigation and Prediction of Mechanisms and Stereocontrol in Complex Organic Reactions

Creator:: Pattawong, Ommidala
Abstract:: Complex organic transformations, such as the addition of pyrrole to ketene using planar chiral organocatalyst (*PPY), the four-component anhydride- Manniach reactions, and the site-selective desymmetrization of meso-1,2-diol, are remarkable synthetic reactions that provide high yield and high selectivity. However, the exact mechanism and origins of stereocontrol for theses synthetic organic...

Expediting the Generation and Analysis of Amorphous Oxide Computational Models: Modeling Complex Systems Swiftly

Creator:: Buchanan, Jacob C.
Abstract:: In this dissertation, the process of computational modeling of amorphous oxide materials is studied. Amorphous oxides have random atomic arrangements with no long-range structural order which makes it difficult to study structure-property relationships. Despite the difficulties, amorphous oxides have great uses as semiconductors and dielectrics in thin-film transistors. The ability...

Galvanostatic control of ion selective electrodes with the solvent polymeric membrane

Creator:: Perera, Hasini R.
Abstract:: Detection technique that proposed utilizing electrochemically controlled, reversible ion extraction into polymeric membrane in an alternating galvanostatic/ potentiostatic mode was introduced. This method is studied in detail to comprehend the advantages of the novel sensor (pulstrode) compared to the potentiometric ion selective electrode (ISE), studies included possible applications and limitations....

Synthesis and oligomerization of y,4-Diamino-2-oxo-1(2H)-pyrimidinepentanoic acid

Creator:: Nelson, Jeffrey Stephen
Abstract:: Described herein is the synthesis of an uncharged stereoregular oligonucleotide analog consisting of cytosine bases linked at specific intervals to a polyamide backbone derived from (L)-glutamic acid. Preparation of this analog entailed borane reduction of (L)- pyroglutamic acid to give optically pure lactam alcohol 9. Tosylation and alkylation with cytosine...
