Solvent Free Vanadium Mediated Organic Transformations, Garrett Oberst
Solvent Free Vanadium Mediated Organic Transformations, Garrett Oberst
Undergraduate Honors Thesis Collection
A mixture of vanadium(V) oxide and copper sulfate was used to catalyze oxidative transformations in a variety of organic compounds. Multiple functionalities were tested, including thiols, amines and alcohols. Various transformations were observed resulting in various oxidized products, including coupling reactions. Reactions were performed in a solvent-free environment due to the insoluble nature of vanadium(V) oxide in common organic solvents. Results were analyzed using HNMR and GCMS.
Chiroptical Ionic Liquids, Benjamin Zercher
Chiroptical Ionic Liquids, Benjamin Zercher
Undergraduate Honors Thesis Collection
The synthesis and fluorescent analysis of chiral light emitting ionic liquids made from lanthanide-doped chiral amino acid ionic liquids is described in this thesis. The ionic liquids were composed of tetrabutylammonium (TBA) cation with enantiomers of the amino acids valine, proline, and aspartate as anionic counterions. These ionic liquids of varying amino acid composition were doped with europium trifluoromethanesulfonate (triflate) and analyzed by circularly polarized luminescence (CPL). The sign of the CPL signal corresponded to the handedness of the amino acids in the ionic liquids. Europium triflate concentration dependent CPL in both [TBA][Val] and [TBA][L-Pro] ionic liquids was measured from …
A Computational And Theoretical Exploration Of The St. Petersburg Paradox, Alexander Olivero
A Computational And Theoretical Exploration Of The St. Petersburg Paradox, Alexander Olivero
Undergraduate Honors Thesis Collection
This thesis displays a sample distribution, generated from both a simulation (for large n) by computer program and explicitly calculated (for smaller n), that is not governed by the Central Limit Theorem and, in fact seems to display chaotic behavior. To our knowledge, the explicit calculation of the sample distribution function is new. This project outlines the results that have found a relation to number theory in a probabilistic game that has perplexed mathematicians for hundreds of years.
Tango: A Spanish-Based Programming Language, Ashley Zegiestowsky
Tango: A Spanish-Based Programming Language, Ashley Zegiestowsky
Undergraduate Honors Thesis Collection
The purpose of this thesis is a two-part project. The first part of the project deals with the creation of my own Spanish-based programming language, Tango, using Spanish key words (instead of English key words). The second part of the project relates to the design and implementation of a compiler that follows the grammar rules outlined in the Tango language in order to successfully lexically analyze, parse, semantically analyze, and generate code for Tango. The structure of this thesis begins with a description of the specific goals achieved in the Tango language, an explanation and brief examples of the Tango …
Substrate Specificity Of The Lipn Hydrolase From Mycobacterium Ulcerans, Stephanie Raynor
Substrate Specificity Of The Lipn Hydrolase From Mycobacterium Ulcerans, Stephanie Raynor
Undergraduate Honors Thesis Collection
Mycobacterium ulcerans is the causative agent of Buruli ulcer, a tropical skin disease that affects thousands of individuals annually. Recent studies have revealed that lipolytic enzymes are involved in the pathogenicity processes of mycobacterium and could be potential targets for novel antibiotics. LipN is one proposed serine hydrolase in Mycobacterium ulcerans that contains the conserved α/β hydrolase protein fold and utilizes the conserved catalytic traid of serine, histidine, and aspartate/glutamate. The physiological substrate and biological role of LipN from M. ulcerans have not yet been determined. In this study, LipN was cloned into a pET28a plasmid and overexpressed in an …
