Posters

Room-temperature stabilization of metastable β-NiMoO4 is achieved through urea-assisted hydrothermal synthesis technique. Structural and morphological studies provided significant insights for the metastable phase. Furthermore, detailed electro- chemical investigations showcased its activity toward energy storage and conversion, yielding intriguing results. Comparison with the stable polymorph, α- NiMoO4, has also been borne out to support the enhanced electrochemical activities of the as-obtained β-NiMoO4. A specific capacitance of ~4188 F/g (at a current density of 5 A/g) has been observed showing its exceptional faradic capacitance. We qualitatively and extensively demonstrate through the analysis of density of states (DOS) obtained from first-principles calculations that, …

Education And Its Effect On The Over Prescription Of Antibiotics, Zackary Goswick

Posters

The purpose of this research is to explore whether providing quality education on antibiotics will, in fact, help limit the number of multidrug resistant organisms (MDROs) infecting the current population. Far too often, antibiotics are prescribed to individuals who do not need them. This overuse causes antibiotics to lose their effectiveness as the human body builds up a tolerance with each subsequent use, thus creating “superbugs.” These are organisms that have become unbeatable with the available antibiotics. Over prescription of antibiotics can happen for a myriad of reasons. One of the biggest being patients (frequently parents of pediatric patients) seeking …

The Populist movement of the late nineteenth century proved a strong presence in states across the Southern and Western United States for a variety of reasons. Burdensome debt, frustration over monopolies, and overall financial decline characterize the core of Populist’s economic grievances, while demands for more direct participation of citizens in politics provide the basis of their political designs. Each state faced its own unique circumstances that Populists were responding to, but these provide a general framework for the movement nationwide. Despite these shared grievances, Populist candidates and parties did not see equal success across the nation. States west of …

Nucleophilic additions to epoxides are an important class of reactions in organic chemistry which have found use in material science, as intermediates, and in the synthesis of biologically important compounds. Many nucleophiles add to epoxides via a SN2 mechanism at the least substituted carbon. However, under acidic conditions addition is at the most substituted carbon via a SN1 mechanism. Included within this class of reactions is the addition of carboxylic acids to epoxides using tetrabutylammonium bromide as the catalyst. These reactions are straight forward and give high yields of the product. However, previous work in our lab using phthalimide as …
