Novel “Acid Tuned” Deep Eutectic Solvents Based On Protonated L-Proline, Patrycja Janicka, Andrzej Przyjazny, Grzegorz Boczkaj

Natural Sciences Publications

The paper presents new types of deep eutectic solvents (DESs) based on L-proline protonated using three different acids (hydrochloric, sulfuric and phosphoric)and playing the role of a hydrogen bond acceptor(HBA). Glucose and xylitol were used as hydrogen bond donors (HBD). A series of deep eutectic solvents with various mole ratios were obtained for the systems L-proline: glucose and L-proline: xylitol. Density, melting point, pH and viscosity of the synthesized DESs were determined along with the effect of water content, mole fraction of the HBA in DES and temperature on properties of the DESs. A wide range of densities (1343–1606 kg/m3), …

Exploration Of Fluorinated Α,Β-Dehydroamino Acids And Their Structure, Austin Lesueur

Undergraduate Honors Theses

This thesis explores the synthesis of fluorinated α,β-dehydroamino acids, specifically a fluorinated dehydrovaline derivative. Previous work has been done on the equivalent dehydrovaline derivative without fluorine present and this work builds toward the fluorinated version with the goal of comparing the two structurally. The synthesis presented here pulls from previous synthetic strategies employed for dehydrovaline while also exploring the synthetic impact of the electronegative fluorine atoms.

Investigations Involving Mononuclear And Dinuclear Transition Metal Catalysts For Photochemical Carbon Dioxide Reduction, Ansu Edwards

Honors Theses

There is currently a global energy crisis, which is in desperate need of solutions. New energy sources are required that will not pollute as much as our longstanding reliance on nonrenewable fossil fuels as an energy source. This pollution involves large amounts of greenhouse gas emissions, predominantly carbon dioxide (CO₂), that contribute to environmental problems such as climate change. In this context, a fairly recent research direction to address this problem is the development of transition metal catalysts that can convert CO₂ into reduced carbon products that can serve as chemical fuels. This work focuses on the …

Synthetic Pathways For Potential Platinum 1,10-Phenanthroline Compounds, Jacob Young

Mahurin Honors College Capstone Experience/Thesis Projects

There are extremely important uses for platinum when it comes to the treatment of cancers and dementias. One potential therapeutic combines platinum with a structure known as phenanthroline. This platinum phenanthroline structure is normally extremely water-insoluble, rendering it difficult to study and use in biological systems. The Williams’ Biochemistry Laboratory endeavored to find a simpler synthetic pathway for a water-soluble phenanthroline product. While unsuccessful in identifying a product as of yet, many synthetic pathways have been ruled out, and more hypothetical pathways are being formulated for testing.

Among the strategies analyzed are varying solvent, reagents, apparatus, methodology, and temperature in …
