Corrine Elliott receives a Summer Undergraduate Research Fellowship from the Organic Division of the American Chemical Society

Corrine "Nina" Elliott, an undergraduate student majoring in chemistry and mathematics at UK, is the receipient of a Summer Undergraduate Research Fellowship (SURF) from the American Chemical Soceity's Division of Organic Chemistry.  This $5,000 fellowship will allow Corrine to continue research in the Chemistry Department at the University of Kentucky for the Summer of 2016.

Yang group reports a Metal-Activated Oligomerization of Acetylene to Naphthalene Using Supersonic Molecular Beams

Since the discovery of nickel-catalyzed cyclization of acetylene to benzene and cyclooctatetraene, transition-metal-activated cycloaddition of alkynes has become a powerful technique to construct ring compounds in organic synthesis. Although cyclo-trimerization and -tetramerization were discovered almost 70 years ago, direct metal-mediated acetylene oligomerization to polycyclic compounds has not been reported. Instead, cycloaddition of different alkynes, or alkynes with alkenes or arynes, has been used to synthesize polycyclic and other complex ring structures.

Alexis Eugene recognized for research at TFISE Forum

Alexis Eugene was recognized for her research at the 5th Annual Tracy Farmer Institute for Sustainaility and the Environment (TFISE) Forum held in December 2015.  Her poster presentation titled "Photochemistry of alpha-keto acids in model atmospheric waters" received recognition as one of the two best graduate student posters.

Bio-inspired Materials for Carbon Capture and Self-Improvement

Nature uses microvascular structures as a central element of complex materials that grow, regenerate, and improve themselves and their function. Work into synthesizing microvascular materials has recently taken a step forward in the form of a new synthetic process VaSC (Vaporization of a Sacrificial Component) that enables the formation of 3D microstructures that are meters in length. I report on our recent advances in using VaSC to create three-dimensional gas exchange units modeled on the design of avian lungs. I will focus on mass transfer applications for the capture of CO2. I will also report on recent research into creating high surface area micro-structures, the synthesis of cooperative binders of CO2 and chemical reactions mediated by photo-thermal effects. Finally, I will talk about adapting microvascular structure to allow them to improve their functions through chemical remodeling.

The Design, Synthesis, and Characterization of Electron-Donating Phenothiazines for Electrochemical Energy Storage Applications

"Electron-Donating Phenothiazines for Energy Storage Applications"

Prof. Susan A. Odom

Department of Chemistry, University of Kentucky

Phenothiazine derivatives have seen widespread use as stable electron-donating organic compounds with generally stable oxidized states, which makes them an attractive core for functionalization for use in electrochemical energy storage applications. With phenothiazine itself as a starting material, functionalization of the 3, 7, and 10 positions is facile, providing options to modify redox potentials and improve stability in both the neutral and singly oxidized (radical cation) states. Additionally, this ring system can be built from aryl amines and aryl bromides, allowing for the production of compounds with even more functionalization, including incorporating groups at the 1 and 9 positions and – in some cases – at every sp2-hybridized C atom in the aromatic core. In many cases, computational studies have predicted what we have observed experimentally, and often guides our design of next-generation materials. This presentation focuses on the characterization of phenothiazine derivatives, both from experimental and computational approaches, and includes results from their incorporation into lithium-ion batteries as electrolyte additives for overcharge protection as well as studies toward using them in non-aqueous redox flow batteries as catholytes. 

This seminar is part of the 2015-16 Energy Storage Seminar Series at UK supported by NSF EPSCoR under Award No. 1355438.
