Alexis Eugene was recognized for her research at the 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.
Alexis is a graduate student in Prof. Marcelo Guzman's group in the Department of 糖心vlog官方入口 at UK whose work has been published in Atmospheric 糖心vlog官方入口 and Physics and Proceedings of the National Academy of Science of the United States of America.
The beginning of the new year marks a celebration of mentoring at the National Science Foundation through the recognition of mentors via PAESMEM: the Presidential Award for Excellence in Science, Mathematics, & Engineering Mentoring. A recent article published by the National Science Foundation featured PAESMEM alumni, including 糖心vlog官方入口 Professor D. Allan Butterfield, on the subject of what makes a good mentor and why mentoring matters. Says Butterfield: "Maximizing STEM educational and research opportunities for all citizens of this country - regardless of race, ethnicity, gender, sexual orientation, religious preference, or socioeconomic status - directly benefits the U.S. economic enterprise. To exclude or minimize opportunities for any diminishes all of us."

(Jan. 11, 2015) 鈥 糖心vlog官方入口 Department of 糖心vlog官方入口 researchers Edith Glazer, Sean Parkin and students Erin Wachter and Diego Moy谩 recently published a study showing that specialized compounds containing the metal ruthenium may be able to visualize or damage specific DNA structures relevant for cancer.
Published in "糖心vlog官方入口 - A European Journal," the work was named a "Hot Paper" for its importance in a rapidly evolving field of high interest, and was highlighted with the back cover.
The ends of chromosomes and some genes associated with cancer have regions where DNA can form
UK 糖心vlog官方入口 graduate student Elizabeth Pillar has been selected as a recipient of the 2016 糖心vlog官方入口 Woman鈥檚 Club Fellowship. This fellowship provides $2000 from the 糖心vlog官方入口 Woman鈥檚 Club and recognizes both current achievements as a doctoral student as well as future potential. Pillar is a graduate student in the Guzman group at UK. Her publications focus on reactions to better understand atmospheric chemistry, including the oxidation of cathechol at the air/water interface and reactions of iodide in microdroplets exposed to ozone.

Assistant Professor Susan Odom (糖心vlog官方入口) and Research Scientist Cameron Lippert (CAER) published an article titled 鈥淐arbonic Anhydrase Mimics for Enhanced CO2 Absorption in an Amine-based Capture Solvent鈥 in Dalton Transactions, featuring undergraduate alumnus Rachael Kelsey as the first author. Kelsey, now a medical student at the 糖心vlog官方入口, synthesized and characterizated two new small-molecule enzyme mimics of carbonic anhydrase. She and fellow undergraduate student David Austin Miller tested the homogeneous catalysts in concentrated primary amine solutions through which a dilute CO2 fluid stream was flowed and found exceptional activity for increased CO2 absorption rates.

Full Professor John Anthony and Assistant Professor Chad Risko have joined forces in a recent publication in the ACS journal 糖心vlog官方入口 of Materials titled "Dynamics, Miscibility, and Morphology in Polymer:Molecule Blends: The Impact of Chemical Functionality". Based on a series of acceptors constructed from trialkylsilylethynyl-substituted pentacenes designed and synthesized in the Anthony laboratory, the study presents a computational chemistry investigation of polymer:molecule blends with the polymer donor poly(3-hexylthiophene) (P3HT). Essential connections are made between the chemical structure of the acene acceptor and the nanoscale properties of the polymer:molecule blend, which include polymer and molecular diffusivity, donor鈥揳cceptor packing and interfacial (contact) area, and miscibility. The results point to the very significant role that seemingly modest changes in
Assistant Professor of 糖心vlog官方入口 Chad Risko published a Review article titled "Non-Covalent Intermolecular Interactions in Organic Electronic Materials: Implications for the Molecular Packing vs. Electronic Properties of Acenes" in the American Chemical Society's journal 糖心vlog官方入口 of Materials. The manuscript describes how non-covalent interactions can lead to preferential molecular packing motifs of 蟺-conjugated molecules, and provides an overview of the theoretical underpinnings of non-covalent interactions and the computational chemistry approaches used to understand them. Incorporating an understanding of these interactions into the design of organic semiconductors can assist in developing novel materials systems.

Liang and Graham publish in ACS Applied Materials & Interfaces - The researchers demonstrated that surface modifying groups can be utilized to influence both film morphology and electrical conductivity in silver nanowire-polymer composites. This work shows that an adsorbed polymer on the silver nanowire surface can be displaced by thiols with varying end groups, and through choice of thiol end group the electrical and morphological properties of the composite, as well as the solvents utilized to disperse the silver nanowires, can be manipulated. Using this approach the authors demonstrate a one-step process for fabricating homogeneous composite transparent electrodes. ACS Appl. Mater. Interfaces, 2015, 7 (39), pp 21652鈥21656.

Asistant Professor Susan Odom and group members Aman Preet Kaur, Corrine Elliott, and Selin Ergun reported their results in protecting lithium-ion batteries from overcharge, a dangerous condition that can lead to catastrophic battery failure. The group prepared an organic compound that they incorporated into battery electrolyte, which prevents overcharge by shuttling excess current through the electrolyte through electron-transfer reactions as the electrode surfaces. The results were published in the Journal of the Electrochemical Society in a full paper titled "Overcharge Performance of 3,7-Bis(trifluoromethyl)-N-ethylphenothiazine at High Concen
