On February 22, 2016 John Anthony, a ����vlog�ٷ���� professor at the ����vlog�ٷ���� had an article featured in the Nature Communications publication.  The article titled, "Reducing dynamic disorder in small-molecule organic semiconductors by suppressing large-amplitude thermal motions," deals with understanding performance vibrations in organic semiconductors.

All solids are composed of atoms or molecules, and at temperatures above absolute 0 (-460 °F) these molecules are vibrating rapidly.  Such vibrations decrease the performance of semiconductors (critical components in computer chips and modern video displays), because the movement of the molecules can deflect charges moving through the solid.      

Anthony's work with researchers in England and Belgium, investigates the specific nature of these vibrations and their impact on charge being

The editors of the journal Energy Technology named an article by ����vlog�ٷ���� ����vlog�ٷ���� Professor Susan Odom one of the top 10 articles of 2015.  Odom’s publication, "A Highly Soluble Organic Catholyte for Non-Aqueous Redox Flow Batteries," was selected based on the number of downloads and citations, and the feedback of the journal’s editorial office Energy Technology publishes articles covering all technical aspects of energy process engineering from different angles. Due to the selection of Odom’s article, it is accessible for free of charge via the Wiley online library until the end of 2016:

The combined experimental and theoretical effort sought to establish relationships between strain and the work functions of organic semiconductors, important connections for developing fundamental insights into the electrical properties of organic thin films. The results of this study will have broad impact for the development of next generation flexible electronic devices.

UK ����vlog�ٷ���� graduate student Elizabeth Pillar has been selected as a recipient of the 2016 ����vlog�ٷ���� Woman’s Club Fellowship. This fellowship provides $2000 from the ����vlog�ٷ���� Woman’s 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 (����vlog�ٷ����) and Research Scientist Cameron Lippert (CAER) published an article titled “Carbonic Anhydrase Mimics for Enhanced CO2 Absorption in an Amine-based Capture Solvent” in Dalton Transactions, featuring undergraduate alumnus Rachael Kelsey as the first author. Kelsey, now a medical student at the ����vlog�ٷ����, 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 ����vlog�ٷ���� 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–acceptor packing and interfacial (contact) area, and miscibility. The results point to the very significant role that seemingly modest changes in

Assistant Professor of ����vlog�ٷ���� 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 ����vlog�ٷ���� of Materials. The manuscript describes how non-covalent interactions can lead to preferential molecular packing motifs of π-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 21652–21656.

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 Concentrations in Lithium-Ion Batteries."

The study entitled explores the interaction of atmospheric oxidants, such as gaseous ozone and hydroxyl radical, with oxy-aromatic hydrocarbon surfaces under variable relative humidity. The environmental chemistry group found that carboxylic acids and polyhydroxylated biphenyls and terphenyls products can be generated from organic species emitted during combustion processes. The implication of this finding is that heterogeneous reactions provide a channel for the generation of secondary oxidants (hydroxyl radicals, hydroperoxyl radicals, and hydrogen peroxide) during atmospheric processes.

Oftentimes, students find themselves struggling to pick a direction to take once they have received their degree. On October 2, 2015, the ����vlog�ٷ���� Alumni Board helped to answer some common questions students may have about life after graduation during an informal luncheon with the chemistry graduate students. All graduate students were invited to attend and chat with some alumni board representatives about their respective fields and the paths they took to get there. There were four alumni board members in attendance: Peter Nickias ‘87, Amy Wong ‘94, Jeff Lomprey ‘93 and Hugh Huffman ‘72. Together these individuals represented the wide spectrum of options students may choose from upon entering the workforce.

A large portion of the discussion gravitated towards being a post-doc, and if that was necessary and valuable or if a young scientist could be
