At a quick glance, one might not think Dave Eaton and Todd Prater would have a whole lot in common.

Eaton, an Owensboro, Kentucky, native who earned his doctoral degree in chemistry from the University of Kentucky Department of Chemistry, is the consummate, professional researcher. Carbon is his game, and the UK Center for Applied Energy Research’s (CAER)laboratories is his home away from home. Whether he is working on carbon fiber, carbon nanotubes, activated carbon or energy storage applications, Eaton is constantly pushing the boundaries of discovery.

LEXINGTON, Ky.​ (Aug.3, 2018) — Could unmanned aircraft systems (UAS), otherwise known as drones, revolutionize weather forecasting? The University of Kentucky continues to conduct groundbreaking research that suggests they could. 

In 2015, a four-university interdisciplinary team began developing small, affordable UAS to measure wind turbulence, atmospheric chemistry, soil moisture and thermodynamic parameters to better understand severe storm formation. The project, known as CLOUD-MAP for "Collaboration Leading Operational UAS Development for Meteorology and Atmospheric Physics," was awarded through the National Science Foundation (NSF) Established Program to Stimulate Competitive Research (EPSCoR

Lexington, KY, (July 25, 2018) — Atmospheric particles with high water content also known as aerosol droplets are widely found on Earth and play a significant role in the planetary chemistry and meteorology. These particles are generally produced in relatively clean air after emissions of gases that nucleate and condense. Many times this process is dominated by organic acids that have been observed in heavily polluted cities. A challenging matter that has recently attracted the interest of many experts is the unknown mechanism by which organic carboxylic acids dissolve from the gas phase into such aqueous particles. In the new work by Prof. Marcelo Guzman and his students Alexis Eugene and Elizabeth Pillar at the University of Kentucky in collaboration with A.J. Colussi from Caltech, micrometer-sized droplets were used to show that acetic acid and pyruvic acid behave as

Postdoctoral scholar Dr. Dmytro Havrylyuk received an award for the poster “Ru(II) CYP1B1 Inhibitor Prodrugs with Enhanced Potency” at the 2018 Metals in Medicine, Gordon Research Conference. The project was performed in collaboration with Kimberly Stevens and Catherine A. Denning in the laboratories of Dr. David K. Heidary and Prof. Edith C. Glazer

Dr. Havrylyuk described the development of highly potent and selective inhibitors of Cytochrome P450 1B1 (CYP1B1), an enzyme that is involved in cancer initiation, progression, and resistance to treatment. CYP1B1 is overexpressed in a wide variety of human tumors, giving it the title of “universal tumor antigen”. The enzyme catalyzes the 4-hydroxylation of 17β-estradiol to form a 3,4-quinone, which reacts with DNA, inducing mutation. CYP1B1 is also implicated in cancer

Congratulations to Alysia Kohlbrand who received a Summer Undergraduate Research Fellowship from UK’s Chellgren Center. This award will support Alysia to work with Drs. Edith (Phoebe) Glazer and David Heidary in the Chemistry Department, to study the effects of small molecule inhibitors on Nitric Oxide Synthase. These enzymes are used in the body to catalyze the production of nitric oxide (NO), an important signaling molecule which plays a central role in human biology. Using engineered cell lines containing fluorescent tags, Kohlbrand will study the half life of NOS in the presence of inhibitors using live cell confocal microscopy, which is particularly useful for this study because it allows for images to be taken over a long period of time without killing the cells, and creating clear, detailed images.

This article is part of a series of articles on “UK Chemistry Alumni: Where Are They Now?”  Here we feature former undergraduate Steven Chapman, class of 2016, who is now a graduate student at the University of Wisconsin, Madison. Steven's research at UW focuses on improving methodology in photocatalysis for asymmetric synthesis. Here Steven answers some questions about his current research, experiences at UK, and provides some advice for current undergraduates.

Could you tell us about your research project at the University of Wisconsin?

The focus of our lab is the development of photocatalytic methodology for asymmetric synthesis using visible light. Photochemical synthetic methods provide a complementary approach to traditional methods because the substrate’s primary reactivity occurs from its excited state rather than its ground state. My project

When an athlete takes a hard hit or fall, one of the first things that comes to the minds of coaches, athletic trainers, team physicians and spectators is the risk of concussion. Protocols are in place to assess if an athlete has sustained a concussion or if they can be cleared to go back into the game. However, there is some ambiguity between physicians as to what constitutes a concussion.

That's why over the next three years and with a nearly $1 million grant from the National Institute of Neurological Disorders and Stroke, researchers at the University of Kentucky are studying whether a rapid blood test could serve as another means of support in diagnosing concussion.

This May we celebrate and recognize the career of Professor Dennis Clouthier, who is retiring from UK after over thirty years of teaching, research, and service to our university community. While it is impossible to quantify Clouthier’s impact on academic and scientific communities, here an attempt is made to highlight some of his most notable accomplishments.  

Clouthier is well known for his pioneering work in molecular spectroscopy, using high-powered lasers to examine reactive intermediates that are particularly difficult to study. His pioneering work has led to the development of new laboratory methods, such as pyrolysis jet spectroscopy, and has significant implications for fields as diverse as understanding the fabric of the cosmos and reducing computer chip impurities.

As a teenager, Clouthier dreamed of making a career out of doing laser light shows for rock

Chad Risko, an assistant professor of chemistryin the University of Kentucky College of Arts and Sciences, didn’t always know there was a career to be had in doing research – until a mentor encouraged him to study chemistry as an undergraduate.

“From there, and when I went to graduate school, is where I think the research bug really took hold,” Risko said. “Being in the lab, working with people, trying to understand new ways to solve problems – that really motivated me to pursue a career in research.”

Now, as a chemistry professor and affiliated researcher in UK’s Center for Applied Energy Research (CAER), Risko says mentoring students

Recently, the UK Chemistry community was saddened to learn of the death of Bob Guthrie, Professor Emeritus and former Chairman of the Department of Chemistry. Bob was born on June 27, 1936 in Bronxville, New York, and after his family relocated, he grew up and received his early education in New Orleans. He knew from a very early age that he wanted to achieve significant goals in his life.

Following graduation from high school, Bob matriculated at Oberlin College and was awarded a Bachelor of Science degree in 1958. While at Oberlin, he began serious study of chemistry under the tutelage of famed chemical educator J. Arthur Campbell. Bob’s next stop on the road to success was the University of Rochester, where he earned his Ph.D. in organic chemistry in 1962 with Marshall Gates, renowned for the first synthesis of morphine.

Do undergraduates make critical contributions to cutting-edge research? The answer is a decidedly yes, and not in small numbers.  Professor D. Allan Butterfield has matriculated more than 160 undergraduates in his laboratory over the 43 years he has been at UK.  Nearly all of these undergraduate researchers performed independent research under the aegis of CHE 395, “Independent Research in Chemistry.”  Approximately 60-plus refereed scientific papers have resulted from the work of these undergraduates [nearly 10 percent of Prof. Butterfield’s total publications (H-index = 96)].  This current spring 2018 semester, four CHE 395 students are in Prof. Butterfield’s laboratory.  The following is a brief synopsis of their research, their thoughts about their education at UK, and their future plans.
