A research study led by the University of Kentucky Department of Chemistry has discovered a new way to dramatically boost the performance of electrically conductive polymers. The discovery is considered a significant step forward in the development of organic thermoelectric devices, which can convert waste heat into useful electric energy. 

Conductive polymers, which are electrically conductive plastics, have the potential to transform current electronic devices, such as smart watches, by powering the devices based on the user’s body heat. They are also attractive for converting waste heat from coal-fired power plants or heat from a car’s engine into electricity.

“One day, organic thermoelectrics may be used to power smart watches and other wearable electronics, eliminating the ever pressing need to

Electrically conductive polymers have the potential to transform the form factor of current electronic devices and enable novel applications, such as mechanically flexible and stretchable wearable electronic devices. Conductive polymers could even be incorporated into flexible thermoelectric devices to power these wearable devices based on the user’s body heat. In the paper led by Zhiming Liang of the Graham group entitled “n-type charge transport in heavily p-doped polymers” (available here: https://rdcu.be/cc2C5) the Graham, Risko, Strachan, Mei (Purdue), and Podzorov (Rutgers) groups uncover how the charge-carrier polarity can change in heavily doped π-conjugated polymers to enable both n-type and p-type thermoelectric materials to be made from the same polymer-dopant combination.

Electrical conductivity in conjugated polymers has been researched for decades, in part led

Paul G. Sears, 96, died September 12 in Lexington, KY.

"Paul, a World War II veteran, served in the US Army Air Corps as a tail gunner on a B-17, which was shot down; he was a prisoner of war for 19 months. After the war, he completed his degrees and performed research for 2 years at Monsanto. He then joined the University of Kentucky faculty and became widely recognized for his research on nonaqueous solvents. He taught at all levels, influencing the lives of more than 7,000 students, and received several great-teacher awards. He was inducted into the College of Arts & Sciences Hall of Fame in 2013 and was the faculty representative on the board of trustees for 9 years."

When it comes to portable electronic devices, such as cell phones, laptops, tablets or smart watches, how often do we feel frustrated because the battery is about to die, or because it doesn’t last as long as it did a few months ago?

Chad Risko, an associate professor of chemistry and affiliated faculty researcher at the Center for Applied Energy Research at the University of Kentucky, says this simple context shows the value in creating better batteries. But it is not just small portable electronics that need more robust, and differentiated, energy storage.

“Electric and hybrid vehicles are becoming more omnipresent, and here we need batteries that are lighter in weight, safer and can store ever more energy,” Risko said. “Further, as our nation’s energy

The UK Department of Chemistry and the UK Office for Institutional Diversity have arranged to make the film, Picture a Scientist, available for anyone in the University of Kentucky community to view.

“PICTURE A SCIENTIST chronicles the groundswell of researchers who are writing a new chapter for women scientists. Biologist Nancy Hopkins, chemist Raychelle Burks, and geologist Jane Willenbring lead viewers on a journey deep into their own experiences in the sciences, ranging from brutal harassment to years of subtle slights. Along the way, from cramped laboratories to spectacular field stations, we encounter scientific luminaries - including social scientists, neuroscientists, and psychologists - who provide new perspectives on how to make science itself more diverse, equitable, and open to all.”

LEXINGTON, Ky. (Sept. 30, 2020) — Instructors in the College of Arts and Sciences at the University of Kentucky are combining technology, learning techniques honed by experience, and human interaction to provide multifaceted learning environments for their students.

The goal, as always, is to keep students engaged with hands-on instruction methods even if the current pandemic limits face-to-face class time.

“Students learn by working on problems, not just by listening,” said Alberto Corso, associate professor and director of undergraduate studies in the Department of Mathematics. “That’s what I tell all of my students. We all like to watch our favorite basketball teams play, but we can’t play with them unless we practice. We need to be on the court and practice

The National Science Foundation has awarded a new grant to Drs. David Heidary and Edith Glazer for the development of chemical tools to study RNA. The project, titled “Inorganic-aptamer hybrids for live cell imaging”, leverages the complementary expertise of the investigators in the development of optical cellular assays and the creation of photoactive inorganic molecules.

RNAs are functionally and structurally diverse molecules that play a role in the encoding, transmission, and regulation of genetic information, as well as catalysis. The ability to accurately track and quantify RNA levels or localization, either on the subcellular or tissue levels, is important to understanding the role of RNA in the regulation of biological processes. Given the dynamic nature of RNA, the information should be obtained in real time and in living cells. However, there are currently no

My dad, Charles Herschel Holmes Griffith, was a devoted son, Marine, husband, father of two, grandfather of four, chemist and teacher. He gave his full devotion to the things he loved most – his family and education. Dad always said teaching Chemistry at UK was his “dream job” and from 1964-1991 he loved every minute of working with students and supervising TA’s in his General Chemistry labs. At his funeral in 2013, the Chair of the department told me that my dad undoubtedly had more direct contact with UK college students than anyone else in the history of UK’s Chemistry department.

As I was putting together Dad’s biography in 2011, I found this in a letter he wrote - “I was born in Huntington, IN into a family of educators.” Both of his parents were college graduates, each with a Bachelor’s and Master’s degree. His mom was an English teacher

The College of Arts and Sciences is committed to learning and working environments that are diverse, inclusive, and equitable for students, staff, and faculty.

We stand in solidarity with those working to confront systemic racial injustice in our communities and in the United States. We recognize the disproportionate burden of racism and other forms of violence on many within our A&S community during this time. We affirm our support of faculty, students, staff, and alumni in standing against all forms of racism, discrimination, and bias.

During this time of pandemic and continued racism and violence that especially impact marginalized communities of color, we recognize the disproportionate impact on Black and African-American people. In the context of the deaths of Ahmaud Arbery, George Floyd, and here in Kentucky, Breonna Taylor and David McAtee, we affirm that

LEXINGTON, Ky. (May 21, 2020) — Transportation is the world's largest source of greenhouse gas emissions. Automakers  are challenged to meet higher standards designed to reduce vehic,le pollution. This pollution contributes to climate change and can be detrimental to human health.

Adhering to the new standards requires removing pollutants, specifically poisonous and highly reactive nitrogen oxides (NOx) from exhaust gas when a vehicle is started and the gas is still cold. The device that does this removal  — a catalytic converter — needs to be warm to efficiently remove NOx, however.
