Chemistry Department Hosts 2019 SETCA Meeting

May 30, 2019 by Kayla Benson

The theoretical and computational division of the Department of Chemistry hosted the 2019 SETCA (Southeastern Theoretical Chemistry Association) meeting this spring at the University of Tennessee, Knoxville.

The Southeastern Theoretical Chemistry Association (SETCA) is a loose organization of theoretical and computational chemists from across the Southeastern United States. Since its inception in 1970 by Prof. Bruno Linder of Florida State University, its primary function has been an annual conference to give faculty, students, and postdoctoral associates an opportunity to present their most recent research results.

SETCA has a longstanding tradition of excellence in bringing together these communities to address the widespread challenges of computational chemists.

The meeting included a Scientific Programming Workshop, designed for undergraduate research students, conducted by MolSSI, two poster sessions, 12 invited speakers, and a dinner banquet with keynote speaker Weitao Yang.

Congratulations to the six SETCA 2019 Poster Winners!

  • The Quest for a Local Representation of Virtual Spaces for Embedded Wave Functions, Daniel Claudino, Virginia Tech
  • Computational Studies on Substrate Binding Motifs in Dissimilatory Sulfite Reductase, Alexa Griffith, Oak Ridge National Laboratory

Musfeldt Former Postdoc wins NSF CAREER Award

May 24, 2019 by Kayla Benson

Former postdoc, Dipanjan Mazumdar, worked with the Musfeldt group for two years from 2012-2014. He now has a tenure-track job at Southern Illinois University Carbondale and is a 2019 NSF CAREER Award recipient for his work with thermal stability and scaling of nanoscale spin-electronic devices based on novel inverse-Heusler alloys.

“When I started my research career, I learned that one can combine ultrathin layers (nanoscale) of magnetic materials to act as a switch utilizing a subtle quantum physics effect called quantum tunneling,” Mazumdar said. “Essentially, in the classical world when we throw a ball onto a wall, it will always bounce back. Always. In the quantum world, however, there is a small chance that throwing quantum objects such as an electron onto a barrier (wall), the electron will end up on the other side of the barrier.”

Maumdar’s goal of this project is to make faster, smaller, energy-efficient magnetic nanoswitches. 

“Surviving in academia is very difficult. Jan Musfeldt helped my career to stay afloat during a very difficult time,” Mazumdar admits. “So this award (and any award/grant I receive in the future) is always going to be directly or indirectly related to the support I received from her at The University of Tennessee, Knoxville, Department of Chemistry.”

Moseley and Sabury Recognized at Chancellor’s Honors Banquet

May 3, 2019 by Kayla Benson

The Chancellor’s Honors Banquet is held each spring to recognize students, faculty, staff and friends of the University of Tennessee for their extraordinary achievements. Extraordinary Professional Promise honors are awarded to undergraduate and graduate students who demonstrate professional promise in teaching, research or other contributions.

Duncan Moseley, a Graduate student of the Xue lab, and Sina Sabury , a graduate student of the Kilbey lab, are shining examples of excellence in our graduate program.

Moseley says, “I am extremely grateful to receive this award from the university, and even more grateful to Dr. Xue for all of his hard work to make me a better researcher and chemist.” Sabury also shares his gratitude, “I am blessed to to receive this honor and I appreciate the efforts from the University for this recognition. “

Xue Group Published and Front Cover in EurJIC

May 2, 2019 by Kayla Benson

The Xue group is excited to announce that their paper “Probing Magnetic Excitations in CoII Single‐Molecule Magnets by Inelastic Neutron Scattering” was published and was selected as the front cover art in the European Journal of Inorganic Chemistry.

This research explores how single-molecule magnets (SMMs) and qubits are of intense current interest for their potential applications as new generation of data storage materials and quantum computing. Graduate student, Duncan Moseley, explains, “The cobalt compound studied here shows SMM properties. Direct observation of magnetic transitions in SMMs and spectroscopic characterization of phonons (molecular and lattice vibrations) in SMMs are challenging.”

The work shows that Inelastic Neutron Scattering (INS) is a method to probe magnetic transitions in SMMs. Xue’s group, through collaboration with scientists at several institutions, including Spallation Neutron Source (SNS) at ORNL, NIST Center for Neutron Research (NCNR) and Max Planck Institutes in Germany, investigated two magnetic transitions in the Co SMM.

Their recent work in Nature Communications using Raman and far-IR showed spin-phonon/vibration couplings in the compound. However, INS spectra here unambiguously reveal the magnetic transitions. Phonon calculations in the work help provide a complete picture of how this cobalt-based SMM behaves.

Dai Group Published and Front Cover in ChemSusChem

May 2, 2019 by Kayla Benson

The Dai lab just published an article in ChemSusChem and the article was featured on the front cover of the journal.

Their research investigates how lithium ion batteries (LIBs) dominate the market for portable electronic devices, limited energy and power density of LIBs offered by conventional electrodes hindered their application for electric vehicles. In order to offer a viable solution to this problem, the group has developed a direct fluorination method to form highly pure oxyfluoride electrode materials that have better electrochemical performances.

With this idea, a novel approach for converting 2D Mxene to 2D TiOF2 with enhanced electrochemical stability and energy density via direct fluorination using elemental fluorine is reported for the first time. 2D TiOF2 offers increased capacity, rate capability and long cycling stability due to its unique layered structure comparing to conventional TiOF2. 

Graduate research assistant, Bishnu Thapaliya, explains, “In this work, we demonstrated that direct fluorination of Mxene results a hybrid metal-carbon oxyfluoride with enhanced electrochemical performance compared to traditional oxyfluoride. Therefore, we believe this novel approach opens a new avenue for the development of many 2D hybrid metal-carbon oxyfluoride materials that can be applied to broader materials research.”

Vogt Memorial

May 1, 2019 by Kayla Benson

Frank VogtThe Department of Chemistry is hosting a morning dedicated to the memory of longtime faculty member Frank Vogt.

First, due to Frank’s dedication to research, we felt it would be appropriate to honor this by holding a special seminar on the day of the Memorial. Professor Jean-Francois Masson from the Universite de Montreal has generously agreed to give this research talk. Masson is a world leader in Frank’s field of Bioanalytical Chemistry and a close colleague of Frank’s. Details for the seminar are listed below:

Time: Friday, May 24th at 10 AM
Location: UT Buehler Chemistry Building room 415
Title: Plasmonic nanobiosensors: From therapeutic drug and environmental monitoring to optophysiology of living cells http://www.sprbiosensors.com/

The memorial will take place at 2 PM that day in the new student union room 169 at the University of Tennessee, Knoxville. If you would like to share pictures of Frank Vogt please email our recruiting and outreach coordinator Kayla Benson (Kayla@utk.edu). Anyone who would like to speak at the Memorial can contact Michael Best (mdbest@utk.edu).

We hope that you will be able to join us to celebrate Frank’s life, career and contributions to Chemistry and the University of Tennessee.
