Iberi and Simmons Received ACS Outstanding Poster Award

April 9, 2012 by chemweb

Vighter Iberi and Philip Simmons, two graduate students from Dr. Camden’s Group received American Chemical Society Physical Chemistry Division Outstanding Student Poster Award presented at the 243rd National ACS Meeting in San Diego, CA on March 25.

During the poster session, Simmons and Iberi presented some results of their project aiming to correlate plasmon data obtained from optical microscopy and electron microscopy with theory. “Vighter did the experimental and I did the theory work.” Simmons said.

Iberi and Simmons both described their working experience with each other as fun and rewarding. “Working with DJ (Simmons) has been fun!” Iberi said. “He (Simmons)’s been very helpful in doing all of the complex classical electrodynamics calculations related to our experiments.” Simmons added that while both theory and experiment parts are challenging and call for a tremendous amount of work, “working together we’ve been able to accomplish much more than we would have just working solo.”

They are looking forward to continuing this project. “Work still has to be done in understanding the behavior of electromagnetic hot spots that are responsible for surface-enhanced Raman scattering (SERS) when excited by an electron beam.” Iberi said.

Iberi obtained his B.S. degree from Campbellsville University in 2008 and joined Camden Group in 2009. Now a 3rd year graduate student, Iberi’s research area focuses on the plasmonic studies of nobel metallic nanostructures by using the powerful tools of electron and dark-field optical microscopy. After graduation, Iberi hopes to pursue a career in a research institution such as a National Laboratory or a company with an intellectually stimulating Research and Development division.

Hailed from Buckhannon, West Virginia, Simmons joined the Camden Group in 2011 after obtaining his B.S. from Fairmont State University in 2009. His research involves computational electrodynamics of plasmonic nano-structures and Raman spectroscopy. Although it might still be early to think about career after graduation, Simmons hopes to join the computer hardware industry eventually.

Burton Mandrell and David Cooper, two undergraduate students from Camden Group also attended meeting and presented their research.

Chemistry Undergrad Published in J. Phys. Chem.

February 29, 2012 by chemweb

William Hembree, a chemistry major, published a paper Three-Dimensional Mapping of Microenvironmental Control of Methyl Rotational Barriers last June in the Journal of Physical Chemistry as the first author.

Hembree started working on the project with his mentor Dr. Jerome Baudry, Assistant Professor of the Department of Biochemistry & Cellular and Molecular Biology in the summer of 2008. Baudry was proud of what Hembree was able to achieve.

“…it is rare for an undergraduate to be the first author of a peer-reviewed publication, in particular on a paper of ACS caliber.” Baudry said. On top of that, being one of the two authors means Hembree “did the bulk of the work himself.”

Scientific research is not all about glamorous or exciting moments like some might think. Obtaining data can be a boring process. Baudry pointed out that persistence is what leads to success. “William’s project was challenging…he  was willing and able to put a lot of work in  sometimes tedious tasks and never get discouraged or frustrated.”

Hembree is grateful of what this research experience has given him. “I was fortunate enough to work at Oak Ridge National Labs and the University of Tennessee with many top-level scientists. The knowledge and instruction they gave me has been invaluable in my studies. Above all, I owe many thanks to Dr. Baudry for all his help.” Hembree said.

Undergraduate research is much encouraged in all science fields, especially in a Research I Institute like the University of Tennessee. The students who participate will not only gain research experience, but can also find out if doing scientific research is something they will enjoy for their future career.

“…doing good scientific research means that one must like the “journey” as much (if not more) as the ‘destination'” Baudry said, “…if you wake up every morning hoping to get something unexpected and exciting in the lab, then you are a researcher. If you do that in computational chemistry and computational biology, like William did, then you are a scientific researcher. ”

Hembree is graduating this May with a degree in Chemistry and a degree in German. He is excited to see what future will bring him. “My plans are uncertain after graduation;  I am in the process of applying for a post at the IAEA in Vienna, Austria.  I am considering graduate school as well.”

Note:  Out of 127 journals in the Physical Chemistry category, The Journal of Physical Chemistry B ranks #1 in total citations with 113,180 total cites. The Journal received an Impact Factor of 3.603.*
