2007 Departmental News
Professor Edward Quitevis received notification that his ACS-PRF Type AC proposal entitled "Understanding the Role of Nanostructural Organization in the Intermolecular Dynamics of Room Temperature Ionic Liquids," was recommended for funding by the ACS PRF Advisory Board for $100,000 for two years starting January 1, 2008. This is the second grant that Professor Quitevis has received this year for his research on the spectroscopy of ionic liquids. Quitevis's research will study how the liquid structures that form on the nanoscale determine the intermolecular dynamics of these materials.
Professor Edward Quitevis was awarded a $454,050 NSF grant over three years, beginning September 1, 2007, for "Probing Nanostructural Organization in Room Temperature Ionic Liquids Using Optical Kerr Effect Spectroscopy". This proposal, which was sent to the highly competitive Experimental Physical Chemistry Program, is aimed at obtaining a fundamental understanding of the intermolecular dynamics of ionic liquids. These materials are of great interest in that they are "green" alternatives to volatile organic compounds (VOCs) used in chemical and industrial applications.
A paper by Assistant Professor Dimitri Pappas was the featured article in the October 2007 issue of Analytica Chimica Acta. The paper, entitled "Isolation and counting of multiple cell types using an affinity separation device," was co-authored by graduate student Kelong Wang and honors college undergraduate Brandon Cometti. The Pappas group also published a review article in the same issue of the journal.
Former Graduate Student Accepts Faculty Position
Dr. Lin Gao, who earned her PhD from this department in December 2006 under Professor Shaorong Liu, has joined The University of Mary Hardin-Baylor as an Assistant Professor.
Edward Quitevis Research Paper Featured as Journal of Physical Chemistry Cover Article
A paper entitled, "Nanostructural Organization and Anion Effects on the Temperature Dependence of the Optical Kerr Effect Spectra of Ionic Liquids", by Professor Edward Quitevis, and his coworkers, was one of 6 articles featured on the cover of The Journal of Physical Chemistry B, Volume 111, No. 18. The paper describes studies of the relationship between the structure and intermolecular dynamics of room temperature ionic liquids (RTILs). RTILs are of great interest in that they are "green" alternatives to volatile organic compounds (VOCs) used in chemical and industrial applications. The Journal of Physical Chemistry B has an ISI impact factor of 4.115, highest among general physical chemistry journals. For more information, choose Article 4 once you click here.
Associate Professor L. William Poirier has recently received an NSF Small Grant for Exploratory Research (SGER) entitled "Bipolar Quantum Trajectory Simulations". SGER applications, submitted only with approval of an NSF program officer, explore "high risk and novel ventures into emerging and potentially transformative research ideas, likely to catalyze rapid and innovative advances." Poirier's SGER project, a two-year grant in the amount of $173,418, will develop numerical methods to incorporate quantum mechanical effects into existing classical simulations codes (already used in a great many scientific and engineering fields), thus allowing reliably accurate quantum calculations to be performed for large systems for the first time.
Robert A. Welch Professor William L. Hase is PI and Yu Zhunag (Department of Computer Science) is co-PI of a Partnership in International Research and Education (PIRE) grant awarded to Texas Tech University by the National Science Foundation.

Associate ProfessorDennis C. Shelly leads the American Leather Chemists Association (ALCA) as it hosts the 29th Congress of the International Union of Leather Technologists and Chemists Societies (IULTCS). Their meeting is scheduled for June 20-24 in Washington, D.C. and will also be the 103rd Annual Meeting for the 400-member American group, over which Shelly presides as President. "This is another way that Texas Tech and the ALCA are working together," said Shelly. Shelly is tireless in promoting the domestic leather industry, and especially that in Texas, as he is director of TTU's Leather Research Institute.

Geneva Peterson (senior, Chemistry) has been awarded a National Science Foundation Graduate Fellowship. She has worked primarily with Drs. Dominick J. Casadonte and Louisa J. Hope-Weeks. Ms. Peterson is a two-year winner of the Goldwater ($7500/year for undergraduates), and she also won the Gates-Cambridge (four years to a Ph.D. at Cambridge University, UK).
Paul Whitfield Horn Professor Richard A. Bartsch presented two papers in the Symposium on Calixarenes: State of the Art and Perspectives on March 26th at the 233rd National Meeting of the American Chemical Society in Chicago. This symposium is organized by the ACS Division of Industrial & Engineering Chemistry.
Associate Professor Robert W. Shaw received $63,000 for his project. He has developed a compound that could increase the effectiveness of current antibiotics. His work is protected by three patent applications. There is a $30 billion market for antibiotics in the United States alone. But bacteria are becoming resistant to traditionally used antibiotics. Disease causing bacteria are producing enzymes that cause a change in the chemical structure of an antibiotic rendering it ineffective in killing the bacteria. Shaw has developed an inhibitor compound which can be administered in combination with antibiotics to prevent the enzymes from inactivating the antibiotic allowing the drugs to kill the bacteria. Shaw will use his grant for animal testing that will accelerate the commercialization of the technology.
Camille Robinson, a junior Biochemistry major, has been selected as a finalist in the Harry S. Truman scholarship competition. This scholarship is for $30,000 toward graduate school for a student intending to pursue a public service career. TTU has only one Scholar and three other finalists on our record. Ms. Robinson will interview for the scholarship on March 13. She already has been admitted to TTU med school. Camille is currently working in Dr. W. David Nes' lab.
Geneva Peterson, a senior Chemistry major, has been awarded a Gates-Cambridge scholarship. She is a two year Goldwater Scholar, as well as recipient of many TTU science scholarships. The Gates is used for study at University of Cambridge (UK) for up to 4 years. It is valued at approximately $160,000. Drs. Brandon Weeks, Gary Elbow, Marjean Purinton, and Dominick J. Casadonte helped prepare Ms. Peterson for the scholarship interview process. Her award is TTU's fourth Gates-Cambridge award (previous winners are Jay Reddy, Michael Henne, Nicholas Johnson).
Graduate student Cynthe Sims will receive 2007 Science: It' A Girl Thing (SIGT) Provost Award. She will also receive a fee waiver.
