Physics lecturer Nilakshi Veerabathina, fourth from left, and a team from UT Arlington made a series of presentations for students at the 7th Annual Aviation and Transportation Career Expo.

     A team from UT Arlington led by physics lecturer Nilakshi Veerabathina helped make physics fun as well as educational at the 7th Annual Aviation and Transportation Career Expo on Dec. 10. The event, hosted by D/FW Airport, the Federal Aviation Administration and American Airlines, was attended by 4,100 K-12 students and over 1,000 teachers and administrators from schools around North Texas. The attendees learned about aviation, transportation and science in general through a series of fun demonstrations.
     UT Arlington's team included undergraduate students Nelson Cardenas and Dondre Rose from the UTA chapter of the International Society for Optics and Photonics (SPIE), and Robert Allen, Aaron Baka, Robert Bruntz, Sophia Cockrell, Jimmy Corbin, Chris Limon, Robert Lord and Elijah Murphy from the UTA chapter of the Society of Physics Students (SPS).
     Physics demonstrations included use of liquid nitrogen; mechanical electrical generators to create spark discharges and mild shocks; wheels and rotating stools for moment of inertia; hand-made spectroscope, various assemblies of mirrors and lenses, big soap bubbles, and optics apparatus to explain the properties and uses of light.

Hurdle's research on treating persistent bacterial infections published in microbiology journal
     
Julian Hurdle
Hurdle
Biology assistant professor Julian Hurdle led four-member research team whose work, "Targeting bacterial membrane function: an underexploited mechanism for treating persistent infections", has been published in the January edition of the journal Nature Reviews Microbiology.
     The review discusses "the emerging concept that disrupting the bacterial membrane bilayer or proteins that are integral to membrane function (including membrane potential and energy metabolism) in dormant bacteria is a strategy for treating persistent infections. ... Despite some drawbacks, membrane-active agents form an important new means of eradicating recalcitrant, non-growing bacteria."

Jim Grover
Grover

     Biology professor James Grover delivered a plenary lecture on Dec. 17 at the International Workshop on Partial Differential Equations Models in Biology, at the National Center for Theoretical Science, National Tsing-Hua University in Hsinchu, Taiwan.
     The lecture was titled, "Resource storage and competition in variable environments: Lagrangian computational approaches and reaction-diffusion approximations."
     Grover has done extensive research in the ecology and physiology of algae and other aquatic micro-organisms. He specializes in the study of water quality in rivers, lakes and reservoirs; theoretical ecology; algal ecology; and biodiversity.

Melotto Obulareddy
Assistant professor of biology Maeli Melotto and collaborator Sheng Hang He of Michigan State University have been awarded an ARRA research supplement in the amount of $252,664 to supplement their $1.85 million National Institutes of Health grant titled "Stomate- based innate immunity against bacterial infection in Arabidopsis."
     For more about Melotto's research, see her lab webpage here.
     Nisita Obulareddy, a graduate student researcher in Melotto's lab, was selected to make an oral presentation of her research in August at the National Annual Meeting of the American Phytopathological Society held in Charlotte, N.C. The abstract of her presentation, "Towards understanding coronatinedependent suppression of Arabidopsis innate immunity," was published in the society journal.

Crystal Cooper
Cooper
     Crystal Cooper, a Ph.D. student in the Health Psychology and Neuroscience program of the Department of Psychology, won an award for her poster presentation on Nov. 4 at the 2010 Greater Dallas Human Brain Imaging Retreat. Posters were judged based on quality of research, clarity of presentation, and aesthetics. Cooper's poster was titled "Successful recollection of names involves a network of brain regions including the left hippocampus and left inferior parietal lobe."
     Cooper received a bachelor's degree in Psychology in 2007 and a master's in Health Psychology and Neuroscience in 2009, both from UT Arlington. Assistant professor of psychology Tim Odegard is her faculty advisor.

A paper by Sharma and Alfonso Hinojosa, "Effects of gold nanoparticles on electro-optical properties of a polymer-dispersed liquid crystal", was published in volume 97 of the journal Applied Physics Letters (2010).
A review by Sharma, "A review of the electro-optical properties and their modification by radiation in polymer-dispersed liquid crystals and thin films containing CdSe/ZnS quantum dots", was published in volume 168 of the journal Materials Science and Engineering B (2010).
A paper by Sharma and R.A. Ramsey, "Effects of gamma radiation on the dielectric and electro-optical properties of a polymer-dispersed liquid crystal", was published in volume 405 of the journal Physica B (2010).
Sharma presented an invited colloquium, "Nanoparticles-induced changes in the electro- optical properties of certain liquid crystal", at Texas A&M-Commerce in September 2010.
Sharma and Chakraborty have submitted a paper for publication, "Evidence for hexagonal diamond nanoparticles in samples grown by chemical vapor deposition".
Sharma's students made two presentations at the March 2010 national meeting of the American Physical Society (APS) in Portland, Ore.: "A study of the structural, optical and electronic properties of diamond nanoparticles" (Chakraborty, LaRoque, Sharma) and "Effects of gold nanoparticles on the electro-optical properties of a polymer-dispersed liquid crystal" (Cecil Shive, Hinojosa, Sharma).
Sharma's students made two presentations at the Fall 2010 Texas Section of the APS (TSAPS) meeting in San Antonio: "Possible mechanisms behind recently observed effects of incorporating gold nanoparticles into a polymer-dispersed liquid crystal" (Hinojosa, Sharma) and "Evidence for hexagonal diamond in CVD grown diamond thin films" (Chakraborty, Sharma).
Chakraborty, a Materials Science and Engineering student, recently completed his M.S. thesis, "A study of diamond nanoparticles", under Sharma's supervision.
Chakraborty and LaRoque received an award for best poster presentation at the Fall 2009 TSAPS meeting in San Marcos for their project, "Chemical vapor deposition of nanodiamonds and study of their structural, optical and electronic properties".
As then-chair of the executive committee of the TSAPS, Sharma presented the group's first Distinguished Service Awards to three members, including retired UT Arlington professor of physics L.M. Diana, at the TSAPS Fall 2009 meeting in San Marcos.
