DENTON (UNT), Texas — Prateek Kalakuntla of Plano, a student at the University of North Texas’ Texas Academy of Mathematics and Science, has been named a regional finalist in the 2016 Siemens Competition in Math, Science and Technology. In addition, 15 other TAMS students were named semifinalists in this competition, with TAMS leading other Texas schools in the number of semifinalists and having the third largest number of semifinalists in the nation.

Established in 1999 by the Siemens Foundation, the Siemens Competition is one of the nation’s premier research competitions for high school-aged students, promoting excellence in math, science and technology by encouraging students to undertake individual or team research projects.

As a regional finalist, Kalakuntla receives a $1,000 scholarship and will compete with other regional finalists from Texas and nine other states for a spot in the national competition, which will be held Dec. 2-6 at the George Washington University in Washington, D.C.

For his Siemens project, Kalakuntla investigated the use of phosphorescent materials and methods for sensing and removing mercury and other toxic heavy metals from water. He combined gold with a ligand — a molecule that binds to a receptor — to synthesize a substance that usually has a green emission, but has a reduced emission in the presence of mercury.

He has been working on the research in the laboratory of Mohhamad Omary, UNT professor of chemistry and affiliated professor of physics, for almost a year.

“In the beginning, I was looking for sensors to identify molecules, but after the water crisis in Flint, Michigan, I wanted to find something that could sense lead or mercury. I also took a holistic view, because lead and mercury in drinking water is a problem in Third World countries,” Kalakuntla said. He noted that his work with heavy metal sensors “allows me to constantly be on the cusp of discovery.”

“I may find a new ligand that can sense heavy metals. I may find that my ligand is sensitive to materials I had not considered before, or I may find a new application for one of my sensors,” he said. 

Kalakuntla will present his research before judges at the University of Texas Nov. 19. Two winners will be selected to each receive $3,000 and a spot in the national competition. The regional winners will be announced Nov. 21.
