Seventeen research students from Oak Ridge High School competed in the 64th Annual Southern Appalachian Science and Engineering Fair hosted at the University of Tennessee. The competition was held April 4-7 with the awards ceremony on Thursday evening. There were 52 Senior Division projects in competition.

All 17 students are a part of either the Experimental Scientific Research, or ESR, course or Math, Science, and Computer Science Thesis course at ORHS. The ESR course is led by Sharon Thomas and Thesis is led by Tammy Carneim and Jessica Williams.

Gabe Vacaliuc earned first place for his project titled “dQCuts: Simplifying Molecular Dynamics Datasets Using Higher Order Statistical Signatures” under the mentorship of Arvind Ramanathan at Oak Ridge National Laboratory. Along with a $1,000 scholarship and trophy, Vacaliuc will travel to Phoenix, Arizona, in May to compete at the International Science and Engineering Fair.

“SASEF was a great experience because I was able to get substantial feedback in a professional setting,” Vacaliuc said. “I’m so grateful to SASEF for the opportunity to represent my school at ISEF in May.” [Read more…]

Novel ORNL technique enables air-stable water droplet networks

A simple new technique to form interlocking beads of water in ambient conditions could prove valuable for applications in biological sensing, membrane research, and harvesting water from fog.

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have developed a method to create air-stable water droplet networks known as droplet interface bilayers. These interconnected water droplets have many roles in biological research because their interfaces simulate cell membranes. Cumbersome fabrication methods, however, have limited their use.

“The way they’ve been made since their inception is that two water droplets are formed in an oil bath then brought together while they’re submerged in oil,” said ORNL’s Pat Collier, who led the team’s study published in the Proceedings of the National Academy of Sciences. “Otherwise they would just pop like soap bubbles.”

Instead of injecting water droplets into an oil bath, the ORNL research team experimented with placing the droplets on a superhydrophobic surface infused with a coating of oil. The droplets aligned side by side without merging. [Read more…]
