UT Network Infrastructure to Upgrade to 100G

The UT–Oak Ridge National Laboratory Joint Institute for Computational Sciences—and UT’s Office of Information Technology—have announced final plans to upgrade the bandwidth of UT’s wide area network for research and education to 100 gigabit per second (100G) capability by July 2014. This project makes UT an early adopter of the technology and will improve a wide range of big data and other science data flows.

UT Names Nuclear Materials Expert as Governor’s Chair

Steve Zinkle, an authority on the effect of radiation on materials in fission and fusion nuclear reactors, has been named the thirteenth University of Tennessee-Oak Ridge National Laboratory Governor’s Chair. Zinkle will serve as Governor’s Chair for Nuclear Materials, based in the department of nuclear engineering at UT with a complementary appointment in materials science and engineering. He begins at UT on October 1.

Nazarewicz Named UT-Battelle Corporate Fellow

Witold Nazarewicz, James McConnell Distinguished Professor of Physics, has been selected as a 2013 UT-Battelle Corporate Fellow. The rank of corporate fellow –among Oak Ridge National Laboratory’s highest honors—recognizes the researchers’ significant accomplishments and continuing leadership in their scientific, engineering and technological fields.

Solar Nanotechnology Expert Named as Governor’s Chair

Ramamoorthy Ramesh, an authority in the physics of functional materials, has been named the twelfth University of Tennessee–Oak Ridge National Laboratory Governor’s Chair. He has also been appointed as deputy director for science and technology at ORNL.

New Book Chronicles UT-Battelle’s First Decade of Management at ORNL

UT made a bold move in 1999 when it went public with plans to compete for the management contract of the Department of Energy’s Oak Ridge National Laboratory. In a partnership with Battelle Memorial Institute, a global research and development organization committed to science and technology, the university presented the department with a groundbreaking proposal and assumed responsibility for the lab in April 2000. A new book, “Breaking the Mold,” is the story of the UT-ORNL partnership’s transformational past 13 years and a glimpse of what’s to come.

Supercomputer Research Enhances Energy Model Accuracy

Imagine a world in which an energy model can attain cost savings, security, and sustainability in our buildings. It is the goal of Oak Ridge National Laboratory researchers working on a project using UT’s Nautilus supercomputer. Called the Autotune methodology, the project is playing an important role in placing the bargain of energy efficiency within reach for more commercial and residential buildings. Current energy model exist but lack accuracy.

Scientists Solve Mercury Mystery

By identifying two genes required for transforming inorganic into organic mercury, which is far more toxic, UT and Oak Ridge National Laboratory (ORNL) scientists today have taken a significant step toward protecting human health. The question of how methylmercury, an organic form of mercury, is produced by natural processes in the environment has stumped scientists for decades, but a team comprised of four researchers at UT has solved the puzzle.

New Leader Named to UT-ORNL Supercomputer Center

Tony Mezzacappa

Tony Mezzacappa, a leader in the field of astrophysics and supernova science, has been named director of the Joint Institute for Computational Sciences at UT and Oak Ridge National Laboratory. Mezzacappa is a world leader in computational astrophysics and a pioneer in the field of supernova science.

UT Study: Unexpected Microbes Fighting Harmful Greenhouse Gas

The environment has a more formidable opponent than carbon dioxide. Another greenhouse gas, nitrous oxide, is 300 times more potent and also destroys the ozone layer each time it is released into the atmosphere. Luckily, nature has a larger army than previously thought combating this greenhouse gas—according to a study by Frank Loeffler, Governor’s Chair for Microbiology, and his colleagues.
