KNOXVILLE—High-entropy alloys—substances constructed with equivalent quantities of five or more metals—might hold the key to future manufacturing and construction, and two researchers from the University of Tennessee in Knoxville could help pave the way.

Doctoral candidate Louis Santodonato, along with his adviser Professor Peter Liaw, both in materials science, did an extensive study into this class of materials, which are considerably lighter and less prone to fracture, corrosion, and oxidation than conventional alloys.

The pair used various methods to observe and model the atomic mixing behavior of high-entropy alloys, work that was picked up by the prestigious journal Nature Communications. [Read more…]

Leading experts present challenges during ORAU annual meeting

Today’s scientists working with big data to identify the next breakthrough in medical care, environmental solutions, or other critical areas need to be skillful in data analytics but also adept at communications. That was one of the key insights attendees heard recently at ORAU’s 70th annual meeting of its Council of Sponsoring Institutions, titled “Big Data Analytics: Challenges and Opportunities.”

“For science to prosper, the science-society relationship must be positive and strong,” said keynote speaker Alan Leshner, chief executive officer emeritus for the American Association for the Advancement of Science, or AAAS. Leshner, who holds a doctorate in physiological psychology from Rutgers University, told the audience that many scientists are not prepared to talk about their work and its implications with the public.

When Deputy Secretary of Energy Elizabeth Sherwood-Randall was in Oak Ridge last week, she met two “Calutron Girls” at the Y-12 National Security Complex.

Peggy Stuart and Ruth Huddleston both came to Y-12 when they were 18 years old. They both were recruited as seniors in high school when someone from Oak Ridge, a place Peggy did not know existed, came to their schools and invited them to join the war effort.

Peggy said: “My friend had worked there and got lonesome for home in Sneedville, Tennessee. When she decided to go back to Oak Ridge, I came with her. They did not hire her because she did not stay when she was there before, but I got a job.”

Ruth was living in Oliver Springs. When the Manhattan Project began, she knew that something big was happening, so she applied for a job and got it. Peggy and Ruth both married and have spent most of their lives in this area. [Read more…]
