US Department of Energy National Science Bowl

Back to EurekAlert! A Service of the American Association for the Advancement of Science



ORNL is a multiprogram science and technology laboratory managed for the U.S. Department of Energy by UT-Battelle, LLC. Scientists and engineers at ORNL conduct basic and applied research and development to create scientific knowledge solutions that strengthen the nation's leadership in key areas of science; increase the availability of clean, abundant energy; restore and protect the environment; and contribute to national security.

ORNL also performs other work for the Department of Energy, including isotope production, information management, and technical program management, and provides research and technical assistance to other organizations.



The 'why' of models

The 'why' of models

An international team of researchers from Oak Ridge National Laboratory, Macquarie University, the University of Western Sydney and the Max Planck Institute for Biogeochemistry set out to assess how two Free-Air CO2 Enrichment projects compared to eleven vegetation models that simulate various ecological processes. Instead of only benchmarking whether or not an individual model matched the experimental data, the researchers developed an 'assumption-centered' approach to evaluate why certain models performed better than others.

Shape-shifting plastic

Researchers from Oak Ridge National Laboratory, Washington State University and the University of Idaho have developed a process to make a thermoset that can be reshaped and reused. The new plastic is a shape-memory polymer, so named because the material can 'remember' its original shape and return to it after being deformed with heat or other forces.
