Cracking cases
A group of nuclear detectives at the Department of Energy's Oak Ridge National Laboratory takes on tough challenges, from detecting illicit uranium using isotopic 'fingerprints' to investigating Presidential assassination conspiracies. 'A very big capability at Oak Ridge exists for nuclear analytics, all the way from helping commercial production of nuclear power to making sure the world's nuclear materials are properly accounted for,' said ORNL's Joseph Giaquinto, leader of the Nuclear Analytical Chemistry and Isotopics Laboratories.

ORNL researchers use neutrons to gain insight into battery inefficiency
Scientists at Oak Ridge National Laboratory are improving the lifetimes of rechargeable batteries that run on lithium, a small atom that can pack tightly into graphite anode materials. The valuable ions are depleted as a battery charges, and they are also lost to the formation of a thin coating on a battery's anode during initial charging. ORNL researchers used two powerful neutron science facilities to try to understand the dynamics behind this phenomenon.

ORNL's thermal cameras snoop beneath surfaces to reveal materials' secrets
In 1995, the Department of Energy's Continuous Fiber Ceramic Composite program, led by Oak Ridge National Laboratory, bought a high-speed infrared camera -- one of the first available for purchase outside the military. Since then, ORNL has acquired at least 10 additional IR cameras for use in a spectrum of projects. The cameras have mapped changing temperatures as heat flows through objects from gears to artwork.

Laser spectroscopy of ultrathin semiconductor reveals rise of 'trion' quasiparticles
Scientists at the Department of Energy's Oak Ridge National Laboratory used ultrafast laser spectroscopy at the Center for Nanophase Materials Sciences to demystify the dynamics of the negative trions. They explored the behavior of the charged quasiparticle in a two-dimensional semiconductor that is an excellent absorber of sunlight. Their insights, published in the journal Physical Review B, may prove important for advancing technologies for solar energy and quantum computing.

Titan helps unpuzzle decades-old plutonium perplexities
First produced in 1940, plutonium is one of the most electronically complicated elements on Earth -- and because of its complexities, scientists have been struggling to prove the existence of its magnetic properties ever since. Finally, that struggle is over, thanks to a timely combination of theory, algorithm and code developments, neutrons experiments, and Titan -- the second-most-powerful supercomputer in the world.

Carbon number crunching
A booming economy and population led China to emerge in 2006 as the global leader in fossil-fuel carbon emissions, a distinction it still maintains. But exactly how much carbon China releases has been a topic of debate, with recent estimates varying by as much as 15 percent.

Viral comparisons
An Oak Ridge National Laboratory team of comparative genomics and computational science researchers compared approximately 4,000 complete virus genomes downloaded from a public database known as GenBank. By compressing the sequence files, the team created a virus dendrogram that maps out the relationships among all the different virus families.

The pressure is on
Researchers with Oak Ridge National Laboratory's Spallation Neutron Source have developed technology to squeeze materials with a million times the pressure of the earth's atmosphere while studying them with neutrons. When they bombard these materials with neutrons, the materials provide an unprecedented picture of the changing nature of matter under extreme pressure.

Eyes on the prize
Recently, the Department of Energy Office of Science's Nanoscale Science Research Centers at Argonne, Brookhaven, Lawrence Berkeley, Los Alamos/Sandia and Oak Ridge national laboratories jointly organized a workshop at Oak Ridge National Laboratory to discuss opportunities and challenges as imaging and data sciences merge. Those efforts will likely aid the Materials Genome Initiative, which aims to speed new materials to the global marketplace.

Rigors of the road: ORNL invention will support licensing and transport of spent nuclear fuel
With support from the US Nuclear Regulatory Commission, researchers at the Department of Energy's Oak Ridge National Laboratory have devised the Cyclic Integrated Reversible-bending Fatigue Tester. Combined with ongoing fuel transportation research, data from the CIRFT system will help facilitate cask designs and transportation protocols that ensure safe transportation of spent nuclear fuel.

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.

ORNL group leads calorimeter upgrade for Large Hadron Collider experiment
Run-2 for the Large Hadron Collider -- the world's largest and most powerful particle collider -- began April 5 at CERN. In preparation, Thomas M. Cormier, who leads the LHC Heavy Ion group at Oak Ridge National Laboratory, led an upgrade of the electromagnetic calorimeter used for LHC's experiment called ALICE (for A Large Ion Collider Experiment). This detector measures the energies of high-energy electrons and gamma rays emitted from the quark-gluon plasma.
