Theory and experiment push each other to expand the frontiers of physics. Now, the Neutron Sciences Directorate at the Department of Energy’s Oak Ridge National Laboratory has both. Cristian Batista, a theoretical condensed matter physicist with a joint appointment at ORNL and th...

Sitting in the driver’s seat comes naturally to Ron Graves, the recently retired head of Oak Ridge National Laboratory’s sustainable transportation program. Graves has logged more than 100 days on national racetracks like Daytona, Road Atlanta, and Pocono where he routinely reache...

Simon Pallin

A scientist that sings opera and performs in musical theater? Sure. If you're a Renaissance Man like Simon Pallin. Pallin is a researcher in Oak Ridge National Laboratory’s Buildings Technologies Research & Integration Center. But his early interests and activities reveal a versatile person that could have chosen a number of occupations.

Illustration shows the one dimensional Yb ion chain in the quantum magnet Yb2Pt2Pb. The Yb orbitals are depicted as the iso-surfaces, and the green arrows indicate the antiferromagnetically aligned Yb magnetic moments.
A new study by a multi-institutional team, led by researchers from Brookhaven National Laboratory and Stony Brook University, has revealed exotic magnetic properties in a rare-earth based intermetallic compound. Similar studies suggest a better understanding of those types of behavio...
A 3D structure of the HIV-1 protease in cartoon representation with bound clinical drug darunavir (shown as sticks).
A team led by the Department of Energy’s Oak Ridge National Laboratory used neutron analysis to better understand a protein implicated in the replication of HIV, the retrovirus that causes AIDS. The enzyme, known as HIV-1 protease, is a key drug target for HIV and AIDS therapies. &nbs...

Ask a biofuel researcher to name the single greatest technical barrier to cost-effective ethanol, and you’re likely to receive a one-word response: lignin. Cellulosic ethanol—fuel derived from woody plants and waste biomass—has the potential to become an affordable, renew...
In pure water, lignin adopts a globular conformation (left) that aggregates on cellulose and blocks enzymes. In a THF-water cosolvent, lignin adopts coil conformations (right) that are easier to remove during pretreatment.
When the Ford Motor Company’s first automobile, the Model T, debuted in 1908, it ran on a corn-derived biofuel called ethanol, a substance Henry Ford dubbed “the fuel of the future.”
In situ neutron diffraction visualizes the synthesis mechanism, involving multi-phase evolutions, of garnet-type fast lithium-ion solid conductors. The neutron diffraction determines the lithium vacancy distribution in the garnet lattice, and reveals the
Although they don’t currently have as much conductivity, solid-state electrolytes designed for lithium-ion batteries (LIBs) are emerging as a safer alternative to their more prevalent—sometimes flammable—liquid-electrolyte counterparts. However, a new study conducted at Oak Ridg...
Using high-performance computing, ORNL researchers are modelling the atomic structure of new alloys to select the best candidates for physical experimentation.

The Department of Energy’s Oak Ridge National Laboratory, FCA US LLC, and the foundry giant, Nemak of Mexico, are combining their strengths to create lightweight powertrain materials that will help the auto industry speed past the technological
